Description

The present invention relates to a stucco coating technique that eliminates difficulties associated with various surface coatings of buildings and the like due to the use of a trowel for kneading and manufacturing of plaster at a conventional stucco coating site.
More specifically, each time a plaster coating is required, the materials for plaster are kneaded in consideration of the amount used, the materials used, etc. to produce a plaster having aqueous, adhesive, plasticity, etc., and the plaster is air Using a trowel or other coating tool within the time when the air-curing hardly progresses due to the carbon dioxide gas in the inside, the desired coating is completed on a generally large area, smooth surface such as the ceiling of the building, the inner and outer wall surfaces, etc. Instead of the conventional plaster painting technology that has to be complicated and difficult, mass production of kneaded materials with desired characteristics in advance, mass production of uncured stucco processed sheets, and so that air curing does not progress The technology to hold it, the technology to take out the sheet every time a stucco coating surface is required and stick it so that it has a paint-like appearance on the required surface, gaps or overlaps between the sheets that are stuck side by side remain No technology, deformation, damage to the surface of the sheet, It relates to the field of technology that uses uncured stucco processed sheets, providing simple modification technology that can recover even if damage etc. occur, technology that allows these sticking and modification to be easily completed before air curing of plaster Is.

The present invention relates to a technical field of providing an art material for drawing frescoes using the surface of uncured hardened plaster, in addition to an advanced technical field of using plaster, a building material technical field using this technology.
An important problem in fresco drawing using the uncured stucco surface is that drawing is completed within a limited time until the stucco containing slaked lime is air-cured by carbon dioxide in the air. Therefore, it is necessary to prepare an uncured image material every time drawing is performed.
The present invention omits the preparation process of stucco paint and the painting material manufacturing process in the original fresco drawing technology including uncured stucco painting technology for the sake of convenience, and only draws with paint for the lower grades of elementary and junior high school The present invention belongs to the field of technology capable of providing a desired amount of painting material at any time and without any complexity.

For finish painting of interior and exterior walls and ceilings of various structures including buildings, the use of thick plaster (a plaster composition) as a coating material has been favored since ancient times. In addition to the complexity associated with the preparation of coating materials in a state where the air-curing reaction has been suppressed, smoothness and peculiarities of stucco coating, various restrictions on the training of workers with advanced coating technologies such as thin coating, and the coating work conditions are drying of stucco It is no exaggeration to say that the characteristics of stucco, which affects the speed and the rate of gas-curing reaction by carbon dioxide in the air, have slowed the development of stucco coating technology.
More specifically, the preparation of the plaster coating material and the subsequent painting are all on-site work, and the work efficiency and quality are subject to natural conditions such as the climate and weather, the area of the painting object, the wall height, etc. It was difficult to obtain painted inner and outer walls that have reproducibility in flatness and have no remaining boundary lines, depending on the conditions of objects, workers' skills, experience, technology, and other factors. .
As a characteristic of plaster coating materials, plaster has a low viscosity, so there is a limit to the thickness of a single coating. If the coating thickness is too large, the coated surface will flow and a uniform thickness cannot be applied. It can be pointed out that there is a trouble that the coating thickness must be reduced and the number of coatings must be increased.
On the other hand, with regard to work technology, due to social changes and changes in the times, the number of plastering engineers involved in various types of painting including stucco coating has decreased, and this tendency is particularly seen in the field of stucco coating that requires advanced technology. Is strong.
As a result, it is considered that the plaster coating itself has decreased despite the fact that a painted wall surface having a heavy appearance is obtained.

Recently, a technology of a building board material in which a prefabricated platy body and a synthetic resin film layer such as a water-based acrylic silicon resin and a fluororesin are laminated has been disclosed (Japanese Patent Laid-Open No. 11-10093). It is difficult to pre-manufacture the plaster plate itself of the appropriate thickness in advance, and the plaster plate portion has already been air-cured and is valuable as a single building plate. However, a boundary line is always formed at the abutting part between the plate-like bodies, and there is a great possibility that various problems due to rainwater intrusion will occur unless proper joint treatment is performed. Remain. In this joint treatment, it must be said that problems such as selection and preparation of treatment materials, treatment work, appearance after treatment, and the like remain.
In addition, instead of the above-mentioned butt-jointing method, there is also a method of making a narrow overlapping part under a flexible state and pressurizing and expanding the swelled part by the overlapping, but conventional plaster lacks fluidity Can't take a satisfactory connection method.

On the other hand, instead of painted walls that use plaster or other coating materials, affixed walls that use wall materials such as concentrated mass-produced synthetic resin plates in factories have emerged and are widely adopted. It became so.
However, when a synthetic resin plate is used for an indoor wall, the type of the synthetic resin, the additive, the type of constituent material of the plate, and the attachment of the plate to a building structure Depending on the type of adhesive, a volatile substance that harms the health of residents is volatilized, and it comes out indoors and causes a disease called so-called sick house syndrome. For example, formaldehyde and other volatile organic compounds (VOC) There is a strong demand for measures to prevent occurrence or avoid use as a material.
For diseases such as sick house syndrome, similar problems have occurred not only with the use of the above-mentioned synthetic resin plate, but also when using synthetic resin or synthetic resin-containing coating materials. Need to be established.

Based on this technical background, the use of plaster, which is harmless to the health of residents, has been reviewed in terms of materials, and research into plaster plates that attempt to solve the above technical problems has been observed. It came to be able to.
However, even if a method of mass-producing plaster plate-like bodies in advance at a factory is used, it is difficult to produce an air-cured plaster plate-like body having a predetermined width and thickness as described in the above-mentioned known example. In addition, the joint boundary line that occurs when a plurality of air-cured plaster plates with a predetermined shape are laid down together is a problem of unsightly appearance of the entire building or a wide area of rainwater. It is necessary to use an appropriate joint material, and problems such as removal of dirt on the surface of the plate-like body generated during work, repair of damaged parts, complexity, etc. remain. These are currently unsolved.

On the other hand, “Fresco” has already been explained and introduced in many literatures, but the most recent book “Invitation to Fresco” (published by Aya Ono, published by Iwanami Shoten) is easy to understand and detailed. Explained.
Here, “Fresco” means “fresh” and “brilliant” in Italian, and also means “Fresco” and “Fresco”.
Furthermore, “Fresco” is understood to include “a phenomenon in which slaked lime crystallizes in the air, that is, a picture made with lime carbonation” and “a picture drawn with slaked lime as a base”.
The term “fresco” used in the present invention means a painting according to the explanation of the above book.

  Here, problems in fresco drawing will be described. To draw frescoes that have been introduced so far, it is necessary to prepare slaked lime-based painting materials at the drawing site every time it is drawn. More specifically, undried paste-like slaked lime (similar to uncured stucco) Is applied to the upper surface of a flat plate such as a plate material or the surface of a curved molded product to obtain a drawing material, but paste-like slaked lime consisting of water and quicklime is exposed to the air. In addition to drying, calcium carbonate is generated by a chemical reaction with carbon dioxide in the air, and there is a problem that it is impossible to draw a fresco using the characteristics of pasty slaked lime. The rate of this air curing reaction is relatively high, and it is said that the surface air curing proceeds in about 24 hours, and drawing must be completed before the air curing with carbon dioxide gas is completed. On the other hand, the preparation of the paste-like material and the troublesome preparation work of application work for the production of the painting material is necessary, and the work has to be carried out every time drawing is performed. It seems that this was a big barrier to learning frescoes in the lower grades.

By the way, there are two broad types of frescoes in the broad sense currently used in Japan. One is called Buon frescoes, which use painting materials made of undried pasty slaked lime with a drawing surface. By using this undried slaked lime, the paint, which is a pigment for drawing, can be fixed to the painting material without a binder (adhesive), and a gas-cured reaction product of slaked lime is formed in the form of a film on the surface of the paint for many years. It is said to be excellent in the preservation of the moon. The present invention is directed to an art material used in this narrowly-defined Buon fresco.
The other painting material is a dry lime-based painting material that uses a binder to attach a drawing pigment and is called Fresco-Secco. However, this art material is considered inferior to Buon fresco in terms of binder deterioration.

  Therefore, the subject of this invention is provision of the technique which concerns on the sheet | seat made from the uncured hardening plaster which uses plaster as a material first, specifically, the sheet | seat made from uncured hardening plaster using an uncooled hardening plaster beforehand It can be mass-produced at the factory, can maintain the uncured state of the plaster sheet for a long time, and provides technology that makes it easy to use the plaster sheet. Secondly, the uncured plaster sheet is used as a building material By doing so, it is possible to eliminate the occurrence of boundary lines as in the case of using a conventional air-cured plaster plate-like body, as well as when using the edges overlapped thinly, resulting in an unsightly appearance. The third is the provision of technology related to building materials with high physical strength that does not leave the possibility of infiltration of rainwater, etc., and that can suppress or repair dirt and damage that are likely to occur after production. Fresco suitable for drawing drawing learning It is to provide a technique according to the drawing for the painting materials.

As a result of diligent research to solve the above problems, the present inventor first coated all the outer surface of the uncured cured stucco processed sheet with a carbon dioxide low permeability synthetic resin film and sealed the film. By doing so, the uncured stucco processed sheet has a special property that it does not cause a gas curing reaction with carbon dioxide gas over a long period of time and can maintain the state of the original paste-shaped uncured stucco processed sheet, Secondly, during this research, as long as the stucco sheet was in an uncured state, it was found that it has thixotropic properties that cause a reversible change between the gel state and the sol state. Therefore, in the gel state based on the properties of the thixotropy, the synthetic resin film for coating is relatively easy to peel, but in the sol state, it is relatively difficult. The property can be solved by taking a coating form using a special film, and thirdly, by adding a net-like reinforcing material in the layer of the uncured cured stucco processed sheet, the strength of the sheet is of course improved by carbon dioxide gas. It is easy to peel off and remove a coating film such as a low-permeability synthetic resin film, and fourth, a laminate of a special embodiment of a short product of a non-cured stucco processed sheet or a spiral laminate of a special feature of a long product By building a body, we can store a large amount of the sheet efficiently, obtain a knowledge that can be provided in large quantities and immediately when necessary, and fifthly target the stucco surface of these uncured stucco processed sheets We found that it was possible to provide building materials that do not require the conventional “trowel” painting method by sticking to objects, and sixthly, supporting these uncured stucco processed sheets with fresco drawing materials The only work adhered to, immediately it becomes possible frescoes drawing learning, give the other findings, the present invention has been completed.

  This invention provides the sheet | seat made from the coating uncured hardening plaster which has the structure of the 1st thru | or 9th invention, the subject on the working technique which the conventional plaster coating technique or a well-known plaster use building material has, etc. The effect that can solve the problems based on the characteristics of the coating material is widely demonstrated, and furthermore, it succeeded in providing the new building material using the plaster coating material and the painting material for fresco drawing in the field of painting art. The effect was great, and the expected effect that the stucco use technology became more prosperous than before was also brought.

Embodiments of the present invention will be described below with reference to the drawings, and the best mode for carrying out the present invention will be described in detail.
In addition, all the following drawings are mainly for facilitating the understanding of the structural features of the coated uncured stucco sheet itself according to the present invention in appearance, and the model neglecting the structural dimensional ratio Shown as a diagram.

FIG. 1 is a partially cutaway perspective view of an example of a coated uncured stucco sheet according to the first invention.
As shown in FIG. 1, the coated uncured stucco sheet 1 is a carbon dioxide gas low permeability synthetic resin film 1B (upper surface is the upper and lower outer surfaces (upper surface is indicated by 1 Aa)) of the uncured stucco processed sheet 1A. 1Ba, the lower surface is indicated by 1Bb), and the outer surface 1Ac of the side surface is all covered with the two films, and the amount of enclosed air (to be precise, the amount of carbon dioxide) is as small as possible. While applying external pressure, the two films are sealed with a heat seal 1Bc.

This tight coating, covering, and sealing under reduced air amount are intended to extremely inhibit the uncured stucco processed sheet 1A from coming into contact with the outside air to dry and proceed with the gas curing reaction by carbon dioxide gas.
Such a coated uncured stucco sheet 1A can be manufactured using various known methods. For example, while supplying a plaster paste between two horizontal rollers having a desired gap in a pressurized and continuous manner, at the same time, two rollers are used as guide rollers, and two carbon dioxide gas low permeability synthetic resins on both outer surfaces By drawing each of the films 1Ba and 1Bb, an uncured stucco sheet with the carbon dioxide low permeability synthetic resin film adhered to both outer surfaces can be continuously produced.
As another simple method, a carbon dioxide gas low permeability synthetic resin film 1Bb is laid on a flat table (conveyor belt or fixed table), and a desired amount of undried and uncured stucco paste is spread on it. Or in the form of a plaster lump, and the upper and outer surfaces thereof are further covered with the same carbon dioxide low-permeability synthetic resin film 1Ba, and the gap between the upper surface film 1Ba and the table is set to a desired value. It can also be obtained by leveling with a roller adjusted and maintained.
However, the present invention is not limited by these production methods.

  On the other hand, since the thickness of the uncured cured stucco processed sheet 1A is relatively thin, the outer surface 1Ac on the side surface of the uncured cured stucco processed sheet is difficult to adopt the above-described adhesion coating method under pressure. However, the carbon dioxide low permeability synthetic resin films 1Ba and 1Bb whose upper and lower outer surfaces are tightly coated are sufficiently extended beyond the outer surface of the side surface, and the sealing seal is under pressure from the outer surface side of both films. In addition, it is preferable to carry out under reduced pressure of the space between the two films or under substitution with another gas that does not cause air hardening of the stucco in terms of preventing or delaying the air hardening of the stucco component.

  In covering the non-cured stucco processed sheet 1A with the carbon dioxide low-permeability synthetic resin film 1B in the above description and sealing the film, two films 1Ba and 1Bb on the upper and lower surfaces are used. There is no problem with the method of covering the periphery so as to be wound around. In a special case, use of a method in which an uncured stucco mass is placed in a tubular inflation film and spread in the tubular film is also one of preferred embodiments.

The coated uncured stucco sheet 1 may be long, short, wide, or narrow, but when used in a building or the like, the width of the place of use is, of course, a plurality of the sheets. It is preferable to select so that the formation of a connecting portion (typically a butting portion or an overlapping portion) between sheets is minimized.
However, in the case of the uncured cured plaster processed sheet according to the present invention, the butted portions or the overlapping portions of the two sheets 1A and 1A are undried uncured cured plaster processed sheets. Can be eliminated by leveling work and caulking work (may be an effect based on the thixotropy characteristics), so that it is impossible to form the butt portion or the like, or joint materials with special dimensions and shapes. There is no need to prepare.

The plaster used for the production of the uncured hardened plaster processed sheet 1A is conventionally known as plaster for plasterers, and has been used for painting ceilings, internal and external walls of buildings, or various types of plaster that have been proposed for improvement. The system material can be applied as it is, and is not particularly limited.
Slaked lime Ca (OH) ₂ which is the main raw material of plaster can be obtained by calcining limestone CaCO ₃ at 900 to 1200 ° C. to obtain quick lime, and adding water thereto. Here, limestone is mainly used as limestone, but shells such as cocoons and oysters can be used instead of limestone, and slaked lime shell ash produced using these shells is useful for improving the characteristics of stucco.

In order to improve the workability of plasterers, “Nori” is usually added to plaster, but it is a water-soluble polymer in addition to seaweed paste made from “Kakumata”, “Ginkgo”, “Funari”, etc. Chemical glues such as certain methylcellulose and polyvinyl alcohol are generally known.
Furthermore, for the purpose of preventing cracking of a thin layer of plaster that tends to occur after painting, such as walls, a stucco reinforcing material called “susa” is added to the plaster. As this reinforcing material, a short fiber is usually used, and vegetable fibers (Japanese paper, Manila hemp, shiro, wood pulp, etc.) and chemical fibers (synthetic fibers, carbon fibers, glass fibers, etc.) are common. is there.

  The main components constituting the plaster composition are usually plaster, water, glue, and suspension, but depending on the purpose of the plaster coating, components having other functions may be added. The component ratio is not particularly limited, but a paste having a viscosity that facilitates ironing and leveling with a trowel, roller, bar or the like is preferable. Since it cannot be used at such a viscosity that it can flow easily like water and cannot maintain the state as a stucco sheet, usually 50 to 120 parts by weight of water to 100 parts by weight of slaked lime, 0.5 to 1.5 parts by weight of paste, A range of about 0.5 to 2.0 parts by weight is preferably used, but the present invention is not limited by these composition ratios.

The composition of the above-mentioned stucco is formed into an uncured cured stucco processed sheet of various thicknesses in an uncured paste state, and the thickness of the sheet is not particularly limited, and is intended for use It is appropriately selected and used depending on.
However, it is stocked and stored in the form of a coated uncured stucco sheet, and when taking out a large area as necessary, in terms of prevention of breakage of the uncured stucco processed sheet, handling suitability such as transportation, etc. Usually, a relatively thin uncured stucco processed sheet of about 1 to 5 mm (thickness) is preferable, about 2 to 5 mm is more preferable, and about 2 to 3 mm is particularly preferable. In addition, when the storage mode as described later is roll winding, the deformation when drawn out as the difference between the inner and outer circumferences becomes more severe, so about 1 to 2 mm is preferable, but about 1 to 1.5 mm is particularly preferable. .
In addition, in special cases, for example, if there is a terrible unevenness on a wide surface to be adhered to, such as a building, and if you want to flatten the entire surface, make the thickness of the uncured stucco processed sheet 1A as large as possible, Although it is preferable to have a leveling allowance due to the “trowel”, the thickness of such a coated uncured stucco sheet is not limited in the present invention.

  Here, the carbon dioxide gas low permeability synthetic resin film is sufficient as long as it is optically non-porous, for example, a known synthetic resin film such as polyester resin, polyvinyl chloride resin, polyvinylidene chloride resin, polyamide resin, polyolefin. Resins, polyethylene-vinyl acetate resins, polyvinyl alcohol resins, cellulose acetate resins and the like can be preferably used.

FIG. 2 is a cut end view of an example of the coated uncured stucco sheet according to the first invention, and shows the XX cut end view of FIG. 1.
The carbon dioxide gas low permeability synthetic resin film 2B (2Ba on the upper and outer surface side and 2Bb on the lower outer surface side) in the coated uncured stucco sheet 2 is the upper and lower outer surfaces 2Aa and 2Ab of the uncured stucco processed sheet 2A. The outer surface 2Ac of the side surface is covered, and the outer cover 2Ac is used to seal the entire coating film (that is, the seal portion is 2Bc). Although it is for suppressing the reaction which touches 2A and raise | generates the air hardening of the stucco component, it pastes the non-air hardening stucco processed sheet 2A of the sheet | seat 2 made from coating | curing uncured hardening plaster on the surface of buildings etc. as mentioned later. When wearing, first the film 2Ba on the upper and outer surface side is peeled and removed, and the upper and outer surface 2Aa of the uncured stucco processed sheet lined with the film 2Bb on the lower outer surface side is pasted on the surface of the building or the like. Wearing, then under Side of the film 2Bb is also peeled and removed.
At this time, management of the peeled state between the uncured cured stucco sheet 2A and the films 2Ba, 2Bb is important, and the roughness of the sheet outer surface 2Aa seen at the time of removing the upper and outer surface side film 2Ba is as follows: This is a rough surface to be attached to the surface of a building or the like, and is not a big problem. However, a phenomenon in which stucco is likely to adhere to the upper and outer surface film 2Ba is observed.
Contrary to the above case, especially the surface that is not adhered to the surface of a building or the like, in the above example, the peeling surface of the lower outer surface side film 2Bb is a surface that affects the appearance, and the peeling state is particularly important and rough There is a need for a stripping mode that does not result in a wet state. If the condition becomes rough, a leveling operation using a “trowel” is required, but this is the reason why an unnecessary means for the “trowel” operation, which is complicated and requires heavy labor, is required.

The roughness of the uncured cured stucco sheet 2A when peeling the upper and lower outer surface side films 2Ba and 2Bb is the sol state of the uncured cured plaster sheet 2A after creating the coated uncured plaster sheet 2. The period is likely to occur because of the high adhesion of plaster to the adhesive coating film 2B. Conversely, when a considerable amount of time has elapsed after the creation of the coated uncured stucco sheet 2, the uncured stucco processed sheet 2A is in a gel state. It was observed that the film 2B was easily peeled off, and the surface of the sheet was hardly roughened.
As a result of various studies, the present inventors have found that the stucco paste has thixotropy characteristics as described above, and have come to consider that this is based on the reversible change of the stucco gel-sol, As a result, the period after the production of the coated uncured stucco sheet 2, the peeling time of the upper and lower films 2Ba, 2Bb is important, and the problem is solved by selecting an appropriate peeling time depending on the composition of the stucco. I came to find it.

By the invention of this solution, in the case of the coated uncured stucco sheet 2 configured as shown in FIG. 2, immediately after the production of the sheet or for a short period of time, it is not attached to the surface of at least a building, It is preferable to avoid peeling and removal of the coating film 2Bb on the surface that becomes the outer surface.
On the contrary, when a considerable time has passed after the production of the sheet 2, it can be said that the covering films 2Ba and 2Bb can be easily peeled off.
In addition, since the elapsed time suitable for peeling of the coating film 2B is considerably influenced by the composition of the stucco and cannot be specified unconditionally, the state of the uncured stucco processed sheet (gel based on thixotropic characteristics, sol state) is observed. It is preferable to judge.

FIG. 3 shows one embodiment of the second invention for solving the problem of peelability of the carbon dioxide low permeability synthetic resin film in the first invention described in FIG. Cut end view of the sheet 3 made of coated uncured stucco, in which the entire coated film covering the outer surface 3Ac of the side surface is sealed (sealed portion 3Bc) in addition to the adhesion coating of the upper and lower outer surfaces 3Aa, 3Ab of the plastered sheet 3A Indicates.
Depending on the state of the gel or sol of the uncured stucco processed sheet 3A, the peeling surname of the carbon dioxide low permeability synthetic resin film 3B (upper outer surface side: 3Ba, lower outer surface side: 3Bb) changes, especially the uncured cured stucco coated During the period when the elapsed time after forming the sheet 3 is short, the peeling surrounding of the covering film 3B is bad.

In order to solve this problem, FIG. 3 shows a synthetic resin sheet 3C (3Ca on the 3Aa surface and 3Cb on the 3Ab surface) having liquid-permeable pores on the upper and lower outer surfaces 3Aa and 3Ab. In other words, the peelability of the carbon dioxide low permeability synthetic resin film 3B (upper outer surface side: 3Ba, lower outer surface side: 3Bb) is remarkably improved.
The reason for such an improvement in peelability is not always clear, but the liquid component of the uncured cured stucco sheet 3A passes through the pores of the synthetic resin sheet 3C having the liquid-permeable pores, and the carbon dioxide gas is low. It is presumed that the permeable synthetic resin films 3Ba and 3Bb may ooze out to the inner surfaces 3Bd and 3Be. If exudate is present, it is easy to think that both films are easy to peel off.
When exuding the liquid component, it is preferable to select pores that suppress the exudation of the solid component of the stucco as much as possible and to increase the amount of the liquid component. This is because the exudation of the solid component adheres to the carbon dioxide gas low permeability synthetic resin film 3B and lowers the peelability.

Following the removal of the carbon dioxide low permeability synthetic resin film 3B, the removal of the synthetic resin sheet 3C from the upper and lower outer surfaces 3Aa and 3Ab of the uncured cured plaster processed sheet is relatively easy, and the sheet 3A. The surface 3Aa, 3Ab can be made almost without roughening.
The reason for this is that, similarly to the estimation of the peelability of the carbon dioxide gas low permeability synthetic resin film 3B, through the pores of the synthetic resin sheets 3Ca, 3Cb, to the uncured stucco processed sheet outer surface 3Aa, 3Ab side of the inner surface of the sheet It is thought that this is because air flows and an air layer is formed.

The synthetic resin sheet 3C having liquid-permeable pores mentioned here has a lot of pores having a liquid, especially aqueous liquid permeability, on a synthetic resin ultra-thin film, for example, having a thickness of about 5 to 20 μm. A synthetic resin woven fabric or non-woven fabric having a large number of fine eyes is suitable, but a carbon dioxide gas low permeability synthetic resin film 3B can also be used.
The reason why the permeability of the liquid component is a requirement as described above is that the sheet 3C is included in the uncured stucco-processed sheet 3A as long as the solid component of the stucco paste can pass freely. This is because the original function of the sheet cannot be exhibited.

In addition, prior to the coating of the non-cured stucco processed sheet 3A as shown in FIG. 3 with the carbon dioxide low-permeability film 3B, a coated uncured stucco sheet having a structure in which the synthetic resin sheet 3C is closely adhered is also illustrated in FIG. It can be manufactured by a method similar to the manufacturing method shown in the description of.
Furthermore, when the synthetic resin sheet 3C having liquid-permeable pores referred to in the present invention is not used, it has been observed that the peelability is somewhat improved by increasing the amount of the “susa” component in the plaster.

FIG. 4 shows a process in which the carbon dioxide gas low permeability synthetic resin film 3Ba on the upper and outer surfaces and the synthetic resin sheet 3Ca on the upper and outer surfaces are sequentially peeled from the coated uncured stucco sheet 3 shown in FIG. An end view is shown.
In peeling, it is necessary to first cut and remove the seal portions 3Bc at both ends, and then the film 3Ba and the sheet 3Ca are sequentially peeled and removed, but the carbon dioxide gas low permeability synthetic resin film 3Ba on the synthetic resin sheet 3Ca side is removed. No adhesion of the uncured stucco processed sheet was observed on the surface 3Bd, and it can be seen that the peeling proceeded easily.
Moreover, even when the synthetic resin sheet 3Ca was peeled and removed, rough skin based on the peeling and removal was not observed on the upper and outer surfaces 3Aa of the uncured cured plaster processed sheet.
In FIG. 4, 3C is a synthetic resin sheet, 3Bb is a low-permeability carbon dioxide synthetic resin film on the lower outer surface, 3Cb is a synthetic resin sheet on the lower outer surface, and 3Ab is an uncured stucco processed sheet. On the outer surface, 3Be indicates the surface of the synthetic resin sheet 3Cb side of the carbon dioxide gas low permeability synthetic resin film.

FIG. 5 relates to the coated uncured stucco sheet 4 according to the third invention, and the embodiment shown in FIG. 3 (however, the synthetic resin sheet 4C is only 4Ca on the upper and outer surfaces of the uncured stucco processed sheet. It is related with the sheet | seat 4 made from the coating uncured hardening plaster of the aspect which added another function to the thing which intervened as FIG. 3, and is shown with the cut end view similar to FIG.
Specifically, the strength of the uncured plaster-processed sheet 4A, particularly weather resistance, water resistance, physical strength (used to reduce damage over time such as cracks as much as possible) when used on buildings, etc. In order to improve the quality of the sheet, and to impart a characteristic that the plaster does not easily adhere to the “trowel” during the operation by the “trowel”, the plaster permeable reticulated reinforcing material 4D is embedded in the layer of the sheet 4A. A plaster sheet 4 is shown.

The reticulated reinforcing material 4D of the uncured stucco processed sheet 4A is a reticulated material having water resistance and high strength in terms of physical properties, such as a net made of synthetic resin fiber or twisted yarn or metal strip, non-woven fabric, It refers to a woven fabric or the like that has large communication holes that can pass through the solid components of the plastered sheet across the front and back. It is fundamentally different from the synthetic resin sheet 4C having the liquid-permeable pores in that it has such communication holes.
As the material of the synthetic resin fiber, polyester, polyvinyl chloride, carbon fiber and the like are particularly preferable.

As a method of embedding these reticulated reinforcing materials 4D in the layer of the uncured cured stucco processed sheet 4A as shown in FIG. 5, various means are conceivable using a known technique, as shown in the description of FIG. Using a roller, two nozzles parallel to the roller are installed above the gap between the two rollers, and the mesh reinforcement 4D is supplied between the thin plaster paste sheets extruded from the two nozzles. A method of covering both outer surfaces with the synthetic resin sheet 4C and the two carbon dioxide gas low permeability synthetic resin films 4Ba and 4Bb while sandwiching is preferable.
As another method, a synthetic resin sheet 4Ca is laid on the coating film 4Ba, and a thin plaster sheet 4A, a net-like reinforcing material 4D, a thin plaster sheet 4A similar to the above, and a coating are formed thereon. The method of obtaining the coated uncured stucco sheet 4 by sequentially stacking the film 4Bb for use and then applying pressure from the outer surface with a “trowel” or the like under pressure is the simplest and most easily adopted as a batch method.
The lower surface 4Bd of the carbon dioxide low permeability synthetic resin film 4Ba and the upper and outer surfaces 4Aa of the uncured stucco processed sheet 4A are in intimate contact with the synthetic resin sheet 4Ca, and the lower outer surface 4Ab of the uncured cured plaster processed sheet 4A. Is covered with carbon dioxide gas low permeability synthetic resin film 4Bb, and carbon dioxide gas low permeability synthetic resin films 4Ba and 4Bb on the upper and lower outer surfaces form the same seal portion 4Bc as described above.

FIG. 6 shows a cut end view of the coated uncured stucco sheet according to the fourth invention, which is manufactured one by one as described above when a large amount of uncured stucco processed sheet is required at the same time. The cut end view of the sheet | seat made from the coating un-air hardening stucco of the new structure which improved the inefficiency of supply of the coated un-air hardening stucco sheet was shown.
Covered uncured stucco sheets of various configurations illustrated in FIG. 2, FIG. 3, and FIG. 5 are formed by sealing each of the uncured cured stucco sheets one by one. When it is necessary to use a large amount at the same time as learning, etc., a large number of uncured stucco processed sheets are coated together and sealed, the uncoated cured stucco sheet is more efficient in terms of production and supply. From the viewpoint of being, among the upper and lower outer surfaces of the coated uncured stucco sheet according to the first, second or third invention, at least the lower outer surface carbon dioxide gas low permeability synthetic resin film 5B is closely coated. The carbon dioxide gas low permeability synthetic resin as a whole is left in the state of a laminated body in which a plurality of uncured stucco processed sheets 5A are stacked without covering the outer surface of the side surface and sealing the entire coating film. Film 5B (top Surface-side 5Ba, covering the lower outer surface side 5Bb), there is provided a formed by sealing (5Bc) coating non-air curing STUCCO sheet, showing the example.

An example of the manufacturing method of the sheet | seat 5 made from the coating uncured hardening plaster illustrated in FIG. 6 is shown.
Covered uncured stucco sheet 4 in FIG. 5 (uses an uncured stucco processed sheet with a synthetic resin film having liquid-permeable pores on one side and a stucco permeable network embedded in the sheet. A plurality of uncured stucco processed sheets 5A having a carbon dioxide gas low permeability synthetic resin film 5B on the lower and outer surfaces of the uncured cured stucco processed sheet 5A without undergoing the sealing process of all films in the production of The whole is covered with a carbon dioxide gas low permeability synthetic resin film 5B (the upper outer surface side is a film 5Ba, and the lower outer surface side is a film 5Bb), and this coating film is sealed (having a sealing portion 5Bc). An uncured stucco sheet 5 is provided.
In addition, in order to improve releasability between each uncured cured plaster sheet 5A and the carbon dioxide gas low permeability synthetic resin film 5B on the lower and outer surfaces thereof, the lower outer surface of the uncured cured plaster sheet 6A is also provided in advance. It is more preferable that the synthetic resin film having liquid-permeable pores (corresponding to the synthetic resin film 3Cb in FIG. 3) is closely coated.
In the present invention, the lower surface of the uncured stucco-processed sheet 5A is covered with a carbon dioxide gas low permeability synthetic resin film 5B as a constituent requirement. Since it is covered with a resin film and sealed, in order to prevent air-curing of the air-cured stucco-processed sheet that has been sealed and coated, the film 5B on each lower surface must always have low carbon dioxide permeability. It's not that. However, when the seal is released, each sheet is taken out and the stucco surface of the uncured stucco processed sheet is pasted on the object and left as it is for a while (use as building material, used as fresco drawing material) In many cases, it is necessary to prevent air curing of the outer surface of the uncured stucco processed sheet 5A, and the use of a carbon dioxide low permeability synthetic resin film is preferable.

  As described above, after the production of the coated uncured stucco sheet 5, even if it is opened, a large number of uncured stucco processed sheets 5A that are tightly coated with the carbon dioxide low permeability synthetic resin film 4Ba are stacked to form a laminate. Since it comprises, at least the uncured hardened stucco processed sheet below the laminate is also in a state of covering the upper and outer surfaces, so that the air curing rate by carbon dioxide gas has an effect of being slow.

FIG. 7 is an example of a long covered uncured stucco sheet 6 according to the fifth invention, and shows a cut end view thereof. Instead of a mode in which a large number of short sheets shown in FIG. 6 are horizontally stacked, a long uncured stucco processed sheet 6A having a carbon dioxide gas low permeability synthetic resin film 6B on either the upper or lower outer surface is provided. The case where it wraps around the winding core P in multiple rounds is shown.
Specifically, 6A corresponding to the long thing of the uncured hardening stucco processed sheet 2A shown in FIG. 2 which is an example of the sheet | seat made from the coating uncured hardening plaster shown in FIG.2, FIG.3, FIG.5. The carbon dioxide gas low-permeability synthetic resin film 6B on the outer surface of either one of the upper and lower sides is left, and the other film is removed, and is wound around a long sheet winding core tube P in a spiral shape. The whole is covered with a carbon dioxide gas low permeability synthetic resin film 6B (the upper outer surface side is the film 6Ba, and the lower outer surface side is the film 6Bb) and sealed (sealed portion 6Bc).
In addition, the sheet | seat 6A wound in the spiral shape which concerns on this invention can be cut | disconnected to required length, pulling out from the winding edge part after the said opening, and can use for a desired objective.

  The spiral wrapping technique around the core tube P is produced while producing a long sheet having the structure of any one of the various coated uncured stucco sheets 2, 3 and 4 according to the first to third inventions. This is a technology that peels and removes the carbon dioxide gas low permeability synthetic resin film on the upper surface and winds the uncoated surface of the obtained single-side coated sheet in contact with the surface of the core tube, followed by covering and sealing the whole as described above By doing so, there is an advantage that a long coated plaster sheet can be stored in a large amount even in a storage room in a narrow space.

When wound around the core tube, the upper and outer surfaces 6Aa formed by peeling off the carbon dioxide low permeability synthetic resin film 6B on the upper and outer surfaces 6Aa of the uncured cured plaster sheet 6A are brought into contact with the surface of the core tube. By doing so, the upper and outer surfaces 6Aa are in close contact with the surface of the already wound coating film 6B, so that it can be prevented from immediately coming into contact with the outside air, and as a result, a state where it is difficult to be air-cured is obtained.
Since the production of the long sheet 6A (the lower outer surface 6Ab is closely coated with the carbon dioxide gas low permeability synthetic resin film 6B) is almost always performed while continuously wound around the core tube, In many cases, the carbon dioxide gas low permeability synthetic resin film 6B on the outer surface 6Aa side is continuously peeled and removed. In this case, the uncured cured plaster sheet 6A is usually in a sol state. A sheet 3Ca made of synthetic resin having liquid-permeable pores according to the invention is interposed between an uncured cured stucco sheet 6A and a synthetic resin film 6B having a low permeability to carbon dioxide gas, and is adhered and coated on the surface of the sheet 6A. It is desirable to produce a coated uncured stucco sheet of construction. Further, by placing the sheet 3Ca in close contact with the lower and outer surfaces of the uncured stucco processed sheet 6A, the carbon dioxide low permeability synthetic resin film on the lower and outer surfaces of the sheet 6A is more easily peeled and removed. be able to.

  Moreover, since the edge part (side surface) of the uncured cured plaster sheet 6A after being wound around the core tube P is in a state open to the outside air, the surface and the entire side surface of the uncured cured plaster sheet 6A As described above, it is necessary to airtightly package the carbon dioxide gas low permeability synthetic resin film 6B to suppress contact with the outside air.

FIG. 8 shows an example of use of a coated uncured stucco sheet that can be used for building materials according to the sixth or seventh invention, for a building material 7 for forming a plaster coating wall surface, and is a perspective view with a part cut away, similar to FIG. It is.
The sealing portion 2Bc of the coated uncured stucco sheet 2 in FIG. 2 described in the first invention is excised, leaving a carbon dioxide gas low permeability synthetic resin film 2Bb on the lower outer surface, and peeling the film 2Ba on the upper outer surface. It demonstrates corresponding to the uncured hardening stucco processed sheet 2A obtained by removing, and its upper outer surface 2Aa.

  As described with reference to FIG. 7, an arbitrary short or long uncured stucco processed sheet 7A is obtained, and the carbon dioxide gas low permeability synthetic resin film on the upper and outer surfaces of the sheet 7A is peeled and removed. The building material 7 for forming a plaster coating wall surface is formed by pressing the entire surface of the sheet 7A obtained by leaving the carbon dioxide gas low permeability synthetic resin film 7Bb onto the upper and outer surfaces of the sheet 7A, which is bonded to the wall surface W to be processed with the plaster coating. The film 7Ab on the lower outer surface of the sheet 7A is turned upside down, and a plurality of (two in FIG. 8) the building materials 7 are arranged on the outer surface of the wall W with their side surfaces butted. Attach to cover.

Next, the carbon dioxide gas low permeability synthetic resin film 7Bb on the outer surface is gently peeled and removed before the air curing of the plaster proceeds. FIG. 8 is a perspective view when this part is peeled and removed.
Between the two lower outer surfaces 7Ab of the uncured hardened stucco sheet 7A that has appeared due to this peeling and removal, a grooved butted portion G formed by butting appears. However, the groove-like butting portion G is formed by using two leveling tools such as a “trowel” K for the lower outer surface (the lower outer surface before the upper and lower surfaces are reversed) 7Ab of the uncured stucco processed sheet 7A. By squeezing or leveling between the outer surfaces 7Ab, the two can be integrated and the grooved butted portion G can be eliminated. In the work such as leveling, if necessary, the leveling work part may be wetted by slightly spraying water. The effect of this spray is evidence that stucco has not yet been cured.
This leveling effect can also be obtained in the removal when the lower outer surface 7Ab of the uncured cured stucco processed sheet 7A has uneven marks, physical scratches, stains, and the like.

FIG. 9 is a perspective view of the same painting material, showing an example of using the coated uncured stucco sheet according to the eighth or ninth invention to a drawing material for fresco drawing.
As described with reference to FIG. 7, an arbitrary short or long uncured stucco processed sheet 8A can be obtained. FIG. 9 shows the fresco drawing material 8 on the upper surface of the support plate T, and a carbon dioxide gas low permeability synthetic resin. 8A shows a relatively short uncured stucco processed sheet 8A whose outer surface 8Ab is covered with a film 8B. The art material 8 having such a structure opens the coated uncured stucco sheet 2 shown in FIG. 2 according to the first invention, and is a low-carbon dioxide synthetic resin film on the lower outer surface of the uncured stucco processed sheet. , The coating film 2Ba on the upper and outer surfaces is peeled and removed, and as shown in FIG. 9, the support plate T is brought into close contact with the surface and the upper and lower surfaces are reversed, and the carbon dioxide gas low permeability synthetic resin is placed on the support plate T. The uncured stucco processed sheet 8A in which the outer surface 8Ab is covered with the film 8B is formed.
In order to suppress the air curing of the uncured cured stucco processed sheet 8A as much as possible, the opening and the removal of the carbon dioxide gas low permeability synthetic resin film on the upper and outer surfaces are performed immediately before the image material formation and drawing, Further, in order to suppress as much as possible the contact time between the lower outer surface 8Ab of the sheet 8A after removal of the film on the upper outer surface and carbon dioxide, the film on the lower outer surface is preferably removed immediately before the start of drawing.
The art material thus obtained has an uncured hardened stucco processed sheet layer mainly composed of slaked lime component on the outer surface, and as a learning material for drawing Buon fresco drawing, quickly and easily. There is a feature that can supply and use the required amount.

As explained in detail above, the coated uncured stucco sheet according to the present invention is air-cured when the coated uncured stucco sheet is attached to a wall of a building or the like, for example. Even if it is in the gel state, it can be easily solled by applying a slight force, such as lightly squeezing the surface with a trowel, etc., smoothing the surface of the sheet, repairing contaminated parts, 2 sheets In addition to facilitating the leveling process that eliminates the joints between the sheet butting parts or the overlapping parts, it is difficult to paint over a large area using conventional trowels, and is complicated, as well as the problem of reducing the number of paint engineers Will be solved, and it will be a major change and development in the industry related to plaster coating.
In addition, the provision of art materials for drawing frescoes has the effect of making frescoes drawing familiar by eliminating the complexity of material preparation. We can expect the development of a learning material provision industry for lower grade students who are not home.
