Description

  The present invention relates to a building interior finishing material which can be applied to the interior finish surface of a house with a trowel to give a Japanese paper atmosphere.

As a finishing material for building interiors, when Japanese paper is pasted on the walls and ceiling of the interior, it is almost impossible to produce a single piece of Japanese paper with a large wall surface or ceiling surface. ing. Moreover, as shown in Patent Document 1, there is a composition for an interior material that is made into a paste by adding water to a mixture containing pulp as a main component and containing clay, a plant bond, and a plant fungicide.
JP 2002-106139 A

However, when Japanese paper is spliced and stretched on an interior finishing surface such as a wall surface, there is a problem in that the appearance deteriorates because the spliced portion overlaps with adjacent Japanese paper. In addition, when using hand-made Japanese paper, in addition to the above problems, construction is difficult, so there are few craftsmen who can apply it, and the price of hand-made Japanese paper itself is high, so the construction price becomes expensive and demand for ordinary houses is high. There is a problem that many are not expected. Furthermore, although the interior material composition disclosed in Patent Document 1 contains pulp in the raw material, but contains clay, even if this interior material composition is applied to the interior finish surface, There is a problem that it is difficult to create an atmosphere.

The present invention was made in view of the above circumstances, it may look since there is no seaming portion, yet provides interior finish that it is possible to obtain the same quality feeling as when using hand漉和paper It is for the purpose.

A place where the means of the present invention, in the invention of claim 1, and a pulp that has absorbed water main raw material, and that the dried fibers mulberry finely cut into approximately 2mm~5mm auxiliary materials, the mixture Then, paste and kneading water was added to obtain an appropriate viscosity , and the raw fiber of Japanese mulberry cut into a length of 100 mm to 200 mm in the form of string, which is a Japanese paper material , and the unnecessary fiber part of the Japanese paper material In addition, at least one of black skin, straw, and bamboo is mixed to make a building interior finishing material.

  The invention of claim 2 is characterized in that the pulp is a processed product of wood chips, which is a raw material for western paper.

  The invention of claim 3 is characterized in that the pulp is a large sawdust of wood.

  According to the invention of claim 1, since the interior finish is made by applying a predetermined thickness to the wall surface or ceiling surface with a trowel, the joint portions overlap as compared with those using Japanese paper, and the appearance is poor. There is no. In addition, the raw material of the building interior finishing material of the present invention is mainly made of pulp that can be purchased in large quantities at low cost, and the dried Japanese paper material is finely cut and used as an auxiliary material. However, since pulp is used as the main raw material, it can be manufactured inexpensively as a whole. In addition, because the raw fiber of Kozo is used as a raw material for hand-made Japanese paper, an interior finish with a texture similar to that of Japanese paper can be obtained. In addition, when the raw fiber of Kozo is exposed and used, it exhibits a white color, and when it is not exposed, a beige color can be utilized to take advantage of the desired texture. Furthermore, the building interior finish material of the present invention made from such raw materials uses pulp, Japanese paper material fibers, and leather, etc., so the finished interior finish has a more texture than Japanese paper. A certain interior finish can be obtained. Also, since this interior finish material takes time to dry, even if it is not completely painted in a single operation when painting an interior finish such as a large wall surface, it will be damp even if it is applied adjacent to the previously applied location. Therefore, it is easy to become familiar with, and therefore, the entire interior finish surface is finished cleanly without causing a seam as in the case of applying Japanese paper. Furthermore, if a colorant such as a pigment of a suitable color or Bengala is mixed in, a Japanese paper-like interior finish with a desired color can be obtained. Furthermore, since only natural materials are used, the human body is not adversely affected, and the environment is also considered.

  Further, according to the invention of claim 2, since the pulp of the main raw material is a processed wood chip of the raw material of the paper, there is an advantage that it can be easily obtained at a low cost.

  According to invention of Claim 3, since the pulp of the main raw material is the large sawdust of the timber which generate | occur | produces in large quantities at a sawmill etc., there exists an advantage which can be obtained cheaply.

  Embodiments of the present invention will be described below. The building interior finishing material of this invention is a mixture of finely cut dried fibers as an auxiliary material to pulp as a main material, kneaded with water and glue, and further, Kozo raw fibers as a Japanese paper material And at least one of an unnecessary fiber portion of Japanese paper material, black leather, straw, and bamboo.

  The pulp to be used is a wood chip crushed into a predetermined shape as a raw material for paper, and the maximum length is about 0.5 to 1.0 mm. Usually, it is compressed and has a cubic shape with a side of 1 m, for example, and is used in a state where it is divided into a predetermined size and loosened. When the pulp is a powdered paper pulp, it is convenient because the fiber is short but the particles can be used without being processed. In addition to such powder pulp, waste wood and raw wood pulverized to a maximum length of about 0.3 to 5.0 mm, large sawdust generated in a sawmill, and the like are also included here. The wood as a raw material may be in a dry state or contain a lot of moisture. In addition, waste paper pulp may be used. The pulp may be bleached or unbleached.

  The plant used as a Japanese paper material as an auxiliary material is good for fibers such as mulberry, mitsumata and ganpi. As other Japanese paper materials, fibers such as rice, bamboo, bamboo grass, casino ki, itobasho, kenaf, and Asa may be used. These fibers may be unnecessary fiber portions generated in the Japanese paper manufacturing process. Further, any of bleached fibers and unbleached fibers may be used. As the skin, crocodile black skin and cedar skin are suitable, but other skins may be used. These auxiliary raw material fibers and leathers are particularly effective in creating a texture of Japanese paper, especially when the interior finish material of the building is applied to the interior finishing surface such as a wall surface. The size of the fiber or skin is preferably within the range of 1 to 200 mm in maximum length. This is because if it is larger than this, the fibers and skin are too emphasized and the wall becomes unsightly, and if it is smaller than this, the design effect is also reduced. It is effective to put the texture of raw mulberry and unnecessary parts of Japanese paper material, black skin, straw, and bamboo so as to make the texture of Japanese paper even more. Among them, mixing of soot also has a design meaning, but the coated interior finish has an effect of binding raw materials by the action of fibers.

  The paste can be applied as long as it is water-soluble, but preferably a paste not containing a chemical substance, for example, a starch-based adhesive for wallpaper construction, Type 2 No. 2. Water is used to obtain an appropriate viscosity when applied to the interior finish surface of a wall or the like with a trowel. Either hard water or soft water can be used, and tap water, river water, etc. that are most readily available at the construction site can be used. .

  The mixing ratio of the main raw material, auxiliary raw material, water, and paste varies depending on the moisture content of the pulp as the main raw material. First, the ratio of the main raw material and auxiliary raw material is approximately the weight ratio with respect to the main raw material 100. It is in the range of auxiliary materials 1-5, glue 15-30, and water 30-50. Within this range, it is possible to suitably obtain a texture of Japanese paper, and a stable finish can be achieved, but even beyond this range, the texture of the Japanese paper can be secured to some extent, so that it is included in the scope of the present invention. It is.

  Next, a specific example of how to make the interior finish material for building made of each of the above-described raw materials will be described. First, about 1/3 of the main raw material pulp is placed in a bag through which water can freely pass, soaked in a container containing water and left for about one day. As the pulp, Swedish flour (trade name: ROTNEROS) is suitable. The pulp that has absorbed moisture expands about twice. Next, after removing a bag from a container containing water and removing unnecessary moisture, the swollen pulp in the bag is transferred to another container and stirred with a stirrer. And the dried fiber of Japanese mulberry, which is a Japanese paper material, is cut into pieces of about 2 mm to 5 mm and cut, and if necessary, fibers such as black leather and mulberry that are discarded when making handmade Japanese paper Then, the unnecessary part is dried and finely cut into a container containing pulp and mixed. After this preparation is complete, stir again while adding glue, and let it fit for about a day and night. As the paste, starch type adhesives for wallpaper construction, Type 2 No. 2 (trade name: Tokiwa Ecotack F ☆☆☆☆) and the like are suitable. Add water to make it easy to apply to interior finishes such as walls, and get an appropriate viscosity. In addition, it is only necessary to use glue without adding chemical substances to construct with all natural materials. As the paste, a vegetable bond formed by boiling ginnan grass can be suitably used.

A procedure for coating the interior finish material for building thus completed on the inner wall surface of the house wall will be described.
(1) Plaster board (PB) that forms the inner wall surface of the house, and undercoat material for diatomaceous earth finishing (trade name: undercoat for reve interior. High moisture absorption and release properties) is applied to the base of plywood for the purpose of improving the humidity control effect. Then dry completely. Usually it takes around 2 days. Moreover, construction is possible without this undercoating, so it is not an essential requirement.
(2) Next, if necessary, the raw fiber of sculptured mulberry cut into a string shape without applying a beater, which is a raw material for hand-made Japanese paper, is cut to about 100 mm to 200 mm, black skin, dust, scratches, etc. It mixes in the container with the finished material like. Kozo's raw fibers are white when exposed, and beige when not exposed, so they are selected according to preference. Straw, it is of, the design of contaminating the black skin and the like. This process is performed in accordance with the preference of the owner or the person in charge of the construction, and in consideration of harmony with other components in the room. The degree of mixing can be freely selected by giving priority to the design. In order to obtain a color, a colorant such as a bengara or a pigment may be mixed as necessary.
(3) The thickness of the interior finish material for building completed in the step (2) is 2 using a trowel on the interior finish surface that has undergone the step (1) or the interior finish surface that has not undergone the step (1). Apply to about 3mm. Since it takes 3 to 6 days to dry completely, even in the case of a large interior finish, the adjacent prepainted part is not dry. Because it does not appear, it is finished neatly and you can get a seamless Japanese paper texture that has never been seen before.

  The inner wall surface formed using the interior finish material made by mixing as described above is an interior finish with a texture that is seamlessly affixed with handmade Japanese paper, and is made only of natural materials. Therefore, it is kind to people and considers the environment. The building interior finishing material of the present invention is of course suitable for Japanese style, but can be suitably used for all interior finishing surfaces because it is finished in a natural color utilizing natural materials.

The figure of the corner | angular part of a Japanese-style room which has an inner wall surface formed using the building interior finishing material of this invention.
