Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method for constructing a stone pseudo surface, and more specifically, it can be applied to any base such as concrete, mortar, plasterboard, etc. It is possible to create a stunning pseudo-stone surface that is indistinguishable from the surface pattern of stone at a glance, and can be used for walls, ceilings, etc. in interiors such as buildings, shops, and residences.
This relates to a new construction method that can be applied to floors and other tombstones.

(Prior Art) Conventionally, as a construction method for pseudo-surfaces made of stone such as granite, several types of crushed natural stone are placed on the base surface of concrete or mortar using white cement, white cement, etc.
It is known that by applying a mixture of water, etc., and polishing the surface after drying to make a flat surface, the crushed stone is polished out and the crushed stone is scattered on a white cement surface, giving the appearance of stone. ing. However, the stones created using this construction method clearly show the ring of polished crushed stone, and the crushed stone appears to be exposed only on the surface, so it is obvious at first glance that it is an artificial stone. Moreover, in this conventional method, everything except the polishing process was done by hand, which required considerable labor and was expensive, and the patterns that could be produced were limited.

Therefore, in order to solve the above-mentioned conventional problems, a method for manufacturing artificial stone has been proposed in Japanese Patent Application Laid-Open No. 10625/1983. This invention involves mixing colored transparent to opaque aggregate with a transparent film forming material to form a sprayed layer, and then
The aggregates having different colors and the film forming materials having different viscosities are mixed, one layer or two or more layers are sprayed onto the sprayed layer, and the surface is compacted with a roller or a trowel (first conventional method). example).

On the other hand, Japanese Patent Laid-Open No. 52-82823 proposes a method for forming a marble pattern surface on a wall surface or the like.

In this invention, a light-colored paint is applied to a smooth wall surface, etc., and dried, and then cotton is stretched and spread on the upper surface of the wall surface, etc., and stretched appropriately over the entire surface, and The four sides of the stretched cotton cotton are attached to a wall surface etc. with tape or the like, and a dark colored paint different from the light color is applied to the upper surface of the stretched cotton cotton, and the cotton cotton is removed and the paint is applied. After drying, stretch and spread another piece of cotton cotton, stretch it appropriately over the entire upper surface of the wall, etc., stick the four sides of the cotton cotton to the wall surface, etc. with tape, etc., and then apply a lighter color to the upper surface of the stretched cotton cotton. In this method, a marble pattern surface is formed on a wall surface or the like by applying a paint, removing the lint, and drying the paint (second conventional example).

(Problem to be Solved by the Invention) However, in Conventional Example 1, each sprayed layer is placed alternately by rolling it with a trowel using plastic deformation while the sprayed layer is in an unhardened state. This process creates a fluid pattern similar to that of marble, and even though it is effective as a method for manufacturing artificial stone, which is the purpose of marble, this manufacturing method is similar to the method for manufacturing marble. In this case, it was not possible to form a stone pseudo surface such as granite, which is a mixture of irregular colored mixed pieces in the stone base.

Further, the conventional example 2 is a method of forming a marble pattern surface on a wall surface etc. in the same way as the conventional example 1.
Unlike the conventional method, it uses multiple coating layers without using aggregate, and the various fluid patterns unique to marble are created by covering these coating layers with cotton wool on walls, etc., to create patterns similar to those of marble. Although this invention is effective as a manufacturing method for a specific stone such as marble, this manufacturing method does not produce a pseudo-surface of a stone such as granite, which has amorphous colored pieces mixed and integrated into the stone base. It could not be formed.

The purpose of the present invention is to provide a method for forming a pseudo-surface made of stone, such as granite, which is not made of marble having a fluid pattern as described above, but in which amorphous colored mixed pieces are mixed and integrated into a stone base. do.

(Means for Solving the Problems) The present invention employs the following configuration as a means for achieving the above object. That is, a first coating layer is formed by applying colored paint to the surface of a base material such as concrete, mortar, plasterboard, etc. using a spraying means so as to form an uneven pattern of irregular shapes such as height, height, size, etc., and after drying this, the above-mentioned coating is applied. A second coating layer is formed by applying a paint of a different color from the first coating layer to the surface of the first coating layer using a spraying means to the extent that it almost covers the coating and in a state where the uneven pattern is mixed in height and height. is dried and the third coating layer and subsequent layers are formed using the same method, and this is dried and the third coating layer and subsequent coating layers are formed using the same method.Finally, the uneven pattern portion of the top coating layer is coated with the desired stone material. A paint of approximately the same color as the ground color is filled with a coating device such as a spatula to form a filling surface layer that covers the entire surface of the top coat to make it a substantially flat surface, and then after drying, from the surface It is characterized by polishing away a certain thickness so that each coating layer is exposed in a scattered manner.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

As the base material 1 used in the present invention, any material such as concrete, mortar, plastic board, slate, brick, block, wood, plywood, etc. can be used as shown in FIGS. 1 and 2.
Note that the base material 1 is not limited to the rectangular shape shown in the drawing, but may be of an irregular shape.

The spraying means referred to in the present invention is a common method used in the painting field called spray painting or spray painting, and a spray gun is used as the equipment, and a spray gun with a relatively large diameter is suitable.

Next, as the paint used in the present invention, it is preferable to use a paint that has as high a hardness after drying as possible, such as a synthetic resin paint or a cement paint, and examples of the former include acrylic resin paint and epoxy resin paint. can.

Next, the construction process of the present invention will be explained with reference to FIGS. 3 to 8 and 9 to 13. Plasterboard is used as the base material 1, and an appropriate sealer layer is applied to the surface of the base material 1. may be provided. Then, a first coating layer 2 is formed on the surface as shown in FIG. A spray gun S is used for this formation, with an air pressure of 4 to 8 kg/cm ² and a nozzle diameter of 2 to 20 kg/cm2.
mm, preferably 3 to 8 mm, and the paint used is, for example, a black acrylic resin. At this time, the paint is not limited to black,
Further, it is preferable to use a viscosity of 40,000 to 55,000 centipoise. Spraying is carried out in accordance with the usual method, but the moving speed of the spray gun, air pressure, nozzle diameter, etc. are selected empirically depending on the desired state of pattern expression on the final finished surface. In this way, the first coating layer 2 applied to the surface of the base material 1 has a three-dimensional uneven pattern of irregular shapes such as height, height, size, etc. (FIG. 3).
At this time, the height of the coating layer 2 at the convex portion is preferably such that the first coating layer 2 is exposed on the final simulated stone surface formed on the plasterboard.

Next, after suitably drying this in a drying room or the like, a second coating layer 3 made of the same material as the first coating layer 2 is similarly formed on the surface of the first coating layer 2 by spraying means (No.
figure). The paint for this second coating layer 3 is of a different color from that of the first coating layer 2, for example, a brown one with greater brightness. The second coating layer 3 thus applied is applied high and low on the convex portions, high and low on the concave portions, or is applied in an irregular shape with a concavo-convex pattern mixed in high and low. , in which case the second coating layer 3 is the same as the first coating layer 3.
The entire surface of the coating layer 2 is thinly covered and almost hidden (FIG. 4). Next, after drying this, a third coating layer 4 and a fourth coating layer 5 are sequentially formed by the same means (FIGS. 11, 5, and 6). The paints for these third and fourth coating layers 4 and 5 are, for example, yellowish brown,
Its brightness gradually increases, resembling the color of butter.
On the uneven surface of the final layer 5 obtained in this way, apply a paint of approximately the same color as the ground color of the target stone, that is, of a brighter color than the fourth coating layer 5, using a spatula, a plastering trowel, or a trowel.
The coating is applied in a filling manner using a coating device O such as a roller to form a filling surface layer 6 covering the entire surface of the coating layer 5 (FIG. 12). The appearance of this surface layer 6 is as follows:
This is a state in which a large number of small raised convex portions 6' are scattered (FIG. 7). After further drying this, a filling surface layer 6 is formed.
The surface is polished using an electric sander D (Fig. 13). This polishing is continued until at least the convex portions of the first coating layer 2 are exposed. As a result, each coating layer 2 to 5 appears randomly scattered in irregularly shaped patterns of large and small shapes in each part, and in some cases, a pattern in which the upper coating layer surrounds the lower coating layer is displayed. (Figure 8). Next, the polished surface 7 thus formed is
It may be left as is, but a transparent finishing layer may be further formed.

(Effects of the Invention) The present invention forms multiple layers by repeating application and drying of paints of different colors on the surface of a base material using a spraying means so as to form an irregular uneven pattern of height, height, size, etc. Fill the patterned area with paint of approximately the same color as the ground color of the target stone using a coating tool such as a spatula, and form a filled surface layer that covers the entire surface of the top coating layer and makes it a substantially flat surface. Then, after drying, a certain thickness was removed from the surface by polishing so that each coating layer was exposed in a scattered manner, so that the filled surface layer became the base for the desired stone, and the multiple coating layers had the same color. Depending on the difference, it may appear as if amorphous colored pieces are mixed and integrated in the base or on the surface.In this case, if the surface layer is of the lightest color, the convex parts of the underlying coating layer will be opaque. However, it looks transparent and gives a sense of depth, giving it the appearance of natural stone. Furthermore, the coating layers 2 to 5 and the surface layer 6 are excellent in that a wide variety of stone pseudo surfaces can be formed by appropriately selecting and combining the number of coating layers or the color of the coating material.
