Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a method for finishing walls in buildings.

(b) Conventional technology Tile, brick, stone, etc. have been used as surface finishes for walls of buildings.

This is because these materials have excellent aesthetic appearance and are highly weather resistant.

Recently, synthetic resin surface finishing materials have also been applied by spraying them onto walls or using rollers. This is because the conventional finishing materials mentioned above are expensive. There are many methods of applying this synthetic resin finishing material and many types of finishing materials, and various methods have been devised and implemented. In order to bring out the beauty of natural stone, the present inventors have also invented a method of applying pigments mixed into ceramics during firing or crushed natural stones in a plurality of colors in such a way that the colors do not mix with each other. This method can produce the same color tone as natural stone, is inexpensive, and has excellent weather resistance.

(C1 Problems that the invention aims to solve) As mentioned above, surface finishing methods using natural stones, etc. Of course, there are also domestically produced products, but they are more expensive.

In addition, the above-mentioned surface finishing method using a synthetic resin-based finishing material invented by the present inventor has the beauty of natural stone and is excellent in that respect, but the construction method using sprayed material is
This had the disadvantage that it had to be carried out on-site, and the work required for drying and curing of the coating material took a long time.

In addition, since the coating material contains a solvent, it has the disadvantage that working conditions, especially indoors and underground, are extremely difficult.

(d) Means for solving the problem The inventor of the present invention has completed the present invention as a result of intensive research.The main feature of the present invention is that a coating material is applied to a glass plate, and the coating material is applied to the glass plate. The point is that it is attached to the wall of a building with the glass side facing up.

In other words, in the wall finishing method according to the present invention, a so-called decorative laminate, in which a coating material is applied to a glass plate, is manufactured in advance in a factory, etc., and the surface is finished by pasting this decorative laminate on-site. This is the way to do it. Therefore, the construction period can be shortened, and the gloss of the glass plate provides an even more beautiful appearance.

Here, the term "coating material" refers to a thick material that hardens over time. If it is an inorganic binder, it is an inorganic binder such as cement, mortar, gypsum, or silica, and if it is an organic binder, it is a natural or synthetic resin. The synthetic resin is preferably an emulsion type, and the most preferred is an acrylic emulsion. Of course, other emulsion-based materials, epoxy-based materials, and urethane-based materials can also be used. Of course, the material is not limited to these, and any material that can be used as a spray material may be used. In short, any material that changes from a soft state to a hard state is sufficient.

"Application" means not only the usual application, but also spraying,
This concept includes troweling, etc. In short, it includes everything that applies the coating material to the glass.

The term "glass plate" refers to a so-called transparent plate-like plate, but it also includes colored glass, polished glass, patterned glass, and the like. Generally, rectangular shapes are used, but triangular, hexagonal, etc. shapes may also be used. Furthermore, from the viewpoint of strength, it is preferable to use so-called tempered glass.

"Glass" here is not limited to so-called inorganic glass,
It may be plastic, as long as it is transparent or translucent.

“Building walls” include all external walls, fences, pillars, internal walls, etc. of buildings.

In this specification, the term "aggregate" refers to natural stone itself or appropriately crushed ceramics. In addition, in the case of multi-colored materials, natural stones with different colors may be used, and ceramics may be mixed with pigments during firing. Of course, a mixture of natural stone and ceramics may also be used.

After all, the gist of the present invention is to apply a coating material to glass, prepare a decorative board in advance, and apply it to a wall surface to finish the surface. Compared to spraying wood or applying it with a trowel, spraying it on a regular wall gives it a new aesthetic appearance.

In particular, by applying coating materials of a plurality of colors to the glass simultaneously or sequentially, a flat and subtle hue is produced, and the resulting pattern is very beautiful.

(e) Examples Hereinafter, the present invention will be explained in detail based on examples shown in the drawings.

First, the method for producing the mixed material used in the present invention will be described. The mixed material is made by firing clay at high temperature or crushing natural stone itself to show an appropriate particle size distribution, or by mixing various types of crushed materials to show an appropriate particle size distribution as an aggregate, and then using this as an aggregate. It is mixed into a resin (preferably a synthetic resin emulsion).

This is the gist of the mixed material, but it is also possible to add thickeners to improve workability, pH adjusters to protect containers during storage (rust prevention), antifoaming agents, etc. good.

Next, the constituent components of one example of the mixed material used in the present invention will be shown.

(1) Ceramics 61.60
Part (2) Acrylic emulsion 25.2
0 parts (solid part 50%) (3) Thickener 11.35
Part (hydroxymethylcellulose) (4) pH adjuster (ammonia water > 0.
17 parts (5) Antifoaming agent (alcohol-based)
0.03 part (6) Coating aid (alcohol-based)
0.39 parts (7) Water 1.26
Parts are parts by weight. The film forming aid is used to lower the temperature of forming a transparent film of the emulsion.

In this example, thickener,
Although it contains pH adjusters, antifoaming agents, film forming aids, etc.
These are optional and are not essential components of the mixture.

The method for producing the aggregate is to bake clay at about 1400°C to form ceramics, which is then pulverized. In this case, the aggregate may be of a single color, but if the aggregate is of multiple colors, pigments of appropriate colors, such as iron oxide, zinc oxide, etc., may be mixed and fired. Of course, when using natural stones, it is sufficient to simply crush stones of various colors.

Next, the particle size distribution of the aggregate can be freely selected depending on the expression of the pattern, but in view of its strength and aesthetics, the following particle size distribution was adopted in this example.

Mesh distribution 3-20 30 (wt%) 20-200
40 (〃 )200-350
30 ('') When a material with such a particle size distribution is adopted, the finished material has high crack strength, excellent weather resistance, and has an appearance very similar to natural stone.

Here, an example of a decorative board (B) in which the mixed material (2) is applied to a glass plate (1) is shown in FIG.

In this example, a mixed material (2) using ceramics of three colors (black, gray, and white) is applied in a non-mixed multicolor manner. Here, the unmixed multicolor state means that mixed materials (2) of different colors are applied so that the colors do not mix with each other. For this reason, its appearance exhibits a color tone that is almost the same as that of so-called granite. Furthermore, if the mixed material (2) is applied to the glass plate (1) as in this example, and the glass side is turned upward, the gloss of the glass plate (1) and the color tone of the applied mixed material (2) can be , it has an aesthetic appearance comparable to that of natural stone.

FIG. 2 shows a method of applying the mixed material (2) to the glass plate (1).

In other words, the spray gun (4) has multiple tanks (5) and injection nozzles (6), and each tank (5) is filled with materials adjusted to different colors, so that they do not mix in the tanks (5). In this way, each material is applied to the glass plate (1) from each nozzle (6).

Here, one embodiment of the spray gun (4) is shown in FIG. Material A (?a), material B (7b), and material C (7c) are put into tanks (5a), (5b), and (5c) as mixed materials (2), respectively. These materials are entrained by compressed air and are injected from injection nozzles (6a), (6b), and (6c).

In this case, the angle of each injection nozzle (6) is adjusted so that it concentrates on approximately one point. However, if it were actually concentrated on exactly one point, the three colors would be mixed or layered to form a single color, and the effect would be lost. Therefore,
The focal points of the respective injection nozzles (6) are slightly shifted from each other. However, in reality, even if the focus is exactly aligned, it is not a big problem because people hold the spray gun (4) in their hands when spraying, and the distance and angle of the wall etc. will be off.

In this example, a method using a three-head type spray gun (4) was shown, but this method can be applied to any number of spray guns depending on the type of color of the mixed material (2), etc. - The thus formed decorative 1ffi (B) is incorporated into the sash frame (3) and attached to the wall surface (W).

The decorative board (B) in this case may be a large single piece that is attached to the entire surface of the wall (W), but it may also be divided into a plurality of pieces and attached to the wall (W). In addition, when pasting separately, please use the sash frame (3) as shown in Figure 4.
It is sufficient to simply affix it to the wall surface (W) without incorporating it into the wall surface (W), and to embed a separate joint material (8), putty, etc. in the joints of each decorative board (B).

Of course, the method of adhesion, the formation of joints, the frame, etc. are not directly related to the method of the present invention, and may simply be adhered to a wall surface or the like as is, and are not particularly limited.

(f) Effects of the Invention As described above, the method of finishing a wall surface according to the present invention is a method of applying glass temporarily coated with a mixed material to the wall surface of a building to give a surface finish. For this reason, a so-called decorative board, which is a glass plate coated with a mixed material, is manufactured in advance in a factory, etc., which not only shortens the work required on site, but also significantly improves working conditions compared to conventional methods. For this reason, it is very advantageous for shop interior remodeling work, etc., where the interior must be completed in a short period of time.

In addition, since it is used as a decorative board and has a glass surface as its surface, the luster of glass creates an unprecedented beauty.

In addition, since the surface is glass, it is difficult for dirt and other dirt to adhere to it, and it is also very easy to remove and clean, which has the extremely beneficial effect of keeping it beautiful and clean at all times. Therefore, it can be used indoors as well.

Furthermore, since it is only necessary to attach the plate-shaped body, there is no need for skilled craftsmen, unlike conventional spraying, and finishing work can be carried out relatively easily.

As described above, this is a very useful invention.
