Description

DETAILED DESCRIPTION OF THE INVENTION (al) Industrial Application Field The present invention relates to a method for finishing the surfaces of buildings, roads, floors, etc. (hereinafter referred to as buildings, etc.).

(bl) Prior Art Conventionally, tile, brick, stone, etc. have been used as finishing methods for walls of buildings, etc.

However, such finishing materials are very expensive, so
Recently, spraying with inexpensive spray materials or roller construction have become more popular. This is an emulsion made of synthetic resin, etc., which is sprayed onto the wall surface and dried and hardened to form the surface. According to this method, the materials themselves are inexpensive, the construction itself is simpler than tiling, etc., and time can be saved.

(C1 Problems to be Solved by the Invention The method of using tiles or natural stones has the drawback of being extremely expensive, as described above.

In addition, the conventional spraying material construction method had the disadvantage that it had to be carried out on-site, and the work required for drying and curing the material took a long time. In other words, although it can be done in a single period compared to brickwork, etc., it still takes time. In particular, when it comes to renovation work on the interior of a store, it is natural to want to shorten the period during which the store is unable to operate as much as possible.

Furthermore, since the coating material contains a solvent, there is also the drawback that working conditions are extremely poor, especially indoors and underground. That is, there are drawbacks such as the need for a ventilation blower and the inability to work continuously for a long period of time.

Furthermore, the spraying process itself was carried out using a gun or the like, which was quite complicated and required a certain level of skill.

Therefore, in this industry, there has been a demand for a spraying method that uses inexpensive materials, is easy to construct, can be constructed in a single period, and does not require skill.

(dl Means for solving the problem) As a result of intensive research, the present inventor has completed the present invention.The main feature of the present invention is that it is a decorative board in which a coating material is applied to the surface of a sheet member. , the sheet member side is attached to a wall surface or the like with the back side.

The "coating material" in the present invention is a mud-like material,
A substance 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. Synthetic resins are often emulsion-based.
Most preferred are acrylic emulsions. Of course,
Other emulsion-based materials, epoxy-based materials, and urethane-based materials can also be used. However, the material is not limited to these, and any material that can be sprayed may be used. In short, any material that changes from a soft state to a hard state is sufficient.

The term "sheet member" includes plate-like materials such as wood, metal, and gypsum board, sheet-like materials such as paper, cloth, plastic, and metal, as well as materials such as wire mesh. Further, the shape is not limited to a rectangular shape, but may be a triangular shape, a hexagonal shape, a U-shape, an L-shape, or any other shape that can be combined and attached to the entire surface of a building or the like.

The sheet member may be one that supports the sprayed material that has been cured until the sprayed material is cured, and that it has already disappeared by the time it is attached to the wall surface. But that's fine. For example, it may be something like paper, which sometimes has been sprayed on, but which dissolves, evaporates, or elutes when adhesive is applied when pasting it to the wall. Since the synthetic resin has already hardened at the time of attachment, there is no problem even if there is no supporting sheet member.

"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 sheet member.

"Decorative board" refers to a plate-like product in which a coating material is applied to a sheet member in advance at a factory or the like.

The "back side" refers to the side that comes into contact with a wall surface, etc.

The coating material of the present invention may contain aggregate.

Here, the term "aggregate" refers to natural stone itself or fired ceramics that have been appropriately crushed.

In addition, in the case of multicolor, natural stones with different colors may be used, and ceramics may be mixed with pigments during firing. It goes without saying that a mixture of natural stone and ceramics can also be used.

In other words, if a coating material mixed with aggregate such as natural stone or ceramics is applied to the sheet member in advance at a factory, etc., and aggregates of different colors are used and sprayed so that the colors do not mix with each other, It is also possible to express the same color tone as natural stone.

Adhering refers to fixing the decorative board to the wall surface, and any adhesive may be used for this purpose, and there are no particular limitations, and ordinary adhesives such as mortar and synthetic resin may be used.

tel Example Next, a method of manufacturing a decorative board according to the present invention using a synthetic resin, particularly an acrylic emulsion, as a coating material containing aggregate will be described. If there is no aggregate, it is easier than using aggregate, and it is simpler because there is no aggregate-related process. Furthermore, the same method can be applied even when the main body of the coating material is not a synthetic resin.

The coating material is made of aggregate made of fired clay or natural stone that is crushed to show an appropriate particle size distribution, or mixed with various types of crushed materials to show an appropriate particle size distribution, and then synthesized. It is produced by mixing it into a resin (preferably a synthetic resin emulsion).

This is the gist of the coating material, which includes a thickener to improve workability, a pH adjuster to protect the container during storage (rust prevention), an antifoaming agent, etc. Good too.

Next, an example of a specific mixing ratio will be shown.

(L) Ceramics 61.60
Part (2) Acrylic emulsion ・25.20
parts (solid content 50%) (3) Thickener (hydroxymethylcellulose) 11.35 parts (41
pH11 adjuster (aqueous ammonia > 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, a thickening agent was used for ease of workability and storage.
p) L regulators, antifoaming agents, film forming aids, etc. are mixed, but
These are optional and are not essential components of the coating material.

The method for producing aggregate in the present invention is to heat clay to 1400°C.
Ceramics are fired to a certain degree and then crushed. Of course, when using natural stone, it is sufficient to simply crush it. In addition, if the clay is to be multicolored, a pigment having an appropriate color, such as iron oxide, zinc oxide, etc., is mixed with the clay and fired.

In the case of natural stone, natural stones of various tones are used.

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 crank strength, excellent weather resistance, and has an appearance very similar to natural stone.

FIG. 1 is a perspective view of a decorative board (B) according to the present invention.

In this example, a coating material (2) using ceramics of three colors (black, gray, and white) is applied to a sheet member (6) in an unmixed multicolor manner. Here, the unmixed multicolor coating means that coating materials (2) of different colors are coated so that the colors do not mix with each other. Especially in this example,
It's applied completely randomly. Because it is applied randomly and without any regularity, its appearance is almost the same as that of so-called black granite, and is extremely beautiful.

Further, in this example, since the coating material (2) is made of ceramics and synthetic resin, it is also possible to apply it a little thicker and polish the surface flat with a grinder or the like.

FIG. 2 is a partially enlarged view of FIG. 1. The black part of the finishing material (
Ia), the gray part (1b), and the white part (Ic) are composed of black particles, gray particles, and white particles, respectively.

However, each fine particle is hardly noticed by the human eye, and the colored parts (la), (Ib), and (lc) are recognized as one body, so that the appearance is similar to that of natural stone.

In this example, there are three colors, but it is possible to use not only a single color but also two colors or four or more colors.

Next, FIG. 3 shows how the coating material (2) is applied to the sheet member (6).

That is, the spray gun (7) has a plurality of tanks (3) and injection nozzles (5), and each tank (3)...
Put the materials (2) adjusted to different colors into the tank (3).
), the respective materials (2) are applied to the sheet member (6) from the respective nozzles (5) so that they do not mix.

In this way, the paints will not be mixed in the tank (3) to become one color, but will be applied in multiple colors.

Here, one embodiment of the spray gun (7) is shown in FIG.

Material A (4
a), material B (4b), and material C (4c). Those materials are entrained by compressed air and sprayed through the injection nozzle (5a),
It is injected from (5b) and (5c).

In this case, the angle of each injection nozzle (5) is adjusted so that the injection nozzles (5) are concentrated at approximately one point. However, if it is actually concentrated in one spot, the effect will be diminished because the three colors will be mixed or layered to form a single color. Therefore, the focal points of the respective injection nozzles (5) are slightly shifted from each other. However, in reality, even if the focus is exactly the same, it does not pose much of a problem because a person holds the spray gun (7) in their hand and sprays, so the distance and angle from the wall etc. will be different.

In this example, a method using a three-head type spray gun (7) is shown, but this method can be applied to any number of spray guns depending on the number of colors of the coating material (2), etc.

One of the features of this decorative board (B) is that it can have an appearance almost similar to natural stone, but this is because it can be applied with various colored coating materials as shown in Figure 1. It can only be expressed by applying a mixture of multiple colors. In other words, if you mix enough, you will end up with one color after mixing, and if you apply more than one, you will end up with the last one color. Applying while preventing this is a prerequisite for manufacturing the decorative board (B) of this example. Of course, a single color coating material (2)
It goes without saying that the application process will be easier if only the liquid is sprayed.

FIG. 5 shows how the decorative board of the present invention is attached. Attach the veneer in the same manner as you would attach a natural stone veneer. By simply pasting the material as it is without using a frame or the like, thin joints similar to those of natural stone can be created, so the traditional spraying method gives a feel that is even closer to natural stone.

This decorative board is attached to a wall surface or the like, but it may be stuck together, or it may be stuck while forming wide joints (1 ms+). It can also be incorporated and pasted into a framework.

Places other than walls can be pillars, fences, ceilings, floors, etc. This is particularly useful for ceilings, etc., which are difficult to spray using conventional methods.

([1) Effects of the Invention As described above, the decorative board used in the present invention is made by spraying a mixture of natural stone or clay-fired ceramics into a synthetic resin as an aggregate onto a sheet member in advance at a factory, etc. Therefore, it is only necessary to attach these to walls, etc. on site, which has the effect of significantly shortening the construction period and improving working conditions.

Since it is easy to construct, it does not require skilled craftsmen and has a great advantage in this respect.

Further, by applying multicolored mixed materials in a non-mixed multicolored manner, it is possible to exhibit a color tone similar to that of natural stone such as granite, resulting in an extremely aesthetically pleasing product.

Furthermore, with conventional spraying methods, the joints (usually IIIIT1 or less) that occur with natural stone cannot be created, but with this method, the joints similar to those of natural stone are created, giving the product an appearance that is more similar to natural stone. It happens.
