Description

COATING, COATING MATERIAL LAYER, AND LAMINATED STRUCTURE}

The present invention relates to a novel coating material, a coating material layer, and a laminated (coating) structure. The present invention is mainly applicable to buildings, civil engineering structures and the like.

Background Art [0002] Conventionally, natural stone is widely used as a surface cosmetic material in buildings and wall surfaces of civil engineering structures. In such a material, the deep aesthetics peculiar to a natural product can be expressed. However, regarding natural stone, disadvantages, such as an expensive point, a difficult point of processing, and a heavy weight point, are mentioned. In particular, it is difficult to process and has a heavy weight, which may adversely affect the workability and safety when applied to a wall surface or the like.

Under such a background, various methods have recently been proposed for obtaining a finish of natural stone by ceramics. For example, Japanese Patent Laid-Open No. 11-130980 (Patent Document 1) describes a composition containing an aggregate having a particle size of 0.05 to 5 mm and an acrylic resin emulsion containing a silicon atom in a resin skeleton. Japanese Laid-Open Patent Publication No. 2000-15999 (Patent Document 2) describes a ceramic material in which a colored aggregate having a uniform particle size is mixed and dispersed in a colorless transparent binder within a range of 10 to 1000 µm. However, since such a ceramic material has aggregate as a main component, the specific gravity of a material is comparatively large. In addition, since the required amount during coating is also relatively high, there is a limit in terms of weight reduction.

On the other hand, Japanese Patent Laid-Open No. 5-237444 (Patent Document 3), Japanese Patent Laid-Open No. 2005-238138 (Patent Document 4) and the like form a natural stone pattern by spray coating a plurality of colored paints of different colors. A method is disclosed. This method is advantageous in terms of weight reduction compared to the methods of Patent Documents 1 and 2 described above.

However, in the methods of Patent Documents 3 and 4, since a plurality of paints are required, the painting work is complicated, and it is also difficult to reproduce a predetermined pattern. Moreover, the shape formed tends to give an artificial impression, and the depth unique to natural stone is hard to be obtained. Moreover, the pattern surface obtained by this method may cause the temperature rise by sunlight or the like.

In addition, the base material 1 may be flat or may have unevenness.

On the surface of the base material 1, the colored undercoat material layer 2 is formed. The colored undercoat material layer 2 can be formed by coating the colored undercoat material with respect to the base material 1. What is necessary is just to coat this coloring undercoat material uniformly on the whole base material.

What is necessary is just to coat these coloring materials simultaneously or in order. When painting several types of coloring materials at the same time, a multihead type spray coating machine etc. can be used as a coating mechanism. The coating amount of a coloring material becomes like this. Preferably it is 0.01-0.8 kg / m <^2> .
