Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a tile-like architectural board used as wall material for bathrooms, etc.

[Background technology] When manufacturing tile-like architectural boards used as bathroom wall materials, etc., conventionally, decorative paper is pasted on the surface of the inorganic board, and then a clear (transparent) material is applied to the surface of the decorative paper. However, in order to improve the texture of architectural boards and make them look like tiles, it was necessary to thicken the top coat layer on the surface.
The clear had to be applied many times by hand, resulting in poor productivity.

[Purpose of the invention] The present invention was made in view of the above points, and the purpose is to provide a construction board that can improve the texture by forming a thick top coat layer with one application. It is.

[Disclosure of the invention] That is, the building board of the present invention has a base material layer 2 formed by impregnating the base material with a transparent resin and hardening it on the surface of the inorganic board 1, and also forming a hardened base material layer 2 on the surface of the base material layer 2. Transparent surface layer 3 cured with one coat of resin
The above object is achieved by pasting the resin-impregnated base material 4 impregnated with resin on the surface of the inorganic plate 1 and curing it to form a thick top coat layer 6. It is something.

The present invention will be described in detail below based on illustrated embodiments. A base material made of decorative paper or the like is impregnated with a transparent resin, and as shown in FIG. The base material layer 2 is formed on the surface of the inorganic board 1 by curing. Although the resin used here is not limited, for example, an ultraviolet curing resin can be used. Next, this base material layer 2
A top coat 5 made of an ultraviolet curing resin paint or the like is applied to the surface, and the surface is cured by irradiating ultraviolet rays from a lamp 7 to form a transparent surface layer 3. Here, as a coating machine, a spray, a flow coater, a roll, etc. can be used.

Therefore, by adhering the resin-impregnated base material 4, which is formed by impregnating the base material with resin in advance, on the inorganic board 1 and curing it, a thick base material layer 2 can be easily formed. Moreover, by forming the base material from decorative paper or the like and forming the resin from a transparent material, the pattern of the base material can be seen from the surface of the base material layer 2. Next, by applying a top coat 5 such as an ultraviolet curable resin paint to the surface of the base layer 2, the glossy surface layer 3 is formed so that even a small amount of the top coat 5 forms a uniform film on the surface. As a result, a transparent thick top coat layer 6 is formed between the base layer 2 and the surface layer 3 as shown in FIG. It can enhance the texture.

[Effects of the invention] As described above, the present invention forms a hardened base material layer by impregnating the base material with a transparent resin on the surface of the inorganic board, and also coats the surface of this base material layer with the resin once. Since a transparent surface layer is formed by curing the resin, it is possible to form a thick base layer by impregnating and curing the resin into the base material, and it is possible to form a thin surface layer with one coat of resin. It is possible to obtain architectural boards with a textured texture, and it is possible to increase productivity.Moreover, both the base material layer and the surface layer are made of transparent resin, and the base material layer and the surface layer are both transparent. By forming the material with decorative paper or the like, the pattern can be made visible from the front, making it possible to obtain architectural boards with excellent decorative properties.
