Abstract

A building material includes a base material, a first mirror coating formed on the surface of the base material, a second mirror coating formed on the surface of the first mirror coating, wherein the first mirror coating contains a filler and a first resin material, the pencil hardness of the first mirror coating is in the range of about 3H to about 8H, the second mirror coating contains at least a second resin material, and the pencil hardness of the second mirror coating is in the range of about B to about 2H.

First claim

What is claimed is:

1. A building material comprising:
a ceramic siding board comprising cement;
a first mirror coating formed on the ceramic siding board and comprising a filler and a first resin material, the first mirror coating having a pencil hardness in a range of about 3H to about 8H; and
a second mirror coating formed on the first mirror coating and comprising a second resin material, the second mirror coating having a pencil hardness in a range of about B to about 2H.

2. The building material according to claim 1 , wherein
the second mirror coating further comprises a pigment.

3. The building material according to claim 2 , wherein
the filler comprises at least one of talc, calcium carbonate, silica, glass, quartz, aluminum, and mica.

4. The building material according to claim 3 , wherein
a content percentage of the filler in the first mirror coating is in a range of about 40 mass % to about 70 mass %.

5. The building material according to claim 1 , wherein
the filler comprises at least one of talc, calcium carbonate, silica, glass, quartz, aluminum, and mica.

6. The building material according to claim 5 , wherein
a content percentage of the filler in the first mirror coating is in a range of about 40 mass % to about 70 mass %.

7. The building material according to claim 1 , wherein
the first resin material comprises at least one of an ultraviolet-cured acrylic resin and a urethane resin.

8. The building material according to claim 7 , wherein
the second resin material comprises at least one of a fluororesin, an acrylic resin, and a urethane resin.

9. The building material according to claim 1 , wherein
the second resin material comprises at least one of a fluororesin, an acrylic resin, and a urethane resin.

10. The building material according to claim 1 , wherein
the first resin material of the first mirror coating comprises at least one of an ultraviolet-cured acrylic resin and a urethane resin,
a content percentage of the filler in the first mirror coating is in a range of about 40 mass % to about 70 mass %,
the filler comprises at least one of talc, calcium carbonate, silica, glass, quartz, aluminum, and mica,
the second mirror coating contains a pigment, and
the second resin material comprises at least one of a fluororesin, an acrylic resin, and a urethane resin.

11. The building material according to claim 10 , wherein
a protective coating is formed on a surface of the second mirror coating, and a pencil hardness of the protective coating is in the range of about B to about 2H.

12. The building material according to claim 11 , wherein
the protective coating is formed from the second resin material.

13. The building material according to claim 1 , wherein
a protective coating is formed on a surface of the second mirror coating, and a pencil hardness of the protective coating is in the range of about B to about 2H.

14. The building material according to claim 13 , wherein
the protective coating is formed from the second resin material.

15. The building material according to claim 1 , wherein
a sealer coating is formed on a surface of the ceramic siding board, and the first mirror coating is formed on a surface of the sealer coating.

16. The building material according to claim 1 , wherein
a protective coating is formed on a surface of the second mirror coating, and
a difference between the pencil hardness of the second mirror coating and a pencil hardness of the protective coating is within three grades.

17. The building material according to claim 1 , wherein
the first resin material comprises at least one of an ultraviolet-cured acrylic resin and a urethane resin which has Tg. (glass transition temperature) higher than Tg. of the second resin material.

18. The building material according to claim 1 , wherein
the first resin material comprises a urethane resin having Tg. (glass transition temperature) higher than Tg. of the second resin material.
