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 base material; a first mirror coating formed on the base material and containing 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 containing at least 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 contains a pigment.

3 . The building material according to claim 2 ,
wherein the filler includes 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 includes 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 includes one of an ultraviolet-cured acrylic resin and a urethane resin.

8 . The building material according to claim 7 ,
wherein the second resin material includes 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 includes 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 includes 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 includes 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 includes 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 the base material includes one of a ceramic siding board, an ALC board, a metal siding board, and a resin board.

16 . The building material according to claim 1 ,
wherein a sealer coating is formed on a surface of the base material, and the first mirror coating is formed on a surface of the sealer coating.

17 . 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.
