PURPOSE:To obtain grain-like artificial marble having excellent smoothness, luster, etc., by blending an epoxy resin with a curing agent (promoter), a specific filler and a patterning material and curing and molding by cast molding or compression molding using a mold. CONSTITUTION:(A) An epoxy resin (e.g. bisphenol A glycidyl ether) is blended with (B) a curing agent (e.g. phthalic anhydride), (C) a curing promoter (e.g. benzyldimethylamine), (D) one or more fillers selected from silica, aluminum hydroxide and glass powder and (E) a patterning material composed of a granular solid resin. Then the blend is cured and molded by cast molding or compression molding using a mold to give grain-like artificial marble. The component E is obtained by blending a resin such as epoxy resin or unsaturated polyester resin with a filler such as silica or glass, curing and grinding into 0.1-3mm particle diameter. |
