  • Colored material coated transparent chip for artificial stone, method of preparing same, and artificial stone including same
    Patent number: 8475890
    Abstract: The present invention provides transparent chips with natural metal-like texture by coating silica-containing transparent chips with colored material, such as a metal powder, in a transparent resin as a base resin. The present invention also provides artificial stone with natural metal-like texture and patterns by mixing the colored material coated transparent chips and inorganic filler with a matrix resin. The artificial stone of the present invention can be prepared by mixing about 4 to about 24 parts by weight of inorganic filler and about 0.1 to about 5.0 parts by weight of the colored material coated transparent chips, per about 1 part by weight of the matrix resin. The colored material coated transparent chips can have a specific gravity of about 2.0 to about 2.65, while the matrix resin can have a specific gravity of about 2.2 to about 2.
