Patent ID: 7427642

Claim:
A plate-like artificial marble having a thickness of more than 1 mm prepared by mixing 100 to 250 parts by weight of an inorganic filler, 0.1 to 10 parts by weight of a cross-linkable additive, 0.1 to 5 parts by weight of a reaction initiator and 0 to 100 parts by weight of an additive selected from an antifoamer, a reaction modifier, a coupling agent, a UV absorber, a pigment, a color granule and a wetting agent with 100 parts by weight of a liquid syrup made from defective products of industrial acrylate based sheets having a refractive index of 1.47 to 1.53 wherein the acrylate has an average molecular weight of 30,000 to 150,000, so as to form a marble plate; and wherein the liquid syrup is prepared by mixing and dissolving 60 to 99 parts by weight of methylmethacrylate monomer and 1 to 40 parts by weight of the defective products of industrial acrylate based sheets.
