  • Patent number: 9422427
    Abstract: An artificial marble chip of the present invention comprises curable resin, metal fiber and/or inorganic fiber, and inorganic filler. The metal fiber and/or inorganic fiber preferably have an average length of about 1 to about 6 mm and an average particle diameter of about 10 to about 15 ?m. An artificial marble according to the present invention is produced by using the artificial marble chip, curable resin matrix, and inorganic filler as main components. The curable resin is preferably selected from acrylic resin, unsaturated polyester resin, epoxy resin, or a copolymer thereof. The artificial marble according to the present invention is produced by the steps of: producing an artificial marble composition by mixing the artificial marble chip, the inorganic filler, and other additives into the curable resin matrix; and curing the composition at about 25 to about 180° C. The invention can also include the step of defoaming the composition prior to curing.
