  • Patent number: 4966794
    Abstract: Disclosed is a process for fabricating an artificial stone molded body by mixing an inorganic filler such as alumina with a resin binder and polymerizing and curing the mixture. A high-viscosity syrup formed by preliminarily polymerizing a polyol polyallyl carbonate with an ethylenically saturated monomer is used as the resin binder and is mixed with the inorganic filler. According to this process, the polymerization is completed in a short time and the internal stress in the molded body is moderated. The molded body fabricated according to this process is excellent in Barcol hardness, pencil hardness, taper abrasion, Sharpy impact strength, flexural strength, heat resistance and chemical resistance.
