Document Type and Number:
Japanese Patent JP2586783
Kind Code:
B2
Abstract:
PURPOSE: To produce an artificial marble excellent in pollution resistance without occurrence of a crack or a fracture in molding, without phase separation in the polymerization reaction or without deformation in demolding.
CONSTITUTION: With 100 pts.wt. unsaturated polyester resin containing a radical- polymerizable monomer, 10 to 28 pts.wt. epoxy resin, 100 to 1000 pts.wt. inorganic filler, 10 to 500 pts.wt. particles and 3 to 13 pts.wt. α,β-unsaturated dibasic acid and/or acid anhydride thereof are blended and the resultant mixture is cured. As the curing processes, the first stage curing is carried out at a relatively low temperature of 40 to 90°C and, after demolding, the second stage curing is carried out at a relatively high temperature of 120 to 180°C.
