<p>PURPOSE:To produce marbled SMC with excellent color by spraying glass fiber more than twice during conventional SMC producing process, thus spraying specific pattern forming material between glass fiber. CONSTITUTION:Resin mixture 2 for base SMC (sheet molding compound) including inorganic filler with refractive index of 1.5-1.6 and average grain diameter of 10-30mu, is applied on thermoplastic film carrier 3 running on an endless belt conveyor 1; glass roving 4, cut in fixed length by a roving cutters, is sprayed on it. Next, unsaturated polyester resin including a thickener is mixed with coloring filler of 50-300mu grain diameter, and pattern forming material 6 is sprayed by a sprayer 7 after being processed in desired form and size. Then, thermoplastic film carrier 3', applied with glass roving 4' cut in desired length and with SMC resin mixture 2', is laid upon it; it is defoamed and impregnated through a defoaming roll 8 to be aged for thickening.</p> |
