SMC COMPOSITION CAPABLE OF IMPROVING THE SMOOTHNESS AND THE FLATNESS OF A SHEET MOLDING COMPOUND PANEL, A MANUFACTURING METHOD THEREOF, A SMC SHEET AND A PANEL MANUFACTURED BY USING THE SAME

摘要

PURPOSE: An SMC composition is provided to increase the surface glossiness of a SMC sheet and a panel, and to prevent the shrinkage of the SMC panel or banding phenomenon in advance.;CONSTITUTION: An SMC composition comprises an unsaturated polyester resin, glycol, an unsaturated dibasic acid, a low contraction agent, a hardener, a filler, etc. The manufacturing method of SMC sheet using a compound including the SMC composition comprises: a step of spreading the compound(14) on PE films(10,26), and attaching the glass fiber(22) on the surface of the PE films; a step of manufacturing a SMC sheet(32) by compressing the PE film; a step of loading the SMC sheet in a packing box, and packing by a coating film; and a step of aging the packed material.;COPYRIGHT KIPO 2012
