Abstract

The invention relates to polyester resin film plastic and method for preparing same, wherein the plastic is the mixture of unsaturated polyester resin, polyphenylacetylene, polymethyl methacryate, thickening agent, gasket material and fiber glass, the thickening agent is prepared from peroxybenzoic acid resin, black paste and talcum powder through agitating.

Description

technical field [0001] The invention belongs to plastic materials, in particular to a polyester resin molding compound and a manufacturing method thereof. Background technique [0002] The known polyester resin molding compound (DMC), because of its light weight, high specific strength, easy molding and good corrosion resistance, is widely used in machinery and electrical products as insulating structural parts and housing materials. However, the unsaturated polyester resin, which is the main component of the above-mentioned known polyester resin molding compound, is in a state of polymerization and shrinkage during the thermoplastic process, which causes ripples on the surface of the product and affects its flatness and smoothness. Contents of the invention [0003] The invention aims to solve the technical problems of the known polyester resin molding compound in terms of flatness and smoothness, and discloses a polyester resin molding compound and a manufacturing method...
