Abstract

A polycarbonate resin composition provided by the present invention comprises: polycarbonate resin (A); impact-resistant polystyrene resin (B); and unsaturated dicarboxylic anhydride copolymer (C); wherein, The unsaturated dicarboxylic anhydride copolymer (C) is formed by the copolymerization of unsaturated dicarboxylic anhydride monomer and styrene monomer, its solution viscosity is below 1.9cps, and the content of unsaturated dicarboxylic anhydride monomer is 10 ~60% by weight; the above composition can improve the fluidity, impact strength and elongation properties of the resin composition.

Description

technical field [0001] The present invention relates to a polycarbonate resin composition, which is composed of polycarbonate resin, impact-resistant polystyrene resin and unsaturated dicarboxylic anhydride copolymer, which can improve the fluidity of the resin composition, Impact strength and elongation properties. Background technique [0002] Polycarbonate resin has the advantages of good heat resistance and impact resistance, and is mostly used in automobile parts, home appliance parts, OA machine parts, etc. In recent years, the processing conditions of polycarbonate resin have become more and more stringent , For example: thin meat processing or the reduction of cycle time, therefore, polycarbonate resin must find better processing characteristics as a coping strategy. [0003] In the prior art of improving the fluidity of polycarbonate-based resins during molding, polycarbonate-based resins and acrylonitrile-diene-styrene-based resins (hereinafter referred to as ABS ...
