Abstract

The present invention is less-glossy easy-to-machine thermoplastic resin composition and its extruding processing method. The thermoplastic resin composition is the mixture of PVC 10-80 weight portions, ABS resin 0-88 weight portions, ABS grafted copolymer 1-35 weight portions, styrene-acrylonitrile-ethylene copolymer 0-55 weight portions, acrylonitrile gel 1-10 weight portions and fluoroelastomer as machining assistant 0-5 weight portions, and has total rubber content of 5-30 wt%. The thermoplastic resin composition has excellent extruding formation performance, oil resistance and antishock performance as well as high rigidity, heat resistance, weather resistance, fireproof performance and economic performance.

Description

technical field [0001] The invention relates to a low-gloss easy-to-process thermoplastic resin composition and an extrusion processing method, in particular to an ABS-PVC alloy resin composition, which can be used in related fields such as sealing strips, pipes, plates, and flame-retardant shells. Background technique [0002] Due to the superior overall performance of low-gloss thermoplastic polymers, especially ABS / PVC alloy materials, there are many units engaged in research in this area, and there are many public reports. Disclose a kind of PVC / ABS alloy material of low ABS content as CN1191232A, adopt the ABS resin of high rubber phase (butadiene) content to modify PVC resin; Its manufacturing method; there are also flame-retardant grade ABS / PVC injection molding alloy (publication number is CN 1107487A) and the like. The characteristic of this type of technology is that the production and processing technology is relatively complicated. Either the stabilizer, additiv...
