Abstract

The invention relates to conductive and flame-retardant thermoplastic resin, in particular to a polyphenyl ether resin composition with conductive and flame-retardant effects simultaneously. The composition consists of the following substances in part by weight: 20 to 100 parts of polyphenyl ether, 5 to 30 parts of conductive agent, 5 to 25 parts of flame retardant and 5 to 15 parts of compatibilizer. A nine-section temperature control double screw extrusion process is adopted in a preparation method. By adding the compatibilizer, the synergistic effect of flame retardance and conductivity of polyphenyl ether mixed resin is achieved, and the application range of the polyphenyl ether is further expanded.

Description

technical field [0001] The invention relates to a conductive and flame-retardant thermoplastic resin, in particular to a polyphenylene ether resin composition having both conductive and flame-retardant effects. Background technique [0002] Polyphenylene ether resin (referred to as PPE or PPO) is a polymer engineering plastic with a non-polar linear structure containing benzene rings in the main chain. This structure endows the material with good physical and mechanical properties, heat resistance and electrical insulation. It has low hygroscopicity, high strength, good dimensional stability, and creep resistance at high temperature is the best among all thermoplastic engineering plastics. However, pure PPE resin has a high glass transition temperature and a high melt viscosity. It needs to be processed at a high temperature of 300 ° C, and high temperature processing (330 ° C) is prone to thermal oxygen degradation, difficult processing and excessive energy consumption, and...
