Abstract

A non-halogen low-smoke flame-retarding polycarbonate/acrylonitrile butadiene-styrene resin is proportionally prepared from polycarbonate/acrylonitrile butadiene-styrene resin, non-halogen primary flame retardant, Si-type secondary flame retardant, efficient compatibilier, anti-impact modifier and machining assistant.

Description

technical field [0001] The invention relates to a flame-retardant polycarbonate / acrylonitrile-butadiene-styrene resin, in particular to a halogen-free low-smoke flame-retardant polycarbonate / acrylonitrile-butadiene-styrene resin and a preparation method thereof. Background technique [0002] Polycarbonate / acrylonitrile-butadiene-styrene resin (PC / ABS) alloy is a heterogeneous multiphase system, which combines the excellent properties of both ABS and PC. On the one hand, it can improve the heat resistance of ABS, Impact resistance and tensile properties, instead of ABS for high-performance areas; on the other hand, it can reduce the cost and melt viscosity of PC, improve fluidity, improve its processing performance, and reduce the sensitivity of product internal stress and impact strength to product thickness It is a polymer alloy with comprehensive properties, replacing PC for the processing of thin-walled and long-process products. Numerous patent documents have reported t...
