Abstract

The invention discloses an anti-static high-gloss flame-retardant PBT / ABS composite material and a preparation method thereof. The anti-static high-gloss flame-retardant PBT / ABS composite material consists of PBT, ABS, a compatilizer, a brominated flame retardant, a coordinated flame retardant, an anti-static agent, an antioxidant and a processing aid. The anti-static high-gloss flame-retardant PBT / ABS composite material disclosed by the invention has excellent surface performance, thermal performance, chemicals resistance, coloring performance and dimensional stability while maintaining the original advantages of PBT and ABS, and also has an advantage in cost performance, and thus can be widely applied to the fields of home appliances, mechanical accessories, office supplies, electronic devices, automobile industry and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antistatic high-gloss flame-retardant PBT / ABS composite material and a preparation method thereof. Background technique [0002] ABS resin is a terpolymer composed of acrylonitrile, butadiene and styrene. Acrylonitrile provides chemical resistance and thermal stability; butadiene provides toughness, elasticity and impact resistance; and styrene imparts rigidity, gloss and processing flow. ABS has excellent dimensional stability, surface gloss, low temperature resistance, colorability and processing fluidity, and the price is relatively cheap, but its disadvantage is poor weather resistance. Polybutylene terephthalate (PBT) has the advantages of fast crystallization speed, low water absorption, excellent electrical properties and small changes with temperature and humidity, good weather resistance, excellent chemical resistance, excellent mechanical properties, excel...
