Abstract

The invention discloses antistatic PC (polycarbonate) / ABS (acrylonitrile-butadiene-styrene) alloy for automotive upholsteries and a preparation method of the antistatic PC / ABS alloy. The antistatic PC / ABS alloy for automotive upholsteries is prepared from the following constituents by weight: 50 parts of ABS resin, 40-60 parts of PC resin, 0.1-1.5 parts of polytetrafluoroethylene, 1-5 parts of a coupling agent and 0.1-5 parts of a composite antistatic agent; furthermore, the coupling agent is gamma-(methacryloxy) trimethoxypropylsilane; the composite antistatic agent is prepared from the constituents by weight: 10-30 parts of stearamide propyl dimethyl-beta-hydroxyethyl quaternary ammonium nitrate, 30-60 parts of sodium allylsulfonate, 20-40 parts of N,N-bi(2-hydroxyethyl)-N-(3'-dodecyloxy-2'-hydroxypropyl) methylammonium methyl sulphate, and 5-10 parts of (3-lauramidopropyl) trimethylammonium methyl sulfate. The alloy and the preparation method disclosed by the invention are low in production cost, good in processing property, good in antistatic effect and friendly to environment. The antistatic PC / ABS alloy for automotive upholsteries disclosed by the invention is particularly suitable for being prepared into various automotive upholsteries by injection molding.

Description

technical field [0001] The invention relates to a plastic material and a preparation method thereof, in particular to an antistatic PC / ABS alloy for automotive interior parts and a preparation method thereof. Background technique [0002] ABS resin (acrylonitrile-styrene-butadiene copolymer, ABS is the acronym for Acrylonitrile Butadiene Styrene) is a thermoplastic polymer material structure with high strength, good toughness and easy processing. [0003] ABS resin is a graft copolymer of three monomers of acrylonitrile, 1,3-butadiene and styrene. Its molecular formula can be written as (C 8 h 8 ·C 4 h 6 ·C 3 h 3 N) x , but in fact it is often a mixture of graft copolymers containing butadiene and acrylonitrile-styrene copolymers, of which acrylonitrile accounts for 15-35%, butadiene accounts for 5-30%, and styrene accounts for 40- 60%, the most common ratio of emulsion method ABS is A:B:S=22:17:61, while the ratio of B in bulk method ABS is often lower, about 13%. ...
