Abstract

The invention discloses a yellowing-resistant PC / ABS (polycarbonate-acrylonitrile-butadiene-styrene) alloy for automobile interior ornaments and a preparation method thereof. The yellowing-resistant PC / ABS alloy for automobile interior ornaments comprises the following components in parts by weight: 200 parts of ABS resin, 40-60 parts of PC resin, 0.5-1.5 parts of polytetrafluoroethylene and 0.1-5 parts of composite yellowing-resistant agent. The composite yellowing-resistant agent is composed of the following components in parts by weight: 10-30 parts of 2-(2'-hydroxy-3',5'-diamylphenyl)-benzotriazole, 30-60 parts of titanium white, 20-40 parts of butylated hydroxytoluene and 5-15 parts of 2-hydroxy-4-n-octyloxydiphenyl ketone. The alloy has the advantages of low production cost, favorable working properties, favorable yellowing-resistant effect and environment friendliness. The yellowing-resistant PC / ABS alloy for automobile interior ornaments is especially suitable for preparing various automobile interior ornaments by injection molding.

Description

technical field [0001] The invention relates to a plastic material and a preparation method thereof, in particular to a yellowing-resistant 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, abou...
