Abstract

The invention discloses light aging resistant ABS (acrylonitrile butadiene styrene) plastic used for inside decorations of an automobile and a preparation method thereof. The light aging resistant ABS plastic used for the inside decorations of the automobile comprises the following components in part by weight: 100 parts of ABS resin and 0.2-0.8 part of composite light stabilizer, wherein the composite light stabilizer comprises the components in part by weight as follows: 30-50 parts of C23H27N4O3, 20-40 parts of C26H50N4O2 and 5-15 parts of C10H10N4O4. The light aging resistant ABS plastic has better light aging resistance and comprehensive performance, is simple in preparation process and low in cost, can be easily processed into parts with various shapes by adopting the injection molding process, and is particularly and suitably molded into various inside decorations of the automobile.

Description

Technical field [0001] The invention relates to a plastic and a preparation method thereof, in particular to a light aging resistant ABS plastic for automobile 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 and molding. [0003] ABS resin is a graft copolymer 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 butadiene-containing graft copolymers and acrylonitrile-styrene copolymers. Among them, acrylonitrile accounts for 15~35%, butadiene accounts for 5~30%, and styrene accounts for 40~ 60%, the most common ratio of emulsion ABS is A:B:S=22:17:61, while the proportion of B in bulk ABS is often low, about 13%. [0004] ABS is a general-pu...
