The invention discloses an illumination aging-resistant ABS plastic and a preparation method thereof. The illumination aging-resistant ABS plastic is prepared from the following components in parts by weight: 100 parts of ABS resin and 0.3-0.5 part of composite light stabilizer; and the composite light stabilizer is prepared from the following components in parts by weight: 40-60 parts of 2-[2-hydroxy-4-(2,2,6,6-tetramethylpiperidine)-4-oxy]carbonylmethoxyphenyl]-2H-benzotriazole and 40-60 parts of N,N'-bis(2,2,6,6-tetramethyl-4-piperidyl)-N,N'-dialdehyde hexamethylenediamine. The illumination aging-resistant ABS plastic is excellent in illumination aging resistance, and the preparation process is simple, the product cost is low, and the comprehensive properties of the product are excellent. The illumination aging-resistant ABS plastic can be easily processed into parts in various shapes by use of an injection molding process, and especially can be molded into various automobile interior trim parts.
Description
technical field [0001] The invention relates to a plastic and a preparation method thereof, in particular to an anti-light aging ABS plastic 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 40-30%. 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%. [0004] ABS is a general-purp...
