Problems solved by technology

However, ABS itself is prone to yellowing, mainly caused by butadiene, because there are unreacted double bonds, the weather resistance is greatly affected, and it turns yellow and brittle over time, which affects the appearance of the product and also affects the mechanical properties of the product. performance

Abstract

The invention provides a high weather-resistant spray-free metal-imitating ABS composite material. The ABS composite material comprises, by weight, 80 to 95 parts of ABS, 5 to 20 parts of modified ABS, 1 to 10 parts of spray-free metal-imitating master batches, 0 5 to 2 parts of a silicane coupling agent, 1 to 5 parts of a crosslinking aid, 0.5 to 2 parts of a dispersant and 1 to 5 parts of a toughening agent. The modified ABS is a copolymer of ABS, 4-[2-(3, 5-dihydroxyphenyl)vinyl]-1, 2-benzenediol and diacrolein pentaerythritol. The spray-free metal-imitating master batches are modified ABS-coated pearlescent metallic pigments.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a metal-like ABS composite material with high weather resistance and spray-free coating. Background technique [0002] ABS resin is an acrylonitrile-butadiene-styrene copolymer, because of its good comprehensive properties, high impact strength, chemical stability, and good electrical properties. ABS resin has a complex two-phase structure. Rubber is the dispersed phase, SAN is the continuous phase as the matrix resin, and the rubber is dispersed in the matrix resin in granular form. Due to the existence of rubber particles, ABS resin has more excellent properties, especially impact resistance. ABS resin has impact resistance, high rigidity, oil resistance, low temperature resistance, chemical resistance, excellent mechanical strength and electrical properties; easy to process, good dimensional stability and surface gloss, easy to paint and color, and can also be processed Sec...
