Abstract

The invention discloses an automotive weatherproof ASA material, and a preparation method and an application thereof. The material comprises the following components, by weight: 20-50% of ASA resin, 25-40% of AS resin, 20-40% of ABS resin, 0-10% of ABS high-rubber powder, 0.1-0.5% of an antioxidant, 0.1-0.5% of an auxiliary antioxidant 168, 0.2-0.5% of an ultraviolet absorber UV-770, 0.2-0.5% of a light stabilizer, and 0.05-0.2% of a dispersant. The ASA material prepared with the method provided by the invention has the advantages of low cost, good weather resistance, good processability, and the like. The ASA material provided by the invention can pass the low temperature -40 DEG C and high temperature 90 DEG C thermo-cycling test of FAW-Volkswagen with still qualified mechanical performances.

Description

technical field [0001] The invention discloses a preparation method of an ASA material with high and low temperature resistance, high toughness, high fluidity and spray-free. In particular, it relates to a weather-resistant ASA material for vehicles and a preparation method and application thereof. Background technique [0002] ASA resin is a terpolymer of acrylonitrile, styrene, and acrylate, and is a substitute for ABS resin. Compared with ABS, due to the introduction of acrylate rubber without double bonds instead of butadiene rubber, the weather resistance has been substantially improved, which is about 10 times higher than that of ABS. Other mechanical properties, processing properties, electrical insulation, Chemical resistance is similar to ABS. In addition, ASA has good colorability, and because the resin itself has excellent weather resistance, it can be dyed into various bright colors without fading. Products processed with ASA resin do not need surface protecti...
