Abstract

Belonging to the technical field of high polymer materials, the invention relates to a low odor and high toughness modified PC/ABS material for vehicles and a preparation method thereof, and solves the technical problem of low impact strength of low odor PC/ABS materials in the prior art. The material is composed of 30-80% of PC, 15-65% of ABS, 1-3% of a compatilizer, 1-2% of zeolite, 1-3% of a toughening agent, and 0.1-1% of an antioxidant. The invention also provides a preparation method of the above-mentioned low odor and high toughness modified PC/ABS material for vehicles, and the prepared material not only ensures the low odor, but also guarantees the normal temperature and low temperature toughness of the material, and is especially suitable for automobile parts.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and particularly relates to a low-odor, high-toughness modified PC / ABS material for vehicles and a preparation method thereof. Background technique [0002] PC / ABS resin has excellent processability, mechanical strength and heat resistance properties, making it a widely used automotive interior material. [0003] However, in the manufacturing process of ABS resin, there are many small-molecule impurities, and the smell is unpleasant; moreover, in the preparation process of PC / ABS composite materials, various additives are often added, and these additives are often emitted to varying degrees. Unpleasant odor. Nowadays, people's requirements for life have improved a lot, and they cannot tolerate the unpleasant smell in the car. The state has also issued the "Guidelines for Air Quality Evaluation in Passenger Cars", requiring cars to reduce odor. This requires material manufacturers to ...
