Abstract

The invention discloses a modified ABS material for automobiles. The modified ABS material is prepared from, by weight, 100 to 120 parts of ABS, 20 to 30 parts of rubber, 20 to 30 parts of PC, 10 to 15 parts of hollow microspheres, 10 to 15 parts of ethylene oxide, 1 to 3 parts of a silane coupling agent, 1 to 2 parts of a light stabilizer and 1 to 2 parts of an antioxidant. The modified ABS material is good in heat resistance and light resistance and suitable for automobiles, the heat resistance and the strength of the material are improved through the hollow microspheres and the rubber respectively, and the light stability of the material is improved through the light stabilizer and the antioxidant.

Description

technical field [0001] The invention relates to a modified ABS material for automobiles, belonging to the technical field of composite materials. Background technique [0002] Due to the superior characteristics of plastics, a large number of plastics are used in automobile design, which can not only realize the lightweight design of automobile structures, but also comprehensively reflect the requirements for automobile design performance, namely lightweight, safety, anti-corrosion, shape and comfort. In addition, it is also beneficial to reduce costs and save material resources. [0003] ABS (acrylonitrile-butadiene-styrene copolymer) has many varieties, good surface treatment effect and low price. Therefore, it has always been popular in body materials and plays an important role in the production of auto parts. Although PP (polypropylene) has come from behind in the production of auto parts, the aristocratic status of ABS in high-end auto parts cannot be shaken and comp...
