Abstract

The invention discloses a light resistant PC (Polycarbonate) / PBT (Polybutylene Terephthalate) alloy material for an automobile and a preparation method thereof. The light resistant PC / PBT alloy material for the automobile is prepared from the components of raw materials of, in parts by mass, 50-70 parts of PC, 30-50 parts of PBT, 0.2-0.3 part of dispersing agent, 0.3-0.5 part of light stabilizer,0.3-0.5 part of ultraviolet light absorber, 0.1-0.2 part of antioxidant and 0.1-0.2 part of ester exchange inhibitor, wherein the ultraviolet light absorber is a triazine ultraviolet light absorber, and the light stabilizer is a benzotriazole light stabilizer. The light resistant PC / PBT alloy material for the automobile has a good mechanical property, good heat stability and good chemical resistance. Diversified options are supplied for the color of the product on the basis that the material is enabled to have the light resistance, the material is prepared by adopting a one-step technology, and the technology is simple and easy to operate.

Description

technical field [0001] The invention relates to a light-resistant PC / PBT alloy material for automobiles and a preparation method thereof, belonging to the field of PC / PBT alloy materials. Background technique [0002] PC / PBT alloy material takes into account the advantages of both PC (polycarbonate) and PBT (polybutylene terephthalate), and has excellent mechanical properties and processing properties. Wide range of applications, especially in recent years, the booming automobile consumer market, as well as the lightweight of automobiles, the replacement of steel with plastic in automobiles is gradually becoming a reality, which makes the usage of PC / PBT alloy materials in the automobile field increase rapidly. [0003] Under the environment of environmental protection and low cost of automobiles, coupled with the improvement of the requirements for plastic odor of automobile interior parts, more and more plastic parts begin to take off their "coats" and abandon the original...
