Abstract

The invention discloses a PC / ABS alloy possessing metal luster and its preparation method. The PC / ABS alloy possessing metal luster comprises the following ingredients by weight percentage: 30-80% of polycarbonate, 10-60% of acrylonitrile-styrene-butadiene copolymer; 5-20% of flexibilizer; 0.2-2% of coupling agent; 0.2-1% of anti-oxidant; 0.5-2% of processing auxiliary agent and 0.5-3% of pearl powder. According to the invention, the pearl powder replaces of metal powder, the fire hazard and blast are not easy to happen during the preparation process, so that the potential safety hazard can be eliminated. The pearl powder has small influence on the material performance; the material keeps good mechanical property. The material has metal luster which is a substitution of metal material in certain extent, thereby the production cost of the product can be effectively reduced.

Description

[technical field] [0001] The invention relates to the field of polymer materials, in particular to a PC / ABS alloy with metallic luster and a preparation method thereof. [Background technique] [0002] The lightweight of the car is to reduce the curb weight of the car as much as possible under the premise of ensuring the strength and safety performance of the car, so as to improve the power of the car, reduce fuel consumption, and reduce exhaust pollution. Most of a car's weight comes from its metal components. In order to reduce the weight of automobiles, replacing metal with plastics has become a trend in the development of the automobile industry. [0003] At present, the interior parts of foreign automobiles have basically been plasticized, and the application range of plastics in automobiles is expanding from interior parts to exterior parts, body parts and structural parts. The key development direction in the future is to develop reinforced plastic composite material...
