Abstract

The invention discloses a PC / ABS (polycarbonate / acrylonitrile-butadiene-styrene) composite material and a preparation method thereof. The PC / ABS composite material comprises the following raw materials in parts by weight: 40-80 parts of PC; 10-40 parts of ABS; 4-20 parts of UPE (Unplasticized Polyethylene); 0.1-2 parts of a silane coupling agent; 3-12 parts of LLDPE (Linear Low Density Polyethylene); 0.1-2 parts of a foaming agent; 0.5-2 parts of a lubricant; 0.1-1.5 parts of metal powder and 0.1-1.5 parts of pearl powder; 0.1-1 part of an antibacterial agent; 0.1-1 part of a dispersant; and 0.2-0.4 parts of an antioxidant. The composite material has high thermal stability, high transparency, excellent dispersing performance and good weather resistance, has colorful metal / pearlescent texture, can replace electroplating or paint spraying of plastic products, achieves a spraying-free effect of the products, and meets the performance and appearance quality requirements of products such as electric appliance engineering materials, automobile engineering materials and building plastic products.

Description

technical field [0001] The invention belongs to the technical field of modified plastics, and in particular relates to an antibacterial PC / ABS composite material which is wear-resistant and weather-resistant and has colorful metal effects and a preparation method thereof. Background technique [0002] PC / ABS composite material inherits the high heat resistance, high impact and high dimensional stability of PC and the high flow and low internal stress of ABS. It is a kind of composite material with excellent comprehensive performance.
