Abstract

The invention discloses a high-glossiness and wear-resistant PC-ABS alloy material and a preparation method thereof. The high-glossiness and wear-resistant PC-ABS alloy material comprises, by weight, 40-90 parts of alloy resin, 10-60 parts of ABS resin, 1-10 parts of PA resin, 1-5 parts of wear-resisting agent, 1-5 parts of compatibilizer, 0.1-1 part of antioxidant and 0.1-1 part of lubricating agent. The high-glossiness and wear-resistant PC-ABS alloy material and the preparation method thereof have the advantages that the wear-resisting agent is added, high-pressure inert gas is fed during the molten state of the PA resin, and accordingly the compatibility of PC and PA is promoted, the PC-ABS system is allowed to have better flowability, and high glossiness is achieved; meanwhile, the dispersing of the wear-resisting agent in the PC-ABS system is promoted, and the wear resistance of the PC-ABS alloy material is further increased.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-gloss and wear-resistant PC-ABS alloy material and a preparation method thereof. Background technique [0002] PC-ABS alloy material is a modified plastic made by mixing polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS). This modified plastic has better performance than pure PC and ABS. Well, on the one hand, it can improve the heat resistance and tensile strength of ABS, on the other hand, it can reduce the melt viscosity of PC, improve the processing performance, so that it can be used to form large-area and complex products, and at the same time reduce the internal stress of the product. Improve low temperature impact resistance. Therefore, PC-ABS alloy materials have been widely used in the fields of communication electronics, household appliances and automobile industries, especially high-gloss PC-ABS alloy materials, which are widely u...
