Abstract

The invention relates to the technical field of alloy materials, and discloses a wear-resistant PC / ASA alloy material and a preparation method thereof, the wear-resistant PC / ASA alloy material comprises the following components in percentage by weight: 50-70 wt % of PC resin, 5-25 wt % of ASA resin, 4-15 wt % of SAN resin, 10-20 wt % of PPO resin, 5-15 wt % of a compatilizer, 1-5 wt % of a flexibilizer, 0.1-1 wt % of an antioxidant and 0.1-2 wt % of a lubricant, the PPO resin is added into a PC / ASA alloy material, so that the wear resistance and the heat resistance of the PC / ASA alloy materialare improved, by adding of the compatilizer PS-g-MAH or HIPS-g - MAH, the compatibility of the PPO and the PC / ASA alloy material is improved, and the problem that PPO and PC / ASA are difficult to be compatible is overcome.

Description

technical field [0001] The invention relates to the technical field of alloy materials, in particular to a wear-resistant PC / ASA alloy material and a preparation method thereof. Background technique [0002] PC resin has outstanding impact resistance, transparency, flame retardant properties, dimensional stability, and high heat resistance. It is an engineering plastic with excellent comprehensive performance; however, PC resin also has obvious disadvantages, such as high cost and processing flow. Poor performance, notch sensitivity, easy cracking, acid and alkali resistance, etc., limit its application to some extent. In order to overcome these shortcomings of PC resin, it is necessary to modify PC resin and blend other polymers to prepare alloys, which is a widely used modification method. ASA resin is a graft copolymer composed of acrylate, styrene and acrylonitrile. Since the polybutadiene rubber in ABS is replaced by acrylate rubber without double bond structure, its w...
