Low-wear scratch-resistant ABS material and preparation method thereof

Abstract

The invention relates to a low-wear scratch-resistant ABS material and a preparation method thereof. Blending of ABS with PMMA and addition of an inorganic filler, a slip agent and the like improve the resistance of the ABS to wear and scratch in order to solve the problem of poor wear resistance of the ABS. The low-wear scratch-resistant ABS material comprises, by weight, 70-90 parts of ABS resin, 10-30 parts of polymethyl methacrylate, 1-5 parts of maleic anhydride grafted styrene, 0.2-2 parts of a lubricant, 0.2-2 parts of an antioxidant, 0.5-10 parts of the slip agent, 0.5-5 parts of silicone master batches and 2-20 parts of the inorganic filler. The prepared ABS has a high pencil hardness, and has a lower wear resistance than the ordinary ABS, and the mechanical properties and the processing fluidity are not significantly less than those of the ordinary ABS.

Description

technical field [0001] The invention belongs to the technical field of plastic processing and relates to ABS, in particular to a low-wear and scratch-resistant ABS material and a preparation method thereof. Background technique [0002] At present, domestic research on scratch-resistant materials mainly focuses on polypropylene materials for automobiles, and less attention is paid to the scratch resistance of ABS. ABS is widely used in electronic appliances, instrumentation, automobiles and other fields because of its excellent surface gloss, processing flow properties, physical and mechanical properties and chemical resistance properties. At present, the methods commonly used to improve the scratch resistance of ABS surface include surface electroplating method and surface coating hardening method. These methods not only have complex procedures, high pollution and high processing costs, but also have the disadvantages of being greatly affected by product size and appearanc...
