Abstract

The invention provides a high-strength ABS composite material and a preparation process thereof. The ABS composite material is prepared from ABS master batches, carbon fibers, graphene, a metal reinforcing agent, a compatilizer, an antioxidant, zinc stearate, stearic acid and a coupling agent. The preparation process comprises the following steps: 1) preparing each base material; 2) performing ABS master batch treatment; 3) treating graphene by stearic acid; 4) performing mixing to prepare base material particles; 5) carrying out melt blending and injection molding on the base material particles, the metal reinforcing agent, the compatilizer, the antioxidant, the zinc stearate and the coupling agent. The process is simple, the continuity is strong, the production efficiency is high, and the high-strength ABS composite material prepared by the method has the advantages of higher impact strength and surface hardness, high toughness, high strength, light weight, high tear resistance, corrosion resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-strength ABS composite material and a preparation process thereof. Background technique [0002] ABS plastic is a terpolymer of three monomers of acrylonitrile A, butadiene B, and styrene S. The relative content of the three monomers can be changed arbitrarily to make various resins. ABS plastic has the common properties of three components. A makes it chemically resistant, heat-resistant, and has a certain surface hardness. performance. Therefore, ABS plastic is a "tough, hard and rigid" material with easy-to-obtain raw materials, good comprehensive performance, low price and wide application. ABS plastics are widely used in machinery, electrical, textile, automobile, aircraft, ship and other manufacturing industries and chemical industry. [0003] At the same time, ABS has excellent mechanical properties, its impact strength is good, and it can b...
