Abstract

The invention discloses high-modulus ABS engineering plastic and a preparing method thereof. The high-modulus ABS engineering plastic is prepared from, by weight, 62%-72% of ABS resin, 20%-30% of styrene-maleic anhydride copolymer, 5%-10% of AS resin, 0.1%-0.3% of releasing agents and 0.4%-0.8% of antioxidants; besides, carbon fibers and silicon carbide fibers are added, and the mechanical property of the plastic is greatly improved. The high-modulus ABS engineering plastic is high in modulus, excellent in wear resistance and good in size stability, has oil resistivity, and solves the problems that ordinary ABS is prone to deformation after being stressed, and the force-bearing requirements of materials in the automobile industry cannot be met, the production cost of the plastic is lowered, and the application range is broadened.

Description

technical field [0001] The invention relates to an engineering plastic and a preparation method thereof, in particular to a high-modulus ABS engineering plastic and a preparation method thereof. Background technique [0002] Compared with general-purpose plastics, engineering plastics have higher standards in terms of mechanical properties, durability, corrosion resistance, heat resistance, etc., and are more convenient to process and can replace metal materials. Engineering plastics are widely used in electronics, automobiles, construction, office equipment, machinery, aerospace and other industries. It has become an international trend to replace steel and wood with plastic. Engineering plastics have become the fastest growing field in the plastics industry in the world today. [0003] Thermoplastic engineering plastics combine the superior properties of most plastics, such as impact resistance, low temperature resistance, wear resistance, chemical corrosion resistance, s...
