▎ 摘  要

NOVELTY - A high strength composite material comprises 90-120 pts. wt. polyphenylene sulfide resin, 20-40 pts. wt. organosilicon grafted polyphenylene sulfide resin, 30-50 pts. wt. PTFE resin, 20-40 pts. wt. acrylonitrile-styrene-acrylate terpolymer, 30-50 pts. wt. copper-plated carbon fiber, 20-40 pts. wt. modified glass fiber, 5-10 pts. wt. nano-tungsten disulfide powder, 10-20 pts. wt. graphene, 0.1-0.5 pt. wt. antioxidant 1076 (octadecyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate)), and 0.1-0.5 pt. wt. 2-hydroxy-4-n-octyloxybenzophenone. USE - The high strength composite material is useful for replacing metal material used for automobile components, industrial equipment, and military national defense applications, in chemical industry, and for aerospace applications. ADVANTAGE - The high strength composite material has excellent hardness, toughness, wear resistance, high-temperature resistance, corrosion resistance, and thermal conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the high strength composite material, which involves: uniformly mixing polyphenylene sulfide resin and PTFE resin, heating to a molten state, stirring, cooling and crushing into particles; uniformly mixing the particles with organosilicon grafted polyphenylene sulfide resin, acrylonitrile-styrene-acrylate terpolymer, antioxidant 1076 (octadecyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate)) and 2-hydroxy-4-n-octyloxybenzophenone to obtain mixture (A); uniformly mixing copper-plated carbon fiber, modified glass fiber, nano-tungsten disulfide powder and graphene to obtain mixture (B); and adding mixture (A) to an extruder from the main feeding port, adding mixture (B) to the extruder from the side feeding port, melt extruding, and granulating.
