NOVELTY - High strength engineering plastic comprises 20-30 pts. wt. high density polyethylene, 10-20 pts. wt. butyral resin, 4-12 pts. wt. polyurethane, 4-10 pts. wt. ethylene-maleic anhydride copolymer, 7-14 pts. wt. coconut shell fiber powder, 2-6 pts. wt. calcium sulfate, 3-9 pts. wt. nano-zirconia, 1-3 pts. wt. graphene, 1-3 pts. wt. nano-titanium dioxide, 4-10 pts. wt. silicon micropowder. USE - High strength engineering plastic. ADVANTAGE - The high strength engineering plastic is simple, obtained engineering has excellent strength, has good compression resistance and flame retardant performance, widely used in the automobile industry, and is commonly used for manufacturing automobile parts, ome appliance industry, and building decoration industry. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a high-strength engineering plastic, which involves: (A) mixing high-density polyethylene, butyral resin, polyurethane, ethylene-maleic anhydride copolymer and then adding to the mixer for mixing, where mixing temperature is 140-180 degrees C for 10-25 minutes to obtain a mixture A; (B) adding mixture A to nano-zirconia, nano-titanium dioxide, silicon micro-powder, after mixing, adding mixture to a high-speed mixer to obtain a mixture B; and (C) adding coconut shell fiber powder, calcium sulfate, and graphene to the mixture B, stirring well at normal temperature, and then putting mixture into a twin-screw extruder for extrusion to obtain an engineering plastic.
