▎ 摘　　要

NOVELTY - The preparation method of plastic involves preprocessing 25-30 pts. wt. wollastonite fiber using liquid nitrogen as refrigerant and then oxidatively decomposing, dispersing in 55-67 pts. wt. organic solvent, adding 3-5 pts. wt. graphene-metal organic framework composite material and then electrospinning, drying the mixture, adding 40-70 pts. wt. polypropylene and 10-20 pts. wt. filler and then heating, extruding the mixture and granulating. USE - The method is useful for preparation of plastic. ADVANTAGE - The method enables preparation of plastic with excellent strength, interface strength, impact strength and mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for plastic prepared by the method.
