▎ 摘　　要

NOVELTY - A polypropylene composition comprises 60-85 pts. wt. polypropylene resin, 5-10 pts. wt. high-density polyethylene resin, 5-20 pts. wt. dendritic toughening agent, 1-5 pts. wt. graphene, and 3-5 pts. wt. surface modifier. USE - Polypropylene composition. ADVANTAGE - The polypropylene composition changes the material surface tension, can effectively reduce material surface chemical corrosion, and has good impact resistance, improved chemical resistance and material flexural modulus, and chemicals nano-barrier effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of polypropylene composition comprising adding high-speed mixer with raw materials, mixing, adding to double-screw extruder, extrusion melting at 170-220 degrees C and at speed of 350-450 revolutions/minute, and granulating.
