▎ 摘　　要

NOVELTY - A composite polypropylene material comprises 60-100 pts. wt. polypropylene resin, 0.1-15 pts. wt. modified white graphene, 0.1-10 pts. wt. white oil, and 0.1-20 pts. wt. dispersant, where modified white graphene is polymer-coated white graphene and polymer is styrene or acrylic ester monomer. USE - Composite polypropylene material. ADVANTAGE - The polypropylene material has excellent low-temperature impact resistance and good toughness and wear resistance, is easy to color, has transparent color, and does not need to add auxiliary reinforcement. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the polypropylene material comprising mixing raw materials and extruding.
