▎ 摘  要

NOVELTY - Environmentally-friendly cold-resistant flame-retardant polypropylene plastic comprises 90-100 pts. wt. copolymerized polypropylene, 45-50 pts. wt. homopolymer polypropylene, 10-15 pts. wt. toughening agent, 6-10 pts. wt. graphene, 4-8 pts.wt. brucite, 4-10 pts. wt. plant fiber starch, 10-15 pts. wt. lubricant, 1-3 pts. wt. white carbon black, 8-10 pts. wt. zinc oxide and 15-20 pts. wt. styrene. USE - As polypropylene plastic. ADVANTAGE - The polypropylene plastic has excellent cold resistance and flame resistance, and degrades easily. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the polypropylene plastic comprising grinding copolymerized polypropylene, homopolymerized polypropylene, styrene, zinc oxide, white carbon, graphene and brucite in a grinder for 40-60 minutes, and sieving to obtain a mixed raw material 1, adding plant fiber starch, toughening agent and lubricant to the mixed raw material 1, adding to the mixing kettle and mixing for 50-80 minutes to obtain a mixed raw material 2, and feeding the mixed raw material 2 into the screw extruder to obtain a extruded material.
