▎ 摘  要

NOVELTY - The preparation method of plastic involves mixing graphene, maleic anhydride, high-density polypropylene and initiator, ultrasonically dispersing the material and then placing in a twin screw extruder to obtain modified polypropylene, mixing metalized flame retardant, silane coupling agent, dispersant and anhydrous ethanol, drying and ultrasonically processing the material, volatilizing ethanol and drying to obtain modified base flame retardant, drying boron-silicon flame retardant, then adding silane coupling agent, dispersant and anhydrous ethanol, ultrasonically treating, volatilizing the ethanol and drying to obtain modified synergistic flame retardant. USE - The method is useful for preparing plastic. ADVANTAGE - The method enables simple, economical and safe preparation of plastic with excellent heat resistance, mechanical property and strength in an environmentally-friendly manner. The plastic uses easy to obtain raw material.
