This invention discloses a functional plastic based on modified graphene and its preparation method, belonging to the field of polymer materials technology. 70-85 parts of polypropylene resin, 15-20 parts of polycarbonate resin, 5-8 parts of modified graphene, 5-10 parts of lubricant, 3-6 parts of flame retardant, 2-5 parts of toughening agent, 1-3 parts of additive, and 0.05-0.25 parts of initiator are added to a mixer and mixed uniformly. The mixture is then melted and extruded through a twin-screw extruder to obtain functional plastic. The additive in this invention provides the plastic with excellent antioxidant properties, making it difficult to oxidize even at high temperatures. Due to its chemical interaction with both the base resin and the modified graphene, it can provide stable antioxidant effects for a long time. The modified graphene is highly dispersed in the plastic formulation, thus significantly improving the impact resistance, wear resistance, and flame retardancy of the functional plastic. The additive and modified graphene work synergistically, along with the other additives, to improve the overall performance of the plastic.
