The invention discloses a high-strength wear-resistant plastic material. The high-strength wear-resistant plastic material is characterized by being prepared from the following components in parts byweight: 65-85 parts of anthrone-based polycondensate, 15-25 parts of silicon / boron / fluorine-containing copolymer, 5-10 parts of carbon nanometer fiber, 1-3 parts of impact modifier, and 1-3 parts of toughening agent. A preparation method of the high-strength wear-resistant plastic material comprises the following steps: S1, putting the components into a high-speed mixer according to a ratio, and uniformly mixing to obtain a mixture; S2, pouring the mixture obtained in step S1 into a twin-screw extruder for extrusion molding; S3, cooling the extruded product obtained in step S2 with circulatingwater of 8-12 DEG C, and pelletizing and packaging to obtain a finished plastic material product. The high-strength wear-resistant plastic material disclosed by the invention has the characteristicsof excellent anti-aging performance, good oil resistance, wear resistance, oxidation resistance, good flame retardant effect and high strength.
