Novel bio-based high-strength wear-resistant nylon composite material and preparation method thereof

The invention discloses a novel bio-based high-strength wear-resistant nylon composite material and a preparation method thereof. The composite material is prepared from the following raw materials in percentage by mass: 70-80% of nylon, 3-5% of a wear-resistant agent, 10-20% of a reinforcing agent, 0.2-0.5% of an antioxidant and 0.2-0.5% of color master batch. The preparation method mainly comprises the following steps: blending and extruding a strip-shaped blend by a double-screw extruder or an injection molding machine, cooling by circulating water, and granulating in a granulator to obtain the composite nylon particles. The wear-resistant material has the characteristics of high temperature resistance, wear resistance and good thermal decay resistance, is simple in preparation process, and effectively solves the problems of high wear rate, unstable friction coefficient, lower impact strength and the like of similar friction materials at high temperature in comparison with the conventional common method fo
