The present invention provides a graphene copper pantograph pan material for high-speed trains and a preparation method thereof, and the pan uses graphene as a reinforcing material, copper and iron as base materials, coke powder and graphite fiber as self-lubricating wear-resistant materials, and titanium, tungsten and molybdenum as additives. After being uniformly mixed, all the components are directly formed by hot pressing. The pantograph pan prepared by the present invention has the advantages of favorable electrical conductivity, wear resistance, impact resistance, ablation resistance and the like, and has little wear to overhead lines. The pan not only has simple preparation process, but also has much better performance than the conventional carbon pans and metal impregnated pans. The pan material is not only suitable for pantograph pans for high-speed trains such as high-speed rails and bullet trains, but also suitable for electric contact materials for low-speed trains such as subways.
