Problems solved by technology

[0002] Most of the electric locomotive pantograph slides are pure carbon slides. The pure carbon slides roasted according to the existing formula have good lubricating properties and have a small friction coefficient against copper wires. Although the pure carbon slides meet the standards, there are The problem of high resistance and slightly low toughness, in order to solve the problem of high resistance and slightly low toughness, and then improve the competitiveness of the product, the original formula needs to be improved, so a graphene carbon skateboard is proposed

Abstract

The invention discloses a graphene carbon sliding plate. The graphene carbon sliding plate comprises the following raw materials: graphene microchips, 325-mesh roasted fragments, 60-mesh roasted fragments and asphalt mastic, wherein the mass percent of the graphene microchips is 6-8%, the mass percent of the 325-mesh roasted fragments is 47-53%, the mass percent of the 60-mesh roasted fragments is17-19%, and the mass percent of the asphalt mastic is 24-26%. The preparation method comprises the following steps: S1, preparing the graphene microchips, the 325-mesh roasted fragments, the 60-meshroasted fragments and the asphalt mastic. According to the invention, the graphene microchips are used for replacing carbon fibers and graphite materials in an original formula, and the graphene microchips, the 325-mesh roasted fragments, the 60-mesh roasted fragments are mixed and kneaded by using the asphalt mastic, so that the finally obtained graphene carbon sliding plate has relatively low resistance and relatively strong toughness.
