NOVELTY - The preparation of graphene composite material for pantograph carbon sliding plate involves using foam graphene as a substrate, carrying out vacuum pumping treatment, impregnating foam graphene with asphalt under high pressure, carrying out oxygen barrier carbonization of foam graphene after impregnation, subjecting carbonized foam graphene to cutting and polishing to the required size of the pantograph. USE - Preparation of graphene composite material for pantograph carbon sliding plate (claimed). ADVANTAGE - The method enables preparation of graphene composite material with high mechanical strength and impact resistance.
