The invention discloses a preparation method of a C/Cu composite pantograph slide plate. The preparation method comprises the following steps of: (1) carrying out hydrophilization, surface roughening, sensitization and activation treatment on the surface of graphite powder; (2) placing the graphite powder in a copper-containing plating solution for chemical plating, and carrying out vacuum drying after cleaning to obtain copper-plated graphite powder; (3) carrying out hydrogen reduction treatment on the copper-plated graphite powder; and (4) uniformly mixing the copper-plated graphite powder with electrolytic copper powder, sintering by adopting a vacuum hot pressing method, and taking out after the temperature is reduced to obtain the C/Cu composite pantograph slide plate. The invention further discloses the C/Cu composite pantograph slide plate prepared by the method. The preparation method disclosed by the invention is simple in process, short in production period and low in energy consumption, and the prepared C/Cu composite pantograph slide plate has excellent wear resistance and small friction factor.
