The invention provides a preparation method of a copper-based graphene composite blocky material. The preparation method comprises carrying out in-situ mixing on a copper salt solution, reducing sugar, alkali and graphene as raw materials by a solution method so that graphene is uniformly dispersed in the copper solution, reducing copper into cuprous oxide by a hydrothermal reduction method, carrying out in-situ deposition on cuprous oxide particles on the graphene surface, reducing the cuprous oxide particles into copper particles by hydrogen, and carrying out discharge plasma sintering to obtain the copper-based graphene composite blocky material. The copper-based graphene composite blocky material has good graphene dispersibility, good adhesion of a copper base and a graphene reinforcing phase, high tensile strength and compressive strength, and good thermal conductivity.
