Summary:The invention discloses a preparation process of an oxygen-free copper-based high-strength composite material, which comprises the following steps: uniformly mixing chromium powder, nano titanium carbide and graphene/copper composite powder according to a formula ratio to obtain a mixture, putting the mixture in a mold, and carrying out spark plasma sintering under protective gas at the sintering temperature of 850-1000 DEG C, the applied pressure of 20-50 MPa and the sintering heat preservation time of 5-7 m i n to obtain the oxygen-free copper-based high-strength composite material. According to the oxygen-free copper-based high-strength composite material and the preparation method thereof, the graphene/copper composite powder is adopted, based on the fact that graphene has an extremely high specific surface area, the relation between graphene and a matrix is increased, more interfaces are generated, meanwhile, the graphene can effectively hinder contact among particles of a body material, and the oxygen-f
