The graphene lubricating grease as a compound is prepared from the following components in parts by weight: 100 parts of lubricating grease and 0.001 to 0.1 part of surface-modified graphene powder, wherein the surface-modified graphene powder is prepared by using a solvent method; a surface-modified coupling agent accounts for 0.5wt%-2wt% of the graphene powder; the graphene is dispersed in a solvent containing the coupling agent at the temperature of 30 to 60 DEG C and then is filtered and dried, thereby obtaining the modified graphene powder. As the method is used, the defects of poor mixing uniformity, low utilization rate, high addition quantity and the like in the prior art are overcome. By utilizing the characteristics of the graphene which is ultrathin, ultrahard and superlubricant as well as in corrosion resistance and high-temperature resistance, based on the higher molecular modification of the surface of the graphene and the high-dispersion mixing of the graphene with a lubricating agent, the graphene-based lubricating product is prepared.
