NOVELTY - High performance graphene composite grease comprises 100 pts. wt. lubricating base oil, 1-5 pts. wt. dispersant, 5-15 pts. wt. thickening agent, 10-30 pts. wt. anti-wear agent, 0.1-3 pts. wt. graphene mixture, 10-40 pts. wt. calcium lignosulfonate and 1-5 pts. wt. nanoparticles, where graphene mixture is graphene oxide, ammonia graphene, sulfonated graphene. USE - Used as high performance graphene composite grease. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of high-performance graphene composite grease comprising (i) adding lubricating base oil, calcium lignosulfonate and graphene into the reaction kettle, stirring at 50-100 degrees C for 1-2 hours, and then reacting at 70-80 degrees C for 1-5 hours, (ii) adding dispersant, thickening agent and antiwear agent into the reaction kettle, stirring at 70-120 degrees C for 1-3 hours, and then adding nano-silica, heating at 150-200 degrees C, refining, and continuing heating for 30-100 minutes, and (iii) cooling the reaction kettle to 20-40 degrees C and grinding and carrying out homogenization to obtain final product.
