NOVELTY - A graphene engine anti-wear repairing agent comprises 50-80 pts. wt. base material, 5-12 pts. wt. coupling agent, 6-15 pts. wt. dispersing agent, 3-9 pts. wt. base oil, and 2-8 pts. wt. alkylbenzene. USE - Graphene engine anti-wear repairing agent. ADVANTAGE - The graphene engine anti-wear repairing agent has better dispersibility in the base oil, long storage period, better suspension property, no precipitation and clumping, so that the graphene has better and stable dispersion and suspension performance in the lubricating oil. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing a graphene engine anti-wear repairing agent, which involves weighing a raw materials, adding a coupling agent and a dispersing agent to the base material, mixing uniformly, and refluxing at 85-90 degrees C for 1-2 hours to obtain a mixture-A, recovering and evaporating petroleum ether, vacuum drying the mixture-A at 100-150 degrees C for 3 hours to obtain modified graphene, adding a base oil and an alkylbenzene oil to the modified graphene, stirring for 60 minutes to obtain a mixture-B, filtering for two times to obtain the finished product (2) a method for utilization of graphene engine anti-wear repairing agent.
