NOVELTY - Preparing graphene oxide lubricating oil anti-wear additive comprises using a silane modifier to modify titanium dioxide to obtain a modified titanium dioxide solution, modifying graphene oxide by an amino modifier to obtain a modified graphene oxide solution, mixing the modified titanium dioxide solution and the modified graphene oxide solution, and reacting under heating to obtain a titanium dioxide/graphene oxide complex, mixing titanium dioxide/graphene oxide compound, dispersant and base oil, dispersing evenly, and filtering to obtain graphene oxide lubricating oil anti-wear additive. USE - The method is useful for preparing graphene oxide lubricating oil anti-wear additive. ADVANTAGE - The graphene oxide lubricating oil additive has a more thorough modification effect and better dispersion than the single modification comparison example, and improves the anti-wear performance of the lubricating oil.
