NOVELTY - Graphene oxidation inhibitor comprises 15-25 wt.% N-phenyl- alpha -naphthylamine, 12-25 wt.% 2,5-mercapto thiadiazole 12C derivative, 15-30 wt.% amino borate, 15-35 wt.% high molecular weight bis-succinimide and 10 wt.% dilution oil. USE - The graphene oxidation inhibitor is useful in lubricating oil (claimed). ADVANTAGE - The inhibitor: has excellent compatibility and long service life of the machine device; improve the graphene anti-wear and anti-rust performance; and reduce attenuation of lubricating oil. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing graphene oxidation inhibitor comprising (i) heating diluent oil, (ii) adding high molecular weight bis-succinimide into the heated diluent oil and stirring at constant temperature, (iii) adding 2,5-mercaptothiadiazole 12C derivative and amino borate and stirring at constant temperature, and (iv) adding N-phenyl- alpha -naphthylamine and stirring at constant temperature to obtain final product; and (2) lubricating oil comprising graphene, graphene oxidation inhibitor and base oil.
