NOVELTY - Graphene lubricating oil comprises base oil, modified graphene additive and an additive in a weight ratio of 1:0.05-0.2:0.05-0.15, where the additive is composed of antioxidant, friction moderator, viscosity index improver, emulsifier and dispersant in a weight ratio of 1:0.5-1:1:0.3-0.8:0.7-1.5, and the modified graphene additive is prepared by mixing graphene with dimethylformamide, sodium alkylbenzenesulfonate and gum arabic, dispersing ultrasonically, then mixing with aminobenzoic acid, and stirring. USE - Used as graphene lubricating oil. ADVANTAGE - The graphene lubricating oil: has excellent abrasion resistance and anti-oxidation performance; and avoids use of fluoride-modified lubricating oil, and thus it is environmentally friendly. DETAILED DESCRIPTION - Graphene lubricating oil comprises base oil, modified graphene additive and an additive in a weight ratio of 1:0.05-0.2:0.05-0.15. The modified graphene additive is prepared by mixing graphene with dimethylformamide, sodium alkylbenzenesulfonate and gum arabic, dispersing ultrasonically at a power of 800-1000 W for 30-50 minutes to obtain dispersed graphene solution, then mixing the dispersed graphene solution with aminobenzoic acid, and stirring for 45-60 minutes at a stirring speed of 300-500 revolutions/minute. The additive is composed of antioxidant, friction moderator, viscosity index improver, emulsifier and dispersant in a weight ratio of 1:0.5-1:1:0.3-0.8:0.7-1.5.
