NOVELTY - A high dispersion modified graphene lubricating oil comprises 0.3-1.5 pt. wt. de-valence electron modified graphene, 0.05-0.5 pt. wt. dispersant and 100 pt. wt. base oil. USE - High dispersion modified graphene lubricating oil (claimed). ADVANTAGE - The service life time period of mechanical components is extended, and the fuel is saved. The emission is reduced and the lubricating oil is environmentally-friendly and is obtained with strong lubricity and anti-friction property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of high dispersion modified graphene lubricating oil, which involves adding denaturated electron modified graphene and dispersant into base oil, and ultrasonically vibrating to obtain the mixture, subjecting the mixture to microwave treatment to obtain modified graphene lubricating oil with good dispersing performance, to obtain high dispersion modified graphene lubricating oil.
