▎ 摘　　要

NOVELTY - Modified graphene lubricant comprises 0.3-1.5 pts. wt. valence electron modified graphene, 0.05-0.5 pts. wt. dispersant, 0.05-1 pts. wt. affinity agent and 100 pts. wt. base oil. USE - Used as modified graphene lubricant. ADVANTAGE - The modified graphene lubricant has high dispersibility and high affinity (claimed). The method is simple, environmentally-friendly, resistant to friction and suitable for industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing modified graphene lubricant comprising (i) adding valence electron modified graphene and the dispersant into the base oil, and carrying out ultrasonic vibration to obtain the mixture; and (ii) adding affinity agent to the mixture and subjecting the mixture to microwave treatment.
