▎ 摘　　要

NOVELTY - The lubricating oil comprises base oil, graphene-based nano-particles, antioxidants, viscosity index improvers, dispersants and antifoaming agents. Additional additive including rust inhibitors, pour point depressants, thickeners, detergents, and demulsifiers are also included in the lubricating oil. The graphene-based nano-particles contain graphene-based nano-iron, graphene-based nano-titanium, graphene-based nano-silver or graphene-based nano-copper. USE - Lubricating oil. ADVANTAGE - The lubricating oil shows excellent dispersibility and stability, good finish of antifriction effect, and good repairing performance.
