▎ 摘  要

NOVELTY - Graphene nanometer micro lubricating grease comprises 5-40 wt.% thickener, 1-20 wt.% modified graphene, 0.5-8 wt.% other additives and remaining amount of base oil, where the modified graphene used is graphene modified by carbon nitride nanotubes and the other additives comprises antioxidant, preservative, viscosity improver and/or rust inhibitor. USE - As graphene nanometer micro lubricating grease. ADVANTAGE - The lubricating grease has high temperature resistant, high product stability, excellent chemical stability and abrasion resistance, and is highly dispersible, simple and easy to control. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the graphene nanometer micro lubricating grease involving heating and dissolving the base oil and thickener, and mixing to obtain a first mixed liquid, adding modified graphene to first mixed liquid, and mixing to obtain a second mixed liquid, adding other additives to the second mixed liquid, cooling the mixture and post-processing to obtain the product.
