▎ 摘　　要

NOVELTY - A graphene nano zerovalent-silicon-manganese-copper-based lubricant comprises base oil, graphene nanoparticles, antioxidant, viscosity index improver, dispersant, antifoaming agent, and other additives. The other additive is rust inhibitor, pour point depressant, tackifier, detergent, and demulsifier. The graphene nanoparticles contain graphene nano zerovalent silicon, graphene nano zerovalent manganese, and graphene nano zerovalent copper. USE - Graphene nano zerovalent-silicon-manganese-copper-based lubricant (claimed). ADVANTAGE - The graphene nano zerovalent-silicon-manganese-copper-based lubricant has excellent dispersibility, stability, tribological property, and self-healing property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene nano zerovalent-silicon-manganese-copper-based lubricant, which involves adding raw materials, mixing and ultrasonic processing.
