▎ 摘　　要

NOVELTY - A multifunctional lubricating oil comprises 80-90 pts. wt. base oil, 0.06-0.1 pt. wt. modified graphene, 0.05-0.15 pt. wt. oil-soluble molybdenum amine complex, 4-10 pts. wt. viscosity index improver and 0.2-1 pt. wt. modified nano-silicon carbide particles. USE - Multifunctional lubricating oil. ADVANTAGE - The multifunctional lubricating oil has improved oxidation stability, and prevents wear at high temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the multifunctional lubricating oil, which involves preparing modified graphene, oil-soluble molybdenum amine complex, viscosity index improver and modified nano-silicon carbide particles, mixing base oil with prepared modified graphene, oil-soluble molybdenum amine complex and viscosity index improver to obtain mixed oil, heating mixed oil to 40-60 degrees C, ball milling and homogenizing by ultrasonically processing and stirring oil.
