▎ 摘　　要

NOVELTY - A graphene-based lubricating oil comprises 100 parts mass base oil, 0.05-1 part mass paper-type graphene microspheres and 2-14 parts mass additives. The paper-type graphene microspheres are wrinkled from a single layer of graphene sheets. The microspheres are set with diameter of 500 nm-5 m, density of 0.2-0.4 g/cm3, and specific surface area of less than 200 m2/g. The carbon to oxygen ratio is 20-60. USE - Graphene-based lubricating oil (claimed). ADVANTAGE - The graphene-based lubricating oil has excellent mechanical properties and elasticity, impact resistance, high stability, high dispersibility and excellent wear resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-based lubricating oil, which involves (1) adding paper-type graphene microspheres, dispersant, binding agent, viscosity modifier, anti-foam agent and preservatives to the base oil, stirring evenly, and (2) dispersing the obtained mixture, defoaming and ultrasonically processing the obtained product.
