▎ 摘  要

NOVELTY - Lubricating oil additive comprises carbon point and rare earth metal complex. The carbon point and the rare earth metal complex are connected in the way of chemical bond. USE - The lubricating oil is useful in field of automobile, railway, aviation, ship, military equipment, electric power, metallurgy, cement, oil field, paper making and coal. ADVANTAGE - The lubricating oil: connects the lubricating oil additive with the rare earth metal complex by chemical bonds through carbon dots, which can fully exert its synergistic effect; has excellent anti-wear and anti-friction effect; is economical; has environmental protection, simple process, and is suitable for mass production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing lubricating oil additive comprising reacting carbon dots with a rare earth metal complex to obtain the lubricating oil additive; a lubricating oil comprising the lubricating oil additive and a base oil. The mass percentage content of lubricating oil additives in the lubricating oil is 0.0025-0.3%; and preparing lubricating oil comprising mixing the lubricating oil additive with the base oil to obtain the lubricating oil.
