▎ 摘　　要

NOVELTY - Preparing graphene lubricating additive comprises mixing graphene oxide, aluminum oxide and the first dispersion liquid to form a complex in which the graphene oxide is supported on the aluminum oxide, and obtaining the first mixed liquid in which the complex is dispersed, mixing the inorganic metal powder and the second dispersion liquid to obtain the second mixed liquid, and mixing the first mixed liquid and the second mixed liquid so that the inorganic metal powder is supported on the complex body. USE - The method is useful for preparing graphene lubricating additive. ADVANTAGE - The graphene lubricating additive has very excellent anti-wear and anti-friction properties.
