▎ 摘　　要

NOVELTY - Composite nano anti-wear additive comprises graphene loaded with hydrotalcite-type compound, where hydrotalcite-type compound is nano-particle intercalated hydrotalcite; and nano-particles are nano-alumina, nanosilica, molybdenum oxide and nano titanium dioxide. USE - The additive is useful in lubricating oil (claimed). ADVANTAGE - The additive has adjustable number change, particle size and distribution of intercalation assembly body; and reduces friction, and abrasion of machine members.
