NOVELTY - Metal nano-graphene composite self-repairing additive comprises 25-40 pts. mass metal nano-composite powder, 3-10 pts. mass dispersant, 0.5-7 pts. mass stabilizer, 0.5-2 pts. mass antioxidant, 1-5 pts. mass performance regulator, 3-20 pts. mass auxiliary additive, 80-100 pts. mass dispersion medium and 0.1-0.5 pt. mass graphene. USE - Metal nano-graphene composite self-repairing additive. ADVANTAGE - The metal nano-graphene composite self-repairing additive has high hardness, and greatly reduces the friction coefficient and improves extreme-pressure value of lubricant, thus, achieving energy saving and emission reduction effects, and prolonging oil change period. DETAILED DESCRIPTION - Metal nano-graphene composite self-repairing additive comprises 25-40 pts. mass metal nano-composite powder, 3-10 pts. mass dispersant, 0.5-7 pts. mass stabilizer, 0.5-2 pts. mass antioxidant, 1-5 pts. mass performance regulator, 3-20 pts. mass auxiliary additive, 80-100 pts. mass dispersion medium and 0.1-0.5 pt. mass graphene. It is prepared by adding dispersant into dispersion medium, adding metal nano-composite powder and stabilizer, dispersing to obtain metal nano-composite powder dispersion, adding antioxidant and performance modifier, grinding in grinding machine, adding graphene, and uniformly mixing to obtain the product.
