Summary of the invention
The objective of the invention is to solve the problem that exists in the fast technology, provide a kind of engine and machinery equipment are had significantly wear-resistant, anti-attrition, repairing effect, mechanical inside is not had corrosive nature, the lubricating oil anti-wear additive that cost is low.
Technical scheme of the present invention
A kind of additive for wear resistance of lubricating oil is characterized in that: by base oil, dispersion agent, nanometre metal powder, pour point depressant, viscosity index improver are formed; Nanometre metal powder comprises cupric oxide powder, magnesium powder, manganese powder and chromium powder.Dispersion agent is polyisobutene Double Tops imides; Pour point depressant is a polymethacrylate; Viscosity index improver is ethylene propylene copolymer (OCP); The weight percent of various components is: dispersion agent 1-4%; Pour point depressant 2-5%; Viscosity index improver 1-3%; Nanometre metal powder 4.5-28%, surplus is a base oil.
A kind of above-mentioned additive for wear resistance of lubricating oil is characterized in that: base oil is 150BS, 10 centistokes, any one combination of components in the 150BS in the 5 centistoke base oils and other two kinds of base oils, and the weight quota ratio of each component is 1: 1.
A kind of above-mentioned additive for wear resistance of lubricating oil is characterized in that: the weight quota of each component of nanometre metal powder is than being cupric oxide powder 2～10%; Magnesium powder 1.5～10%; Manganese powder 0.5～4%; Chromium powder 0.5～4%.
A kind of above-mentioned additive for wear resistance of lubricating oil is characterized in that: the Nano metal powder mean particle size is 25～35nm.
A kind of manufacture method of above-mentioned additive for wear resistance of lubricating oil, it is characterized in that: base oil, dispersion agent, nanometre metal powder, pour point depressant, viscosity index improver are mixed, heat and controlled temperature in 50～60 ℃, stirred 180～240 minutes, promptly get product after the filtration.
Advantage of the present invention: this manufacture method is simple and practical, and the additive cost that makes is low, and oil soluble is good, all can play good anti-wear effect to each class lubricating oil, and good wear and repairing effect do not have corrosive nature to mechanical inside.
