High antiwear lubricating oil and preparation method thereof

[0010] Example 1

[0011] A wear-resistant lubricating oil, consisting of base oil, anti-wear additives, dispersants, detergents, pour point depressants, anti-corrosion antioxidants and viscosity index improvers; base oil is a mixture of 5 centistokes and HVI500, and its weight The proportion is 1:1; the anti-wear additive is nano-scale metal powder, including iron oxide powder, copper alloy powder, chromium powder, manganese powder and boron powder. The weight ratio is iron oxide powder 1, copper powder 1.5, and chromium powder 1. , Manganese powder 1 and boron powder 1.5; dispersant is polyisobutylene polybutyrimide; detergent is calcium petroleum sulfonate; pour point depressant is polymethacrylate; anticorrosion antioxidant is thion Salt; viscosity index improver is ethylene propylene copolymer; the weight percentage of various components is 2% anti-wear additive, 1% dispersant, 0.5% detergent, 0.5% pour point depressant, 0.5% anti-corrosion antioxidant, The viscosity index improver is 2%, and the base oil is 93.5%. The above-mentioned base oil, anti-wear additives, dispersants, detergents, pour point depressants, anti-corrosion antioxidants and viscosity index improvers are measured according to the weight of each component, and then mixed uniformly, heated and controlled at 45-55 ℃, stir for 80 minutes, and get the product after filtering. The product was tested by a lubricant anti-wear and extreme pressure testing machine. The results are as follows: the anti-wear effect is 1.5 times better than the existing product, the wear scar diameter is reduced by 40%; the engine noise is reduced; the same vehicle is used for the comparison test, which saves fuel The rate is 7%; the life of lubricating oil is more than doubled and the use effect is good.

[0012] Example 2

[0013] A wear-resistant lubricating oil, composed of base oil, anti-wear additives, dispersants, detergents, pour point depressants, anti-corrosion antioxidants and viscosity index improvers; base oil is a mixture of 5 centistokes, 150BS and 1HVI500, The weight ratio is 1:1:1; the anti-wear additive is nano-scale metal powder, including iron oxide powder, copper alloy powder, chromium powder, manganese powder and boron powder, and the weight ratio is iron oxide powder 1, copper powder 1.5 Chromium powder 1, manganese powder 1, and boron powder 1.5; dispersant is polyisobutylene polybutyrimide; detergent is calcium petroleum sulfonate; pour point depressant is polymethacrylate; anticorrosive and antioxidant is thion Butyl octyl salt; viscosity index improver is ethylene propylene copolymer; the weight percentage of various components is 3% anti-wear additive, 1% dispersant, 0.5% detergent, 0.5% pour point depressant, anti-corrosion and antioxidant 0.5%, viscosity index improver 2.5%, base oil 92%. The above-mentioned base oil, anti-wear additives, dispersants, detergents, pour point depressants, anti-corrosion antioxidants and viscosity index improvers are measured according to the weight of each component, and then mixed uniformly, heated and controlled at 50-60 ℃, stir for 120 minutes, and filter to obtain the product. The product was tested by a lubricant anti-wear and extreme pressure testing machine, and the results are as follows: the anti-wear effect is 2 times better than the existing product, the wear scar diameter is reduced by 50%; the engine noise is reduced; the same vehicle is used for comparison testing, which saves fuel The rate is 8%; the life of lubricating oil is more than doubled, and the use effect is good.
