Embodiment 1

[0019] The lubricating oil adopted in the invention has good weather resistance, and the problem of lubricating property decline will not occur after long-term use. Its preparation method is:

[0020] Step 1: Combine 60 parts of the second-class hydrogenated base oil 500SN, 35 parts of the second base oil (composite metallocene polyα-olefin (mPAO) and dioctyl sebacate at a mass ratio of 1:1.5), polyethylene glycol 15 parts of diol, 5 parts of rosin modified phenolic resin, 2 parts of di-secondary alcohol alkyl zinc dithiophosphate, 3 parts of sodium benzoate, 5 parts of monoglyceride stearate, stir after heating to obtain a mixture, the temperature of heating is 50°C, and the stirring time is 3 hours;

[0021] Step 2: Add 3 parts of antioxidant dinonyl diphenylamine to the mixture obtained in step 1, 3 parts of metal cleaner high alkali sulfur alkylphenate calcium (T122), and rust inhibitor benzotriazole (T706) 3 parts, nonionic surfactant sorbitol monooleate 2 parts, stir a...

Abstract

A lubricating oil with good anti-wear performance, the lubricating oil is prepared by the following method: Step 1: 50-70 parts of the first base oil, 30-40 parts of the second base oil, 10 parts of polyethylene glycol ~20 parts, 3~5 parts of rosin modified phenolic resin, 1~3 parts of di-secondary alcohol alkyl dithiophosphate zinc, 1~4 parts of sodium benzoate, 5~8 parts of monoglyceride stearate, stir after heating , to obtain the mixture; Step 2: Add 1 to 4 parts of antioxidant, 1 to 4 parts of metal cleaner, 1 to 4 parts of antirust agent, and 1 to 4 parts of nonionic surfactant to the mixture obtained in step 1. 4 parts, stirred after heating up to obtain lubricating oil. The lubricating oil of the invention has good kinematic viscosity, small wear scar diameter and good lubricating performance.

Description

technical field [0001] The invention relates to a lubricating oil with good anti-wear performance, which belongs to the technical field of lubricating oil. Background technique [0002] In the automotive industry, tribological behavior is a major cause of mechanical failure and energy consumption in vehicles. According to the energy distribution of typical vehicles measured by the U.S. Environmental Protection Agency (EPA), 62% of the fuel energy is consumed due to unavoidable heat dissipation, and the remaining 38% of the effective mechanical energy is consumed in various components of the vehicle. The friction loss of the components accounts for 10.5%. Facts have proved that: Reducing the energy loss caused by the friction of engine components is an important factor in achieving a reduction in vehicle fuel consumption. The improvement of engine design and the improvement of lubricating oil formulation technology will directly improve the fuel economy of vehicles, but the...
