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: Mix 500SN60 parts of the second-class hydrogenated base oil, 35 parts of the second base oil (composite metallocene polyalpha-olefin (mPAO) and dioctyl sebacate at a mass ratio of 1:1.5), polyethylene glycol 15 parts of alcohol, 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 the mixture, the temperature of heating is 50°C, 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 after...

Abstract

Lubricating oil with high abrasion resistance is prepared in the steps of 1, heating and mixing 50-70 parts of first base oil, 30-40 parts of second base oil, 10-20 parts of polyethylene glycol, 3-5 parts of rosin modified phenolic resin, 1-3 parts of di-secondary alcohol alkyl dithiophosphate zinc, 1-4 parts of sodium benzoate, and 5-8 parts of glyceryl monostearate to obtain a mixture; 2, adding 1-4 parts of antioxygen, 1-4 parts of metal cleanser, 1-4 parts of antirust agent, and 1-4 parts of nonionic surfactant to the mixture obtained in the step 1, and conducting heating and stirring sequentially to obtain the lubricating oil. The lubricating oil is high in kinematic viscosity, small in wear scar diameter and high in 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 typical vehicle energy distribution measured by the US 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 reducing the fuel consumption of automobiles. The improvement of engine design and the improvement of lubricating oil formulation technology will directly improve the fuel economy of the car, but the cost of impr...
