Embodiment Construction

[0005] The present invention is elaborated in detail below in conjunction with specific examples of implementation, described rapeseed oil, minus four-line oil, vulcanized cottonseed oil, and 10# hydrogenated engine oil are base oils, and mutual compatibility can ensure suitable viscosity; Octyl alcohol zinc salt and zinc di-secondary alcohol alkyl dithiophosphate are antioxidants, which can delay the oxidation of lubricating oil and affect the lubricating performance. The above-mentioned metal detergents can play a role in cleaning, acid neutralization, solubilization and The anti-corrosion effect of hypoxia can also reduce the generation of various deposits. Polyisobutylene succinimide acts as a dispersant, which can improve the uniformity of lubricating oil and improve wear resistance; polyacrylate is a pour point depressant; put rapeseed oil and four-line oil into the reaction kettle, heat Stir at 75°C for 2 hours; add vulcanized cottonseed oil, 10# hydrogenated engine oil...

Description

technical field [0001] The invention provides a lubricating oil, in particular to a lubricating oil with high resistance. Background technique [0002] During the working process of the engine, a large number of parts are adjusted and operated. These moving parts form many friction pairs, and proper lubrication is required between the friction pairs to reduce friction loss. Engine lubricating oil has the functions of lubrication, cooling, cleaning, shock absorption, sealing and antirust, and requires proper viscosity, high temperature resistance, oxidation resistance and good thermal stability. In addition, it should also have good lubricity, certain extreme pressure and clean dispersion. It is required to have good corrosion resistance, anti-foaming properties, and the ability to neutralize acidic substances. The lubricating oil of the engine is easily oxidized and carbonized to form sludge, which will increase the carbon deposit inside the engine and affect the normal o...
