Abstract

The invention discloses engine lubricating oil. The engine lubricating oil is prepared from the following components in parts by weight: 10-15 parts of fluorine-containing phenyl modified hyperbranched polysiloxane HPSi-NH2, 8-12 parts of 1,3-adamantane dicarbonyl chloride / hydroxyl fluorosilicone oil polycondensate, 1-3 parts of antioxidant, 1-3 parts of viscosity improver, 3-5 parts of surface modified titanium dioxide quantum dot / nano chromium oxide compound and 65-85 parts of base oil. The invention also discloses a preparation method of the engine lubricating oil. The engine lubricating oil is better in comprehensive performance, better in lubricating effect, higher in chemical stability and thermal oxidation stability, wider in use temperature range and more excellent in wear resistance and corrosion resistance, and can directly save oil and improve the output power of an engine.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to an engine lubricating oil and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy and the improvement of people's living standards, automobiles have gradually become popular and become one of the main tools for modern people's transportation. Its power, economy, stability and environmental protection have attracted widespread attention. The engine is the device that provides power for the car, the heart of the car, and the key factor that determines the stability and service life of the car. And 30% of the energy consumption in the engine is consumed in motion friction, therefore, it is necessary to use engine lubricating oil. Engine lubricating oil with excellent comprehensive performance is very important to improve automobile power, economy, stability and environmental protection. [0003] Engine lubricatin...
