Low-viscosity wear-resistant and energy-saving lubricating oil satisfying intense driving and preparation method thereof

Abstract

The invention discloses low-viscosity wear-resistant and energy-saving lubricating oil satisfying intense driving and a preparation method thereof. The low-viscosity wear-resistant and energy-saving lubricating oil is prepared from the following components in parts by weight: 20-40 parts of polyol ester base oil, 35-55 parts of monoester base oil, 10-30 parts of ether base oil, 0.1-0.8 part of anantioxidant, 0.05-0.08 part of a wear resistance and wear reducing agent and 4-10 parts of a purification dispersant. Various ester base oil is adopted to be compounded, under the zero load conditionof the temperature of 100 DEG C, the thickness of an oil film is decreased, the viscosity of the lubricating oil is super low, the liquidity is greatly improved, the heat dispersion performance is good, the performance of high-low temperature resistance of the lubricating oil is excellent, the oil temperature is controllable, and the resistance is small; and under the high-load condition of the temperature of 150 DEG C, and the rotating speed of 106 round / s, due to the fact that the adsorption ability of the lubricating oil is high, the oil film is not prone to being squeezed out of the surface of metal, the wear resistant and wear reducing performance is excellent, and the low-viscosity wear-resistant and energy-saving lubricating oil is especially suitable for the long-distance high-rotating driving conditions and the intense driving conditions under the extreme environments such as racing.

Description

technical field [0001] The invention relates to an engine lubricating oil technology, in particular to a low-viscosity wear-resistant and energy-saving lubricating oil for intense driving and a preparation method thereof. Background technique [0002] The engine is the heart of the car. There are many metal surfaces that rub against each other in the engine. These parts move fast and the environment is poor. The working temperature can reach 400°C to 600°C. Engine lubricating oil is known as the "blood" of the car. Engine lubricating oil (that is, engine oil) penetrates between the piston and the cylinder, between the shaft and the bearing bush, and can lubricate and reduce friction for the engine, assist cooling and cooling, seal and prevent leakage, prevent rust and corrosion, shock absorption and buffering, etc. Engine oil consists of base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Addi...

AI Technical Summary

Problems solved by technology

Traditional engine lubricating oil has a relatively thick oil film under zero-load conditions at a temperature of 100°C, but the lubricating oil has high viscosity, poor fluidity, and slow heat dissipation, and the lubricating oil is not resistant to high temperatures, so the oil temperature is easy to rise and the resistance is large; while in The temperature is 150°C and the speed is 10 6 Under the high load condition of R / S, the oil film under pressure is easy to be squeezed out of the metal surface, causing wear, and the lubricating oil in the engine has a high viscosity and poor fluidity, which cannot be replenished in time, resulting in greater wear; especially in frequent intense driving, long-distance driving In the case of high-speed rotation, such as frequent driving above 4000 rotations, the requirements for oil film strength are even higher. Only when the oil film is not broken can the engine be protected. If the oil film is thin and the oil film is broken during operation, the engine wear will be greater

[0005] (2) Anti-wear and anti-friction agents are added to traditional engine lubricating oils to improve the anti-wear and anti-friction properties of lubricating oils. Increased lubrication resistance;

[0006] (3) At the same time, because the engine oil often contains sulfur, phosphorus and other elements, it will promote the corrosion and wear of some parts, and the exhaust emission is not friendly
