Engine cleaning and sealing lubricating oil

Abstract

The invention discloses an engine cleaning and sealing lubricating oil, which is characterized in that the engine cleaning and sealing lubricating oil comprises the following substances by weight: 50-80 parts of plant oil, 3-8 parts of oleic acid, 1 part of hydrophobically modified nanometer silicon oxide, 35-60 parts of fatty alcohol polyoxyethylene ether, 0.5-1.25 parts of modified polyureas, 0.4-1.34 parts of alkyl benzene synthesized calcium sulfonate, 0.9-3.4 parts of sulfurized calcium alkyl phenolate, 2-19 parts of xylene, 5-9 parts of paraffin, 4-10 parts of low molecular polyethylene wax, 20-45 parts of dichloromethane, and 25-35 parts of 10# hydrogenated machine oil. The beneficial effects reside in that: the engine lubricating oil has excellent acid neutralization capability, and excellent antiwear performance and anticorrosion performance, and compared with common lubricating oil, the antiwear performance is especially outstanding.

Description

technical field [0001] The invention relates to an engine cleaning and sealing lubricating oil. 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.

Problems solved by technology

[0003] Automobiles with engines using natural gas are more and more widely used. The temperature of the combustion chamber of this type of engine is high, and the temperature of the exhaust gas is high. The lubricating oil of the engine is easily oxidized, carbonized, and sludge is formed, which increases the carbon deposit inside the engine. , affecting the normal operation of the engine

In addition, in order to improve the lubricating performance and reduce the viscosity of lubricating oil, many lubricating oils can ensure the good work of the parts in actual work. However, under high temperature conditions, this kind of lubricating oil is volatile, resulting in Lubricants have a shorter lifespan
