Description

Lubricating oil for IC engines
Technical field
The present invention relates to technical field of fine, especially a kind of lubricating oil for IC engines.
Background technology
Lubricating oil for IC engines is mainly used in motor vehicle industry, and IC engine lubricating oil can make to form profit between two rubbing surfaces Synovial membrane, change dry friction reach the purpose for reducing moving component friction, reducing abrasion into the intermolecular friction of lubricating oil.Therefore, it is interior Normal operation of the combustion engine lubricating oil for guarantee internal combustion engine, reduce energy consumption, extend the life-span, have the function that irreplaceable.
Lubricant to reduce the frictional resistance of friction pair, slow down its abrasion lubricant medium.Lubricant to friction pair also Cooling can be played, clean and prevent pollution etc..In order to improve greasy property, suitable addition can be added in some lubricants Agent.During from lubricant, motion conditions, material, surface roughness, working environment and the work bar of friction pair must be typically considered Part, and many factors such as performance of lubricant.In plant equipment, lubricant gives each need by lubricating system transmission ＆ distribution mostly The position to be lubricated.But existing lubricant viscosity is larger, coefficient of friction is higher, higher to the mechanical wear of body, therefore Need to develop the lubricant of a kind of low viscosity and low-friction coefficient, preferably play lubrication and protective effect.
The content of the invention
The technical problems to be solved by the invention are the defects of overcoming prior art, there is provided a kind of lubricating oil for IC engines.
In order to solve the above technical problems, the present invention provides a kind of lubricating oil for IC engines, it is characterized in that, including：Lubricant With base oil, oxygen-containing organic compound, friction improver, metal deactivator, rare earth nanometer particle and rare earth nanometer particle point Powder, the mass percent of the rare earth nanometer particle are 0.05%-0.15 %, the quality percentage of the oxygen-containing organic compound In the range of number is 15%-35 %, the mass percent of the rare earth nanometer particle dispersant is 20%-25%, and the friction changes The mass percent for entering agent is 2%-5 %, and the mass percent of the metal deactivator is 0.5%-1 %, and remaining is used for lubricant Base oil.
Further, between 15-30 nanometers, the rare earth nanometer particle disperses the size of the rare earth nanometer particle Agent includes polyoxyethylene alkyl ether and polyoxyethylene alkyl ether phosphate.
Further, the mass percent of polyoxyethylene alkyl ether is 12 % -13 in the rare earth nanometer particle dispersant %, remaining is polyoxyethylene alkyl ether phosphate.
Further, the oxygen-containing organic compound is that APES and polyol fatty acid ester form.
Further, the friction improver is alkyl phosphite.
Further, the metal deactivator is thiadiazole.
The beneficial effect that the present invention is reached：
By adding rare earth nanometer particle, it is effectively increased the dilution factor of lubricant while the coefficient of friction of lubricant can be reduced, increases Add the service life of internal combustion engine, reduce cost, and add rare earth nanometer particle dispersant, can more improve rare earth nanometer particle Dilution factor, and contain minor metallic element in rare earth nano, there is inoxidizability, rub resistance, corrosion resistance etc., improve The quality of lubricant.
