Graphene lubricating oil for vehicles and preparation method thereof

Abstract

The invention discloses a graphene lubricating oil for vehicles and a preparation method thereof. The graphene lubricating oil is prepared from the following components in parts by weight: 20-30 partsof modified graphene, 50-70 parts of base oil, 10-20 parts of nano ions, 4-6 parts of a dispersing agent, 14-20 parts of a viscosity improver, 10-16 parts of a preservative, 6-10 parts of an anti-foaming agent and 8-12 parts of aluminum hydroxide ceramic powder. According to the graphene lubricating oil for vehicles and the preparation method thereof, by adding the preservative, prolonging the service life of parts, adding the dispersing agent, improving the suspension stability and adding the aluminum oxide ceramic powder, the quality of an oil product is improved, and the wear resistance and the wear reduction performance of the oil product are also improved; the lubricating property of the automobile lubricating oil is greatly improved, the lubricating requirement of an automobile in acold and severe environment is met, the preparation process is simple, the prepared lubricating oil has an obvious lubricating effect, the abrasion of parts is reduced, and the automobile lubricatingoil can be used in the cold environment.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a graphene lubricating oil for vehicles and a preparation method thereof. Background technique [0002] Lubricating oil is divided into two categories: industrial lubricating oil and automotive lubricating oil. Among them, automotive lubricating oil includes engine oil, water tank and cooling system oil, automatic gearbox oil, gear oil, brake and clutch system oil, etc. Lubricating oil It is generally composed of base oil and additives. For engine oil, the base oil usually accounts for about 90%, and the remaining additives account for 10%. The quality of the base oil is crucial to the performance of the lubricating oil, which provides the most basic Lubricating, cooling, anti-oxidation, anti-corrosion and other properties, so in order to improve the remaining properties of the lubricating oil, additives that can improve its overall performance are added to the lubricatin...

AI Technical Summary

Problems solved by technology

[0003] Lubricating oil for vehicles is mainly divided into mineral lubricating oil, synthetic lubricating oil, semi-synthetic lubricating oil, etc. It can establish an oil film between the piston and the cylinder, between the main shaft and the bearing bush, to prevent excessive wear of the parts, and it can also Bring the heat back to the oil tank and then dissipate it into the air to help the water tank cool the engine. Through the flow of lubricating oil, it can bring the carbides, sludge, and worn metal particles on the engine parts back to the oil tank, and use the flow to wash the parts on the working surface. Lubricating oil can form a sealing ring between the piston ring and the piston to reduce the leakage of gas and the entry of external pollutants, but most of them are ordinary lubricating oils on the market. With the rapid development of the automobile industry, the performance of lubricating oil Higher requirements are put forward; in harsh weather environments such as cold, the fluidity of ordinary lubricating oil is still not high, and a good oil film cannot be formed, and the lubrication effect is not good, which increases the wear of the parts and shortens the use of the parts life
