Abstract

The invention discloses multifunctional lubricating oil which is characterized by being prepared from the following components as raw materials in parts by weight: 1-3 parts of cyano ethyoxyl phosphine sulfate polyquaternium, 0.3-0.6 part of 6-(dibutylamino)-1, 3, 5-triazole-2, 4-dithiol, 0.5-1.2 parts of lipophilic graphene nanosheets, 0.3-0.6 part of tea polyphenol chitosan nanoparticles, 0.3-0.5 part of a dispersing agent, 0.4-0.6 part of N, N-bis (2-ethoxyl)-2-aminoethanesulfonic acid, 0.1-0.2 part of thermoplastic elastomer TPEE and 60-70 parts of base oil. The invention also provides a preparation method of the multifunctional lubricating oil. The multifunctional lubricating oil is good in comprehensive performance and performance stability, excellent in anti-oxidation stability, excellent in extreme pressure performance, wear resistance and lubricating performance and diversified in function.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a multifunctional lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil is widely used in various types of automobiles and mechanical equipment because it can effectively slow down the friction and wear of mechanical parts and reduce energy loss. It is the blood of modern industry and defense industry. The performance of lubricating oil directly affects the working state and service life of mechanical parts. [0003] The existing lubricating oils are generally effective in reducing friction and wear of lubricating oil, reducing mechanical vibration noise and...
