Problems solved by technology

However, the main problem of existing lubricating oil additives is that they cannot solve the problem of deposits generated during the use of lubricating oils.
For example: some lubricating oils currently used produce a large amount of deposits under high temperature, high load, and long-term operating conditions, which significantly reduces the performance of the lubricating oil. If the oil is not changed in time, lubrication accidents may occur at any time

Abstract

The invention relates to a lubricating oil additive and particularly relates to an anti-wear and friction-inducing agent used in lubricating oil. The anti-wear and friction-inducing agent used in lubricating oil is prepared from sulfurized alkylphenol, alkyl salicylate, maleic anhydride, acrylic acid higher alcohol ester, polyisobutylene amine, tetrahydrofurfuryl nitrate, alkyl naphthalene and polymethacrylate according to a specific ratio. By the anti-wear and friction-inducing agent, the deposits generated during the application of the lubricating oil can be effectively prevented, the anti-wear and friction-inducing agent has excellent wear resistance, friction modification and corrosion resistance and when the anti-wear and friction-inducing agent, which is disclosed by the invention, is applied in the lubricating oil according to the amount of 200-600ppm, the fuel consumption of the motor vehicle can be decreased, the noise can be reduced, the exhaust gas emission can meet the standard and the service life of the entire motor vehicle can be prolonged.

Description

technical field [0001] The invention relates to a lubricating oil additive, in particular to an antiwear and friction reducing agent for lubricating oil. Background technique [0002] With the development of the machinery industry, machinery and equipment have higher and higher requirements for lubricating oil, but improving the quality of lubricating oil through the refining process can no longer meet the stringent requirements of high speed, high load, and high power. Additives are the essence of modern lubricating oils, and play an increasingly important role in improving machine performance. Therefore, the development and development of new multifunctional additives is one of the research priorities. However, the main problem of existing lubricating oil additives is that they cannot well solve the problem of deposits generated during the use of lubricating oil. For example: some lubricating oils currently used produce a large amount of deposits under high temperature, h...
