Abstract

The invention discloses a multi-effect lubricating oil additive which comprises the following components in parts by weight: 10-25 parts of metal cleaner, 8-18 parts of ash-less dispersant, 8-15 parts of amine ash-less antioxidant, 10-25 parts of anti-wear agent and 5-16 parts of viscosity improvement agent. The invention also discloses a preparation method of the multi-effect lubricating oil additive. The multi-effect lubricating oil additive can effectively prevent lubricating oil from generating deposits in a use process, has good wear resistance and rust protection, is an excellent friction modifier, and can ensure that the oil consumption of a motor vehicle is low, the noise is reduced, the exhaust emission reaches the standard, and the service life of the whole vehicle is prolonged.

Description

technical field [0001] The invention relates to a lubricating oil additive, in particular to a multi-effect lubricating oil additive and a preparation method. Background technique [0002] The main problem existing in the existing lubricating oil additives is that they cannot well solve the problem of deposits generated during the use of the lubricating oil. 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. [0003] 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 essen...
