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
The present invention relates to a kind of lubricating oil additive, relate in particular to a kind of multi-effect lubricating oil additive and preparation method.
Background technology
The subject matter that the existing lubricant additive exists is well to solve the settling problem that lubricating oil in use produces.For example: some lubricating oil that use produce a large amount of settlings under high temperature, high loading, long period operational condition at present, and the use properties of lubricating oil is obviously descended, if untimely changing oil can cause the generation of lubricated accident at any time.
Along with Development in Machine Industry, machinery equipment is more and more higher to the requirement of lubricating oil, but from refining process improve that quality of lubrication oil can not satisfy at a high speed, high loading, harsh requirement such as high-power.Additive is the marrow of modern lubricating oil, is bringing into play more and more important effect to improving machine performance, therefore, and to the exploitation of novel multifunctional additive with to develop a kind of be one of research emphasis.
Summary of the invention
The present invention is directed to above problem and proposed a kind of multi-effect lubricating oil additive, it can effectively prevent the settling that lubricating oil in use produces, and has good resistance to abrasion, friction improver and rust-preventing characteristic simultaneously, is a kind of lubricating grease multiple function additive.
