Abstract

An improved lubricating oil cleaning dispersant comprises, by weight, 6-11 parts of zinc dialkyldithiophosphate, 3-8 parts of isooctyl phosphates, 4-8 parts of benzotriazole amine, 3-6 parts of chlorcosane, 1-5 parts of stearate, 5-10 part of dihydroxy methyl vinyl siloxane, 2-6 parts of calcium hydroxide, 5-9 parts of boronized polyisobutylene succinimide, 1-3 parts of neutral oil, 0.2-1 part of polyisobutylene succinimide, 2-6 parts of trimethylolpropane, 5-10 parts of pentaerythritol, 1-4 parts of calcium sulfurized alkyl phenate, 4-11 parts of zinc stearate ester, 4-8 parts of zinc dialkyldithiophosphate and 3-9 parts of hydrogen-containing silicone oil. The improved lubricating oil cleaning dispersant has the advantages that jelly and carbon deposits on components can be well cleaned, accumulation is reduced and good cleaning and oxidation resistance effects are achieved.

Description

technical field [0001] This invention relates to an improved detergent and dispersant for lubricating oils. Background technique [0002] Lubricating oil additives are one or several compounds added to lubricants to obtain new properties or improve some existing properties of lubricants. Detergent and dispersant is a surface-active substance that can absorb solid particle pollutants in the oil and suspend the pollutants on the surface of the oil to ensure that the oil participating in the lubrication cycle is clean and reduce high temperature and paint film Formation. Dispersants can disperse low-temperature sludge in the oil so that it can be filtered out in the lubricating oil circulation. The detergent and dispersants on the market are not stable in performance, cannot play a good role, and the effect is relatively single. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the problem to be solved by the present invention is to provide a ...
