Abstract

The invention relates to the technical field of dispersants, and particularly relates to a high-efficient lubricating oil dispersant. The high-efficient lubricating oil dispersant is prepared from thefollowing raw materials in parts by weight: 3-8 parts of succinimide, 1-2 parts of calcium petroleum sulfonate, 1-3 parts of zinc dialkyldithiophosphate, 2-4 parts of dialkyl diphenylamine, 1-2 partsof xylene, and 2-5 parts of glycerinum. The high-efficient lubricating oil dispersant has good heat-resistant property, extremely strong solubilization on a liquid initial oxidative product of lubricating oil, a good peptizing dispersing effect on solid particles of carbon deposit, soot and the like, reduces the influence to low temperature viscosity of the lubricating oil at the same time, has small low temperature viscosity, and can effectively adsorb and control black sludge dispersion and paint films.

Description

technical field [0001] The invention relates to the technical field of dispersants, in particular to a high-efficiency lubricating oil dispersant. Background technique [0002] The dispersants currently used in lubricating oil cannot quickly and effectively disperse the lubricating oil during use, which affects the use and cannot meet the use requirements. Contents of the invention [0003] In order to overcome the shortcomings of the existing dispersants, the invention provides a high-efficiency lubricating oil dispersant. [0004] The technical solution adopted by the present invention to solve its technical problems is: a kind of high-efficiency lubricating oil dispersant, comprising according to parts by weight: [0005] Succinimide, 3-8 parts; [0006] Calcium petroleum sulfonate, 1-2 parts; [0007] Zinc dialkyldithiophosphate, 1-3 parts; [0008] Dialkyl diphenylamine, 2-4 parts; [0009] Xylene, 1-2 parts; [0010] Glycerin, 2-5 parts. [0011] According to ...
