Abstract

This invention relates to the technical field of dispersants, particularly to a lubricating oil dispersant. The lubricating oil dispersant is prepared from the following components in parts by weight:12-18 parts of succinimide, 2-5 parts of a sodium hydroxide solution, 2-4 parts of white carbon black, 1-2 parts of n-amyl alcohol, 2-4 parts of malonic acid and 3-5 parts of sodium sulfite. According to the lubricating oil dispersant, by modifying sodium lignosulfate, the dispersing and viscosity reducing properties of the dispersant are improved, the stability is improved and the dispersing efficiency is high; the lubricating oil dispersant has good temperature resistance, and has very good peptizing and dispersing effects on ordinary solid-state particles; by adding the modified white carbon black, the dispersing effect and dispersing speed are improved, the influence of the viscosity of lubricating oil at a low temperature is reduced, and the black oil sludge dispersion and paint filmcan be effectively adsorbed and controlled.

Description

technical field [0001] The invention relates to the technical field of dispersants, in particular to a lubricating oil dispersant. Background technique [0002] At present, people widely use the method of adding dispersant to lubricating oil, which can disperse the precursors of sludge, varnish and carbon deposits in the oil, prevent them from forming sludge, varnish and carbon deposits, prolong the oil change period, and thus prolong Service life of internal combustion engines. However, many dispersants produced in the existing market have insignificant dispersion effects and low efficiency. Contents of the invention [0003] In order to overcome the shortcomings of existing dispersants, the invention provides a lubricating oil dispersant. [0004] The technical scheme that the present invention adopts to solve the technical problem is: a kind of lubricating oil dispersant, comprises according to parts by weight: [0005] Succinimide, 12-18 parts; [0006] Sodium hydr...
