Problems solved by technology

The synthesis process of polyisobutenyl succinimide ashless dispersant is complex. During the production process, hydrochloric acid gas is released, and finally the hydrochloric acid gas is absorbed by alkali. The process line is long and the pollution is large; and the structure of polyisobutylene ashless dispersant is similar to Polyolefin plastics have a very stable structure and are difficult to degrade naturally in a short time

Abstract

The invention discloses a vegetable oil modified ashless dispersant, and belongs to the technical field of lubricating oil additives. The ashless dispersant is prepared by the following method: firstly, carrying out addition polymerization reaction on vegetable oil containing unsaturated double bonds and fatty acid or anhydride containing unsaturated double bonds to obtain vegetable oil modified polymer containing carboxylic acid or anhydride; and carrying out amidation reaction on the vegetable oil modified polymer containing carboxylic acid or anhydride and organic amine to obtain a vegetable oil modified ashless dispersant. The vegetable oil modified ashless dispersant obtained by the invention has excellent dispersing performance, stable long-term high-temperature aging dispersing performance and high biodegradability, and is beneficial to environmental protection.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil additives, in particular to a vegetable oil modified ashless dispersant. Background technique [0002] During the operation of the internal combustion engine, many paint films, sludge and carbon deposits may be formed, resulting in blockage of the oil circuit and filter screen, wear of the piston, and sticking of the piston rings. Moreover, the internal combustion engine is easily corroded because the sludge contains a lot of water. The service life of the internal combustion engine is shortened. In order to solve the above problems, a method of adding a dispersant to the lubricating oil is adopted. The function of the dispersant is to disperse the precursors of sludge, varnish and carbon deposits in the oil, preventing them from forming sludge, varnish and carbon deposits, and extending Oil change intervals, thereby prolonging the service life of the internal combustion engine.
