Embodiment 1

[0013] An engine oil dispersant, which is composed of base oil; polyisobutylene succinimide; sulfonate; a mixture of two components of diarylamine and hindered phenol; polyisobutylene amine. The base oil is a mixture of 150BS and 400SN and 10 centistokes. The weight ratio of the three components is 1:1:1. The mixture of diarylamine and hindered phenol needs to be mixed in advance, the weight ratio of the two components is 1:1, the temperature is controlled between 40-45° C. during mixing, and the mixture is stirred for 120 minutes. The percentage by weight of each component is: 22% of base oil; 46% of polyisobutylene succinimide; 9% of sulfonate; 14% of the mixture of diarylamine and hindered phenol; 9% of polyisobutylene amine; Base oil; polyisobutylene succinimide; sulfonate; a mixture of two components of diarylamine and hindered phenol; Between 45-55°C, stir for 90 minutes. After filtering, the product of the present invention is produced.

Abstract

The invention provides a dispersing agent for engine oil. The dispersing agent is characterized by comprising the following components in percentage by weight: 46-48% polyisobutene succinimide, 9-10% of sulfonate, 14-16% of mixture of diarylamine and sterically hindered phenol, 9-11% of polyisobutenethe amine and the balance of base oil. The preparation method of the dispersing agent is simple, convenient and easy to operate, the detergent-dispersant effect of lubricating oil can be maintained for a long term, the dispersing effect on preliminary-stage products and deposits in soot, resins, glue films, carbon deposit and lubricating oil can be maintained for a long term; moreover, the dispersing agent also has thermal stability and oxidization stability and excellent low-temperature property, and can be used for maintaining the quality of lubricating oil and prolonging change cycle of lubricating oil.

Description

(1) Technical field [0001] The invention relates to a lubricating oil additive, in particular to a preparation scheme and a preparation method of an engine oil dispersant. (two) background technology: [0002] The main function of dispersants is to disperse soot, resin, film and carbon deposits, as well as early sediment products and sediments. To be effective, a dispersant should possess other properties including thermal and oxidative cavitation and good low temperature performance. If the dispersant is poorly thermally stable, it will decompose, losing linkage and suspending potentially harmful products. Poor oxidation stability can transform the dispersant molecules and form deposits themselves. This is also a major factor in the unstable quality of current engine lubricating oils. The engine lubricating oils produced by domestic manufacturers cannot achieve ideal results in the use and manufacture of various additives, and are expensive. (3) Contents of the inventi...
