Problems solved by technology

[0005] At present, organic molybdenum additives have good anti-wear and anti-friction properties, but most of them have high acid value. Therefore, when these organic molybdenum additives are used in combination with other detergents, it will lead to premature acidification and deterioration of internal combustion engine lubricating oil, which is not conducive to Play their cleaning effect and anti-wear and anti-friction effect

Embodiment 1-6

[0063] Add fatty acid amide, polyisobutylene succinimide, inorganic molybdenum compound and optional distilled water, diluent oil and solvent into the reaction vessel, stir, heat up, remove moisture, and react at 120°C-160°C for 1-10 hours, Finally, the solvent is distilled off to obtain the organic molybdenum additives W-01-W-06 respectively, and the mass fraction of the molybdenum content is between 1.0% and 10.0%.

Embodiment 7-12 and comparative example 7-15

[0075] Add detergents and organic molybdenum additives to various lubricating base oils by mass percentage, mix and stir to obtain Examples 7-12 and Comparative Examples 7-15 of the lubricating oil composition. For the formulation composition of each embodiment and comparative example, see Table 4.

[0076] The detergency performance and anti-wear and anti-friction performance of these lubricating oil compositions were evaluated separately. The detergency performance of each lubricating oil composition was measured by the inclined plate coking test method, the test conditions were oil temperature 300°C, and the test time was 1h; the anti-wear and anti-friction performance of each lubricating oil composition was measured by the SRV method, the test conditions were: temperature 80°C, load 300N, stroke 1mm, test time 1 hour, frequency 50Hz, SRV method see National Energy Administration standard NB / SH / T 0847-2010. The test results are shown in Table 5.

Abstract

The invention provides a clean anti-friction composition, and a lubricating oil composition containing the clean anti-friction composition. The clean anti-friction composition comprises a clearing agent and an organic molybdenum additive, wherein the organic molybdenum additive is prepared from fatty acid amide, polyisobutylene succinimide and inorganic molybdenum compound by reaction in the presence of unessential cutback oil. The clean anti-friction composition and the lubricating oil composition have excellent clearing property and anti-wear and friction reducing properties.

Description

technical field [0001] The present invention relates to a detergent composition and a lubricating oil composition containing the detergent composition. Background technique [0002] In order to meet the requirements of environmental protection and energy saving, internal combustion engine manufacturers continue to reduce the size of the engine, increase the compression ratio, and increase the operating temperature of the engine. Therefore, the lubricating oil for internal combustion engines is required to have better cleaning and dispersing properties and anti-wear and anti-friction properties. [0003] Common detergents include sulfonates, alkyl phenates, sulfurized alkyl phenates, salicylates, etc. Common antiwear and friction reducers include molybdenum dialkyldithiophosphate, dialkyldithiomolybdenum Molybdenum carbamate, sulfur-free and phosphorus-free molybdenum ester organic molybdenum additives, etc. At present, many patents disclose the technical solution of the joi...
