Composite additive for engine oil

Abstract

The invention provides a composite additive for engine oil. The composite additive is composed of base oil, an anti-oxidant, a detergent additive, a dispersing agent, an extreme-pressure additive, rhenium-molybdenum alloy metal powder, polymethacrylate, a methyl benzoyl triazole derivative and sulfurized dipolybutene, wherein the anti-oxidant is bisbenzotriazole; the detergent additive is polyisobutene thiophosphate; the dispersing agent is monobutyl imide; and the extreme-pressure additive is diaryl disulfide. The composite additive for engine oil in the invention has the advantages that a preparation scheme for the composite additive is scientific; a manufacturing method for the composite additive is simple; the prepared composite additive is lower in price compared with products of a same kind and high in cost performance, obviously improves the anti-wear and anti-extreme pressure performance of mechanical equipment, decreases discharge of tail gas, reduces noise each, maximally enhances the anti-oxidation, cleaning and dispersing functions of the lubricating oil, maintains good running of mechanical equipment for a long time, prolongs an oil change period and completely enhances the comprehensive efficacy of the lubricating oil.

Problems solved by technology

[0004] With the continuous progress of human civilization, the continuous development of science and technology, all kinds of mechanical equipment are constantly updated, especially the development of the automobile industry is more prominent, so the lubricant industry in order to achieve a higher efficiency of various mechanical equipment Design requirements must also be continuously developed and innovated. At present, due to the continuous development of the automobile industry, automotive lubricants occupy half of the market for lubricants, so they are highly valued by various lubricant manufacturers and various scientific research units. In the process of lubricating oil production, additives have played a certain role, but there are a large number of various additives on the market, some of which have outstanding effects, but are expensive. Some lubricating oil manufacturers purchase low-priced additives in order to pursue profits, but production The quality and effect of the oil products produced are not ideal. Some manufacturers only use a single agent to reconcile, and the effect can be imagined

As a result, various effects are not ideal, and the oil change cycle cannot meet the ideal requirements, resulting in a great waste of energy in our country

At the same time, due to the low quality of various lubricating oils produced, the anti-oxidation and cleaning and dispersing effects are not outstanding, so that the exhaust emissions cannot meet higher requirements, and at the same time seriously affect the service life of various mechanical equipment
