Problems solved by technology

Although fatty acid anti-wear agents can significantly improve the anti-wear performance, it is easy to cause metal corrosion
Fatty acid esters are mainly prepared from long-chain unsaturated fatty acids and polyols. The cost of raw materials for polyols is high, and the product may contain unreacted fatty acids
The problem with the derivatives of fatty acid amides or fatty acid salts is the selectivity of oil products. In some experiments, the anti-wear properties of diesel oil can be improved, but in some experiments, the anti-wear properties of diesel oil can be reduced.

Abstract

The invention relates to a low-sulfur diesel lubricating anti-wear agent, which is prepared by uniformly mixing at least one ester oily component, at least one amide oily component and at least one low-sulfur solvent component in a mechanical blending manner to make. The present invention starts from the reality of improving the wear resistance of low-sulfur diesel oil, and has the functions of increasing lubrication, improving oxidation stability, and high-efficiency cleaning. The quality of diesel products produced by the factory is high, and the addition process is simple, which can reduce production costs while improving product quality. The lubricating antiwear agent prepared by the invention can be applied to low-sulfur diesel oil, and can obviously improve the lubricating performance of the diesel oil.

Description

technical field [0001] The invention belongs to the technical field of preparation of chemical products, and relates to a diesel additive, in particular to a low-sulfur diesel lubricating antiwear agent which can be used to produce high-power clean diesel. Background technique [0002] As the country and all walks of life pay more and more attention to environmental protection issues, the production of high-quality oil products has become the development direction of the modern oil refining industry. In terms of vehicle diesel production, the improvement of oil standards is mainly reflected in the reduction of sulfur content, and the level of sulfur content is an important indicator that determines the cleanliness of vehicle exhaust. Sulfur is the most harmful element that increases CH and CO in diesel engine emissions, especially inhalable particulate matter, so reducing the sulfur content in diesel is particularly important to improve air pollution. In view of the fact th...
