Problems solved by technology

Although traditional lubricating oil additives have good anti-wear and anti-friction properties, due to the sulfur, phosphorus, chlorine and other elements, they not only pollute the environment during use, but also easily cause corrosion and sintering of equipment, aggravate wear, and reduce The service life of the equipment; in the research of new lubricating oil additives, more and more attention is paid to the impact on the environment, and to avoid introducing elements that pollute the environment into the additives
[0004] Most of the organic lubricating oil additives have good oil solubility, and their structures are diversified. By changing the length of the carbon chain and introducing different functional groups, they can have more excellent performance in the base oil, and at the same time can avoid the introduction of sulfur, phosphorus and chlorine, etc. Elements, avoiding environmental pollution; a large number of studies have shown that organic lubricating oil additives have excellent anti-wear and anti-friction effects compared with traditional lubricating oil additives, but most organic lubricating oil additives have complex structures and tedious synthesis processes. facing enormous challenges

Abstract

The invention discloses a green efficient organic lubricating oil additive as well as a preparation method and application thereof. The green efficient organic lubricating oil additive is prepared byreacting benzotriazole with a bromination reagent. The prepared organic lubricating oil additive is simple in synthesis process, free of sulfur, phosphorus, chlorine and other elements, environmentally friendly, small in influence on the basic performance of base oil and excellent in wear resistance and friction reduction effect, corrosion to equipment can be avoided, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention belongs to the field of lubricating oil additives, in particular to a green and high-efficiency organic lubricating oil additive and its preparation method and application. Background technique [0002] Lubricating oil is widely used in various automobiles and mechanical equipment. It can not only reduce friction and reduce equipment loss, but also play a role in heat dissipation and taking away abrasive particles. Some special lubricating oils also have anti-corrosion, anti-shock, anti-rust and sealing effect. [0003] Lubricating oil is mainly composed of base oil and lubricating oil additives. Base oil mainly includes three categories: mineral base oil, synthetic base oil and biological base oil. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. Additives It can improve the deficiencies in the performance of the base oil and endow the base oil with new properties. Although tradi...
