Abstract

The invention discloses a multifunctional lubricant additive for a dithioamino acid triazine derivative and a preparation method and application of the multifunctional lubricant additive. The dithioamino acid triazine derivative is of a structure shown as a general formula I. The preparation method comprises the following steps: firstly introducing dialkyl amine onto a tri-polychlorostyrene piperazine structure, then introducing 2-mercaptobenzothiazole, and finally carrying out a nucleophilic substitution reaction with carbon disulfide and dialkyl amine or piperidine to obtain the multifunctional lubricant additive for the dithioamino acid triazine derivative shown as the general formula I. The dithioamino acid triazine derivative has the characteristics of simple preparation method, mildtechnological conditions, easily obtained raw materials, low synthesis cost, high synthesis yield and the like; the derivative can be used for extreme pressure, abrasion resistance, antifriction of alubricant and application of an anti-corrosion additive, the bearing capacity of base oil can be obviously improved, the abrasion resistance and antifriction performance are improved, and the additiveis an environmentally-friendly multifunctional lubricant additive.

Description

Technical field: [0001] The invention relates to the field of lubricating oil additives, in particular to a multifunctional lubricating oil additive based on arsenic-s-triazine derivatives. Background technique: [0002] Lubricating oil plays an important role in the national economy due to its characteristics of energy saving, consumption reduction and friction and wear reduction. The addition of various lubricating oil additives can make the lubricating oil exhibit different characteristics, so as to meet different operating conditions. Anti-wear and extreme pressure additives are the focus of research. With the strengthening of people's awareness of environmental protection, the use of zinc dialkyl dithiophosphate (ZDDP), which is widely used in extreme pressure and anti-wear additives, has been restricted. [0003] Nitrogen-containing heterocyclic compounds not only have compact structures, good tribological properties, but also have little harm to the environment. In ...
