Problems solved by technology

[0003] Zinc dialkyldithiophosphate (ZDDP), a commonly used lubricating additive, has good anti-wear and anti-friction properties, but poor oxidation resistance, and it contains harmful elements such as sulfur and phosphorus, which cause adverse environmental pollution. Influence, the massive use of such additives will inevitably increase the environmental pollution

Embodiment 1

[0016] Example 1: Weigh a certain amount of fatty amine octadecylamine and benzotriazole, stir and mix in a container with a molar ratio of 1:1, and heat to 90°C, react for 1 hour to obtain a heterocyclic amine salt, in The heterocyclic amine salt and the rare earth cerium naphthenic acid salt were stirred and mixed at a molar ratio of 1:3, and heated to 120°C, reacted for 2 hours, and after cooling, a brown viscous liquid was obtained, which was a dual-functional oil-soluble lubricant. additive.

Embodiment 2

[0017] Example 2: Weigh a certain amount of fatty amine octadecylamine and tolylbenzotriazole, stir and mix in a container at a molar ratio of 1:1, and heat to 100° C., react for 1 hour to obtain heterocyclic amine salt , stir and mix the heterocyclic amine salt and the rare earth lanthanum naphthenate salt at a molar ratio of 1:4, and heat to 140°C, react for 3 hours, and after cooling, a brown viscous liquid is obtained, which is a bifunctional oil Soluble lubricant additive.

Embodiment 3

[0018] Embodiment 3: Weigh a certain amount of coconut oil amine and benzotriazole, stir and mix in a container with a molar ratio of 1:1, and heat to 100° C., react for 1 hour to obtain a heterocyclic amine salt. Heterocyclic amine salt and naphthenic acid rare earth lanthanum salt were stirred and mixed at a molar ratio of 1:5, heated to 150°C, reacted for 3 hours, and after cooling, a brown viscous liquid was obtained, which was a dual-functional oil-soluble lubricant additive.

[0019] The nitrogen-containing and rare-earth metal double-functional lubricating additive prepared by the method of the present invention has good oil solubility and can be miscible with white oil or other mineral oils and synthetic oils in any proportion. When used, generally only 0.3-1.0 %, can significantly improve the anti-wear and tribological properties of lubricating oil, which is significantly better than the traditional commonly used additive zinc dialkyldithiophosphate (ZDDP). In additio...

Abstract

The invention relates to a preparation method of a bifunctional oil-soluble lubricating additive, specifically a method for preparing a bifunctional lubricating additive containing nitrogen and rare earth metal, and belongs to the technical field of chemical and chemical lubricating additive manufacturing technology. The method of the present invention is as follows: take a certain amount of fatty amine, add nitrogen heterocyclic compound, heat and stir to mix, then add naphthenic acid rare earth metal salt, stir and mix, heat and react, and then cool to obtain brown viscous liquid, which is double-functional Oil-soluble lubricant additives. The nitrogen-containing and rare-earth metal bifunctional lubricating additive prepared by the method of the invention has good oil solubility, can be miscible with white oil or other mineral oils, and synthetic oils in any proportion, and has excellent anti-wear and anti-friction properties , Excellent extreme pressure and other advantages, especially suitable for phosphorus-free high-efficiency anti-wear additives for anti-wear hydraulic oil, gear oil or engine oil, especially suitable for anti-wear additives used under high-load conditions.

Description

technical field [0001] The invention relates to a preparation method of a bifunctional oil-soluble lubricating additive, specifically a method for preparing a bifunctional lubricating additive containing nitrogen and rare earth metal, and belongs to the technical field of chemical and chemical lubricating additive manufacturing technology. Background technique [0002] In order to improve the tribological properties of existing lubricants and reduce their pollution to the environment, in order to meet the development of machinery to heavy load and high speed and the increasingly stringent requirements of environmental protection, extreme pressure and anti-wear and other lubricating additives are becoming diversified, efficient, and Development in the direction of multi-functional and green. [0003] Zinc dialkyldithiophosphate (ZDDP), a commonly used lubricating additive, has good anti-wear and anti-friction properties, but poor oxidation resistance, and it contains harmful ...
