植物油基水性极压润滑添加剂不仅可以提高润滑剂的减摩抗磨性能，而且具有可生物降解、环境相容性好以及制备与实用工艺安全、无毒等优良特性。针对传统硼类润滑添加剂存在环境相容性和水解稳定性较差的问题，本项目以来源于林业可再生资源桐油为原料设计、合成并筛选获得新型桐油基硼-氮配位环状结构水性极压润滑添加剂 (TOWEA)。探究桐油基硼-氮配位环状结构水性极压润滑添加剂的分子理论模拟、设计和表征，探讨桐油基水性极压润滑添加剂的微观分子结构与其宏观性能构效关系的内在规律，重点研究分子结构中硼-氮配位环状结构的引入对桐油基水性极压润滑添加剂水解稳定性的影响，分析硼、氮元素的协同增效机制。本项目的实施一方面能够使绿色林业生物质资源桐油获得高附加值利用，另一方面为高水解稳定性、高极压润滑性能的硼类润滑添加剂的发展提供重要的理论指导和科技支撑。

Vegetable oil-based waterborne extreme pressure lubrication additives can not only improve the friction reduction and anti-wear properties of lubricants, and have excellent properties, such as biodegradable, good environment compatibility, the process of preparation and utilization safely and so on. Aim at the poor environment compatibility and hydrolytic stability of traditional boron-based lubricant additives, this project is plan to design, synthesis and screening new tung oil-based boron-nitrogen coordination ring structure, waterborne, extreme pressure lubrication additive by tung oil (TOWEA). This project is plan to explore the molecular theory simulation, design and characterization of the TOWEA, discuss the inherent law of the structure-function relationship between microscopic molecular structure and macroscopic properties, focus on the effect of the introduction of boron-nitrogen coordinated cyclic structure on the hydrolytic stability of TOWEA, study the synergistic mechanism of boron and nitrogen elements in detail in this work. This project will provides high value-added utilization of green forestry biomass resource tung oil, and also provides important theoretical guidance and scientific support for the development of boron-based lubricating additives with high hydrolytic stability and high extreme pressure lubrication performance.
