无硫磷三嗪杂环衍生物水基润滑添加剂的制备及其摩擦性能
Synthesis and tribological properties of non-phosphorus and sulfur-free heterocyclic derivatives of triazine as lubricant additives in water
摘要
Abstract
A non-phosphorus and sulfur-free triazine derivative lubricant additive 2,4-bi(N,N- bihydroxyethylamino)-6-hydroxyl-sym-triazine(named as CDDA)was synthesized using cyanuric chloride and diethanol amine as raw materials. Another non-phosphorus and sulfur-free triazine derivative lubricant additive 2,4-bimorpholinyl-6-hydroxyl-sym-triazine(named as CMDA)was synthesized using CDDA as raw material. The structure of CDDA and CMDA were characterized by FTIR,elemental analysis and ESI-MS. The solubilities of CDDA and CMDA in water were tested and their thermal stabilities were studied by thermal analysis. The friction reducing,anti-wear and load-carrying capacities of CDDA and CMDA in water were investigated by four-ball testing. The surface morphology and the elemental composition of the tribofilms were investigated using scanning electron microscopy(SEM)and energy dispersive X-ray spectroscopy (EDS),respectively. The results revealed that the synthetic products were the target compounds CDDA and CMDA. They were completely dissolved and had good soluble properties in water. The decomposition temperature of CMDA and CDDA ranged from 278.26℃ to 460.15℃,and from 110.46℃ to 457.58℃,respectively,the thermal stability of CMDA was better than that of CDDA. CDMA exhibited better tribological performances than CDDA under different experimental conditions of test loads and additive concentrations. The excellent tribological property of CMDA may be due to the nitrogen heterocyclic structure and more heterocyclic structure in its molecule, which plays an important role in extreme pressure and anti-wear of boundary lubrication.关键词
