摘要: 以三聚氯氰和二乙醇胺为原料合成出一种含氮、但不含硫磷的三嗪杂环衍生物2,4-二(N,N-二羟乙氨基)-6-羟基-均三嗪(CDDA)水基润滑添加剂,以CDDA为原料制得一种添加剂2,4-二吗啉基-6-羟基-均三嗪(CMDA),并采用FTIR、元素分析以及电喷雾电离质谱(ESI-MS)对其结构进行了表征。考察了CDDA和CMDA的热稳定性及溶解性;采用四球摩擦磨损试验研究了CDDA和CMDA用作水基润滑添加剂的减摩、抗磨以及极压性能;并采用SEM和EDS观察和分析了摩擦表面的形貌特征及元素。研究结果表明,合成的产物为目标产物CDDA和CMDA。在相同的实验条件下,CMDA的分解温度范围是278.26~460.15℃,CDDA的分解温度范围是110.46~457.58℃,CMDA的热稳定性优于CDDA;在不同载荷、添加比例等条件下CMDA的摩擦学性能优于CDDA。CMDA优异的摩擦学性能得益于含有更多的杂环结构,在摩擦过程中,添加剂与摩擦副表面发生化学反应,生成了含氮杂环的复合边界润滑膜,起到极压、抗磨的作用。

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 wereinvestigated 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.

Key words: non-phosphorus and sulfur-free, triazine derivatives, water lubricant additive, synthesistribological properties
