【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 nitrogen-containing triazine heterocyclic derivative 2o 4- dioxane was synthesized from cyanuric chloride and diethanolamine. N-dihydroxyethylamino-6-hydroxy-3-triazine (CDDAA) water-based lubricating additive was prepared by using CDDA as raw material to prepare a new additive, 2-dimorpholinyl-6-hydroxy-3-triazine (CMDAA). The structure was characterized by FTIR, elemental analysis and ESI-MS. The thermal stability and solubility of CDDA and CMDA were investigated. The friction-reducing, antiwear and extreme pressure properties of CDDA and CMDA as water-based lubricating additives were studied by four-ball friction and wear test. The morphologies and elements of friction surfaces were observed and analyzed by SEM and EDS. The results showed that the synthesized products were the target products CDDA and CMDA. under the same experimental conditions. The decomposition temperature range of CMDA is 278.26 鈩，
