合成了一种新型水溶性三嗪衍生物2,4-二-(二乙醇胺)-6-(二乙醇胺二硫代氨基甲酸酯)-1,3,5-三嗪。作为纯水和水-乙二醇的添加剂，通过四球试验机对其摩擦学性能进行了评价。结果表明，这种新型三嗪衍生物表现出优异的极压、抗磨和减摩性能。该化合物可作为新型多功能润滑油添加剂在纯水和水-乙二醇中使用。在使用水-乙二醇作为基液的条件下，磨痕直径和摩擦系数随着转速的增加而增大。采用扫描电镜、X射线能谱仪、X射线光电子能谱仪对磨损表面形貌及表面元素成分进行了分析。分析结果表明，添加剂生成了边界润滑和保护膜，膜中含有FeOx、FeSO4、FeS2和有机含氮化合物。这一结果可能有助于改善水基润滑剂的摩擦学性能。
2,4-Di-(diethanolamine)-6-(diethanolaminedithiocarbamate)-1,3,5-triazine, a novel water-soluble triazine derivative, was synthesized. As additive in pure water and water-glycol, its tribological behaviors were evaluated by a four-ball tester. The results showed that this new triazine derivative exhibited excellent extreme pressure, antiwear, and friction-reducing properties. The compound can be used as a new multifunctional lubricant additive in pure water and water-glycol. The wear scar diameter and friction coefficient increased along with the rotation speed under the condition of using water-glycol as base liquid. The morphology of worn surface and the element composition of the surface were analyzed by scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy. The analysis results showed that the additive generated a boundary lubricating and a protecting film, which contained FeOx, FeSO4, FeS2, and organic N-containing compounds. This consequence may contribute to the improvement of tribological properties of water-base lubricant.
