| 摘 要： | 合成两种含氮硼酸衍生物抗磨添加剂:长链烷基醇胺硼酸钙ODOB-Ca、长链烷基醇胺和长链烷基苯酚的硼酸酯DPOB,分别用元素分析和红外光谱对分子结构进行表征.用热重分析仪考察两种化合物的热稳定性,用饱和蒸汽法考察其水解稳定性,发现这两种化合物均具有良好的热稳定性和较好的水解稳定性,其水解稳定性分别为硼化聚异丁烯基丁二酰亚胺(T154B)的3倍和10倍；用立式万能摩擦磨损试验机考察了ODOB-Ca和DPOB的摩擦学性能以及与ZDDP的配伍性能,结果表明两种化合物作为矿物基础油均具有较好的抗磨性能,且均与ZDDP在一定比例配伍,有很好的协同作用.采用XPS考察了钢球磨斑表面成份,结果显示钢球磨斑表面形成了B2O3、铁的氧化物以及硫酸化合物等多组分混合边界润滑膜,从而使配伍体系摩擦学性能得以改善.

| Abstract: | Two kinds of N-containing boric acid derivatives, referred to as ODOB-Ca and DPOB, as lubricating oil additives were synthesized to replace or partially replace ZDDP and characterized using infrared spectroscopy and element analysis. The two additives showed good thermal stabilities in air. The hydrolytic stabilities of ODOB-Ca (37 h) and DPOB (92 h) determined by saturation vapor pressure were better than that of T154B (9 h). Their tribological behaviors as additives in mineral oil and synergetic effects with ZDDP were evaluated on a four-ball friction and wear tester. The results show that two synthesized compounds as additives in mineral oil exhibited good anti-wear property. Synergic effect of compound ODOB-Ca/DPOB and ZDDP in terms of the anti-wear property was observed. The tribofilm which is composed of B2O3, iron oxide and sulphates was revealed by X-ray photoelectron spectroscopy surface analysis. |
