| 摘 要： | 采用润滑剂生物降解快速测定仪和四球试验机研究了制备的油酸三（2-羟乙基）异氰尿酸磷酸酯（简称OHTP）对400 SN矿物基础油生物降性和摩擦学性能的影响，考察了其油溶性，并利用扫描电子显微镜（SEM）和X射线光电子能谱（XPS）分别分析了磨斑的表面形貌及元素的化学状态。试验结果表明：OHTP具有良好的油溶性，明显提高了基础油的生物降解性、极压性能和抗磨减摩性能；XPS的分析表明OHTP在摩擦表面形成了由吸附膜和摩擦化学反应产生的FePO4, Fe3(PO4)2, Fe2O3 及 Fe3O4的化学反应膜组成的复杂的边界润滑膜，从而提高了基础油的极压、抗磨和减摩等摩擦学性能。

| Abstract: | The oil solubility of synthetic oleic acid tris (2-hydroxyethyl) isocyanurate phosphate ester (denoted as OHTP) and its influence on the biodegradability and tribological performances of 400 SN mineral oil were investigated on a tester for fast evaluating biodegradability of lubricants and a four-ball tribotester, respectively. Furthermore, the morphologies and tribochemical species of the worn surfaces lubricated by OHTP-doped oil were studied by scanning electron microscope (SEM) and X-ray photoelectron spectroscope (XPS). The results indicated that OHTP possessed excellent oil solubility and improved obviously the biodegradability, the extreme pressure properties, the anti-wear properties and friction-reducing properties of neat mineral oil. The analytical results of XPS spectra showed that the composite boundary lubrication films were mainly composed of absorbed films and tribochemical species such as FePO4, Fe3(PO4)2, Fe2O3 and Fe3O4, which contributed to improving the tribological performances. |
