摘　　要：合成了一种水溶性改性抗磨剂壬基酚聚氧乙烯醚磷酸锌配合物（ZnDDP—EO），并对其中间体壬基酚聚氧乙烯醚磷酸酯的合成条件进行了探讨，得出了较佳的合成工艺条件，即：原料摩尔比（OP-10：P2O5）为（2．0—2．5）：1．0，反应温度为100℃，反应时间为4—5h。利用四球试验机考察了水溶性抗磨剂在水中的润滑性能。结果表明，该剂在水中具有优良的承载能力和抗磨减摩性能。Auger电子能谱（AES）的分析显示出该剂的抗磨性能与摩擦表面中存在锌、磷等活性元素有关。An aqueous modified anti-wear additive, complex of zinc with oxyethylenated-nonylphenol phosphate （ZnD- DP-EO） was synthesized. An optimum process condition was determined by studying the preparation of its mid-product, oxyethylenated nonylphenol phosphate ester,the optimism conditions： the molar ratio of oxyethylenated nonylphenol （OP- 10） and P2O5 is （2. 0 -2.5 ）：1.0, reaction temperature is about 100 ℃, refluxing time is 4 - 5 hours. Its lubrication properties in water were evaluated using a four-ball machine. Test results show that the agent possesses good load-carrying capacity and anti-wear properties. Furthermore, the elemental compositions of the rubbing surface were investigated through Auger Electron Spectroscopy （AES）, which shows that anti-wear properties of these complexes are related to Zn, P and other active elements existed on rubbing surface.
