【摘要】设计合成了4种含氮杂环的酯或酰胺类衍生物润滑油添加剂 (Ⅰ~Ⅳ) 。采用核磁共振氢谱 (1H NMR) 和飞行时间质谱 (MALDI-TOF-MS) 对所得产物的结构进行了表征;研究了4种添加剂的油溶性、热稳定性和抗腐蚀性;在四球摩擦磨损试验机上系统考察了添加剂在液体石蜡中的摩擦学性能;利用扫描电子显微镜 (SEM) 和能谱分析仪 (EDS) 观察和分析了钢球磨斑的表面形貌和元素组成。结果表明, 4种添加剂均具有良好的油溶性、热稳定性和抗腐蚀性, 当添加剂Ⅰ的质量分数达到1.0%时, 钢球的磨斑直径 (WSD) 和摩擦系数分别比在液体石蜡中降低了33%和26%。SEM结果显示4种添加剂的加入能明显减小WSD, 减少表面磨损, EDS结果表明添加剂在摩擦过程中形成了复杂的反应膜。
