含氮杂环硼酸酯添加剂的合成及其摩擦学性能

Preparation and Tribological Properties of N-containing Heterocyclic Borates as Lubricant Additives

摘要: 从分子设计的观点出发,合成了1种新型的含氮杂环硼酸酯添加剂.采用四球摩擦磨损试验机评价了其在液体石蜡中的摩擦学性能,并采用扫描电子显微镜观察分析钢球磨斑的表面形貌.结果表明:在液体石蜡中加入含氮杂环硼酸酯添加剂后,承载能力有较大提高,磨斑直径明显减少.

Abstract: From the point view of molecular design, a kind of nitrogen-containing heterocyclic borates as lubricant additive is synthesized. The tribological properties of nitrogen-containing heterocyclic borate as additive in liquid paraffin are investigated on a four-ball tester. The morphologies of the worn scars are observed by means of scanning electron microscopy. The results show that the load-carrying capacity and the antiwear performance of the liquid paraffin with the additive added are improved, and wear scar diameter is decreased in comparison with the base oil.
