含氮硼酸酯对蓖麻油润滑性能的影响

为改善植物油的润滑性能，探索含氮硼酸酯作为添加剂应用于植物油的可行性，以蓖麻油为基础油，某含氮硼酸酯为添加剂，配制4种不同质量分数的混合蓖麻油，分别在红外光谱仪、热重分析仪、四球摩擦磨损试验机、扫描电子显微镜( SEM)上考察其理化性能和润滑性能，探讨含氮硼酸酯对蓖麻油的作用机理。结果表明：该含氮硼酸酯与蓖麻油具有良好的相溶性和水解稳定性的油基润滑添加剂，并且可以明显改善蓖麻油的抗磨减摩性能。

Lubrication Properties of Nitrogen-Containing Borate as Castor Oil Lubricant Additives

ln order to improve the lubricating properties of vegetable oil, the probability that nitrogen-containing boratewas used as additives in vegetable oil was discussed. Castor oil as the base oil, nitrogen-containing borate as additive.four kinds of different mass fractions of castor oils were prepared respectively. The physical and chemical performancesand lubrication properties of mixed castor oils were investigated by the infrared spectrometer. thermo gravimetricanalyzer, four-ball friction testing fig, and SEM. The mechanism of nitrogen-containing borate on castor oil wasexplored. The results show that: nitrogen-containing borate is a kind of oil-based lubricant additive that has goodcompatibility and hydrolytic stability with castor oil. and can significantly improve the antiwear properties of castor oil.
