本文介绍了国内外无灰抗磨液压油使用含磷抗磨剂的研究进展。结果表明,二烷基硫代磷酸丙烯酸酯衍生物具有优良的极压抗磨和热氧化安定性,适用于高档无灰液压油的开发。 This paper introduces the research progress of using phosphorus-containing antiwear agent in ashless antiwear hydraulic oil at home and abroad. The results show that dialkyl thiophosphate acrylate derivatives with excellent extreme pressure anti-wear and thermal oxidation stability, suitable for high-grade ash-free hydraulic oil development.
