油酸二乙醇酰胺磷酸酯对润滑油生物降解及抗磨减摩性能的影响

摘要

采用油酸、二乙醇胺和五氧化二磷为原料合成油酸二乙醇酰胺磷酸酯(简称OEAP),采用红外光谱对其主要官能团进行表征,并考察OEAP对HVI 350矿物基础油生物降解性、抗磨减摩性和抗腐蚀性的影响.结果表明,OEAP作为添加剂可有效促进HVI 350矿物润滑油生物降解,且具有良好的抗磨、减摩性能和抗腐蚀性能.%Oleic diethanolamide phosphate (OEAP) was synthesized with oleic acid,diethanolamine and phosphorus pentoxide,and its structure was characterized by means of IR spectroscopy. The impacts of OEAP as an additive on the biodegradability, corrosiveness, antiwear and friction-reducing ability of HVI 350 mineral lube base oil were investigated. Test results indicated that OEAP additive could effectively enhance the biodegradability,load carrying capacity and friction-reducing ability of HVI 350 mineral oil. Furthermore,the corrosion resistant of HVI 350 lube oil was also improved by OEAP additive.
