摘　　要：文章介绍了磷酸酯胺盐极压添加剂的合成,并采用四球实验对其在不同基础油中极压、抗磨和减摩性能进行了评价。研究表明,磷酸酯胺盐类化合物基本不具备抗磨性,但表现出优秀的抗极压性能,可大幅度提高不同润滑油的PB和PD值,并有效降低酯类油和含有酯类油的聚α-烯烃(PAO)油品的摩擦系数。磷酸酯胺盐类添加剂还具有高梯姆肯OK值和不腐蚀有色金属的特点。磷酸酯胺盐添加剂可以应用于工业油、齿轮油、金属加工液、润滑脂和航空润滑油等领域。The amine phosphate compounds＂ syntheses were introduced and their friction - reducing, antiwear and EP per- formances in different base oils were evaluated with four - ball test machine. The research indicated, although the additives exhibit almost no antiwear property, but possess excellent EP performances, by which PB and PD can increase greatly in different base oils; the additives can also reduce obviously the friction coefficient of ester and ester - containing poly α - ole- fin （PAO） base oils. The additives can also improve lubricant＇s Timken EP performance, and does not corrode non -ferrous metals due to no content of sulfur. The additives can be used in industrial oil, gear oil, metalworking fluid, grease and avia- tion oil.
