摘要:本文合成了含氮杂环硼酸酯润滑油添加剂，考察了反应时间、温度、摩尔比对产率的影响。实验证明以菜籽油为原料与甲醇酯化，中间体菜籽油二乙醇酰胺：硼酸：正己醇的摩尔比为1:1:1，温度控制在120℃，时间为6h是最适宜的反应条件，产率为81.6%。利用四球摩擦试验机考查了含氮杂环硼酸酯在基础油中的摩擦学性能，实验证明含1.5%含氮杂环硼酸酯时抗磨性能较好；测定基础油、添加1.5%含氮杂环硼酸酯的基础油及添加T202的基础油三者的最大无卡咬负荷PB，结果表明添加含氮杂环硼酸酯的基础油PB值最大。最后测定含氮杂环硼酸酯与T202复配后的摩擦性能以及两者的添加量对基础油的摩擦磨损性能的影响，结果表明当添加1.5%含氮杂环硼酸酯和添加1%T202复配时，润滑油的抗磨效果最佳。6759

Study On Tribological Characteristic And Synthesis Of Nitrogen Containing Heterocyclic Borate Ester
Abstract： This article synthesized Nitrogen containing heterocyclic borate ester studying the effects of reaction time, temperature, molar ratio to the production rate.It’s proved that rapeseed oil as a raw material esterified with methanol。Rapeseed oil diethanolamide: Boric acid: n-hexyl alcohol molar ratio of 1:1:1. The temperature is controlled at 120 ℃.The time is controlled at 6 hours.These are the most suitable reaction conditions which yield was 81.6%. We use four-ball friction tester to examine the tribological properties of the nitrogen containing heterocyclic borate ester in the base oil . Experiments show that the base oil containing 1.5% the nitrogen-containing heterocyclic borate ester is better in anti-wear performance. We made a determination of base oil, base oil adding 1.5% nitrogen containing heterocyclic borate ester and base oil adding the T202 to find the largest PB. The results show that base oil adding a nitrogen-containing heterocyclic has the maximum PB. Finally we made a determination of nitrogen containing heterocyclic borate ester compounding with T202. The results show when base oil adding 1.5% nitrogen containing heterocyclic borate ester complexing the base oil adding 1% T202, the anti-wear lubricants is best.
