中文摘要：

通过在油酸甲酯分子双键位置进行化学改性,合成制备了一种油酸甲酯型含氮硼酸酯类润滑添加剂.使用傅里叶红外光谱仪对合成产物化学结构进行了表征确认,采用四球摩擦实验机对其在液体石蜡和菜籽油两种不同基础油中的抗磨减摩特性进行了考察.研究结果表明,硼化改性后,油酸甲酯极压性能和抗磨减摩性能明显提高;在不同基础油中添加量为1.5%时,PD 值可分别达2452,1569N,较油酸甲酯分别提高98.38%,26.94%,并可使磨斑直径最大减小8.93%,使摩擦系数最大减小12.48%;就综合性能而言,硼氮化改性油酸甲酯对菜籽油的感受性要好于液体石蜡.

英文摘要：

In this paper,the boric acid ester containing nitrogen was synthesized by chemical modification in double bond of methyl oleate molecule.The synthetic product’s chemical structure was characterized by infrared spectroscopy.Four ball friction test machine was adopted to investigate into it’s tribology performance in differ-ent base oils,namely the liquid paraffin and rapeseed oil respectively.The results show that,after modification, the anti-wear ability,extreme-pressure performance and anti-friction performance of methyl oleate were im-proved significantly.With 1.5% additive amount of synthetic product in different base oils,PD reached to 2 452 and 1 592 N,increased 98.38% and 26.94% comparing with methyl oleate,WSD reduced 8.93% and friction co-efficient reduced 12.48%.For tribology performance,the perceptibility property of the chemical modification methyl oleate is much better to the rapeseed oil than to the liquid paraffin.
