有机硼酸酯作为一种新型多功能润滑油添加剂，具有优良的减摩抗磨性能，但和所有的酯类一样，普通硼酸酯非常容易水解，从而使润滑油的减摩、抗磨性能下降。笔者以在硼酸酯分子中引入配位键从而降低硼的缺电子性为出发点，合成出一种水解稳定性高、抗磨减摩性好的六元环亚胺型含氮硼酸酯，经测试水解时间为17d。并用四球试验机考察了它的润滑性能，在液体石蜡基础油中，质量分数为3％时极压抗磨效果最好，磨斑直径减小16．67％，同时PB值提高22．86％，PD值提高26，94％。

유궤붕산지작위일충신형다공능윤활유첨가제，구유우량적감마항마성능，단화소유적지류일양，보통붕산지비상용역수해，종이사윤활유적감마、항마성능하강。필자이재붕산지분자중인입배위건종이강저붕적결전자성위출발점，합성출일충수해은정성고、항마감마성호적륙원배아알형함담붕산지，경측시수해시간위17d。병용사구시험궤고찰료타적윤활성능，재액체석사기출유중，질량분수위3％시겁압항마효과최호，마반직경감소16．67％，동시PB치제고22．86％，PD치제고26，94％。
Organic boric acid ester as a new multi-functional lubricating oil additives, with excellent tribological performance, However, all of the esters, Ordinary boric acid ester is very easy hydrolysis, so that the friction-reducing lubricants, anti-wear performance. Author to the introduction of the coordination bond in the boric acid ester molecules in order to reduce the boron electron-deficient as a starting point, Synthetic a high hydrolytic stability, abrasion antifriction good six-membered ring imine nitrogen-containing boric acid ester, hydrolysis time has been tested for 17 days. Examine the performance of the lubrication and four-ball test machine, liquid paraffin base oil, the mass fraction of the pressure and antiwear effect of 3 %, the best wear scar diameter is reduced by 16.67 %, while the PB value increased by 22.86 %, the PD value increased by 26.94 %.
