Two kinds of phenol- and N- containing borate ester, BTEB and BMEB have good hydrolysis stability due to the B-N coordination bond. The PB value improved by 60.7% and 67.6% respectively at 0.5wt% BTEB, BMEB in rapeseed oil. Their antiwear effect increases with the increase of adding content, and BMEB is better than BTEB. The friction-reducing effect of BTEB is better than BMEB. All additives formed a protective film which containing BOx, FeOx and other organic nitrogen compounds. The better capacities of BMEB may due to the complex boundary lubricating film which contain ferrous sulfate, ferrous sulfide. All additives possessed good antioxidation effect, and it increased the oxidation activation energy than rapeseed oil by 51.15% and 78.82% respectively at 0.25wt%.
两种含酚和氮的硼酸酯，BTEB 和 BMEB 由于 B-N 配位键而具有良好的水解稳定性。在油菜籽油中，0.5wt%BTEB 和 BMEB 分别使 PB 值提高了 60.7%和 67.6%。它们的抗磨效果随添加量的增加而增加，且 BMEB 优于 BTEB。BTEB 的减摩效果优于 BMEB。所有添加剂均形成了含有 BOx、FeOx 和其他有机氮化合物的保护膜。BMEB 可能具有更好的性能，因为它形成了含有硫酸亚铁、硫化亚铁的复杂边界润滑膜。所有添加剂均具有良好的抗氧化作用，在 0.25wt%时，分别比油菜籽油的氧化活化能提高了 51.15%和 78.82%。
