可生物降解汽油机油基础油抗氧化性能试验

Anti-oxidation behavior of biodegradable lube base oil

针对菜籽油应用于润滑油基础油抗氧化性能比较差的缺点 ,合理地选用在矿物基润滑油中作用性能良好的抗氧剂 ,考察其对菜籽油抗氧性能的影响。试验表明 ,DNA和 Tp 两种添加剂能显著提高菜籽油的抗氧化性能 ;T2 0 2、Cu DTP等在矿物基润滑油中起着优良抗氧化性能的添加剂在菜籽油中作用效果不显著 ;在矿物油中兼起抗氧作用的 T70 6在以菜籽油为主的基础油中抗氧抗腐效果不显著。

With the shortage of rape oil on the oxidation resistance,several antioxidants which have excellent performance in mineral lube are chosen reasonably, and the anti-oxidation performance is investigated. The results indicate that DNA and T p can improve anti-oxidation performance of rape oil remarkably, and T202, CuDTP and T706 don't possess the performance.
