制备了三羟甲基丙烷油酸酯（TMPTO）以及系列润滑油添加剂4-喹唑啉酮丙酸酯类化合物,分别将1wt.%添加剂溶解于TMPTO进行改性,利用UMT-3型微摩擦试验机评价改性润滑剂的抗磨损性能.根据摩擦学定量构效关系理论（QSTR）,运用比较分子相似性指数分析（CoMSIA）方法构建了添加剂抗磨损性能的摩擦学三维定量构效关系（3D-QSTR）模型.结果表明:4-喹唑啉酮丙酸戊酯、4-喹唑啉酮丙酸十四酯、4-喹唑啉酮丙酸十五酯以及4-喹唑啉酮丙酸十六酯的抗磨损性能较好;对于该类化合物,支链的存在可能对抗磨性能有不利的影响.利用立体场和疏水场构建的CoMSIA模型预测性能好,模型提示分子结构中的特定基团在特定区域内...

Trimethylolpropane trioleate (TMPTO) was prepared as base oil along with a series of 4-quinazolone propionate as lubricant additives.The additives were dissolved in TMPTO with a concentration of 1wt.％,respectively.The antiwear property of modified lubricants were evaluated by using a microtribometer (UMT-3).Based on the theory of quantitative structure tribo-ability relationship (QSTR),the three-dimensional quantitative structure tribo-ability relationship (3D-QSTR) models of antiwear property about lubricant additives were established by comp...
