摘　　要：以邻苯二甲酸酐、新戊二醇和油酸为原料合成了复合酯,测定了复合酯的流变学性能、生物降解性能和摩擦学性能。结果表明,复合酯的粘度范围宽,40℃的粘度在135~331mm2/s之间,粘度指数约为130,凝点低于-38℃,其中聚合度为1.42的复合酯的最大无卡咬负荷为784N,磨斑直径为0.40mm,优于矿物油。生物降解率大于75%,热分解温度大于300℃,因此复合酯是一类性能优良的合成酯类油。The complex esters were synthesized from phthalic anhydride,neopentyl glycol and oleic acid.The rheological property, biodegradability and tribological property were investigated.The results show that the complex esters have wide viscosity,in the range of 135～331 mm2/s at 40 ℃ and viscosity indices are about 130,solidifying points are lower than -38 ℃.The maximum non seizure load of complex ester of degree of polymerization 1.42 is as high as 784 N,and wear scar diameter is 0.40 mm,and superior to mineral o...
