摘　　要：考察了乙酰基柠檬酸三正丁酯(ATBC)、偏苯三酸三辛酯(TOTM)和环己烷-1,2-二羧酸二异壬酯(DINCH)三种环保增塑剂对聚硫密封剂性能的影响,并与传统增塑剂邻苯二甲酸二丁酯(DBP)进行了对比分析。研究结果表明:ATBC样品的工艺性能、粘接性能与DBP样品基本相当,但拉伸强度和硬度低于DBP,而断裂伸长率、耐介质性能和耐热性能优于DBP。因此,ATBC可替代DBP作为聚硫密封剂的绿色增塑剂。The effects of three environmental friendly plasticizers,i.e.acetyl tri-n-butyl citrate(ATBC),trioctyl trimellitate(TOTM)and di-isononyl-cyclohexane-1,2-dicarboxylate(DINCH)on the properties of polysulfide sealant were investigated and compared with the traditional plasticizer dibutyl phthalate(DBP).The research results showed that the processing properties and bonding properties of ATBC samples were basically equivalent to those of DBP samples,but the tensile strength and hardness were lower than those of DBP,while the elongation at break,medium resistance and heat resistance were better than that of DBP.Therefore,ATBC could replace DBP as green plasticizer for polysulfide sealant.
