摘　　要：选用的2种增塑剂环己烷-1,2-二羧酸二异辛酯(DEHCH)与环己烷-1,2-二羧酸二异壬酯(DINCH)为国际公认的环保无毒增塑剂,对2种增塑剂增塑PVC的力学性能、低温性能、光学性能、稳定性能等方面做了全面的对比。结果表明:环保增塑剂DEHCH增塑PVC在力学性能方面要优于DINCH增塑的PVC;环保增塑剂DEHCH增塑PVC在光学性能方面要略差于DINCH增塑的PVC。Di （ 2-ethylhexyl ）-1, 2-cyclohexane dicarboxylate （ DEHCH ） and di （ 2-isononyl ）-1, 2-cyclohexane dicarboxylate（DINCH） were internationally accepted environmentally friendly non-toxic plastizers. The mechanical properties, cryogenic properties,optical properties and stabilities of PVC were compared by modifying effects of these two plastizers. The results showed that DEHCH modifying PVC was superior to DINCH modifying PVC in the mechanical properties; DEHCH modifying PVC was slightly worse than DINCH modifying PVC in the optical performances.
