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。
The two kinds of plasticizers selected, cyclohexane-1,2-dicarboxylic acid diisooctyl ester (DEHCH) and cyclohexane-1,2-dicarboxylic acid diisononyl ester (DINCH) are internationally recognized as environmentally friendly Toxic plasticizer, plasticizer 2 plasticizer mechanical properties of PVC, low temperature performance, optical performance, stability, etc. made a comprehensive comparison. The results show that the environmental plasticizer DEHCH plasticized PVC is superior to the DINCH plasticized PVC in terms of mechanical properties; the plasticizer DEHCH plasticized PVC is slightly worse in optical properties than the plasticized PVC in DINCH.
