摘要/Abstract

摘要： 以2,5呋喃二甲酸为基体分别与反式2己烯醇、正己醇反应，制备出不同分子结构的生物基增塑剂。通过冲击、拉伸测试并结合动态力学分析考察增塑剂分子结构及添加量对聚氯乙烯(PVC)力学性能的影响；采用毛细管流变仪考察增塑剂分子结构及添加量对PVC熔体流动性的影响。结果表明,2种新型生物基增塑剂均能提高PVC材料的冲击强度，且2,5呋喃二甲酸二正己酯（DNHFDC）增塑效果优于2,5呋喃二甲酸二（反式2己烯）酯（DT2HFDC）;当添加量为10份（质量份，下同）时，以DNHFDC为增塑剂的PVC材料比添加等量DOP时的冲击强度提高了0.28 kJ/m2，拉伸强度降低了4.2 MPa。

Abstract: A series of bio-base plasticizers with different molecular structures were prepared by the reaction of 2,5-furan-dicarboxylic acid with trans-2-hexenol and n-hexanol. The effects of the molecular structure and amount of plasticizers on the mechanical and rheological properties of PVC compounds were investigated by means of impact test, tensile test, dynamic mechanical analysis and capillary rheometer. The results indicated that the impact strength of PVC compounds were improved with the addition of two new bio-base plasticizers, and 2,5-dihexyl furan-dicarboxylate exhibited a better plasticizing effect on PVC than 2,5-di-(trans-2-hexene furan-dicarboxylate)ester. When 10 phr of 2,5-dihexyl furan-dicarboxylate was added, the PVC compound obtained an increase in impact strength by 0.28 kJ/m2 but a decrease in tensile strength by 4.2 MPa compared to the compound containing the same content of dioctyl phthalate.
