新型生物基热塑性弹性体及其制备分析

Analysis of Novel Biobased Thermoplastic Elastomers and Their Preparation

以生物基材料氢化苯乙烯-β-法尼烯嵌段共聚物为基材,添加一定量聚己二酸/对苯二甲酸丁二醇酯或聚乳酸、无机填料以及抗氧剂,制备得到新型生物基热塑性弹性体。测试结果表明,弹性体的剥离强度主要与熔融指数有关,熔融指数越高剥离强度越大,循环10次的循环拉伸其弹性回复率大于90%,所制备得到的塑性弹性体具有良好的降解性能、分子量较高,弹性良好等优异性能。

This article uses hydrogenation of styrene using bio based materials-β-Farnesene block copolymer as the substrate,adds a certain amount of polyadipic acid/butylene terephthalate or polylactic acid,inorganic fillers,and antioxidants,to prepare novel bio-based thermoplastic elastomers.The test results show that the peel strength of the elastomer is mainly related to the melt index.The higher the melt index,the greater the peel strength.The elastic recovery rate of the elastomer is more than 90%after 10 cycles of stretching.The prepared plastic elastomer has good degradation performance,high molecular weight,good elasticity and other excellent properties.
