演讲题目：
可熔融回收双交联网络EVA超临界流体微发泡材料研究
Fabrication of recyclable EVA foam with dual crosslinking networks blown with supercritical fluid
演讲提纲：
EVA具有优异的发泡行为、配方可设计性、可加工可染色性，是最重要的鞋用发泡材料。不过，化学交联结构让EVA发泡材料难以熔融回收。本研究通过同时引入化学交联剂和动态交联剂，在EVA中形成可熔融回收的双交联网络。所制备的EVA可以超临界流体发泡，交联EVA泡沫可以熔融回收并进行二次发泡;同时，双交联EVA泡沫具有优异的能量吸收性能。
EVA is an important shoe foam material, which present excellent foaming behavior, good formulation designability, easy to process, and excellent dyeability. However, the chemical cross-linked structure makes it difficult to melt and recycle. The main target of this study is to fabricate a recyclable EVA formation with the dual crosslinked network by simultaneously introducing chemical crosslinking agent and dynamic crosslinking agent. The as-prepared crosslinking EVA presents good foaming behavior blown in supercritical N2, and the crosslinked EVA foam can be melted and recycled, and the recycled EVA raw resin can be secondary foamed. Meanwhile, the dual crosslinked EVA foam has a superior energy absorption efficiency of 84.1%.
