摘要

开发高效、低能耗、环境友好的橡胶再生方法对橡胶工业的绿色可持续发展具有重要意义。其中，废旧橡胶再生用解交联化学助剂的选择尤为关键。本文介绍了橡胶的再生机理，并根据作用机理分类，将解交联助剂归纳为自由基类、亲核类、相转移催化类、烯烃复分解类、催化类与氧化类等6类，总结了各类助剂的作用机理及研究进展，并讨论了其应用技术瓶颈。最后，展望了废旧橡胶再生利用面临的挑战和未来发展方向。

Abstract

Efficient

energy-saving and environment-friendly rubber reclaiming method is of significance to realize the green and sustainable development of rubber industry. The selection of de-crosslinking chemical agents is the key for waste rubber reclamation. The reclamation mechanism of rubber was introduced. And six types of de-crosslinking agents were categorized according to the mechanism: free radical

nucleophile

phase transfer catalysis

olefin metathesis

catalysis and oxidation. The mechanism and research progress of various agents were reviewed. Subsequently

the shortcomings of their application technology were also discussed. Finally

the challenges and future development of waste rubber recycling were recommended.
