摘要:: 废橡胶再生技术是世界橡胶工业一直以来的研究重点和难点，有效再生废橡胶是节约资源、保护环境的必然要求。本文综述了典型的废橡胶物理、化学再生技术及原理，系统阐述并评价了双螺杆挤出机再生法、利用超临界CO2再生法、微生物再生法、力化学再生法等几种新型并具有较好应用前景的再生方法，并对废橡胶化学再生剂的最新研究进展进行了概述。废橡胶再生技术的核心是在获得较高线性化的同时，最大程度的保护橡胶主链。同时，发展一种高效、节能、环保的再生技术将是今后努力的方向。

Abstract:: Reclaiming of waste rubber has been an important and difficult point in world rubber industry, reclaiming the waste rubber effectively is essential for saving resources and protecting the environment. The typical reclaiming technologies and principles of the waste rubber are overviewed; furthermore, several novel reclaiming methods having promising applying prospect, such as method of using twinscrew extruder, method of using Supercritical Carbon Dioxide, method of microbial desulfurization and mechanochemical reclaiming method, are systematically discussed. And then, progresses in novel chemical reclaiming agent of waste rubber are also presented. The key of the reclaiming technology is to gain a high linear content while protecting the mainchain as strong as possible. As a result, to develop an effective, energy saving and environmental reclaiming method is the goal to work towards future.
