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 twinscrew 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 mainchain as strong as possible. As a result, to develop an effective, energy saving and environmental reclaiming method is the goal to work towards future.
