| 中文摘要: |
| 考察了微波脱硫橡胶的再硫化历程，并分析了其硫化机理。结果表明，与普通橡胶的硫化不同，微波脱硫橡胶的再硫化历程分为脱硫橡胶中的大分子多硫自由基及大分子环状多硫化物的自交联和添加交联剂对大分子的再交联两个阶段。微波脱硫橡胶的再硫化历程显示了另一个突出的特点即焦烧时间很短，甚至没有焦烧期。 |
| 英文摘要: |
| The revulcanization Process and mechanism of microwave devulcanized rubber were investigated.The results showed that incontrast to the conventional vulcanization，the revulcanization Process of microwave devulcanized rubber were divided into twoPhases，i.e.the self-crosslinking of the macromolecularPoly sulfide radicals and the macromolecular cyclicPolysulfides in devulcanized rubber and the recrosslinking of the macromolecules with the added crosslinking agent.In addition，the revulcanization Process of microwave devulcanized rubber featured very shortor even no scorch time. |
