摘　　要：利用铁氧体的吸波特性,采用微波技术对废胶粉进行脱硫再生,优化再生工艺条件,研究磁性再生橡胶的性能。结果表明:在微烟条件下微波脱硫3次可以得到物理性能较好的磁性再生橡胶;在微波脱硫过程中加入一定量的松香有助于促进废胶粉脱硫,并明显改善磁性再生橡胶的加工性能;在混炼过程中加入少量古马隆树脂和环烷油能够明显改善磁性再生橡胶的加工性能。Utilizing the microwave absorbing property of ferrite,the waste rubber powder was devulcanized and regenerated by using microwave technology,the regeneration processing condition were optimized,and the properties of the magnetic reclaimed rubber compound were investigated.The results showed that magnetic reclaimed rubber with good properties could be obtained on the condition of microwave radiation for three times under mild smoke.The desulfurization and the processing performance of magnetic reclaimed rubber could be obviously improved by addition of rosin in the microwave devulcanizing process. The processing performance of magnetic reclaimed rubber could be obviously improved by addition of coumatone resin and naphthenic oil in the mixing process.
