Method for desulfurizing rubber

The invention relates to the technical field of production of reclaimed rubber, in particular to a method for desulfurizing rubber. In a process of feeding, heating and stirring waste rubber powder ina stirring type desulfurizing tank, clear water is added into the desulfurizing tank every 1-3 min when the waste rubber is desulfurized, so that the waste rubber powder is continuously wetted, the circumstance that the waste rubber is locally agglomerated and burnt in the stirring and heating desulfurizing process can be effectively avoided, the circumstance that toxic smoke is generated due toscorching of the waste rubber is avoided, and on the premise of not influencing the performance of the desulfurized rubber, the rubber desulfurizing process is environmentally friendly. 本发明涉及再生橡胶生产技术领域，特别涉及一种橡胶脱硫方法；通过在废橡胶粉投入搅拌式脱硫罐内加热并搅拌的过程中，通过在废橡胶脱硫时，每隔1-3min向脱硫罐内加入清水，使废橡胶粉得到持续的湿润，可有效避免废橡胶在搅拌加热的脱硫过程中，局部发生结块、焦烧的情况，从而避免废橡胶因焦烧而产生有毒的烟气，在不影响脱硫橡胶的性能的前提下，是橡胶脱硫加工的过程更加环保。
