摘　　要：以不同工艺制备了溴化丁基再生胶(BIIR再生胶),并将其应用于三角带加热胶套和胶板中部分替代溴化丁基橡胶(BIIR)或三元乙丙橡胶(EPDM),研究了再生橡胶替代量及硫化体系对三角带加热胶套及胶板性能的影响。结果表明,并用少量BIIR再生胶对制品混炼胶的硫化特性影响不大。密炼再生制备的BIIR再生胶在胶套中的最佳替代量为5份,此时胶套硫化胶的物理性能及老化性能优异。开炼机再生制备的BIIR再生胶在胶板中应用最佳并用质量比为20/80(再生胶/EPDM),硫化体系为二-(叔丁基过氧化异丙基)苯(DCP)硫化,此时共混胶性能最佳。因此,再生胶的应用既能保证胶套、胶板制品性能不下降,还能降低原材料的成本及生产的能耗,废胶套再生及再生胶应用具有重要的现实意义。In this paper,waste brominated butyl rubber was regenerated by using different regeneration technology.And raw rubber was partly replaced by brominated butyl reclaimed rubber in rubber sleeves and rubber slabs for the vulcanization of triangle conveyer belt.The effects of brominated butyl reclaimed rubber,vulcanization system on the mechanical properties of rubber sleeves and rubber slabs were also studied.The results showed that the application of brominated butyl reclaimed rubber can save material costs and energy consumption,and yet not have any degraded performance.For this reason,the regeneration of waste rubber sleeves and the application of the reclaimed rubber could have important practical significance.
