交联溴化丁基橡胶的再生研究

Research of the Regeneration of Waste Cross-linked Brominated Butyl-Rubber

采用天然再生剂大蒜汁并结合开炼、密炼等再生方法对废溴化丁基橡胶的再生情况进行探讨。结果表明:开炼温度、开炼时间、密炼温度、密炼时间及再生剂用量对再生效果均有影响,且在这些因素中,再生剂为主导因素。在开炼温度为55℃、开炼时间为10min、加入再生剂用量为6%时再生效果最佳;密炼温度为125℃、密炼时间10min、再生剂用为6%时取得最佳再生效果。

The waste cross-linked brominated butyl-rubber was regenerated with the garlic juice by mixing and banburying in this paper.The result showed that：The factors influence the regenerated rubber properties were discussed,such as the temperature and time of mixing and banburying,the dosage of the garlic juice and so on.Among these factors the dosage of garlic juice was the main factor.When the cross-linked brominated butyl-rubber was regenerated with garlic juice by mixing,the optimal temperature was 55℃,the time was 10 minutes,and the dosage of garlic juice was 6%.When the cross-linked brominated butyl-rubber was regenerated with garlic juice by banburying,the optimal temperature was 125℃,the time was 10 minutes,and the dosage of garlic juice was 6%.
