摘　　要：通过交联溴化丁基橡胶与聚丙烯的共混改性,使得交联的溴化丁基橡胶具有较好的机械性能以及加工性能,本文研究了共混比、相容剂用量、开炼温度、开炼时间、硫化温度等相关工艺条件。结果表明在橡塑共混比为3:1,相容剂用量为总质量的7%,开炼温度与时间为150℃、10min,硫化温度为170℃时,可获得综合性能较好的共混胶料。In the interest of fine mechanical properties and processing performance,the crosslinked bromobutyl rubber was modified by blend with the polypropylene in this paper.The blend ratio of the crosslinked bromobutyl rubber and the polypropylene,the dosage of inosculating reagent,the mixing temperature,the mixing time,vulcanization temperature,and other related conditions were researched.The result show that:the optimal blend ratio was 3:1 in the rubber blend,the dosage of inosculating reagent was 7% of the mass percent,the mixing temperature and time were 150℃ and 10min,the vulcanization temperature is 170℃.the obtained blend rubber was material with better integration performance.
