北京化工大学根据毛细管流变仪的结构特性,模拟工业生产溴化丁基橡胶的螺杆挤出干燥过程,采用溶液法合成了溴含量及其微观结构均符合工业要求的溴化丁基橡胶。考察了150℃和180℃下,改变胶料在毛细管流变仪料筒中的停留时间,溴化丁基橡胶溴含量及其微观结构的变化。结果表明,一定温度下,延长胶料在料筒中的
According to the structural characteristics of capillary rheometer, Beijing University of Chemical Technology simulated the extrusion process of bromobutyl rubber in industrial production. The brominated butyl rubber with bromine content and its microstructure were all synthesized by the solution method. The changes of the residence time of the rubber compound in the capillary rheometer cylinder, the content of brominated brominated butyl rubber and its microstructure were investigated at 150 ℃ and 180 ℃. The results show that, at a certain temperature, extend the rubber in the barrel
