摘要:
选取了具有不同微观结构的氯化丁基橡胶(CIIR),研究了微观结构和硬脂酸钙含量对其硫化特性、物理机械性能及耐热老化性能的影响。结果表明,随着CIIR氯代外仲位烯丙基结构含量的增加,其硫化速率加快;随着硬脂酸钙含量的增加,其正硫化时间延长,硫化胶交联密度降低,耐热老化性能变差;当门尼应力松弛斜率越大时,产品的收缩率就越小,说明其尺寸稳定性和加工性能越好。
Abstract:
Several chlorinated butyl rubbers (CIIR) with different microstructures were selected to study the effects of microstructure and calcium stearate content on their vulcanization characteristics, physical and mechanical properties and heat aging resistance. The results showed that the curing rate was accelerated with the increase of the content of chlorinated secondary allyl group structure of CIIR. With the increase of calcium stearate content, the optimum curing time was prolonged, the crosslinking density of CIIR compound decreased and the heat aging resistance became worse. The larger the Mooney stress relaxation slope was, the smaller the shrinkage of the product was, which indicated that the product had the better dimensional stability and processing performance.
