| 中文摘要: |
| 研究混炼工艺对溴化丁基橡胶（BIIR）胶料硫化特性稳定性的影响。结果表明：终炼时使用双台开炼机的胶料硫化特性稳定性优于使用单台开炼机的胶料；增加终炼回炼工艺，胶料的硫化特性稳定性提高，正硫化时间稍有缩短，但符合工艺要求；调整氧化锌和硬脂酸的加料顺序对胶料硫化特性稳定性的改善作用不明显；不同混炼工艺方案胶料的工艺性能均较好，胶料在后续工序中使用未出现异常。BIIR胶料终炼采用双开炼机并结合终炼回炼工艺，可以改善胶料的硫化特性稳定性，但需要关注胶料t90的变化。 |
| 英文摘要: |
| The influence of the mixing process on the stability of vulcanization characteristics of brominated butyl rubber（BIIR） compound was studied. The results showed that，by using double mills in the final mixing stage，the vulcanization stability of the compound was better than that using single mill. The vulcanization stability of the compound could also be improved by further reprocessing，the optimum cure time was shortened，but it still met the processing requirements. The effect of additive sequences of zinc oxide and stearic acid on the vulcanization stability was not significant. The processing performance of the compounds with different mixing process was good and normal in the follow-up process. It was concluded that the BIIR compounds possessed a good vulcanization stability when double mills were used and remixing step was added，while the change of the optimum cure time should be carefully controlled. |
