| 中文摘要: |
| 研究炭黑N660/裂解炭黑并用对溴化丁基橡胶（BIIR）气密层胶性能的影响。结果表明：裂解炭黑粒径大于炭黑N660；随着裂解炭黑用量的增大，胶料的门尼粘度提高，t10和t90总体延长，加工安全性能较好，硫化速度较慢；与纯炭黑N660胶料相比，添加裂解炭黑的胶料物理性能总体降低，炭黑N660/裂解炭黑并用比为40/20的胶料综合物理性能较好，成本降低；炭黑N660/裂解炭黑并用胶料的耐热氧老化性能和气密性较好。 |
| 英文摘要: |
| The effect of carbon black N660/pyrolysis carbon black blend on the properties of brominated butyl rubber（BIIR） inner liner compound was studied. The results showed that the particle size of pyrolysis carbon black was larger than that of carbon black N660. With the amount of pyrolysis carbon black increasing，the Mooney viscosity of the compound increased，t10 and t90 were generally prolonged，the processing safety performance was better，and the curing speed was slower. Compared with the compound filled with only carbon black N660，the physical properties of the compound with the addition of pyrolysis carbon black were generally reduced. The comprehensive physical performance of the compound with carbon black N660/pyrolysis carbon black with 40/20 blend ratio was good，and the performance to cost ratio was better. The compound filled with carbon black N660/pyrolysis carbon black had better thermal oxidative aging resistance and air tightness. |
