| Abstract: |
| 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. |
