| 中文摘要: |
| 研究与60份炭黑N660相比，15份废旧轮胎裂解炭黑（CBp）/45份炭黑N660并用对轮胎溴化丁基橡胶（BIIR）气
密层胶性能的影响。结果表明：与炭黑N660相比，CBp的灰分含量和筛余物含量大，DBP吸收值略小；与60份炭黑N660
填充的BIIR胶料相比，15份CBp/45份炭黑N660并用填充的BIIR胶料的硫化特性变化不大，拉断伸长率减小，300%定伸
应力和拉伸强度增大，耐热空气老化性能无明显变化，气密性相当，即采用15份CBp替代15份炭黑N660的BIIR气密层胶
在保证使用性能的前提下，有效降低了生产成本。 |
| 英文摘要: |
| The effect of 15 phr waste tire pyrolysis carbon black（CBp）/45 phr carbon black N660
blending on the properties of the bromobutyl rubber（BIIR） inner liner compound of tire was studied and
compared with 60 phr carbon black N660. The results showed that，compared with carbon black N660，CBp
had larger ash content and larger sieve residue content and slightly smaller DBP absorption value. Compared
with the BIIR compound filled with 60 phr carbon black N660，the vulcanization characteristics of the BIIR
compound filled with 15 phr CBp/45 phr carbon black N660 blend had little change，the elongation at break
decreased，the tensile stress at 300% elongation and tensile strength increased，the hot air aging resistance had
no obvious change，and the air tightness was equivalent. Therefore，with 15 phr CBp replacing 15 phr carbon
black N660 in the BIIR inner liner compound，the production cost was effectively reduced under the premise
of ensuring performance. |
