| 研究裂解炭黑（CBp）在全钢载重子午线轮胎胎面胶中的应用。结果表明：41.2份CBp和8.8份白炭黑1165替代35份炭黑N660和15份白炭黑1165的混炼胶的门尼粘度最大，50份CBp替代35份炭黑N660和15份白炭黑1165的混炼胶的 t10和t90最短；46.7份CBp和3.3份白炭黑1165与50份CBp替代35份炭黑N660和15份白炭黑1165的混炼胶的G′和ΔG′相当，且ΔG′较大；43.7份CBp和6.3份白炭黑1165替代35份炭黑N660和15份白炭黑1165的硫化胶的300%定伸应力最大；35份CBp替代35份炭黑N660的硫化胶的拉伸强度和拉断伸长率最大；50份CBp替代35份炭黑N660和15份白炭黑1165的硫化胶的磨耗量最小，0 ℃和60 ℃时的tanδ均最大，团聚体区域占比最大，填料分散性最差。 |

| The application of pyrolysis carbon black （CBp）in tread compounds of all-steel truck and bus radial （TBR） tires was studies.The results showed that replacing 35 phr of carbon black N660 and 15 phr of silica 1165 with 41.2 phr of CBp and 8.8 phr of silica 1165 resulted in the maximum Mooney viscosity of the compound，replacing 35 phr of carbon black N660 and 15 phr of silica 1165 with 50 phr of CBp resulted in the shortest t10and t90 of the compound.Replacing 35 phr of carbon black N660 and 15 phr of silica 1165 with 46.7 phr of CBp and 3.3 phr of silica 1165 and with 50 phr of CBp resulted in comparable G′ and ΔG′of the compound，and ΔG′ was larger.Replacing 35 phr of carbon black N660 and 15 phr of silica 1165 with 43.7 phr of CBp and 6.3 phr of silica 1165 resulted in the maximum 300% modulus of the vulcanizate.Replacing 35 phr of carbon black N660 with 35 phr of CBp resulted in the maximum tensile strength and elongation at break of the vulcanizate.Replacing 35 phr of carbon black N660 and 15 phr of silica 1165 with 50 phr of CBp resulted in the minimum wear volume of the vulcanizate，the maximum tanδ at 0 °C and 60 °C，and the largest proportion of agglomerate areas，with the worst dispersion of the filler. |
