| 本文研究分析了废轮胎热解炭黑(CBP)在天然橡胶(NR)中的应用情况,考察了CBP对天然橡胶混炼胶的门尼粘度、硫化特性及其对硫化胶的物理机械性能、磨耗性能、屈挠疲劳性能的影响,并与炭黑N220、N330、N660、N774进行了对比分析。结果表明,CBP聚集体粒径分布宽,并且其灰分含量远高于普通炭黑；NR中加入CBP后,硫化胶的拉伸强度和撕裂强度很高,甚至超过了N220的拉伸强度和撕裂强度,但是加入CBP的硫化胶的100%和300%定伸应力特别低；加入CBP硫化胶的磨耗性能和屈挠疲劳性能都比加普通炭黑的差。 |

| The fundamental characteristics and its application of pyrolytic carbon black (CBP) from waste tires were studied. The effects of CBP on Mooney viscosity, the curing characteristics of natural rubber (NR) compounds and the mechanical properties of NR vulcanizates were investigated and compared with other fillers such as carbon N220、N330、N660、N774. The results showed that, the aggregate particle size distribution of CBP was wide, and its ash content was much higher than conventional carbon black. With the incorporation of CBP into NR, tensile strength and tear strength of vulcanized rubber was very high, even more than the tensile strength and tear strength of the N220, while the stress at 100% and 300% was very low; the abrasion resistance and flexing fatigue resistance of CBP was inferior to those conventional carbon black. |
