This study examined the effect of recycled carbon-based material (rCBM), obtained by chemical degradation of end-of-life tires, on the mixture of tire tread (rubber composite) by comparing it with commercial carbon black (CB-N550). The new chemical degradation method was defined and the new rCBM was obtained. This newly method is more advantageous than other methods (devulcanization and pyrolysis). The rheometeric properties, mechanical properties, hardness, morphological properties, functional structures, thermal degradation behaviours of the rubber composites prepared were determined. The total number of bonds decreased as the amount of rCBM increased in the rubber composite mixture. As the vulcanized rubber network of the rCBM-filled rubber decreases, the cross-linking density of the rCBM-filled rubber was also reduced. As rCBM has a high sulfur value, the degree of chemical cross-linking of rCBM was reduced. In conclusion, rCBM will not be used in place of commercial carbon black but may be used by mixing with commercial carbon black depending on the desired properties of the end products.

这项研究通过将报废轮胎的化学降解获得的再生碳基材料（rCBM）与商用炭黑（CB-N550）进行比较，研究了其对轮胎胎面（橡胶复合材料）混合物的影响。定义了新的化学降解方法并获得了新的rCBM。这种新方法比其他方法（脱硫和热解）更具优势。测定了所制备的橡胶复合材料的流变性能，机械性能，硬度，形态性能，功能结构，热降解行为。随着橡胶复合混合物中rCBM含量的增加，键的总数减少。随着rCBM填充橡胶的硫化橡胶网络减少，rCBM填充橡胶的交联密度也降低。由于rCBM具有高硫值，因此rCBM的化学交联度降低。总之，rCBM将不会代替商用炭黑使用，但可以根据最终产品的所需性能与商用炭黑混合使用。
