| 中文摘要: |
| 研究裂解炭黑（CBp）/炭黑N330并用对天然橡胶（NR）胶料性能的影响。结果表明：炭黑N330的比表面积大于CBp，灰分含量明显小于CBp，CBp与炭黑N330的含碳官能团种类及含量差别不大；单一填料硫化胶的表面粗糙度比并用填料硫化胶小，50份炭黑N330硫化胶的表面粗糙度大于50份CBp硫化胶；随着CBp/炭黑N330并用比的增大，胶料的结合胶含量减小，储能模量在小应变下减幅较大，硫化胶的交联密度、邵尔A型硬度、定伸应力和撕裂强度减小，拉断伸长率和回弹值增大，拉伸强度无明显变化，耐磨性能变差。 |

| The effect of of cracked carbon black（CBp）/ carbon black N330 blending on the properties of natural rubber（NR） compound were investigated.The results showed that the specific surface area of carbon black N330 was larger than that of CBp，the ash content was significantly lower than that of CBp，and there was not much difference in the types and contents of carbon functional groups between CBp and carbon black N330.The surface roughness of the vulcanizate with single filler was smaller than that of the vulcanizate with blending fillers，and the surface roughness of the vulcanizate with 50 phr of carbon black N330 was larger than that of the vulcanizate with 50 phr of CBp.As the CBp/carbon black N330 blending ratio increased，bound rubber content of the compound decreased，the storage modulus decreased significantly under small strain，and the crosslinking density，Shore A hardness，tensile stress at given elongation and tear strength of the vulcanizates decreased，while the elongation at break and rebound value increased，the tensile strength changed little，but the wear resistance deteriorated. |
