| 中文摘要: |
| 探讨热处理温度对裂解炭黑（CBp）性能的影响及热处理CBp在天然橡胶（NR）胶料中的应用。结果表明：在350～550 ℃热处理温度下，随着热处理温度的升高，CBp的比表面积和甲苯抽出物透光率指标明显增大，理化性能变好；热处理CBp填充胶料的门尼粘度增大，t10和t90缩短；随着CBp的热处理温度的升高，其填充硫化胶的300%定伸应力和撕裂强度先增大后减小，压缩疲劳温升先降低后升高，热处理温度为450 ℃的CBp填充硫化胶的300%定伸应力最大，为7.38 MPa；热处理CBp填充硫化胶的回弹值和拉断伸长率增大。 |

| The effect of heat treatment temperatures on the properties of the pyrolytic carbon black （CBp） and its application in natural rubber（NR） compound were studied.The results showed that at treatment temperatures ranging from 350 to 550 ℃，the specific surface area and toluent extract transmittance of CBp significantly increased with the rising of the temperature，indicating improvement in its physicochemical properties.The Mooney viscosity of the compound filled with heat treatment CBp increased，while the scorch time and vulcanization time shortened.As the heat treatment temperature of CBp increased，the 300% modulus and tear strength of the CBp filled vulcanizate first increased and then decreased，the compression fatigue temperature rise initially decreased and then increased，the CBp filled vulcanizate with a heat treatment temperature of 450 ℃ exhibited the highest 300% modulus of 7.38 MPa.The rebound value and elongation at break of the vulcanizate filled with the heat treated CBp increased. |
