| 中文摘要: |
| 研究炭黑氧化度对顺丁橡胶（BR）/天然橡胶（NR）并用胶性能的影响。经高温脱挥或氧化处理后炭黑填充的BR/NR并用胶的门尼粘度增大，加工性能变差；与未处理的炭黑填充BR/NR并用胶相比，高温脱挥处理炭黑填充BR/NR并用胶的300%定伸应力、拉伸强度和压缩疲劳温升提高，耐老化性能降低；随着炭黑氧化度的增大，BR/NR并用胶的300%定伸应力、拉伸强度、撕裂强度和压缩疲劳温升降低；随着炭黑挥发分含量和氧化度的减小，0和60 ℃时BR/NR并用胶的损耗因子增大。 |
| 英文摘要: |
| The effect of carbon black oxidation degree on the properties of butadiene rubber（BR）/natural rubber（NR） blends was studied.The Mooney viscosity of BR/NR blend filled with carbon black after treatment by high-temperature devolatilization or oxidation increased，and the processing performance deteriorated.Compared with untreated carbon black filled BR/NR blends，the high temperature devolatilization treated carbon black filled BR/NR blends showed an increase in modulus at 300% elongation，tensile strength and compressive fatigue temperature-rise increased，while the aging resistance decreased.As the oxidation degree of carbon black increased，the 300% tensile stress，tensile strength，tear strength and compressive fatigue temperature-rise of BR/NR blend decreased.As the volatile content and oxidation degree of carbon black decreased，the loss factor of BR/NR blend increased at 0 and 60 ℃. |
