| 中文摘要: |
| 研究5种炭黑（RX2007，NC1301，NC1312，BC2109，N234）填充的天然橡胶（NR）/顺丁橡胶（BR）并用胶的性能。结果表明，炭黑RX2007填充的NR/BR并用胶的t90最短，炭黑NC1312填充的NR/BR并用胶的t90最长；炭黑BC2109和N234填充的NR/BR并用胶的定伸应力、拉伸强度和撕裂强度较大；炭黑RX2007填充的NR/BR并用胶的动态力学性能最优；炭黑RX2007和N234填充的NR/BR并用胶的抗压缩疲劳生热性能较优；炭黑NC1312填充的NR/BR并用胶的耐磨性能最佳；5种炭黑在NR/BR基体中均分散良好，炭黑各项物性综合决定炭黑填充的NR/BR并用胶的各项性能。 |
| 英文摘要: |
| The properties of natural rubber （NR）/butadiene rubber（BR） blends filled with five kinds of
carbon black（RX2007，NC1301，NC1312，BC2109，and N234）were studied. The results showed that all five
kinds of carbon black were well dispersed in the NR/BR matrix and the properties of NR/BR blend highly
depended on the physical properties of the filled carbon black. It was found that the t90 of the NR/BR blend
filled with carbon black RX2007 was the shortest，and the t90 of the NR/BR blend filled with carbon black
NC1312 was the longest. The modulus，tensile strength and tear strength of the NR/BR blends filled with
carbon black BC2109 and N234 were higher. The dynamic mechanical properties of the NR/BR blend filled
with carbon black RX2007 were the best. The compression fatigue heat build-up resistance of the NR/BR
blends filled with carbon black RX2007 and N234 was better. The wear resistance of the NR/BR blend filled
with carbon black NC1312 was the best. |
