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并用胶的耐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。
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.
