| 摘 要： | 研究顺丁橡胶(BR)/天然橡胶(NR)并用比对并用胶性能的影响,并将并用胶用于隔震橡胶支座,考察其对隔震橡胶支座力学性能及温度相关性的影响。结果表明:与NR胶料相比,BR/NR并用胶的加工性能更优,耐低温性能更好,热空气老化性能基本不变,拉伸强度和撕裂强度随着BR/NR并用比的增大逐渐减小;NR与BR并用对隔震橡胶支座的力学性能不利,对温度相关性有利。

| Abstract: | The effects of butadiene rubber(BR)/natural rubber(NR) blend ratio on the properties of the blend were studied. The blend was used in rubber isolation bearings and the effect of the blend on the mechanical properties and temperature dependence of the bearings was also investigated. The results showed that,compared with NR compound,BR/NR blend had better processability and low temperature resistance, hot air aging performance was similar,and the tensile strength and tear strength gradually decreased with the increase of BR/NR blend ratio. Combination of NR and BR was unfavorable to the mechanical properties of rubber bearings but favorable to the temperature dependence. |
