中文摘要:
      对比研究白炭黑补强国产稀土异戊橡胶（IR）与天然橡胶（NR）的硫化特性、物理性能及动态力学性能。结果表明：与NR胶料相比，填充等量白炭黑的IR胶料的ts1和t90缩短，ML和MH减小；硫化胶的定伸应力和拉伸强度减小，拉断伸长率增大；当白炭黑用量为30份时，IR硫化胶的Payne效应最明显，剪切储能模量增大，剪切损耗模量减小，损耗因子增大，白炭黑在IR中的分散较差。
英文摘要:
      The curing characteristics， physical properties and dynamic mechanical property of the silica filled domestic rare earth IR and NR compounds were investigated.The results showed that，compared with NR compound， the ts1 and t90 of the IR compound filled with equal weight silica were shorter，and the ML and MH were lower.The modulus and tensile strength of the IR vulcanizates were lower than that of NR vulcanizates，and the elongation at break was higher.When the addition level of silica was 30 phr，the Payne effect of IR vulcanizates was the most pronounced，while the shear storage modulus increased，shear loss modulus decreased，loss factor increased，and the dispersion of silica in IR was poor.
