1·Besides the scorch time and optimum cure time of BIIR were shortened considerably while its curing rate increased obviously.

与丁基橡胶相比，BIIR焦烧时间和正硫化时间明显缩短，硫化速度大大提高。

2·With the increasing of cure temperature, the scorch time and optimum cure time decreased, but the crosslink density had a tread of decreasing.

硫化温度的提高会缩短焦烧时间和正硫化时间，但有使交联密度下降的趋势。

3·The results showed that the Mooney scorch time of rubber compound reduced as the addition level of reclaimed IIR increased, but the physical properties changed little;

结果表明，随着再生IIR用量的增大，胶料的门尼焦烧时间逐渐缩短，物理性能变化不大；

4·The test results showed that the scorch time of rubber compound ex tended by adding nano-zinc oxide, and the tensile strenght, abrasion resistance a nd aging property of its vulcanizate improved;

试验结果表明，纳米氧化锌可延长胶料的焦烧时间，提高硫化胶的拉伸性能和耐磨性能，硫化胶的耐老化性能也较好；
