摘要
研究了共混比对氯丁橡胶/聚氨酯橡胶(CR/PUR)的硫化特性,硫化胶力学性能、耐热老化性能以及高温压缩永久变形的影响。结果表明,CR与PUR共混,可以提高PUR的硫化速度。当CR/PUR共混比在10/90～15/85时,共混物具有较好的力学性能、耐热老化性能及压缩永久变形性能。
In this paper, the influence of the ratio of the CR/PUR blends on the curing characteristic,mechanical property,hot ageing resistance and thermo compression set of the blends were studied. The results showed that the blends of CR/PUR could increase the velocity of PUR＇s vulcanization. When the ratio of CR/PUR blends varied from 10/90 to 15/85 ,the blends would hold a good mechanical property,hot ageing resistance and compression set
