| 中文摘要: |
| 探讨生胶并用比、硫黄用量、促进剂用量、补强剂种类和用量、软化剂用量对EPDM/IIR并用胶硫化特性的影响。结果表明，EPDM/IIR并用比增大，并用胶的t90缩短，MH增大；硫黄用量增大，并用胶的t10缩短，t90延长，MH增大；促进剂CZ用量增大对并用胶的硫化特性无明显影响； 炭黑N220作补强剂的并用胶t10和t90较短，MH较大；炭黑N220用量增大，并用胶的t90延长，ML和MH增大； 软化剂凡士林用量增大，并用胶的t90缩短，MH减小。 |
| 英文摘要: |
| The effect of the polymer blending ratio，the filler type，and the sulfur，accelerator，filler and softener levels on the curing behaviour of EPDM/IIR blend was investigated.The results showed that the t90 shortened and the maximum torque MH increased as the blending ratio of EPDM/IIR increased；t10 shortened，t90 extended and MH increased as the sulfur level increased；the increase of CZ level had little effect on the curing behaviour of blend；for the N220 filled blend，t10 and t90 were shorter，but MH was greater；t90 extended and both minimum torque ML and MH increased as the N220 level increased；and t90 shortened and MH decreased as the level of softener vaseline increased. |
