| 中文摘要: |
| 通过正交试验法分别研究了过氧化二异丙苯(DCP)/N, N"-间苯撑双马来酰亚胺(HVA-2)并用比例、炭黑N550用量和石蜡油用量三个因子对三元乙丙橡胶(EPDM)常温23℃和高温150℃压缩永久变形的影响。结果表明：在试验范围内,配方中影响常温和高温压缩永久变形的主要因子并不同。对于常温压缩永久变形,石蜡油用量对其影响显著；对于高温压缩永久变形,DCP/HVA-2并用比例对其影响显著；无论是常温还是高温压缩永久变形,N550用量对其影响都不显著。 |
| 英文摘要: |
| The effects of dicumyl peroxide (DCP)/N, N’-m-phenylene dismaleimide (HVA-2) ratio, carbon black N550 amount and paraffin oil amount on the compression set of ethylene propylene diene monomer (EPDM) at 23℃ and 150℃ were studied by orthogonal test, respectively. In the experimental range, the results indicated that the major influence factor of the compression set at room temperature and high temperature was different. The paraffin oil amount had a significant effect on the compression set at room temperature. The DCP/HVA-2 ratio had a significant effect on the compression set at high temperature. But the N550 amount had less effect on both the compression set at room and high temperature. |
