中文摘要: |
对IIR/EPDM并用胶性能进行试验研究。结果表明,在EPDM用量不超过30份时,随着EPDM用量的增大,IIR/EPDM并用胶的加工性能、焦烧时间和硫化速度变化不大;与IIR硫化胶相比,IIR/EPDM并用胶的交联密度减小,拉伸强度和拉断伸长率增大,撕裂强度略有提高,长期耐热老化性能相当,-10~25 ℃时的损耗因子小于IIR硫化胶,25~200 ℃时的损耗因子大于IIR硫化胶。 |
英文摘要: |
The properties of IIR/EPDM blend were experimentally investigated.The results showed that the processibility,scorch time and curing rate changed little as the addition level of EPDM increased up to 30 phr;and when compared to IIR vulcanizate,IIR/EPDM vulcanizate possessed lower cross-link density,higher tensile strength and elongation at break,a little higher tear strength,similar thermal aging property,smaller tanδ at -10~+25 ℃ and greater tanδ at 25~200 ℃. |
