| 中文摘要: |
| 研究三元乙丙橡胶（EPDM）防水卷材的耐热氧老化性能。结果表明：经过热氧老化，EPDM硫化胶的硬度、拉伸强度、交联密度总体呈增大趋势；过氧化物体系硫化胶料的老化因数都大于1，且随着老化时间的延长，老化因数变化很小；半有效硫黄硫化体系硫化的EPDM胶料的接触角随老化时间延长先增大后减小，过氧化物体系硫化的EPDM胶料的接触角随老化时间延长先增大后减小然后再增大。 |
| 英文摘要: |
| The thermal oxidative aging resistance of ethylene-propylene-diene Monome（EPDM） waterproofing membrane was studied.The results indicated that after thermal oxygen aging，the hardness，tensile strength and crosslinking density of EPDM vulcanizate showed an overall increasing trend.The aging coefficients of peroxide system vulcanized compound were all greater than 1，and with the extension of aging time，the aging coefficient changed very little.The contact angle of EPDM compound with semi effective sulfur vulcanization system increased first and then decreased with aging time，while the contact angle of EPDM compound with peroxide system vulcanization increased first，then decreased，and then increased again with aging time. |
