| 中文摘要: |
| 本文采用不同量的高乙烯基聚丁二烯橡胶(HVBR)作为助交联剂,用过氧化二异丙苯引发交联四丙氟橡胶(FEPM)制备具有新形交联结构的HVBR/FEPM共混橡胶,同时表征了该类橡胶的硫化特性、力学性能、断面形貌、溶胀度和热性能。结果表明：随着HVBR含量的增加,共混胶的拉伸强度及硬度增加,拉断伸长率降低,加工安全性和流动性均变优；共混胶的玻璃化转变温度与FEPM的接近,并HVBR用量的增大,玻璃化转变温度提高,同时,随HVBR用量的增大,共混胶的耐热性能提高。 |
| 英文摘要: |
| By using different ratio of high vinyl polybutadiene(HVBR) as auxiliary crosslinking agent together with dicumyl peroxide as main crosslinking to trigger tetrafluoroethylene-propylene rubber(FEPM) to prepare new crosslinking structure of HVBR/FEPM rubber. And characterizing its properties of vulcanization, mechanical properties, fracture morphology, swelling degree and thermal property. The results showed that, the tensile strength and hardness of the composites increased and process safety and liquidity are optimal while the elongation decreased as the addition of HVBR. Its glass-transition temperature is close to that of FEPM, and its glass-transition temperature increased and its thermal property improved as the addition of HVBR. |
