| 中文摘要: |
| 研究硫化剂过氧化二异丙苯（DCP）、助交联剂三烯丙基异氰脲酸酯（TAIC）和喷雾炭黑用量等对以四丙氟橡胶为主体材料的耐230 ℃过热水橡胶软管内层胶性能的影响。结果表明：DCP与TAIC并用比为2/5的硫化体系对内层胶交联效果较好，经230 ℃×48 h过热水老化后，硫化胶的物理性能保持良好；喷雾炭黑用量为30份时补强性能最佳，硫化胶的耐过热水性能较好；三氧化二锑无补强作用，但可以降低胶料成本并改善耐过热水性能；1～2份硬脂酸锌作润滑剂对硫化胶的性能影响较小。 |
| 英文摘要: |
| The influence of vulcanizing agent DCP，coagent TAIC and the amount of spray carbon black on the properties of lining compound of rubber hose with 230 ℃ superheated water resistance using tetrapropyl fluoro elastomer as main material was studied．The results showed that the crosslinking effect of lining compound using the vulcanization system with DCP/TAIC amount ratio of 2/5 was better．After 230 ℃×48 h superheated water aging，the retention ratio of the physical properties of the vulcanizate was good．When the amount of spray carbon black was 30 phr，its reinforcement property was the best，and superheated water resistance of the vulcanizate was better．Antimony trioxide had no reinforcing effect，but it could reduce the cost of compound and improve superheated water resistance．1～2 phr zinc stearate as lubricant had little
effect on the properties of the vulcanizate. |
