| 中文摘要: |
| 研究了金属氧化物(二氧化锡、三氧化二铁和铁锡氧化物复合物)对单组分缩合型室温硫化氟硅橡胶(FR1)耐热空气老化性能的影响。结果表明，二氧化锡、三氧化二铁和铁锡氧化物复合物能提高FR1的耐热空气老化性能，使FR1的初始分解温度分别提高15，15和30 ℃，并使FR1的热重曲线向高温方向偏移；二氧化锡和三氧化二铁在耐热空气老化方面有协同作用，铁锡氧化物复合物的耐热空气老化性能最好。 |

| The influence of metallic oxides，such as ferric oxide，stannic oxide and their complexes on the hot air aging property of one-pack RTV fluorosilicone rubber (FR1) was studied.The results showed that the hot air aging property of FR1 improved，the curve of FR1 in TG-TDA shifted towards the high temperature region，the initial decomposition temperature of FR1 compounds raised by 15，15 and 30 ℃ respectively by using stannic oxide，ferric oxide or their complex；the blend of stannic oxide and ferric oxide possessed a synergistic effect and their complex had the best effect. |
