摘　　要：选用了4个硅酮结构密封胶企业的单、双组份共8个样品,模拟自然老化,考察了在热处理加速老化下硅酮结构密封胶的力学性能随老化时间的影响。得出了一些结论,以期为建筑幕墙的耐久性、安全性问题提供一定的技术依据。8 samples of single and double component groups of silicone structure sealant which provided by 4 enterprise was simulated for nature aging process, investigated the effect of silicone structure sealant mechanics property changed with aging time during heat accelerate aging. Some results was obtained and wished to be the technique referents for the duration and safety of curtain wall.

关 键 词：硅酮结构 密封胶 热老化 耐久性
