| 摘 要： | 研究了环氧/铝胶接接头在35℃、55℃、质量分数为5%的氯化钠水溶液中的老化行为,同时与其在水中的老化行为进行了对比,并用扫描电镜(SEM)和傅里叶红外光谱仪(FTIR)分析了其在氯化钠水溶液中失效的机理。结果表明,提高温度可以加速环氧胶接接头在氯化钠水溶液中的老化;环氧胶接接头在氯化钠水溶液中的老化速度比其在水中的老化速度快;环氧胶接接头在氯化钠水溶液中破坏失效的原因主要是氯化钠水溶液促进了环氧胶粘剂的水解。

| Abstract: | The aging behavior of epoxy/Al adhesive joint at 35 ℃ and 55 ℃ in 5wt% sodium chloride aqueous solution was investigated and compared with that of in water.The failure mechanism in sodium chloride aqueous solution was analyzed by SEM and FTIR.The results showed that the aging of epoxy adhesive joint in sodium chloride aqueous solution was accelerated by raising the temperature.The aging rate of epoxy adhesive joint in sodium chloride aqueous solution was faster than that of in water.The main reasons for the failure of epoxy adhesive joint in sodium chloride aqueous solution was the sodium chloride aqueous solution promoted the hydrolyzation of epoxy adhesive. |
