摘　　要：耐高温环氧胶粘剂通常需要进行升温固化,加温时间对胶粘剂性能有很大影响。采用万能试验机和热重分析仪对一种环氧胶粘剂的加温后处理时间进行研究。结果表明:这种环氧胶粘剂经过1h后处理即可得到优秀的高温性能,并且经过4h后处理后其高温性能具有稳定性。The epoxy adhesive with high temperature resistance usually needs heating to cure,and the heating time has a great influence on its properties.The heating post-treatment time for an epoxy adhesive has been studied with the universal mechanical tester and thermogravimetric analyzer.The research results show that this epoxy adhesive can obtain an excellent high temperature property after the post-treatment for 1h,and the high temperature property tends to be stable when the post-treatment time extends to 4h.
