摘　　要：为了研究不同结构的环氧树脂在电子束辐射条件下的辐射化学行为及其对环氧树脂辐射固化行为与性能的影响。通过对环氧树脂电子束辐射前后的粘度变化、加热失重率以及辐射产生的小分子的对比研究发现,各种环氧树脂在电子束辐射下均有不同程度的辐射分解反应发生。其中,以缩水甘油酯型环氧树脂和含酯基的环氧树脂的分解最为严重,缩水甘油胺环氧树脂次之,缩水甘油醚环氧树脂受电子束辐射的降解影响最小。The study was aimed at understanding behaviors of epoxy resins under electron beam irradiation, Epoxy resins of different molecular structures, which include glycidyl ether resin, glycidyl ester resin, glycidyl amine resin, and alicyclic epoxy resin, were irradiated with 5 MeV electron beams. The irradiated samples were investigated with their viscosity changes, weight losses and gaseous molecules generated by the irradiation. The results show that the glycidyl ester resin and the epoxy containing ester group underwent the most serious decomposition bt the irradiation, while the glycidyl amine resin was decomposed less seriously and the glycidyl ether resin was the least decomposed.
