摘　　要：本文研究了不同含水量对拉挤环氧/酸酐体系理化性能和固化性能的影响。通过旋转流变仪、差式扫描量热仪、万能试验机等测试手段,探究了树脂中不同含水量对环氧/酸酐体系的黏度变化、T_(g)和固化行为的影响,并对环氧树脂浇注体力学性能进行了分析。结果表明:随着环氧树脂体系内含水量的增加,环氧树脂的耐热性能逐渐下降,浇注体力学性能呈现降低的趋势;在含水树脂中添加适量甲基四氢苯酐,可有效降低水分对环氧/酸酐体系固化性能的影响。In this paper,the effects of water content on the physical and chemical properties and curing properties of epoxy resin were studied.Through varions testing methods,such as rotating rotators,differential scanning heat meters,universal testing machine,the effect of different water content on the viscosity,Tg,curing behavior and mechanical properties of the epoxy resin system were explored.The results showed that as the water content in the epoxy resin system increased,the heat resistance of epoxy resin gradually decreased,and the mechanical performance of casting decreased.Adding modest doses of MTHPA to the aqueous resin can reduce the negative effect on the curing performance of the epoxy-anhydride system impact of water content.
