环氧树脂/BPEA-2潜伏性固化体系固化物的热行为研究

On the thermal action of cured epoxy resin/ BPEA-2 latent curing system

采用热膨胀仪、差式扫描量热分析仪（ Ｄ Ｓ Ｃ） 、热重分析仪（ Ｔ Ｇ） 等方法对 Ｂ Ｐ Ｅ Ａ － ２／ Ｃ Ｙ Ｄ１２８ 潜伏性固化体系的固化物的热稳定性及热形变进行了研究结果表明：体系固化物的热变形温度与固化剂的用量有一定的关系，固化物的热稳定性良好，其初始分解温度在３００ ℃左右，快速分解温区在３００ ～４８０ ℃之间， 体系固化物的热降解活化能约为１６１ ．３ｋ Ｊ／

The thermal action of cured BPEA-2/CYD-128 latent curing system was studied by DSC ,TG. The results showed that the thermal deformation temperature of cured system was influent by the content of curing agent, the thermal stability was good and the initial thermal decomposition temperature was about 300℃,the cured system decomposed fast at 300～480℃. The thermal decomposition active energy was about 161.3 kJ/mol
