摘　　要：本文对环氧树脂体系(EP)与加入纳米氢氧化铝(Nano-ATH)的环氧树脂体系进行了固化动力学研究,用n级反应模型分析了一系列差示扫描量热法(DSC)的试验数据,计算出了两个体系的反应活化能分别为63.15kJ/mol和66.43 kJ/mol,反应级数均为一级反应。并对两个体系的玻璃化转变温度(Tg)作了比较。研究结果表明:加入Nano-ATH的树脂体系活化能得到提高,Tg升高约12℃,具有更好的耐热性。The epoxy resin system filled with Nano - ATH was researched on curing kinetics. A series of testing data by DSC was analyzed by n scale reaction model. The reaction activation energy for two systems was computing as 63.15 k.l/mol and 66.43 kJ/mol and the reaction scaling is first level. Meanwhile,the glass transition temperature （ Ts ）for the two systems was compared. The results show that the activation energy was improved and Tg was elevated to 12℃ ,besides ,having a better heat resistance for the system filled with Nano - ATH.
