摘　　要：以聚醚胺类化合物作为环氧树脂的固化剂,得到的固化体系相对脂肪胺及简单二胺为固化剂的固化体系具有良好的弯曲强度和抗冲击性能。并采用DSC测试方法研究了环氧树脂与聚醚胺的固化进程动力学参数,由Kissinger方程得出固化反应的活化能E为51.91kJ/mol,频率因子A为3.214×106 s-1,由Crane方程得出固化反应级数n=0.887 9,并得到固化反应的动力学方程,-dα/dt=k(1-α)0.887 9,其中k=3.214×106exp(-6 243.7/T)。Epoxy resin were cured with polyether amines and simple diamines and aliphatic amines.The results indicated that the bending modulus and the impact toughness of the former were higher.The curing process kinetics and material properties of epoxy resin and polyether amines were studied by DSC.The energy of activation（E） was 51.91 kJ/mol and frequency factor（A） was 3.214×106 s-1 via the Kissinger method.According to Crane theory the reaction order（n=0.887 9） was calculated.Dynamic equation of curing reaction was found to be-dα/dt=k（1-α）0.887 9,which k=3.214×106exp（-6 243.7/T）.
