摘　　要：本文采用差示扫描量热(DSC)法研究了QY891-Ⅱ改性双马树脂的固化反应动力学,利用Kissinger方程和Crane方程分别得到了该树脂固化反应表观活化能E、表观频率因子A和反应级数n,进而提出了该树脂固化成型过程的动力学模型,通过固化反应动力学模型对固化反应特性进行了预测,为改性双马树脂实际应用中固化工艺参数的进一步优化提供了一定的理论参考依据。In this paper, the kinetics of curing reaction of QY891 - Ⅱ modified bismaleimide is studied by differential scanning calorimetry （DSC）. By using Kissinger equation and Crane equation to get the kinetic parameter of curing reaction of the modified BMI resin, such as the overall activation energy, the frequency factor and the value of reaction order（n）, the kinetics model of the curing process is set up. On basis of the model, we can predict characteristics of the curing reaction and determine reasonable curing process parameter of the resin.
