摘　　要：采用非等温DSC方法研究了FMRE／DDS固化反应体系的反应动力学。根据Kissinger方法和Ozawa方法计算了固化反应体系的两个反应动力学参数活化能和反应级数。通过反应级数可知，FMRE与DDS固化反应是个复杂的化学反应。两种非等温动力学方法计算的固化反应活化能中，Ozawa方法计算的活化能值略高于Kissinger方法计算的活化能值。由热失重分析和差热分析可知，FMRFMHHPA固化物和FMRE／DDS固化物均具有较好的热性能。Cured reaction kinetics of FMRE/DDS system was studied by the use of non-isothermal DSC. According to the methods of Kissinger and Ozawa, two kinetic parameters, activation energy and reaction order, of cured reaction system were calculated. From the reaction order, the cured reaction of FMRFMDDS is complex chemical reaction. FMRE was cured with different kinds of cured agents. By DSC and TGA, the two kinds of cured products have better thermal properties.
