中文摘要：

通过非等温示差量热扫描仪（DSC）研究了苯并噁嗪／核壳橡胶（Ba／CSR）体系动态固化行为。利用Kissinger、Ozawa和Crane法研究了固化反应动力学，求得固化反应的动力学参数。结果表明，复合体系的平均活化能为101．1kJ·mol^-1，反应级数为0．98，凝胶和固化温度分别为205．1℃、239．3℃，确定固化工艺为210℃／2h＋230℃／2h。在该固化条件下固化后材料脆断断面扫描电子显微镜（SEM）表明制备得到CSR呈纳米级均匀分散的复合材料。

英文摘要：

Dynamic curing behaviors of benzoxazine/core-shell rubber composites were studied by non-isothermal differential scanning calorimetry （DSC）. The curing reaction kinetics and kinetics parameters were obtained utilizing Kissinger, Ozawa, and Crane methods. The result showed that the average activation energy was 101. 1 kJ · mol^- 1, reaction order was 0. 98, gel and curing temperature was 205. 1 ℃ and 239. 3 ℃, respectively. The curing technology was 210 ℃ /2 h＋230 ℃/2 h. The scanning electron microscope （SEM） confirmed the well dispersion of nano CSR in cured composite matrix with the curing technology.
