摘要： 比较了苯并噁嗪单体(BZ)和插层于蒙脱土层间的苯并噁嗪单体(BZ/MMT)两种体系的动态固化特性.实验发现,经有机化处理的蒙脱土在BZ/MMT体系的固化行为中起着重要的作用,使该体系存在催化聚合和热聚合两类固化单元反应.结果造成两种体系在特征固化温度、固化速率、反应热、反应级数以及表观活化能上存在明显的差别.

关键词: 苯并噁嗪, 蒙脱土, 动态固化行为

Abstract: The dynamic curing behavior of two curing systems which include pristine polybenzoxazine monomer(BZ) system and polybenzoxazine monomer insertion montmorillonite(BZ/MMT) system was compared. It was found that the organically treated played a vital role in curing behavior of BZ/MMT system and two types of curing reactions occurred in BZ/MMT system which includes: catalyzed polymerization and thermal polymerization, as a result, big difference in the two systems occurred at the characteristic curing temperature, curing rate, the heat of reaction, reaction order, as well as apparent activation energy.

Key words: Polybenzoxazine, Montmorillonite, Dynamic curing behavior
