Abstract:
采用非等温DSC法对聚乙烯基对苯二甲酸二(对丁氧基苯酚)酯(PBPCS)/环氧树脂/甲基四氢苯酐固化体系的固化反应热行为以及固化动力学进行了研究,分别利用Kissinger和Ozawa动力学模型计算得到各体系固化反应的表观活化能,利用Crane模型计算出固化反应级数,得出了适于该树脂体系固化反应过程的动力学方程.结果表明该体系固化反应按照一级反应进行,PBPCS的加入不改变环氧树脂的固化机理,甲壳型液晶高分子PBPCS可以用于环氧树脂的改性研究.通过固化体系的DSC分析确定了体系固化工艺为90℃/2h→120℃/2h→140℃/1.5h,为聚乙烯基对苯二甲酸二(对丁氧基苯酚)酯/环氧树脂/甲基四氢苯酐体系的固化、性能测试和应用提供了理论依据,也为甲壳型液晶高分子改性环氧树脂的研究提供一定理论基础.
