| 摘 要： | 设计了含改性松香无苯环的环氧固化体系和无松香的对照体系,分别是无松香体系Ⅰ：丁二醇二缩水甘油醚（BDGE）和甲基六氢苯酐（MeHHPA）;无规体系Ⅱ：丙烯酸松香（AR）、BDGE和MeHHPA;有规体系Ⅲ：丙烯酸松香基环氧树脂（ARE,由AR和BDGE预聚而来）和MeHHPA。对三体系的固化反应应用动态示差扫描量热仪（DSC）进行了研究,利用KAS法求得不同转化率下的表观活化能,通过整个反应过程反应活化能的变化,得到了三体系反应的内在机理,结果发现松香基的引入及引入顺序都对固化反应产生影响。

| Abstract: | SystemⅠwas obtained by reacting 1,4-butanediol diglycidyl ether (BDGE) with methyl hexahydro-phthalic anhydride (MeHHPA) as curing agent; System Ⅱ was obtained by reacting BDGE with acrylic acid rosin (AR) and MeHHPA as curing agent; system Ⅲ was obtained by reacting ARE synthesized by AR and BDGE with MeHHPA as curing agent. Curing reactions of the three systems were analyzed by differential scanning calorimeter (DSC) measurements. KAS method was used to calculate the values of the activation energy at different conversion. The reaction mechanisms of the three systems were compared,it was found that the introduction of rosin-based made the apparent activation energy higher and the different orders of the introduction made the apparent activation energy different. |
