| 摘 要： | 通过非等温和等温差式扫描量热法(DSC)对硫磺(S)固化2,2’-二烯丙基双酚A型环氧树脂(DADGEBA)的动力学进行了研究。从DSC曲线两个放热峰得知,DADGEBA/S体系是两步反应,通过等温DSC分析确定该体系在温度高于170℃低于210℃时满足Kamal自催化模型,通过非等温DSC确定该体系在温度高于210℃时,满足n级反应模型,得到了动力学模型的相关参数。DADGEAB/S体系在整个固化反应过程中满足两种动力学机理函数,这与DADGEBA/S体系双固化机理相符。

| Abstract: | The curing kinetics of diglycidyl ether of 2,2’-diallyl bisphenol A （DADGEBA） cured with sulfur （S） was investigated by non-isothermal and isothermal differential scanning calorimetry （DSC）. The double exothermic peaks in DSC curve showed that the curing process of DADGEBA/S system was a two-step reaction. The isothermal DSC analysis confirmed that the curing reaction followed Kamal ’s autocatalytic model when the reaction temperature was between 170℃ and 210℃, and when the temperature was higher than 210℃, the nth-order reaction model could be used to describe the curing reaction process of the DADGEBA/S system. The two kinetic equations in the entire reaction process of DADGEBA/S system were consistent with the two-step reaction mechanisms of the same system. |
