| 摘 要： | 采用差示扫描量热法(DSC)在等温和动态条件下对3234中温固化环氧树脂体系的固化反应动力学进行了研究,建立了固化反应动力学方程;并模拟实际固化温度历程,采用测定不同固化阶段样品残余反应热的方法对固化反应动力学方程进行了验证。结果表明,3234中温固化环氧树脂体系的固化反应动力学符合自催化反应动力学模型,动态实验得到的固化反应动力学方程与验证结果符合得较好。

| Abstract: | The cure kinetics of middle temperature curing 3234 epoxy resin system was studied under isothermal and dynamic curing conditions by Differential Scanning Calorimetry (DSC) technique. The cure kinetic equations were established. By simulating practical temperature procedure of curing, the cure kinetic equations were verified by means of determining the residual heat of reaction of samples with different cure degrees. The results showed that the cure kinetics can be described by the autocatalytic kinetic model . The cure kinetic equation obtained from dynamic test agreed well with the experimental results. |
