差示扫描量热法研究改性双马来酰亚胺的固化过程

STUDY ON THE CURING REACTION OF MODIFIED BMI CDR9418 WITH DSC

摘要: 用差示扫描量热法(DSC) 研究了CDR-9418 双马来酰亚胺树脂的固化过程, 用动态和静态两种方法分析了其固化反应过程, 发现有两个固化反应放热峰, 并用T-Φ 外推法确定了凝胶温度、固化温度和后固化温度等固化工艺参数。

Abstract: The curing reaction of modified BMI CDR9418 was studied with DSC. The curing reaction was carried out by constant heating and isothermal methods. And two curing exothermic peaks were found. Gelling temperature, curing temperature and treating temperature were calculated by extrapolating T.
