Microstructure and affecting factors of epoxy resin cured by electron beam radiation

  • 摘要: 采用扫描电镜对不同固化时间下电子束固化环氧树脂的微观结构进行观察和分析,探讨其形成过程,并研究了树脂分子结构、相对分子质量、树脂体系组分及辐射条件对微观结构的影响. 实验结果表明,环氧树脂经电子束固化后形成片层结构,树脂分子结构和分子量对其固化微结构的影响不大;不同结构、分子量的环氧树脂电子束固化过程中均会经历预聚体结构—圆片网络—圆片形成—圆片增长的生长过程,故其微观结构都呈现圆片状形貌;随着辐射剂量的增加,圆片逐渐增大;存在最佳引发剂用量,使圆片尺寸达到最小.
