| 摘 要： | 在自修复聚合物复合材料中,修复剂黏度和高聚物强度是保证自修复过程实现的重要因素。文中以合成用于自修复材料的环氧树脂微胶囊为目的,在双酚A型环氧树脂(E-51)中加入稀释剂正丁基缩水甘油醚(BGE)降低黏度,采用傅里叶红外(FT-IR)分析稀释剂对环氧胶粘剂与微胶囊咪唑类固化剂交联反应的影响,表征了在固化过程中稀释剂参与环氧胶粘剂与咪唑类固化剂的交联反应;使用差示扫描量热(DSC)技术对该固化反应进行动力学研究,确定出稀释剂的最佳用量;通过拉伸实验测定了环氧树脂固化产物的强度,表明BGE的加入增强了环氧树脂的胶粘性能。

| Abstract: | This paper is concentrated on molecular design of adhesive materials,cross-linking structure and property control in the synthesis of epoxy resin microcapsules and in the application of self-healing material.1-butyl glycidyl ether was carefully selected and added into epoxy adhesive to decrease viscosity and to increasing liquidity.The crossing structure generated by epoxy and microcapsulated imidazole curing agent in the usage of the diluents was investigated using Fourier-transform infrared spectroscopy(F... |
