| 摘 要： | 主要研究了多胺－硫脲缩聚物对环氧－聚酰胺固化体系的促进作用。通过示差扫描量热，对改性前后固化反应动力学多种参数进行了计算，说明了这种增强作用是由于多胺－硫脲缩聚物的加入使体系动力学反应的前置因子和反应速率常数大幅度提高。在此基础上研制的环氧树脂／聚酰胺／缩聚物胶粘剂具有高强度，高耐湿热性，室温下可快速固化的特点。

| Abstract: | The curing reactivity of the system based on epoxy cured with polyamide could be significantly accelerated by the polymer of polyamine and thiourea condensation. Thermal analysis explained that the acceleration was associated with a substantial increase in frequency factor and react constant caused by the incorporation of the PAT condensation. The adhesive based on Epoxyide/PA/PAT contains the features of high strength, high damp-heat resistance and room-temperature quick-curing. |
