摘要
用合成的胺化聚碳酸酯(a-PC)改性环氧树脂(EP)以形成新的交联网络体系。以叔胺为固化剂,采用DSC、AFM等测试技术对本体系的玻璃化转变温度、表面形貌和力学性能进行了测试。结果显示,改性体系只有1个玻璃化转变温度,且随着a-PC的加入,改性体系的Tg从104.0℃降低到83.8℃。改性体系的力学性能得到改善,冲击韧性比纯EP提高了11%。
An amino-polycarbonate was synthesized, and the morphology features and properties of epoxy resin/amino-polycarbonate system cured by a tertiary amine were studied. The glass transition temperature, surface morphology, and mechanical properties of EP/amino-PC/BDMA were investigated by DSC, AFM and etc. The epoxy resin/amino-polycarbonate blend exhibited a single glass transition temperature. With the addition of the amino-polycarbonate, the glass transition temperature of the modified system decreased from 104. 0℃ to 83.8℃. The mechanical properties of the modified epoxy resin system were improved and the impact toughness of the modified system increased by 11%.
