一种碳纳米管环氧树脂固化剂的制备方法
摘要：
本发明公开了一种碳纳米管环氧树脂固化剂的制备方法，包括如下步骤：羧基化碳纳米管的制备：将碳纳米管加入硫酸/硝酸在室温下超声10～120min，在50～170℃温度下反应，得到羧基化碳纳米管；羧基化的碳纳米管溶于N，N’－二甲基甲酰胺溶液中，室温下超声10～120min，在温度为60～200℃，反应时间为12～120h，加入芳香族胺基化合物及N，N’－二环己基碳酰亚胺缩水剂，制备芳香族胺基化碳纳米管。本发明的有益效果是：在碳纳米管表面接上芳香族胺基化合物环氧树脂固化剂，既可以提高环氧树脂的力学性能又可以提高环氧树脂的热稳定性，并提高碳纳米管在环氧树脂中的分散性和含量，改善碳纳米管与环氧树脂的界面。
摘要（英）：

The preparation process of carbon nanotube epoxy resin curing agent includes the following steps: reaction of carbon nanotube and sulfuric acid/ nitric acid at 50-170 deg.c under the ultrasonic action for 10-120 min to obtain carboxylated carbon nanotube; dissolving the carboxylated carbon nanotube in N, N'-dimethyl formamide solution to reaction at 60-200 deg.c under the ultrasonic action for 10-120 min, and adding aromatic amino compound and N, N'-dicyclohexyl carbimide shinking agent to prepare the aromatic carboxylated carbon nanotube. The epoxy resin curing agent with aromatic amino compound grafted to the surface of carbon nanotube can raise the mechanical performance of epoxy resin, raise the heat stability of epoxy resin, raise the dispersivity and content of carbon nanotube inside epoxy resin and improve the interface between carbon nanotube and epoxy resin.
