摘　　要：采用1-己基-3-甲基咪唑四氯化铁盐([C6mim]FeCl_4)与混合胺复配室温(20℃)固化双酚A型环氧树脂E-51,并与其它脂肪胺类室温固化E-51体系在力学性能、热性能、耐老化性能方面的数据进行了比较,同时分析了[C6mim]FeCl_4不同添加量对固化体系性能的影响,结果显示:[C6mim]FeCl_4/混合胺复配室温固化E-51体系的室温拉伸强度可达90 MPa,高温(120℃)下也保持了良好的力学性能,热失重(5%)分解温度为310℃,200℃老化7 d后,拉伸强度为28 MPa,是一种可在高温下使用的新型环氧树脂室温固化体系。Bisphenol-A epoxy resin E-51 was cured by [C6mim]Fe Cl4 and mixed amines at room temperature（ 20 ℃）. Compared to other E-51 systems which were cured by aliphatic amine,E-51 systems cured by[C6mim]Fe Cl4/ mixed amine have better mechanical properties,thermal properties,and aging properties.The effect of the amount of [C6mim]Fe Cl4 on the properties of the cured epoxy resin systems was also investigated. Tensile strength of the [C6mim]Fe Cl4/ mixed amine cured E-51 system reaches 90 MPa,and the system maintains its excellent mechanical properties at high temperature（ 120 ℃）. The TGA result shows that the decomposition temperature is 310 ℃ when the mass loss of epoxy system reaches 5%. Even after 7 days aging at 200 ℃,the tensile strength of the [C6mim]Fe Cl4/ mixed amine cured epoxy resin system is 28 MPa.Therefore,the [C6mim]Fe Cl4/ mixed amine cured epoxy resin system is a new type of epoxy resin cured system which can be applied under high temperature.
