Abstract:

Bisphenol-A epoxy resin E-51 was cured by [C6mim]FeCl4 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]FeCl4/mixed amine have better mechanical properties, thermal properties, and aging properties. The effect of the amount of [C6mim]FeCl4 on the properties of the cured epoxy resin systems was also investigated. Tensile strength of the [C6mim]FeCl4/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]FeCl4/mixed amine cured epoxy resin system is 28 MPa. Therefore, the [C6mim]FeCl4/mixed amine cured epoxy resin system is a new type of epoxy resin cured system which can be applied under high temperature.
