Abstract The self-made carboxyl-terminated liquid fluororubber was used as raw material, aziridine as curing agent and acetone as solvent to cure it by a one-pot method. The structure, curing process and heat resistance of the cured product were studied by infrared spectroscopy (IR), diffe-rential scanning calorimetry (DSC) and thermogravimetric meter (TGA). At the same time, the effects of curing agent dosage and curing time on the solvent resistance and mechanical properties of the cured product were investigated. The results show that the curing temperature of aziridine and terminal carboxyl liquid fluororubber is between 90 ℃ and 100 ℃. As the amount of the curing agent added increases, the thermal stability of the product gradually increases, and the solvent resistance is excellent. When the curing agent is used in an amount of 14% and the curing time is 4 h, the overall performance of the cured product is optimal.

Key words： carboxyl-terminated liquid fluororubber aziridine curing agent curing thermal performance mechanical property
