| Abstract: | The curing temperature for epoxy resin system which is cured by dicyandiamide alone is usually high. An imidazole-salt was synthesized by using NiCl_2 and imidazole, and used to accelerate the curing reaction for dicyandiamide and epoxy resin. The results showed that the curing temperature of this system was decreased to the moderate temperature from 90 to 120 ℃, and the storage time, moisture resistance and heat resistance of the epoxy resin were also improved. |
