| Abstract: | Modified dicyandiamide was synthesized by reaction of dicyandiamide with m-toluidine under different conditions.The structure of product was analyzed through melting point and IR spectrum.Dicyandiamide derivative was used as latent curing agent of epoxy resin.The experiment results showed that modified dicyandiamide had excellent reactivity,and dicyandiamide modified by m-toluidine /epoxy resin E-44 system could be stored stably in room temperature for a long time. |
