Research progress on modified dicyandiamide cured epoxy resin
As one of the earliest latent curing agents,dicyandiamide has excellent mechanical properties in cured epoxy resin,but still has defects such as high curing temperature.In response to this deficiency,domestic and foreign literature from two aspects:reducing the electron withdrawing ability of the cyanide group on dicyandiamide to enhance curing activity,and introducing similar functional groups to enhance the compatibility between dicyandiamide and epoxy resin,was summarized in this article.The application prospects of modified dicyandiamide cured epoxy resin were also discussed.
