摘要
双氰胺作为最早的潜伏性固化剂之一,其固化后的环氧树脂具有优异的机械性能,但仍然有固化温度过高等缺陷。针对这一缺陷,本文从降低双氰胺上氰基的吸电子能力进而增强固化活性以及引入相似基团增强双氰胺和环氧树脂的相容性两方面对国内外文献进行归纳总结,并对改性双氰胺固化后的环氧树脂的应用进行了展望。
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.
