CHEN LIANXI, ZHANG HUILING, LIU QUANWEN, et al. Characteristic of Curing Reaction of Epoxy Resin with Dicyanodiamide Modified by Aromatic Amines. [J]. 2006, (4): 426-430.DOI:
The modified dicyanodiamide derivatives that were synthesized by reactions of dicyanodiamide with aniline
p-toluidine
m-toluidine
were used as latent curing agent of epoxy resin.By differential scanning calorimetry(DSC) and infrared spectrum(FT-IR)
curing reactions of epoxy resin systems containing modified dicyanodiamide derivatives were studied.The results show that the modified eicyanodiamide derivatives had excellent reactivity
and epoxy resin E-44 was cured in moderate temperature(110-120 ℃).Modified Dicyanodiamide modified by aromatic amine/epoxy resin E-44 systems possessed a long storage life. Reaction mechanism of modified dicyanodiamide derivatives with epoxy resin was also discussed.
