چکیده
|
In the epoxy prepreg manufacturing industry, dicyandiamide (dicy) is a well-known latent curing agent with a curing temperature of 200 °c which necessarily uses accelerators like diuron to reduce the curing reaction temperature# the aim of this study was to investigate the curing mechanisms of the epoxy-dicy and epoxy-diuron curing systems in order to obtain the optimum composition of this formulation# using ir and dsc techniques to investigate the curing mechanisms and to obtain the optimum amount of dicy were used to complete the curing reaction# result of experiments showed that diurane performed part of the curing reaction in addition to acceleration# it was observed that the epoxy-dicy curing reaction does not follow the stoichiometric ratio#
