One chemical approach using nitric acid as the solvent to decompose thermosetting epoxy resin was discussed The samples were prepared by using different kinds of curing agents,namely polyamide (PA651),isophorone diamine ( IPDA ),4,4-diaminodiphenylmethane (DDM) and 2-ethyl-4-methy-imidazole ( EMI-2,4) and different kinds of epoxy resins,namely bisphenol-A epoxy resin(E-44),bisphenol-A epoxy resin(E-51 ),N,N,N,Nteraglycidy 4,4diaminodiphenyl methane (AG-80) and diglycidyl-4、5-epoxycyclohexane-1,2-dicarboxylate (TDE-g5).Their effects on decomposition rate were investigated and the decomposition products were analyzed by Infra-red (IR) spectra,and Gas Chromatography-Mass Spectrometry (GC-MS).Based on conclusions drawn from experiments,the mechanism of degrading thermosetting epoxy resin with nitric acid was envisaged tentatively.
