Analyses on Electron Beam-Curing Reaction of Epoxy Resin

Abstract

Abstract: The curing process of bisphenol epoxy resin irradiated witHElectron beam (EB) was studied.The effect of different initiators and diluents on radiation reaction was analyzed.IR, ESR, GC-MS were used to study radiation reaction mechanism of epoxy resin by using epoxy propane as a model compound.The cation ring-opening polymerization process including decomposition of diaryliodonium salts under EBradiation and production of protonic acid that initiate polyreaction can be deduced.By analyzing an irradiated area of epoxy resin, it can be seen that intensive scattering of EBoccurs in the resin system.The EB curing reactions spread inwards layer upon layer around active center when epoxy resin system is irradiated and whole cured area consists of many lamellar structures.

Key words: Epoxy resin, Radiation curing, Electron beam, Reaction process, Microstructure
