Abstract

Epoxy resin is the most common thermosetting polymer, forms a three-dimensional cross-linked network structure under curing reaction by with a curing agent or catalyst. Epoxy resin has been used in various industrial applications because of its good adhesion, chemical resistance, thermal resistance, heat resistance and mechanical properties. However, due to the high flammability, various applications are limited, so flame retardant must be added to the epoxy resin to improve flame retardancy. In this study, the thermal, physical properties and flame retardance of cured resins were studied by using a new co-curing agent which gives flame retardancy to epoxy resins. The trifunctional imidazole co-curing agent was synthesized by introducing an imidazole compound having fast curing properties into the triazine structure, and then analyzed by NMR. The epoxy cured product was prepared by using the synthesized co-curing agent and the amine curing agent, and the rapid curing property of the epoxy according to the addition of the co-curing agent was confirmed by using DSC. Physical properties of the epoxy cured product using the co-curing agent were evaluated by UTM, and thermal properties and flame retardance were confirmed by TGA and micro calorimeter.
