AbstractIn the present study, a novel polysilicone PMDA was synthesized and the effect of PMDA on the flame retardancy of epoxy resin (EP) was investigated by cone calorimeter measurement. EP/PMDA (FREP) composite exhibited lower peak heat release rate (PHRR) and total heat release (THR) in comparison with those of pure EP, indicating the higher fire safety of FREP. Furthermore, the thermal degradation behavior of FREP composite was investigated by the TGA measurement under non-isothermal conditions. The Kissinger and Flynn-Wall-Ozawa methods were both used to analyze the thermal degradation process of EP composites. The results illustrated that PMDA remarkable enhanced the activation energies of EP thermal degradation in the final stage, revealing that the flame retardant PMDA stabilized the residual char layer and improved the flame retardancy of EP in the final period of thermal degradation process.
