N2 - In this research, a novel triazine-based polymeric flame retardant (TBMC) was synthesized. The intumescent flame retardant (IFR) system was formed by combining. TBMC with ammonium polyphosphate (APP), and is applied to retard the combustion of polypropylene (PP). PP/IFR samples (APP/TBMC = 3/1 to 1/1) achieved increased limited oxygen index (LOI) values and passed the vertical burning (UL-94) V-0 rating. Herein, cone calorimeter tests show that the heat release rate (HRR) and fire growth index (FGI) of PP/APP/TBMC blends were obviously decreased compared to those of pure PP and PP with 25 wt% APP. The thermogravimetric analytical (TGA) results showed that the TBMC/APP system could improve the thermal and thermal-oxidative stability of the char residues. The char residues were further investigated by visual observation and scanning electron microscopy (SEM). The compact char residues formed hindered the transfer of gas and heat during combustion, ultimately endowed PP/IFR systems improved flame retardancy.
