In this study, a novel phosphorus-nitrogen containing intumescent flame retardant (P-N IFR) poly(melamine 2-carboxyethyl(phenyl) phosphate)(PMCEP) was prepared via the reaction of 2-carboxyethyl (phenyl) phosphinic acid (CEPPA) and melamine (MEL) in two-steps. Meanwhile, the molecular structure of the chemical compound was determined by FTIR,1H-NMR and elemental analysis; and the thermal properties was investigated by means of TGA. Combustion studies revealed high limiting oxygen index (LOI) indicative of better flame-retardancy properties for PBT resin.

In this study, N,N-(2,4-diamino-1,3,5-triazinyl) diethylenetriamine were synthesized by cyanuric chloride, diethylenetriamine and ammonia with a novel process in three steps, and it can be used as charring agent in intumescent flame retardant. Its chemical structures were characterized by Fourier-transform infrared spectroscopy (FT-IR) and elemental analysis. Meanwhile, the TGA results showed that triazine-based charring agent had good thermostability. Furthermore, the fire performancce of composites blended by the flame retardant and polypropylene was investigated by vertical burning test. The results revealed good fire retardancy that flame retardant polypropylene with 5.1wt% charring agent, 2.8wt% anti-dripping and 20.1wt% APP, was reached UL-94 V-0 rating.
