Synthesis and Characterization of Triazine-Based Charring Agent and its Application in Flame Retarded Polypropylene

Article Preview

Abstract:

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.
