Synthesis of a Novel Halogen-Free Intumescent Flame Retardant Agent
Abstract:
A novel non-halogen intumescent flame retardant agent (IFR) was prepared by using phosphoric acid, pentaerythritol and aniline as raw materials. The structure and thermal stability of IFR were investigated by means of Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). The flame retardant properties of IFR were investigated based on its inflation and char yield performance at 500°C. The results show that both the reaction time and mole ratio of raw materials have effects on the inflation and char yield of IFR.
