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.

The flame-retardant of Lanthanum phenylphosphinate(LaPi) was prepared and its combination with intumescent flame retardant (IFR) in polypropylene (PP) was analysed using thermogravimetric analysis (TGA), limiting oxygen index (LOI) and the UL-94 test. Compared with using IFR alone, using the combination of LaPi and IFR gained the better classification in the UL 94 test thanks to the combination of the different mechanisms. When 20 wt% loading of flame retardant of LaPi and IFR, a halogen-free V-0 PP material was achieved with a LOI of 31%.
