Abstract: Ammonium polyphosphate (APP) with reticulated structure was prepared by heating a mixture of 85% food grade phosphoric acid and melamine under wet ammonia atmosphere. Its water-solubility, XRD, 13C NMR, FTIR and TG were investigated, and compared with those of APP-I and APP-II. Results show that this product has excellent water-resistence, its XRD spectrum is similar to that of APP-V in literature, its 13C NMR and FTIR spectra show that this product is a cross-linked and reticulated structure of ammonium polyphosphate chains with triazine ring as basebone. TG tests show that the residual weight at 700℃ for this product is 53.6% , higher than 40.29% for APP-I and 36.18% for APP-II, meaning its excellent thermal stability at high temperature.
Key words: Ammonium polyphosphate, crystal form V, Water resistance, Thermal stability.
