Abstract
Barium phytate (Pa–Ba) was prepared by phytic acid and barium carbonate, and then the flame-retardant modified polyurethane foam (PUF) was synergized with Pa–Ba and ammonium polyphosphate (APP). The flame retardant properties and thermal stability of the modified PUFs were investigated by thermogravimetric analysis, cone calorimetry (CONE) and smoke density (Ds). The results showed the modified PUF with the addition of 5 % Pa–Ba and 10 % APP (PUF-A10-PB5) had the highest integral programmed decomposition temperature and the activation energy, indicating that its thermal stability was better compared with other samples. In addition, PUF-A10-PB5 had the lowest total heat release under different radiation intensities, and it had the smallest Ds and the highest light transmittance under the flame and flameless condition. The current results indicated that PUF-A10-PB5 had better flame-retardant properties and thermal stability, which can provide a useful reference for future experimental studies on the flame retardant properties of phytate-modified PUF.
