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.

聚磷酸铵和植酸钡协同改性聚氨酯泡沫的阻燃性能和热稳定性研究

以植酸和碳酸钡为原料制备了植酸钡（Pa-Ba），然后用Pa-Ba和聚磷酸铵（APP）协同作用制备了阻燃改性聚氨酯泡沫（PUF）。通过热重分析、圆锥量热仪（CONE）和烟密度（Ds）研究了改性聚氨酯泡沫的阻燃性能和热稳定性。结果表明，添加了 5 % Pa-Ba 和 10 % APP 的改性聚氨酯泡沫（PUF-A10-PB5）的积分程序分解温度和活化能最高，表明其热稳定性优于其他样品。此外，PUF-A10-PB5 在不同辐射强度下的总放热量最低，在有焰和无焰条件下的 Ds 最小，透光率最高。研究结果表明，PUF-A10-PB5 具有更好的阻燃性能和热稳定性，可为今后植酸改性 PUF 的阻燃性能实验研究提供有益的参考。
