稀土金属氧化物与聚磷酸铵阻燃剂协同作用的研究

Study on Synergistic Effect of Rare Earth Metal Oxide and Poly-triammonium Phosphate Fire Retardant

从聚合物材料的燃料特点出发 ,分析和讨论了聚合物材料的阻燃特性。实验采用添加无机阻燃剂聚磷酸铵及稀土金属氧化物 ,提高了硬质聚氨酯泡沫塑料的阻燃性能 ,并研究了添加型无机阻燃剂与硬质聚氨酯泡沫塑料氧指数的关系 ,得出了一些规律性结果 ,这些结果对进一步研究耐燃的硬质聚氨酯泡沫塑料配方有一定的指导意义。

According to burning performance of polyer materials, fire retardant charateristics of polyer materials were analyzed and discussed in this paper. fire resistance of polyurethane foaming plastic was improved through adding fire retardant of rare carth metal oxide and poly-triammonium phosphate. Oxygen index of additive inorganic fire retardant and polyarethane foaming plastic was studied.
