一种新型卤代磷酸酯阻燃剂的合成及应用

目的 研究一种新型卤代磷酸酯的合成工艺，性能及阻燃效能。方法 将合成的磷酸酯用于阻燃软质聚氨酯泡沫塑料（ＦＰＵＦ），测定该软泡阻燃性能及物理－机械性能，并以此评价该磷酸酯的阻燃作用。结果与结论 伸长率及回弹率降低约１０％，而拉伸强度基本不变。

Synthesis and Applications of a Novel Halogenated Phosphate Flame Retardant

Aim To study the synthetic procedure, properties and flame retardant efficiency of a novel halogenated phosphate. Methods The obtained phosphate was used to treat flexible polyurethane foam(FPUF), and the flame retardant and physicomechanical performances of FPUF were measured to evaluate the phosphate's efficiency. Results and Conclusion When the loading of the flame retardant is 12%-15% of polyether, the LOI of FPUF is increased to 23 5%-25 5% from 17 5%, and the horizontal burning rate is decreased by 68%. But the elongation and the rebound degree of FPUF are cut down by about 10%. While the tensile strength remains unchanged basically.
