三（2，4，6－三溴苯氧基）锑酸酯的合成及其阻燃性能与阻燃机理

SYNTHESIS AND CHARACTERIZATION OF TRIS (2,4,6 TRIBROMOPHENOXY) ANTIMONIC ACID ESTER AND ITS FLAME RETARDATION MECHANISM

合成了三（２，４，６－三溴苯氧基）锑酸酯，通过元素分析和ＩＲ光谱予以表征，并就其对聚乙烯和聚丙烯的阻燃性能与阻燃机理进行了研究。结果表明：这种分子中同时含有溴、锑的阻燃剂，比相应的仅含溴和仅含锑的阻燃剂混合物具有更高的阻燃性能。

Tris (2,4,6 tribromophenoxy) antimonic acid ester was synthesized and was characterized by elementary analysis and IR spectroscopy.Its effect and mechanism of flame retardation in polyethlene and polypropylene was studied.The results show that it has much higher flame retardation effect than the mixed flame retardant of tribromophenol and antimonic oxide.
