摘要
本文研究了三(2,4,6-三滇苯氧基)锑的合成方法及其阻燃性能.用苯酚、溴和三氯化锑在一定条件下可合成该化合物,产率达86%以上;该化合物在340℃以下是稳定的,对聚乙烯和聚丙烯都具有良好的阻燃效果,当其在聚乙烯和聚丙烯中的添加量分别为5%和8%时,氧指数就提高到了26.8和28.3,且对阻燃产品的其它性能无不良影响.
In this paper, a method of synthesizing tris-(2,4, 6-tribromophenolato) antimony(Ⅲ) was reported,and the flame retarding character of this compound was also approached. The compound was propared by the reaction of tribromophenol with antimonous chloride in proper conditions,the yield reached 86. 5%. In polyethylene (PE) and polypropylene(PP),the compound has a high efficiency of flame retarding.
