| 摘 要： | 随着高分子材料的不断开发,涌现出一大批用于阻燃和热辐射防护的耐高温纤维,如Basofil、Kermel、visil、Nomex、P84、PBI和PBO等纤维,除了在衣着领域的应用外,在消防服、工业用阻燃防护服以及汽车等的内装饰物和家用防火材料等方面,具有更优异的防护功能和穿着舒适性。在实践中,人们发现有的阻燃纤维织物,虽然有阻燃效果,但在燃烧时烟雾很大,在火灾中有相当一部分人不是被烧死而是窒息死亡;有的阻燃织物燃烧时烟雾密度很低,但含有极毒化合物如HCN,因此研究阻燃纤维的烟雾成分从而研究其毒性具有重要的意义。

| Abstract: | The high temperature decomposition of antiflaming fibre was studied by pyrolysis gas chromatographymass spectrometry. The results showed that main unit structure of two kinds of antiflaming fibre were Respectively poly phenylene sulphide and acrylonitrile-vinyl chloride copolymer.The identification of substance of hightemperature decomposition provides the basis of the investication of toxicity of antiflaming fibre. |
