| 摘 要： | 研究了EG协同三嗪系大分子膨胀型阻燃剂阻燃HDPE,通过极限氧指数(LOI)、热重分析(TGA)、扫描电镜(SEM)等测试手段进行了分析。结果表明当EG与APP/CFA/SiO2共同使用阻燃HDPE的氧指数比单独加入两种阻燃剂的氧指数都有所提高,SEM测试表明EG与APP/CFA/SiO2共同使用燃烧后表面形成一层致密的保护层,阻止了聚合物的进一步燃烧。

| Abstract: | The flame retarding of HDPE by synergetic flame retardance between EG and triazine macromolecular expansion flame retardant was studied. By means of the limiting oxygen index （LOI）, thermal gravimetric analysis （TGA） and scanning electron microscope （SEM） tests, etc, the analysis was carried out. The research results showed that the LOI of flame-retardant HDPE with EG and APP/CFA/SiO2 was better than the LOI that the two kinds of flame retardants used alone. The SEM test indicated that there was a compact protective layer formed on the surface after combustion when EG and APP/CFA/SiO2 were used synergistically, which prevented further combustion of the polymer. |
