摘要
国产氢氧化铝经超细加工，表面改性和阻燃增效作用，合成的阻燃剂平均粒径可达到１～２μｍ，对ＥＰＤＭ的阻燃性能评价表明氧指数可达到３４～４４％，垂直燃烧达到美国ＵＬ－９４Ｖ－０级标准。
Domestic aluminium hydroxide can be processed by superfining,surface modifying and synergism,the average particle size of synthetic flame retarder will reach about 12 m.The evaluation test of flame retarding properties in EPDM showed that oxidation index can reach 34%44%,and vertical combustion can meet the requirement of V0 grade,which is USA UL-94 standard.
