【摘要】 研究了以Al(OH) 3 、Mg(OH) 2 、煅烧高岭土、白炭黑为主要组分的超细活性无机复合阻燃填料应用于PVC电缆料的阻燃性能、力学性能和电绝缘性能并与其他无机阻燃填料进行了比较。结果表明 :超细活性无机复合阻燃填料应用于软PVC ,其力学性能和电性能可达到GB/T 8815— 2 0 0 2标准 ,氧指数达 3 5 6% ,烟密度为 174 7。这种超细活性无机复合阻燃填料具有高效阻燃、填充增强和电绝缘性三种功能。更多还原

【Abstract】 An ultrafine active inorganic composite flame-retardant filler based on aluminum hydroxide and magnesium hydroxide was employed in poly(vinyl chloride) cable compounds. Results show that flexible PVC products filled with the flame-retardant filler possessed superior properties of flame retardance (oxygen index 35.6) and smoke restraint (smoke density 174.7), with mechanical and electrical properties coming up to national standards (GB/T 8815—2002).更多还原
