Abstract
以CaO,Fe(NO3)3·9H2O和Ce(NO3)3·6H2O为原料,采用机械化学法制备了钙铁层状金属氢氧化物和钙铁铈层状金属氢氧化物.以XRD和热重分析表征了产物的结晶结构及热分解行为,结合ICP光谱测定,推测产物的化学组成分别为Ca0.51Fe0.49(OH)2(NO3)0.49·0.69H2O和Ca0.51Fe0.37Ce0.12(OH)2(NO3)0.49·0.59H2O.将上述产物作为功能填料加入室温硫化硅橡胶,其添加量为0.7g/g时,复合材料的拉伸强度达到4.5MPa,氧指数约为34.5%,具有良好的阻燃性能和力学性能,优于常规的Mg(OH)2和镁铝层状金属氢氧化物.含有0.2g/g钙铁铈层状金属氢氧化物的室温硫化硅橡胶复合材料最大烟密度为8.46,抑烟性能优异
