纳米三聚氰胺磷酸盐的合成及其在酚醛泡沫中的应用*
Keywords: 有机高分子材料,材料合成,纳米三聚氰胺磷酸盐,溶剂热方法,酚醛树脂
Abstract:
？以三聚氰胺和磷酸为原料，采用溶剂热方法合成出纳米三聚氰胺磷酸盐(nmp)阻燃剂。用傅里叶变换红外光谱(ftir)、x射线衍射(xrd)、扫描电镜(sem)等手段表征产物的组成和结构，研究了不同溶剂(蒸馏水、无水乙醇和苯)、不同类型的表面活性剂(十二烷基硫酸钠(sds)、十六烷基三甲基溴化铵(ctab)、壬基酚聚氧乙烯醚(np))、以及反应温度和反应时间对产物形貌的影响。结果表明:只有使用苯为溶剂才能合成出nmp，表面活性剂的种类对产物的形貌有较大的影响。将合成的nmp与市售的微米级mp(mmp)在增韧酚醛泡沫中的阻燃性能和力学性能对比，nmp阻燃增韧酚醛泡沫的弯曲强度比mmp阻燃增韧酚醛泡沫提高了39%。
