摘　　要：在酚醛泡沫发泡过程中,添加蒙脱土,对酚醛泡沫进行改性,并复配聚磷酸铵阻燃剂得到的同时增强力学性能和阻燃性能的酚醛泡沫。扫描电子显微镜分析(SEM)结果显示,复合材料中的蒙脱土已完全剥离,添加适量的蒙托土能改善酚醛泡沫的泡孔结构,使泡孔尺寸显著减小,泡孔密度明显增大。力学性能测试结果表明,剥离型的蒙脱土能明显提高酚醛泡沫的拉伸强度和压缩强度。蒙脱土复配适量的聚磷酸铵具有力学和阻燃协同效应。During the foaming process of phenolic foam, adding montmorillonite/ammonium polyphosphate can improve the mechanical and inflaming retarding properties of phenolic foam. The SEM results showed that the MMT were exfoliated in the composite. The morphology of the porous structure was more uniform, smaller cellular size and largerer cell density. The exfoliated MMT could enhanced the tensile and compression strengthes of phenolic foam. MMT and ammonium polyphosphate showed synergistic effect.
