密胺（MF）泡沫具有优异的本征阻燃性能,燃烧时火焰易自熄且不产生流滴,用于保温、吸声等材料具有广阔的前景,但是较大的脆性限制了其广泛的应用。文章探讨了不同发泡方式下泡沫的形貌特征及力学性能差异,不同发泡剂对泡沫形貌的影响,并讨论了韧性较强的聚乙烯醇（PVA）的引入对泡沫性能的影响,并对其阻燃、力学及导热性能等通过极限氧指数（LOI）、压缩和热导率进行了测试分析。
Melamine formaldehyde(MF) foam is one autologous fire-retardant material which can be easily self-extinguished without producing toxic drips during combustion,it can be used as thermal insulation and sound-absorption material and has a bright future.However,the shortcomings such as large fragility restrict its wider application.In this paper,we discussed the differences between morphology and compressive modulus in different ways of foaming and then the influence on foam morphology of foaming agent as well as the effect on the properties with the addition of PVA which has good flexibility,then analyzed its fire-retardant,mechanics and thermal insulation properties using LOI,compression and coefficient of thermal conductivity test respectively.
