摘　　要：研制的酚醛泡沫塑料的氧指数、压缩强度、导热系数随密度呈现不同的变化趋势，氧指数、压缩强度随密度的增大而增大，导热系数在１００ ｋｇ／ ｍ ３ ～２００ｋｇ／ ｍ ３ 内达到最小值。酚醛泡沫的热稳定性优于聚氨酯泡沫和聚苯乙烯泡沫相应性能。The devoleped phenolic foam′s oxygen index,compression strength and thermal conduct coefficient vary differently with density.The oxygen index and the compression strength inhance with the increasing of density.The thermal conduct coefficient gains its minimum value when the density is within 100kg/m 3-200kg/m 3.The heat stability of the developed phenolic foam is better than that of polyurethame foam and polystyrene foam.
