摘要 采用聚酰亚胺(PI)预聚法,以高岭土(Kaolin,KL)和聚磷酸铵(APP)为阻燃剂,合成KL/APP阻燃硬质聚氨酯-酰亚胺(PUI)泡沫塑料。分析KL/APP的添加量和配比对氧指数、烟密度、炭层形貌、表观密度及力学性能的影响。结果表明:随着KL/APP复配阻燃剂添加量的增加,硬质PUI泡沫塑料的氧指数、表观密度、压缩强度、压缩模量以及表面粉化程度均增加,且密度指数分别为1.999和1.764;烟密度随着KL含量的增大而减小,KL/APP阻燃剂能改善泡沫炭层疏松多孔的缺点。

Abstract:PI pre-polymerization method was adopted to synthesize the rigid polyurethane-imide (PUI) foams flame retarded by kaolin(KL) and APP. The effect of content and ratio of KL/APP on the limited oxygen index, smoke density rank, char layer morphology, density and mechanical properties was analyzed. The results show that with the increase of content of KL/APP, the limited oxygen index, density,compressive strength and modulus and surface chalking degree of the rigid polyurethane-imide foams increase. The density exponent values for compression strength and compression modulus are fitted respectively as 1.999 and 1.764; while the smoke density rank of foams decreases with the increasing addition of KL. Moreover, the disadvantage of porous char layer of foams can be improved with the addition of KL/APP.
