| 阻燃型硬质聚氨酯泡沫研究进展 摘要：硬质聚氨酯泡沫是一种保温隔热性能良好的泡沫材料，被广泛应用于各个领域。近年来，随着硬质聚氨酯泡沫塑料的应用愈加广泛，人们对它的阻燃性能也愈加重视。本文首先对阻燃剂的阻燃机理进行了概述，综述了近年来国内外阻燃型硬质聚氨酯泡沫的研究进展，包括含磷、含氮、复合和膨胀型等阻燃泡沫，最后对阻燃型硬质聚氨酯泡沫的市场前景进行了展望。 关键词：硬质聚氨酯泡沫；阻燃剂；阻燃机理 Research progress of flame retardant rigid polyurethane foam Abstract：Rigid polyurethane foam is a foam material with good thermal insulation properties and is widely used in various fields. In recent years, with the wider application of rigid polyurethane foam,the flame retardancy of the rigid polyurethane foam has been more and more important. In this paper, the flame retardant mechanism of flame retardants is summarized.The research progress of flame retardant rigid polyurethane foam at home and abroad in recent years is reviewed, including phosphorus, nitrogen, composite and expansion type flame retardant foam. Finally, the market prospect of flame retardant rigid polyurethane foam is prospected. Keywords: rigid polyurethane foam; flame retardant; flame retardant mechanism |
