摘　　要：采用大尺度实体火试验方法,综合分析比较了岩棉、B1级聚氨酯、B1级聚苯乙烯彩钢复合夹芯板建筑体的试验现象、火焰蔓延特性、环境温度等燃烧特性试验数据。结果表明,岩棉芯材彩钢复合夹芯板相对安全,聚氨酯芯材彩钢复合夹芯板建筑体因板缝拼接处采用可燃软质泡沫存在安全隐患,聚苯乙烯芯材彩钢复合夹芯板在试验过程中出现全面燃烧,火灾危险性很大。Using large-scale real fire test, test spread and environmental temperature of rock polyurethane and B1 grade polystyrene colored steel fire grade sandwich panel building were compared and analyzed. The resuits showed that rock wool cored was comparatively safe, PU cored might not be safe because of using combustible soft foam at seam stitching, polystyrene cored bured comprehensively and was of high fire risk.
