摘　　要：对常用外保温材料PU、XPS和EPS在堆垛火情况下进行灭火试验,试验在环境风速小于2 m/s的场所中进行。通过灭火剂直接喷射,获得ABC类干粉、直流水、水凝胶混合液和A类泡沫对不同保温材料的灭火和冷却效果。PU具有较XPS和EPS更短的引燃时间。对于PU堆垛火,干粉灭火剂和水具有较好的灭火性能。对于EPS堆垛火,水凝胶的灭火效果较好。外保温材料燃烧后应优先利用固定消防设施快速出水,控制火势。Fire extinguishing tests of commonly used exterior thermal insulation materials PU, XPS and EPS stacking was carried with wind speed less than 2 m/s. The ABC powder, direct current water, mix liquid of water gel and type A foam mix liquid were spray directly on the stacking for obtaining the ex- tinguishing fire effect and cooling performance of different ma- teria. Powder extinguishing agent and direct current water had a better fire extinguishing performance on PU stacking, while water gel was good for EPS. The fire of thermal insulation materials could be dealt in preference of water from fixed fire control facilities.
