摘　　要：为研究防火涂料对木结构建筑的防护效果,提升古建筑在火灾中的安全性,本文通过搭建缩尺寸模型进行对比试验。研究不同火源工况下,有无防火涂料在火蔓延、温升特性及灼烧痕迹方面的差异。与油盘火源相比,木垛火源引燃周围木板所需的时间更长。防火涂料在延缓火势蔓延、降低复燃概率及减小火焰灼烧面积方面均有显著效果。试验为改进和完善古建筑消防安全中被动防火技术的应用提供了基础数据及参考。In order to obtain deeper insights into the protective ef-fect of fire-retardant coating on historic buildings with wooden structures and to improve the overall fire safety,this paper carried out comparative experiments by constructing a reduced-size wooden model.The differences in fire spread,temperature rise characteristics and burn marks with and without fire-retardant coating under different fire conditions were investigated.Com-pared with the oil pool fire,it takes longer time for the wood stack fire source to ignite the surrounding wooden boards.Fire-retardant coating was effective in slowing down the rate of fire spread,reducing the probability of re-ignition and minimizing the area burned by the flames.These experiments provide basic data and important references for the improvement and refinement of the application of passive fire protection technology in the fire safety of the historic buildings.
