Study on fire protection effect of fire-retardant coating on wood structure model
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.
