摘　　要：利用氧指数测定仪和锥形量热仪,研究不同质量分数FRW阻燃剂浸渍杨木素板和饰面炭化杨木单板的阻燃性能。结果表明,质量分数8%以上FRW阻燃剂浸渍处理的炭化杨木单板阻燃性可达到日本标准JISD1322-77中规定的难燃一级品标准;随着FRW阻燃剂浸渍质量分数的增加,阻燃炭化杨木单板的热释放速率、总热释放量、烟比率和总烟释放量均呈降低趋势,说明阻燃炭化杨木单板具有较佳的阻燃和抑烟性能。Oxygen index chamber and CONE calorimeter were used to evaluate the fire-retarding properties of FRW fire-retardant carbonized poplar veneers which were dipped with different consistence.The results showed that：the fire-retarding property of FRW fire-retardant carbonized poplar veneers which were dipped with more than 8% consistence could reach the first class of JISD 1322 -77.The heat release rate （HRR）,total heat release （THR）,smoking ratio （SR）and total smoke production （TSP）of FRW fire-retardant carbonized poplar veneers showed the decreasing tendency with the increase of the dipping consistence.The FRW fire-retardant carbonized poplar veneer owned the better fire-retarding and smoke suppression performance.
