摘　　要：为了分析不同类型面料及填料对软垫家具火灾特性的影响,在ISO 9705标准小室(3.6 m×2.4 m×2.4 m)内对不同面料和填料的软垫家具进行了全尺寸火灾模拟实验.实验中采用的样品为具有相同外形、尺寸、框架的软垫家具,测量了热释放速率、CO和CO2的生成量、CO生成率等相关的火灾动力学参数,给出了CO/CO2的质量比值、CO的生成率、热释放速率三者之间的关系.研究结果表明:填料在软垫家具火灾中是燃烧的主体,但它对软垫家具火灾特性影响比面料小.The research aimed at predicting the behavior of upholstered furniture in fires and the hazards produced during their burning. Experiments were conducted on ten identical style chairs inside the ISO 9705 room （3.6 m×2.4 m×2.4 m）. Different types of cover and foam were used for each chair with the same size, shape and frame. Heat Release Rate, the mole fractions of carbon monoxide, and carbon dioxide inside the exhaust duct were studied. From the experiments it was found that each type of cover and foam presented different fire hazards, the effects of fabric on fire behavior of upholstered furniture were greater than those of foam. But each of them had a rapid-fire growth. The linear relationships among the ratio CO/CO2, heat release rate, CO production rate were also presented. The results will provide references for building fire protection and fire safety design.
