摘要:
为研究软质聚氨酯泡沫（FPUF）的燃烧行为对火灾的影响，采用锥形量热仪（CONE）分析FPUF在强制点火和非强制点火模式下的燃烧行为、热释放速率HRR、质量损失速率MLR和燃烧效率η。研究结果表明：当外部辐射≥40 kW/m2时，FPUF在2种点火模式下燃烧的HRR和MLR均出现2个明显的峰值且η约为88%；当外部辐射<40 kW/m2时，FPUF在非强制点火模式下燃烧的HRR和MLR曲线趋于单峰形式；FPUF在强制点火模式下燃烧前期为异氰酸酯（TDI）和多元醇的混合燃烧，在非强制点火模式下为TDI的挥发。根据研究结果修正现有燃料组分的热值计算方法，获得FPUF和多元醇的热值分别为（20±2），（28±3） kJ/g。
Abstract:
To study the influence of the combustion behavior of flexible polyurethane foam (FPUF) on fire,the combustion behavior,heat release rate (HRR),mass loss rate (MLR) and combustion efficiency (η) of FPUF under the piloted ignition and non-piloted ignition modeswere analyzed by using cone calorimeter (CONE).The results showed that when the external radiant heat flux was greater than or equal to 40 kW/m2,both the HRR and MLR curves of FPUF combustion under two ignition modes presented two obvious peaks,and the was about 88%.When the external radiant heat flux was less than 40 kW/m2,the HRR and MLR curves of FPUF combustion under the non-piloted ignition modetended to be the single peak form.The pre-combustion of FPUF under thepiloted ignition mode was the mixed combustion of isocyanate (TDI) and polyol,and it was the volatilization of TDI under the non-piloted ignition mode.The existing calculation method for the calorific value of fuel components was revised according to the research results,and the calorific values of FPUF and polyol were calculated to be （20±2） and （28±3） kJ/g,respectively.
