摘　　要：通过热分析、红外光谱、剩碳率和氧指数对用含氮、磷等无机化合物处理后的阻燃木材的热降解行为进行了表征 ,并对其阻燃机理作了初步探讨 .结果表明 ,经过阻燃处理的木材其氧指数和剩碳率比未处理的木材升高 。The thermal degradation of wood treated with flame retardants containing P and N was studied by thermal analysis, infrared spectroscopy, chemical analysis, char yield and the limiting index (LOI). The thermal properties and retardant mechanism were also discussed. Experimental data showed that for the treated wood there was an increase in char yield and LOI, and decreases in activation energy and temperature of decomposition.
