摘　　要：利用研制的防火液对木材进行阻燃处理，通过ＥＳＲ自旋捕捉技术和热分析仪考察其燃烧特性，对木材燃烧后长寿命自由基进行研究。实验结果表明，阻燃处理后木材的燃烧过程中长寿命自由基浓度下降，同时阻燃剂加速木材的热分解。Combustion and decomposition properties on wood treated by fireproofing solution were investigated by using the electron spin resonace (ESR) spin trapping technique and TG. The long lived gas phase radicals in comlbustion and decomposition products of wood were studied. It was shown that the concentration of radicals in combustion was reduced, and heat decomposition was accelerated and also there was a good flame retardant effect in wood treated by flame retardant.
