摘　　要：用四氯化钛、氟化氢铵和有机二酸组成的阻燃体系对羊毛纤维进行阻燃处理,所得的羊毛纤维用热分析、剩炭率、扫描电镜(SEM)和氧指数等分析方法对其阻燃性能进行了研究,用Kissinger方程计算热降解反应活化能,DTA-TG从室温至700℃,结果表明:经过四氯化钛、氟化氢铵和有机二酸组成的阻燃体系处理的羊毛纤维剩炭率、氧指数均比未经阻燃处理的羊毛纤维有所提高,热降解温度下降.The thermal property of wool treated by the flame-retaxdaant synergistic system, Titanium tetrachloride,Ammonium bifluoride and dicarboxylic acids,was studied by thermal analysis,char yield,scanning electron microscopy(SEM)and t11e limiting oxygen index(LOI). The activation energy of thermal degradation was obtained by using the equation of Kissinger in thermal analysis from ambient temperature to 700℃.The wool treated with flame-retardant reagents shows increases in LOI.char yield and activation energy,and decrease in the temperature of decomposition,comparing with the untreated woo1.
