| 摘 要： | 通过热分析、剩碳率、氧指数和扫描电镜对无机金属氧化物溶胶处理后的羊毛样品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，经过阻燃处理的羊毛其氧指数、剩碳率比未处理的羊毛升高，阻燃性明显增强。

| Abstract: | The flame retardant mechanism of wool was obtained by treating pure wool with metal oxide sol-gel system. The flame retardance and thermal stability of it were studied by thermal analysis, SEM, limited oxygen index (LOI) and char yield methods. The results showed that metal oxide composing on the wool fiber surface, changing the process of thermal degradation, improving the flame retardance of the wool. |
