| 摘 要： | 采用硅烷偶联剂（KH560）对三氧化二锑（Sb2O3）进行表面改性处理，并将其协效二乙基次磷酸铝（ADP）应用于聚酰胺6（PA6）阻燃研究。采用傅里叶变换红外光谱和热失重分析对改性Sb2O3进行表征，运用垂直燃烧、氧指数、锥形量热仪、热分析以及扫描电子显微镜和拉曼光谱等对阻燃PA6进行了阻燃性能及机理分析。结果表明，改性 Sb2O3与Sb2O3相比，与ADP具有更好的协同阻燃效应，其作用机制主要是在气相发挥阻燃作用；当ADP含量为8 %，改性Sb2O3含量为2 %时，阻燃PA6复合材料的UL 94等级达到V?0级，极限氧指数达到33.8 %。

| Abstract: | Antimony trioxide （Sb2O3） was modified with a silane coupling agent （KH560）， and then the synergistic flame retarding effect of Sb2O3 and aluminum diethylphosphate （ADP） on polyamide 6 （PA6） was investigated. The chemical structure and thermal performance of modified Sb2O3 was characterized by Fourier-transform infrared spectroscopy and thermogravimetric analysis （TG）. The flame-retardant performance and relevant mechanism of PA6-based composites were analyzed by vertical burning test， limiting oxygen index， and cone calorimeter analysis， TGA， SEM and Raman spectroscopy. The results indicated that the modified Sb2O3 exhibited a better synergistic flame-retardant effect than pristine Sb2O3. The flame-retardant PA6 composites achieved a UL 94 V-0 classification and a LOI of 33.8 vol% at a modified Sb2O3 content of 2 wt% and a ADP content of 8 wt%. |
