摘要(Abstract)：

以三氯化锑和针状硅灰石为原料,通过水解反应制备了硅灰石/三氧化二锑(Ca Si O3/Sb2O3)复合粒子,研究包覆量、反应温度、表面活性剂等工艺条件对包覆效果的影响。利用SEM、XRD、FT-IR和XPS等测试技术表征了复合材料的断面形貌、Sb2O3的物相、形貌及其在硅灰石表面上的包覆行为。用Ca Si O3/Sb2O3复合粒子替代传统的三氧化二锑(Sb2O3)与十溴二苯乙烷(DBDPE)复配对聚酰胺6(PA6)进行阻燃性研究,研究Ca Si O3/Sb2O3替代Sb2O3后的分散情况,以及对材料阻燃性能和力学性能的影响。实验结果表明,控制三氧化二锑包覆量为51%,反应温度为40℃,表面活性剂PEG20000添加量为1.0%,可以实现三氧化二锑以超细粒子形式包覆在硅灰石表面。Ca Si O3/Sb2O3在PA6中具有较好的分散性。以Ca Si O3/Sb2O3代替Sb2O3所得的复合材料阻燃,抑烟性能良好,垂直燃烧达到V-0级,力学性能显著提高。
