摘要：

通过化学复合法制备出了油酸包覆纳米片状形貌Al(OH)3/Mg(OH)2复合阻燃剂.SEM结果表明，通过改变铝镁摩尔比可制备出不同形貌的片状复合阻燃剂.X射线衍射(XRD)结果表明，复合阻燃剂以Al(OH)3为基体，表面成功包覆Mg(OH) 2.红外光谱(IR)结果表明，油酸以羧酸盐形式成功包覆在复合阻燃剂的表面.X射线能谱(EDS)和热重分析(TG)结果表明，油酸均匀包覆，同时Al(OH)3和Mg(OH)2按接近反应原料的配比很好地进行复合；热重分析(TG)和差热分析(DTA)表明，复合阻燃剂相对于Al(OH)3、Mg(OH)2、Al(OH)3和Mg(OH)2机械混合样，阻燃性能有显著提高.

Abstract:

The nanosheet Al(OH)3/Mg(OH)2 composite retardant coated with oleic acid is synthesized through chemical compounding technique. The SEM result indicates that through changing the ratio of aluminum and magnesium can different morphology nanosheet composite retardant be prepared. The XRD result indicates that composite retardant is based on Al(OH)3, whose surface is coated with Mg(OH)2. The IR result indicates that composite retardant is coated with oleic acid by way of carboxylic acid salt. The EDS and TG result indicates that oleic acid is coated well-distributed, while Al(OH)3 and Mg(OH)2 are compounded near the ratio of reactant. The thermal analysis (TG and DTA) result indicates that compared with Al(OH)3, Mg(OH)2, and the physical mixture of Al(OH)3 and Mg(OH)2, flame retardancy of composite retardant is greatly improved.

Key words: composite flame retardant; aluminum hydroxide; magnesium hydroxide;  nanosheet; chemical compound; oleic acid
