摘　　要：以氯化镁和碳酸铵为主要原料,以PEG-2000为表面活性剂,采用均匀沉淀法制备了纳米氧化镁(Mg O)。采用XRD、TEM、激光粒度仪、水化法等手段对纳米Mg O进行了表征,并检测了纳米Mg O对PBT的增韧与阻燃效果。结果表明:在适当的工艺条件下获得了65.3 nm的Mg O颗粒,Mg O最高活性达到96.15%,合成的纳米Mg O对PBT的阻燃效果良好,并对基体有增强作用。Nano-magnesium oxide was prepared with homogeneous precipitation method using magnesium chlo-ride and ammonium carbonate as main raw materials while PEG-2000 as surfactant.The MgO was characterized by means of XRD,TEM,Laser particle size instrument,hydration reaction.The toughening effect and flame retardant effect of nano-magnesium to PBT were also measured.The results show that MgO particles of 65 .3 nm could be ob-tained under suitable processes.The surface activity of MgO reaches to 96.15%.The synthesized nano-magnesium oxide has good flame retardant effect to PBT and play toughing role to it.
