摘要:以氯化镁和氨水为原料,聚乙二醇6 000为分散剂,利用直接沉淀法合成了粉末状、粒度均匀且分散性好的纳米氢氧化镁.研究了分散剂用量,反应时间,反应温度,反应物配比等对氢氧化镁颗粒平均粒径的影响,并采用红外光谱(FTIR)、X射线衍射(XRD)、扫描电镜(SEM)对颗粒结构进行表征.结果表明,制备纳米氢氧化镁的最优工艺条件为:分散剂聚乙二醇6 000浓度为1.50 g/mol MgCl2,反应时间30 min,反应温度35℃,MgCl2和氨水的摩尔比为1∶3.
Magnesium hydroxide with nanometer level,powder shape,even particle size and fine dispersion is synthesized by direct precipitation method with magnesium chloride and ammonia as raw materials and PEG 6 000 as dispersant.Effects of the concentration of PEG 6 000,reaction temperature,reaction time,molar ratio of reactants on the mean particle size of Mg(OH) 2 particles are studied and morphological structure of the particle is characterized by Fourier transform infrared spectroscopy(FTIR),X-ray diffraction(XRD) and scanning electron microscopy(SEM).The results show that the optimum conditions for preparing nanometer magnesium hydroxide are as follows: the concentration of PEG 6 000 is 1.50g/mo lMgCl2,reaction time is 30 min,reaction temperature is 30 ℃,molar ratio of reactants is 1∶3.
