摘　　要：氢氧化镁具有缓冲性、活性大、吸附能力强等优点,与其他强碱相比,得到了更广泛的关注。近年来,随着环保意识的增强,无毒、高效、抑烟的无机阻燃剂,尤其是Mg(OH)2阻燃剂越来越受到重视。本研究对国内外制备纳米氢氧化镁的研究现状做了综述,较详细地介绍了直接沉淀法、水热反应法、沉淀-共沸蒸馏法、反向沉淀法、激光烧蚀法、微波合成法、液-固相电弧法、表面剂诱导法、超重力技术制备法和常温固相法等制备方法。Magnesium hydroxide has the advantages of buffering, great activity and strong capacity, and therefore, has attracted more attention than other strong alkalis. With the increase of people＇s consciousness of environment protection, innocuous, highly effective and smoke-depressing inorganic flame retardants, especially magnesium hydroxide flame retardant, have been attached great importance to. The paper reviews the status quo of the research on the preparation of both foreign and domestic nanometer magnesium hydroxide and presents in detail the preparation methods including direct precipitation, hydrothermal reaction, precipitation-azeotropic distillation, pulsed-laser ablation, reversed precipitation, microwaveassisted synthesis, liquid-solid arc discharge, surfactant-induced solution, supergravity technology and normal temperature solid phase.
