摘　　要：本文讨论了从硼泥制备氢氧化镁阻燃剂工艺的适宜条件和影响因素,制得的氢氧化镁纯度>94％,比表面积<20m^2/g,平均粒径1μm～2μm,应用试验表明其具有优良的阻燃和消烟性能。In this experiment,magnesium hydroxide as flame retardant has been prepared from the slurry of borax,and the optimal conditions which influence the experimental results have been discussed and determined. The magnesium hydroxide has (1) a purity greater than 94% , (2) a specific surface area (BET) less than 20m2/g, (3) an average diameter of about lμm-2μm,and (4) good flame retardancy and excellent smoke suppression character.
