摘　　要：选取三类常见阴离子表面活性剂,硬脂酸、十二烷基硫酸钠和十二烷基苯磺酸钠,并以两两组合形式进行复配,重点研究阴离子复配改性剂对氢氧化镁阻燃剂的分散效果。经实验得到,十二烷基硫酸钠和十二烷基苯磺酸钠的复配组合改性效果最佳,并且在复配改性剂用量为6%,改性温度为70℃,改性时间为60 min时,达到最佳改性效果。利用激光粒度仪,测得改性后氢氧化镁颗粒的平均粒径约为1.9μm。Three common anion active agents including stearic acid, sodium lauryl sulfate and sodium dodecyl benzene sulfonate were combined in pairs. The dispersive effect of the anionic complex modifiers for magnesium hydroxide flame retardant was studied. According to the experimental results, the anionic complex modifier of sodium lauryl sulfate and sodium dodecyl benzene sulfonate has the best effect on magnesium hydroxide. Meanwhile, when the amount of the compound modifier accounts for 6%, the modified temperature is 70 ℃, the time is 60 min, the best effect will be achieved. By using laser particle size analyzer, the average particle size of the modified magnesium hydroxide particles is about 1.9 μm.
