摘　　要：采用司班80表面活性剂对超细氢氧化铝粉体(ATH)进行了湿法改性,通过X射线衍射仪(XRD)、红外光谱分析仪(FT-IR)、紫外分光光谱仪(T9CS)等表征,分析了改性工艺条件对氢氧化铝粉体性能的影响。结果表明,司班80改性剂用量为1%、温度为70℃、搅拌速率为600 r/min、改性时间为35 min时,改性后氢氧化铝粉体的活化指数可以达到97.8796%、吸光度(Abs)可达2.748、吸油值可低至35.2 mL/100g,改性效果较好。司班80改性后氢氧化铝粉体的粒径分布变得更加均匀,颗粒表面的润湿性由亲水疏油转变为亲油疏水,可以完全漂浮在去离子水上。The ultrafine aluminum hydroxide powder(ATH)was wet-modified with Sipan 80 surfactant by X-ray diffractometer(XRD),infrared spectroscopy(FT-IR)and ultraviolet spectrometer(T9CS).The characteristics of the modified process conditions on the properties of aluminum hydroxide powder were analyzed.The results show that the activation index of the modified aluminum hydroxide powder can reach 97.8796%when the dosage of Sipan 80 modifier is 1%,the temperature is 70℃,the stirring rate is 600 r/min,and the modification time is 35 min.The absorbance(Abs)can reach 2.748,the oil absorption value can be as low as 35.2 mL/100g,and the modification effect is better.After the modification of the Sipan 80,the particle size distribution of the aluminum hydroxide powder becomes more uniform,and the wettability of the surface of the particle changes from hydrophilic oleophobic to oleophilic hydrophobic,which can completely float on the deionized water.
