摘　　要：利用聚二甲基硅氧烷类有机硅憎水剂对小粒径膨胀珍珠岩进行了改性,讨论了改性剂用量、改性干燥时间、改性干燥温度对改性效果的影响。结果表明,最佳改性条件为改性剂用量1.5%、改性干燥时间2h、改性干燥温度200℃,并用红外光谱法对其进行了表征。Small size particle expanded perlite is modified by the hydrophobic agent of polydimethylsiloxyl silicone. The effect of surface modification results show that the optimal modification 1.5 %, 2 h and 200 ℃, respectively. This is studied on modifier amount, conditions of modifier amount, modified time and temperature. modified time and temperature perlite is characterized using infrared spectroscopy.
