采用浸泡法制得了憎水剂改性膨胀珍珠岩，以此为基础，通过调整质体比和加入防水剂，研究了膨胀珍珠岩保温砂浆吸水率、强度和干密度的变化规律。试验结果表明：通过有机硅憎水剂对膨胀珍珠岩表面改性，可以把珍珠岩的吸水率从290％降低到90％；随着质体比的减小，砂浆的吸水率增大，强度和干密度减小；在选择最优质体比的基础上，加入珍珠岩专用防水剂，可进一步降低膨胀珍珠岩保温砂浆的吸水率。

Hydrophobe modified expangded perlite were prepared by soaking method. The change law of water absorption,compressive strength and dry density of perlite thermal insulation mortar were investigated by the change of mass-volume concentration and the ad-dition of waterproof agent,basing on the modification of expanded perlite. The results show that the water absorption of perlite can be decreased from 290%to 90%when the surface of expanded perlite is modified by silicone water-proofing agent. With the decreasing of mass-volume concentration,the water absorption of perlite insulation mortar increases,the compressive strength and dry density de-crease.The water absorption of perlite insulation mortar can be decreased further by adding water-proofing agent for perlite,supposing the optimal mass-volume concentration is selected.
