Problems solved by technology

The principle is to use acidic solution to clean and neutralize alkaline objects, which is a low-cost and easy-to-operate method, but this method cannot fundamentally solve the pan-alkaline problem. After a period of time, new pan-alkali will accumulate on the problem wall again. Alkali

Abstract

The invention relates to an alkali-resistant impermeable waterproof slurry, which comprises a surface layer slurry and a bottom layer slurry, wherein the bottom layer slurry comprises powder A and a liquid agent, and the surface layer slurry comprises powder B and a liquid agent; the powder A comprises slag cement, a resin efflorescence inhibitor, blast furnace slag, silicon powder and an organicsilicon water repellent agent; the powder B comprises aluminate cement, a resin efflorescence inhibitor, blast furnace slag, silicon powder and an organic silicon water repellent agent; and the liquidagent comprises a silicon resin emulsion. The invention further provides a waterproof material with salt and alkali resistance and a construction process of the waterproof material. The waterproof slurry prepared in the invention has the characteristics of wet base surface construction, high early strength and good impermeability, and has excellent efflorescence resistance compared with other traditional wall waterproof materials.

Description

technical field [0001] The invention relates to the field of slurry, in particular to a waterproof material with anti-alkali and anti-seepage and a construction process thereof. Background technique [0002] After the concrete mortar building has been used for a period of time, under the dry-wet cycle environment, the base layer seeps or returns to moisture, and the wet mortar wall will precipitate or dissolve soluble saline and alkali, which will seep out with the water movement of the wall, and the saline-alkali The ingredients will accumulate on the surface of the wall, forming the phenomenon of efflorescence. The efflorescence of the building wall is a chronic disease among the wall diseases. It will cause the wallpaper or paint on the wall to bulge, crack, fall off, etc., resulting in water seepage after a period of use, and affecting the quality of home life and people. Healthy body. [0003] The phenomenon of efflorescence salting-out is essentially a chemical weath...
