Abstract

White substances are easily generated on surfaces of concrete and cement mortar products, and the phenomenon is whiskering. A main ingredient in concrete is calcium silicate, and is subjected to hydration reaction after contacting with water, so as to form free calcium, silicic acid and hydroxyl; water diffuses to the surface of a wall body under the action of capillary pressure; the substances such as free calcium, sodium and potassium are migrated to the surface of the wall body by taking water as a carrier, and are left on the concrete surface to form white powdery crystal along with evaporation of water after reaching the concrete surface, or the substances react with carbon dioxide in air to crystallize on the concrete surface and form a white hard block; and the forming of the white substances is concrete whiskering. The white substances are stubbornly left on the concrete surface for a long period of time under certain conditions; the color uniformity of the concrete surface is destroyed; and the concrete building surfaces are certainly damaged. The invention provides a damp-proof and whiskering-proof paint for a concrete wall space and a preparation method. The paint is non-toxic and odorless, belongs to an environment-friendly material, and is good in damp-proof and whiskering-proof effects.

Description

technical field [0001] The invention belongs to the class of chemical coatings, in particular to a special moisture-proof and anti-pan-alkali paint for concrete walls and a preparation method thereof. technical background [0002] In daily life, we often see that there are many gray-white loose substances on the walls of buildings, especially the walls of toilets. This is the so-called pan-alkali phenomenon. Accompanied by moisture. Pan-alkali can cause wall paint to bulge, crack or fall off, and sometimes make the color of the colored paint dull, white or fade; pan-alkali may also make the base cement mortar gray become loose and everted; pan-alkali seriously affects the appearance of buildings, Moisture damage to building walls is a common problem in industrial and civil buildings, which seriously affects people's health and the service life of building structures. With the development of the construction industry, for concrete buildings and decorative concrete products,...
