Abstract

The invention discloses crack-resistant cement-based water-proof paint and belongs to the technical field of water-proof paint. The paint is prepared from, by weight, 22-26 parts of cement, 33-37 parts of silica sand, 15-17 parts of calcium carbonate, 10-12 parts of fly ash, 5-7 parts of hydrophobic organic silicon powder, 3-5 parts of zinc oxide, 6-8 parts of titanium dioxide, 1-3 parts of carboxymethylcellulose, 4-6 parts of melamine polyphosphate, 11-13 parts of neoprene latex, 7-9 parts of silicone acrylic emulsion, a proper amount of water, 1-3 parts of defoaming agent, 1-2 parts of water reducing agent, 1-2 parts of early strength agent, 0.5-0.8 part of preservative, 2-4 parts of wetting agent and 1-2 parts of dispersing agent. The invention further discloses a preparation method of the crack-resistant cement-based water-proof paint. The pain is easy to prepare, good in water-proof ability, good in adhesive ability and long in service life.

Description

technical field [0001] The invention relates to the technical field of waterproof coatings, in particular to a crack-resistant cement-based waterproof coating and a preparation method thereof. Background technique [0002] In some low-strength bases, the traditional method is to pour cement concrete inside and outside the surface and underground or masonry, and then after the cement concrete is cured, level it with cement mortar, and then apply waterproof coating, and then Then make a protective layer on the waterproof coating, but the traditional cement-based waterproof coating has low bonding strength, and it is easy to crack and detach between the concrete base and the waterproof layer, and it is easy to fall off and touch hard objects (such as: Red bricks, gray knives, steel heads, etc.), are also prone to cracking and falling off, seriously affecting the service life and waterproof effect. The surface of the original waterproof layer is smooth, especially when doing wa...
