AI Technical Summary

Problems solved by technology

[0002] In the current existing technology, external wall cracking, external wall seepage, external wall efflorescence, and mildew are the current status of external walls. According to the current traditional process of external wall coating, external wall waterproof coating, external wall putty, external wall Wall alkali-resistant primer, exterior wall paint and exterior wall finish paint, etc., use many materials, complex processes, and high construction requirements. Therefore, there are many quality problems in the current exterior wall coating: cracking, water seepage, efflorescence, and peeling. etc., and the cost is high and the construction period is long

Abstract

The invention discloses waterproof, mildewproof, alkali-resistant and crack-resistant exterior wall paint applied directly onto cement base surface. The exterior wall paint comprises the following components in a weight ratio: a component A: water, a thickener, a dispersant, a defoaming agent, a film-forming additive, a bactericide, a wetting agent, a solvent, and a pH value regulator; a componentB: rutile titanium dioxide, barium sulfate, and a filler; a component C: a polyurethane thickener, the solvent, the water, the defoaming agent, and an emulsion; a component D: the bactericide, the water, an anti-fouling additive, an antirusting agent, and a mildewproof and anti-algae agent; the waterproof, mildewproof, alkali-resistant and crack-resistant exterior wall paint can be applied directly onto the cement base surface, is free of water prevention, and does not need putty or a primer, and the waterproof and alkali-resistant exterior wall paint can cover small cracks without finishingpaint; the waterproof and alkali-resistant exterior wall paint is simple to construct, excellent in quality, long in service life, low in VOC, environmentally friendly, and healthy, saves labor, reduces cost, and can be used indoors and outdoors and used for wall renovation and tile renovation.
