Abstract

The invention discloses elastic waterproof paint for an exterior wall of a building. The elastic waterproof paint comprises, by mass, 55-60% of an acrylate waterproof emulsion, 1.5-1.8% of a dispersant, 1.0-1.2% of an antifoaming agent, 0.25-0.28% of a bactericide, 0.8-1.0% of an ultraviolet ray absorber, 0.15-0.3% of a film-forming assistant, 4.2-4.5% of dioctyl phthalate, 0.85-1.15% of ammonia water, 0.2-0.3% of a thickener AT-06 and the balance heavy calcium carbonate of 1250 meshes. The dispersant is acrylate copolymer carboxylate. The antifoaming agent is polyoxyethylene polyoxypropylene ether. The ultraviolet ray absorber is 2-hydroxy-4-n-octyloxybenzophenone. The film-forming assistant is glycol. The bactericide is benzisothiazolinone.

Description

A kind of external walls of building elastic water proofing paint

Technical field

The invention belongs to building material technical field, be specifically related to a kind of external walls of building elastic water proofing paint.

Background technology

Conventionally, buildings can be selected to whitewash with versicolor coating by External Wall, and such facade, because color and the gloss of coating have increased its aesthetic property, exists some problems also.Such as water tolerance and the weathering resistance of existing a lot of coating are bad, through rain drop erosion all the year round, will fade or replace through the summer of passing the winter, because the problem of expanding with heat and contract with cold, can cause coating surface occur be full of cracks and color comes off, the aesthetic property of building body is declined greatly, and the fragment dropping also can cause unsafe hidden danger.

Summary of the invention

The object of this invention is to provide a kind of external walls of building elastic water proofing paint, solved the problem that existing coating easily fades, comes off.

The technical solution adopted in the present invention is, a kind of external walls of building elastic water proofing paint, by mass percentage, formed by following component: 55%～60% acrylic ester waterproof emulsion, 1.5～1.8% dispersion agents, 1.0%～1.2% defoamer, 0.25%～0.28% sterilant, 0.8%～1.0% UV light absorber, 0.15%～0.3% film coalescence aid, 4.2%～4.5% dioctyl phthalate (DOP),, 0.85%～1.15% ammoniacal liquor, 0.2%～0.3% thickening material AT-06, surplus is 1250 order water-ground limestones, and above each component mass percent summation is 100%; Wherein, dispersion agent is acrylate copolymer carboxylate salt; Defoamer is polyoxyethylene polyoxy propyl alcohol amidogen ether; UV light absorber is Octabenzone; Film coalescence aid is ethylene glycol; Sterilant is BIT.

The invention has the beneficial effects as follows, the polyacrylic ester water-proof emulsion adopting has outstanding low temperature flexibility, excellent tensile strength, fabulous water tolerance, alkali resistance, weathering resistance, with other composition collocation, make that coating of the present invention has good waterproof performance, second-order transition temperature is low, frost resistance is good, the advantage that weathering resistance is strong, existing coating water-proof and weathering resistance deficiency are overcome, the shortcoming of easily fading and coming off.

Embodiment
