Abstract

The invention relates to a waterproof elastic coating material, which comprises, by mass, 0.5-1% of a dispersant, 0.3-0.8% of an antifoaming agent, 0.15-0.3% of an anti-mildew gent, 0.5-0.8% of an ultraviolet ray absorption agent, 0.6-0.8% of a film forming auxiliary agent, 3.8-4.2% of dioctyl phthalate, 45-50% of 1250 mesh heavy calcium carbonate, 0.5-0.8% of ammonia water, 0.10-0.3% of a thickening agent AT-06, and the balance of an acrylate waterproof emulsion, wherein the dispersant is polyethylene glycol, the antifoaming agent is polyoxyethelene polyoxypropylene pentaerythritol ether, the ultraviolet ray absorption agent is 2-hydroxy-4-n-octyloxy-benzophenone, and the film forming auxiliary agent is 2,2,4-trimethyl-1,3-pentanediolmono(2-methylpropanoate) or ethylene glycol. With the waterproof elastic coating material, the problems of poor water resistance, poor weathering resistance, easy fading and easy shedding of the existing coating material are solved.

Description

A kind of water-proof elastic dope

Technical field

The invention belongs to building material technical field, be specifically related to a kind of water-proof elastic dope.

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 water-proof elastic dope, solved the problem that existing coating easily fades, comes off.

The technical solution adopted in the present invention is, a kind of water-proof elastic dope, by mass percentage, formed by following component: 0.5%～1% dispersion agent, 0.3%～0.8% defoamer, 0.15%～0.3% mould inhibitor, 0.5%～0.8% UV light absorber, 0.6%～0.8% film coalescence aid, 3.8%～4.2% dioctyl phthalate (DOP), 45%～50%1250 order water-ground limestone, 0.5%～0.8% ammoniacal liquor, 0.10%～0.3% thickening material AT-06, surplus is acrylic ester waterproof emulsion, above each component mass percent summation is 100%; Wherein, dispersion agent is polyoxyethylene glycol; Defoamer is polyoxyethylene polyoxypropylene tetramethylolmethane ether; UV light absorber is Octabenzone; Film coalescence aid is 2,2,4-trimethylammonium-1,3-pentanediol mono isobutyrate or ethylene glycol.

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 water-proof elastic dope 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
