Abstract

The present invention discloses a crack width adjustable water-based crack lacquer, which comprises a water-based primer and a water-based finish, and is characterized in that the water-based crack lacquer comprises the following components: the water-based primer comprising elastic resin, a film forming auxiliary agent, a defoaming agent, a thickening agent and water; the water-based finishing paint is prepared from colloidal silicon dioxide, nano zirconium oxide, superfine calcium carbonate, organic silicon resin, titanium dioxide, a thickening agent, a PH regulator, a dispersing agent, a wetting agent, polyethylene glycol, a defoaming agent, a coalescing agent and water. Colloidal silicon dioxide, nano zirconium oxide and superfine calcium carbonate crack in the drying and film forming process to form a continuous, uniform and fine crack texture, and the crack width can be adjusted by adjusting the adding amount of organic silicon resin.

Description

Technical field [0001] The present invention relates to the field of coating technology, specifically to a crack paint, in particular a water-based crack paint. Background [0002] Crack paint can form a good-looking crack on the surface of the object, which can not only achieve a protective effect, but also produce added value to improve the sense of beauty, so it is more and more favored by the public. [0003] Commonly used artistic crack paint is mainly a one-component nitro crack paint, usually by nitrifying cotton, pigments, resins, organic solvents and fillers and other components after grinding and modulation, through the volatile action of solvents to form cracks. China invention patent CN102675988A discloses a kind of nitro crack paint, comprising: 70-100 parts of alkyd resin, 80-100 parts of nitrified cotton, 180-250 parts of body pigment, 50-70 parts of matting powder, 20-30 parts of anti-settling agent, the nitrified cotton is added to the dispersion tank, add mixed ...
