Abstract

The invention specifically relates to water-based lotus-leaf-structured hydrophobic over-printing varnish for wallpaper and a preparation method of the over-printing varnish, and belongs to the technical field of ink. The technical problem to be solved is to provide an over-printing varnish by using which the surface of a wallpaper product can be smooth, bright and wear-proof and the lotus leaf type waterproof and moisture-roof effects can be realized, and a preparation method of the over-printing varnish. In order to solving the technical problem, the technical scheme adopted is as follows: the water-based lotus-leaf-structured hydrophobic over-printing varnish for the wallpaper is prepared from raw materials including a modified organic silicon polymer emulsion, a non-film-forming acrylate emulsion, an styrene-acrylic emulsion, neutralizing amine, propylene glycol, a water-based coalescing agent, a water-based leveling wetting agent, a mineral defoamer, a water-based nanoscale organosilicon waterproofing agent, a waterborne polyurethane thickening agent, deionized water and an organic silicon defoamer; the raw materials are stirred and mixed in a specific order to form the over-printing varnish.

Description

technical field [0001] The invention specifically relates to a water-based lotus leaf hydrophobic varnish for wallpaper and a preparation method thereof, belonging to the technical field of inks. Background technique [0002] At present, most of the water-based inks for wallpaper printing on the market use non-film-forming acrylic emulsion and a small amount of film-forming ink to ensure that the product can meet the requirements of high-temperature curing and drying to form a film, so that the product does not have the problem of poor high-temperature anti-sticking. It is made of emulsion compound, and the printing process itself requires not to use a large amount of raw materials containing silicone, so as not to affect the recoatability and printing suitability, which makes the wallpaper product not achieve a good waterproof effect. When the wallpaper product is decorated to When it is on the wall, affected by the humid environment, the service life of the wallpaper will ...
