Water-based paint for heels of leather shoes

Abstract

The invention discloses water-based paint for heels of leather shoes. The water-based paint comprises the following components in percentage by weight: 10 to 20 percent of deionized water, 1 to 5 percent of propylene glycol, 1 to 3 percent of alkali associative thickener, 1 to 3 percent of alcohol ester 12 film-forming aid, 0.01 to 0.05 percent of non-silicone mineral oil system defoamer, 50 to 75 percent of water-based acrylic emulsion ( of which the grain diameters are 3 to 10 micrometers), 5 to 20 percent of water-based acrylic emulsion (of which the grain diameters are 40 to 90 nanometers), 0.05 to 0.2 percent of dimethylethanolamine (a pH regulator), 3 to 8 percent of resin-free water-based color paste and 0.01 to 0.5 percent of BYK348 leveling agent. According to the water-based paint, the main raw materials belong to a water-based system, and in a formula, a toxic and organic solvent is avoided. By the water-based paint, a film is formed on micrometer acrylic resin preferentially, and nanometer resin forms small bulges with microcrystal structures on the basis of the micrometer acrylic resin paint film, so that a self-cleaning structure which is similar to the surfaces of lotus leaves is formed on the surface of the integral pain film.

Description

technical field [0001] The invention relates to a water-based paint, in particular to a water-based paint used for leather shoe heels. Background technique [0002] At present, most of the heels of leather shoes are mainly made of ABS plastics, and the heels are formed by injection molding. Because there are bad surface defects such as silk marks and mold marks on the surface of plastic injection molding, and at the same time, the exposed plastic surface is prone to aging and fading. Spraying with traditional solvent-based paint, because the paint contains a large amount of toxic organic solvents such as toluene, xylene, and banana water, all of which evaporate during the painting process, endangering health, causing paint occupational diseases, and polluting the air environment. The population has reached 7 billion. Today, according to 3 billion pairs of heels per year, and 5 grams of solvent is volatilized when each pair of heels is painted, 150,000 tons of solvents will ...

Because there are bad surface defects such as silk marks and mold marks on the surface of plastic injection molding, and at the same time, the exposed plastic surface is prone to aging, fading and other defects.

Spraying with traditional solvent-based paint, because the paint contains a large amount of toxic organic solvents such as toluene, xylene, and banana water, all of which evaporate during the painting process, endangering health, causing paint occupational diseases, and polluting the air environment. The population has reached 7 billion. Today, based on 3 billion pairs of heels per year, and 5 grams of solvent is volatilized when each pair of heels is painted, 150,000 tons of solvents will volatilize into the air every year due to heel painting, seriously polluting the air environment.

At the same time, the traditional ordinary paint spraying has poor water resistance, especially when walking in rainy days, water droplets, dust, etc. are easily adsorbed on the surface of the paint film, which affects the overall appearance of the shoes
