Water-based chromium-free fingerprint-resistant paint for galvanized steel plate

The invention discloses water-based chromium-free fingerprint-resistant paint for a galvanized steel plate. The paint comprises raw materials in parts by weight as follows: 30.0-55.0 parts of a fluorine-modified water-based self-crosslinking acrylate emulsion, 0.1-1.5 parts of a neutralizer, 0.5-1.0 part of a silane coupling agent, 0.1-0.2 parts of laurocapram, 0.6-1.0 part of chlorinated paraffin, 4.0-8.0 parts of inorganic sol, 1.5-3.5 parts of metal salt, 0.1-0.3 parts of glycerin, 0.1-0.2 parts of sodium carboxymethylcellulose, 0.1-0.2 parts of polydimethylsiloxane, 1.5-5.5 parts of a cosolvent, 1.0-2.5 parts of aluminium dihydrogen phosphate and 40-50 parts of water; the curing temperature is as low as 40-60 DEG C, and energy consumption is reduced. The fluorine-modified water-based self-crosslinking acrylate emulsion is adopted to enable a film to have weather-resistant, waterproof and self-cleaning performance and the like, the film has a self-repairing function when damaged, and the forming processability is greatly improved. Low VOC (volatile organic compounds) emission is realized, and the problem of chromium passivation pollution is solved.
