The invention discloses water-based UV aluminum
powder paint and a preparation method thereof. The water-based UV aluminum
powder paint contains the following components by weight percent: 50%-60% of a 4-5 functional waterborne
polyurethane acrylate dispersion body, 5%-10% of
pentaerythritol triacrylate, 4%-5% of water-based aluminum-
silver paste, 1%-5% of a
photoinitiator, 1%-5% of a water-based EVA
wax emulsion, 1%-5% of a water-based
polyamide wax, 1%-2% of a
wetting agent, 1%-2% of a dispersing agent, 5%-10% of an organic cosolvent, 10%-15% of pure water, 1%-2% of a rheological agent and 0.3%-0.5% of an
ammonia neutralizer. According to the water-based UV aluminum
powder paint and the preparation method, the disadvantages and deficiencies in the prior art are overcome, the VOC content of the UV aluminum powder paint is 100g / L-150g / L and is decreased by 70%-80% compared with that of the traditional
solvent type aluminum powder paint; after a
coating film is irradiated by virtue of
ultraviolet light (for 10-20 seconds), a film can be formed through
drying; after the
coating film is dried, the directional alignment property of aluminum powder is good, the
coating film has excellent physical and chemical properties, the production efficiency is high, the
energy conservation and the emission reduction are realized, and the aluminum powder paint can pass relevant detection standards of cosmetic coatings.
