Abstract

The invention discloses a waterborne low-energy cold light source-cured metal coating and a preparation method thereof. The waterborne low-energy cold light source-cured metal coating is prepared fromthe following raw materials by weight: 42% of water-soluble difunctional aliphatic polyurethane acrylate, 10% of water-soluble polyester acrylate resin, 10% of water-soluble acrylate resin, 0.3% of awaterborne dispersant, 13% of alcohol, 0.3% of waterborne fumed silica, 3% of matting powder, 2% of waterborne polytetrafluoroethylene, 4.5% of a waterborne photoinitiator, 0.3% of a waterborne leveling agent, 0.3% of a waterborne defoamer, 0.3% of a waterborne wetting agent, 13.9% of deionized water and 0.1% of bactericide, with the balance being water. The low-energy UV LED (light emitting diode) cured coating of the invention is low in energy consumption, does not produce ozone, contains no mercury, has no pollution to environment and no harm to human beings, and is fast in curing speed and high in curing efficiency; and since water is used as a diluent, the coating is environmentally friendlier.
