Water-based one-coating baking-free ultraviolet-curing silver coating and preparation method thereof

The invention provides a water-based one-coating baking-free ultraviolet-curing silver coating and a preparation method thereof, belonging to the technical field of ultraviolet curing. Raw materials of the coating comprise water-based UV resin, a water-based wetting agent, a photoinitiator, a pH regulator, a thickening agent, a thixotropic agent, water-based silver powder, a water-based dispersingagent, a water-based coalescing agent and deionized water. The preparation method comprises the following specific steps: uniformly mixing the deionized water with the water-based dispersing agent, adding the water-based silver powder, and carrying out stirring to obtain water-based silver paste; mixing the deionized water and the thixotropic agent and carrying out stirring to obtain pre-preparedthixotropic agent slurry; uniformly stirring the water-based UV resin, the water-based wetting agent, the photoinitiator, the deionized water, the water-based dispersing agent and the water-based coalescing agent, and adjusti
