Abstract

The invention relates to a water-based UV paint, particularly a high-water-resistance quick-photocuring pearlescent water-based UV paint, and a preparation method and application method thereof. The paint is prepared from a water-based polyurethane acrylate resin, a water-based epoxy acrylic resin, a functional monomer, a photoinitiator, a leveling agent, an anti-settling agent, pearl powder and a solvent, wherein the functional monomer comprises at least one of dipentaerythritol hexaacrylate, pentaerythritol triacrylate and trimethylolpropane triacrylate. The number of the functional groups of the dipentaerythritol hexaacrylate, pentaerythritol triacrylate and trimethylolpropane triacrylate is 3 or above. The photocured paint film has the advantages of high crosslinking density, excellent hardness, excellent tensile strength and excellent mechanical properties. The water-based epoxy acrylic resin is introduced on the basis of the water-based polyurethane acrylic resin, thereby enhancing the water resistance of the paint film. By introducing the pearl powder and anti-settling agent, the paint film has gorgeous pearl effects.

Description

technical field [0001] The invention relates to a water-based UV paint, in particular to a pearlescent water-based UV paint with high water resistance and rapid photocuring. Background technique [0002] With the enhancement of human awareness of environmental protection, various countries have successively formulated environmental protection regulations on VOC (volatile organic compound) emissions, and the emission standards have become increasingly strict, aiming to encourage the promotion of new products that are green, environmentally friendly, energy-saving and emission-reducing. Therefore, in the field of paint coating, the development and application of safe and low-VOC water-based, powder and high-solids environment-friendly paints is imperative. Because water-based UV coatings have the characteristics of many technical approaches, wide application, safety, and relatively simple construction, they have developed rapidly in Europe, America and other developed countrie...
