Preparation and Application of LEDUV-C Curable Waterborne Wood Coating Resin

Abstract

This invention discloses a preparation method and application of LEDUV-curable water-based wood coatings resin, belonging to the field of water-based coating technology. The process comprises the following steps: First, add the improved UV-curable fluorinated water-based polyurethane emulsion to a stainless steel dispersion tank. Under low-speed dispersion, incorporate the specified proportions of polyurethane thickener, preservative, dispersant, defoamer, wetting agent, nano additive, and light-blocking agent. After 25 minutes of high-speed dispersion, switch to low-speed dispersion. Then add the specified proportions of water-based wax emulsion, defoamer, leveling agent, silicone surfactant, and a modified 35% photoinitiator diacetylphosphine oxide solution. After another 25 minutes of high-speed dispersion, the LEDUV-curable water-based wood coatings resin is prepared. This invention significantly enhances the coatings hydrophobicity, water resistance, and pigment wetting performance while demonstrating excellent hardness, tensile strength, and yellowing resistance. Particularly suitable for wood furniture spray application, it achieves superior film transparency, surface smoothness, and comprehensive performance.
