Preparation method and application of yellowing-resistant water-based UV ultra-matte open top-coat for dyeing technical veneers

The invention discloses a preparation method and application of an anti-yellowing water-based UV ultra-matte open top-coat for dyeing technical veneers, relates to the technical field of coatings, and aims to solve the problems that a paint film is poor in transparency, easy to turn white, poor in color fastness, serious in later fading and easy to yellow when water-based UV is used for construction on the dyed veneers at present. The yellowing-resistant water-based UV ultra-matte open top-coat is prepared from the following components in parts by weight: 65 to 80 parts of water-based emulsion, 1 to 3 parts of a photoinitiator, 0.5 to 1 part of a wetting leveling agent, 0.2 to 0.5 part of a defoaming agent, 0 to 5 parts of filler, 1 to 3 parts of a light stabilizer, 0.3 to 0.8 part of a multifunctional additive, 0.5 to 1.5 parts of a thickening agent and 15 to 25 parts of deionized water. The anti-yellowing water-based UV ultra-matte open top-coat paint prepared by the invention takes water as a solvent, a sm
