Problems solved by technology

At present, after UV coating, many UV white coatings on the market will accelerate aging and yellowing due to the multiple irradiation and curing of ultraviolet rays. The data measured by the colorimeter shows that the L value is low, the b value is high, and the color hue is not enough. White, yellowish, affecting the color appearance and visual effect of furniture

Abstract

The invention provides a UV (ultraviolet) white coating system, composed of UV high-adhesion base varnish, UV ultra-white base coat and UV ultra-white top coat. The UV high-adhesion base varnish has afilm-forming base made with modified epoxy acrylate, difunctional aliphatic polyurethane, a pure acrylate, 1,6-hexanediol diacrylate, and hydroxyethyl methylacrylate; the UV ultra-white base coat hasa film-forming base made with modified epoxy acrylate, difunctional polyester acrylate, a pure acrylate, 1,6-hexanediol diacrylate, and dipropylene glycol diacrylate; the UV ultra-white top coat hasa film-forming base made with modified epoxy acrylate, difunctional aliphatic polyurethane, a pure acrylate, trimethylolpropane triacrylate, and dipropylene glycol diacrylate. A white coating layer ofgood adhesion, leveling property, high L value and low b value is formed by: performing multiple coating with the combination of UV base coat and UV top coat having different functions, and forming films respectively via UA.

Description

technical field [0001] The invention belongs to the technical field of UV coatings, and in particular relates to a UV white coating system, a preparation method and a coating process. Background technique [0002] Ultraviolet radiation curing technology is a brand-new green environmental protection technology, and the ultraviolet light curing coating produced by this technology is referred to as UV coating for short. At present, my country's development has entered a new era, people's needs for a better life are increasingly extensive, and higher requirements are put forward for material and cultural life. More and more cabinets, furniture, and wooden doors are using UV curing technology to protect and decorate panels with green and environmentally friendly coatings. White cabinets and white furniture are very popular among market consumers, so how to distinguish the color hue of white furniture? In the past, people mainly felt the difference in color with the naked eye, b...
