[0123] LVT-Reference 1

[0124] Will be 9g / m 2 A coating in the form of a UV-curing lacquer (curing lacquer) is applied to a luxury vinyl floor (LVT) containing a core, a decorative layer and a protective layer. The coating is applied to the protective layer. The UV-curing paint cures at a speed of 10m / min. Use two mercury lamps each with 120W light effect.

[0125] The resulting product was placed under a UV lamp and tested for hydrophilicity. After 1 week in the UV lamp, the product showed hydrophobic behavior.

[0126] LVT-Reference 2

[0127] Will be 9g / m 2 A coating in the form of a UV-curable lacquer is applied to a luxury vinyl floor (LVT) containing a core, a decorative layer and a protective layer. The coating is applied to the protective layer. 5g of a photocatalytic coating fluid containing 1.5% by weight of nanofluid and 0.5% by weight of BYK-348 was applied to the UV coating, wherein the nanofluid contained photocatalytic nanoparticles and was of the type described i...

Abstract

The present disclosure relates to a method for coating a building panel (1, 1'), comprising applying a first coating fluid comprising an organic binder on a surface (11) of the building panel (1,1') to obtain at least one coating layer (13), and applying barrier components and photocatalytic particles, preferably TiO2, on said at least one coating layer (13). The invention also relates to such a building panel (1, 1').

Description

Technical field [0001] The present invention generally relates to the field of building panels, such as floor panels, wall panels and furniture components, and methods for coating building panels with photocatalytic coatings. Background technique [0002] When it comes to floor panels and wall panels, the visual appearance is very important. In addition, due to the new regulations, it is important to introduce properties that can reduce indoor volatile organic compound (VOC) levels. [0003] It is well known that building materials can obtain photocatalytic properties. US 6,409,821 describes how to use micron TiO 2 TiO 2 Applied to external cement construction materials. [0004] Furthermore, it is shown in WO 2009 / 062516 that nanoparticles can be applied to the surface of laminates or veneer and introduce photocatalytic properties to internal surfaces such as floor panels. [0005] US 2010 / 0058954 describes a carbon-modified titanium dioxide film disposed on a substrate such as gla...
