Floor panel for forming a floor covering and method for manufacturing such floor panels
A method for manufacturing a floor panel having a substrate and a top layer. The top layer may have a decorative layer that includes a digital print and a transparent or translucent wear layer. The method may involve providing the substrate with the digital print by jetting one or more inks from a set of inks using a digital inkjet printer. The ink may include a binding agent and/or a primer or adhesion layer may be provided between the digital print and the transparent or translucent wear layer. The digital print may be performed directly on the substrate. The transparent or translucent wear layer may be laminated on top of the printed substrate.
1. A method for manufacturing a floor panel having a substrate and a top layer, the top layer having a decorative layer that includes a digital print and a transparent or translucent wear layer, the method comprising:
providing the substrate with the digital print by jetting one or more inks from a set of inks using a digital inkjet printer;
wherein the ink includes a binding agent and/or wherein a primer or adhesion layer is provided between the digital print and the transparent or translucent wear layer;
wherein the digital print is performed directly on the substrate;
providing the transparent or translucent wear layer; and
laminating the transparent or translucent wear layer on top of the printed substrate.
2. The method of claim 1 , wherein the digital print is performed directly with the intermediary of a preparative layer.
3. The method of claim 1 , wherein the substrate substantially consists of synthetic material and/or filler material.
4. The method of claim 1 , wherein the substrate is a PVC-containing substrate.
5. The method of claim 1 , wherein the substrate is composed of a thermoplastic material.
6. The method of claim 1 , wherein the transparent or translucent wear layer is made of a thermoplastic material.
7. The method of claim 6 , wherein the thermoplastic material is PVC.
8. The method of claim 6 , wherein the transparent or translucent wear layer has a thickness of 150 micrometers or more.
9. The method of claim 1 , wherein the primer or adhesion layer comprises a binder or binding agent.
10. The method of claim 9 , wherein said additional binder or binding agent of the primer or adhesion layer is the same as the binding agent contained in the ink.
11. The method of claim 1 , wherein the binding agent comprises VC-VAC copolymer or polymer latexes, either acrylates or urethane components.
12. The method of claim 1 , wherein the binding agent is present in an amount below 20 percent by weight of the ink.
13. The method of claim 12 , wherein the binding agent is present in an amount of at least 2 percent by weight of the ink.
14. The method of claim 1 , wherein the set of inks comprises solvent based inks, UV based inks, or water-based inks.
15. The method of claim 1 , wherein the inks in the set of inks comprise pigments.
16. The method of claim 1 , wherein the set of inks is CMYK.
17. The method of claim 1 , wherein the primer or adhesion layer is applied using a roller or a printhead.
18. The method of claim 1 , comprising:
providing a lacquer layer as a liquid layer on the transparent or translucent wear layer and/or the decorative layer; and
subsequently solidifying the lacquer layer.
