Method of forming a decorative wear resistant layer
A method to form a digital print on a substrate including a polymer material by bonding particles in powder form to the surface of the substrate. The method may include: providing a substrate including a thermoplastic material and a transparent layer including a thermoplastic material, providing a continuous print layer including particles on the substrate or on the transparent layer, printing a digital image including color pigments on the print layer, and bonding the print layer with the color pigments to the transparent layer and to the substrate with heat and pressure such that the digital image is located between the transparent layer and the substrate.
1. A method of forming a decorative wear resistant layer, the method comprising:
providing a substrate comprising a thermoplastic material and a transparent layer comprising a thermoplastic material, the transparent layer being a thermoplastic foil,
providing a continuous print layer comprising at least one of mineral particles, fibers, or thermoplastic powder on the substrate or on the transparent layer,
printing a digital image comprising colour pigments on the at least one of the mineral particles, fibers, or thermoplastic powder of the print layer, and
bonding the print layer with the colour pigments to the transparent layer and to the substrate with heat and pressure such that the digital image is located between the transparent layer and the substrate.
2. The method as claimed in claim 1 , wherein the substrate is a thermoplastic foil.
3. The method as claimed in claim 1 , wherein the substrate is a core.
4. The method as claimed in claim 1 , wherein the print layer prior to printing is bonded to the substrate or the transparent layer with a binder.
5. The method as claimed in claim 1 , wherein the print layer prior to printing is bonded to the substrate or the transparent layer.
6. The method as claimed in claim 1 , wherein the print layer comprises the fibres.
7. The method as claimed in claim 1 , wherein the print layer comprises the thermoplastic powder.
8. The method as claimed claim 1 , wherein the print is made with water based ink.
9. The method as claimed in claim 1 , wherein the digital print is made with a liquid binder that bonds a powder comprising pigments.
10. The method as claimed in claim 1 , wherein the substrate is a part of a building panel.
11. The method as claimed in claim 1 , wherein the substrate is a part of a LVT floor panel.
12. The method according to claim 1 , wherein
the substrate is a thermoplastic foil, and
the bonding with the heat and the pressure further comprises bonding the substrate to a core so that a building panel is formed of the core, the substrate, the transparent layer, and the digital print image located between the transparent layer and the substrate.
13. A method of forming a decorative wear resistant layer of a building panel, the method comprising:
providing a core,
providing a first thermoplastic foil and a second thermoplastic foil, the second thermoplastic foil being transparent,
applying particles or fibers on the first thermoplastic foil or on the second thermoplastic foil,
printing a digital image comprising colour pigments on the particles or the fibers, and
bonding the print layer with the colour pigments to the first thermoplastic foil and the second thermoplastic foil by applying heat and pressure such that the digital image is located between the first thermoplastic foil and the second thermoplastic foil, the bonding including simultaneously bonding the first thermoplastic foil to the core when the heat and the pressure are applied so that the building panel is formed.
14. A method of forming a decorative wear resistant layer, the method comprising:
providing a first thermoplastic foil,
providing a second thermoplastic foil, the second thermoplastic foil being transparent,
applying a liquid binder to a surface of one of the first thermoplastic foil and the second thermoplastic foil,
applying a continuous print layer comprising loose particles on the one of the first thermoplastic foil and the second thermoplastic foil which the liquid binder has been applied to,
printing a digital image comprising colour pigments on the loose particles of the continuous print layer after the applying of the continuous print layer on the one of the first thermoplastic foil and the second thermoplastic foil, and
bonding the print layer with the colour pigments to the first and second thermoplastic foils with heat and pressure such that the digital image is located between the first thermoplastic foil and the second thermoplastic foil.
