Abstract
The disclosure relates to a method for coating of a floor panel and a floor panel produced by the method. The disclosure relates to a method for producing a laminated product, for example a building panel, preferably a floor panel. The method comprises applying a paper on one side of a wood fiber based core, e.g. an HDF panel, creating a décor on the paper by a digital printing process, applying a resin, preferably a melamine formaldehyde resin, on the paper, heating the décor and the paper with the resin, preferably by using an IR lamp; and applying heat and pressure in order to cure the resin and thereby obtain a laminated product. The disclosure also relates to alternative methods for producing a laminated product, and such a laminated product.
Claims21
A method for producing a laminated building panel, wherein the method comprises:
- applying a paper on one side of a wood fiber based core,
- after applying the paper on the core creating a décor on the paper by a digital printing process while paper is on core,
- applying a resin in powder form on the paper;
- heating the décor and the paper with the resin;
- and
- applying heat and pressure in order to cure the resin and thereby obtain a laminated product.
A method for producing a laminated building panel, wherein the method comprises:
- applying a powder based sub layer comprising wood fibers and a thermosetting resin on a wood fiber based core,
- applying a raw paper on the powder based sub layer,
- applying a powder comprising a melamine formaldehyde resin and aluminum oxide on said raw paper to form a protective overlay on said raw paper;
- applying heat and pressure in order to impregnate the raw paper, to cure the resin and thereby obtain a laminated product.
A method for producing a laminated building panel, wherein the method comprises:
- applying a paper on one side of a wood fiber based core, the paper being unimpregnated when the paper is applied on the core;
- digitally printing a décor directly onto the paper using a digital printer while paper is on the core;
- applying a resin directly on the paper while the paper is on the core and the paper remains unimpregnated;
- heating the paper, the décor, and the resin while the paper, the décor, and the resin are on the core;
- and
- simultaneously applying heat and pressure to cure the resin and thereby obtain a laminated product, the simultaneously applying heat and pressure being after the heating of the paper, the décor and the resin.
