Abstract
Official abstract text for this publication.
A method to produce a building panel, including providing a core, applying a first paper layer on a first surface of the core, wherein the first paper layer includes a resin impregnated paper, applying refined lignocellulosic fibres on the first paper layer, applying a wood veneer layer above the refined lignocellulosic fibres, applying pressure to the core, the first paper layer, the refined lignocellulosic fibres, and the wood veneer layer to form a building panel. Also, to such building panel.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method to produce a building panel, comprising providing a core, applying a first paper layer on a first surface of the core, wherein the first paper layer comprises a resin impregnated paper, applying refined lignocellulosic fibres on the first paper layer, applying a wood veneer layer above the refined lignocellulosic fibres, applying pressure to the core, the first paper layer, the refined lignocellulosic fibres, and the wood veneer layer to form a building panel. 2. The method according to claim 1 , further comprising applying a second paper layer on the refined lignocellulosic fibres prior to applying the wood veneer layer and prior to applying the pressure. 3. The method according to claim 2 , wherein the second paper layer comprises a resin impregnated paper. 4. The method according to claim 2 , wherein the first paper layer and/or the second paper layer comprises a resin impregnated decorative paper. 5. The method according to claim 2 , wherein the first paper layer and/or the second paper layer comprises a resin impregnated overlay paper. 6. The method according to claim 1 , wherein the refined lignocellulosic fibres are resinated refined lignocellulosic fibres. 7. The method according to claim 1 , wherein refined lignocellulosic fibres are originating from a refining step in a MDF or HDF manufacturing process. 8. The method according to claim 1 , wherein the refined lignocellulosic fibres are applied as a powder. 9. The method according to claim 1 , wherein the core is formed prior to producing the building panel. 10. The method according to claim 1 , wherein an open structure in the wood veneer layer is at least partly filled by the refined lignocellulosic fibres after pressing. 11. The method according to claim 1 , wherein the refined lignocellulosic fibres are applied in an amount of 25-75 g/m 2 . 12. The method according to claim 1 , further comprising applying moisture to the first paper layer prior to applying the refined lignocellulosic fibres.
