Definitions

  • the present invention deals with a method for manufacturing a floor plank planks with a substrate, notably panels and boards, in particular wood based or thermoplastic based substrates on which a decor is formed by digital printing.
  • the invention also deals with a floor plank with a wood based substrate, obtainable using such a method.
  • Digital printing refers to methods of printing from a digital based image directly to the substrate. It usually refers to professional printing where small run jobs from desktop publishing and other digital sources are printed using large format and/or high volume laser or inkjet printers. Digital printing has a higher cost per printed object than traditional offset printing methods but this price is usually offset by the cost saving achieved by avoiding all the technical steps in between needed to make printing plates.
  • the decor may be printed on a separate support of paper or fleece which is applied onto the substrate.
  • a basic layer may be applied in order to ensure sufficient adherence of the applied inks, such basic layers may affect the printing quality.
  • a porous layer may absorb the ink leading to insufficient covering while a non-porous basic layer may lead to their coalescence and affect color quality.
  • the use of a separate support for printing however makes the process more costly and complex.
  • the substrate comprises a core layer made preferably from wood or thermoplastic material and an upper layer which is made of wood or derived from wood.
  • an upper layer thickness is relatively small and lies for example between 0.5 and 2.5 mm, it is usually referred to as “veneer”, and when the thickness is larger, for example between 2.5 and 4 mm it is usually referred to as ‘wooden lamellas’.
  • This upper layer is selected for having a nice aspect, devoid of any visible imperfections.
  • a single piece of veneer or wooden lamella covers the core layer of the plank.
  • the dimensions of the veneer are those of the plank, typically 2 m x 18-22 cm with a thickness of 0.5-2.5 mm (veneer) or 2.5-4.0 mm .
  • planks are rather expensive.
  • several pieces of veneer or wooden lamellas are used for covering the core layer.
  • each single piece has a smaller surface than the plank.
  • these smaller pieces cost less than the large ones, so that production costs are decreased.
  • the visual aspect of the plank is less qualitative, since the junctions between the pieces of veneer or wooden lamellas tend to remain visible, which gives the user an impression of lower quality.
  • a technique consisting in applying a fist layer containing a hardener and a second layer containing a filler on the pieces of veneer or the wooden lamellas has been used for efficiently hiding the junctions and obtaining planks with a smooth surface.
  • the obtained planks still lack realism compared with real wood.
  • Embossing and brushing are techniques known for providing surfaces with reliefs. However, they are also known, when applied on several adjacent pieces of veneer or wooden lamellas, for making the junctions more visible.
  • An aim of the invention is to provide a floor plank at a competitive cost and having an improved wooden aspect to the user.
  • the invention proposes a method for the manufacture of a floor plank, comprising at least the following successive steps:
  • a substrate comprising a core layer and a wood based upper layer formed with several pieces of veneer or wooden lamellas paving the core layer;
  • the method may comprise one or several of the following features, taken in isolation or any technically feasible combination:
  • the core layer comprises a material chosen from the group consisting of HDF, MDF, soft wood ribs, cardboards, a thermoplastic materials, and composite materials;
  • the hardener comprises an isocyanate
  • the hardener comprises a mix of hexane, 1 ,6-diisocyanato-homopolymer and hexamethylene-di-isocyanate;
  • the step of digitally printing includes a multipass digital printing
  • the upper layer has a thickness comprised between 0.5 and 4 mm;
  • the coating has a specific weight comprised between 10 and 50 g/m 2 ;
  • the coating has a thickness comprised between 5 and 10 pm;
  • the step of digitally printing includes a multipass digital printing
  • the step of digitally printing is carried out using UV ink or water-based ink.
  • the invention also relates to a floor plank successively comprising:
  • a substrate comprising a core layer, and a wood based upper layer formed with several pieces of veneer paving the core layer, the upper layer defining an upper surface being optionally sanded and being embossed, brushed, or embossed and brushed;
  • a coating located on the upper surface of the upper layer and containing a hardener, the coating defining an upper surface optionally sanded
  • the floor plank 1 has a thickness E along a direction N perpendicular to the floor plank.
  • the floor plank 1 in view along the direction N, may have any shape allowing paving a floor (not represented): rectangular, square, triangular, hexagonal... etc.
  • the floor plank 1 is intended to be applied on a floor adjacent to other planks (not represented) having the same shape or composition, or different ones.
  • the floor plank 1 includes locking tabs (knows in themselves and not represented) enabling to connect it to adjacent planks.
  • the floor plank 1 comprises a substrate 2, a coating 5, optionally a primer layer 7 located on the coated substrate, a decor 9 digitally printed on the primer layer, and a top coat 11 located on the decor.

  • the core layer 3 is obtained from panels or boards, in particular wood based boards, for example of the type used to form engineered wood as described in WO 2018/077636.
  • the upper layer 4 is for example formed by several pieces of veneer or wooden lamellas paving the core layer 2, of which two pieces 4A, 4B are represented on the Figure.
  • the floor plank 1 may have more than two pieces of veneer or wooden lamellas.
  • the upper layer 4 is for example made of wood, or derived from wood.
