Definitions

  • the present invention relates to the technical sector of processes for varnishing the surfaces of floor and wall coverings intended to be in contact with the user.
  • the deposition of a varnish in a thin layer tends to degrade the appearance of the graining on the surface of the coating and therefore its realism.
  • This aspect is particularly troublesome in the case of a coating process for coatings obtained from synthetic materials such as polyvinyl chloride (PVC).
  • PVC polyvinyl chloride
  • the exploitation rate of a grain corresponding to the depth of the graining tool relative to the depth of the grain on the coating, is generally reduced after the varnishing step.
  • the varnish deposited naturally tends to fill in the hollow areas and to become thinner on the peaks of the grain, which “smoothes” the surface of the coating. Varnish defects such as cordage can also appear on very accentuated grains, in particular with a depth greater than 100 ⁇ m.
  • One of the known means for remedying this problem consists in depositing a varnish in droplets, in particular using techniques similar to those used in ink jet printing.
  • the ink is replaced by the varnish, the latter being sprayed in droplets of the order of 3 to 20 picoliters by multiple nozzles carried by a print head.
  • the droplets are projected onto the substrate to be covered in a numerically defined pattern, the pattern possibly being flat, in the plane of the substrate extending along two axes (X, Y), or three-dimensional so as to obtain a relief along three axes (X Y Z).
  • these techniques do not make it possible to obtain a satisfactory matt finish.
  • the gloss of a varnish deposited in a droplet by an inkjet printing process and which would not have undergone a subsequent treatment is generally greater than 90 gloss units (BU).
  • the object of the invention is to propose a method of varnishing a floor or wall covering making it possible to obtain a more matte varnish while retaining good resistance to fouling and satisfactory roughness, in particular on grains of 50 to 1000 ⁇ m deep.
  • One of the aims of the invention is in particular to propose a varnishing process making it possible to obtain a layer of matt or even very matt varnish, in particular a varnish having a gloss of 1 to 13 gloss units (BU), preferably of 1 at 7 BU, more preferably from 1 to 3 BU measured according to ISO 2813 at 60 °.
  • BU gloss units
  • Another object of the invention is to propose a varnishing process making it possible to obtain a varnish with a "soft" feel, in particular a layer of varnish whose surface has a very fine tension, which can be characterized by a distance between two grooves of l '' from 3 to 6 ⁇ m.
  • Another object of the invention is to propose a varnishing process making it possible to obtain a layer of varnish having a relief structure.
  • Another object of the invention is to propose a varnishing process making it possible to obtain a layer of varnish which may have large variations in thickness, in particular a layer of varnish whose thickness varies between 6 ⁇ m and 1 mm or even between 6 and 200 ⁇ m .
  • Another object of the invention is to propose a varnishing process making it possible to obtain a barrier layer against volatile organic compounds.
  • the method according to the invention makes it possible to obtain a layer of varnish having a low gloss of between 1 to 13 gloss units (BU), preferably from 1 to 7 BU or even between 1 and 3 BU.

  • DEL Diode Electro Luminescente
  • tensioning is meant crosslinking of the surface obtained by exposure to excimer monochromatic radiation.
  • pre-crosslinking means a partial crosslinking of the varnish in its thickness, that is to say that part of the deposited varnish remains wet.
  • the method according to the invention makes it possible to obtain a micro structured surface with a very fine tension characterized by a distance between two grooves of the order of 3 to 6 ⁇ m. This fine tension makes it possible to obtain a soft touch effect.
  • LEDs can be used in the method according to the invention.
  • the LED (s) used have an emission spectrum between 365 and 420 nm, it is however preferable to use LEDs having a single emission peak, for example an emission peak at 395 nm .
  • Exposure to UV radiation from an LED lamp upstream of a tensing step by exposure to excimer radiation makes it possible to level the tension of the varnish and to stretch it, even on very pronounced grains.
  • UV lamps not using LEDs, which can be used according to the invention are in particular lamps of the mercury vapor type, but also blades with so-called doped emitters (type Iron, Lead, Gallium, Gallium-Indium) . These lamps generally emit according to a spectrum extending between 200 nm and 400 nm.
  • Excimer type lamps are designed to emit monochromatic radiation from one or more sources or micro sources in order to address radiation on materials allowing, among other things, the crosslinking of a liquid film, the energetic activation of the surface. or the destruction of microorganisms or bacteria. Exposure to monochromatic radiation of the excimer type under an inert atmosphere can for example be carried out in the presence of nitrogen (N 2 ).

  • the varnish droplet deposition step is advantageously carried out by means of an ink jet print head.
  • the use of LED lamp also has the advantage of being transportable on a trolley alongside a print head of the inkjet printer.
  • the pre-crosslinking of the varnish droplets can therefore take place directly after their deposition by the ink jet heads. This makes it possible to perfectly preserve the deposited relief and to obtain a structured varnish.
  • the ultraviolet radiation under LED lamp has a spectrum between 365 and 420 nm.
  • the advantage of an LED lamp is that it makes it possible to obtain an emission spectrum more centered around a single emission peak than a conventional UV lamp, for example a UV mercury vapor lamp.

  • Typical LED ultraviolet lamps have an emission peak at 365 nm or 385 nm or 395 nm or 405 nm.
  • the choice of a photo-initiator activating only in the area of the emission spectrum of the LED lamp and not in the area of the emission spectrum of the UV lamp is therefore possible.

  • This makes it possible to obtain good pre-crosslinking during the step of exposure under ultraviolet radiation of the LED lamp and crosslinking at the core, that is to say throughout the thickness, under radiation from the UV lamp. keeping a simple formulation varnish.
  • the composition of the varnish comprises a first photo-initiator having a single absorption peak between 365 nm and 420 nm and a second photo-initiator having a single absorption peak between 250 nm and 300 nm.

  • the second photo-initiator is for example chosen with an absorption peak between 250 nm and 300 nm so as to remain insensitive to ultraviolet LED radiation and act only under radiation from the UV lamp during the last crosslinking step.
  • the first photo-initiator sensitive to the radiation of the LED lamp is generally incorporated at a concentration minority so as to carry out a simple pre-crosslinking, namely a partial crosslinking of the varnish in its thickness, leaving the surface tension possible under excimer monochromatic radiation.
