Definitions

  • This invention relates to floor panels.
  • the invention relates to floor panels with a substrate and a provided thereon top layer with a printed decor.
  • floor panels are widely known as such, for example, from WO 97/47834.
  • the floor panels disclosed there relate to, amongst others, floor panels with a substrate which substantially consists of a HDF board with a laminate layer which is directly pressed thereon and which comprises one or more paper sheets impregnated with melamine resin, amongst which preferably also a paper sheet with a print in, for example, a wood or stone motif, namely a so-called decor paper.
  • melamine surface of such laminate panel leads to the occurrence of ticking sounds when in use. From the state of the art, a plurality of solutions to this problem is known.
  • a material with a different hardening mechanism than PVC can be made of a material with a different hardening mechanism than PVC.
  • PVC hardens by cooling off
  • a material is chosen which hardens according to a different mechanism than cooling off.
  • this may relate to a thermally hardening material, such as a melamine-based resin, a UV-hardening lacquer layer, an electron beam-hardening lacquer layer, an excimer-hardening lacquer layer, a drying lacquer layer or the like.
  • said wear layer preferably relates to a lacquer layer, such as an acrylic-based layer or a urethane-based layer.
  • a lacquer layer is applied which can be hardened by radiation or can be hardened by drying of a solvent.
  • said sublayer is adhered directly to the substrate, without the intermediary of glue layers.
  • a PVC plastisol is used, which, in liquid or paste form, is provided on the surface of the substrate and is foamed there.
  • the sublayer is cooled off by means of a press element, for example, by means of one or more press rollers or press belts, such that the thickness thereof can be calibrated to a certain extent.
  • the aforementioned material sheet is a paper sheet, preferably an alpha- cellulose paper.
  • the paper sheet has a weight of 25 g/m 2 to 65 g/m 2 .
  • said material sheet is a paper sheet, preferably an alpha-cellulose paper sheet, which comprises embedded hard, for example, mineral, particles, such as aluminum oxide particles or corundum.
  • the respective paper sheet comprises 2 to 20 grams per square meter of such particles, and preferably with an average particle size between 20 and 200 micrometers.
  • the paper sheet has a weight, including embedded particles, of 25 g/m 2 to 65 g/m 2 . This may relate, for example, to a paper sheet in accordance with the US 5,820,937 already mentioned above.
  • a decorative panel having the characteristics of the present second aspect of the invention may also show the characteristics of the first aspect or the preferred embodiments thereof.
  • the aforementioned carrier is a paper or a foil
  • the method preferably further also comprises the step of providing said carrier on a plate-shaped or profiled substrate.
  • Such providing preferably is performed by gluing the respective carrier onto the substrate, for example, by means of a so-called encasing process, for example, of the type such as known from US 3,296,056 or US 4,198,455.
  • the method of the third aspect allows making the transparent lacquer layer thinner while still obtaining a wear resistance required, for example, for the application in floors.
  • the restricted thickness of the lacquer layer provides for a smooth application of the carrier on the substrate.
  • the obtained wear-resistance of the decorative panel or profile preferably reaches the wear class AC2 or higher, even up to AC5 and higher, as expressed according to EN 13329-Annex E.
  • the respective material sheet, prior to being provided in the lacquer also is provided with lacquer, for example, impregnated with lacquer.
  • this herein relates to the same lacquer as provided on the carrier.
  • the step of providing the lacquer on the carrier may be omitted.
  • said carrier, prior to said step of providing the lacquer in liquid condition is printed, preferably by means of a digital printing technique, for example, by means of UV-hardening or water-based inks. Solvent-based inks, latex inks or oil-based inks are not excluded.
  • the print is formed on the respective carrier, possibly with the intermediary of primer layers, such as preparatory layers.
  • the carrier relates to a plate-shaped or profiled substrate
  • this substrate preferably is at least prepared with one or more layers of a uniform color and/or with a paper sheet.
  • the carrier comprises a paper or a foil
  • the carrier preferably is at least prepared with an inkjet receiver coating.
  • the aforementioned material sheet preferably is a paper sheet, and still better a paper sheet comprising embedded hard particles.
  • Figure 7 in a view similar to that of figure 3, represents another embodiment of the second aspect of the invention.
  • Figure 2 further clearly shows that the floor panel 1 of the example is of the type having a substrate 13 and a top layer 14 provided thereon.
  • the top layer 14 comprises at least a printed decor 15 and a transparent wear layer 16 situated there above.
  • the floor panel 1 between the aforementioned printed decor 15 and the aforementioned substrate 13, comprises a foamed sublayer 17, preferably of PVC or another thermoplastic material, and that said wear layer 16 is free from PVC and is not foamed.
  • the thickness T1 of the wear layer 16 is less than the thickness T2 of the sublayer 17.
  • this relates to a sublayer 17 which comprises foamed PVC.
  • the substrate 13 comprises a HDF board (High Density Fiberboard) having an average density of more than 750 kilograms per cubic meter.
  • a board material can be used, for example, HDF or MDF, having a thickness T3 of 3 millimeters or more.
  • the thickness T3 of the substrate 13 is between 4.5 and 7 millimeters.
  • an optional backing layer 22 is applied on the lower side of the substrate 13, in the case of the example of figure 2 also an optional backing layer 22 is applied.
  • Such backing layer preferably consists of a material similar or equal to that of the wear layer 16 and/or the sublayer 17.
  • the inventor has found that a good printing quality can be obtained regardless the presence of a foamed surface.
  • the sublayer 17 comprises a glass fleece or glass fabric 23.
  • the glass fleece or glass fabric 23 is situated in the upper quarter 24 of said sublayer 17.
  • Figure 5 represents another variant, wherein the wear layer 16, at the surface 27 thereof, is provided with a structure or relief of embossments 28.
  • the embossment 29 forms an example of an embossment for imitating wood pores.
  • the embossments 30 form a bordering of the decor 15 in the form of chamfers at the edges 19 of the floor panel 1.
  • the embossments 30 form an example of structural parts which continue up into the sublayer 17, wherein the printed decor 15 is also structured at the location of these embossments 30.
  • even the reinforcement layer 23 follows the contour of the embossments 30.
  • FIG 9 clearly shows that the covering 40 comprises a carrier 41 in the form of a paper or foil.
  • the carrier 41 is provided with a printed decor 15 and is finished with a wear layer 16.
  • the wear layer 16 shows a similar composition as the wear layers of figures 6 and 7.
  • the covering 49 is provided as a whole on the substrate 13A by means of a glue layer 42, for example, by means of a encasing process.
  • the composition of the transparent wear layer 16 is represented schematically only and that the cellulose fibers of the material sheet 31 in practice can be spread over a larger portion of the thickness T1 of the lacquer layer. In practice, the respective material sheet 31 can adjoin against the printed decor 15.
  • the wear layer 16 at its surface comprises a zone formed by a portion of lacquer which is free from cellulose fibers
  • the present invention is in no way restricted to the herein above-described embodiments, on the contrary may such floor panels, decorative panels, decorative profiles and methods for manufacturing them be realized without leaving the scope of the present invention.
