Definitions

  • the invention relates to a method for producing a prefinished panel for floorings and coverings and a relevant production method and the relevant panel.
  • those panels have a wooden support substrate which is intended to fulfil the mechanical functions of the flooring and to which a relatively thin finishing layer is adhesively bonded, in comparison with the thickness of the support, for example, wood of a more highly valued substance than the support. Therefore, any finishing varnish is applied to that thin layer.
  • a prefinished panel comprises a substrate of a material based on cellulose/polyester and a decorative layer covered with one or more layers of transparent PVC plastisol.
  • the superficial layer of PVC plastisol comprises a series of coloured scales or glass scales so as to confer a specific aesthetic appearance and, to that end, is spread with a spatula on the layer below.
  • a resin of small thickness, comparable to that of the substrate of 0.15 mm.
  • the need for printing the decorative layer beforehand and subsequently applying it to the substrate is not very suitable in the case of high-quality printing, requiring particular attention during the application phase.
  • An object of the invention is to provide a prefinished panel which allows all the disadvantages set out with reference to the cited prior art to be overcome.
  • support substrate 2 which is preferably constructed from known material with the commercial name Dibond® produced by 3A Composites.
  • That material is formed by two sheets of aluminium which have a thickness equal to 0.012" (approximately 0.3 mm) and which are fixed to a polyethylene core.
  • the aluminium sheets therefore form two superficial layers 21 which define the outer faces of the substrate.
  • Dibond® there could be provision for the use of a substrate of other materials composed of aluminium, in which at least one outer face is composed of that material or an alloy thereof.
  • the method according to the present invention provides for a direct printing step on the outer layer of aluminium so as to form a superficial decorative layer 4.
  • the decorative layer is illustrated as a separate layer with respect to the substrate for greater descriptive clarity, the layer also being printed directly on the outer surface thereof.
  • That layer will be defined by an image printed on the face of the substrate 2 preferably by means of direct UV printing. That technology is known per se and is, for example, produced with digital printers of the type Durst Rho 800 or Daytona H700UV Flatbed Printer.
  • the superficial layer of aluminium is particularly suitable for being printed directly, allowing high definition and short drying times.
  • UV ink-jet printing technology also allows continuous printing on surfaces having large dimensions.
  • That capacity together with the structural characteristics of Dibond, allows the construction of prefinished panels having large dimensions even of 200 x 400 cm.
  • the method according to the present invention provides for the application of a transparent covering layer produced by pouring an aliphatic epoxy resin or aliphatic polyurethane resin having self-levelling properties.
  • Those resins also have the property of dissipating the solvents used during the solidifying step, which may occur at ambient temperature, making those materials completely suitable for forming coverings having surfaces which are intended for contact with food products.
  • the resin is poured on the printed surface by means of one or more nozzles and, owing to the self-levelling properties, once it has been poured it is capable of spreading to form a uniform and continuous layer above the decorative layer.
  • the resin becomes transparent and the decorative layer will be completely covered by the covering layer.
  • the covering layer 5 is applied to the second layer with a mean thickness between 1.2 mm and 3 mm and preferably with a mean thickness of approximately 1.5 mm.
  • the covering layer 5 therefore allows, on the one hand, the decorative layer to be covered and the panel to be provided with surface resistance, in particular to being walked on.
  • the thickness used depends on the type of intended purpose of the panel and the decoration underneath.
  • That production method together with the specific combination of materials used, is therefore particularly advantageous because it does not require any type of processing for spreading the covering layer.
  • a superficial layer of aluminium having a thickness greater than 0.1 mm allows the use of sufficiently thick layers of resin, providing overall a prefinished panel of high quality.
  • the covering layer 5 of resin may have form impressions, markings or the like, generally designated 6.
  • the panel 1 is intended to be positioned on a flooring, it is advantageous to provide another fourth protective layer 7 of scratch-resistant varnish, for example, an aqueous acrylic/polyurethane varnish.
  • Those varnishes are conventionally used as superficial finishes after positioning for floorings of wood of the parquet type.
  • the panel is provided on the four perimeter edges with connection profiles 3 with conjugate shapes for connection to adjacent panels in an interlocking manner. Suitable profiles in that sense are described, for example, in US 7,658,048 .
  • the panel 1 is constructed on the basis of the substrate 2 with subsequent positioning of the above-indicated layers.
  • the panel may be positioned in the dry state, without using adhesives or the like.
  • the method thereby solves the problem set out, affording a number of advantages including that of allowing a high level of personalization of the panels constructed, owing to the use of direct printing on the substrate.
  • the method is particularly well suited to being implemented in systems with linear advance, allowing optimum implementation at an industrial level.
  • the specific combination of materials further allows the construction of panels having large dimensions which are completely decorated and particularly resistant.
  • those panels may be readily produced to order and positioned, reducing the storage and site costs.
