Definitions

  • the invention relates to a floor panel, in particular a laminate floor panel, with resin-impregnated, in particular paper-thin layers, which are pressed with a carrier plate.
  • the invention relates to a method for producing the floor panel.
  • the flooring known from the prior art is a decorative layer system generally made of papers impregnated with thermosetting resins and pressed with a backing plate, the optical decorative effect of which is provided by a decorative paper of the impregnated papers is achieved.
  • a typical structure of a floor of the aforementioned type is designed such that the top layer is a so-called overlay paper impregnated with melamine resins, which contains abrasive particles embedded in the resin such as corundum particles to increase the abrasion resistance of the floor.
  • a printed paper impregnated with melamine and / or urea resins which forms the decorative layer of the finished floor.
  • the floor closes with a counter-impregnated with melamine and / or urea resins Reifenzugpapier whose function is to prevent warping and bowls of the finished floor panels by a symmetrical construction of the floor.
  • the mentioned resinated paper layers are connected plate by means of short cycle presses serving as a carrier layer wood material.
  • the wood-based panel may be, for example, a chipboard or a hardboard (HDF).
  • the uppermost layer, i. H. the overlay layer is completely transparent and the final product is a deco- ration print image that clearly shows the desired visual effect.
  • An alternative product structure is that the overlay layer is saved for reasons of cost, and instead the decorative paper is provided on the upper side with a resin layer which is provided with corundum particles to protect the printed layer.
  • the antistatic laminate flooring currently available uses different approaches to ensure that persons under 2 KV are charged according to DIN EN 1815.
  • a discharge of the charge allows.
  • the substances used to dissipate the static charge can either have a permanent conductivity (graphites, carbon blacks, carbon fibers, metal fibers, metal oxides) or unfold their action due to the absorption of moisture that promotes charge dissipation (salts, ammonium compounds).
  • the first-mentioned substances have the disadvantage that they can be used only below the printing layer, ie the printed paper due to lack of transparency or their strong inherent color. Although the latter compounds can be pressed into the resin transparently within certain limits, they adversely affect the strength of use and the water resistance of the cured resin surface and are more strongly climate-dependent in their effect, since the conductivity depends on the moisture content of the antistatic layer. Also in the relevant patent literature antistatic floors have been discussed.
  • the present invention therefore has the object, a floor panel in such a way that a conductive and transparent layer in order to achieve an antistatic effect Any position of the layer sequence of the soil can be positioned.
  • the antistatic effect should not be associated with a reduction in the water resistance of the surface.
  • At least one layer is provided with conductive and transparent pigments.
  • an impregnated printed decor paper may be provided with a resin layer containing sufficiently high concentration of the conductive and transparent pigment.
  • the conductive and transparent pigments may also be contained in the resin-impregnated layer by admixture. Homogeneous and uniform distribution of the pigments in the resin coating or in the resin-impregnated layer produces contacts between the pigments and thus electrical conduction paths which cause the static charge to dissipate.
  • the conductive layer may also be above the printed paper, i. H. lie above the decorative printing layer. Because of the transparency, namely, the optical effect of the printed paper is not affected.
  • the core idea of the invention is thus to provide a floor, in particular a laminate floor, with a layer of conductive and transparent pigments in order to achieve an antistatic effect in this way and at the same time to preserve the optical effect of the decorative printing layer.
  • Further advantages of the invention are that due to the conductivity of the pigments, for example of mica pigments, the antistatic effect is not moisture-dependent. Thus, there is no antistatic effect that works on the basis of hygroscopic properties and therefore strongly depends on the room humidity.
  • an advantageous embodiment of the invention provides that the floor has the structure of a Laminatfußbodens.
  • an overlay paper is provided, which is located on a printed paper serving as a decorative layer, wherein above the support plate, the printed paper and below the support plate is a Schmidtkompapier.
  • a practicable variant of the invention therefore provides that a printed paper serving as a decorative layer is located above the carrier plate and a traction paper below the carrier plate, the printed paper being provided with a resin coating on the side facing away from the carrier plate.
  • the resin layer is expediently provided with corundum particles.
  • the support plate is in the form of a wood-based panel, wherein a wood-fiber board (HDF) or a chipboard can serve as the wood-based panel.
  • a wood-fiber board (HDF) or a chipboard can serve as the wood-based panel.
  • a practicable variant of the invention provides that the layers are impregnated with melamine and / or urea resins. This is advantageous because the papers used in the invention absorb these curable liquids well.
  • a further advantageous embodiment of the invention is that the transparent mica pigments carry a conductive coating. In addition to the advantage of transparency, the conductivity of the mica pigments, as already mentioned, is not moisture-dependent. In addition, the mica pigments do not reduce the water resistance of the resin surface and provide high long term stability because the active conductive components can not migrate.
  • Pigment application weights of 0.1-15 g / m 2 in particular application weights of 1-5 g / m 2 have proven to be antistatic and very well transparent.
  • the layers with the support plate are pressure and / or heat-pressed.
  • the floor according to the invention is provided to provide the printed paper, which forms the decorative layer of the floor, with a resin coating containing the mica pigments. This creates the possibility of positioning a conductive layer even above the decorative layer, since the mica pigments, in addition to the conductivity, also have the necessary transparency for the optical development of the decorative layer.
  • a method is suitable in which paper, resin-impregnated layers are pressed with a carrier plate, wherein prior to the compression of at least one layer conductive and transparent pigments are added.
  • the pigments are preferably mica pigments.
  • the papers referred to in conventional terminology as overlay paper, printed paper (decorative layer) and as backing paper are impregnated on both sides with melamine and / or urea resins.
