Definitions

  • the present invention relates to a laminate panel, in particular wall, ceiling, furniture or floor panel, and to a method for producing a laminate panel.
  • Laminate panels are relatively inexpensive and can be processed well. They are usually based on a carrier plate (carrier layer) made of MDF or HDF material.
  • Laminate panels need to be protected against the ingress of water.
  • this relates to the profile region of laminate panels, i.e. the contact surface of adjacent laminate panels.
  • These profile regions usually constitute a weak point for water resistance.
  • the profile regions are usually finely milled in order to produce a substantially dense profile, as a result of which ingress of water is substantially prevented. Furthermore, a sealing can be provided, as a result of which the carrier material of the carrier plate can be rendered hydrophobic. As a further consequence, the liquid is thus prevented from ingress into the profile.
  • the state of the art proposes lacquering the profile regions or providing lacquer-based sealing means.
  • the invention is therefore based on the object of improving the previously known state of the art.
  • a laminate panel of the type described at the beginning should be provided which has a high resistance to ingress of water and which is at the same time inexpensive.
  • a laminate panel according to the invention in particular wall, ceiling, furniture or floor panel, comprises: a carrier plate, wherein the carrier plate is a medium density wood fibre (MDF) or high density wood fibre (HDF) plate, comprising coupling elements on at least one side surface of the carrier plate for connecting to another correspondingly shaped laminate panel; wherein the surfaces of the coupling elements are at least partially provided with oil.
  • MDF medium density wood fibre
  • HDF high density wood fibre
  • the laminate panel according to the invention offers the advantage that the ingress of liquids, such as water, can be counteracted in an improved manner. Consequently, the laminate panel is better protected.
  • the oil makes it possible for the carrier plate to be rendered hydrophobic. This can also be understood as a sealing.
  • the coupling elements of laminate panels are usually the weak points with regard to the ingress of water. According to the invention, this weak point can be substantially eliminated.
  • the quality of the carrier plate and of the laminate panel can then be substantially improved.
  • the carrier plate swells substantially less. This increases the durability of the carrier plate and of the laminate panel and thus leads to saving in terms of costs.
  • the carrier plate (also referred to herein for the sake of brevity as a plate) can be a plate which is produced from a wood-based material, such as a medium density fibre plate or a high density fibre plate, a particle plate, an oriented strand board (OSB) or the like. However, it can also be produced from a plastic material, such as luxury vinyl tile (LVT), a rigid polymer core, PCV, or an expanded polymer core, as well as mixed constructions which are widely used in the flooring industry.
  • the fibre plates allow good recyclability.
  • the plate typically has a longitudinal extent (length) in a longitudinal direction and a width, substantially perpendicularly to the longitudinal direction.
  • the width of the plate is typically small compared to the length.
  • the at least one side surface of the plate is oriented substantially perpendicularly to the main surface of the plate.
  • the side surface of the plate extends along the longitudinal direction of the carrier plate.
  • the carrier plate comprises coupling elements.
  • an element for example a groove or a tongue, can already be understood as a plurality of coupling elements due to two mutually engaging surfaces.
  • an upper side constitutes a first coupling element
  • a lower side constitutes a second coupling element.
  • the coupling elements can also be understood as a connecting structure.
  • the coupling elements make it possible for the plate to be connected to another plate. This can be effected e.g. by (partial) form-fitting, for example by a tongue- and-groove connection.
  • the coupling elements make it possible for the side surface to be configured to be brought into engagement with a side surface of another plate.
  • the other correspondingly shaped laminate panel can have a substantially congruent (or else substantially precisely fitting) coupling element.
  • the other correspondingly shaped laminate panel could also have other shapes and/or surface properties.
  • the surfaces of the coupling elements are at least partially provided with oil.
  • This can be understood as the oil being at least partially applied to the surfaces of the coupling elements.
  • the oil for example, is arranged substantially at the surfaces of the coupling elements.
  • the oil may have penetrated at least partially (in one example completely), into the surfaces of the coupling elements.
  • the oil can furthermore be naturally colored or colored in a different manner and can then be applied.
  • the oil can also be applied in combination with a lacquer, for example a chamfer lacquer, in the form of a mixture of lacquer and oil.
  • the oil can furthermore be dissolved in a carrier medium, for example a solvent or water, and can be applied in this state.
  • the oil is preferably provided in an amount sufficient to achieve a water tightness of the laminate panel according to NALFA test of ISO 4760 of at least 3, preferably at least 2, most preferably at least 1.
  • the oil is thus advantageously provided or applied to the surfaces of the coupling elements in an amount such that the properties described herein are valid.
  • the NALFA test is a standardized test method of the North American Laminate Flooring Association (NALFA). In this test, it is measured how a laminate panel behaves when its surface is exposed to standing water for about 24 hours. Before and after this time, the surface is measured at different measurement positions and the visual and tactile changes of the plate are recorded and evaluated. In particular, the swelling of the laminate material at the measurement positions is determined. Usually, in order to determine the swelling, a measurement position in the middle of an area on the laminate, for example on a cross-head, is selected as a reference. Furthermore, 3 measurement positions a few centimeters next to one another are selected.
  • NALFA North American Laminate Flooring Association
  • a value of less than 3 can be assigned according to ISO 4760.
  • the visual and/or tactile evaluation usually takes place according to the school grade system.
  • the oil applied to the surfaces of the coupling elements is part of a mixture of lacquer and oil applied to the surfaces of the coupling elements.
  • the mixture of lacquer and oil combines the advantageous hydrophobizing properties of the oil with the advantageous properties of the lacquer.
  • the lacquer for example, allows easier application and/or coloring of the mixture.
  • the mixture thus offers an advantage over the use of pure oil.
  • the oil per se in turn constitutes an improved hydrophobizing of the carrier plate than the use of pure lacquer.
  • the lacquer of the mixture of lacquer and oil can provide sufficient elasticity to compensate for deformation of the plate. It can also be that the lacquer of the mixture of lacquer and oil is based on a harder, i.e. less elastic, material. A higher resistance to impacts, scratches and/or chemicals can thereby be achieved.
  • Suitable lacquers of the mixture of lacquer and oil which can be used herein comprise, in a non-exhaustive list, corundum particles, acrylate, polymers, oligomers, additives and/or the like. So-called polyurethane lacquers (PUR lacquers) can also be used.
  • the lacquer of the mixture of lacquer and oil can in particular comprise a colored liquid plastic. PUR lacquers have the advantage that they are durable and scratch-resistant.
  • the mixture of lacquer and oil can be applied, for example, via spray nozzles, contact nozzles, vacumat coating, a transfer wheel and/or by means of similar means and/or methods.
  • the mixture of lacquer and oil is applied by vacumat coating.
  • the mixture of lacquer and oil consists substantially exclusively of lacquer and oil. However, it may be that further constituents are present in the mixture of lacquer and oil. These further constituents can be, for example, small amounts of solvents or agents having a comparable effect. These further constituents usually play a subordinate role and/or are present only in very small amounts in the mixture of lacquer and oil. Furthermore, smaller impurities can be present in the mixture of lacquer and oil.
  • a preferred embodiment relates to the laminate panel as described herein, wherein the weight ratio of oil to lacquer of the mixture of lacquer and oil is at least 5%, preferably at least 6%, preferably at least 7%, preferably at least 8%, preferably at least 9%, preferably at least 10%, preferably at least 11%, most preferably at least 12%.
  • the embodiment described above also has advantages with respect to production.
  • the weight ratio of oil to lacquer of the mixture of lacquer and oil can be adjusted, for example before application.
  • This adjusted weight ratio can then be used for the desired number of laminate panels (for example of particular types which have particular coupling elements, geometries and/or the like). These laminate panels then have substantially the same product quality.
  • the weight ratio can be adapted as desired for further types of laminate panels or in accordance with particular requirements.
  • the weight ratio can be stored permanently on a computer-readable storage medium and can then be easily retrieved when the need arise.
  • a preferred embodiment relates to the laminate panel as described herein, wherein the weight ratio of oil to lacquer of the mixture of lacquer and oil is at most 50%, preferably at most 45%, preferably at most 40%, preferably at most 35%, preferably at most 30%, preferably at most 25%, preferably at most 20%, preferably at most 19%, preferably at most 18%, preferably at most 17%, preferably at most 16%, most preferably at most 15%.
  • the oil should not have an excessively high proportion in the mixture of lacquer and oil. In particular, only so much oil should be applied that the desired effect of hydrophobizing the surfaces of the coupling elements of the at least one side surface of the carrier plate is achieved. An excessively high proportion of oil could have a disadvantageous effect on the costs.
  • a preferred embodiment relates to the laminate panel as described herein, wherein the oil comprises tung oil and/or linseed oil, wherein the oil preferably consists of tung oil and/or linseed oil.
  • the oil according to this embodiment has the advantage that it is relatively easy to procure. Furthermore, high hydrophobic effects can be achieved with even small amounts of oil, as a result of which the costs can be reduced.
  • Tung oil and linseed oil have the advantage that they are natural oils and consequently represent a gentle variant for laminate panels. These natural oils contain substantially no additives at all. Furthermore, these oils offer the advantage that a healthy room climate can be promoted. This is particularly noticeable if the laminate panels are installed and / or used in an interior area.
  • a preferred embodiment relates to the laminate panel as described herein, wherein the lacquer of the mixture of lacquer and oil comprises or consists of one or more of the following: corundum particles, acrylate, polymers, oligomers, additives, wherein the lacquer preferably consists of acrylate.
  • the lacquer can consist of acrylate-based lacquer.
  • the lacquer can be cured, for example, by UV radiation or electron radiation. It can also be the case that the lacquer of the mixture of lacquer and oil consists substantially of one of the materials described herein.
  • the lacquer can be an acrylate lacquer.
  • a preferred embodiment relates to the laminate panel as described herein, wherein the mixture of lacquer and oil is applied by point nozzles, contact nozzles, vacumat coating and/or a transfer wheel, preferably by vacumat coating.
  • the mixture can be applied quickly and efficiently to the surfaces of the coupling elements.
  • a preferred embodiment relates to the laminate panel as described herein, wherein the applied oil per meter of coupling elements in the longitudinal direction of the laminate panel is at least 0.1 grams, preferably at least 1 grams, more preferably at least 2 grams, more preferably at least 4 grams, more preferably at least 5 grams, more preferably at least 6 grams, more preferably at least 7 grams, more preferably at least 8 grams, more preferably at least 10 grams, more preferably at least 15 grams, more preferably at least 20 grams, most preferably at least 25 grams.
  • a minimum amount of oil should be used to render the side surface sufficiently hydrophobic, i.e. to make it substantially water-resistant.
  • a higher amount of oil usually leads to an improvement in the water resistance.
  • this trend of increased amount of oil and improvement in the water resistance is not linearly increasing and a saturation can be observed which resembles an asymptotic profile.
  • a preferred embodiment relates to the laminate panel as described herein, wherein the applied oil per meter of coupling elements in the longitudinal direction of the laminate panel is at most 100 grams, preferably at most 60 grams, more preferably at most 50 grams, more preferably at most 45 grams, more preferably at most 40 grams, more preferably at most 35 grams, more preferably at most 30 grams, most preferably at most 25 grams.
  • the oil should not be applied in unnecessarily high amounts to the coupling elements of the side surface, since the oil may be expensive and would thus make the laminate panel unnecessarily cost-intensive.
  • a preferred embodiment relates to the laminate panel as described herein, wherein the oil is applied to a surface of the coupling elements oriented perpendicular to the main surface of the laminate panel, preferably exclusively to the surface of the coupling elements oriented perpendicular to the main surface of the laminate panel, wherein the surface of the coupling elements forms an abutting edge with another correspondingly shaped laminate panel.
  • the surface of the coupling elements forming an abutting edge is usually arranged in the immediate vicinity of the main surface of the carrier plate. A part of this abutting edge can be visible from above (e.g., from a top view) in the case of two laminate panels connected via the coupling elements.
  • This surface usually constitutes a critical surface with respect to water resistance since the water first passes through this surface during ingress between two laminate panels. Consequently, it is advantageous if this surface is provided with oil. It can also be advantageous that exclusively this surface is provided with oil in order to reduce the costs for the laminate panel.
  • a preferred embodiment relates to the laminate panel as described herein, wherein the abutting edge has a thickness in the depth direction of the laminate panel of 0.2 mm to 10 mm, preferably 0.5 mm to 9 mm, more preferably 1 mm to 8 mm, more preferably 2 mm to 7 mm, more preferably 3 mm to 6 mm, most preferably 4 mm to 5 mm.
  • the abutting edge can have a thickness in the depth direction of the laminate panel of at least 0.2 mm, preferably at least 0.5 mm, more preferably at least 1 mm, more preferably at least 2 mm, more preferably at least 3 mm, more preferably at least 4 mm, more preferably at least 5 mm, more preferably at least 6 mm.

  • This thickness range of the abutting edge has proven to be advantageous in order to provide a substantially flush abutment between two laminate panels. As described herein, it can be advantageous if only this abutting edge is provided with oil.
  • the side surface comprises a chamfer forming the transition between the abutting edge and the main surface of the laminate panel.
  • the chamfer can be substantially straight or rounded.
  • the chamfer is substantially straight.
  • the chamfer can form an acute angle of at least 5 degrees, preferably at least 10 degrees, more preferably at least 15 degrees, more preferably at least 20 degrees, more preferably at least 25 degrees, more preferably at least 30 degrees with the main surface of the carrier plate.
  • the chamfer can form an acute angle of at most 80 degrees, preferably at most 70 degrees, more preferably at most 60 degrees, more preferably at most 50 degrees, more preferably at most 40 degrees, more preferably at most 35 degrees with the main surface of the carrier plate.
  • the oil can be applied exclusively to the chamfer or to the chamfer and to the abutting edge. In a further example, the oil can be applied to the entire profile of the coupling elements.
  • a preferred embodiment relates to the laminate panel as described herein, wherein the coupling elements in the cross-section perpendicular to the longitudinal direction of the laminate panel have a profile length of 5 mm to 50 mm, wherein of the profile length at least 5% is provided with oil, preferably at least 10% is provided with oil, more preferably at least 15% is provided with oil, more preferably at least 20% is provided with oil, more preferably at least 25% is provided with oil, most preferably at least 30% is provided with oil.

  • the profile length provided with oil can be a continuous length or can be composed of individual length sections, which in turn can be different or equal in length. However, it is advantageous if the profile length provided with oil represents a continuous length.
