Definitions

  • the present invention relates to a method for producing an OSB provided with a printed surface, according to the preamble of claim 1. Such a method is known from document EP 3 290 175 A1 known.
  • HWS wood-based materials
  • OSB oriented strand board
  • This board which is also known colloquially as coarse chipboard, is made from thin, flat chips (strands).
  • OSB takes place in a multi-stage process, whereby first the long, flat chips (strands) made of debarked round wood, especially softwood, are peeled off in the longitudinal direction by rotating knives.
  • the strands typically have a length between 50-200 mm, a width between 5-20 mm and a thickness between 0.1 and 1 mm.
  • the strands are fed into a gluing device, in which glue or adhesive is applied to the strands in a finely distributed manner.
  • PMDI polymer diphenylmethane diisocyanate
  • MUPF glue melamine-urea-phenol-formaldehyde
  • the glued strands are scattered alternately lengthwise and crosswise to the production direction in scattering devices, so that the strands are arranged crosswise in at least 3 layers (lower cover layer, middle layer, upper cover layer).
  • the scattering direction of the strands is rotated by 90° from one layer to the next.
  • the scattering direction of the strands and the long, slender, flat shape of the strands also result in the high flexural strength of OSB material panels, which is important for many applications.
  • Another advantage is that this product has a lower bulk density (approx. 650 kg/m 3 ) compared to other wood-based materials due to the use of coniferous wood during manufacture.
  • the geometry and scattering of the strands usually does not lead to a closed surface in OSB, but to a structure with depressions that can be up to several millimeters deep. These indentations or holes accelerate water penetration into deeper areas of the OSB during rain or other stresses where water is present. This can lead to undesired swelling with a deterioration in the strength values and, for example, cause an increase in weight after a rain event due to the additional water absorption.
  • the OSB can also quickly become dirty or chemicals can penetrate the surface of the board, which can cause glue hydrolysis or color changes.
  • a carrier board with a high raw density leads to handling problems during assembly with larger format boards. It is also known that wet-process fibreboards containing phenolic resin as a binder tend to warp when climatic conditions change. For this reason, these panels are usually only used in small thicknesses and/or only small formats.
  • the invention is therefore based on the technical problem of developing a method which, at low additional costs, produces an OSB which has a surface which can be printed on. At the same time, this surface is intended to act as a moisture barrier that prevents water from penetrating.
  • this object is achieved by a method for producing an OSB provided with a structured surface with the features of claim 1 .
  • a hot-melt adhesive (hotmelt) is applied to the surface of the OSB, the hot-melt adhesive layer filling the surface (filling of the depressions) of the OSB.
  • the application of the plastic resin in the form of a hot-melt adhesive or hot-melt can be carried out in parallel with a smooth roller. This allows a bead to form on the OSB in front of the roller, which is able to fill up the indentations on the OSB surface.
  • the hot melt also impregnates the strands, which not only leads to the expected water repellency of the wood, but also creates a wood-plastic laminate. This could be made possible by the fact that the strands have a very large surface after drying and that there are many cavities in the wood itself that can be easily filled with hotmelt.
  • a second, heated roller preferably runs in the opposite direction over the still plastic hotmelt surface and carries out further smoothing. This process can also take place in two parts, i. H. After the hotmelt coating, the OSB is initially stored temporarily and then smoothed out in the next step. However, not too much time should elapse between steps 1 and 2, since a polyurethane hotmelt continues to crosslink with moisture.
  • the hot-melt adhesives used according to the invention are typically solvent-free products which are usually solid at room temperature and are applied to an adhesive surface in the molten state and cause a solid connection to form on cooling.
  • the adhesive properties are accordingly brought about by solidification due to cooling and not by hardening associated with a chemical crosslinking reaction.
  • Typical areas of application are e.g. the coating of edges, surface bonding, as a pressure-sensitive hot-melt adhesive on envelopes or use as a wrapping adhesive.
  • the use of hot-melt adhesives as a surface coating for OSB is not known to date.
  • the at least one hot-melt adhesive is selected from a group containing polyurethane, for example thermoplastic polyurethanes, polyamide, ethylene vinyl acetate, polyester or polyolefin.
  • the material is selected with regard to the intended area of application and the the resulting stresses in terms of temperature, chemicals, water, etc. If EVA, polyamide or polyolefin is used, the resin layers are preferably solidified by cooling. Polyurethane and polyolefin are preferred because of their higher heat resistance (>100° C.).
  • the use of polyurethane has the further advantage that post-crosslinking with the wood surface takes place, resulting in particularly good adhesion to the beach surface.
  • the hot-melt adhesive used is applied according to the invention at a temperature that is above the application temperature recommended by the manufacturer (which roughly corresponds to the melting temperature of the adhesive). Due to the increased temperature of the hot-melt adhesive, the viscosity of the hot-melt adhesive is reduced and enables better penetration of the hot-melt adhesive into the wood structure. At the same time, the wooden strands are impregnated on the OSB surface.
  • the hot-melt adhesive is applied at a temperature which is 10 to 50° C., preferably 25 to 45° C., above the usual processing temperature or application temperature of the hot-melt adhesive.
  • the manufacturer's recommended application temperatures for the hot melt adhesives vary depending on the chemical composition of the hot melt adhesives. Typical application temperatures for polyamides are above 200°C, for polyethylene between 140 and 200°C, or for EVA around 150°C.
  • a polyurethane hotmelt variant with a normal processing window between 130 and 150°C is now used, this is preferably applied at a temperature of 170-180°C (e.g. 175°C).
  • application preferably takes place at a temperature of 210-220°C (e.g. 210°C).
  • the at least one hot-melt adhesive layer is applied at a temperature between 150 and 250°C, preferably between 170 and 210°C, particularly preferably between 180 and 200°C.
  • the viscosity of the hotmelt adhesive to be applied can be in a range between 5500 and 6200 mPas (Brookfield) for a polyurethane hotmelt or in a range between 13000 and 15000 mPas.
  • the use or application of a hot-melt adhesive with a higher temperature (and reduced viscosity) also enables the strands to be impregnated, which not only makes the wood hydrophobic but also results in the formation of a wood-plastic laminate. This is due to the fact that the strands have a very large surface after drying and there are also many cavities in the wood itself that can be filled with the hot melt adhesive. It is also possible to also provide the second side (underside) of the OSB with a layer of hot-melt adhesive, for example in an amount of 50 to 150 g/m 2 , preferably 100 g/m 2 . The same processing conditions as described above are selected.
  • the at least one decorative layer is applied using the digital printing process.
  • a water-based pigmented printing ink can be applied using the digital printing process.
  • This water-based pigmented ink can also be applied in more than one layer, for example two to ten layers, preferably three to eight layers.
  • the at least one decorative layer can be applied by means of an analog gravure printing process and/or according to the invention by means of a digital printing process.
  • Intaglio printing is a printing technique in which the elements to be imaged are indented in a printing form which is inked prior to printing.
  • the printing ink is mainly in the indentations and is transferred to the object to be printed, such as a wood fiber board, due to the contact pressure of the printing form and adhesive forces.
  • digital printing on the other hand, the printed image is transferred directly from a computer to a printing machine, such as a laser printer or inkjet printer. This eliminates the use of a static printing form.
  • the aqueous paints and inks or colorants are UV-based.
  • step d) of printing is carried out directly on the smoothed layer of hot-melt adhesive; i.e. the previous application of primer layer and primer, which is otherwise usual with wood-based panels, is dispensed with.
  • the hot-melt adhesive layer fulfills the function of a primer/undercoat layer. Accordingly, the OSB panel coating produced in this way is free of a primer and grounding layer.
  • the use of a primer and an undercoat can be dispensed with when using UV inks. It is particularly positive that due to the large-area strands in the top layer when printing without prior priming, the strands under pressure contribute to the decor impression.
  • a further embodiment provides for the use of a colored hot-melt adhesive. This has the advantage that you can change the color of the primer relatively quickly. Only several hotmelt application units then have to be available. Either a part or the complete priming can be carried out with the hot-melt adhesive, which can be colored in any colour. Of course, in both cases a partial or complete blocking off of the underground can be achieved. It just depends on the desired decorative effect.
  • water-based inks can also be used, which are printed onto the hotmelt surface, primed if necessary. This creates prints that produce a surprising, veneer-like decor impression in wood reproductions.
  • digital printing can be used to give the prints a used look. This can be particularly advantageous if the products are later used for outdoor applications (façade). Yellowing/fading can be produced there directly via the print.
  • the substrate can of course be sealed off by applying a primer.
  • at least one primer layer is applied to the carrier plate, at least one primer layer is then applied to the same, for example in the form of a UV or ESH spatula.
  • the amount of liquid primer applied would then be between 1 and 30 g/m 2 , preferably between 5 and 20 g/m 2 , particularly preferably between 10 and 15 g/m 2 .
  • a composition of casein as a binder and inorganic pigments, particularly inorganic color pigments, could be used as the undercoat layer.
  • White pigments such as titanium dioxide (TiO 2 ) can be used as color pigments.
  • Other color pigments can be calcium carbonate, barium sulfate or barium carbonate.
  • the primer also contains water as a solvent.
  • the at least one (first) lacquer layer is applied to the at least one in an amount between 30 and 150 g/m 2 , preferably between 50 and 120 g/m 2 , preferably between 60 and 100 g/m 2 Decorative layer applied.
  • radiation-curable, acrylate-containing paints are used as paints, which have high UV stability and good resistance to the effects of weather.
  • the radiation-curable lacquers used for this purpose typically contain methacrylates, such as polyester (meth)acrylates, polyether (meth)acrylates, epoxy (meth)acrylates or urethane (meth)acrylates.
  • the acrylate used or the acrylate-containing lacquer has substituted or unsubstituted monomers, oligomers and/or polymers, in particular in the form of acrylic acid, acrylic ether and/or acrylic acid ester monomers, oligomers or polymers.
  • the acrylates mentioned enable crosslinking in the presence of UV radiation or electron beams in the curing or drying process.
  • isocyanate acrylates are preferably used as paints, non-aromatic, aliphatic isocyanates, such as hexamethylene diisocyanate, isophorone diisocyanate, or prepolymers containing these isocyanates being particularly preferred as the isocyanate component.
  • the coating layer(s) can be applied in a coating line using one or more casting heads or roller application units.
  • the paint layers can be hardened with an electron beam.
  • the first lacquer layer can contain abrasion-resistant particles.
  • the abrasion-resistant particles are preferably selected from the group containing aluminum oxides, corundum, boron carbides, silicon dioxides, silicon carbides and glass beads.
  • the first lacquer layer contains 10-30% by weight, preferably 20% by weight, of corundum.
  • At least one further second lacquer layer is applied to the first lacquer layer.
  • This additional second lacquer layer can be applied in an amount between 10 and 50 g/m 2 , preferably between 15 and 30 g/m 2 , preferably between 20 and 25 g/m 2 .
  • This further, second coat of paint can also be referred to as the grinding base.
  • the acrylates mentioned above are also used here.
  • topcoat layer is applied in an amount between 5 and 50 g/m 2 , preferably between 6 and 20 g/m 2 , preferably between 7 and 10 g/m 2 .
  • the acrylates mentioned above are also used here.
  • the top coat of paint can also be cured using excimer radiation.
  • the excimer radiation also causes additional cross-linking of the monomers, which increases the surface hardness.
  • the entire layer structure is then subjected to final through-hardening in the ESH radiator.
  • the present method makes it possible to provide a printed OSB panel.
  • the printed OSB board thus comprises an OSB carrier board, a smoothed hot-melt adhesive layer provided at least on one surface of the OSB carrier board, at least one decorative layer provided on the smoothed hot-melt adhesive layer and at least one lacquer layer provided on the decorative layer.
  • the printed OSB panel has the following layer structure: OSB core panel, a smoothed hot-melt adhesive layer provided at least on one surface of the OSB core board, at least one decorative layer provided on the smoothed hot-melt adhesive layer, in particular in direct printing applied decorative layer, at least one lacquer layer provided on the decorative layer and at least one top lacquer layer.
