Definitions

  • Wood materials that are processed into panels are usually surface-coated.
  • the surface coating only the actual serviceability of the panels, since they decor, water resistance, abrasion resistance, chemical resistance, possibly stock against algae, fungi and / or insects lend.
  • the surface coating is usually carried out by a coating of the panel with a resin impregnated decorative paper.
  • the AT 351,744 describes the painting of a chipboard, wherein a first paint job is referred to as a primer.
  • the primer is applied to both surfaces, top and bottom of the chipboard.
  • a second paint job follows.
  • the second lacquer layer is applied on one side only on the upper side of the chipboard.
  • the paint application is at least 50 to 500 g / m 2 .
  • the method proposed here dispenses with decorative paper. The aim is to save expensive equipment such as presses. In fact, however, the synthetic resin predominantly proposed here for the coating layers is melamine, one of the most expensive coating components.
  • UV-curable coatings brings here remedy.
  • An example of the use of UV-curable coatings shows the US 4,439,480 .
  • an intermediate grinding is hitherto also preferred when using UV-curing paints, especially when - as in the US 6,475,623 - multi-layered and relatively thick surface coatings are used.
  • the panel of wood material is coated according to a simple embodiment of the invention with a primer and, building on it, with at least two layers of paint. It has, however to achieve useful strength and wear properties proved sufficient to apply only very little paint.
  • the coating of lacquer, the layer thickness is less than 120 ⁇ m in total, preferably less than 80 ⁇ m, more preferably less than 60 ⁇ m, advantageously less than 45 ⁇ m, particularly advantageously less than 30 ⁇ m.
  • corundum is incorporated as a functional component in a lacquer layer, which is not the outermost lacquer layer.
  • the varnish which essentially determines the performance characteristics of the panel, is applied in two or more layers.
  • the above-mentioned layer thickness of up to 120 microns in total is not exceeded.
  • the surface coating of the panel is substantially improved.
  • the application of several thin layers of lacquer improves the load-bearing capacity or the resistance of the lacquer layer as a whole, making the coating more durable.
  • a thin lacquer layer is understood as meaning a lacquer layer of up to 20 ⁇ m, preferably of up to 15 ⁇ m, advantageously of up to 10 ⁇ m.
  • the at least two thin lacquer layers are preferably applied in such a way that in each case an already applied layer is gelatinized, and then already the next layer is applied.
  • an already applied layer is gelatinized, and then already the next layer is applied.
  • the individual layers thin and -ggf. by angelieren- sufficiently smoothly applied.
  • the quality, in particular the smoothness of the thin lacquer layer also satisfies high optical and mechanical quality requirements.
  • the lacquer layer applied according to the invention in a thin layer can be cured or reacted out with ultraviolet light (UV light) or by electro-jet hardening ESD, depending on the choice of the lacquer; the latter can also be used without the use of photoinitiators.
  • UV light ultraviolet light
  • ESD electro-jet hardening
  • the application of various UV-curing lacquers is used to apply different lacquers, in particular matt lacquers and gloss lacquers, in layers, these layers covering the surface of the panel in sections. Matt varnish is applied in sections as a functional layer. In addition, a lacquer layer of gloss lacquer is applied. Already this simple two-layer surface coating allows optical effects.
  • layers of matt varnish and gloss varnish are arranged in their layer sequence such that optically perceivable structures are formed. These structures are characterized by the fact that viewers perceive supposedly three-dimensional patterns. These plastic-looking patterns from a succession of gloss varnish and matt varnish layers can be used for the design of fantasy decors, but also for the reproduction of natural decors. Here, in particular, the replica of pore structures to think.
  • An alternative to the production of optically perceivable structures can likewise be implemented according to the invention by introducing at least two functional layers.
  • a first functional layer which partially covers the surface of the panel, and which repels a coloring coating
  • at least one second layer which consists of a coloring coating, which covers the surface of the panel in sections.
  • a first functional layer can be applied in sections with waxes or oils, which are the application of color or of a coloring coating to the surface of the wood material prevented. In this way, visually perceptible structures are generated.
  • inventions of panels of wood-based material with visually perceptible structures by applying one or at least two functional layers preferably have surface coatings in which at least one functional layer is covered by at least one lacquer layer.
  • the surface coating has at least one functional component which may be applied as an outer layer or as a layer arranged between the at least two lacquer layers. It should be emphasized that the at least one functional component combines well with the material of the paint layer. If the at least one functional component is applied as a layer, then the at least one functional layer bonds well with the paint layer (s). UV-curing paints are surprisingly extremely tolerant to functional components. The hardening and building up of a uniform surface coating is well possible according to the invention despite different combinations of functional components or layers of lacquer and other substances.
  • the surface coating may also have two or more different functional components or layers. By way of example, mention may only be made of a layer for impact sound insulation and a layer for improving the fire resistance or two coloring layers and a layer of lacquer to which a functional component is added for adjusting the absorption of UV light.
  • Additional components not belonging to the invention are often incorporated in one of the at least two paint layers, in particular if this forms the outer layer of the surface coating.
  • the scratch resistance, the abrasion, the gloss but also properties such as an antibacterial effect or dissipative properties of the panel by selecting the appropriate UV or radiation-curing paint but also by selecting suitable components such.
  • a main area of use for panels is in addition to the use as ceiling or wall coverings or countertop and the use as a floor covering.
  • the suitability as a floor covering depends essentially on whether the surface of the panel is sufficiently resistant to the abrasion caused by the walking of the floor or the wear of chair castors and other objects. So that the usage parameters such as Abriebeigenschaften, chair roll resistance, stain resistance and the like of panels are comparable, are defined in EN 13329 classes of use for laminate, ie for wood-based panels, which are provided with a surface coating of decorative paper
  • the use classes distinguish between the use of panels for residential purposes and for commercial purposes.
  • the panels according to claim 1 in particular the floor panels, but also with countertops is dispensed with in the context of the surface coating just on the decorative paper. This is replaced by the extremely low paint application.
  • the panels according to claim 1 using the EN 13329 classes of use are assigned, which are in any case the demands on residential demand fair.
  • the product according to claim 1 is tested and evaluated using the same testing method prescribed by DIN EN 13329 for laminate. So z.

  • the elastic properties of these materials greatly improve the room acoustics as well as the sound insulating properties of the panel. In particular, the improved impact sound insulation through the use of EVA should be emphasized.
  • a damping effect on the joints of persons who make these floor panels is also to be observed.
  • Such with functional components or layers providing panels are particularly suitable for sports halls.
  • the sound-insulating properties come, for example, in wall or ceiling panels whose surface is increased, especially for effect.
  • the elastomer is applied in a layer thickness of 0.1 mm up to 10 mm. Even a single layer of an elastomer contributes significantly to the insulation of impact sound.
  • UV-absorbing substances or compounds are usually metal compounds, in particular metal oxides such as zinc oxide, for which it is known that they reflect UV light or absorb. Preferred is or this substance is transparent. It is further preferred if this functional component is used in the final lacquer layer, or is arranged at or near the surface of the surface coating. It has a special protective effect when applied above coloring or UV-light changeable coatings.
  • a flame retardant or fire resistance of the wood material increasing substance is used as an additional component.
  • Flame retardant or fire resistance improving substances are known per se. These include, for example, water glass or other inorganic substances such as vermiculite. Preferably, transparent substances are also used here.
  • Genörend As additional component preferably also a substance or a mixture of substances is used, with which the sliding resistance of the surface of the wood material is to be adjusted. Typical substances are wax or oils or mixtures thereof, but also mineral substances, especially fine-grained sand.
  • This layer is preferably arranged as an outer layer of the surface. It is also advantageous to incorporate into the surface coating of a panel at least one component with which the haptic properties of the surface of the wood-based material or the coated panel are to be set.

Paints are known and available which shrink very differently when applied and cured on wood-based materials within a wide range.
