Definitions

  • the invention relates to a wood-based panel, in particular OSB panel, which has at least one upper cover layer, at least one middle layer and at least one lower cover layer, all of which consist of resin-coated strands and processes for their production in the resin-coated layer and as at least one lower cover layer.
  • a wood-based panel in particular OSB panel, which has at least one upper cover layer, at least one middle layer and at least one lower cover layer, all of which consist of resin-coated strands and processes for their production in the resin-coated layer and as at least one lower cover layer.
  • at least one topsheet and at least one middle layer forming strands are provided separately, the strands of the backsheet being deposited in a first orientation substantially longitudinal to the panel direction, the strands of the midlayer in a second orientation substantially transverse to the panel main direction on the backsheet are stored, the strands of the upper cover layer are placed back in the first orientation on the middle layer and a lower cover layer, middle layer and upper cover layer existing layer structure under increased pressure
  • From the DE 44 34 876 A1 is a method for producing a coated wood-based panel is known in which with resin-coated wood chips in several layers too a chip cake are sprinkled and the wood chips are arranged in the first layer and in the last position substantially in alignment.
  • Coated wood-based panels are used as furniture panels, as building elements, as shuttering panels or as floor panels.
  • walkable formwork panels e.g. In the roof area and in the floor slabs, it is important for the safety of the craftsmen that the wood-based panels have a non-slip surface, so that e.g. A roofer does not slip when walking the roof formwork.
  • Floor slabs are used in the commercial sector, e.g. used in the work area of woodworking machines. To ensure that workers have a firm footing when operating the machines and that the risk of slipping accidents is eliminated, the floor slabs must be non-slip. Frequently, floorboards, in particular OSB boards, which have a smooth surface and are not slip-proof, must be retrofitted with an anti-slip coating, e.g. made of sand, to meet the requirements of occupational safety.
  • an anti-slip coating e.g. made of sand
  • the grinding of the outer layers is particularly disadvantageous in OSB boards, which are used outdoors as roofing or facade board, because by the grinding of the surface on the one hand, the moisture resistance is reduced, since the water-repellent press skin (Harzverflustik) is abraded or reduced, and the other Bending strength of the wood-based panels decreases because the marginal layers, which have the greatest bulk density and thus strength, are ground down.
  • coatings such as paints, screeds, plastic or mineral plasters on OSB boards, because the adhesion of these coatings to the OSB boards is reduced due to the press skin.
  • a generic OSB board is characterized in that the OSB board has fabric fibers in the upper and / or the lower cover layer.
  • fabric fibers of varying length, thickness and texture can be incorporated into the cover layers.
  • the tensile strength of the cover layers can be adjusted to the particular intended use of the OSB plate.
  • the generic OSB board has at least one fabric layer on the surface of the upper and / or the lower cover layer.
  • the flexural properties of the OSB board are also increased.
  • the fabric layer on the opposite side of the force acting, the tension side arranged.
  • the technical properties of the wood-based panel in particular the flexural and modulus of elasticity, the flexural strength, the swelling behavior and the fire behavior are improved.
  • the OSB board can serve as a carrier material for applied paint, screed or plaster systems that can be applied directly.
  • the fabric layer creates a slip-resistant surface on the OSB board, which enables the use of these OSB boards in new applications, such as in the roof formwork or in the stage covering area. For these applications, the fabric layer is placed on the top of the board.
  • the fabric layer has a weight of at least 50 to 400 g / m 2 , preferably 200 g / m 2 , so that a significant increase in flexural strength, as well as an improvement of the swelling and shrinkage behavior of the OSB board is realized.
  • the fabric insert may have a resin impregnation and / or a glue layer.
  • a paper layer can be applied below the fabric layer.
  • the paper layer to a weight of at least 50 to 400 g / m 2 , preferably 80 to 100 g / m 2 .
  • the paper layer may have various optical designs and so create a decorative effect on the plate, such as signal colors for walk-roofing slabs.
  • the paper layer may have a resin impregnation and / or a glue layer,
  • At least one fabric layer may be provided on the surface of the upper and / or lower cover layer.
  • the OSB board may have a fabric layer with a weight of at least 50 to 400 g / m 2 , preferably 200 g / m 2 .
  • the fabric layer may have a resin impregnation and / or a glue layer.
  • a method for producing a generic wood-based panel is characterized in that tissue fibers are provided and the fabric fibers are added to the strands for the lower cover layer and / or the upper cover layer.
  • the process for producing a wood-based panel proceeds in a continuous process, since in this way a uniform application of lower and / or upper outer layer to the forming belt is achieved and continuous addition of the fabric fibers to the strands. It is particularly advantageous that the entry of the fabric fibers no additional equipment or equipment parts must be provided, and so the production costs are particularly low.
  • Another generic method for producing a wood-based panel characterized by the fact that at least one layer of fabric is applied to the upper cover layer and / or on the lower cover layer before pressing.
  • the QSB plate thus obtains a non-slip surface, such that the OSB board is e.g. can be used as walk-in roofing or as a stage covering.
  • At least one layer of paper may be applied to the upper cover layer and / or the lower cover layer prior to the application of the fabric layer in order to further improve the resistance of the OSB plate to moisture absorption and the flexural strength of the OSB plate. If the method for applying the fabric layer to the upper cover layer and / or to the lower cover layer proceeds continuously, on the one hand costs for additional machines can be saved and on the other hand a uniform application of the fabric layer to the upper and / or the lower fabric layer can take place ,
  • tissue fibers are provided, the fabric fibers are added to the strands for the lower and / or upper cover layer and the at least one layer of fabric on the upper cover layer and / or on the lower cover layer is applied.
  • an OSB board with particularly good strength properties, with an improved swelling and shrinkage behavior as well as a good plasterability and a non-slip surface can be produced.
  • These OSB boards are suitable for applications with particularly high demands, for which conventional OSB boards are not suitable.
  • this process proceeds continuously in order to achieve both the uniform distribution of the fabric fibers in the upper and / or the lower cover layer and to realize a uniform application of the fabric layer to the upper and / or lower cover layer cost-effectively.
  • FIG. 1 shows an OSB board 1, consisting of an upper cover layer 2, a middle layer 3 and a lower cover layer 4 of long, glued chips.
  • a paper layer 7 and a fabric layer 5 is applied on the upper side of the cover layer 2.
  • Fabric and paper layers 5, 7 each have a glue layer 6, 8, which fixes the paper 7 or the fabric 5 on the cover layer 2 of the OSB board 1.
  • the fabric layer 5 serves the purpose of providing a non-slip surface on the OSB board 1.
  • the OSB board 1 can also be used in applications in which they could not be used because of the smooth surface, for example, as a roof formwork panel or in the stage covering area.
  • the fabric layer 5 is arranged on the surface of the upper cover layer 2.
  • FIG. 2 shows a process diagram for producing an OSB board 1.
  • the strands are scattered in conventional processes on a continuous circumferential forming belt to a layer structure 9, wherein the states of the two cover layers 2 and 4 are deposited substantially along the plate main direction x.
  • the Gewebefasem be mixed. This leads to an increase in the tensile strength of the outer layers 2 and 4 and therefore has a positive effect on the bending properties of the OSB board 1.
  • a fabric layer 5 is given to the layer structure 9 and pressed together with this in the hot press.
  • the fabric layer 5 has the task of increasing the bending properties of the OSB board 1.
  • the OSB plate 1 For this purpose is used the OSB plate 1, the fabric layer 5 on the opposite side of the force acting force (tension side).
  • the fabric layer 5 reduces the swelling and shrinkage behavior of the OSB board 1.
  • the OSB board 1 can serve as a carrier material for applied paint, screed or plaster systems.
  • the fabric layer 5 also produces a slip-resistant surface.
  • only fabric fibers of one or both of the outer cover layers 2, 4 can be mixed in or, before the inlet of the layer structure 9 in the hot press alone or additionally, a fabric layer 5 can be placed on the upper cover layer 2.
  • FIG. 3 shows the density progression over the thickness of the OSB board 1.
  • gross density maxima are shown, which indicate that the strength of the OSB board 1 is particularly high, especially in these outer areas.
