Definitions

  • the invention relates to a method for producing acoustic structural panels according to the preamble of claim 1, and to an acoustic structural panel according to the preamble of claim 10.
  • Such sound-absorbing building board is used mainly for the lining of interior walls, in particular as wall or ceiling panels. It can also be used as a door panel or door.
  • Sound-absorbing building panels are used where the acoustic conditions of a room are to be influenced.
  • the most widely used is as a ceiling tile, although sound-absorbing wall panels are installed.
  • porous panels are used, eg particle board or mineral fiber boards. These panels are themselves sound-absorbing and can be used without additional sound-absorbing equipment for the production of acoustic wall or ceiling panels.
  • the panels are self-supporting and can be manufactured with relatively large dimensions due to their load capacity. It is also known to coat such sound-absorbing structural panels on their visible side with a microporous film.
  • the main purpose of the microporous film is to provide a different surface structure without concomitant deterioration the sound-absorbing properties, since sound-absorbing panels can not always meet aesthetic requirements.
  • an acoustic panel in sandwich construction is from the EP 873 453 known.
  • the support structure is provided in the form of a carrier plate with an adhesive grid, wherein the adhesive due to the grid should affect the porosity of the acoustic panel little.
  • a disadvantage is that by the lamination process, in which the cover layer is applied to the support structure, yet the adhesive reduces the porosity of both the support plate and the cover layer.
  • the invention is therefore based on the object to provide a method for producing a building board and an acoustic building board, in which the manufacturing process is simplified and the sound-absorbing properties of the building board are improved.
  • the invention advantageously provides that the cover layer is provided with a microperforation by means of laser light after lamination.
  • the micro-perforation produced by laser light creates micropores which penetrate the cover layer, an adhesive layer between the cover layer and the support structure and intermediate layers possibly arranged between cover layer and support structure.
  • Another advantage is that the microperforation is produced only after lamination and can be done in a particularly advantageous manner during lamination when applying the cover layer.
  • a chipboard or wood fiber board can be used with a bulk density of 300 to 500 kg / m 3 , with a bulk density of 400 kg / m 3 is preferred. All integer intermediate values between 300 and 500 kg / m 3 should be considered disclosed.
  • the microperforation can be generated computer-controlled with the laser light, producing a uniform or non-uniform grid structure can.
  • the cross-sectional shape of the micropores can also be programmed.
  • the micropores may, for example, have a slot-shaped, triangular and / or square and / or honeycomb microporous structure.
  • micropores at an oblique angle to the surface of the cover layer. This has the advantage that the visibility of the micropores is reduced.
  • the micropores have a diameter between 200 and 600 microns, each integer intermediate value should be considered disclosed. Preferably, a diameter of the micropores of about 400 microns is provided.
  • the pore area of the microperforation should be more than 10% of the topcoat area and preferably in the range between 12 and 15%.
  • the number of micropores of the microperforation is between 500,000 and 2 million micro pores / m 2 , preferably between 800,000 and 1.2 million micro pores / m 2 , each integer intermediate value should be considered disclosed. In particular, a value of about 1 million micropores / m 2 has been proven.
  • the support structure may be laminated on one or both sides with a nonwoven fabric, which already has a porous structure of its own accord.
  • the acoustic structural panel 1 shown in FIG. 1 serves to cover interior surfaces in the form of a wall or ceiling panel and has a support structure 2 which is laminated with a porous cover layer 3.
  • the cover layer 3 is laminated to the support structure 2 with a jacket adhesive, for example an EVA adhesive.
  • the cover layer forms a decorative layer of a printable or a printed decorative paper.
  • a decorative paper with 60 g / m 2 is used.
  • the paper may in principle have a basis weight between 40 and 180 g / m 2 .
  • a wood veneer or a plastic film in particular a CPL film (such as Resopal) can be used.
  • the microperforation with approx. 1 million micropores / m 2 produces a surface with a pore content of approx. 12%.
  • the micropore diameter is preferably 400 ⁇ m.
  • the microperforation is generated with one or more scan heads with rotating mirrors, wherein the laser light is redirected to the cover layer via the rotating mirrors. Multiple lasers can be used to increase the production speed.
  • the support structure 2 may consist of a softboard, a micro Strandboard plate or other coatable carrier.
  • the bulk density is preferably in the range of 400 kg / m 3 .
  • the laser light can in particular penetrate adhesive layers between the cover layer 3 and the support structure 2, so that the sound-absorbing properties of the acoustic building board 1 are improved.
  • the wall and ceiling panels may be provided at their outer edges with positive fasteners, e.g. Tongue and groove elements and also be provided with latching fasteners (Click connections).
  • positive fasteners e.g. Tongue and groove elements and also be provided with latching fasteners (Click connections).
  • the support structure 2 may be laminated on one or both sides with a nonwoven fabric layer 5.
  • a nonwoven fabric layer 5 is, for example, a polyester spunbond with a basis weight of 50 g / m 2 .
  • FIG. 2 shows an exemplary embodiment in which the cover layer 3 forming a decorative layer is laminated onto the support structure 2 directly with the aid of an adhesive layer (not shown in the drawing).
  • FIG 3 shows an exemplary embodiment with an additional nonwoven fabric layer 5 between cover layer 3 and support structure 2.
  • the laser-generated micropores 4 make it possible to produce wall and ceiling panels with improved acoustic performance and an improved high-quality surface.
