Definitions

  • the invention relates to a composite panel according to claim 1.
  • Construction panels for the furniture and building materials industry with cellulose-containing components are primarily wood-based panels but also solid wood panels, gypsum fiber and plasterboard panels as well as calcium silicate panels and the like. These panels are used for a wide variety of purposes, such as in furniture and interior design, for interior doors, for packaging, in construction, etc. Porous wood-based panels are used for heat and sound insulation purposes.
  • wood-based panels a distinction is made between wood chipboard and wood fiber boards as well as OSB and plywood boards.
  • wood fiber boards shredded wood is hot pressed, for example by production in a hydrothermal pretreatment in a disc refiner, after the addition of synthetic binder.
  • wood fiber boards can use the inherent cross-linking properties of the fiber material, with fiber matting being important.
  • condensation resins as binders, for example urea-formaldehyde or melamine-formaldehyde or phenol-formaldehyde (formaldehyde resins) or polyaddition resins such as PMDI adhesives or mixtures of these resins.
  • condensation resins for example urea-formaldehyde or melamine-formaldehyde or phenol-formaldehyde (formaldehyde resins) or polyaddition resins such as PMDI adhesives or mixtures of these resins.
  • the size, shape and arrangement of the chips and the amount of synthetic resin content can vary the properties of the chipboard.
  • High-quality chipboard is produced in multiple layers with particularly fine covering chips. It is also generally known to provide wood-based panels with single- or multi-layer coatings, for example melamine coatings, decorative films, funtions, etc.
  • wood-based panels For example, their surface quality is essential for a surface coating. Mechanical properties such as compressive strength and bending stiffness are important for certain applications. Furthermore, the wood-based panels have to withstand weathering in certain areas of application or have moisture, fire or soundproofing properties that are matched to the application. Wood-based panels are also coated for optical reasons, but in particular in order to counter mechanical stresses or to form a protective layer against the effects of weather and radiation, and for example for scaffolding panels with anti-slip coatings and special concrete formwork panels with release properties.
  • Flawed surfaces can also appear on plywood panels when inferior veneers are used.
  • a single grinding process is usually not sufficient to achieve a surface that can be coated.
  • the imperfections in the surface must be filled so that the imperfections in the subsequent coating do not appear on the surface finish through the coating material, or to prepare the material for a coating. Flaws of this type are filled, for example, by doctor blade systems in which the raw plate surface is filled with filler. After the filler has dried, the calibration is carried out.
  • the invention has for its object to provide a composite panel on the basis of a construction panel for the furniture and construction sector, in particular a wood-based panel, which does not have the disadvantages mentioned above and can be provided with a desired surface without complex measures and, if necessary, has an excellent coatability.
  • the composite panel according to the invention consists of at least two layers, e.g. a wood-based panel with a coarse, open-pore and / or porous surface structure and at least one second layer.
  • the second layer is applied to at least one side of the construction board. It consists of a composite material which in turn consists of a web-like carrier material which is impregnated with a hardenable, not fully hardened resin and contains expandable thermoplastic particles and a solvent with not more than 40% by weight.
  • Such a second layer is connected to the wood-based panel by heat and possibly by pressure.
  • a composite as specified in claim 1, has become generally known from EP 0 647 182 B1. It is intended to be connected to one or more other laminate materials, for example a foamed plastic, a woven or non-woven organic or inorganic fiber material, an expanded metal or the like.
  • the composite material forms the core layer, while the other laminate material is applied to the core layer on one or both sides.
  • the application is done by hot pressing, whereby the semi-finished composite reacts and the thermoplastic particles, for example microspheres, expand and the resin cures.
  • the invention provides for the use of such a composite on construction panels, in particular wood-based panels for the furniture and construction sectors, the properties and / or surfaces of which are significantly improved as a result.
  • the composite Due to its properties, the composite is self-adhesive on the surface of the construction panel, the composite foaming during the hot pressing process due to the embedded thermoplastic particles.
  • the second layer is therefore pressed by a heat-foaming, self-adhesive web reinforced with a carrier material under the action of heat and possibly pressure to form a coating on the surface of the construction panel.
  • the second layer according to the invention can be placed as an additional layer on the ground or unground surface of the construction plate.
  • the composite material is therefore glued and foamed with the addition of pressure and heat, so that a closed, calibrated and ready-to-coat surface is produced in one operation after the end of the process.
  • the connection of the construction board, eg wood-based board, and composite material can take place in conventional pressure-controlled pressing devices or also in path-controlled pressing devices.
  • a commercially available coating material self-adhesive or non-self-adhesive
  • a commercially available coating material can also be placed on the second layer, so that a closed, calibrated and completely coated surface is produced with a pressing process.
  • a surface is obtained which can be coated with any material, e.g. also with metal or plastics.
  • a desired surface structure can be produced on a large scale, for example by pressing with embossing rollers or embossing sheets or negative molds, the embossing depth being able to exceed the thickness of the finish material. This is made possible by the foaming process of the second layer.
  • Loose crystalline materials such as Quartz sand can be applied to the wood-based panel with the second layer.
  • the composite acts as a primer film.
  • the second layer serves as a water-repellent layer.
  • Example 1 Composite on an unpolished OSB board
  • OSB wood-based panel unground, gross density approx. 650 kg / m 3 , thickness 15 mm,
  • OSB wood-based panel sanded, gross density approx. 650 kg / m 3 , thickness 15 mm,
  • a wood material board is indicated, which can be a wood fiber or chipboard, an OSB board, a plywood board with a porous or uneven surface, as indicated at 12.
  • a second layer 16 is applied to the uneven and possibly porous surface 12.
  • the second layer is composed of a web-like carrier material, here a fleece, knitted fabric or fabric, as indicated at 16, which is impregnated with a hardenable resin and arranged in the microspheres 18, which expand when heated.
  • Solvent is also contained in a proportion of not more than 40% by weight.
  • Such a composite is disclosed in EP 0 647 182 B1.
  • a third layer 20 is applied to the second layer 14, for example for decorative purposes, for optical reasons or the like. All three layers 10, 14 and 20 are connected to one another in one operation by the action of heat and possibly by pressure. The partially cured resin hardens and the microspheres 18 expand. In this way, a composite panel with the desired surface of predetermined thickness is obtained. As can be seen, the thickness can be varied within limits and, of course, can not be less than the maximum thickness of the wood-based panel 10. The thickness is limited at the top by the mechanical property of the second layer 14.
  • the third layer 20 is not necessary, but rather can Composite panels can also be used with first and second layers. It is also possible to apply the second layer 14 on both sides of the wood-based panel 10.
  • the second layer 16 has a maximum thickness of 6 mm.
