Definitions

  • the present invention relates to a process for the production and simultaneous decorative coating of a wood-based panel, in particular in the form of a wood-plastic composite material according to claim 1.
  • wood-based panels e.g. in the form of wood fiber boards in various configurations for use as a laminate floor or for cladding walls or in the manufacture of furniture has long been known.
  • wood fiber boards in the form of medium density wood fiber boards (MDF boards) or high density wood fiber boards (HDF boards) are used, which are obtained by pressing corresponding wood fibers or chips with a thermosetting plastic resin as a binder.
  • a particular problem with the use of said wood fiber boards is the sensitivity of the wood fibers or wood chips used to high humidity and direct water contact. While this problem can be dealt with relatively easily in the case of furniture or interior products by means of constructional or technological measures, in the case of floor coverings, e.g. Floor laminates based on wood or wood-based materials are often much more problematic.
  • Floor coverings based on wood or wood-based panels such as laminate flooring or parquet quickly react to water contact with swelling and / or dimensional changes. This is caused, inter alia, by the effects of water-based care products, some of which are used very frequently and very intensively. Also, high humidity can trigger comparable processes.
  • the flooring is typically also in direct contact with the building parts such as concrete floors / screed or walls, which may also carry moisture in the flooring.

  • the width of the plates is usually in a range of less than one meter due to the manufacturing process in an extruder.
  • the productivity per hour is in a low single-digit square meter range, so that the combination of low productivity and limited board size causes relatively high costs of the WPC boards so produced.
  • the products are only produced in the continuous width in the appropriate widths and separated to the required length.
  • the agglomerates are homogeneously scattered on a belt, pressed in a double-belt press to a plate and cooled.
