Definitions

  • the present invention relates to a composition for wood and wood fiber boards, wood or wood fiber boards themselves and a method for producing wood or wood fiber boards.
  • Wood materials from chip or fiber material are used for example in the construction furniture and furnishing industry.
  • fiber insulation boards HFD
  • HDH hardboard
  • MDF boards MDF boards. These are made of finely shredded, mainly bark-free softwood and by a gentle compression in the longitudinal and transverse direction. The edges are smooth and firm and can be profiled without special edge banding.
  • chipboard or flat press plates which consist of wood chips of various sizes, which are made with synthetic resin adhesive with the supply of heat in the flat pressing process. The chips are aligned in the direction of the plate plane.
  • wood fiber boards are similar to the chipboard, however, can be profiled by the fine, almost homogeneous structure of the wood fiber board, the edges and surfaces and then painted. The need for gluing, as would be the case with flat-pressed plates, is eliminated.
  • DE 10 2004 011 931 Al discloses an insulating board of a wood-material-binder fiber mixture and a method for producing an insulating board, wherein the mixture is added to an additive with a thermally stable core and a thermally activatable coating and activated with heat ,
  • the main idea of this disclosure is the ability to selectively achieve a thermal activation for bonding the ingredients.
  • the use of alternative raw materials or raw material compositions for the manufacture of wood or fiberboard does not disclose this document.
  • DE 103 54 394 A1 discloses a special binder and its use for bonding wood-based materials and / or fibrous materials.
  • the subject of this document is directed to the compounding of the raw materials of such plates and is not concerned with alternative additives to be used in the manufacture of wood or fiberboard.
  • DE 14 53 374 A describes a process for the production of composite bodies.
  • the base material is compressed by admixing thermoplastic films and the action of pressure and heat.
  • this reference is concerned with the compounding of the raw materials of a board made using pressure and heat, but not with the use of alternative combinations of raw materials.
  • DE 44 10 576 Al is concerned with the production of plates, which consists of a mixture of plastic, wood, semi-wood and recycled material. In order to produce such plates, the plastic components must be fused and pressed under special process conditions.
  • a disadvantage of this method is that the required parameters in terms of pressure and temperature can not be achieved on conventional systems in use, without having to make major and costly adjustments to the equipment.
  • the object of the present invention is therefore to provide a composition for the production of a wood or wood fiber board available, which can be used to produce a wood or wood fiber board, the resulting plate to the requirements of the corresponding country-specific standards, for example German or European EN or DIN is sufficient. Furthermore, a manufacturing method using the composition and the wood or wood fiber boards are the subject of the invention.
  • a composition comprising a pulp, a binder, a curing accelerator and a paraffin emulsion, wherein the pulp contains at least 5% wood-foreign raw materials provided.
  • This composition is suitable for the production of wood or wood fiber boards, which are not only made entirely of wood.
  • the foreign substances are solids, in particular also mixtures. various solids.
  • the solids are organic or inorganic solids, wherein the organic substances may be synthetically produced, such as plastics or may be decomposable as biological substances such. As proteins, sugars or fats, oils or natural fibers.
  • wood extraneous raw materials as part of the pulp is the wood extraneous raw materials as part of the pulp to a mixture consisting of 0 - 40% inorganic portions, 5 - 100% synthetic organic content and / or 0 - 95% decomposable organic fractions, wherein each of the proportions used to add 100% to the wood extraneous raw material.
  • a composition may additionally contain urea and / or lignin sulphonates and the binder may be urea-formaldehyde, maleimine or phenolic resin or a combination thereof.
  • Another object of the invention is a wood or wood fiber board, consisting of a compressed composition containing at least 5% wood foreign substances.
  • a method for producing a wood or wood fiber board comprising:
  • urea-formaldehyde, melamine or phenolic resin or a combination thereof may be used as the binder, the raw material mixture being based on an acidic pH when urea-formaldehyde resin is used - Value, preferably between 5 to 5.8, is set.
  • the use of other binders or adhesives of the invention is also included.
  • wood extraneous raw materials can be used as part of the pulp, consisting of a mixture of 0 - 40% inorganic portions, 5 - 100% synthetic organic content and / or 0 - 95% decomposable organic content exist, with the proportions used each add up to 100% wood extraneous raw material.
  • Fig. 2 wood or wood fiber board consisting of at least 5% wood foreign raw material.
  • Figure 1 shows the sequence of a method for producing a wood or wood fiber board according to the invention.
  • a wood raw material 10 for example chips of a softwood
  • a wood-external raw material 20 are used for producing a composition for the pulp 20.
  • the mixture is then defibred 40 and the resulting pulp dried 40.
  • the compression of the pulp takes place at preferably 150 - 250 0 C and a pressing time of 15 - 25 s / mm 2 .
  • the plates are trimmed and ground to a uniform thickness.
  • FIG. 2 shows a part of a wood or wood fiber board 21 which has been produced using at least 5% of non-wood raw material and wood raw material.
  • MDF medium-density fiberboard
  • an MDF board which consists exclusively of pine wood chips and an MDF board, which consists of pine wood chips and a raw material with non-woody ingredients in a mixing ratio of 80% pine wood pulp and 20% wood extraneous raw material ,
  • the data refer to the dry matter.
  • a UF resin 350 BASF was additionally used as binder.
  • thermomechanical process From the pine wood chips or pine wood chips / raw material mixture fibers were prepared by the thermomechanical process (TMP process).
  • TMP process thermomechanical process
  • the digestion of the raw materials took place in a laboratory refiner plant with a cooker and pipe dryers.
  • the digestion temperature was at 150 0 C at 5.0 bar and the digestion time was 5 minutes.
  • the fibers were followed in the tube drier by a drying in the drying oven at 65 0 C to a fiber moisture content of about 2% dried.
  • the dried pulps were glued in a blender as follows:
  • the binder used was a urea-formaldehyde resin (UF resin K350), with a binder consumption of 15% (solid / dry pulp).
  • the hardening accelerator was ammonium sulfate (2% solid hardener / solid resin).
  • the respective material was hot-pressed into plates.
  • single-layer plates were produced with a plate thickness of 16 mm and a target density of 750 kg / m 3 .
  • the pressing temperature was 200 0 C and the pressing time 15 s / mm plate thickness.
  • the exemplary embodiment shows that an MDF board can be produced which complies with the required standards but is not 100% made of wood.
  • the present invention provides an alternative to entirely wood panels, thereby conserving natural resources and providing a means for using other additives.
  • the non-wood material may have inorganic components such as salts, glass, metal, ceramics, etc. and / or synthetic organic substances such as plastics and / or decomposable organic substances such as natural fibers, Fats, oils, sugars or proteins.
  • inorganic components such as salts, glass, metal, ceramics, etc.
  • synthetic organic substances such as plastics and / or decomposable organic substances such as natural fibers, Fats, oils, sugars or proteins.
  • a mixed input stream may be used as a wood substitute in a standard MDF or particle board process. This has hitherto not been possible, since in this process, due to the mere mixing of wood with wood substitutes, subsequent bonding and pressing, just no corresponding stability and durability could be achieved, as shown in the above example.
  • the starting material is pre-treated in a process of this invention such that it can be used as a wood substitute, leaving all common parameters in known standard processes. This means that the previously disclosed method can be applied to machines that are already in use and there is no need to make any special adjustment to reach particular pressures or temperatures.
  • non-wood raw material 21 Plate made of pressed fiber material with 5% non-wood raw material
