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-based materials made of chipboard or fiber material are used, for example, in the construction furniture and furnishing industry.
- fiber insulation boards HFD
- HH 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 produced with synthetic resin adhesive under the supply of heat in the flat pressing process. The chips are aligned in the direction of the plate plane.
- the area of use of the wood fiber boards is similar to that of 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.
- wood fibers or lignocellulose-containing fiber material are used for the production of wood fiber boards or flat pressed boards. By means of heat, moisture and mechanical pressure forces in fiberizing plants, the wood chips are processed for a production of the plates.
- wood and wood fiber boards only wood is used as the starting material. The resources of this natural product are limited and also for reasons of nature conservation it is desirable to be able to use alternative raw materials. In addition, it is also interesting for cost reasons to look for alternatives for the production of corresponding wood or wood fiber boards.
- the DE 10330756 A1 discloses a process for the production of a solid for the production of molded parts, in which a binder is added to the pulp and pressed into a molded part under the application of heat.
- the disclosed method is characterized in that a particle or fiber mat of a first group of particles or fibers is admixed with a proportion of plastic particles and / or plastic fibers whose particle size corresponds approximately to the particle size of the particles or fibers of the first group.
- the plastic particles and / or fibers are obtained by crushing and / or fibring of pure or mixed plastic agglomerates in a disc refiner, whereby the disc refiner is supplied with water during the comminution process.
- the DE 10 2004 008 827 A1 discloses a plate, a molding and a cover layer of a wood material, wherein a wood material is provided, which is ground or contains shredded agglomerate of plastics from the waste disposal. According to the disclosure of DE 10 2004 008 827 A1 in the plastic particles used pure plastics, mixed and / or film plastics from collection systems or pure or mixed plastics from recycling systems.
- the US 2006/0121261 A1 discloses a fiberboard wherein synthetic particles or fibers are mixed into the wood fibers or wood flakes. The ingredients are pressed into a plate under heat and some of the wood fibers or flakes are replaced by ground or shredded agglomerates of mixed synthetic waste material. According to the disclosure of US 2006/0121261 A1 If the synthetic waste materials are plastic or plastic mixtures.
- the WO 2008/114103 A1 discloses the admixture of cork to wood raw material for the production of wood fiber boards. Cork is the material of the bark of a cork oak and thus another raw material, which is to be assigned as a special part of a tree the range of wood raw materials.
- the DE 10 2004 011 931 A1 discloses an insulating board made of a wood-material-binder fiber mixture and a method for producing an insulating board, in which the mixture is added to an additive with a thermally stable core and a thermally activatable coating and activated under 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.
- the DE 10 2006 054 204 describes a technology in which pure plastics are used, which are then to be melted, which is to be effected by an extruder. It does not disclose methods dealing with alternative ingredients in the starting material for making a plate.
- the DE 14 53 374 A describes a method for producing composite bodies.
- the base material is compressed by admixing thermoplastic films and the action of pressure and heat. Accordingly, 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.
- the DE 44 10 576 A1 deals with the production of panels, 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, which can be used to produce a wood or wood fiber board, the resulting plate the requirements of the corresponding country-specific standards, for example, according to the German or European EN or DIN is sufficient.
