Definitions
- the invention relates to a method for producing a wood material, in particular a plate-shaped wood material, as well as a wood material produced by the method.
- Wood-based materials in particular plate-shaped wood-based materials such as chipboard, fiberboard and OSB boards, have been established for many years in various areas of furniture and interior design as well as in construction.
- the materials mentioned have in common that they are made of small-sized wood or wood fibers, usually with the addition of a natural or chemical binder, by pressing under elevated pressure and elevated temperature.
- all sawmill by-products such as sawdust, wood chips, chipboard wood, in the recent past also in importance increasingly used wood, in the production of wood-based materials used.
- binders are usually based on formaldehyde resins, in the field of OSB boards also of significant importance those based on isocyanates.
- binders on a natural basis for example on Taninbasis, for certain applications within the wood materials are known.
- EP 1 121 231 and DE 101 16 686 special processes for the pretreatment of the straw particles used here.
- special measures are required which should give the straw particles comparable binding properties to the wood particles.
- the object of the invention is therefore to provide a method and a corresponding wood material, with which the production using husks of oats is simplified.
- the previously derived and indicated object is achieved according to a first teaching of the present invention by a A process for producing a wood material, in particular a plate-shaped wood material, wherein used for at least partial substitution of the wood content selected parts of husks of the oats.
- a wood material in particular a plate-shaped wood material, which is prepared by a method as described above.
- certain parts of husks of the oat can be used in their properties for use as a material for at least partially substituting wood in wood-based materials without a special pre-treatment and without the use of a special binder.
- Oats have no perianth, but the flowers are wrapped in dry-skinned bracts, just the husks.
- the husks of the oats remain on the grains during the harvest of the oats, which is why the husks are preferably separated from them in a separate working step, in particular before the processing of the oat grains.
- the availability of oat husks is constant throughout the year and does not depend on harvest times, where otherwise the total annual volume of raw materials of other annual plants is obtained.
- husks of the oats have a form and extent comparable to the shavings of the middle layer of a chipboard and, after separation from the oat grains, also have a moisture content which is in the range required for the production of chipboard.
