Definitions
- OSB Oriented Strand Board
- the present invention relates to a method for the production of OSB wood-based panels according to the preamble of claim 1, to the method produced OSB-wood-based panels according to claim 1 1 and the use of torrequel faced wood strands according to claim 15.
- Coated boards also known as Oriented Strand Board (OSB) boards
- OSB Oriented Strand Board
- strands long chips
- OSB boards originally obtained as waste products of the veneer and plywood industry are increasingly being used in wood and prefabricated house construction, since OSB boards are lightweight and nevertheless fulfill the structural requirements set on construction boards.
- OSB boards are used as building boards and as wall or roof planking or in the floor area.
- the production of OSB boards is carried out in a multi-stage process, wherein initially the chips or strands of debarked roundwood, preferably coniferous wood, are peeled off in the longitudinal direction by rotating blades. In the subsequent drying process, the natural moisture of the beach is reduced at high temperatures.
- the degree of moisture of the strands may vary depending on the adhesive used, and the humidity should be well below 10% in order to avoid breakers during later compression. Depending on the adhesive, wetting may be more favorable on rather wet beaches or on dry beaches.
- as little moisture as possible should be present in the strands during the pressing process, in order to reduce the vapor pressure generated during the pressing process as far as possible, as this could otherwise cause the raw plate to burst.
- the strands are introduced into a gluing device in which the glue or adhesive is applied finely distributed to the chips.
- a gluing device for gluing predominantly PMDI (polymeric diphenylmethane diisocyanate) or MUPF glues (melamine-urea-phenol-formaldehyde) are used.
- the glues can also be mixed in the OSB boards. These glues are used because the OSB boards are often used for structural applications as mentioned above. There must be used moist or moisture-resistant glues.
- the glued strands are scattered in scattering apparatuses alternately along and across the production direction, so that the strands are arranged crosswise in at least three layers (lower cover layer - middle layer - upper cover layer).
- the scattering direction of the lower and upper cover layer is the same, but deviate from the scattering direction of the middle layer.
- the strands used in the top and middle layers differ from each other.
- the strands used in the outer layers are flat and the strands used in the middle layer are less flat up to span-shaped.
- two strands of material are used in the manufacture of the OSB boards: one with flat strands for the later cover layers and one with "chips" for the middle layer Accordingly, the strands in the middle layer can be qualitatively inferior because the flexural strength is essentially due to the cover layers Therefore, fines produced during machining can also be used in the middle layer of OSB boards, after which the strands are spread continuously under high pressure and high temperature, eg from 200 to 250 ° C.
- OSB boards are enjoying increasing popularity and diverse applications, for example as a construction element in house construction or as formwork in concrete construction.
- the inherent hygroscopic properties of wood-based materials have a detrimental effect in some applications.
- Volatile organic compounds also called VOCs, include volatile organic compounds that readily evaporate or are already present as gas at lower temperatures, such as room temperature.
- the volatile organic compounds VOC are either already present in the wood material and are released during workup from this or they are formed according to the current state of knowledge by the degradation of unsaturated fatty acids, which in turn are decomposition products of wood.
- Typical conversion products that occur during processing for example, pentanal and hexanal, but also octanal, octenal or 1 -heptenal.
- softwoods from which predominantly OSB boards are produced contain large amounts of resin and fats leading to the formation of volatile organic terpene compounds and aldehydes.
- VOCs and aldehydes, such as formaldehyde can also be formed or released when certain adhesives are used for the production of wood-based materials.
- the emission of ingredients in OSB boards is critical mainly because this material is predominantly used uncoated. This allows the ingredients to exude unhindered.
- the OSB boards are often used for cladding / paneling of large areas, which usually results in a high space loading (m 2 OSB / m 3 room air). This leads in addition to a concentration of certain substances in the room air.
- various approaches have been described in the past. It is apparent from EP 2 615 126 B1 that a reduction of the VOC emission in OSB plates can be effected by the use of nanoparticles modified with silane compounds. However, the use of such nanoparticles in OSB boards is associated with relatively high costs.
- the invention is now based on the technical object to improve the known per se method for the production of OSB material boards to produce OSB material plates with a significantly reduced emission of volatile organic compounds (VOCs) and with improved swelling values simply and safely. If possible, the manufacturing process should be changed as little as possible and the cost do not rise disproportionately. Furthermore, the solution should include the greatest possible flexibility. Finally, environmental aspects should also be considered, ie the solution should not cause additional energy consumption or generate additional waste.
- OSB wood-based panels in particular OSB wood-based panels having reduced emission of volatile organic compounds (VOCs)
- VOCs volatile organic compounds
- the present method enables the production of OSB wood-based panels using torrefied wooden strands which are introduced into a known manufacturing process in addition to or as an alternative to untreated wood strands.
- An OSB wood-based panel produced by the method according to the invention comprising torrefied wood has a reduced emission of volatile organic compounds, in particular of terpenes, organic acids such as acetic acid and aldehydes.
- OSB wood-based panels By providing the present method, there are several advantages.
- a simple production of OSB wood-based panels is possible without substantially influencing the usual process chain without the classical drying process with significantly reduced emission of volatile organic compounds from the OSB.
- the produced OSB wood-based panels also have a significantly lower swelling and higher dimensional stability.
- torrefied beaches which have a very low humidity, simple products are produced, which are produced by the addition of aqueous formulations, with an adjustment of the water balance is possible.
- Torrefaction is a thermochemical treatment process in which the material to be torrefied is heated in an oxygen-reduced or oxygen-free gas atmosphere at atmospheric pressure.
- Torrefied material is hydrophobic and therefore less susceptible to ambient humidity, so that the risk of rotting torrefected material is extremely low.
- the tanning step of the wood strands may be provided in various ways in the present process.
- At least a portion of the wood strands used to make the OSB boards are dried prior to torrefying, i. in this case dried or pre-dried wood strands, e.g. subjected to a degree of moisture of 5 to 15% moisture, preferably 5 to 10% moisture of Torrefiz réelle.
- at least a portion of the wood strands are torrefied with a humidity of 20-50% by weight, i.
- no previous drying of the wooden strands, but the wood strands are fed without further pretreatment after chipping the Torrefiz istsvorraum.

- the torrefaction of wet wood strands is advantageous because the drying step is saved.
- torrefined wood strands or a mixture of torrefied wood strands and untreated (ie non-torrefied) wood strands are used as the middle layer and / or top layer of the OSB material board. Accordingly, in one variant, a complete substitution of the wood strands is possible, the torrequel faced wood strands are used only in the middle layer, only in one or both cover layers or in all layers. In this variant, the use of a dryer is eliminated.
- torrefied wooden strands In another variant it is possible to form only the middle layer of torrefied wooden strands and to use dried and non-torrefied wooden strands for one or both cover layers. Since torrefected strands have a brown color, it may be advantageous to use torrefied strands only in the middle layer.

- the mixture may comprise between 10 and 50% by weight, preferably between 20 and 30% by weight of untreated or non-torrefied wood strands and between 50 and 90% by weight, preferably between 70 and 80% by weight, of torrefied wood strands.
- the step of Torrefizierens the wood strands can be performed separately from the manufacturing process of OSB wood-based panels.
- the torrefaction step occurs outside the overall process or process line.
- the wood strands are thereby discharged from the manufacturing process and introduced into the torrefying apparatus (e.g., torrefying reactor).
- the Torrefiz convinced wood strands may, after an intermediate storage, for example. be returned to the conventional manufacturing process immediately before gluing. This allows a high flexibility in the manufacturing process.
