Definitions
- the invention relates to a wood-based panel having at least three layers of a wood material whose at least one middle layer consists of a mixture of wood material and a foamed plastic, and to a method for producing a wood-based panel.
- Such a wood-based panel is known for example from DE 20 2006 020 503 Ul, to which reference is made in full.
- the middle layer contains a light weight
- Wood material with 30 to 95 weight percent wood particles which have a mean density of 0.4 - 0.85 g / cm 3 . Based on the light wood material up to 20 percent by weight of polystyrene and / or styrene copolymer are included as a filler, wherein the filler has a bulk density of 10 to 100 kg / m 3 . In addition, 2.5 to 50 percent by weight of binder are included, and the middle
- Density of the light wood material is less than 600 kg / m 3 .
- the mechanical-technological parameters decrease, so that such panels can not be used with an average density of 500 kg / m 3 .
- Wood-based panels are understood to mean plate-shaped plywood, chipboards, such as flat-pressed sheets, extruded sheets, OSB sheets or sheet metal sheets.
- BESTATIGUNGSKOPIE lerplatten wood fiber boards, such.
- MDF or HDF fibers and other wood-based panels such as plywood panels, molded wood moldings or laminated plywood.
- stable plates are relatively heavy due to their thickness, which can lead to transport problems especially for self-builders.
- EP 1 561 554 B1 discloses a wood-based panel in which a layer of foamed plastic is introduced between two layers of wood material, and the plastic layer forms the core of the panel.
- the top and bottom of the wood-based panel is made of wood fibers or
- Wood shavings In this wood-based panel, the core is crosslinked with wood fibers or wood shavings. In order to achieve an improved connection of the foamed plastic with the wood materials, it can be provided to sprinkle a mixture of wood materials and plastic granules between the two outer layers of wood material.
- JP 2002-338373 A1 describes a method of producing a wood cement board having improved heat-insulating properties.
- a mixture of wood raw material and cement is introduced into a mold.
- Foamed resin beads are sprinkled on this first layer.
- a layer of wood raw material and cement is applied to this layer again.
- This precursor is pressed in a press so that the foamed resin remains in the middle layer of the press blank. Subsequently, the press blank is exposed in a steam press high-temperature steam, so that the foamed resin particles cure.
- DE 1 185 806 B describes a method for producing a sandwich panel with a core layer of foamed plastic and support layers of a fiber cement composition which can be applied on both sides, wherein the support layers also consist of a mixture of cement and wood wool can exist.
- US 5,554,429 A describes a wood-based panel having a core layer of at least one OSB board, which has been produced with an intumescent adhesive and provided with at least one cover layer of another OSB board, wherein the cover layer is bonded to a surface of the core layer.
- the foaming adhesive may be, for example, a polyurethane adhesive.
- the plate is produced in a hot press at a pressure of about 1 to 2 MPa and a temperature in a range between 150 and 200 ° C, wherein the foaming of the foam takes place in the press.
- DE 42 26 988 A1 describes a molded part of natural fibers impregnated with a foamed synthetic resin, which consists of two outer layers of natural fibers and of a middle layer enclosed by the outer layers.
- the middle layer is at least partially formed by a foamed synthetic resin.
- the middle layer can receive wood chips, wood chips, wood bark and needles of conifers as filler.
- the blend of natural fibers for the outer layers and resin for the middle layer is placed in a heated mold. After closing the heated mold, the temperature of the resin is brought to, for example 60 ° C, whereby the resin foams and passes through the fiber layers.
- EP 1 253 257 A1 describes a process for the production of a surface element and a wood-based material board with a layer of foamed polystyrene between two wood-based panels. Two finished wood-based panels are then connected with insulating panels via an adhesive.
- the wood-based panel described above is to be improved to the effect that good mechanical / technical parameters are maintained in a further reduction of the bulk density and the emission of aldehydes is reduced.
- a generic wood-based panel is characterized. - A -
- the at least one middle layer additionally comprises at least one foamed natural material.
- the natural material for example, corn, rice, wheat or a mixture of these come into question.
- the natural material has the advantage that it has a higher strength compared to conventional materials, but it has a lower density than the wood fibers or wood chips.
- a mean apparent density of less than 500 kg / m 3 can be achieved, wherein the bulk density of the outer layers is greater than 500 kg / m 3 .
- the bulk density of the middle layer is less than 450 kg / 3 and the deviation of the average bulk density does not exceed plus / minus 50 kg / m 3 .
- the middle layer may have fibrous or filamentary components. These ingredients are preferably made of natural
- the fibrous or filamentary components may also consist of plastic, in particular carbon, PE, PP, PET, glass fibers or two components.
- cover layer Conventional types of wood are preferably used for the cover layer.
- middle layer are preferably woods with low bulk density, such as. Poplar or alder.
- other suitable types of wood can be used.
- At least the middle layer may comprise additional plastic fillers, preferably based on polyurethane foams and / or polystyrene foams.
- the middle layer may additionally contain latent heat storage.
- latent heat storage For example, plastic capsules with a core of pure wax, such as those marketed by BASF under the name "Micronal PCM.” If the room temperature rises above the switching temperature of 23 or 26 degrees Celsius as defined in the production of the microscopically small plastic capsules, liquefaction takes place As the wax inside the microcapsules absorbs the excess heat of the room, when the temperature drops, the wax solidifies and the capsules release their heat back to the room, and the periodic succession of melting and solidification is tempered by differences in temperature Day and night, the latent heat storage systems help to absorb temperature peaks during the day.
- the provided with adhesive wood fibers, wood chips or wood strands are strewn together with the fillers and the other light components to layers and then connected together in a hot pressing process under pressure.
- Suitable adhesives are UF,
- MUF MUF
- MUPF PF
- PF TF
- Wood-based panel in which each individual layer is sprinkled with a lath-wetted wood material, characterized in that the at least one middle layer foamable natural products, especially corn, rice or wheat are added and the scattered layers are pressed into a plate desired thickness , wherein the natural products foam during the pressing.
- the at least one middle layer is preferably also admixed with plastic fillers based on polyurethane foams or polystyrene foams, which foam in addition to the natural products during the pressing.
- the foaming of the natural products takes place by bursting, whereby the voids between the wood fibers or wood chips are filled.
- the foamed natural products additionally act as an aldehyde catcher. It is particularly advantageous that this effect is long-lasting due to the fixed integration into the plate matrix.
- Figure 1 is a plan view of the scattered middle layer of a wood-based panel to the line of symmetry;
- Figure 2 shows the detail enlargement II of Figure 1;
- Figure 3 shows the raw density distribution of the wood-based panel over its cross section.
- a wood-based panel is produced by scattering individual layers into a cake and then pressing the cake to the desired board thickness.
- the process of gluing the wood fibers or shavings, spreading and pressing has long been known.
- FIG. 1 shows a part of the at least one middle layer 1 of a wood-based panel, which is scattered symmetrically with respect to the axis of symmetry A.
- This middle layer 1 consists of wood chips or wood fibers 2, conventional fillers 3, such as polystyrene, polyisocyanate or polyol and a blowing agent.
- the layer 1 contains foamable natural substances 4, such as corn, rice or wheat.
- filamentary reinforcing fibers 5 are provided.
- FIG. 3 shows the gross density profile of the wood-based panel according to the invention over its thickness (thickness). It can be seen that the cover layers 6 have a substantially greater density than the middle layer 1.
