Definitions
- isocyanate As a binder for board products and the resulting advantages and disadvantages are described in the special print "Isocyanate as a binder for particle board" by Dr. G. Loew, Ing. H.I. Sachs, Bayer AG from 1977 on page 479. This shows that polyisocyanates adhere to metals under pressure and heat.
- the solution to this problem is the
- a process for the production of multilayer sheet materials of an isocyanate-mixed mass from wood chips, wood fibers or from woody raw materials is known from AT-PS 270,189. Furthermore, it is known from this publication to use a mixture of isocyanate and urea, melamine and phenol formaldehyde resin glue as the binder or, for example, to bind the chips in the top layer with melamine resin and the chips in the middle layer with pure isocyanate solution or vice versa. The use of a mixture of the abovementioned binders results in a greatly increased moisture resistance and a considerable reduction in swelling when the plate products are exposed to moisture.
- US Pat. No. 5,779,955 discloses a method for producing plate materials, in which par- of vegetable products with isocyanate as a binder and water.
- the base is covered with a liquid release agent before the mixture is spread. After the spreading process, a release agent is also applied to the top of the deposited mixture. The molded body is then hot-pressed.
- the object of the present invention is to provide a process for the production of multi-layered plate-shaped products which can be used depending on the availability of raw materials and which avoids the problems which arise in the prior art in connection with chips insulated with isocyanate.
- the present invention makes it possible to produce a plate-shaped product which consists of a different raw material composition and binders in the middle layer and the top layers.
- This plate-shaped product referred to below as the mixing plate, enables manufacturers who produce chipboard from wood chips in particular to use the available raw material from annual plants as an additional raw material.
- the existing material preparation can be retrofitted or an additional straw preparation line can be added.
- a processing plant to be constructed in this way essentially consists of a single or multi-stage comminution process, dryer, sifter, sieving station and a gluing system suitable for straw.
- the cover layers of the plate-shaped product according to the invention consist of wood chips which are glued with amino and / or phenolic plastics. This avoids the problem of adhering isocyanate-glued chips to the surface of the board when pressing. No additional release agents or release layers are required in the process according to the invention, so that additional costs are avoided.
- the mixing plate according to the invention with wood chips glued to phenol and / or aminoplasts in the cover layers and with isocyanate-glued straw or straw-wood mixtures in the middle layer has sufficient cold stickiness of the scattered molding and good edge stability. This considerably simplifies the manufacturing process. This sufficient cold stickiness, which is not achieved with purely isocyanate-glued straw or wood chips, creates a stable, multi-layered molding which can be more effectively pre-compacted due to the existing cold stickiness and without damaging the previously achieved top layer quality via the individual transfer areas in the molding strand Press inlet can be transported.
- the middle layer material wood is glued with amino and / or phenolic resins and the middle layer material from lignocellulosic annual plants is glued with isocyanate or mixtures of isocyanate and amino / phenolic resins.
- isocyanate as a binder leads to a cost reduction.
- FIG. 1 the method for producing a three-layer chipboard is shown schematically.
- the raw material is first processed. Both lignocellulosic annual plants and wood or other wood-based raw materials are used as the raw material.
- Annual lignocellulosic plants include, for example, cereal straw, rice straw, hemp, soybean straw.
- raw straw and wood are used as raw materials, which are processed independently of one another.
- the grain straw is first processed in a multi-stage comminution process 1.
- the shredded grain straw is then dried in a dryer 2 to a final moisture of about 2 to 5%.
- the dried straw is separated into the coarse material 4, middle layer material 5 and dust 6 fractions.
- the coarse material is returned to the shredding process, and the dust 6 is fed to a combustion system 7.
- the middle layer material CL grain straw 5 is fed to a first gluing station 8.
- the raw material wood is processed at the same time.
- the previously shredded wood chips are also dried in a dryer and then separated into fractions in a sieving station.
- the processing of the raw material wood is not shown in the schematic representation according to FIG. 1, since it is known.
- the middle layer material CL wood 9 fraction is then fed to a second gluing station 10.
- the middle layer material CL grain straw and the middle layer material CL wood could also be fed to a common gluing station.
- the middle layer material CL grain straw 5 is glued with binder.
- Isocyanate is preferably used as the binder.
- water or other additives can be added in addition to the binder.
- isocyanate in emulsified form to the gluing station.
- the middle layer material CL wood 9 is glued with binder.
- Isocyanate is preferably used as the binder.
- water or other additives can also be added in addition to the binder.
- Different binders could also be used in the first and second gluing stations 8, 10.
- the middle layer material wood could be glued in the second gluing station 10 with emulsified isocyanate and the middle layer material cereal straw could be glued with non-emulsified isocyanate.
- the middle layer material of straw is glued with isocyanate and in the second gluing station 10 the middle layer material wood is glued with amino and / or phenolic plastics.
- the middle layer material straw is glued with 1 to 3% isocyanate and about 1 to 3% phenol and the middle layer material wood is glued with amino and / or phenolic plastics.
- the use of powdered phenolic resins in the form of novolak is also conceivable.
- the top layer material SL Holz 11 obtained during wood processing is fed to a third gluing station 12 and glued with aminoplasts as a binder. Instead of aminoplasts, phenolic plastics or mixtures thereof could also be used.
- the middle layer material CL grain straw 5 and CL wood 9 and the top layer material SL wood 11 in the gluing stations 8, 10, 12 are glued with the above-mentioned binders, the glued fractions CL wood 9 and CL grain straw 5 are combined and homogenized by a mixing device 13 .
- the mixing device 13 is preferably arranged directly in front of the molding station 14.
- the homogenized middle layer material CL grain straw / CL wood 5/9 and the top layer material SL wood 11 are fed to a forming station 14.
- the molding station consists of three scattering units 16, 17, 18 arranged one behind the other in the transport direction of the molding belt 15.
- the transport direction is indicated by the arrow 19.
- the first spreading unit 16 is supplied with the glued cover layer material SL wood 11, which is spread as the first layer on the forming belt 15.
- the glued middle layer material CL wood / CL grain straw 5/9, which is sprinkled on the first layer, is fed to the following second spreading unit 17.
- the third spreading unit 18 is also supplied with glued top layer material SL wood 11, which is spread as a third layer on the second layer.
- a three-layer formation is continuously scattered on the for band 15, the outer cover layers consisting of wood chips glued with amino and / or phenolic plastics and the middle layer consisting of wood chips glued with isocyanate and straw straw chips.
- the scattered three-layer molding is then subjected to a continuous Chen pre-press 20, which causes a pre-compression of the molding.
- the molding is hot pressed in a further press 21.
- the further press 21 can be designed as a continuous press or cycle press.
- Middle layer consists of grain straw chips glued with isocyanate.
