Definitions

  • isocyanate as a binder use.
  • isocyanate as a binder for plate products and the resulting advantages and disadvantages are in the special issue "isocyanate as a binder for particle board ", by Dr. G. Loew, Ing. H. I. Sachs, the Bayer AG of 1977 on page 479 described. It is clear from this that polyisocyanates adhere to metals under pressure and heat. As a solution to this problem is the Use of liquid release agents as well as the use of Papers, veneers, as well as dust or conventionally glued Spandeck layers proposed.
  • a method for producing multilayer board materials an isocyanate-added mass of wood shavings, Wood fibers or from woody raw materials is from the AT-PS 270,189 known. Furthermore, it is known from this document as a binder, a mixture of isocyanate and Urea, melamine and phenolformaldehydharzleim to use or, for example, the chips in the cover layer with melamine resin and the chips of the middle layer with pure isocyanate solution to bind or vice versa.
  • a binder a mixture of isocyanate and Urea, melamine and phenolformaldehydharzleim to use or, for example, the chips in the cover layer with melamine resin and the chips of the middle layer with pure isocyanate solution to bind or vice versa.
  • the object of the present invention is to provide a method for To provide manufacture of multi-layered plate-shaped products, depending on the availability of raw materials can be used and occurring in the prior art Problems associated with isocyanate-coated chips be avoided.
  • the production of a plate-shaped product possible consisting of a different Raw materials composition and binders in the Middle layer and the outer layers consists. Because of this hereinafter referred to as mixing plate plate-shaped product It is manufacturers, in particular chipboard from wood shavings produce, possible, the available raw material from annual plants as additional raw material. In a conventional manufacturing plant of chipboard made of wood chips can the existing material processing converted or to an additional straw preparation line be extended. Such a building Processing plant consists essentially of a or multi-stage comminution process, dryer, sifter, Siebstation and a gluing plant suitable for straw. Depending on the availability of the raw material from annual plants the proportion of raw material from annual plants in proportion to the raw material wood in the middle class varies become.
  • the cover layers of the plate-shaped invention Products consist of wood shavings containing amino and / or Phenolplasten are glued. This will solve the problem of Adherence of isocyanate-coated chips to the plate surface avoided during pressing. In the method according to the invention no additional release agents or release liners are needed so that additional costs are avoided.
  • the mixing plate according to the invention with phenolic and / or aminoplasts glued wood chips in the top layers as well as with isocyanate-glued straw or straw-wood mixtures in the Middle layer has a sufficient cold tack of the scattered Moldings and a good edge stability. hereby the manufacturing process is considerably simplified. By this sufficient cold sticking, the pure isocyanate glued Straw or wood shavings is not achieved, is one stable multilayer molding produced due to allows the existing cold tack more effectively pre-compacted as well as without damaging the previously achieved cover layer quality over the individual transfer areas in the form strand for Transport press entrance.
  • a decreasing proportion of isocyanate as a binder leads to a cost reduction.
  • the inventive method is based on an embodiment, which is shown in Fig. 1, described in more detail.
  • Fig. 1 the method for producing a three-layered Chipboard shown schematically.
  • the raw materials are both lignocellulosic Annual plants as well as wood or others on wood used based raw materials.
  • lignocellulose-containing annual plants examples include Cereal straw, rice straw, hemp, soybean straw.
  • Cereal straw examples include Cereal straw, rice straw, hemp, soybean straw.
  • a three-layer chipboard are used as raw materials Cereal straw and wood used independently be prepared.
  • the grain straw is initially in a multi-stage crushing process 1 processed.
  • the crushed cereal straw is then in a dryer 2 to a final moisture of about 2 to 5% dried.
  • a subsequent sieving station 3 the dried cereal straw into the fractions Grobgut 4, middle layer material 5 and dust 6 separated.
  • the coarse material is returned to the crushing process, the dust 6 is fed to a combustion system 7.
  • the middle layer material CL cereal straw 5 becomes a first gluing station 8 supplied. Regardless of the processing of cereal straw
  • the raw material wood is processed.
  • the previously crushed wood chips are also in one Drier dried and then in a sieving in Fractions separately.
  • the preparation of the raw material wood is not shown in the schematic representation of FIG. 1, since she is known.
  • the fraction middle layer material CL Holz 9 is then sent to a second gluing station 10 supplied.
  • the middle layer material CL could be cereal straw as well the middle layer material CL wood also a common Beleimungsstation be supplied.
  • the middle layer material becomes CL cereal straw 5 glued with binder.
  • Isocyanate is preferably used.
  • the first Gluing station 8 may contain water in addition to the binder or other additives are added.
  • the second gluing station 10 the Middle layer material CL wood 9 glued with binder.
  • Binder is preferably used isocyanate.
  • the second gluing station 10 may also be in addition to the binder water or other additives are added.
  • 10 could also be different Binders are used.
  • Binders are used.
  • Middle layer material wood in the second gluing station 10 glued with emulsified isocyanate and the middle layer material Cereal straw is glued with non-emulsified isocyanate.
  • the middle layer material Cereal straw is glued with isocyanate and in the second Gluing station 10, the middle layer material wood with amino and / or phenolic plastic is glued.
  • the middle layer material Cereal straw with 1 to 3% isocyanate and about 1 to 3% phenol is glued and the middle layer material Wood is glued with amino and / or phenolic resins.
  • the top layer material SL obtained during the wood treatment Wood 11 is fed to a third gluing station 12 and glued with aminoplast as a binder.
  • aminoplasts also phenolic plastics or mixtures thereof could be used become.
  • the middle layer material CL cereal straw 5 and CL wood 9 as well as the cover material SL wood 11 in the Beleimungsstationen 8 10, 12 with the above Binders are glued, are the glued fractions CL Wood 9 and CL cereal straw 5 by a blender 13 brought together and homogenized.
  • the mixing device 13 is immediately in front of the forming station 14 arranged.
