Definitions

  • Plate-shaped molded element based on natural fibers and process for its
  • the present invention relates to a method for producing plate-shaped shaped elements based on natural fibers, natural fibers being mixed with binders, the mixture being applied to a molding station, optionally shaped and finally bound.
  • the invention further relates to plate-shaped shaped elements according to the method.
  • the present invention is based on the object of specifying plate-shaped elements and methods for their production which can be produced in a simple manner with little economic outlay and more flexibly and with exact quality expectations than conventional production methods.
  • mats or plates of the generic type should also be able to be produced more easily and with a lower bulk density, that is to say more flexibly and at the same time saving potential due to reduced material requirements.
  • the binder is admixed in the form of body elements which form binders at least partially after activation.
  • the invention now makes it possible on the one hand to prepare the natural fibers to be deployed, and on the other hand to dry body elements which form binders after activation.
  • Both, i.e. natural fibers and body elements can be mechanically mixed, mechanically applied, for example by scattering, easily formed and finally bound.
  • a mechanical method is also proposed for the shaping, for example stripping, pressing and the same.
  • the binding of the body elements is activated to bind the plate.
  • the activation takes place by means of hot air.
  • the applied mixture can be steamed before the hot air treatment, resulting in a higher strength of the mats or panels.
  • the shaped element is cooled, in particular by exposure to cold air.
  • Natural fibers can be cellulose fibers, for example also made from waste paper processing, wood fibers or even wood chips, mineral wool or other vegetable fibers and the like. Almost any mix can be created.
  • the body elements can advantageously also be fibrous, but flakes and similar body shapes are also conceivable.
  • "After activation form binder" in the sense of the invention includes the release of binders adhered to body elements, the melting of the body elements as a whole or the formation of multicomponent binders in that the body elements are multicomponent fibers. So-called organic fibers are known, for example, hot-melt adhesive fibers and the like, which can be used. What is essential in the context of the invention is the use of crosslinking binders, for which copolymers or polyethylene can be used, which can be applied, for example, to polymer supports, in the form of fibers, flakes or the like. Due to the hot air activation, the copolymers or polyethylene sheaths melt and cross-link both with the polymer carriers and with each other, whereby the good but flexible bond of the mats or panels is achieved. The crosslinking process is completed by subsequent cooling.
  • a particular advantage of the invention results from the fact that the natural fibers and the body elements can be mixed very easily in a simple manner, so that it can be assumed that the shaped element has a very good bond over the total volume.
  • the molding mixtures can be produced dry, so that it is possible to mix, for example store or transport. This makes the manufacturing process considerably more flexible because it no longer has to be processed at the mixing site. The storage of the individual components and the mixture of the components are simplified.
  • the mixture as a whole can be handled more easily, so that complex spreading devices and the like can be dispensed with.
  • Simple mechanical spreading heads and the like known per se are sufficient.
  • the shape is also very simple and the activation, for example by blowing hot air through, is much more economical and simple compared to heating presses.
  • the advantages result from the mixing of the natural fibers on the one hand with synthetic fibers to provide the binder on the other hand.
  • the use of the crosslinking binder makes the boards flexible overall and has only a low bulk density. This results in an economic producibility of the plates according to the invention, since less material is required for the same volume.
  • the handling of the mats or panels is considerably improved, since they no longer tend to break and have the flexibility required for handling. They can be pressed into gaps, are compressible and can even be thrown during transport and do not tend to break off the edges when one-sided force is applied. Correspondingly higher strengths can be achieved by simple pre-steaming before hot air activation.
  • Fig. 1 is a block diagram for an embodiment of a process flow of the method according to the invention.
  • short fibers 1 for example paper fiber, wood fibers, cellulose fibers or the like
  • long fibers 2 for example jute, sisal and the like
  • the binder body elements 3 are mixed with one another.
  • the binder body elements can be thread-like or fiber-shaped, flake-shaped or in some other way.
  • corresponding carrier elements have a jacket of crosslinking plastics, for example polymer carriers with a copolymer or polyethylene jacket.
  • the basic material consisting of natural fibers, which can be composed of short fibers and long fibers, optionally a fire protection agent 2, for. B. borax, and a binder 3, z. B. Biko fibers are mixed together in station 4, and then mechanically applied at 5 and formed into a mat.
  • These processes take place in a manner known per se in a purely mechanical way, the shaping being able to take place, for example, by wiping and the like.
  • the shaped mat is first damped in step 6 to achieve high strength. This is followed in step 7 by pressing and hot air activation, in which the moisture introduced by steaming is dried out at the same time. If crosslinking binders have been used, a cooling step 8 then takes place. Finally, in step 9 the mat or plate is made up, that is to say cut open and the like. Finally, the plates formatted in this way are packed in step 10.
