Definitions

  • the invention relates to a method for producing an insulation board from natural fibrous materials with low bulk density.
  • natural fibrous materials or “natural fibers” mean fibers of plant and / or animal origin, for example flax or sheep's wool.
  • the fibrous materials are processed into individual fibers, the individual fibers are wetted with a binder, and the wetted fibers are deposited as a primary nonwoven, whereupon the primary nonwoven is compressed, hardened and processed on the edges and surfaces becomes.
  • the invention avoids the "non-woven" method proposed in the prior art, which works without the addition of binders. It has been surprisingly found that natural fibers of animal or vegetable origin are amenable to wetting with binders r which opens the possibility, instead of directly Dämmvliesen produce insulation boards.
  • bale openers are known from the textile machine sector and can be used here. The preparation is carried out until the fibers are separated as completely as possible. The separated fibers can then be mixed with the binder in an air flow (swirl chamber)
  • the fibers on the surface can be coated particularly easily and completely.
  • the binder is applied to the fibers by means of an immersion bath and dried at temperatures of around 80 degrees Celsius.
  • the fibrous materials particularly if they are sheep's wool, can still be handled like dry wool, i.e. they can be torn, processed into a fleece and subjected to all other treatments which require that the fibers do not stick together.
  • the binder is only activated to bond the fibers in the hardening furnace at a higher temperature, which can be around 150 degrees Celsius.
  • binders based on starch or protein or a curable resin or synthetic resin or a curable resin combination or synthetic resin combination as well as water glass modifications or silicates are suitable in this sense.
  • the thickness and density of the insulation board to be produced can be adjusted, for example, by placing the primary fleece on top of one another in a corresponding number of layers (layers) before compression, for example between rollers or belts.
  • the delivered natural fiber material (here: sheep wool bale) is transferred from a box storage 1 to a conveyor belt 2 with a belt scale 20, the speed of the conveyor belt 2 being adjustable depending on signals emitted by the belt scale 20, so that the quantity of sheep wool can be set is.
  • sheep's wool is roughly broken up between a circulating belt 30 and a plucking roller 32. Then it is fed to a washing system 4.
  • the waste water from the washing system 4 is disposed of directly after a separation of the fat content in a centrifuge 5 via a waste water system 6.
  • the sheep wool cleaned in this way is dried in a drum dryer 7 and then mechanically broken down into individual fibers in a device 8 for the fine dissolution of the fibers between plucking roller pairs 80, 82 or 84, 86.
  • These individual fibers are introduced into a finishing device (coating device) 9 through an opening 90 in the upper region thereof, a fan 92 causing the fibers to be swirled, similarly to a swirl chamber.
  • a fine mist of a binder (here: protein-based) is sprayed onto the surfaces of the fibers by means of a spray device 94, so that these are largely completely wetted by the binder.
  • the wetted individual fibers are drawn off from the device 9 and between a smooth roller 15 and a plucking roller 16 placed on a conveyor belt 17 to form a primary fleece.
  • a system (not shown here), with which the continuously transported primary nonwoven is put on top of one another in several (preselectable) layers, can be connected before the nonwoven is fed to a compression station 10, where it is compressed in the desired manner between rollers 102, 104.
  • the compression station 10 is followed by a hardening furnace 11 in which the binder is dried and / or cured.
  • the thus hardened, dimensionally stable fleece is then processed in a station 12 on the edge side and on the surface, for which purpose trimming and calibration saws are provided.
  • the insulation boards thus finished are stored in a storage device 13.

Abstract

Procédé de fabrication d'un panneau isolant constitué de matières fibreuses naturelles de faible masse volumique apparente, selon lequel les matières fibreuses subissent un traitement de séparation en fibres individuelles qui sont à leur tour imprégnées d'un liant. Les fibres ainsi imprégnées sont déposées sous forme d'un non-tissé primaire qui est ensuite cuit et dont les bords et les surfaces sont façonnées.
