Definitions

  • the invention relates to a method for producing hardboard, in which the hardboard is subjected to an impregnation treatment after it has been produced.
  • hardboard The impregnation of hardboard is known per se. By using an impregnation process, hardboard can be refined into a wide variety of products with different surface properties.
  • a disadvantage of the known hardboard is that it normally exhibits a fire behavior that corresponds to fire class B 2 according to DIN 4102.
  • the known hardboard is therefore normally flammable.
  • the finished raw plates are exposed to a negative pressure in a pressure vessel, the plates being soaked while maintaining the negative pressure after the negative pressure has been applied.
  • a vacuum of 85% is generated in the pressure vessel. This negative pressure is maintained for about 2 minutes to 2 hours. An evacuation time of 10 minutes is preferred.
  • the salt must meet DIN standard 68 800, which relates to resistance to fungal attack.
  • the impregnation can advantageously be carried out in the boiler pressure process.
  • raw plates are used which show a low swelling behavior from the outset, so that the impregnation of the raw plates presents no difficulties.
  • the invention is accordingly based on the object of providing a method of the type mentioned at the outset, in which it is possible to produce hardboard which is flame-retardant and which achieves fire class B1 according to DIN 4102.
  • the hardboard consists of resin-bonded pressed wood fibers and are provided with a paraffin emulsion and / or other water repellents and that the plates are soaked with an aqueous salt solution so that after drying 100 to 300 kg of salt mixture included per m3.
  • a salt mixture based on phosphate-borate is particularly suitable as the impregnation salt.
  • ammonium phosphates and borates but also urea, melamine or guanyl urea phosphates can be used.
  • the salt mixtures can also contain fluorides, guanidine sulfonates and chromium, copper and / or zinc salts.
  • the plates are then removed from the pressure vessel and subjected to drying at about 80 ° C.
  • This drying can take place in a drying cabinet or in a vacuum dryer at a vacuum of about 20%.
  • the hardboard produced in this way can be painted, coated and / or laminated.
  • the method according to the invention is particularly suitable for hardboard with a thickness of about 2 to 6 mm, since the continuous impregnation is guaranteed for boards of this thickness.
  • the method according to the invention can also be applied to medium-hard wood fiber boards with a bulk density (board weight) of about 350 kg / m3 to 800 kg / m3.
  • porous wood fiber boards with a bulk density (board weight) of about 200 kg / m3 to about 400 kg / m3 is also possible.
  • a trough is provided in a device for carrying out the method according to the invention, in which the wood fiber raw boards are placed one above the other with the interposition of spacers, rods, wires or the like.
  • a tub on the one hand facilitates loading and removal from the pressure vessel and on the other hand saves liquid, since only the tub and not the entire pressure vessel has to be filled with liquid during the process.
  • the tub in particular also facilitates the removal of the liquid used, which is fed to a storage container and consequently can be reused in the manner described.
