Definitions

  • the invention relates to a method for introducing foam material in hollow chamber profiles, in particular window or door hollow chamber profiles, wherein initially by means of an extrusion process, the shaping of the at least one hollow chamber having hollow chamber profile.
  • DE 100 31 568 A1 discloses a method for foaming a hollow chamber profile, in which a polyurethane reaction mixture is first applied to a support material and drawn into the hollow chamber to be expanded before the start of the foaming triggered by the chemical reaction.
  • FIG. 7 shows the time evolution of the thermal conductivity in W / mK of an appropriate foaming with two different thicknesses (40 mm and 80 mm). It can be seen that the thermal conductivity in both cases already after about 3 years l increased by about 15%. This increase can be explained by the fact that the cell gas exchanges with air over time, which has poorer thermal insulation properties compared to the cell gas. Due to the described effect, the thermal conductivity of the entire insulation profile increases and the heat transfer through the hollow chamber profile increases.
  • the invention has for its object to provide a method for introducing foam material in hollow sections, which permanently ensures good thermal insulation and at the same time is inexpensive to carry out.
  • the object is achieved by a method for introducing foam material into hollow chamber profiles, in particular window or door hollow chamber profiles, wherein initially the shape of the hollow chamber profile having at least one hollow chamber takes place by way of an extrusion method, foam material then being introduced into at least one hollow chamber, - wherein the foaming process of the foam material takes place at least partially after the introduction of the foam material in the hollow chamber and wherein between the foam material and the wall of the hollow chamber, an intermediate layer is provided which separates the wall in terms of area at least largely from the foam material.
  • the intermediate layer contributes to preventing or at least slowing down the above-described undesired exchange of the cell gas (usually C0 2 ) with air. Accordingly, with the aid of the method according to the invention, the thermal insulation properties present immediately after the production of the hollow-chamber profile can be ensured over a long period of time.
  • the intermediate layer covers at least 70%, preferably at least 80%, eg at least 90%, in particular at least 95%, of the outer surface of the foam material.
  • the total thickness of the intermediate layer conveniently carries less than 500 pm, preferably less than 200 pm, for example less than 100 pm, in particular less than 80 pm. Such thin layers cause only a low material requirement for the intermediate layer, although the desired barrier properties of the intermediate layer for the cell gas are sufficiently present even at these low layer thicknesses.
  • the intermediate layer can consist of a lacquer and / or a plastic and / or a metal.
  • the intermediate layer is sprayed or sputtered onto the wall.
  • Sputtering is a physical process in which atoms are dissolved out of a solid by bombardment with high-energy ions and transferred to the gas phase.
  • the sputtering process usually takes place under a high vacuum and allows a coating of the hollow chamber wall with very low layer thicknesses.
  • the intermediate layer can be produced by means of metal vapor deposition of the hollow chamber wall.
  • Metal vaporization is advantageously additionally ensured that the heat radiation exchange is thereby effectively restricted. It is also within the scope of the invention to apply a liquid coating as an intermediate layer to the surface of the hollow chamber wall, e.g. in the form of a highly pigmented dipping varnish. In the case of a liquid coating, in particular based on water, there is the additional advantage that, at the same time, effective cooling during the production process of the hollow chamber profile is ensured by a part of the liquid evaporating.
  • the intermediate layer is formed as a film, in particular as a film strip formed preferably in accordance with the hollow chamber wall.
  • the foil which is e.g. a carrier layer made of plastic, may have a diffusion-tight layer, for example of metal, which is preferably vapor-deposited on the carrier layer.
  • metal vapor deposition with materials other than metal is not excluded.
  • aluminum may be used as the metal.
  • the foam material is first applied to the film strip, then the film strip provided with the foam material introduced into the hollow chamber and only then completed the foaming process of the foam material.
  • the film strip is expediently initially brought into a groove shape before the foam material reaches the groove-shaped Foil strip is applied.
  • the film strip is expediently further deformed after application of the foam material in such a way that, seen in cross-section, it is transferred as far as possible or, with or without overlap, completely into a closed contour which envelops the foam material.
  • the film strip attaches to the wall of the hollow chamber to be foamed and forms a barrier layer between the foam material and the hollow chamber wall.
  • the amount and nature of the foam material can be such that form during the foaming between the composite of foam material and intermediate layer on the one hand and the wall ofdirectorCumenden hollow chamber on the other hand one or more additional cavities, so that between the intermediate layer and Hohlcrowandung a preferably several mm, for example 2 to 4 mm, strong gap is formed in which there is virtually no convection of the air therein.
  • this gap serves as a further thermal insulation measure.
  • the film strip is dimensioned so that it is in the hollow chamber profile
  • the foil strip when viewed in cross-section, is converted into a closed contour, which envelops the foam material, connected to a tube, e.g. welded, and then introduced into the hollow chamber.
  • the film tube can be advantageously acted upon within the technologicallyumenden hollow chamber with a pressurized gas, eg compressed air, so that it adapts very accurately to the hollow chamber contour. It may be appropriate to carry out the application of the foam material and the tube production in a single operation. This ensures that the foam material remains completely within the film tube as intended.
  • the film strip may be dimensioned or designed such that it does not completely enclose the foam material within the hollow chamber, whereupon during the foaming process an area forms in which the foam material is in direct contact with the hollow chamber wall.
  • This area is now expediently designed so that on the one hand the desired fixation of the foam material in the hollow chamber profile is ensured, but on the other hand the forces for removing the foam material from the hollow chamber remain relatively small during recycle.
  • the barrier function of the intermediate layer is only slightly influenced by the comparatively small direct contact area of foam material and hollow chamber wall.
  • the film has openings, in particular in the form of a perforation. Through these openings, the foam material can pass during the foaming process and locally form a contact to the hollow chamber wall.
  • the foam material is expediently made of an organic material with low thermal conductivity, in particular a polyurethane.
  • a polyurethane for example, the two components polyisocyanate and polyol are introduced with the addition of water in the hollow chamber and take there first a relatively small volume. After mixing of the components, it comes with a time delay to the chemical reaction between the components to form the polyurethane.
