Definitions

  • Vacuum insulation panel encased on both sides with metal-containing composite film or metal cover layer
  • Vacuum isothermal panels are usually used for thermal insulation
  • Vakuumisolie ⁇ aneel e consist of a pre-compressed porous fill, a porous press plate or an open-cell hard foam as a substrate, which is enveloped by a gas-tight film, the film being welded or glued after evacuation
  • Vacuum insulation panels of this type are also already used in the manufacture of cold rooms, for example cooling barriers, by inserting them between the outer and inner housings and foaming the remaining space between the outer and inner housings
  • precipitated and dried silicas Sihcagele, fly ash, open-celled organic foams such as open-celled serve as full materials
  • an asymmetrical structure is selected for the enveloping foils, one side consisting of diffusion-proof aluminum composite foil, the other side being a multi-layer composite made of plastic foil
  • the present invention therefore relates to vacuum isothermal panels which consist of an open-cell substrate coated on all sides with metal-containing composite film or metallic cover layer and have an edge length of at least 40 cm edge length in each case
  • An optionally pre-compressed bed of precipitated silica, silica gel and / or rigid polyurethane foam powder is suitable as the substrate, it being possible for the compression to take place in the presence of suitable adhesives to ensure inherent stability.
  • Open-pore rigid polyurethane foam sheets are also suitable as substrates.
  • plates made of open-pore rigid polyurethane foam or plates made of pre-compressed and optionally bonded rigid polyurethane foam are used as the substrate.
  • the vacuum insulation panels according to the invention have an edge length of at least 40 cm, preferably an edge length 45 cm x 65 cm.
  • the thickness of the panels according to the invention is usually in the range from 0.5 to 5 cm
  • Flexible composite films consisting of at least two layers are preferably used
  • the covering in such a way that differently constructed composite films are used on the front and back of the panels.
  • the composite film on one side can contain a 9 ⁇ m thick aluminum layer, the other a 20 ⁇ m thick aluminum layer
  • Sheet steel plates are preferred as metal-safe cover layers, particularly preferably stainless steel sheet plates.
  • metal-containing composite films or metallic cover layers are already known and commercially available
  • the vacuum insulation panels according to the invention are produced by enveloping the substrate with the gas-tight metal-containing composite film on both sides and then welding or gluing the film in a manner known per se after evacuation, or by enveloping the substrate with the metallic cover layer on both sides, evacuating and hermetically sealing it
  • the Vakuumisoherpaneele invention are used for insulation of Wandun ⁇ gen of Kuhlraumen or refrigeration units such as eg fridges and freezers used
  • the figure shows the cross-section through an inventive Vakuum ⁇ insulating panel consisting of offenpo ⁇ gem Full material 1 (for example with Polyisocyana t verpreßtes polyurethane rigid foam meal as a substrate) and a metal-containing laminated film or metallic covering layer 2
  • offenpo ⁇ gem Full material 1 for example with Polyisocyana t verpreßtes polyurethane rigid foam meal as a substrate
  • a porous 20 mm plate with a bulk density of 200 kg / m 1 is obtained from this.
  • the plate is heated to 120 ° C. for about 2 hours in order to remove all volatile constituents
  • the plate is wrapped with a sheet steel plate on both sides, evacuated and hermetically sealed
  • Rectangular shaped body made of polyurethane foam foam pressed with polyisocyanate (for production, see Example 1). Large 40 * 40 * 2 cm 1 coefficient of thermal conductivity at 0.6 mbar 8.3 mW / mK
  • Vacuum isothermal panel consisting of a rectangular molded body made of rigid polyurethane foam powder pressed with Polvisocyanate (production see example 1) and all-round coating with aluminum composite film containing a 12 ⁇ m thick aluminum layer, internal pressure approx. 0.6 mbar
  • Vacuum isophane consisting of a rectangular molded body made of rigid polyurethane foam powder pressed with polyisocyanate (for production, see Example 1) and all-round wrapping with aluminum composite film, which contains a 12 ⁇ m thick aluminum layer; Internal pressure, about 0.6 mbar
  • Examples 2 to 4 show that from the size of the vacuum panel according to the invention, the aluminum-containing composite film which is used for the encapsulation does not influence the thermal conductivity of the vacuum isothermal panel obtained
