Definitions

  • the invention relates to a thermal insulation board with a covering and core made of solidified thermal insulation material of the following composition:
  • particulate thermal insulation material is usually solidified, for example by pressing.
  • binder which would enable the production of self-supporting panels, is undesirable because the thermal insulation properties suffer as a result.
  • thermal insulation material into sack-like coverings made of, for example, glass fiber and the like, and to produce a plate by sewing or welding and subsequent pressing, in which it is possible to dispense with binders.
  • thermal insulation boards often have seams or burrs on the edges, which affects the dimensional accuracy, so that often difficulties in assembly. especially when joining several panels.
  • Thermal insulation boards that are completely coated with metal sheets or metal foils have also become known. Such panels are mostly tailored to very specific applications within the wide range of thermal insulation measures.
  • Metals reflect heat radiation and, in this respect, have insulating properties. However, on the other hand, they disadvantageously contribute to the heat flow due to their good thermal conductivity.
  • the object of the invention was to develop a thermal insulation board with a metal sheath which does not have the disadvantages described above.
  • Figures A and B show cross sections of thermal insulation boards according to the invention.
  • the core of the plate is covered with metal foil on the opposite sides of the heat flow.
  • the metal foil is preferably folded over the edge and may extend in different lengths beyond the edge. However, it is imperative that the two metal foils do not touch.
  • the metal foils are connected to the heat flow inhibiting material to complete the plate shell.
  • Figure A shows an example of a plate according to the invention, wherein the heat flow-inhibiting part of the plate covering according to c) of the claim comes to lie over the metal foil ends, while according to Figure B the metal foils grip over the larger part of the face of the plate, so that a layer sequence of Metal foil, heat flux-inhibiting material / metal foil comes about.
  • connection between the metal foil and the core consisting of compressed thermal insulation material is preferably adhesive-free, at least on the surfaces of the plate that face the heat flow. If desired, a mechanical connection of the Metal foil with the core can be produced, for example, by appropriate embossing.
  • water glass comes into consideration, which, in order to adjust the viscosity, contains pyrogenic silica and, if appropriate, fibrous reinforcing agents.
  • Maleinate-vinyl acetate copolymers have proven themselves as organic adhesives.
  • the above-mentioned fixed connection is achieved by tensioning, that is to say mechanically.
  • tensioning that is to say mechanically.
  • This can be achieved, for example, by covering the plate with a band of polymer material from the group of fluorocarbons.
  • a mechanical connection can also be made by clipping.
  • the finely divided metal oxide used is preferably low-alkali precipitated silicas or pyrogenically produced silicas, including arc silicas. Further examples are finely divided or microporous species of aluminum oxides and titanium dioxide.
  • the metal oxides can be used individually or in a mixture.
  • the metal oxides have BET surface areas from 50 to 700, preferably 7 0 to 40 0 m 2 / g.
  • opacifiers are ilmenite, titanium dioxide, silicon carbide, iron (II) iron (III) mixed oxide, chromium dioxide, zirconium oxide, manganese dioxide and iron oxide.
  • the opacifiers advantageously have an absorption maximum in the infrared range between 1.5 and 10 ⁇ m.
  • the fiber material used is glass wool, rock wool, slag wool, ceramic fibers such as those obtained from melts of aluminum oxide and / or silicon oxide, asbestos fibers and others.
  • the thermal insulation material is obtained by simply mixing the components in the desired composition.
  • so-called agglomerated mixtures in particular based on pyrogenic silica, can also be used.
  • the procedure here is such that the opacifier is added continuously in the desired mixing ratio already during the production process of the silica, in which the silica is still in the form of the primary particles.
  • Aluminum foil is preferred as the metal foil. However, all other metallic foils can also be processed, in particular for more special applications, which have also previously been used for cladding thermal insulation materials.
  • the films usually have a thickness of 10 to 80 ⁇ m, preferably about 40 ⁇ m.
  • fabric made of, for example, glass fiber or asbestos can be considered.
  • polymer material based on fluorocarbon or a film-forming paint e.g. Water glass can be used. However, it is always a non-metallic material.
  • the thermal insulation material is filled into a mold and preferably pressed at a pressure of about 10 kp / cm 2 .
  • the gases enclosed in the mixture should be able to escape during compression. Therefore, the pressing is preferably carried out with the application of negative pressure. Degassing can also take place or begin before the pressing.
  • the compacted core is then provided with metal foil, folded at the edges and the covering is completed by attaching a preferably band-shaped material which inhibits the heat flow. Depending on the material, this can be done by gluing, bracing or by attaching clips, preferably by gluing.
  • the method can also be modified to the extent that the metal foils are already installed when the thermal insulation material is pressed.
  • the procedure is preferably such that one of the two metal foils is placed in the mold, the thermal insulation material is pre-compressed, the second metal foil is applied to the pre-compressed heat material, and the workpiece is finally pressed into its final shape.
  • the non-metallic part of the plate covering can be applied to the core or between the metal foils.
  • the good dimensional stability of the plates is also advantageous. Since the plates according to the invention can be formed with sharp edges without difficulty, assembly that is true to the joint is ensured.
  • thermal insulation boards not only a flat but also a curved shape.
