Definitions

  • the invention relates to a non-combustible mineral fiber thermal insulation layer to be applied externally to buildings and industrial facilities, such as, for example, oil tanks, which is simultaneously effective as a carrier of a plaster layer or another surface coating.
  • thermal insulation boards made from organic foam, such as styrene foam, polyurethane foam and others to stick to the object to be insulated or mechanically fixed and then provided with suitable cover layers.
  • Thermal insulation layers made of such foams are very rigid and hard and can easily transfer the tensile stress of the cover layer to the building structure.
  • insulation panels made of organic foam fail when exposed to heat in the event of a fire. Even if such foam panels are flame-retardant, a temperature of only 200 ° C already leads to softening, melting or charring of the material: the applied top layer comes off and endangers the fire-fighting team and other people.
  • the invention has now set itself the task of developing a thermal barrier coating that meets the stresses described, which does not fail in the event of fire and allows the use of normal cleaning methods and the attachment of plate material with binders or adhesives without fear of any damage .
  • the thermal barrier coating consists of mineral fiber slats.
  • Mineral fiber lamellae are strips of mineral wool that are cut uniformly and wide, which are rotated by 90 and put together again to form a closed plate. Such plates have a fiber direction perpendicular to the surface, they have a brush-like structure.
  • this is achieved in that a wide-meshed glass fiber grid is used as a one-sided or two-sided coating of the fiber-lamella plate, which is connected to the lamella strips only along the threads if possible. This leaves the space between the threads of the glass fiber fabric free and allows binders and plaster unhindered access to the surface of the fiber lamella.
  • FIGS. 1-4 are attached to explain the subject matter according to the invention.
  • Fig. 1 shows schematically the manufacturing process of lamellae and their connection with a glass fiber grid. The grain direction can be seen from the hatching.
  • the commercially available mineral fiber plate (1) is cut by the device (2) into strips of equal width (3), the lamellae. They are rotated 90 and lined up to form a lamella web (4).
  • the arrangement of this fiber direction has the following effects:
  • the thermal insulation layer (4) can absorb considerable tensile forces perpendicular to the surface. Values up to 40 N / cm 2 were measured. With such strengths, the anchoring of a top layer on the masonry with the help of a flat connection is more than guaranteed.
  • such a lamella layer (4) is very flexible under stress parallel to the surface.
  • the fibers act as small pendulum supports. Therefore, changes in length of the cover layer can be absorbed without any tension against the substrate or masonry.
  • any rigid coating whether as a plaster or as a glued plate, cannot detach from the thermal insulation layer after the action of temperature changes.
  • Fig. 4 shows schematically the detail of a wall piece provided with the thermal insulation system according to the invention in layered construction.
  • the thermal insulation layer (4) is attached to the masonry (10) with the aid of the Sindem means (11).
  • a binder layer (12) is placed on the heat insulation layer (4), which in turn securely holds the cover layer (13).
  • the layers (12 + 13) can also consist of a two-layer exterior plaster.
  • the thermal barrier coating (4) is shown here, for example, as a rollable slat mat.
  • a wide-mesh grid (5) is provided with adhesive (6) and applied to the lamellar web (4) by suitable devices (7), so that the web (5) is connected Rollable slat track (8) is created, which is then delivered in roll form.
  • the wide-mesh grid (5) is provided with adhesive (6) only along the threads (5), so that the fibers of the lamella plate (4) between the threads (5) are open for wetting with other binders.
  • Fig. 2b shows again the integration of the fiber (5) with adhesive (6) on the lamella (4).
  • the binder layers (11 + 12) adhere directly to the fiber lamellae, although the fabric (5) is glued onto the lamellae web (4).
  • the wide-mesh grid (5) can consist of plastic fibers, glass fibers or mineral fibers, but not of fibers that Can rot, such as hemp, cotton or the like.
  • this wide-mesh grid (5) can not only hold the fiber lamellae (4) together to form units suitable for processing, but also act as reinforcement for an applied binder or plaster layer (12). This is possible because the binder layer (12) penetrates the wide-mesh fabric (5) and in some cases even completely encloses it, so that tensions within the binder layer (12) can be taken over by the fabric (5) and thus crack formation in the cover layer (12 + 13) is counteracted.
  • the fabric (5) is advantageously cut slightly wider than the lamella web (8), so that a one-sided projection (9) is produced which covers the abutting edges of the lamella webs (8), as in FIG 4 shown so that a complete plaster reinforcement is ensured.
  • 3a shows the top view of such a lamella web (8).
  • a fiber lamellar web (4) is connected on one side according to the invention to a wide-mesh grid (5) provided with adhesive (6), as in FIGS. 1 and 3c, a rollable lamellar web (8) is produced.
  • Such a panel can be laid and fastened in the same way as the insulation panels made of flammable rigid foam that were previously used.
  • the coating with glass fiber fabric is already mentioned in German patent application No. 2 307 577 and in German utility model No. 73 19 376, but a full-surface sealing of the coating with the fiber lamella layer is provided.
  • the adhesive acts as a separating layer. There is no essential knowledge that only a wide-meshed glass fiber grid that is only glued along the threads allows the binder and the plaster layers to access the actual load-bearing lamella core.
  • Both organic and inorganic substances can therefore be used as the adhesive (6) for connecting the wide-mesh grid (5) to the fiber lamellae (4). It is also possible to use hot melt adhesives, hot melt adhesives, solvent-based adhesives, welding tracks, furthermore dispersion adhesives, as well as inorganic hydraulically setting adhesives.
  • the adhesive application (6) shown in FIG. 1 by immersion is only an example.
  • the adhesive can also be applied to the fabric by spraying, rolling, inserting a welding foil or other devices belonging to the prior art.
  • the setting or hardening process of the adhesive (6) can be accelerated by the action of heat or the application can be carried out using the hot process, the hardening taking place by cooling.
  • Inorganic binders such as phosphate binders can also be reacted by higher temperatures.
  • the pressing process (7) shown in FIG. 1 can be combined with such a heat treatment with the aid of devices belonging to the prior art.
  • alkaline substances such as Portland cement and white lime hydrate can significantly attack mineral fibers, in particular glass fibers. This happens in the presence of moisture and can continue until the lime in the cement or plastering mortar is completely carbonized. This attack can lead to the complete dissolution of the fibers, so that it is shown in FIG. 4 at the point of contact between fiber (4) and binder (11) or Plaster (12) can come to break the connection, so that the plaster (12 + 13) or the fiber-lamella web (4) falls off.
  • mineral fiber lamellae made of 8 asalt fibers, pozzolana fibers or alumina fibers are preferably used for such a thermal insulation system.
  • a zircon glass specially developed as alkali-resistant can also be used as a fiber raw material. Fibers made from these raw materials can be processed in accordance with the invention in connection with alkali-containing binders such as Portland cement or white lime hydrate if so much lime-binding substances are added to these binders that emerging free lime is reliably bound.
  • alkali-containing binders such as Portland cement or white lime hydrate if so much lime-binding substances are added to these binders that emerging free lime is reliably bound.
  • Such lime-binding substances are pozzolans or active silica. Trass, fly ash and others are known as pozzolans, quartz powder or SiO 2 dusts and other SiO 2 compounds can be used as silica.
  • binder (11 + 12) and Plaster layer (13) uses a dispersion binder based on various known suitable synthetic resins. Such binders and plasters do not attack glass fibers and are weather-resistant. On the other hand, however, these binders and plasters consist of organic substances and disintegrate relatively quickly when exposed to fire.
  • alumina cement can be used as a binder in order to produce suitable connecting layers (11 + 12) and surface coatings (13).
  • Alumina cement does not contain free lime and therefore does not attack glass fibers.
  • any desired insulation layer thickness can be set with a fiber lamella board.
  • Normal mineral wool insulation boards can only be made up to 100 mm thick.
  • the slat strips can be cut to the desired width from any thin raw panels, the width (for example 200 mm) then gives the thickness of the insulation layer made of fiber slats.
