Definitions

  • the invention relates to an incombustible thermal insulation layer of mineral fibers 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 of organic foam such as styrene foam, polyurethane foam and others
  • thermal insulation layers made from such foams are very stiff and hard and can easily transfer the tensile stress of the top layer to the building structure.
  • high strength of the thermal insulation layers made of organic foam also brought considerable disadvantages. Temperature differences of 70 ° C and more can occur on the surface of a building due to solar radiation on the one hand and frost on the other. Normally, this temperature is absorbed and compensated by the building structure, so that there are no significant temperature differences between the building structure and the top layers, so that considerable mechanical stresses occur, which can lead to detachment of the plaster or board material.
  • 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 coating with glass fiber fabric is already mentioned in German patent application No. 2 307 577 and in German utility model 7 319 376, although full-surface bonding 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 fiberglass mesh that is only glued along the threads allows the binder and the plaster layers to access the actual load-bearing lamella core.
  • 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 a fire and allows the use of normal cleaning methods and the application of plate material with binders or adhesives without fear of any damage .
  • the thermal barrier coating consists of mineral fiber slats.
  • Mineral fiber slats are strips of uniform width cut from mineral wool panels, which are rotated by 90 ° and then joined together to form a closed panel. 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 binder and plaster unhindered access to the surface of the fiber slats.
  • the arrangement of this fiber direction has the following effects:
  • the thermal insulation layer 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 is very flexible under stresses parallel to the surface.
  • the fibers act as small pendulum supports. Changes in the length of the top layer can therefore be absorbed without creating any tension against the subsurface or masonry.
  • any stiff coating whether as plaster or as a glued-on plate, cannot detach from the thermal insulation layer after the effect of temperature changes.
  • 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 into uniformly wide strips (3), the lamellae, by the device (2). They are rotated by 90 ° and strung together to form a lamella web (4).
  • Fig. 4 shows schematically the section of a wall piece provided with the thermal insulation system according to the invention in a layered construction.
  • the thermal insulation layer (4) is fastened to the masonry (10) with the aid of the binder (11).
  • a binder layer (12), which in turn securely holds the cover layer (13), is in turn applied to the thermal insulation layer (4).
  • 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 fabric or grid (5) is provided with adhesive (6) and applied to the lamella web (4) by a suitable device (7), so that the fabric (5) connected rollable lamella web (8), which is then delivered in roll form.
  • the inventive trick of only providing the wide-mesh fabric (5) with adhesive (6) achieves the situation shown enlarged in FIG. 2a.
  • the wide-mesh grid (5) is provided with adhesive (6) only along the threads, so that the fibers of the lamella plate (4) are exposed between the threads for wetting with other binders (11 + 12).
  • Fig. 2b shows again the integration of the thread of the fabric (5) with adhesive (6) on the lamella (4). 4 means for the practical implementation this means that the binder layers (11 + 12) adhere directly to the fiber lamella (4), although the fabric (5) is glued to the lamella web (4).
  • the wide-meshed grid (5) can consist of plastic fibers, glass fibers or mineral fibers, but not of fibers that can rot, such as hemp, cotton or similar substances.
  • this wide-mesh grid (5) can not only hold the fiber slats (4) together to form units suitable for processing, but can 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 surrounds it, so that tensions within the binder layer (12) can be taken over by the fabric (5) and thus the formation of cracks in the cover layer (12 + 13) is counteracted.
  • the fabric (5) is cut slightly wider than the lamella web (8) so that a one-sided protrusion (9) is formed, 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 lamella web is connected on one side to a wide-mesh grid (5) provided with adhesive (6), as in FIGS. 1 and 3c, a rollable lamella 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 have been used up to now.
  • 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 therefore 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 on, 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 in a 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, especially glass fibers. This happens in the presence of moisture and can take until the lime is completely carbonized in the cement or lime mortar. This attack can lead to the complete dissolution of the fibers, so that, according to FIG. 4, at the point of contact between the fiber (4) and the binder (11) or plaster (13), the connection can be broken, so that the plaster (13) or the fiber - Slat track (4) drops.
  • mineral fiber lamellae made of basalt 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 on the Basis of 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 boards, the width (for example 200 mm) then gives the thickness of the insulation layer made of fiber slats through the turning process.
