Description

Die Erfindung bezieht sich auf eine unbrennoare, außen auf Gebäude und industrielle Einrichtungen, wie zum Beispiel Öltanks, aufzubringende Wärmedämmschicht aus Mineralfasern, die gleichzeitig als Träger einer Putzschicht oder einer anderen Oberflächen-Beschichtung wirksam ist.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.

Es ist bekannt, Gebäude und andere Objekte von außen mit Mineral- Faser-Platten oder -Matten gegen Wärmeverluste zu schützen. Dies wird meist in der Weise durchgeführt, daß Platten oder rollbare Matten aus Glas- oder Mineralwolle durch Ankleben, Annageln oder Anschrauben an dem zu isolierenden Objekt befestigt werden, während zusätzlich eine Verkleidung auf einem dafür geeigneten Unterbau (zum Beispiel Zementasbest-Platten auf Lattenrost) zum Schutz von Wärmedämmung und Baukörper gegen Witterungseinflüsse angebracht wird. Fachlich wird ein solches System als vorgehängte Fassade bezeichnet. Eine solche Konstruktion ist jedoch sehr aufwendig. Es lag daher nahe, die Mineralfaser-Platten ohne die aufwendige Konstruktion einer vorgehängten Fassade unmittelbar mit einer schützenden Deckschicht zu versehen, die aus Putz oder aufgeklebten Platten bestehen kann. Solche Deckschichten haben jedoch nicht gehalten, weil sich die Mineralfaser-Platten infolge ihrer losen Bindung und der parallel zur Oberfläche verlaufenden Faserrichtung sehr leicht spalten lassen. Die Verankerung der Deckschichten am Baukörper ist daher völlig unzureichend.It is known to protect buildings and other objects from the outside with heat, using mineral fiber boards or mats. This is usually done in such a way that panels or rollable mats made of glass or mineral wool are attached to the object to be insulated by gluing, nailing or screwing on, while additionally cladding on a suitable substructure (e.g. cement asbestos panels on slatted base) to protect thermal insulation and structures against weather influences. Such a system is technically known as a curtain wall. However, such a construction is very complex. It therefore made sense to provide the mineral fiber panels with a protective cover layer, which can consist of plaster or glued panels, without the complex construction of a curtain wall. However, such cover layers have not held because the mineral fiber boards are very easy to split due to their loose binding and the direction of the fibers running parallel to the surface. The anchoring of the cover layers on the structure is therefore completely inadequate.

Man hat daher versucht, anstelle der Mineralfaser-Platten Wärmedämmplatten aus organischem Schaum, wie Styrolschaum, Polyurethanschaum und anderen an das zu isolierende Objekt anzukleben oder auch mechanisch zu oefestigen und dann mit geeigneten Deckschichten zu versehen. Wärmedämmschichteh aus solchen Schäumen sind sehr steif und hart und können die Zugbeanspruchung der Deckschicht leicht auf den Baukörper übertragen.Attempts have therefore been made to replace the mineral fiber boards with 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.

Es hat sich jedoch bald gezeigt, daß die hohe Festigkeit der Wärmedämmschichten aus organischem Schaum gleichzeitig erhebliche Nachteile brachte. Auf der Oberfläche eines Baukörpers können durch Sonneneinstrahlung einerseits und durch Frost andererseits Temperatur-Differenzen von 70°C und mehr auftreten. Normaler Weise wird diese Temperatur vom Baukörper aufgenommen und ausgeglichen, sodaß zwischen Baukörper und Deckschichten keine so wesentlichen Temperaturdifferenzen entstehen, daß dadurch erhebliche mechanische Spannungen auftreten, die zur Ablösung des Putzes oder Platten-Materials führen können.However, it soon became apparent that the 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 for by the structure, so that there are no significant temperature differences between the structure and cover layers, so that considerable mechanical stresses occur which can lead to detachment of the plaster or plate material.

Anders ist die Situation jedoch, wenn zwischen Baukörper und Deckschicht eine Wärmedämmschicht vorhanden ist. In diesem Fall bleibt die Baukörpertemperatur konstant, während die Temperatur der Deckschicht erheblich schwankt, weil der Wärmeübergang und damit der Temperaturausgleich durch die Wärmedämmschicht verhindert wird. Das hat zur Folge, daß die Deckschicht aus Putz oder Plattenmaterial je nach Temperatureinwirkung erheblichen Längenänderungen unterworfen ist, sodaß Spannungen entstehen können, die bei unnachgiebigem Untergrund zur Ablösung der Deckschicht führen.The situation is different, however, if a thermal insulation layer is present between the structure and the top layer. In this case, the building body temperature remains constant, while the temperature of the cover layer fluctuates considerably, because the heat transfer and thus the temperature compensation by the thermal insulation layer is prevented. The consequence of this is that the top layer of plaster or board material is subjected to considerable changes in length depending on the temperature effect, so that tensions can arise which lead to detachment of the top layer when the surface is unyielding.

Auch das Armieren der Deckschicht aus Putzmörtel mit Glasfasergewebe und das Überdecken der Fugen der Wärmedämmplatten mit Gewebestreifen oder Faservlies konnte diesem Übelstand nicht abhelfen.Reinforcing the top layer of plastering mortar with glass fiber fabric and covering the joints of the thermal insulation boards with fabric strips or non-woven fabric could not remedy this problem.

Aus dem gleichen Grunde kam es auch zu Schäden bei der Verwendung der an sich weichen Mineralfaser-Platten oder -matten, weil hier zwar nicht die Deckschicht von den Platten abriß, jedoch die Platten selber aufspalteten und damit die Haftung der Deckschicht am Gebäude unterbrochen wurde.For the same reason, there was also damage when using the mineral fiber panels or mats, which were soft per se, because although the top layer did not tear off from the panels here, the panels themselves split and thus the adhesion of the top layer to the building was interrupted.

Weiterhin versagen Dämmplatten aus organischem Schaum bei Hitzeeinwirkung im Brandfall. Selbst wenn solche Schaumstoff-Platten schwerentflammbar eingestellt sind, so führt eine Temperatur von nur 200°C bereits zur Erweichung, zum Abschmelzen oder Verkohlung des Materials: die aufgebrachte Deckschicht löst sich ab und gefährdet die Löschmannschaft und andere Personen.Furthermore, 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.

Die Erfindung hat sich nun die Aufgabe gestellt, eine Wärmedämmschicht zu entwickeln, die den geschilderten Beanspruchungen gerecht wird, die im Brandfall nicht versagt und die Anwendung normaler Putzmethoden sowie die Anbringung von Plattenmaterial mit Bindemitteln beziehungsweise mit Klebstoffen gestattet, ohne daß irgendwelche Schäden zu befürchten sind.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 .

Erfindungsgemäß besteht die Wärmedämmschicht aus Mineralfaser-Lamellen. Als Mineralfaser-Lamellen werden aus Mineralwolle-Platten geschnittene gleichmäßig breite Streifen bezeichnet, die um 90 gedreht und wieder zu einer gschlossenen Platte zusammengefügt werden. Solche Platten weisen eine Faserrichtung senkrecht zur Oberfläche auf, sie haben eine bürstenartige Struktur.According to the invention, 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.

Nun ist bekannt, daß Dämmschichten aus Mineralfasern, bei denen die Faserrichtung senkrecht zur Oberfläche wie bei einer Bürste eingestellt ist, eine sehr hohe Eigenfestigkeit aufweisen. Bereits 1937 wurde in den USA das Patent Nr. 2 160 001 angemeldet, das eine belastbare Dämmschicht aus quer zur Plattenebene eingestellten Fasern beschreibt. Da man jedoch solche Faserstreifen nicht einzeln am Bau ankleben kann, sondern bei fast allen Anwendungsformen, wie zum Beispiel auch bei der Herstellung von Sandwich-Elementen mit einem Faserkern, Feuerschutztüren usw. eine leicht hantierbare Platte braucht, sind eine Reihe von Vorschlägen gemacht worden, solche Bahnen oder Platten mit einseitiger oder zweiseitiger Kaschierung oder Beschichtung herzustellen. Solche Faserlamellen-Platten oder -Bahnen sind in den folgenden Patentschriften oder -Anmeldungen näher beschrieben:

  • US-Patente Nr. ; 373 500, 2 546 230, 2 949 953, 3 012 923, 3 048 513, 3 230 995, 3 345 341, 3 736 215; deutsche Patente Nr. 1 047 702, 1 459 973, 1955 624, 2 223 101, 2 307 577, 2 307 873, 2 327 428 sowie das deutsche Gebrauchsmuster 73 19 376, sowie weitere Patentschriften mit ähnlichem Inhalt.
It is now known that insulating layers made of mineral fibers, in which the fiber direction is set perpendicular to the surface like a brush, have a very high inherent strength. As early as 1937, patent application no. 2 160 001 was filed in the USA, which describes a resilient insulation layer made of fibers set transversely to the board level. However, since it is not possible to glue such fiber strips individually to the building, but for almost all types of application, such as for example in the production of sandwich elements with a fiber core, fire protection doors, etc., an easily manageable plate is required, a number of proposals have been made, to produce such sheets or plates with one-sided or two-sided lamination or coating. Such fiber lamella sheets or webs are described in more detail in the following patents or applications:
  • U.S. Patents No.; 373 500, 2 546 230, 2 949 953, 3 012 923, 3 048 513, 3 230 995, 3 345 341, 3 736 215; German patents No. 1 047 702, 1 459 973, 1955 624, 2 223 101, 2 307 577, 2 307 873, 2 327 428 and German utility model 73 19 376, as well as other patent specifications with similar content.

Allen diesen Vorschlägen ist eigen, daß die Beschichtung zum Zusammenhalten der Faserlamellen-Streifen vollflächig erfolgt, sodaß sie immer als Trennschicht zwischen der eigentlichen Faser- Lamellen-Platte und dem zu isolierenden Objekt wirkt, auf dem die Lamellen-Platte oder Lamellen-Rollbahn mit Hilfe eines Bindemittels aufgebracht werden soll. In gleicher Weise wirkt eine solche Beschichtung bei dem Auforingen der Putzschichten. Weiterhin wird in einigen der genannten Schriften die Verwendung einer Papierbahn als Beschichtung vorgeschlagen. Damit fällt aber im Brandfall das System auseinander.All of these proposals have the characteristic that the coating for holding the fiber lamella strips together takes place over the entire surface, so that it always acts as a separating layer between the actual fiber-lamella plate and the object to be insulated, on which the lamella plate or lamella roller track is to be applied with the aid of a binder. Such a coating acts in the same way when the plaster layers are opened. Furthermore, the use of a paper web as a coating is proposed in some of the cited documents. In the event of a fire, however, the system falls apart.

Hier setzt nun der erfindungsgemäße Gedanke ein. Um eine dauerhafte, brandsichere Sefestigung von Untergrund + Faser-Lamellen- Platte + Putzschicht zu erreichen, muß das Bindemittel und der. Putz unmittelbar ohne störende Zwischenschicht mit den Faser- Lamellen in Berührung kommen.This is where the idea of the invention begins. In order to achieve a permanent, fire-proof fixing of the substrate + fiber slat plate + plaster layer, the binder and the. Get the plaster in direct contact with the fiber lamellas without a disturbing intermediate layer.

Erfindungsgemäß wird das dadurch erreicht, daß als einseitige oder zweiseitige Beschichtung der Faser-Lamellen-Platte ein weitmaschiges Glasfaser-Gitternetz verwendet wird, das möglichst nur entlang der Fäden mit den Lamellenstreifen verbunden wird. Damit bleibt der Zwischenraum zwischen den Fäden des Glasfasergewebes frei und ermöglicht Bindemittel und Putz ungehinderten Zutritt zu der Oberfläche der Faser-Lamellen.According to the invention 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.

Zur Erläuterung des erfindungsgemäBen Gegenstandes sind die Zeichnungen Fig. 1 - 4 beigefügt. Fig. 1 zeigt schematisch den Herstellungsvorgang von Lamellen und deren Verbindung mit einem Glasfaser- Gitternetz. Aus den Schraffuren ist die Faserrichtung ersichtlich. Die handelsübliche Mineralfaser-Platte (1) wir durch die Vorrichtung (2) in gleichmäßig breite Streifen (3), die Lamellen geschnitten. Sie werden um 90 gedrehtund zu einer Lamellenbahn (4) aneinander gereiht.The drawings 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).

Die Anordnung dieser Faserrichtung hat die folgenden Effekte: Die Wärmedämmschicht (4) kann senkrecht zur Oberfläche erhebliche Zugkräfte aufnehmen. Es wurden Werte bis zu 40 N/cm2 gemessen. Mit solchen Festigkeiten ist die Verankerung einer Deckschicht auf dem Mauerwerk mit Hilfe einer flächigen Verbindung mehr als gewährleistet.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.

Andererseits ist eine solche Lamellenschicht (4) bei Beanspruchuncen parallel zur Oberfläche sehr nachgiebig. Die Fasern wirken gleich kleinen Pendelstützen. Daher können Längenänderungen der Deckschicht aufgenommen werden, ohne daß Spannungen gegenüber dem Untergrund oder Mauerwerk entstehen. Somit ist bei einer solchen erfindungsgemäßen Wärmedämmung gewährleistet, daß eine beliebige steife Beschichtung, sei es als Putz oder als aufgeklebte Platte, nach Einwirkung von Temperaturänderungen sich nicht von der Wärmedämmschicht lösen kann.On the other hand, 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. Thus, with such thermal insulation according to the invention it is ensured that 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 zeigt schematisch den Ausschnitt eines mit dem erfindungsgemäßen Wärmedämmsystem versehenen Wandstücks in schichtweisem Aufoau. Auf dem Mauerwerk (10) ist die Wärmedämmschicht (4) mit Hilfe des Sindemittels (11) befestigt. Auf der Wärmedämmschicht (4) ist wiederum eine Bindemittelschicht (12) aufgeoracht, die wiederum die Deckschicht (13) sicher festhält. Die Schichten (12 + 13) können ebenfalls aus einem zweischichtigen Außenputz bestehen.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). In turn, 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.

Die Wärmedämmschicht (4) ist hier beispielsweise als rollbare Lamellen-Matte gezeigt. Um das zu erreichen, wird erfindungsgemäß, wie in Fig. 1 dargestellt, ein weitmaschiges Gitternetz (5) mit Klebstoff (6) versehen und durch geeignete Vorrichtungen (7) auf die Lamellenbahn (4) aufgebracht, sodaß die mit Gewebe (5) verbundene rollbare Lamellenbahn (8) entsteht, die dann in Rollenform angeliefert wird.The thermal barrier coating (4) is shown here, for example, as a rollable slat mat. In order to achieve this, according to the invention, as shown in FIG. 1, 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.

Durch den erfindungsgemäßen Kunstgriff, nur das weitmaschige Gewebe (5) mit Klebstoff (6) zu versehen, wird die in Fig. 2a vergrößert dargestellte Situation erreicht. Auf der Lamellenbahn (4) ist das weitmaschige Gitternetz (5) nur entlang der Fäden (5) mit Klebstoff (6) versehen, sodaß die Fasern der Lamellenplatte (4) zwischen den Fäden (5) zur Benetzung mit anderen Bindemitteln offen liegen. Fig. 2b zeigt nocheinmal vergrößert die Einbindung der Faser (5) mit Klebstoff (6) auf der Lamelle (4). Für die praktische Ausführung gemäß Fig. 4 bedeutet das, daß die Bindemittelschichten (11 + 12) unmittelbar an den Faserlamellen haften, obgleich das Gewebe (5) auf der Lamellenbahn (4) aufgekleot ist. Das weitmaschige Gitternetz (5) kann aus Kunststoffasern, Glasfasern oder Mineralfasern bestehen, jedoch nicht aus Fasern, die verrotten Können, wie Hanf, Baumwolle oder ähnlichem.By the inventive trick to provide only the wide-mesh fabric (5) with adhesive (6), the situation shown in FIG. 2a is achieved. On the lamella web (4), 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). For the practical embodiment according to FIG. 4 this means that 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.

Erfindungsgemäß kann dieses weitmaschige Gitternetz (5) nicht nur die Faserlamellen (4) zu veraroeitungsgerechten Einheiten zusammenhalten, sondern auch als Armierung für eine aufgebrachte Binder- oder Putzschicht (12) wirken. Das ist dadurch möglich, weil die Binderschicht (12) das weitmaschige Gewebe (5) durchdringt und teilweise sogar völlig umschließt, sodaß Spannungen innerhelb der Binderschicht (12) von dem Gewebe (5) übernommen werden können und somit einer Rißbildung in der Deckschicht (12 + 13) entgegengewirkt wird.According to the invention, 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.

Vorteilhafter Weise wird, wie in Fig. 3a - c dargestellt, das Gewebe (5) etwas breiter als die Lamellenbahn (8) zugeschnitten, damit ein einseitiger Überstand (9) entsteht, der die Stoßkanten der Lamellenbahnen (8) überdeckt, wie in Fig. 4 dargestellt, so daß eine lückenlose Putzarmierung sichergestellt ist. Fig. 3a zeigt die Aufsicht auf eine solche Lamellenbahn (8).As shown in FIGS. 3a-c, 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).

Wird eine Faserlamellenbahn (4) einseitig erfindungsgemäß mit einem mit Klebstoff (6) versehenen weitmaschigen Gitternetz (5) wie in Fig. 1 und Fig. 3c verbunden, entsteht eine rollbare Lamellenbahn (8).If 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.

Wird jedoch die andere Seite der Lamellenbahn (4) ebenfalls auf erfindungsgemäße Weise mit einem weitmaschigen mit Klebstoff (6) versehenen Gitternetz (5) verbunden, so entsteht eine steife Lamellenplatte nach Fig. 3b.However, if the other side of the lamella web (4) is also connected in the manner according to the invention with a wide-meshed grid (5) provided with adhesive (6), a rigid lamella plate according to FIG. 3b is produced.

Eine solche Platte kann in gleicher Weise verlegt und befestigt werden, wie die bisher üblicher Weise verwendeten Dämmplatten aus brennbarem Hartschaum.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.

Die Beschichtung mit Glasfasergewebe ist zwar schon in der deutschen Patentanmeldung Nr. 2 307 577 und in dem deutschen Gebrauchsmuster Nr. 73 19 376 erwähnt, wooei jedoch eine vollfläcnige Versletung der Beschichtung mit der Faserlamellenschicht vorgesehen ist. Der Klebstoff wirkt als Trennschicht. Es fehlt die wesentliche Erkenntnis, daß nur ein weitmaschiges nur entlang der Fäden verklebtes Glasfasergitternetz den Zutritt des Bindemittels und der Putzschichten zum eigentlichen tragenden Lamellenkern ermöglicht.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.

Da nun erfindungsgemäß nach Fig. 4 die Verankerung (11) der Wärmedämmschicht aus Faserlamellen (4) nit dem Untergrund (10) und die der Deckschichten (12 + 13) mit den Faserlamellen (4) unmittelbar mit der Faser (4) erfolgt, können die Klebstoffe (6) zur Verbindung des weitmaschigen Gewebes (5) und der Faserlamellen (4) beliebiger Art sein, da sie auf den Zusammenhalt des gesamten Systems keinen Einfluß haben.4, since the anchoring (11) of the thermal insulation layer made of fiber lamellae (4) with the substrate (10) and that of the cover layers (12 + 13) with the fiber lamellae (4) takes place directly with the fiber (4) be the adhesives (6) for connecting the wide-mesh fabric (5) and the fiber lamellae (4) of any kind, since they have no influence on the cohesion of the entire system.

Es können daher als Kleber (6) zur Verbindung des weitmaschigen Gitternetzes (5) mit den Faserlamellen (4) sowohl organische als auch anorganische Substanzen verwendet werden. Danr ist auch die Anwendung von Schmelzklebern, Heißklebern, lösungsmittelhaltigen Klebern, Schweißbahnen, ferner Dispersionsklebern, sowie anorganischen hydraulisch abbindenden Klebern möglich. Die in Fig. 1 gezeigte Klebstoffapplikation (6) durch Eintauchen ist nur beispielhaft. Ebenso kann der Kleber durch Aufspritzen, Aufwalzen, Einlegen einer Schweißfolie oder andere zum Stand der Technik gehörende Vorrichtungen auf das Gewebe aufgetragen werden. Je nach Temperaturbeständigkeit der verwendeten Gewebefasern (5) kann der Abbinde- oder Erhärtungsprozess des Klebers (6) mit Hitzeeinwirkung beschleunigt werden oder der Auftrag im HeiBverfahren erfolgen, wobei die Erhärtung durch Abkühlung erfolgt. Ebenso können anorganische Binder, wie Phosphatbinder durch höhere Temperaturen zur Reaktion gebracht werden. Der in Fig. 1 gezeigte Andrückvorgang (7) kann mit Hilfe zum Stand der Technik gehörender Einrichtungen mit einer solchen Hitzebehandlung kombiniert werden.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. Depending on the temperature resistance of the fabric fibers (5) used, 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.

Bei der Auswahl des Binders zwischen Untergrund und Faserlamellen sowie des Binders zur Befestigung der Deckschicht beziehungsweise des Putzes auf den Wärmedämmbahnen aus Faserlamellen sind wesentlich Fakten zu berücksichtigen, um die Beständigkeit solche Verbindungen sicherzustellen.When choosing the binder between the substrate and the fiber lamellae, as well as the binder for fastening the top layer or the plaster on the thermal insulation sheets made of fiber lamellae, essential facts must be taken into account to ensure the resistance of such connections.

Die Erfahrung hat gezeigt, daß alkalische Stoffe wie Portlandzement und Weißkalkhydrat Mineralfasern, insbesondere Glasfasern erheblich angreifen können. Das geschieht bei Anwesenheit von Feuchtigkeit und kann solange andauern, bis der Kalk im Zement oder Putzmörtel vollständig karbonisiert ist. Dieser Angriff kann zur vollständigen Auflösung der Fasern führen, sodaß es nach Fig. 4 an der Berührungsstelle zwischen Faser (4) und Bindemittel (11) beziehungsweise Putz (12) zur Auflösung der Verbindung kommen kann, soda3 der Putz (12 + 13) oder die Faser-Lamellenbahn (4) abfällt.Experience has shown that 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.

Erfindungsgemäß wird dieser Gefahr wie folgt begegnet. Umfangreiche Versuchsreihen haben gezeigt, daß die Intensität einer Alkalireaktion mit Mineralfasern aus verschiedenen Rohstoffen sehr verschieden ist. Am wenigsten resistent sind Glasfasern, wesentlich besser ist das Verhalten von Mineralfasern aus kalkarmen Basalt oder aus Rohstoffen, die nach der Schmelze ein Puzzolan bilden.According to the invention, this danger is countered as follows. Extensive series of tests have shown that the intensity of an alkali reaction with mineral fibers from different raw materials is very different. Glass fibers are the least resistant; the behavior of mineral fibers from low-lime basalt or from raw materials that form a puzzolan after melting is much better.

Daher werden erfindungsgemäß für ein solches Wärmedämmsystem vorzugsweise Mineral-Faser-Lamellen aus 8asaltfasern, Puzzolanfasern oder Tonerdefasern eingesetzt. Auch läßt sich ein speziell als alkaliresistent entwickeltes Zirkonglas als Faserrohstoff verwenden. Fasern aus diesen Rohstoffen können in Verbindung mit alkalihaltigen Bindemitteln wie Portlandzement oder Weißkalkhydrat erfindungsgemäß verarbeitet werden, wenn diesen Bindern soviel kalkbindende Stoffe beigegeben werden, daß austretender freier Kalk zuverlässig gebunden wird. Solche kalkbindenden Stoffe sind Puzzolane oder aktive Kieselsäure. Als Puzzolane sind bekannt Trass, Flugasche und andere, als Kieselsäure können Quarzmehl oder Si02-Stäube sowie andere Si02-Verbindungen verwendet werden.Therefore, according to the invention, 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. 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.

Soll eine mögliche Reaktion zwischen Faser-Lamellen-Schichten (4) und Binder (11 + 12) grundsätzlich vermieden werden, insbesondere dann, wenn die Faser-Lamellen-Schicht aus handelsüblicher Glasfaser besteht, so wird als Binder (11 + 12) und als Putzschicht (13) erfindungsgemäß ein Dispersionsbinder verwendet auf der Basis verschiedener bekannter geeigneter Kunstharze. Solche Binder und Putze greifen Glasfasern nicht an und sind witterungsbeständig. Andererseits jedoch bestehen diese Binder und Putze aus organischen Stoffen und zerfallen bei Brandeinwirkung relativ rasch.If a possible reaction between fiber-lamella layers (4) and binder (11 + 12) is to be avoided in principle, especially if the fiber-lamella layer consists of commercially available glass fiber, then as binder (11 + 12) and as Plaster layer (13) according to the invention 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.

Soll nun eine besonders temperaturbeständige Befestigung und Seschichtung der Wärmedämmschicht aus Faser-Lamellen (4) erfolgen, so kann erfindungsgemäß als Bindemittel Tonerdeschmelzzement verwendet werden, um geeignete Verbindungsschichten (11 + 12) und Oberflächen-Beschichtungen (13) herzustellen. Tonerdeschmelzzement enthält keinen freien Kalk und greift daher auch Glasfasern nicht an.If a particularly temperature-resistant fastening and layering of the thermal insulation layer made of fiber lamellae (4) is to be carried out, then, according to the invention, 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.

Ergänzend soll erwähnt werden, daß mit einer Faserlamellen-Platte jede gewünschte Dämmschichtdicke einstellbar ist. Normale Dämmplatten aus Mineralwolle können nur bis 100 mm Dicke gefertigt werden. Aus beliebig dünnen Rohplatten können die Lamellenstreifen in der gewünschten Breite geschnitten werden, die Breite (zum Beispiel 200 mm) ergibt dann die Dicke der Dämmschicht aus Faserlamellen.In addition, it should be mentioned that 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.

Das erfindungsgmäße Wärmedämmsystem stellt einen erheblichen technischen Fortschritt dar, weil es folgende Eigenschaften in sich vereint:

  • - Beliebig einstellbare Schichtdicke
  • - Zugfeste Verbindung zwischen Untergrund und Oberfläche
  • - Spannungsfreie Kompensation temperaturbedingter Längenänderungen der Oberfläche
  • - Armierung der Oberflächenschicht ohne zusätzlichen Aufwand
  • - hohe Wärmedämmung

  • - unverrrottbare Bestandteile
  • - offene Porosität = keine Feuchtigkeitsspeicherung
  • - einfache Befestigung mit bekannten Bindemitteln und handelsüblichem Gerät
  • - Reaktionssichere Verbindung von Fasern und Bindemittel
The thermal insulation system according to the invention represents a significant technical advance because it combines the following properties:
  • - Layer thickness can be set as required
  • - Tension-resistant connection between the surface and the surface
  • - Stress-free compensation of temperature-related changes in length of the surface
  • - Reinforcement of the surface layer without additional effort
  • - high thermal insulation
  • - non-flammable
  • - non-rotting components
  • - open porosity = no moisture retention
  • - Easy attachment with known binders and standard equipment
  • - Reaction-proof connection of fibers and binders
