Abstract
Description
Die Erfindung betrifft ein Brandschutzlaminat, welches bei höheren Temperaturen aufschäumt und somit einen Schutz gegen die Einwirkung von Feuer bewirkt. Flammschutzschichten unter Verwendung von mit Alkalisilikat getränkten Fasern sind bekannt. So wird in der DE-AS 11 69 832 ein Verfahren zur Herstellung von thermisch isolierenden Flammschutzschichten beschrieben, bei dem anorganische und/oder synthetische organische Fasern oder daraus hergestellte Gewebe mit einer Schicht einer Alkalisilikatlösung versehen werden. Durch Trocknen werden diese Schichten verfestigt. Gegen den schädlichen Einfluß von Wasser erhalten solche Schichten einen Überzug aus wasserunlöslichem Material.The invention relates to a fire protection laminate, which at higher temperatures foams and thus provides protection against the effects of fire. Flame protection layers using fibers impregnated with alkali silicate are known. DE-AS 11 69 832 describes a process for the production of Thermally insulating flame retardant layers described in the inorganic and / or synthetic organic fibers or fabrics made therefrom with a Layer of an alkali silicate solution. By drying these Layers solidified. Against the harmful influence of water, those get Lay a coating of water-insoluble material.
Brandschutzlaminate dieser Art genügen heute nicht mehr den an sie gestellten Anforderungen. Sie verlieren z. B. unter dem Einfluß von Kohlendioxid die Eigenschaft, bei Feuer aufzuschäumen. Es bestand daher die Aufgabe, Brandschutzlaminate der beschriebenen Art so zu verbessern, daß sie über längere Zeiträume gegenüber dem Einfluß von Wasser und Kohlendioxid stabil bleiben und somit ihre Schutzfunktion beibehalten. Dies gilt insbesondere in den Fällen, wo nach dem Einbau der Brandschutzlaminate ein späterer Zugriff zu ihnen nicht mehr möglich ist.Fire protection laminates of this type are no longer sufficient for them Conditions. You lose e.g. B. under the influence of carbon dioxide Ability to foam up on fire. It was therefore the task Improve fire protection laminates of the type described so that they last longer Periods of time remain stable against the influence of water and carbon dioxide and thus maintain their protective function. This is especially true in cases where after installing the fire protection laminates, access to them is no longer possible is possible.
Außerdem sollten die Brandschutzlaminate nur ökologisch unbedenkliche Materialien enthalten und bei Feuer keine giftigen Stoffe entwickeln. Bedenkliche Materialien, wie chlorhaltige Kunststoffolien, sollten bei ihrer Herstellung ausgeschlossen werden. In addition, the fire protection laminates should only use ecologically harmless materials contain and develop no toxic substances in fire. Questionable materials, such as chlorine-containing plastic films, should be excluded in their manufacture become.
Schließlich sollte die Herstellung der neuen Brandschutzlaminate auf möglichst einfachem Wege erfolgen, wobei Änderungen der verwendeten Materialien, insbesondere der Verbundfolien, den Herstellungsablauf möglichst gering beeinträchtigen sollten.Finally, the production of the new fire protection laminates should be possible easy way, changing the materials used, especially the composite films, the manufacturing process as low as possible should affect.
Zur Lösung dieser Aufgabe werden Brandschutzlaminate entsprechend Anspruch 1 vorgeschlagen. Bevorzugte Laminate sind in den Unteransprüchen beschrieben.To solve this problem, fire protection laminates are used according to claim 1 suggested. Preferred laminates are described in the subclaims.
Die zentrale Schicht des erfindungsgemäßen Brandschutzlaminats stellt eine mit einer Natriumsilikatlösung behandelte Brandschutzschicht dar. Ihre Herstellung erfolgt auf allgemein bekannte Weise, z. B. nach dem Verfahren der DE-AS 11 69 832. Man behandelt eine Matte aus Glasfaser, Steinwolle u. dergl. mit einer Natriumsilikatlösung und entfernt den größten Teil des Wassers bei erhöhter Temperatur, ohne daß die zu trocknende Matte sich aufbläht. Das Wasser darf nicht vollständig entfernt werden, weil es als Treibmittel wirkt.The central layer of the fire protection laminate according to the invention provides one a fire protection layer treated with a sodium silicate solution. Their production takes place in a generally known manner, e.g. B. according to the method of DE-AS 11 69 832. A mat made of glass fiber, rock wool and the like is treated. the like with a Sodium silicate solution and removes most of the water at elevated Temperature without the mat to be dried puffing up. The water is allowed cannot be removed completely because it acts as a blowing agent.
Als Natriumsilikatlösung kann im einfachsten Fall übliches Wasserglas verwendet werden. Zusätze, wie Siliziumdioxid, Talkum, Titandioxid u. dergl. oder Netzmittel, wie sie auch in der DE-AS 11 69 832 beschrieben werden, ergeben verbesserte Produkte. Die fertige Brandschutzschicht besitzt eine Dicke zwischen 1,6 und 4,0 mm, vorzugsweise zwischen 1,6 und 2,4 mm.In the simplest case, conventional water glass can be used as the sodium silicate solution become. Additives such as silicon dioxide, talc, titanium dioxide and the like. the like. or wetting agents, as they are also described in DE-AS 11 69 832 result in improved Products. The finished fire protection layer has a thickness between 1.6 and 4.0 mm, preferably between 1.6 and 2.4 mm.
Die verwendeten Folien können aus beliebigem polymeren Material bestehen. Bevorzugt sind Polyethylen, Polypropylen, Polyamid, Polyester oder ein Ionomer. Bei den Aluminiumfolien verwendet man solche mit einer Dicke von 9 bis 20 µm, insbesondere von 12 µm. The films used can consist of any polymeric material. Polyethylene, polypropylene, polyamide, polyester or an ionomer are preferred. Aluminum foils are used with a thickness of 9 to 20 µm, especially 12 µm.
Als Papierschichten können beliebige Papiere eingesetzt werden. Als besonders vorteilhaft erwiesen sich Natronkraftpapiere mit einem Mindestgewicht von 20 g/qm. Anstelle von Papier kann auch ein Glasfasergewebe eingesetzt werden welches im Laminat im Gegensatz zu der bereits beschriebenen Fasermatte nicht mit Silikat getränkt ist. Es kann unterschiedlich strukturiert sein und weist ein Flächengewicht von 30 bis 50 g/qm auf.Any paper can be used as paper layers. As special Sodium kraft papers with a minimum weight of 20 g / sqm proved to be advantageous. Instead of paper, a glass fiber fabric can also be used In contrast to the fiber mat already described, laminate does not contain silicate is soaked. It can be structured differently and has instructions Basis weight from 30 to 50 g / qm.
Außer der Schicht aus Papier oder Glasfasergewebe können auch Schichten aus Filz Stoff, Steinwolle oder Hartfaser eingesetzt werden.In addition to the layer of paper or fiberglass, layers of felt can also be used Fabric, rock wool or hard fiber can be used.
Zwecks Vereinfachung der Herstellung der Brandschutzlaminate verwendet man die Folien bzw. Schichten aus unbehandelten Glasfasergewebe, Papier, Stoff oder Filz in Verbundform, wie sie auch im Handel erhältlich sind. Der Aufbau der Verbundfolien kann dabei unterschiedlich sein. Im einfachsten Fall ist eine Kunststoffolie zusammen mit einer Papierschicht kaschiert. Höheren Ansprüchen genügt demgegenüber eine Verbundfolie, bei der zwischen zwei Kunststoffolien eine Aluminiumfolie verklebt ist und die Kunststoffolien auf den Außenflächen mit einer Papierschicht, dem Glasfasergewebe, einer Schicht aus Stoff, Filz und/oder Steinwolle bzw. der Hartfaser beschichtet sind.To simplify the manufacture of fire protection laminates, the Sheets or layers of untreated glass fiber, paper, fabric or felt in Composite form, as they are also commercially available. The structure of the composite films can be different. In the simplest case is a plastic film laminated together with a layer of paper. Higher demands are sufficient in contrast, a composite film, in which between two plastic films Aluminum foil is glued and the plastic films on the outer surfaces with a Layer of paper, the glass fiber fabric, a layer of fabric, felt and / or Rock wool or hard fiber are coated.
Die Verbundfolie wird mit der Brandschutzschicht mit einer Natriumsilikatlösung verklebt. Hierbei kann man dieselbe Natriumsilikatlösung verwenden wie die zur Herstellung der Brandschutzschicht. Anstelle von Natriumsilikat kann die Verklebung aber auch mit einem organischen Kleber erfolgen. Epoxidharzkleber und solche aus Polyester haben sich dabei gut bewährt. Solche Kunststoffkleber besitzen zusätzliche Isoliereigenschaften gegenüber der Brandschutzschicht, so daß die Aluminiumfolie vom Natriumsilikat nicht angegriffen werden kann, auch wenn die sonst schützende Kunststoffolie fehlen würde. The composite film is covered with the fire protection layer with a sodium silicate solution glued. Here you can use the same sodium silicate solution as that for Production of the fire protection layer. Instead of sodium silicate, the Gluing can also be done with an organic adhesive. Epoxy resin adhesive and those made of polyester have proven themselves well. Such plastic glue have additional insulating properties compared to the fire protection layer, so that the aluminum foil cannot be attacked by the sodium silicate, even if the otherwise protective plastic film would be missing.
Sofern die Stirnflächen der Brandschutzlaminate offenliegen, kann von dieser offenen Seite die mit Natriumsilikat getränkte Fasermatte von Wasser und Kohlendioxid angegriffen werden. Gegen diesen unerwünschten Angriff verwendet man solche Brandschutzlaminate, deren Stirnflächen durch die Verbundfolie verschweißt oder verklebt sind.If the end faces of the fire protection laminates are exposed, this can be done open side the fiber mat of water and soaked with sodium silicate Carbon dioxide can be attacked. Used against this unwanted attack such fire protection laminates, their end faces through the composite film are welded or glued.
In den Abb. 1 bis 10 sind einige Beispiele der erfindungsgemäßen Brandschutzlaminate dargestellt. Figures 1 to 10 show some examples of the fire protection laminates according to the invention.
In Abb. 1 ist die mit einem Natriumsilikat beschichtete Fasermatte A zunächst beidseitig mit einer Papierschicht B umgeben. Daran schließt sich wiederum beidseitig eine Polyethylenfolie C an. Dann folgt je eine Aluminiumfolie D auf beiden Seiten, die wiederum von einer weiteren Polyethylenfolie C abgedeckt wird. Die Verbundfolie besteht hier also aus den Schichten B, C, D und C, also aus einer Papierschicht, einer Kunststoffolie, einer Aluminiumfolie und wiederum einer Kunststoffolie.In Fig. 1, the fiber mat A coated with a sodium silicate is initially surrounded on both sides with a paper layer B. This is in turn followed by a polyethylene film C on both sides. This is followed by an aluminum foil D on both sides, which in turn is covered by another polyethylene foil C. The composite film here consists of layers B, C, D and C, i.e. a paper layer, a plastic film, an aluminum film and again a plastic film.
Die Verbundfolien der Abb. 2 weisen eine zusätzliche Papierschicht B′ an den Außenflächen auf.The composite films of Fig. 2 have an additional paper layer B 'on the outer surfaces.
Abb. 3 und 4 sehen Brandschutzlaminate vor, die Ähnlichkeiten mit den Laminaten von Abb. 2 und 3 aufweisen. Anstelle der Papierschicht B in der Verbundfolie der Abb. 1 und 2 wird hier ein unbehandeltes Glasfasergewebe E verwendet, so daß die Schichtenfolge in der Verbundfolie hier E, C, D, C bzw. E, C, D, C, B′ lautet. Anstelle des Glasfasergewebes E kann hier eine Schicht aus Filz, Stoff, Hartfaser oder Steinwolle verwendet werden. Fig. 3 and 4 provide fire protection laminates that are similar to the laminates of Fig. 2 and 3. Instead of the paper layer B in the composite film of Figs. 1 and 2, an untreated glass fiber fabric E is used here, so that the layer sequence in the composite film here is E, C, D, C or E, C, D, C, B '. Instead of the glass fiber fabric E, a layer of felt, fabric, hard fiber or rock wool can be used.
Weitere Ausführungsbeispiele zeigen die Abb. 5 und 6. Die Besonderheit dieser Laminate besteht darin, daß die Verbundfolien über die mit Natriumsilikat getränkte Fasermatte A hinausragen. Bei dieser Laminatkonstruktion können die überstehenden Verbundfolien miteinander verschweißt oder verklebt werden, um auf diese Weise die Brandschutzlaminate noch besser gegen Feuchtigkeit und Kohlendioxid zu schützen. FIGS. 5 and 6 show further exemplary embodiments . The special feature of these laminates is that the composite films protrude beyond the fiber mat A impregnated with sodium silicate. With this laminate construction, the protruding composite films can be welded or glued to one another in order to protect the fire protection laminates even better against moisture and carbon dioxide.
Werden die erfindungsgemäßen Brandschutzlaminate in solchen Hohlräumen verwendet, die von sich aus genügend Schutz gegen Wasser und Kohlendioxid bieten, so können einfachere Laminate, wie in Abb. 7 dargestellt, eingesetzt werden. Sie bestehen lediglich aus der mit Natriumsilikat getränkten Fasermatte A und je einer Verbundfolie aus Papier B und der Kunststoffolie C. Gelagert und transportiert sollten solche Laminate zwecks besserer Haltbarkeit in wasserdichten Folien, die zusätzlich einen Schutz gegenüber Kohlendioxid gewährleisten. Als Folienmaterial empfiehlt sich hier eine Verbundfolie aus Aluminium beidseitig beschichtet mit einem Kunststoff, wie Polyethylen oder Polyester.If the fire protection laminates according to the invention are used in cavities which in themselves offer sufficient protection against water and carbon dioxide, simpler laminates, as shown in Fig. 7, can be used. They only consist of the fiber mat A soaked with sodium silicate and a composite film made of paper B and the plastic film C. Such laminates should be stored and transported for better durability in waterproof films that also provide protection against carbon dioxide. A composite film made of aluminum coated on both sides with a plastic such as polyethylene or polyester is recommended as the film material.
In den Abb. 8 bis 10 sind Brandschutzlaminate schematisch dargestellt, deren Brandschutzschicht A beidseitig mit einem organischen Kleber F mit je einer Verbundfolie verbunden ist. Wegen der Isolierfähigkeit der Klebstoffschicht wurde in Abb. 9 auf den Einsatz einer Aluminiumfolie verzichtet. Figs. 8 to 10 show fire protection laminates, whose fire protection layer A is bonded on both sides with an organic adhesive F with a composite film. Due to the insulating ability of the adhesive layer, the use of an aluminum foil was omitted in Fig. 9.
Die Brandschutzlaminate können zusätzlich auf einer oder auch auf beiden Seiten eine Selbstklebeschicht aufweisen, die durch eine Kunststoffolie abgedeckt ist. Bei Anwendung solcher Brandschutzlaminate wird diese Kunststoffolie entfernt und das Laminat auf die zu schützende Fläche geklebt. The fire protection laminates can additionally on one or both sides have a self-adhesive layer which is covered by a plastic film. At Using such fire protection laminates, this plastic film is removed and that Glued laminate on the surface to be protected.
Die Brandschutzlaminate besitzen in der Regel eine Dicke von 1,6 bis 4,0 mm, vorzugsweise 1,6 bis 2,4 mm. Wegen ihrer geringen Dicke sind sie zwischen 20 und 40°C flexibel und somit leicht zu handhaben. Ihr Flächengewicht liegt vorzugsweise bei 3 bis 3,5 Kg/qm und bei 6 Kg/qm bei einer Dicke von 4 mm.The fire protection laminates usually have a thickness of 1.6 to 4.0 mm, preferably 1.6 to 2.4 mm. Because of their small thickness, they are between 20 and 40 ° C flexible and therefore easy to use. Your basis weight is preferably at 3 to 3.5 kg / m2 and at 6 kg / m2 with a thickness of 4 mm.
Über 40°C wird das Brandschutzlaminat plastisch und beginnt bei etwa 100°C zu schäumen, wobei eine nichtbrennbare, feinporige, hitzedämmende und druckstabile Schaumschicht von etwa 15 bis 30 mm entsteht.The fire protection laminate becomes plastic above 40 ° C and starts at around 100 ° C foam, being a non-flammable, fine-pored, heat-insulating and pressure-stable Foam layer of about 15 to 30 mm is created.
Diese Schaumschicht macht es erforderlich, die Brandschutzlaminate so zwischen zwei Bauteilen so zu plazieren, daß noch genügend Raum für das gegebenenfalls entstehende Schaumvolumen vorhanden ist, zumal der entstehende Blähdruck Werte von 1,5 N/qmm annehmen kann.This foam layer makes it necessary to sandwich the fire protection laminates to place two components so that there is still enough space for the if necessary resulting foam volume is present, especially since the resulting expansion pressure values of 1.5 N / qmm.
Die Wärmeleitfähigkeit der nicht geschäumten Platte liegt bei etwa 0,8 W/mK, im geschäumten Zustand bei 0,06 W/mK.The thermal conductivity of the non-foamed sheet is about 0.8 W / mK, in foamed state at 0.06 W / mK.
Diese aufgeführten Eigenschaften verleihen der erfindungsgemäßen Brandschutzplatte eine Feuerwiderstandsdauer gemäß DIN 4102 von über 30 Minuten, ohne daß bei den hohen Temperaturen ökologisch bedenkliche oder gesundheitsschädliche Dämpfe entstehen.These properties give the invention Fire protection plate has a fire resistance duration according to DIN 4102 of over 30 Minutes without being ecologically questionable at the high temperatures Harmful vapors are generated.
