Description
Aufschäumbares BrandschutzlaminatExpandable fire protection laminate
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 1169832 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 Oberzug aus wasserunlöslichem Material.The invention relates to a fire protection laminate which foams at higher temperatures and thus provides protection against the effects of fire. Flame protection layers using fibers soaked in alkali silicate are known. For example, DE-AS 1169832 describes a process for producing thermally insulating flame protection layers in which inorganic and/or synthetic organic fibers or fabrics made from them are provided with a layer of an alkali silicate solution. These layers are solidified by drying. Such layers are given a coating of water-insoluble material to protect them against the harmful effects of water.
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 no longer meet the requirements placed on them. For example, they lose the ability to foam up in the event of a fire under the influence of carbon dioxide. The task was therefore to improve fire protection laminates of the type described so that they remain stable against the influence of water and carbon dioxide over longer periods of time and thus retain their protective function. This is particularly true in cases where subsequent access to the fire protection laminates is no longer possible after they have been installed.
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 contain ecologically harmless materials and should not develop any toxic substances in the event of a fire. Questionable materials, such as plastic films containing chlorine, should be excluded from their production.
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 new fire protection laminates should be manufactured as simply as possible, with changes to the materials used, especially the composite films, having as little impact on the manufacturing process as possible.
Zur Lösung dieser Aufgabe werden Brandschutzlaminate entsprechend Anspruch vorgeschlagen. Bevorzugte Laminate sind in den Unteransprüchen beschrieben.To solve this problem, fire protection laminates according to claim are proposed. 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 11 832. 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 is a fire protection layer treated with a sodium silicate solution. It is produced in a generally known manner, e.g. according to the process of DE-AS 11 832. A mat made of glass fiber, rock wool or the like is treated with a sodium silicate solution and most of the water is removed at an elevated temperature without the mat to be dried swelling. The water must not be completely removed 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, ordinary water glass can be used as a sodium silicate solution. Additives such as silicon dioxide, talcum, titanium dioxide, etc. or wetting agents, as also described in DE-AS 11 69 832, result in improved products. The finished fire protection layer has a thickness of 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 &mgr;&eegr;&igr;, insbesondere von 12 &mgr;&pgr;&igr;.The films used can be made of any polymeric material. Preference is given to polyethylene, polypropylene, polyamide, polyester or an ionomer. The aluminum foils used are those with a thickness of 9 to 20 μηι, especially 12 μηι.

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 unterschiedlieh strukturiert sein und weist ein Flächengewicht von 30 bis 50 g/qm auf.Any type of paper can be used as paper layers. Soda kraft paper with a minimum weight of 20 g/m² has proven to be particularly advantageous. Instead of paper, a glass fiber fabric can also be used which, unlike the fiber mat already described, is not impregnated with silicate in the laminate. It can have different structures and has a basis weight of 30 to 50 g/m².
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 glass fibre fabric, layers of felt, fabric, rock wool or hard fibre can also 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 production of fire protection laminates, the films or layers made of untreated glass fiber fabric, paper, fabric or felt are used in a composite form, as they are also commercially available. The structure of the composite films can vary. In the simplest case, a plastic film is laminated together with a paper layer. Higher demands are met by a composite film in which an aluminum foil is glued between two plastic films and the plastic films are coated on the outer surfaces with a paper layer, the glass fiber fabric, a layer of fabric, felt and/or rock wool or hard fiber.
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 bonded to the fire protection layer using a sodium silicate solution. The same sodium silicate solution can be used here as that used to make the fire protection layer. Instead of sodium silicate, the bonding can also be done using an organic adhesive. Epoxy resin adhesives and those made from polyester have proven to be very effective. Such plastic adhesives 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 is missing.
Sofern die Stirnflächen der Brandschutzlaminate offenliegen, kann von dieser offenen Seite die mit Natriumsilikat getränkte Pasermatte 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 front surfaces of the fire protection laminates are exposed, the fiber mat impregnated with sodium silicate can be attacked by water and carbon dioxide from this open side. To counteract this undesirable attack, fire protection laminates are used whose front surfaces are welded or glued by the composite film.
In den Abbildungen 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 Abbildung 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,G,D und C, also aus einer Papierschicht, einer Kunststoffolie, einer Aluminiumfolie und wiederum einer Kunststoffolie.In Figure 1, the fiber mat A coated with a sodium silicate is initially surrounded on both sides by a paper layer B. This is then followed by a polyethylene film C on both sides. Then there is an aluminum film D on both sides, which in turn is covered by another polyethylene film C. The composite film here therefore consists of layers B, G, D and C, i.e. a paper layer, a plastic film, an aluminum film and again a plastic film.
Die Verbundfolien der Abbildung 2 weisen eine zusätzliche Papierschicht B1 an den Außenflächen auf.The composite films in Figure 2 have an additional paper layer B 1 on the outer surfaces.
Abbildung 3 und 4 sehen Brandschutzlaminate vor, die Ähnlichkeiten mit den Laminaten von Abbildung 2 und 3 aufweisen. Anstelle der Papierschicht B in der Verbundfolie der Abbildungen 1 und 2 wird hier ein unbehandeltes Glasfasergewebe E verwendet, so daß die Schichtenfolge in der Verbundfolie hier E,C,D,C bzw. B,C,D,C,B1 lautet. Anstelle des Glasfasergewebes E kann hier eine Schicht aus Pilz, Stoff, Hartfaser oder Steinwolle verwendet werden.Figures 3 and 4 show fire protection laminates that are similar to the laminates in Figures 2 and 3. Instead of the paper layer B in the composite film in Figures 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 B,C,D,C,B 1. Instead of the glass fiber fabric E, a layer of mushroom, fabric, hard fiber or rock wool can be used here.
Weitere Ausführungsbeispiele zeigen die Abbildungen 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.Further examples are shown in Figures 5 and 6. The special feature of these laminates is that the composite films protrude beyond the fiber mat A impregnated with sodium silicate. In this laminate construction, the protruding composite films can be welded or glued together 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 Abbildung 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 that offer sufficient protection against water and carbon dioxide, simpler laminates can be used, as shown in Figure 7. They consist only of the fiber mat A soaked in sodium silicate and a composite film made of paper B and plastic film C. For better durability, such laminates should be stored and transported 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 Abbildungen 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 Abbildung 9 auf den Einsatz einer Aluminiumfolie verzichtet.Figures 8 to 10 show schematic representations of fire protection laminates, whose fire protection layer A is bonded on both sides to a composite foil using an organic adhesive F. Due to the insulating properties of the adhesive layer, the use of aluminum foil was omitted in Figure 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 also have a self-adhesive layer on one or both sides, which is covered by a plastic film. When using such fire protection laminates, this plastic film is removed and the laminate is glued to the surface to be protected.
Die Brandschutzlamxnate 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 0C 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 low thickness, they are flexible between 20 and 40 ° C and therefore easy to handle. Their weight per unit area is preferably 3 to 3.5 kg/m² and 6 kg/m² for a thickness of 4 mm.
Über 40 0C wird das Brandschutzlaminat plastisch und beginnt bei etwa 100 0C zu schäumen, wobei eine nichtbrennbare, feinporige, hitzedämmende und druckstabile Schaumschicht von etwa 15 bis 30 mm entsteht.Above 40 ° C, the fire protection laminate becomes plastic and begins to foam at around 100 ° C, creating a non-flammable, fine-pored, heat-insulating and pressure-stable foam layer of around 15 to 30 mm.
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 place the fire protection laminates between two components in such a way that there is still enough space for the foam volume that may arise, especially since the resulting expansion pressure can reach values of 1.5 N/mm2.
Die Wärmekeitfähigkeit 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 panel is approximately 0.8 W/mK, while in the foamed state it is 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 fire protection panel according to the invention a fire resistance period of more than 30 minutes in accordance with DIN 4102, without the high temperatures giving rise to ecologically harmful or health-damaging fumes.
