Definitions
- the invention relates to a fire protection plate made of a core layer and outer layers impregnated with an expandable material.
- Fire protection panels and elements are used wherever the passage of fire and the transfer of heat are to be prevented in the event of a fire.
- An effective means of preventing the passage of fire and heat are so-called “intumescent” materials, which in the event of fire, i.e. Inflate at temperatures above 100 ° C, forming a heat-resistant and heat-insulating foam.
- Fire protection elements are known from EP-A-123 255, in which the carrier material of the core layer is inorganic and preferably consists of mineral fibers which are impregnated with an intumescent agent. Such fire protection elements require either metallic or relatively thick non-metallic cover layers and stiffening profiles, which give them the necessary flexural strength. Fire doors made from it are therefore very heavy.
- the invention was based on the object of developing light, easy-to-produce fire protection boards with good flexural strength, which have a high fire resistance in the event of a fire.
- a fire protection plate made of outer layers B and a core layer A, which consists of a predominantly organic, open-cell material A1, which is at least partially impregnated with a heat-expandable mass A2, which is predominantly inside the core layer.
- the core layer A has a thickness of 2 to 200 mm, preferably 15 to 100 mm.
- the open-cell material A1 honeycomb or foam structure and contains - before impregnation with the intumescent mass A2 - 80 to 99 percent by volume voids.
- the honeycombs can be made of cardboard or plastic, e.g. exist on the basis of thermosetting resins or polyurethane.
- open-cell plastic foams are those made of thermosets, e.g. Melamine, urea or phenolic resins or polyurethane are suitable.
- the open-cell material A 1 consists of bound organic fibers, chips or chips and contains - before impregnation - 2 to 30 volume percent voids.
- Preferred material A1 are cement or synthetic resin-bound wood shavings, wood wool or wood fiber masses.
- the open-cell material A1 is impregnated with an intumescent mass A2, which inflates in the event of a fire.
- compositions foam at temperatures above 100 ° C, especially above 150 ° C. They form a largely closed-cell foam with low thermal conductivity, which prevents the passage of oxygen and heat and is therefore fire-resistant and heat-insulating. It is essential that the mass A2 is predominantly, preferably practically completely, impregnated inside the core layer, ie in the cavities. It is of course not excluded that a thin layer is still on the surface, which in some cases can also be used for gluing to the cover layers B. However, it is not necessary that the mass A2 is evenly distributed over the thickness of the open-cell material A1 and completely soaked it. In many cases it is sufficient if only the edge areas of the core layer are impregnated with the mass A2.
- the core layer contains the mass A2 in an amount of 20 to 300 g of solid per liter of total volume.
- the impregnation can be carried out by customary methods, for example by immersion, spraying, pouring or rolling in the aqueous solutions of the mass A2.
- the cover layers B can be 0.5 to 10, preferably 0.8 to 8 mm thick. They serve stability and decoration purposes and can e.g. consist of wood, bonded wood materials, metal, plastics, glass, ceramics or fiber-reinforced materials.
- the fire protection plate is designed as a multiple sandwich with one or more intermediate layers made of material B. If a core layer has burned away or has come off during prolonged exposure to fire protection, the next layers still form an intact cross-section with high bending strength and rigidity.
- Core layer and cover layers are made in the usual way, e.g. bonded together with phenolic, melamine, polyurethane or latex-based adhesives.
- the fire protection panels according to the invention can be used in construction, in vehicle, ship and aircraft construction, and as storage and transport containers, preferably as doors, gates, partitions, floors and ceilings.
- a 25 mm thick core layer of cardboard honeycombs (36 g / l, 95% by volume voids) was made with an amount of 120 g / l solids in an aqueous solution of 11 parts urea, 14 parts dicyandiamide, 23 parts ammonium hydrogen orthophosphate, 14 parts formaldehyde, 6 Parts of dextrin and 32 parts of water impregnated by immersion.
- the core layer was connected on both sides with the aid of a phenol / resorcinol / formaldehyde resin-based adhesive to two 3.8 mm thick hard fiber cover layers.
- the fire resistance time of the fire protection plate (load according to the standard temperature curve according to ISO 834) until it burned through was 32 min; in the case of a comparison plate which was not impregnated with the expandable mass, the fire resistance duration was only 12 min.
- a 25 mm thick core layer of melamine resin foam with a density of 11 g / l and a pore volume of 99% was impregnated by spraying with 155 g / l solids content of an expandable mass as in Example 1 and bonded to two 1.0 mm cover layers made of sheet steel.
- the fire resistance period (time until the temperature rose to 140 ° C on the non-flamed side) was 30 min; with a comparison plate only 13 min.

Abstract
Description
Die Erfindung betrifft eine Brandschutzplatte aus einer mit einer blähfähigen Masse imprägierten Kernschicht und Deckschichten.The invention relates to a fire protection plate made of a core layer and outer layers impregnated with an expandable material.
Brandschutzplatten und -elemente werden überall dort angewandt, wo im Brandfall der Durchtritt des Feuers und die Übertragung von Hitze unterbunden werden soll. Ein wirksames Mittel zur Verhinderung des Durchtritts von Feuer und Hitze sind sogenannte "intumeszierende" Materialien, die im Brandfall, d.h. bei Temperaturen oberhalb von 100°C, aufblähen, wobei sie einen hitzebeständigen und wärmeisolierenden Schaum bilden.Fire protection panels and elements are used wherever the passage of fire and the transfer of heat are to be prevented in the event of a fire. An effective means of preventing the passage of fire and heat are so-called "intumescent" materials, which in the event of fire, i.e. Inflate at temperatures above 100 ° C, forming a heat-resistant and heat-insulating foam.
Es ist bekannt, Holztüren mit derartigem Material zu beschichten, wobei auch geringe Anteile in die Holzoberfläche eindringen können. Solche Brandschutztüren weisen jedoch keine ausreichende Feuerwiderstandsdauer auf, bzw. müssen mit derart hohen Mengen an Brandschutzmaterial beschichtet werden, daß die im Brandfall entstehende Schaumschicht und damit verklebte Deckschichten nach relativ kurzer Zeit abfallen.It is known to coat wooden doors with such material, and even small proportions can penetrate into the wooden surface. However, such fire protection doors do not have a sufficient fire resistance period, or must be coated with such high amounts of fire protection material that the foam layer which arises in the event of fire and the cover layers bonded to it fall off after a relatively short time.
Aus der EP-A-123 255 sind Brandschutzelemente bekannt, bei denen das Trägermaterial der Kernschicht anorganischer Natur ist und vorzugsweise aus Mineralfasern besteht, welche mit einem intumeszierenden Mittel imprägniert sind. Solche Brandschutzelemente benötigen entweder metallische oder verhältnismäßig dicke nichtmetallische Deckschichten und Aussteifungsprofile, die ihnen die notwendige Biegefestigkeit verleihen. Daraus hergestellte Brandschutztüren sind daher sehr schwer.Fire protection elements are known from EP-A-123 255, in which the carrier material of the core layer is inorganic and preferably consists of mineral fibers which are impregnated with an intumescent agent. Such fire protection elements require either metallic or relatively thick non-metallic cover layers and stiffening profiles, which give them the necessary flexural strength. Fire doors made from it are therefore very heavy.
Der Erfindung lag nun die Aufgabe zugrunde, leichte, einfach herzustellende Brandschutzplatten mit guter Biegefestigkeit zu entwickeln, die im Brandfall eine hohe Feuerwiderstandsdauer aufweisen.The invention was based on the object of developing light, easy-to-produce fire protection boards with good flexural strength, which have a high fire resistance in the event of a fire.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Brandschutzplatte aus Deckschichten B und einer Kernschicht A, die aus einem überwiegend organischen, offenzelligen Material A₁ besteht, welches zumindest teilweise mit einer hitzeblähfähigen Masse A₂ imprägniert ist, die sich überwiegend im Innern der Kernschicht befindet.This object is achieved by a fire protection plate made of outer layers B and a core layer A, which consists of a predominantly organic, open-cell material A₁, which is at least partially impregnated with a heat-expandable mass A₂, which is predominantly inside the core layer.
Es ist überraschend, daß derartige Platten auf Basis eines Trägermaterials, das organischer Natur und somit brennbar ist, eine Feuerwiderstandsdauer aufweisen, die zumindest nicht wesentlich geringer als bei anorganischen Trägermaterialien ist. Gegenüber Platten mit Mineralwolle als Trägermaterial weisen die erfindungsgemäßen Platten eine bessere Biegesteifigkeit auf, da die Kernschicht durch ihre Schubsteifigkeit und den Verbund mit den festen Deckschichten bei Biegebelastung des Verbunds mechanisch mitträgt.It is surprising that such boards based on a carrier material which is organic in nature and therefore flammable have a fire resistance duration which is at least not significantly less than that of inorganic carrier materials. Compared to boards with mineral wool as the carrier material, the boards according to the invention have better flexural rigidity, since the core layer is due to its shear rigidity and mechanically supports the bond with the solid cover layers when the bond is subjected to bending loads.
Die Kernschicht A hat eine Dicke von 2 bis 200 mm, vorzugsweise von 15 bis 100 mm. Bei einer bevorzugten Ausführungsform weist das offenzellige Material A₁ Waben- oder Schaumstruktur auf und enthält - vor der Imprägnierung mit der intumeszierenden Masse A₂ - 80 bis 99 Volumenprozent Hohlräume. Die Waben können dabei aus Pappe oder Kunststoff, z.B. auf Basis von Duromerharzen oder Polyurethan bestehen. Als offenzellige Kunststoff-Schäume sind solche aus Duromeren, z.B. Melamin-, Harnstoff- oder Phenolharzen oder Polyurethan geeignet.The core layer A has a thickness of 2 to 200 mm, preferably 15 to 100 mm. In a preferred embodiment, the open-cell material A₁ honeycomb or foam structure and contains - before impregnation with the intumescent mass A₂ - 80 to 99 percent by volume voids. The honeycombs can be made of cardboard or plastic, e.g. exist on the basis of thermosetting resins or polyurethane. As open-cell plastic foams are those made of thermosets, e.g. Melamine, urea or phenolic resins or polyurethane are suitable.
Bei einer anderen bevorzugten Ausführungsform besteht das offenzellige Material A₁ aus gebundenen organischen Fasern, Schnitzeln oder Spänen und enthält - vor der Imprägnierung - 2 bis 30 Volumenprozent Hohlräume. Bevorzugtes Material A₁ sind zement- oder kunstharzgebundene Holzspan-, Holzwolle- oder Holzfasermassen.In another preferred embodiment, the open-cell material A 1 consists of bound organic fibers, chips or chips and contains - before impregnation - 2 to 30 volume percent voids. Preferred material A₁ are cement or synthetic resin-bound wood shavings, wood wool or wood fiber masses.
Das offenzellige Material A₁ ist mit einer intumeszierenden Masse A₂ imprägniert, die im Brandfall aufbläht. Dafür kommen insbesondere die bekannten Massen auf Basis wäßriger Lösungen von Amin/Formaldehyd-Kondensationsprodukten in Frage, wie Harnstoff- oder Dicyandiamid/Formaldehyd-Kondensate, die weitere Zusätze, wie Kohlehydrate, Phosphate und Alkohole (z.B. nach DE-B-23 15 416) enthalten können, ferner wasserhaltige Alkalisilikate (z.B. nach AT-B-237 501).The open-cell material A₁ is impregnated with an intumescent mass A₂, which inflates in the event of a fire. In particular, the known compositions based on aqueous solutions of amine / formaldehyde condensation products, such as urea or dicyandiamide / formaldehyde condensates, the further additives, such as carbohydrates, phosphates and alcohols (for example according to DE-B-23 15 416) may contain, furthermore water-containing alkali silicates (for example according to AT-B-237 501).
Derartige Massen schäumen bei Temperaturen oberhalb von 100°C, insbesondere oberhalb von 150°C. Sie bilden dabei einen weitgehend geschlossenzelligen Schaum mit geringer thermischer Leitfähigkeit, der den Durchtritt von Sauerstoff und Hitze verhindert und somit feuerbeständig und wärmeisolierend ist. Es ist wesentlich, daß die Masse A₂ überwiegend, vorzugsweise praktisch vollständig, im Innern der Kernschicht, d.h. in deren Hohlräumen imprägniert ist. Dabei ist selbstverständlich nicht ausgeschlossen, daß sich eine dünne Schicht noch an der Oberfläche befindet, die in manchen Fällen auch zum Verkleben mit den Deckschichten B dienen kann. Es ist jedoch nicht notwendig, daß die Masse A₂ gleichmäßig über die Dicke des offenzelligen Materials A₁ verteilt ist und dieses vollständig durchtränkt. In vielen Fällen genügt es, wenn nur die Randbereiche der Kernschicht mit der Masse A₂ imprägniert sind. Im allgemeinen enthält die Kernschicht die Masse A₂ in einer Menge von 20 bis 300 g Feststoff pro l Gesamtvolumen. Das Imprägnieren kann nach üblichen Methoden, z.B. durch Eintauchen, Aufspritzen, Aufgießen oder Einrollen der wäßrigen Lösungen der Masse A₂ vorgenommen werden.Such compositions foam at temperatures above 100 ° C, especially above 150 ° C. They form a largely closed-cell foam with low thermal conductivity, which prevents the passage of oxygen and heat and is therefore fire-resistant and heat-insulating. It is essential that the mass A₂ is predominantly, preferably practically completely, impregnated inside the core layer, ie in the cavities. It is of course not excluded that a thin layer is still on the surface, which in some cases can also be used for gluing to the cover layers B. However, it is not necessary that the mass A₂ is evenly distributed over the thickness of the open-cell material A₁ and completely soaked it. In many cases it is sufficient if only the edge areas of the core layer are impregnated with the mass A₂. In general, the core layer contains the mass A₂ in an amount of 20 to 300 g of solid per liter of total volume. The impregnation can be carried out by customary methods, for example by immersion, spraying, pouring or rolling in the aqueous solutions of the mass A₂.
Die Deckschichten B können 0,5 bis 10, vorzugsweise 0,8 bis 8 mm dick sein. Sie dienen Stabilitäts- und Dekorationszwecken und können z.B. aus Holz, gebundenen Holzwerkstoffen, Metall, Kunststoffen, Glas, Keramik oder faserarmierten Massen bestehen.The cover layers B can be 0.5 to 10, preferably 0.8 to 8 mm thick. They serve stability and decoration purposes and can e.g. consist of wood, bonded wood materials, metal, plastics, glass, ceramics or fiber-reinforced materials.
Bei einer besonderen Ausführungsform der Erfindung ist die Brandschutzplatte als Mehrfachsandwich mit einer oder mehreren Zwischenschichten aus dem Material B ausgebildet. Wenn bei länger andauernder Brandschutzbelastung eine Kernschicht weggebrannt ist oder sich abgelöst hat, bilden die nächsten Schichten immer noch einen intakten Verbundquerschnitt mit hoher Biegefestigkeit und -steifigkeit.In a special embodiment of the invention, the fire protection plate is designed as a multiple sandwich with one or more intermediate layers made of material B. If a core layer has burned away or has come off during prolonged exposure to fire protection, the next layers still form an intact cross-section with high bending strength and rigidity.
Kernschicht und Deckschichten werden auf übliche Weise, z.B. mit Klebern auf Phenolharz-, Melaminharz-, Polyurethan- oder Latex-Basis miteinander verbunden.Core layer and cover layers are made in the usual way, e.g. bonded together with phenolic, melamine, polyurethane or latex-based adhesives.
Die erfindungsgemäßen Brandschutzplatten können im Bauwesen, im Fahrzeug-, Schiffs- und Flugzeugbau, sowie als Lager- und Transport-Behälter Verwendung finden, bevorzugt als Türen, Tore, Trennwände, Böden und Decken.The fire protection panels according to the invention can be used in construction, in vehicle, ship and aircraft construction, and as storage and transport containers, preferably as doors, gates, partitions, floors and ceilings.
