Description

Wärmedämmverbund mit verbesserter Thermostabilität und verbessertem BrandverhaltenThermal insulation composite with improved thermal stability and improved fire behavior
Beschreibungdescription
Die Erfindung betrifft einen Wärmedämmverbund, umfassend zwei Metallplatten mit einem wärmedämmenden Kernmaterial, wobei zwischen dem wärmedämmenden Kernmaterial und mindestens einer der Metallplatten eine Brandschutzschicht eingebracht ist, Verfahren zu dessen Herstellung sowie Verwendung zur Herstellung von Lager- oder Kühlhallen.The invention relates to a thermal insulation composite, comprising two metal plates with a heat-insulating core material, a fire protection layer being introduced between the heat-insulating core material and at least one of the metal plates, method for its production and use for the production of storage or cooling halls.
Sandwich-Panels aus einem wärmedämmenden Kernmaterial und beidseitig verklebten Stahl- oder Aluminiumplatten werden als Konstruktionselemente oder Verkleidung in Bauanwendungen eingesetzt. Ihre thermische Stabilität im Falle eines Brandes ist vielfach nicht ausreichend. So können im Brandfalle schon aufgrund der Hitzeeinwirkung thermoplastische Schaumstoffe zusammenschmelzen und die mechanische Stabilität der Sandwich-Panels beeinträchtigen.Sandwich panels made of a heat-insulating core material and steel or aluminum plates glued on both sides are used as construction elements or cladding in construction applications. Their thermal stability in the event of a fire is often not sufficient. In the event of a fire, thermoplastic foams can melt together due to the effects of heat and impair the mechanical stability of the sandwich panels.
Die WO 02/064672 schlägt daher vor, als Kernmaterial einen Polymerschaumstoff mit einer kontinuierlichen Phase aus einem Phenol-Harz und dispergierten Polystyrolschaumstoffpartikeln zu verwenden.WO 02/064672 therefore proposes to use a polymer foam with a continuous phase made of a phenol resin and dispersed polystyrene foam particles as the core material.
Aus der GB-A 2362586 ist ein Verfahren zur Verbesserung des Flammschutzes von Polystyrolschaumstoffblöcken beschrieben, bei dem die vorgeschäumten Polystyol- schaumstoffpartikel mit einem flüssigen Phenolharz, welches ein Flammschutzmittel auf Basis von Phosphor oder Chorverbindungen enthält, beschichtet und anschießend zu Blöcken verschweißt werden. Derartige flammgeschützte Polystyrolschaumstoffblöcke können bei Einwirkung von höheren Temperaturen über längere Zeit jedoch wegschmelzen.GB-A 2362586 describes a process for improving the flame retardancy of polystyrene foam blocks, in which the prefoamed polystyrene foam particles are coated with a liquid phenolic resin, which contains a flame retardant based on phosphorus or chlorine compounds, and then welded into blocks. However, such flame-retardant polystyrene foam blocks can melt away over a long period of time when exposed to higher temperatures.
Aus der DE-A 19639842 sind brandgeschützte Verbundsysteme aus Polystyrolschaumstoffblöcken, die an der Oberfläche mit Profilen, Gittern oder Netzen versehen sind, welche mit einer intumeszierenen Masse getränkt wurden. Die Profile, Gitter oder Netze werden bevorzugt in die Fugen zwischen den Schaumstoffplatten eingebracht.DE-A 19639842 describes fire-protected composite systems made of polystyrene foam blocks which are provided on the surface with profiles, grids or nets which have been impregnated with an intumescent mass. The profiles, grids or nets are preferably introduced into the joints between the foam sheets.
Die EP-A 0942 107 beschreibt einen flammhemmend imprägnierten Schaumstoffkör- per aus im wesentlichen PU-Schaum, der mit zwei Selbstklebefolien, zwischen denen eine intumeszierendes Material eingeschlossen ist, kaschiert wird und dessen Verwendung als Brandschutzstopfen.EP-A 0942 107 describes a flame-retardant impregnated foam body made of essentially PU foam, which is laminated with two self-adhesive films, between which an intumescent material is enclosed, and its use as a fire stopper.
Aufgabe der vorliegenden Erfindung war es daher den genannten Nachteilen abzuhelfen und ein Wärmedämmverbund mit verbesserter Thermostabilität und verbessertem Brandverhalten sowie ein Verfahren zu dessen Herstellung zu finden. Demgemäss wurde der eingangs beschriebene Wärmedämmverbund gefunden. Die Metallplatten des Wärmedämmverbundes bestehen in der Regel aus Stahl oder Aluminium mit einer Dicke von 1 bis 10 mmThe object of the present invention was therefore to remedy the disadvantages mentioned and to find a thermal insulation composite with improved thermal stability and improved fire behavior and a process for its production. Accordingly, the thermal insulation composite described above was found. The metal plates of the thermal insulation composite usually consist of steel or aluminum with a thickness of 1 to 10 mm
Das wärmedämmende Kernmaterial kann aus Polystyrolpartikelschaumstoff, extrudier- ten Polystyrolschaumstoffplatten (XPS), Polyurethan- oder PIR-Schaumstoffen oder Mineralwolle bestehen. Aufgrund seiner geringen Dichte, Verarbeitbarkeit und langanhaltende Dämmvermögen wird bevorzugt ein wärmedämmendes Kernmaterial aus Polystyrolpartikelschaumstoffplatten, die durch Vereintem von vorgeschäumten Polystyrolschaumpartikeln aus expandierbarem Polystyrol (EPS) erhältlich sind. Bevorzugt werden Polystyrolpartikelschaumstoffplasten einer Dichte im Bereich von 10 bis 50 g/l und einer Dicke im Bereich von 50 bis 250 mm verwendet.The heat-insulating core material can consist of polystyrene particle foam, extruded polystyrene foam sheets (XPS), polyurethane or PIR foams or mineral wool. Because of its low density, processability and long-lasting insulation properties, a heat-insulating core material made of polystyrene particle foam sheets, which can be obtained by combining pre-expanded polystyrene foam particles made of expandable polystyrene (EPS), is preferred. Polystyrene particle foam plastics with a density in the range from 10 to 50 g / l and a thickness in the range from 50 to 250 mm are preferably used.
Die Brandschutzschicht kann als Laminat, Platte, Folie, Dispersion oder Lösung auf das Formteil aufgebracht werden. Die Dicke der Brandschutzschicht richtet sich nach dem verwendeten Material und liegt im allgemeinen im Bereich von 0,1 bis 50 mm, bevorzugt im Bereich von 1 bis 10 mm. Geeignet ist beispielsweise eine Schaumfolie aus einem thermisch resistenten Melaminharzschaum (z. B. Basotect®) oder ein Brandschutzlaminat aus gelierter Alkalisilikatlösung (z. B. Palusol®). Bevorzugt wird das wärmedämmende Kernmaterial mit einer intumeszierenden Masse beschichtet. Die Beschichtung kann durch Sprühen, Tauchen, Rollen oder Streichen auf einer oder mehreren Oberflächen des wärmedämmenden Kernmaterials aufgetragen werden. Das Beschichtungsmaterial selbst ist flammresistent. Dadurch wird das darunter lie- gende, thermisch sensitive Kernmaterial vor hohen Temperaturen und einen Übergriff der Flammen geschützt und behält seine strukturelle Integrität.The fire protection layer can be applied to the molding as a laminate, plate, film, dispersion or solution. The thickness of the fire protection layer depends on the material used and is generally in the range from 0.1 to 50 mm, preferably in the range from 1 to 10 mm. For example, a foam film made from a thermally resistant melamine resin foam (e.g. Basotect®) or a fire protection laminate made from gelled alkali silicate solution (e.g. Palusol®) is suitable. The heat-insulating core material is preferably coated with an intumescent material. The coating can be applied by spraying, dipping, rolling or brushing on one or more surfaces of the heat-insulating core material. The coating material itself is flame resistant. This protects the underlying, thermally sensitive core material from high temperatures and flame attack and maintains its structural integrity.
Als intumeszierende Massen werden Materialien bezeichnet, die bei Einwirkung höherer Temperaturen, in der Regel über 80 -100°C, aufschäumen und dabei einen isolie- renden und hitzebeständigen Schaum bilden, der das darunter liegende wärmedämmende Kernmaterial vor der Feuer- und Hitzewirkung schützt.Intumescent materials are materials that foam when exposed to higher temperatures, usually above 80-100 ° C, and form an insulating and heat-resistant foam that protects the underlying heat-insulating core material from the effects of fire and heat.
Bevorzugt enthält der Wärmedämmverbund als intumeszierende Masse ein Alkalisilikat, insbesondere ein wasserhaltiges Natriumsilikat, Blähgraphit oder Blähglimmer.The thermal insulation composite preferably contains an alkali silicate, in particular a water-containing sodium silicate, expanded graphite or expanded mica as intumescent material.
Der erfindungsgemäße Wärmedämmverbund kann durch Verbinden von zwei Metallplatten und einem wärmedämmenden Kernmaterial hergestellt werden, wobei zwischen dem wärmedämmenden Kernmaterial und mindestens einer Metallplatte, bevorzugt zwischen dem wärmedämmenden Kernmaterial und beiden Metallplatten, eine Brandschutzschicht eingebracht wird. Hierzu können kommerziell verfügbare Maschine zur Herstellung von Wärmedämmverbunden eingesetzt werden. Nach einem bevorzugten Verfahren wird das Kernmaterial auf mindestens einer Fläche des wärmedämmenden Kernmaterials mit einer intumeszierenden Masse beschichtet wird und anschließend mit den Metallplatten verklebt. Es ist auch möglich, die intumeszierende Masse mit dem Kleber zu vermischen, gemeinsam auf das Wärmedämmende Kernmaterial oder die Metallplatte zu geben oder eine intumeszierende Masse zu verwenden, die eine genügende Adhäsion zu der Metallplatte aufweist.The thermal insulation composite according to the invention can be produced by connecting two metal plates and a heat-insulating core material, a fire protection layer being introduced between the heat-insulating core material and at least one metal plate, preferably between the heat-insulating core material and both metal plates. For this purpose, commercially available machines for the production of thermal insulation bonds can be used. According to a preferred method, the core material is coated on at least one surface of the heat-insulating core material with an intumescent material and then glued to the metal plates. It is also possible to mix the intumescent mass with the adhesive, to put it together on the heat-insulating core material or the metal plate or to use an intumescent mass which has sufficient adhesion to the metal plate.
Als Klebstoffe können Ein- oder Zweikomponenten-Klebstoffe auf Basis von Polyurethan- oder Epoxidharzen eingesetzt werden. Es können aber auch Klebstoffe auf Dispersionsbasis, z. B Acrylatdispersionen (Acronal®) eingesetzt werden.One- or two-component adhesives based on polyurethane or epoxy resins can be used as adhesives. However, dispersion-based adhesives, e.g. B Acrylic dispersions (Acronal®) can be used.
In einer Ausführungsform wird die Brandschutzschicht ganz oder teilweise durch den Klebstoff gebildet. Hierzu werden dem Klebstoff Additive, wie Blähgraphit, wasserhaltige Natriumsilikate, Zinkborate, Melaminverbindungen, Metallhydroxide oder Metall- salzhydrate oder Mischungen davon, beigemischt. Der Anteil der Additive liegt im allgemeinen im Bereich von 2 bis 98 Gew.-%, bevorzugt 40 bis 90 Gew.-%, bezogen auf den Klebstoff. Zur Verbesserung der Verarbeitbarkeit, z. B. beim Streichen oder Sprühen, schnelleren Abtrocknung oder Verbesserung der Haftfestigkeit können dem Klebstoff weitere übliche Füllstoffe beigemischt werden.In one embodiment, the fire protection layer is wholly or partly formed by the adhesive. For this purpose, additives such as expanded graphite, water-containing sodium silicates, zinc borates, melamine compounds, metal hydroxides or metal salt hydrates or mixtures thereof are added to the adhesive. The proportion of additives is generally in the range from 2 to 98% by weight, preferably 40 to 90% by weight, based on the adhesive. To improve processability, e.g. B. when brushing or spraying, faster drying or improving the adhesive strength, other conventional fillers can be added to the adhesive.
In einer bevorzugten Ausführungsform wird die Brandschützschicht aus einer intumes- zierenen Masse auf Basis eines Natiumsilikates gebildet. Hierzu verwendet man eine handelsüblichen Wasserglaslösung mit einem Wassergehalt von ca. 65 Gew.-% und vermischt diese mit Wasserglaspulver mit einem Wassergehalt von ca. 18 Gew.-%. Die Gelierzeiten der Mischung lassen sich über die Menge an Wasserglaspulver gezielt einstellen. Gegebenenfalls können anorganische Füllstoffe wie Metallhydroxide oder Metallsulfat-Hydrate in Mengen von 0 bis 50 Gew. % sowie bis zu 10 Gew.-% organische Materialien dem Gemisch zugesetzt werden. Die flüssige Mischung kann direkt auf die Platten des Panel-Kernmaterials aufgetragen oder aufgesprüht werden. Die Schichtdicken der Beschichtung können dabei zwischen 0,05 und 5 mm variieren.In a preferred embodiment, the fire protection layer is formed from an intumescent mass based on a sodium silicate. For this purpose, a commercially available water glass solution with a water content of approx. 65% by weight is used and mixed with water glass powder with a water content of approx. 18% by weight. The gelling times of the mixture can be specifically adjusted using the amount of water glass powder. If appropriate, inorganic fillers such as metal hydroxides or metal sulfate hydrates can be added to the mixture in amounts of 0 to 50% by weight and up to 10% by weight of organic materials. The liquid mixture can be applied or sprayed directly onto the panels of the panel core material. The layer thicknesses of the coating can vary between 0.05 and 5 mm.
Die Gelierung erfolgt bei Raumtemperatur, lässt sich unter höheren Temperaturen bis 80°C aber beschleunigen. Die Platten des Kern-Materials werden so allseitig oder nur auf den später mit einer Metallplatte beklebten Breitseiten beschichtet.The gelation takes place at room temperature, but can be accelerated at higher temperatures up to 80 ° C. The plates of the core material are coated on all sides or only on the broad sides later covered with a metal plate.
Es ist auch möglich, das wärmedämmende Kernmaterial mit der Wasserglasmischung zu beschichten und vor der vollständigen Gelierung beidseitig mit den Metallplatten zu verpressen.It is also possible to coat the heat-insulating core material with the water glass mixture and to press it in on both sides with the metal plates before complete gelation.
Zusätzlich können die freiliegenden, nicht mit den Metallplatten abgedeckten Ecken und Kanten des Kernmaterials ebenfalls mit dem Beschichtungsmittel versehen oder durch Einbringen von Dämmkeilen aus Mineralwolle in die Panelen-Konstruktion zum Schutz der kritischen Stellen, wie Enden oder Falze, vor der Hitzeeinwirkung bzw. dem Flammenüberschlag geschützt werden. Das Aufschäumen der Beschichtung kann zusätzlich entstehende Öffnungen abdichten und so einen Flammenüberschlag ins Kern- Material verhindern.In addition, the exposed corners and edges of the core material that are not covered with the metal plates can also be provided with the coating agent or by inserting mineral wool insulation wedges into the panel construction Protection of critical points, such as ends or folds, should be protected from the effects of heat or flashover. The foaming of the coating can also seal openings that arise and thus prevent a flashover into the core material.
Der erfindungsgemäße Wärmedämmverbund eignet sich bevorzugt im Bauwesen, zur Fassadenverkleidung oder als sogenannte „Structural insulation panels" zur Herstellung von Lager- oder Kühlhallen.The thermal insulation composite according to the invention is preferably suitable in the building industry, for cladding facades or as so-called “structural insulation panels” for producing storage or cooling halls.

Eine Polstyrolpartikelschaumstoffplatte aus EPS (600x1000x100 mm) mit einer Schaumdichte von 18g/l wurde beidseitig mit einer 2 mm dicken Schicht einer Wasserglasmischung, bestehend aus Wasserglaslösung (Wassergehalt 65 Gew.%) vermischt mit Wasserglaspulver (Wassergehalt 18 Gew.%), beschichtet. Nach Gelierung und Aushärtung der Schicht wurde die erhaltene Platte beidseitig mit einer 50 μm Schicht eines PU-Klebers versehen und mit 1 mm dicken Stahlplatten beklebt. Zur Beurteilung der Thermostabilität und Flammbeständigkeit wurde das erhaltenen Panel nach Aushärten des Klebers horizontal befestigt und von unten über 30 Minuten lang einer Gasflamme (Flammtemperatur >500°C) ausgesetzt. Über die gesamte Testdauer von 30 Minuten schmolz nur ein geringer Teil des EPS-Schaumstoffkemmaterials und geriet nicht in Brand. Die aufschäumende Schutzschicht aus Wasserglas verhinderte weitge- hend die Schädigung des Kernmaterials und die strukturelle Integrität des Panels blieb erhalten.A polystyrene particle foam sheet made of EPS (600x1000x100 mm) with a foam density of 18 g / l was coated on both sides with a 2 mm thick layer of a water glass mixture consisting of water glass solution (water content 65% by weight) mixed with water glass powder (water content 18% by weight). After gelation and hardening of the layer, the plate obtained was provided on both sides with a 50 μm layer of PU adhesive and glued with 1 mm thick steel plates. To assess the thermal stability and flame resistance, the panel obtained was fastened horizontally after the adhesive had hardened and exposed to a gas flame (flame temperature> 500 ° C.) for 30 minutes from below. Over the entire test period of 30 minutes, only a small part of the EPS foam core material melted and did not catch fire. The foaming protective layer made of water glass largely prevented damage to the core material and the structural integrity of the panel was preserved.

Zur Beurteilung der Thermostabilität und Flammbeständigkeit wurde das erhaltenen Panel nach Aushärten des Klebers horizontal befestigt und von unten über 30 Minuten lang einer Gasflamme (Flammtemperatur >500°C) ausgesetzt. Bereits nach 5 Minuten schmolz das EPS- Schaumstoffkernmaterials und geriet in Brand und die strukturelle Integrität des Panels ging verloren. Foam density of 18 g / l was provided on both sides with a 50 μm thick layer of PU adhesive and glued with 1 mm thick steel plates. To assess the thermal stability and flame resistance, the panel obtained was fastened horizontally after the adhesive had hardened and exposed to a gas flame (flame temperature> 500 ° C.) for 30 minutes from below. After only 5 minutes the EPS foam core material melted and caught fire and the structural integrity of the panel was lost.
