Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Brandschutzdämmung, bei dem in ein offenporiges Stützgerüst aus Mineralfasern eine Kernspeichermasse, die ihr Gefüge vor Erreichen einer zulässigen Höchsttemperatur endotherm ändert, eingebettet wird.The invention relates to a method for producing fire protection insulation, in which a core storage mass, which changes its structure endothermically before reaching a permissible maximum temperature, is embedded in an open-pore support structure made of mineral fibers.

Unter Brandschutzdämmung sind Einrichtungen zu verstehen, die in Feuerschutztüren aus Stahl den Wärmedurchgang begrenzen. Solche Brandschutzdämmungen bestehen bis jetzt nur aus Einlagen aus Mineralfaserplatten. Begriff, Bezeichnung, Anforderungen und Prüfungen sind in DIN 18 089, Entwurf vom Februar 1981 festgehalten.Fire protection insulation is understood to mean devices that limit the heat transfer in steel fire doors. Until now, such fire protection insulation consisted only of inserts made of mineral fiber boards. The term, designation, requirements and tests are set out in DIN 18 089, draft from February 1981.

Ein weiteres Anwendungsgebiet für Brandschutzdämmungen sind feuersichere Schränke zur Aufbewahrung von temperatur- und feuchtigkeitsempfindlichen Gegenständen, wie Magnettonbändern, Filmen, Karteikarten od. dgl.Another area of application for fire insulation is fire-proof cabinets for storing temperature and moisture sensitive objects, such as magnetic tapes, films, index cards or the like.

Aus der US-A-3559594 ist ein feuersicherer Schrank bekannt geworden, dessen Wände aus einer äußeren dicken Betonschicht, einer innen davorgesetzten Isolierschicht aus Urethanschaum und einer innen davorgesetzten Innenwand aus Natriumazetattrihydrat bestehen. Das für die innerste Wand verwendete Natriumazetattrihydrat ist ein Stoff, der als Kernspeichermasse bezeichnet wird und bei Wärmebeaufschlagung sein Gefüge endotherm, d. h. unter Wärmeaufnahme ändert. Durch diese Gefügeänderung wird die Temperatur im Innenraum des Schrankes oder allgemein auf der von dem Brandort abgewendeten Seite einer derart ausgeschalteten Wand auf eine bestimmte Höhe zeitlich begrenzt. Allerdings ist Urethanschaum brennbar und das als Kernspeichermasse verwendete Natriumazetattrihydrat entwickelt bei Wärmeeinwirkung durch chemische Zersetzung brennbare Gase.From US-A-3559594 a fire safe cabinet has become known, the walls of which consist of an outer thick concrete layer, an inner insulating layer made of urethane foam and an inner inner wall made of sodium acetate trihydrate. The sodium acetate trihydrate used for the innermost wall is a substance called core storage mass and its structure is endothermic when exposed to heat. H. changes under heat absorption. As a result of this structural change, the temperature in the interior of the cabinet or generally on the side of a wall which has been switched off in such a way turned away from the location of the fire is limited in time to a certain height. However, urethane foam is flammable and the sodium acetate trihydrate used as the core storage mass develops flammable gases when exposed to heat through chemical decomposition.

Aus der DE-B-24 13 644 ist ein feuersicherer Schrank bekannt geworden, bei dem hinsichtlich der Sicherung des Schrankinhaltes ein besserer Wirkungsgrad dadurch erzielt ist, daß als Kernspeichermasse ein rein anorganisches, nicht brennbares Salz mit hohem Kristallwassergehalt, wie Natrium-Metasilikat-Hydrat mit 5, vorzugsweise 9 H20 Verwendung findet. Die Verwendung von Natrium-Metasilikat-Hydrat vermeidet nicht nur die Entwicklung brennbarer Gase bei Wärmebeaufschlagung, sondern erbringt wegen ihres anteilig höheren Wassergehaltes auch eine wesentlich höhere Wärmekapazität der Kernspeichermasse, als die Azetatverbindung.From DE-B-24 13 644 a fire-safe cabinet has become known, in which a better efficiency is achieved with regard to securing the cabinet contents in that a purely inorganic, non-flammable salt with high crystal water content, such as sodium metasilicate hydrate, is used as the core storage mass with 5, preferably 9 H 2 0 is used. The use of sodium metasilicate hydrate not only avoids the development of flammable gases when exposed to heat, but because of its proportionately higher water content also provides a significantly higher thermal capacity of the core storage mass than the acetate compound.

Ein anderes, gleichermaßen als Kernspeichermasse mit hoher Wärmekapazität verwendbares, rein anorganisches, nicht brennbares Salz ist beispielsweise Glaubersalz, d. h. Natriumsulfatdekahydrat.Another purely inorganic, non-flammable salt that can likewise be used as a core storage mass with a high heat capacity is, for example, Glauber's salt, i. H. Sodium sulfate decahydrate.

Dauert bei einer solchen Kernspeichermasse die Wärmebeaufschlagung an, dann schmilzt sie bei einer bestimmten Temperatur unter Wärmeaufnahme in ihrem eigenen Kristallwasser, z. B. Natrium-Metasilikat-Hydrat bei ca. 48 °C. Dabei sinkt die Schmelze nach unten ab und es entstehen in den oberen Bereichen der Brandschutzwandungen -türen oder ähnlichen Verschlußeinrichtungen, Freiräume, d. h. es entstehen dort Freiräume für den Wärmeüber- und -durchgang.With such a core storage mass, the heat exposure continues, then it melts at a certain temperature while absorbing heat in its own crystal water, e.g. B. sodium metasilicate hydrate at about 48 ° C. The melt sinks down and there are doors or similar locking devices, free spaces, d. H. there are free spaces for heat transfer and heat transfer.

Aus der DE-A-27 06 798 ist es bekannt, die Kernspeichermasse in ein offenporiges Stützgerüst einzubetten.From DE-A-27 06 798 it is known to embed the core storage mass in an open-pore support structure.

Aufgabe der Erfindung ist es, ein Verfahren zur Herstellung einer Brandschutzdämmung vorzuschlagen, durch das die Brandschutzdämmung so ausgebildet werden kann, daß die Gefahr eines Absinkens der unter fortdauernder Wärmebeaufschlagung schmelzenden Kernspeichermasse noch sicherer beseitigt werden kann, so daß die Zeit, bis zu der die Wärmedämmung voll wirksam bleibt, noch weiter erhöht ist.The object of the invention is to propose a method for producing fire protection insulation, by means of which the fire protection insulation can be designed in such a way that the risk of a sinking of the core storage mass which melts under the continuous application of heat can be eliminated even more reliably, so that the time until which the heat insulation remains fully effective, is further increased.

Diese Aufgabe wird durch die Erfindung gemäß dem kennzeichnenden Teil eines der drei möglichen Varianten gelöst, wie sie Gegenstand der Ansprüche 1 bis 3 sind.This object is achieved by the invention according to the characterizing part of one of the three possible variants, as are the subject of claims 1 to 3.

Die Zeichnung zeigt in

  • Figur 1 einen Ausschnitt aus einem feuersicheren Schrank mit einer Brandschutzdämmung nach der Erfindung ;
  • Figur 2 einen Teilschnitt durch eine mit einer Dampfsperre versehene Brandschutzdämmung zum Einbau in eine in
  • Figur 3 im Schnitt dargestellte Feuerschutztür.
The drawing shows in
  • Figure 1 shows a section of a fire-safe cabinet with fire protection insulation according to the invention;
  • Figure 2 shows a partial section through a fire barrier provided with a vapor barrier for installation in a
  • Figure 3 shown in section fire door.

In Fig. 1 bedeutet 1 den Außenmantel eines feuersicheren Schrankes mit einer Wärmedämmung nach der Erfindung, der z. B. aus Stahlblech besteht. 2, 3, 4 und 5 sind Mineralfaserplatten. 6 und 7 sind Gehäusewände, zwischen denen die Kernspeichermasse 8 vorgesehen ist, die in einem Stützgerüst 9 eingebettet ist, das beim wiedergegebenen Ausführungsbeispiel aus in Flocken zerrissener Mineralwolle besteht.In Fig. 1 1 means the outer jacket of a fire-safe cabinet with thermal insulation according to the invention, the z. B. consists of sheet steel. 2, 3, 4 and 5 are mineral fiber boards. 6 and 7 are housing walls, between which the core storage mass 8 is provided, which is embedded in a supporting structure 9 which, in the exemplary embodiment shown, consists of mineral wool torn into flakes.

In Fig. 2 ist bei 11 und 12 je eine mit Phenolharz gebundene Mineralfaserplatte von ca. 2 cm Stärke angedeutet. 13 bedeutet eine 1,5 cm starke Lage aus durch Mineralwolle gestützter Kernspeichermasse (Mischungsverhältnis 1 :4), auf die mittels einer Wasserglaskleberschicht 14 bzw. 15 jeweils eine Aluminiumfolie 16 bzw. 17 als Dampfsperre mit einer Stärke von 200 µ aufgeklebt ist. Vorzugsweise ist als Kleber eine im Handel erhältliche Brandschutzbeschichtungsmasse auf Wasserglasbasis verwendet, die bei höherer Temperatur unter Schaumbildung bläht und durch die Verdampfung bei ca. 100 °C Wärme schluckt und damit zusätzlich zur Wärmedämmung beiträgt.In Fig. 2 is indicated at 11 and 12 each with a phenolic resin bound mineral fiber plate of about 2 cm thick. 13 means a 1.5 cm thick layer of core storage mass supported by mineral wool (mixing ratio 1: 4), onto which an aluminum foil 16 or 17 is bonded as a vapor barrier with a thickness of 200 μ by means of a water glass adhesive layer 14 or 15. A commercially available fire protection coating composition based on water glass is preferably used as the adhesive, which expands at a higher temperature with the formation of foam and swallows heat through evaporation at approximately 100 ° C. and thus additionally contributes to thermal insulation.

In Fig. 3 ist ein an dem strichpunktierten Linienpaar verkürzter Längsschnitt durch eine Feuerschutztüre mit einer Brandschutzdämmung nach Fig. 2 dargestellt.FIG. 3 shows a longitudinal section, shortened by the dash-dotted lines, through a fire protection door with fire protection insulation according to FIG. 2.

Die Feuerschutztür 21 sitzt in der Türöttnung des Mauerwerks eines brandgeschützten Raumes 22 mit einem Boden 23 mit unterem Anschlag 24 und einer Decke 25 mit oberem Anschlag 26. Das Rahmenwerk der Feuerschutztür 21 ist oben bei 27 und unten bei 28 teilweise erkennbar. Ferner sind zwei Stahlblechschalen 29, 30 vorhanden. Im Inneren des durch diese Stahlblechschalen umschlossenen Raumes 31 ist eine Wärmedämmung mit dem Aufbau nach Fig. 2 vorgesehen. Dabei ist deutlich erkennbar, daß die Kernspeichermasse 13 allseitig vom Kleber 14/15 und der Aluminiumfolie 16/17 eingeschlossen ist. Bei 32 ist ein nicht Gegenstand der Erfindung bildender Türschließer schematisch und teilweise wiedergegeben.The fire protection door 21 sits in the door opening of the masonry of a fire-protected room 22 with a floor 23 with a lower stop 24 and a ceiling 25 with an upper stop 26. The framework of the fire protection door 21 is partially recognizable at 27 at the top and 28 at the bottom. There are also two sheet steel shells 29, 30. In the interior of the space 31 enclosed by these sheet steel shells, thermal insulation with the structure according to FIG. 2 is provided. It can be clearly seen that the core storage mass 13 is enclosed on all sides by the adhesive 14/15 and the aluminum foil 16/17. At 32, a door closer not forming part of the invention is shown schematically and partially.

Bei einer sogenannten feuerbeständigen Tür, die nur eine Wärmedämmung aus Mineralfasermaterial aufweist, wird für die Erreichung der geforderten Dämmwerte eine Dicke von 9 cm benötigt.In the case of a so-called fire-resistant door, which only has thermal insulation made of mineral fiber material, a thickness of 9 cm is required to achieve the required insulation values.

Verwendet man dagegen eine gemäß der Erfindung verbesserte Wärmedämmung, dann kommt man bei Erzielung gleicher Dämmwerte mit Türdicken in der Größenordnung von 5 cm aus. Es ergeben sich also in jedem Falle bei Einsatz der erfindungsgemäßen Wärmedämmung erhebliche technische und wirtschaftliche Vorteile.If, on the other hand, an improved thermal insulation is used, then the same insulation values can be achieved with door thicknesses of the order of 5 cm. In any case, there are considerable technical and economic advantages when using the thermal insulation according to the invention.
