Abstract
Description
Die Erfindung betrifft ein flächiges Brandschmutzmaterial auf Basis von wasserhaltigem, faserverstärktem Natriumsilikat, welches mit einer Schutzschicht versehen ist.The invention relates to a flat fire dirt material Basis of water-containing, fiber-reinforced sodium silicate, which is provided with a protective layer.
Brandschutzmaterialien aus wasserhaltigen Alkalimetallsilikaten sind seit langem bekannt und werden bereits vielfältig für den vorbeugenden Brandschutz eingesetzt. Sie bewirken bei hohen Temperaturen, wie sie z. B. im Brandfall auftreten, durch Schaum bildung, Volumenvergrößerung und Ausbildung eines Blähdrucks eine hervorragende Isolierung gegen Feuer und Rauch, und führen so eine Abdichtung von Öffnungen und Durchgängen in Baukörpern her bei. Derartige Materialien sowie Verfahren zu ihrer Herstellung sind z. B. in der DE-B 11 69 832 beschrieben. In der genannten Druckschrift wird empfohlen, die Brandschutzplatten gegen das Verdunsten des Wassers durch Kunststoffschichten, z. B. Poly ethylenüberzüge zu schützen. Diese sind jedoch für Kohlendioxid durchlässig, welches durch chemische Reaktion die Wirksamkeit des wasserhaltigen Natriumsilikats mindert. Nach DE-A 16 21 799 sollen deshalb festhaftende (Überzüge aus Epoxidharz/Härter-Ge mischen auf die Brandschutzplatten aufgebracht werden.Fire protection materials made from water-containing alkali metal silicates have been known for a long time and are already diverse for the preventive fire protection. They work at high Temperatures such as B. occur in the event of fire, by foam education, volume increase and development of a swelling pressure excellent insulation against fire and smoke, and so lead sealing openings and passages in buildings at. Such materials and processes for their manufacture are z. B. described in DE-B 11 69 832. In the above Documentation is recommended to protect the fire protection panels against the Evaporation of the water through plastic layers, e.g. B. Poly to protect ethylene coatings. However, these are for carbon dioxide permeable, which by chemical reaction the effectiveness of hydrated sodium silicate. According to DE-A 16 21 799 should therefore adhere firmly (coatings made of epoxy resin / hardener Ge mix can be applied to the fire protection panels.
Handelsübliche Brandschutzplatten, z. B. PALUSOL der BASF AG, sind maximal 4 mm dick. Probleme ergeben sich daher, wenn konstruktiv bedingt breitere Bauteilfugen oder Fugen mit variierender Spalt breite abgedichtet werden sollen, beispielsweise Fugen an brand geschützten Bodentreppen.Commercial fire protection panels, e.g. B. PALUSOL from BASF AG maximum 4 mm thick. Problems arise when constructive requires wider component joints or joints with a varying gap wide should be sealed, for example joints on fire protected floor stairs.
Diese Probleme werden gelöst, wenn man mindestens eine Schicht A aus wasserhaltigem, faserverstärktem Natriumsilikat kombiniert mit mindestens einer Schicht B aus einem flexiblen offenzelligen Schaumstoff.These problems are solved if at least one layer A combined from water-containing, fiber-reinforced sodium silicate with at least one layer B of a flexible open cell Foam.
Die Schicht A liegt im allgemeinen in Form von Platten vor, die z. B. 210 cm lang, 110 cm breit und 1 bis 5 mm dick sein können. Diese können auch bereits zu 2 bis 10 cm breiten Streifen ge schnitten sein.Layer A is generally in the form of plates that e.g. B. 210 cm long, 110 cm wide and 1 to 5 mm thick. These can also be ge to 2 to 10 cm wide strips be cut.
Das Brandschutzmaterial besteht aus wasserhaltigem Natriumsilikat mit einem Wassergehalt von 20 bis 50, vorzugsweise von 25 bis 40 Gew.-%, dem zur Verstärkung Glasfasern in Mengen von 2 bis 20 Gew.-% zugefügt sind. Weitere Einzelheiten über Aufbau und Herstellung des Brandschutzmaterials sind in den genannten Druck schriften beschrieben. Das Brandschutzmaterial ist üblicherweise mit einem Epoxidharz-Überzug umhüllt und mit einer Schutzschicht, z. B. mit einer Aluminiumfolie oder mit einer Folie aus Polyester, Polyethylen, Polyvinylchlorid oder Papier kaschiert.The fire protection material consists of water-containing sodium silicate with a water content of 20 to 50, preferably 25 to 40 wt .-%, for reinforcing glass fibers in amounts of 2 to 20 wt .-% are added. More details on construction and Manufacture of fire protection material are in the mentioned pressure writings described. The fire protection material is common covered with an epoxy resin coating and with a protective layer, e.g. B. with an aluminum foil or with a polyester film, Laminated with polyethylene, polyvinyl chloride or paper.
Schicht B besteht aus einem flexiblen, offenzelligen Schaumstoff. Geeignet sind Schaumstoffe aus Kondensationsharzen auf Basis von Melamin-, Harnstoff- und Phenol-Formaldehyd. Besonders bevorzugt sind elastische Schaumstoffe auf Basis von Melaminharzen, wie sie z. B. in EP-B 71 672 beschrieben sind. Ein geeigneter Schaumstoff ist z. B. BASOTECT der BASF AG. Diese Schaumstoffe haben im allge meinen ein spezifisches Gewicht von 5 bis 100 g/l, insbesondere von 8 bis 20 g/l und eine Dicke von 5 bis 50 mm, vorzugsweise von 10 bis 30 mm.Layer B consists of a flexible, open-cell foam. Foams made from condensation resins based on Melamine, urea and phenol formaldehyde. Particularly preferred are elastic foams based on melamine resins, like them e.g. B. are described in EP-B 71 672. A suitable foam is z. B. BASOTECT from BASF AG. These foams generally have mean a specific weight of 5 to 100 g / l, in particular from 8 to 20 g / l and a thickness of 5 to 50 mm, preferably from 10 to 30 mm.
Sie erreichen im Brandtest nach DIN 4102 im allgemeinen die Brandschutzklasse B 1.In the fire test according to DIN 4102 you generally achieve the Fire protection class B 1.
Zusätzlich zu dem Flexibilisierungseffekt bringt der Schaumstoff auch noch seine guten Eigenschaften bezüglich Wärmedämmung und Schallschutz ein; bei Brandbeginn verhindert er (Dauereinsatz temperaturen bis 150°C) den Durchgang von toxischen Rauchgasen, im weiteren Brandverlauf verschließt der ab ca. 100°C sich bildende Silikatschaum sicher die Fuge gegen Rauch.In addition to the flexibility effect, the foam brings also its good properties in terms of thermal insulation and Soundproofing on; at the start of the fire, it prevents (continuous use temperatures up to 150 ° C) the passage of toxic smoke gases, in The further course of the fire is blocked by the one that forms at approx. 100 ° C Silicate foam secures the joint against smoke.
Eine bevorzugt Schichtfolge ist ABA, in manchen Fällen genügt auch ein Zweierverbund AB; bei sehr breiten Spalten kann auch ein Verbund BAB, ABAB oder ABABA günstig sein. Die Schichten A und B können mit einem doppelseitigen Klebeband oder mit üblichen Klebern, z. B. auf Basis von Acrylaten, Kautschuk oder Phenol harzen miteinander verbunden werden.A preferred layer sequence is ABA, in some cases sufficient also a two-way network AB; for very wide gaps, a Verbund BAB, ABAB or ABABA can be cheap. Layers A and B can with a double-sided tape or with usual Glue, e.g. B. based on acrylates, rubber or phenol resins are bonded together.
