Abstract

Silicated expanded asbestos forming high-temperature insulation material is resistant to temperatures from 1800 to 2000 deg. C, has a material density of 0.23 to 0.6 g/cm<3>, compressive strength of 7 to 7000 N/cm<2>, and is resistant to acids and alkalis. The material is manufactured by a process in which short-fibre asbestos is homogenised with additives, water and water glass and is fired in a tunnel furnace with open flame at 1500 to 2000 deg. C before being chopped.

Description

Die Erfindung betrifft einen hochtemperaturbeständigen Isolierstoff mit vielseitigen Einsatzmöglichkeiten sowie ein Verfahren zu seiner Herstellung.The invention relates to a high temperature resistant Insulating material with versatile uses as well as a Process for its manufacture.

Es gibt eine Vielzahl temperaturbeständiger Isolierstoffe. Vermiculit besitzt zwar sehr gute Dämmeigenschaften, jedoch wird durch die sehr schlechten mechanischen Eigenschaften die Gebrauchsdauer erheblich eingeschränkt.There are a variety of temperature-resistant insulating materials. Vermiculite has very good insulation properties, however is due to the very poor mechanical properties Service life considerably limited.

Glaswolle besitzt ebenfalls gute Isoliereigenschaften. Die Temperaturbeständigkeit ist auf 500 bis 600°C beschränkt.Glass wool also has good insulating properties. The Temperature resistance is limited to 500 to 600 ° C.

Hochofenschlackenwolle besitzt zwar eine gute Temperatur­ beständigkeit, jedoch ist die größere Dichte und schlechtere Dämmeigenschaft von erheblichem Nachteil.Blast furnace slag wool has a good temperature resistance, however, the greater density and worse Insulation property of considerable disadvantage.

Schamottematerialien besitzen brauchbare Dämmeigenschaften, die mechanische Festigkeit ist jedoch völlig unzureichend.Firebrick materials have useful insulation properties, however, the mechanical strength is completely inadequate.

Aufgabe der Erfindung ist es, einen hochtemperaturbeständigen Isolierstoff mit weiteren vorteilhaften mechanischen Eigen­ schaften vorzuschlagen.The object of the invention is a high temperature resistant Insulating material with further advantageous mechanical properties propose.

Erfindungsgemäß wird der hochtemperaturbeständige Isolier­ stoff auf der Basis eines silikatisierten Blähasbestes durch die Merkmale des Kennzeichenteiles des Hauptanspruches charakterisiert.According to the high temperature resistant insulation fabric based on a silicatized expanded asbestos the characteristics of the characterizing part of the main claim characterized.

Die Verfahrensmerkmale der Ansprüche beschreiben die vorteil­ hafte Herstellung des Blähasbestes. The process features of the claims describe the advantage adhesive production of expanded asbestos.  

Nachfolgend soll die Erfindung an einem Beispiel näher erläutert werden.The invention will be explained in more detail below using an example are explained.

Zunächst erfolgt in einem Zwangsmischer die Herstellung einer homogenen Masse aus Kurzfaserasbest, leichten Zuschlagsstof­ fen, Wasser und Wasserglas (K-Na-Silikat). Danach erfolgt eine Formgebung durch Extrusionspressen oder durch Eintragen in Flach- oder Blockformen. Diese vorgeformten Halbfabrikate werden nunmehr einige Zeit, beispielsweise 2 Tage, an der Luft gelagert, um durch einen Silikatisierungsvorgang eine Oberflächenverkrustung zu erreichen. In einem kleinen Tunnelofen mit offener Flamme erfolgt bei 1500 bis 2000°C innerhalb eines Zeitraumes von 10 bis 15 min ein Erzeugnisbrand, wodurch eine Aufblähung erfolgt.First, a is made in a compulsory mixer homogeneous mass of short fiber asbestos, light aggregate fen, water and water glass (K-Na silicate). After that is done shaping by extrusion presses or by insertion in flat or block shapes. These preformed semi-finished products are now in the air for some time, for example 2 days stored to a through a silicatization process To achieve surface incrustation. In a little one Tunnel furnace with an open flame takes place at 1500 to 2000 ° C within a period of 10 to 15 minutes Product fire, causing bloating.

Vorzugsweise sollte die Durchlaufgeschwindigkeit im Tunnelofen 0,1 bis 0,2 m/min betragen.The throughput speed in the tunnel kiln should preferably be used 0.1 to 0.2 m / min.

Der erzeugte Blähasbest wird anschließend zerkleinert.The expanded asbestos is then crushed.
