Abstract

The invention relates to a substance combination which, in a wall/ceiling opening, seals off the cables/pipes which pass through with respect to the opening such that, in the event of fire, the fire is prevented from passing through the opening from one area to another. The essential component of the substance combination is a cellulose fibre mixture which is discharged as a light waste fraction from the cleaning plants of the paper recycling industry. By addition of and intimate mixing with magnesium oxide and magnesium sulphate, the resulting mixture gives, after hardening, a fire-resistant, dimensionally stable, extremely lightweight, water-resistant and gas-impermeable product which can easily be penetrated for the subsequent laying of cables (pipes) and can be sealed again using the same composition. This composition is easy to process and presents no health hazard.

Description

Die Erfindung betrifft eine feuerfeste Dicht-Stopfmasse, die durch ihre Zusammen­ setzung und nach der Aushärtung ein feuerfestes, wärmeisolierendes und elektrisch nichtleitendes Verhalten zeigt, welches sie zur Abschottung, Abdichtung von Kabel- oder Rohrdurchführungen in Wänden- oder Deckenöffnungen und Bauteilen, wie Hohl-Zwischenräume und Fugen einsetzen läßt. Ferner bezieht sich die Erfindung auf den Einsatz als Plattenmaterial zur feuerfesten Wärmeisolierung.The invention relates to a refractory sealing stuffing compound, by their together setting and after curing a fireproof, heat-insulating and electrical non-conductive behavior shows what they are used for sealing, sealing of cable or pipe penetrations in wall or ceiling openings and components, such as Can use hollow spaces and joints. The invention further relates on the use as sheet material for fire-proof heat insulation.

Es ist bekannt, daß zum vorbeugenden Brandschutz für Kabel- oder Rohrdurch­ führungen durch Wand- oder Deckenöffnungen Brandschutzmaterialien eingesetzt werden, deren Zusammensetzung meistens aus einem Flammschutzmittel, Füll­ mittel, Bindemittel und thermisch expandierenden, intumeszierenden Substanzen bestehen. Beschrieben werden solche Kombinationen in der AT-PS 3 60 130, EP-A-51 106, DE-AS 11 76 546, DE-AS 11 69 832, DE-OS 24 50 286 und AT-PS 3 54 582. Außerdem hält die Firma BAYER unter der Bezeichnung FOMOX P® und FOMOX XSD® und die Firma REINHOLD CHEMIE das Produkt BECKONIT® als Flammschutzmittel bereit, denen allen gemeinsam ist, unter thermischer Einwirkung ihr ursprüngliches Volumen um ein vielfaches zu vergrößern, dadurch Hohlräume, Lücken und Spalten ausfüllt, damit eine Abdichtung gegen Flammen und Rauchgase zu unmittelbar daneben liegende Räume gewähr­ leistet ist.It is known that for preventive fire protection for cable or pipe through guides through wall or ceiling openings fire protection materials used be, the composition of which mostly consists of a flame retardant, filling agents, binders and thermally expanding, intumescent substances consist. Such combinations are described in AT-PS 3 60 130, EP-A-51 106, DE-AS 11 76 546, DE-AS 11 69 832, DE-OS 24 50 286 and AT-PS 3 54 582. The company BAYER also holds under the name FOMOX P® and FOMOX XSD® and the company REINHOLD CHEMIE das BECKONIT® product ready as a flame retardant that is common to all their original volume increases many times under the influence of heat enlarge, thereby filling voids, gaps and gaps, so that a seal against fire and flue gases to rooms directly adjacent is accomplished.

Als Nachteil dieser Brandschutzmaterialien wird in der Europäischen Patentan­ meldung, Veröffentlichungsnummer 01 53 564 S. 3, vorgetragen, daß aufgrund des relativ geringen oder praktisch fehlenden Blähdrucks, die Bildung einer fest ab­ dichtenden Sperrschicht nur sehr schwer und mit großen Materialverbrauch möglich ist.The disadvantage of these fire protection materials is in the European patent report, publication number 01 53 564 p. 3, submitted that due to the relatively low or practically absent inflation pressure, the formation of a firm sealing barrier layer is very difficult and uses large amounts of material is possible.

Im Gegensatz dazu ist es Aufgabe der vorliegenden Erfindung, eine feuerfeste Abdichtung, Abschottung für Wand- oder Deckenöffnungen mit hoher Wärmeisolierung durch die Substanzkombination und Verarbeitungstechnik herbei­ zuführen. Die Substanzkombination ist toxisch unbedenklich und spaltet selbst bei Temperaturen von 1000°C keine toxischen Gase ab. In contrast, it is an object of the present invention to Fireproof sealing, partitioning for wall or ceiling openings with high Thermal insulation through the combination of substances and processing technology respectively. The combination of substances is toxic harmless and cleaves itself Temperatures of 1000 ° C no toxic gases.  

Die Zusammensetzung besteht aus dem Abfallprodukt, welches in einer Clean­ anlage der Papierindustrie zur Herstellung von Karton oder Papiere aus Recycling­ material anfällt und einer Mischung von Magnesiumoxid und Magnesiumsulfat. Die in der Cleananlage der Papierindustrie durch künstliche Schwerkraft abge­ trennten Bestandteile aus dem Recyclingmaterial fallen in einer schweren und leichten Fraktion an. Die Leichtere mit einem hohen Anteil an faseriger Zellulose wird vorher bis zu 70% entwässert und vor dem Einsatz als Dicht-Stopfmasse mit einem Anteil vonThe composition consists of the waste product, which is in a clean Plant of the paper industry for the production of cardboard or paper from recycling material and a mixture of magnesium oxide and magnesium sulfate. In the clean plant of the paper industry by artificial gravity separated components from the recycling material fall into a heavy and light fraction. The lighter with a high proportion of fibrous cellulose is dewatered up to 70% beforehand and also used as a sealing stuffing a share of

Die Abschottung, Abdichtung einer Wand- oder Deckenöffnung kann durch eingießen (betonieren), oder einmauern einer nach Vorschrift dimensionierten Platte aus der oben beschriebenen Materialkombination hergestellt werden Fig. 1-4. Die benötigenden Öffnungen für die Kabel- oder Rohrdurchführungen sind aus­ zubohren, die Kabel oder Rohre einzuziehen und ein verbliebener Ringspalt mit frisch angesetzter Dicht-Stopfmasse abzudichten. Nach diesem Verfahren erfolgt auch eine Nachbelegung mit neuen Kabeln oder Rohren.The partitioning, sealing of a wall or ceiling opening can be made by pouring (concreting) or walling in a plate dimensioned according to the regulations from the material combination described above, Fig. 1-4. The required openings for the cable or pipe penetrations must be drilled out, the cables or pipes drawn in and a remaining annular gap sealed with freshly added sealing stuffing compound. This procedure is also followed by new cables or pipes.

Eine weitere Möglichkeit der Abdichtung, Abschottung besteht durch schichtweises eintragen der Dicht-Stopfmasse mit anschließender Kabellage, Rohren und so fort, wie es in Fig. 5-10 gezeigt ist. In einer mit Kabeln, Rohren durchzogenen Wandöffnung werden alle Kabel angehoben und eine erste Schicht, ca. 10 cm stark, mit der Dicht-Stopfmasse gebildet. In diese erste Schicht wird die erste Lage Kabel hineingedrückt und die nächste Schicht Dicht-Stopf­ masse aufgetragen, die nächste Lage Kabel hineingedrückt und so fort, bis alle Kabel eingebettet sind. Eine verbliebene Restöffnung kann mit Platten­ material, Ziegel bestehend aus der Dicht-Stopfmasse, verschlossen werden.Another possibility of sealing, partitioning is by layer-by-layer entry of the sealing stuffing with subsequent cable layer, pipes and so on, as shown in Fig. 5-10. In a wall opening with cables, pipes, all cables are raised and a first layer, approx. 10 cm thick, is formed with the sealing stuffing compound. The first layer of cable is pressed into this first layer and the next layer of sealing compound is applied, the next layer of cable is pressed in and so on until all cables are embedded. A remaining opening can be closed with plate material, brick consisting of the sealing stuffing.
