PCT No. PCT/AT92/00137 Sec. 371 Date Sep. 23, 1993 Sec. 102(e) Date Sep. 23, 1993 PCT Filed Nov. 4, 1992 PCT Pub. No. WO93/16250 PCT Pub.

Description

Die Erfindung betrifft ein Verfahren zum monolithischen Aufbringen einer Dämm- und/oder Brandschutzmasse auf eine Fläche mittels einer Spritzpistole, in der knapp vor dem düsenförmigen Austritt gasförmiges Druckmittel und Bindemittel oder Kleber eingebracht werden und eine Vorrichtung zur Durchführung des Verfahrens mit einer Spritzpistole, in die ein Schlauch für die Zufuhr von gasförmigem Druckmittel, eine Zuleitung für Bindemittel oder Kleber sowie ein Schlauch für die Zufuhr eines Dämm- und/oder Brandschutzstoffes einmünden.The invention relates to a method for the monolithic application of an insulation and / or fire protection compound to a surface by means of a spray gun, in which gaseous pressure medium and binder or adhesive are introduced just before the nozzle-shaped outlet, and a device for carrying out the method with a spray gun into which a hose for the supply of gaseous pressure medium, a feed line for binder or adhesive and a hose for the supply of an insulation and / or fire protection material open.

Seit einiger Zeit ist bekannt, daß Asbest gesundheitsschädlich ist und daher im Bauwesen, vor allem für geschlossene Innenräume vermieden werden soll. Andererseits sind Asbest enthaltende Baustoffe brandbeständig, was den vielschichtigen Einsatz in Form von festen Bauelementen sowie in Form flüssiger Grundstoffe (Materialien), die gegossen oder gespritzt wurden, verständlich macht. Zusätzlich ist Asbest ein schlechter Wärmeleiter, wodurch eine gewisse Wärmedämmung gegeben war.It has been known for some time that asbestos is harmful to health and should therefore be avoided in construction, especially for closed interiors. On the other hand, asbestos-containing building materials are fire-resistant, which makes the multilayered use in the form of solid components and in the form of liquid raw materials (materials) that have been cast or sprayed understandable. In addition, asbestos is a poor conductor of heat, which gave it a certain amount of thermal insulation.

Infolge der Erkenntnis der Gesundheitsschädlichkeit von Asbest wurden Ersatzstoffe gesucht, die vor allem ähnlich gute Brandbeständigkeit zeigen. Solche Stoffe mit ähnlich guten Brandschutzeigenschaften sind z.B. Vermiculite und Perlite, die zusätzlich hautfreundlich sind und bei ihrer Handhabung keinen besonderen Schutz erfordern und darüber hinaus auch gute Schall- und Wärmedämmung bieten. Für Dämmungen wird z.B. auch Steinwolle und dgl. eingesetzt, die bei der Verarbeitung auch nur geringe Schutzmaßnahmen erfordert.As a result of the knowledge that asbestos was harmful to health, substitutes were sought which above all showed similarly good fire resistance. Such substances with similarly good fire protection properties are e.g. Vermiculite and perlite, which are also skin-friendly and require no special protection when handling them, and also offer good sound and heat insulation. For insulation, e.g. rock wool and the like are also used, which also requires only minor protective measures during processing.

Trotz intensiven Versuchens ist es bisher nicht gelungen eine Dämm - und/oder Brandschutzmasse mit den vorgenannten Materialien herzustellen, die monolithisch auf eine glatte Oberfläche ohne Haftgrund und ohne mechanische Befestigungsmittel, z.B. als Spritzverputz, aufgebracht werden kann.Despite intensive testing, it has so far not been possible to produce an insulation and / or fire protection compound with the abovementioned materials which is monolithic on a smooth surface without a primer and without mechanical fasteners, e.g. as spray plaster, can be applied.

Es sind Verfahren und Vorrichtungen, z.B. aus der US-PS 3 740 260, bekannt, bei denen einer Spritzpistole getrennt flüssiges Beschichtungsmaterial, fasriger Dämmstoff und Druckluft zugeführt werden, um diese Komponenten knapp vor dem Auftragen zu vermischen. Bei dem zuvor genannten Dämm- und/oder Brandschutzstoffen findet auf diese Weise, vor allem wegen dem geringen spezifischen Gewicht, jedoch keine zufriedenstellende Durchmischung statt.Methods and devices are known, for example from US Pat. No. 3,740,260, in which a spray gun separately liquid coating material, fibrous insulation and compressed air are supplied to mix these components just before application. In the case of the above-mentioned insulation and / or fire protection materials, however, there is no satisfactory mixing, primarily because of the low specific weight.

Aufgabe der Erfindung ist es, ein Verfahren zu finden und eine Vorrichtung zu schaffen, um eine Dämm- und/oder Brandschutzmasse monolithisch auf eine Fläche aufbringen zu können, wobei eine vollständige Durchmischung gesichert ist.The object of the invention is to find a method and to create a device in order to be able to apply an insulation and / or fire protection compound monolithically to a surface, complete mixing being ensured.

Diese Aufgabe wird dadurch gelöst, daß bei einem Verfahren der eingangs genannten Art in einem Förderkanal durch ein Fördergebläse ein bewegtes Luftvolumen erzeugt wird, in das ein Dämm- und/oder Brandschutzstoff und Härter eingebracht werden, die mit dem Luftvolumen in die mit dem Förderkanal verbundene Spritzpistole gelangen. Die so erzeugte Dämm- und/oder Brandschutzmasse läßt sich monolithisch und dauerhaft auf eine Fläche aufbringen, und behält die den Dämm- und/oder Brandschutz stoffen spezifischen Eigenschaften.This object is achieved in that a moving air volume is generated in a conveyor channel by a conveyor fan in a method of the type mentioned, in which an insulating and / or fire protection material and hardener are introduced, which are connected with the air volume in the with the conveyor channel Spray gun. The insulation and / or fire protection compound produced in this way can be monolithically and permanently applied to a surface and retains the properties specific to the insulation and / or fire protection.

Insbesondere wird zuerst der Damm- und/oder Brandschutzstoff und danach getrennt vorzugsweise pulverförmiger Härter in das Luftvolumen eingebracht.In particular, the dam and / or fire protection substance and then preferably powdered hardener is introduced separately into the air volume.

Besonders geeignet ist das erfindungsgmäße Verfahren für Dämm- und/oder Brandschutzstoffe, die ein geringeres spezifisches Gewicht haben als das Bindemittel, da der relativ leichte Dämm- und/oder Brandschutzstoff ohne Probleme in dem Luftvolumen transportiert werden kann und später das relativ schwere Bindemittel oder der relativ schweren Kleber zugesetzt wird.The method according to the invention is particularly suitable for insulation and / or fire protection materials which have a lower specific weight than the binder, since the relatively light insulation and / or fire protection material can be transported without problems in the air volume and later the relatively heavy binder or relatively heavy glue is added.

Geeignete Dämm- und/oder Brandschutzstoffe sind Vermiculite, Perlite oder Steinwolle und dgl..Suitable insulation and / or fire protection materials are vermiculite, perlite or rock wool and the like.

Als Bindemittel kann ein Kleber, insbesondere ein Brandchutzkleber verwendet werden.An adhesive, in particular a fire protection adhesive, can be used as the binder.

Am Beginn des Verfahrens wird das Einschalten des Fördergebläses, der Beginn der Zufuhr von Dämm- und/oder Brandschutzstoff, von Härter und von Bindemittel oder Kleber vorzugsweise durch eine Steuereinheit gemäß des jeweiligen spezifischen Gewichts und des jeweiligen Förderweges verzögert. Die Verzögerung der Zufuhr der einzelnen Komponenten, gleicht die aufgrund der unterschiedlichen spezifischen Gewichte unterschiedlichen Beschleunigungszeiten und die unterschiedlichen Entfernungen der Zufuhrstellen zur Ausgangsdüse der Spritzpistole aus. Alle Komponenten haben nach ihrer Beschleunigungsphase die gleiche Geschwindigkeit, nämlich die des Luftvolumens, wodurch ein gleichmäßiger Transport der Komponenten erreicht wird.At the beginning of the process, the switching on of the conveying fan, the beginning of the supply of insulation and / or fire protection material, of hardener and of binder or adhesive is preferably delayed by a control unit in accordance with the respective specific weight and the respective conveying path. The delay in the delivery of the individual components compensates for the different acceleration times due to the different specific weights and the different distances of the delivery points to the outlet nozzle of the spray gun. After their acceleration phase, all components have the same speed, namely that of the air volume, which ensures uniform transport of the components.

Die erfindungsgemäße Vorrichtung ist dadurch gekennzeichnet, daß in einer Vorrichtung der eingangs genannten Art ein Fördergebläse mit seiner Ansaugseite an ein Ende eines Förderkanals angeschlossen ist, in den mindestens eine Abgabevorrichtung für den Dämm- und/oder Brandschutzstoff und für Härter einmündet und daß das Fördergebläse an seiner Abgabeseite einen Anschluß für den Schlauch zur Zufuhr des mit dem Härter vermischten Dämm- und/oder Brandschutzstoffes zur Spritzpistole aufweist. Der Dämm- und/oder Brandschutzstoff und der Härter werden dabei nicht durch den Förderkanal geblasen, was bei manchen leichten Stoffen aufgrund ihrer spezifischen Gewichte unmöglich bzw. schwierig wäre, sondern sie werden mit dem bewegten Luftvolumen angesaugt.The device according to the invention is characterized in that, in a device of the type mentioned at the outset, a conveying fan is connected with its suction side to one end of a conveying channel into which at least one dispensing device for the insulation and / or fire protection material and for hardener opens and that the conveying fan is on its discharge side has a connection for the hose for supplying the insulation and / or fire protection material mixed with the hardener to the spray gun. The insulation and / or fire protection material and the hardener are not blown through the delivery channel, which would be impossible or difficult for some light materials due to their specific weights, but are sucked in with the moving air volume.

Der Förderkanal weist an seinem anderen Ende vorzugsweise eine Regelklappe auf, mit der die Luftmenge im Förderkanal gesteuert werden kann.At its other end, the conveying duct preferably has a control flap with which the amount of air in the conveying duct can be controlled.

In den Förderkanal münden vorzugsweise je eine Abgabevorrichtung für den Dämm- und/oder Brandschutzstoff und den Härter. Durch die getrennte Zugabe kann jederzeit das Mischungsverhältnis geändert werden. Die dosierte Abgabe kann z.B. bei der Abgabevorrichtung für den Härter durch eine motorgetriebene Schnecke und bei der Abgabevorrichtung für den Dämm- und/oder Brandschutzstoff über ein Druckluftventil erfolgen.A delivery device for the insulation and / or fire protection material and the hardener preferably open into the delivery channel. The mixing ratio can be changed at any time by the separate addition. The metered delivery can take place, for example, in the delivery device for the hardener by means of a motor-driven screw and in the delivery device for the insulation and / or fire protection material via a compressed air valve.

Zur Steuerung dieser Abgabevorrichtungen für den Dämm- und/oder Brandschutzstoff und den Härter und der Abgabevorrichtung für das Bindemittel oder den Kleber, sowie der Zufuhr von Druckmittel und des Fördergebläses ist eine elektronische steuervorrichtung vorgesehen. Damit ist bei vorgewählter Fördermenge und vorgewähltem Mischungsverhältnis eine einfache Bedienung der Vorrichtung bei gleichbleibendem Arbeitsergebnis gegeben.An electronic control device is provided to control these dispensing devices for the insulation and / or fire protection material and the hardener and the dispensing device for the binder or the adhesive, as well as the supply of pressure medium and the conveying fan. With a preselected delivery rate and preselected mixing ratio, the device is easy to operate with the same work result.

Weitere Details des Verfahrens und der Vorrichtung ergeben sich aus der nun folgenden Beschreibung einer Ausführungsvariante der erfin-dungsgemäßen Vorrichtung. Dabei stellt Fig.1 die Vorrichtung in einer Seitenansicht und Fig.2 die Spritzpistole dar.Further details of the method and the device result from the following description of an embodiment variant of the device according to the invention. 1 shows the device in a side view and FIG. 2 shows the spray gun.

Wie man in Fig.1 sieht ist ein Fördergebläse 2 mit einem Ende eines Förderkanals 1 einerseits und einem Anschluß 12 andererseits verbunden. Der Förderkanal 1 weist an seinem anderen Ende eine Regelklappe 16 auf. Zwischen der Regelklappe 16 und dem Fördergebläse 2 münden jeweils eine Abgabevorrichtung 10, 11 für einen Dämm-und/oder Brandschutzstoff 3 und Härter 4. Die Abgabe des Dämm- und/oder Brandschutzstoffes 3 wird durch ein Druckluftventil 17 und die Abgabe des Härters 4 durch eine mittels Motor 18 getriebene Schnecke geregelt. Vom Anschluß 12 führt ein Schlauch 13 zu der in Fig.2 dargestellten Spritzpistole 5, in welche über einen Schlauch 14 Druckluft 7 von einer Druckluftabgabevorrichtung 15 einerseits und über eine Leitung 20 und ein Ventil 19 Bindemittel oder Kleber 8 andereseits eingebracht werden.As can be seen in FIG. 1, a conveying fan 2 is connected to one end of a conveying channel 1 on the one hand and to a connection 12 on the other hand. The conveying channel 1 has a control flap 16 at its other end. A dispensing device 10, 11 for an insulation and / or fire protection substance 3 and hardener 4 each open between the control flap 16 and the conveying fan 2. The discharge of the insulation and / or fire protection substance 3 is achieved by a compressed air valve 17 and the discharge of the hardener 4 regulates a worm driven by motor 18. From the connection 12, a hose 13 leads to the spray gun 5 shown in FIG. 2, into which compressed air 7 from a compressed air delivery device 15 on the one hand and via a line 20 and a valve 19 binder or adhesive 8 on the other hand are introduced via a hose 14.

Bei Arbeitsbeginn bewirkt ein Einschalten der Vorrichtung über die Steuereinheit 9 das Starten des Fördergebläses 2. Sobald ein bewegtes Luftvolumen aufgebaut ist, wird von der Steuereinrichtung 9 die Abgabevorrichtung 10 aktiviert und eine konstantbleibende Menge an Dämm- und/oder Brandschutzstoff 3 in das Luftvolumen eingebracht, dann wird mit etwas Zeitverzögerung die Abgabevorrichtung 11 aktiviert und eine konstantbleibende Menge Härter 4 ebenfalls in das Gemisch aus Luft und Dämm- und/oder Brandschutzstoff eingebracht. Das Fördergebläse 2 saugt das Luftvolumen mit dem Dämm- und/oder Brandschutzstoff 3 und dem Härter 4 an und transportiert es zur Spritzpistole 5. Dort wird wiederum etwas später Bindemittel oder Kleber 8 beigemengt. Aufgrund der verschiedenen spezifischen Gewichte von Damm- und/oder Brandschutzstoff 3, Härter 4 und Bindemittel oder Kleber 8 haben diese einzelnen Komponenten verschiedene Beschleunigungszeiten in dem Luftvolumen, diese werden durch die elektronische Steuerung ausgeglichen. Die zeitlichen Verzögerungen beim Einschalten der jeweiligen Abgabevorrichtungen bei Arbeitsbeginn, bewirken, daß das aus dem düsenförmigen Austritt 6 mit dem gasförmigen Druckmittel ausgespritzte Gemisch von Beginn an das vorgewählte Mischungsverhältnis aufweist, d.h. von Beginn an verarbeitungsfähig ist. Beim Abschalten der Vorrichtung steuert die Steuereinrichtung 9 die Abschaltung der einzelnen Abgabevorrichtungen und des Fördergebläses in umgekehrter Reihenfolge, sodaß auch am Arbeitsende keine unbrauchbaren Verlustmengen entstehen.At the start of work, switching on the device via the control unit 9 causes the delivery blower 2 to start. As soon as a moving air volume has built up, the control device 9 activates the delivery device 10 and introduces a constant amount of insulation and / or fire protection material 3 into the air volume. then the dispensing device 11 is activated with a slight time delay and a constant amount of hardener 4 is also introduced into the mixture of air and insulation and / or fire protection material. The conveyor blower 2 sucks the air volume with the insulation and / or fire protection material 3 and the hardener 4 and transports it to the spray gun 5. There, a little later, binder or adhesive 8 is added. Due to the different specific weights of dam and / or fire protection material 3, hardener 4 and binder or adhesive 8, these individual components have different acceleration times in the air volume, these are compensated for by the electronic control. The time delays when the respective dispensing devices are switched on at the start of work have the effect that the mixture sprayed with the gaseous pressure medium from the nozzle-shaped outlet 6 has the preselected mixing ratio from the start, ie it can be processed from the start. When the device is switched off, the control device 9 controls the switching off of the individual dispensing devices and of the conveying fan in the reverse order, so that there are no useless loss quantities even at the end of the work.

Z.B. wurde bei entsprechenden Versuchen für die Herstellung der Prüfflächen für die Prüfprogramme lt. Ö-Norm B 3800 und Ö-Norm S 5104 Vermiculite mit einer Korngröße von 3 bis 6 mm, pulverförmoger Härter und der lösungsmittelfreie Burian-Stahl-Brandschutzkleber der Firma Burian Ges.m.b.H. & Co.KG verwendet.E.g. was used in corresponding tests for the production of the test surfaces for the test programs according to Ö-Norm B 3800 and Ö-Norm S 5104 Vermiculite with a grain size of 3 to 6 mm, powdered hardener and the solvent-free Burian steel fire protection adhesive from Burian Ges. mbH & Co.KG used.

Die Versuche zeigten, daß die aus den obengenannten Materialien nach dem erfindungsgemäßen Verfahren hergestellte Dämm- und Brandschutzmasse brandbeständig entsprechend der Brandwiderstandsklasse F90, hochbrandhemmend entsprechend der Brandwiderstandsklasse F60, mit geringer Qualmbildung (Qualmbildungsklasse Q1) und kleiner Tropfenbildung (Tropfenbildungsklasse Tr1) ist, sowie eine gute schallschluckende Wirkung besitzt.The tests showed that the insulation and fire protection compound produced from the above-mentioned materials by the process according to the invention is fire-resistant in accordance with fire resistance class F90, highly fire-retardant in accordance with fire resistance class F60, with low smoke formation (smoke formation class Q1) and small drop formation (drop formation class Tr1), as well as good has a sound-absorbing effect.

Bei weiteren Versuchen mit dieser Dämm-und Brandschutzmasse wurden neben den guten Brandschutzeigenschaften und den guten schall- und Lärmschutzeigenschaften auch die Eignung als Warme- oder Kälteisolierung festgestellt.In further tests with this insulation and fire protection compound, in addition to the good fire protection properties and the good sound and noise protection properties, the suitability as warm or cold insulation was also established.
