Abstract

The invention relates to a method and a device for producing reactive adhesives having at least two components, for example adhesives with moisture-activated cross-linking. According to said method at least one non-reactive adhesive component present in solid form, for example a granulate (G), or liquid form (F) and at least one reactive adhesive component present in the form of a solid, for example a granulate (G), or a liquid (F), are used. The two adhesive components are heated by pressure and friction in an endless screw in a specific proportion and mixed to produce the liquid reactive adhesive (K). The liquid reactive adhesive (K) is then applied directly to the area of application (use).

Description

Verfahren und Vorrichtung zur Herstellung von zweikomponentigen reaktiven KlebstoffenMethod and device for producing two-component reactive adhesives

Die Erfindung betrifft ein Verfahren zur Herstellung mindestens zweikomponentiger reaktiver Klebstoffe und einer anschließend integrierten Vorrichtung zur Verarbeitung des z.B. feuchtigkeitsreaktiven Klebstoffes .The invention relates to a method for producing at least two-component reactive adhesives and a subsequently integrated device for processing the e.g. moisture-reactive adhesive.

In der Praxis ist es bekannt, reaktive Klebstoffe aus zwei oder mehreren Komponenten unter Wärmeeinwirkung und durch Mischen zu einer flüssigen Masse zu bringen, diese dann anschließend unter jeglichem Ausschluß von Luftfeuchtigkeit in einem Behältnis gasdicht zu verpacken; danach erfolgt die Abkühlung, so daß der vakuumverpackte reaktive Klebestoff in verfestigter Form in dem Behälter gelagert und transportiert werden kann. Die gewünschte Verarbeitung wird in bekannten Vorschmelzgeräten, in denen der Klebestoff wieder aufgeschmolzen und dann für die Applikation eingesetzt wird, vorgenommen.In practice, it is known to bring reactive adhesives from two or more components under the action of heat and by mixing to a liquid mass, which is then packaged in a gas-tight manner with any exclusion of atmospheric moisture; cooling then takes place so that the vacuum-packed reactive adhesive can be stored and transported in solidified form in the container. The desired processing is carried out in known premelting devices, in which the adhesive is melted again and then used for the application.

Nachteilig hierbei sind die verhältnismäßig hohen Herstellungkosten, mögliche Beschädigung beim Transport der den abgefüllten reaktiven Klebstoff beinhaltenden Behälter und Haltbarkeit des reaktiven Klebstoffes durch Undichtigkeit der Verpackung aufgrund längerer Transport- oder Lagerzeiten. Nach Öffnen der Behälter reagiert die Oberfläche des reaktiven Klebstoffes und bei längerer Standzeit wird dadurch der reaktive - 2 -Disadvantages here are the relatively high production costs, possible damage during transport of the containers containing the filled reactive adhesive and durability of the reactive adhesive due to leakage of the packaging due to longer transport or storage times. After opening the container, the surface of the reactive adhesive reacts and, if it remains for a longer period of time, it becomes reactive - 2 -

Klebstoff unbrauchbar. Dieses führt zu Rückläufen des reaktiven Klebstoffes, was natürlich wiederum mit Kosten verbunden ist. Reaktiver Klebstoff, der aus einem Faß nicht vollständig verarbeitet wird und stehenbleibt, wird unbrauchbar.Glue unusable. This leads to returns of the reactive adhesive, which is of course associated with costs. Reactive adhesive that is not completely processed from a barrel and remains standing becomes unusable.

Nach Beendigung des Herstellungsverfahrens des reaktiven Klebstoffes beginnt praktisch die Laufzeit der Haltbarkeit, und diese ist entscheidend für die optimale Nutzung des reaktiven Klebstoffes. Bei den mit Feuchtigkeit vernetzenden Klebstoffen wird die chemische Vernetzungsreaktion durch Luftfeuchtigkeit, aber auch durch die ständige Einwirkung von Temperatur während der Vor- und Aufschmelzphase bis zur Applikation ausgelöst.After the manufacturing process of the reactive adhesive has ended, the shelf life practically begins, and this is decisive for the optimal use of the reactive adhesive. In the case of adhesives that crosslink with moisture, the chemical crosslinking reaction is triggered by atmospheric moisture, but also by the constant action of temperature during the pre- and melting phase until application.

Aufgabe der Erfindung ist es, ein Verfahren zu schaffen, mit welchem ein reaktiver Klebstoff aus getrennt und unbegrenzt haltbar lagerfähigen Komponenten in einem Arbeitsgang mit unmittelbar nachfolgender Verarbeitung/Applikation erzielt wird, wobei Ausschüsse an Klebstoff und damit zusätzliche Kosten vermieden werden.The object of the invention is to provide a method with which a reactive adhesive consisting of separately and indefinitely storable components can be achieved in one work step with immediately subsequent processing / application, with rejects of adhesive and thus additional costs being avoided.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst; die sich daran anschließenden Verfahrensansprüche bilden vorteilhafte Weiterbildungen der Aufgabenlösung.This object is achieved by the characterizing features of claim 1; the subsequent process claims form advantageous developments of the task solution.

Eine weitere Aufgabe wird in der Schaffung einer einfach und kostengünstig aufgebauten und wirtschaftlich arbeitenden Vorrichtung gesehen, mit der für die jeweilige Applikation ohne Zwischenstationen und -lagerung gebrauchsfertige reaktive Klebstoffe hergestellt werden können. - 3Another task is seen in the creation of a simple and cost-effective and economically working device with which ready-to-use reactive adhesives can be produced for the respective application without intermediate stations and storage. - 3rd

Diese Aufgabe lösen die Vorrichtungsmerkmale nach Anspruch 6 und vorteilhafte Weiterbildungen in den anderen Vorrichtungsansprüchen.This object is achieved by the device features according to claim 6 and advantageous developments in the other device claims.

Die Bestandteile des reaktiven Klebestoffs, also seine Komponenten, werden voneinander getrennt gelagert, so daß keine vorzeitige Berührung erfolgt und dadurch eine unbegrenzte Haltbarkeit und Lagerzeit dieser Komponenten erreicht wird. Dadurch sind die Verfahrenswege zur Herstellung wesentlich einfacher als bisher, bezogen auf die einzelnen Komponenten.The components of the reactive adhesive, that is to say its components, are stored separately from one another so that they do not come into contact prematurely and, as a result, these components have an unlimited shelf life and storage time. As a result, the manufacturing processes are much simpler than before, based on the individual components.

Der Klebstoff besteht aus mindestens einem Teil der nicht reaktiven Komponente (n) , wie z.B. funktionalisierte Polymere und Harzmischungen, aber auch anderen, und mindestens einem zweiten Teil, bestehend aus der reaktiven Komponente, wie z.B. Polyisocyanate und anderen.The adhesive consists of at least part of the non-reactive component (s), e.g. functionalized polymers and resin blends, but also others, and at least a second part consisting of the reactive component, such as e.g. Polyisocyanates and others.

Die beiden oder auch mehreren Komponenten des herzustellenden Klebstoffes werden in fester oder flüssiger Form in einen Extruder gegeben, wobei mindestens eine Komponente entsprechend dem Klebstoff-Mischverhältnis dosiert zugegeben wird. Die beiden oder mehreren zu mischenden Komponenten stehen in einem bestimmten Verhältnis zueinander, was abhängig ist vom chemischen Aufbau und vom späteren Verwendungszweck des Klebstoffes. Die zugeführten Komponenten des Klebstoffes werden in den Extruder gegeben und durch Friktion und Druck erhitzt. Für die Erwärmung des Klebstoffes reicht die Friktion und der Druck aus. Zusätzlich kann noch eine Beheizung erfolgen, die auch später beim erneuten Anfahren und Stillstand der Mischschnecke des Extruders zum Tragen kommt. Der Extruder bildet den Vorschmelzer, der die Komponenten in einem Durchgang mischt und zu dem gebrauchsfähigen und sofort verarbeitbaren reaktiven Klebstoff herstellt. 4 -The two or more components of the adhesive to be produced are added in solid or liquid form to an extruder, at least one component being metered in according to the adhesive mixing ratio. The two or more components to be mixed are in a certain relationship to one another, which depends on the chemical structure and the later intended use of the adhesive. The supplied components of the adhesive are placed in the extruder and heated by friction and pressure. The friction and pressure are sufficient to heat the adhesive. In addition, heating can also take place, which also comes into play later when the extruder mixing screw is restarted and stopped. The extruder forms the pre-melter, which mixes the components in one pass and produces them into the ready-to-use and immediately processable reactive adhesive. 4 -

Es wird immer nur soviel reaktiver Klebstoff gemischt, hergestellt und aufgeschmolzen, wie für den jeweiligen Einsatzfall gerade gebraucht wird. Bisher werden große Mengen abgefüllt und müssen komplett verarbeitet werden. Der Nachteil hierbei ist, wenn die Auftragsmenge nicht benötigt wird, entsteht Abfall, während bei dem erfindungsgemäßen neuen Verfahren es so ist, daß nur die gezielte Menge hergestellt wird, die auch benötigt wird.Only as much reactive adhesive is mixed, manufactured and melted as is needed for the respective application. So far, large quantities have been filled and have to be processed completely. The disadvantage here is that waste is generated when the order quantity is not required, whereas in the novel method according to the invention it is the case that only the targeted quantity is produced which is also required.

Der Reinigungsprozeß stellt sich auch ganz einfach dar, indem die reaktive (n) Komponente (n) abgeschaltet wird (werden) und die andere (n) , nicht reaktive (n) Komponente (n) zum Spülen der Aufschmelzsysteme bzw. Auftragssysteme eingesetzt wird (werden) . The cleaning process is also very simple, in that the reactive component (s) is (are) switched off and the other, non-reactive (s) component (s) is used to rinse the melting systems or application systems ( become) .
