Description
Verfahren zur Erzielung einer elastischen Verbindung von Schaumgummiflächen vermittels eines Klebstoffes Die hohe Elastizität des Schaumgummis beruht auf seinen vielen unregelmäßigen Hohlräumen in seiner Masse. Bei der Verbindung von Schaumgummiflächen. mittels flüssiger Klebstoffe dringen an den Auftragsflächen infolge der Kapiflarwirkung der Hohlräume größere Mengen Klebstoff tief in das Innere des Schaumgummis ein. Dadurch geht nach dem Verkleben an der Verbindungsfläche die Elastizität des Schaumgummis verloren, indem sich je nach Klebstoffa,rt und Viskosität desselben nach dem Aus trocknen entweder scharfe steife Flächen ausbilden oder unelastische Wülste unter Volumenverminderung auftreten. Die Anwendung von Vullçanisationslösungen bewirkt wohl eine wesentlich bessere Elastizität der Verb,inYlungsflächen, erfordert jedoch entweder mehrere Tage zur Vulkanisation bei Zimmertemperatur, während welcher Zeit die Verbindungsstellen unbelastet und vor jedem Druck geschützt sein müssen, oder man muß besondere Arbeitsgänge zur Heißvul kanisation anwenden.Process for achieving an elastic connection between foam rubber surfaces by means of an adhesive The high elasticity of the foam rubber is due to its many irregular voids in its mass. When connecting foam rubber surfaces. by means of liquid adhesives penetrate the application surfaces as a result of the Kapiflar effect The cavities allow larger amounts of glue to penetrate deep into the interior of the foam rubber. As a result, the elasticity of the foam rubber goes down after gluing at the connection surface lost, depending on the adhesive type and viscosity of the same after the end dry either sharp, rigid surfaces or inelastic bulges under them Volume decrease occur. The application of Vullçanization solutions causes probably a much better elasticity of the verb, inYlungsflächen, requires, however either several days for vulcanization at room temperature, during which time the connection points must be unloaded and protected from any pressure, or you have to use special operations for hot vulcanization.
Demgegenüber bringt die Erfindaing dadurch besondère Vorteile, daß die Erzielung einer elastischen Klebeverbin dung durch zwei unmittelbar aufeinanderfol-gende Arbeitsgänge bewerkstelligt wird und nach einer Trocknungszeit von wem gen Stunden bei Zimmertemperatur die Verbindungsstellen bereits normal auf Zug oder Druck belastet werden können. Eine besondere Bedeutung kommt hiernach dem Verfahren für die Aufarbeitung von Schaumgummiabfällen zu geschlossenen Massen für neue Verwendung zu. In contrast, the invention has particular advantages that the achievement of an elastic adhesive connection through two immediately following one another Operations is accomplished and after a drying time of whom gen hours at room temperature the connection points are already normal to tension or pressure burdened can be. The process for reconditioning is of particular importance from foam rubber waste to closed masses for new uses too.
Nach der Erfindung werden die zu verkleben den Stellen mit einer gegenüber der Gummimasse indifferenten Flüssigkeit, vorzugsweise Wasser, benetzt und nach Troden ihrer Oberfläche mit Klebstoff verbunden, so daß vor dem eigenttichenKlebevorgang die Hohlräume in der Nähe der Verbindungsflächen mit einer Flüssigkeit ausgefüllt oder benetzt sind, in der sich der angewendete Klebstoff nicht lösen darf. Hierdurch wird einerseits ein Eindringen von Klebstoffteilen in das Innere des Schaumgummis verhindert, andererseits der Klebstoff seiner Fähigkeit beraubt, Klebeverbindungen herzustellen. Lediglich an der Oberfläche der zu verbindenden Flächen ist nach oberflächlichem Austrocknen der Benetzungsflüssiglçeit dem Klebstoff die Möglichkeit gegeben, seine Wirkung zu entfalten. Der gesamte Klebstoff hat endgültig abgebunden, bevor die Benetzuugsflüssigkeit aus dem Inneren des Schaumgummis verdunstet ist. Die verbleibende geringe Beeinträchtigung der Elastizität ist praktisch ohne Bedeutung und nicht größer als diejenige bei Anwendung von Vulkanisationsmitteln. Bei Anwendung der Erfindung zur Herstellung von Schaumgummimassen aus Schaumgummiabfällen büßt das verarbeitete Material nur wenig an Elastizität ein und ist für viele Zwecke als billiger Rohstoff wirtschaftlich verwertbar. According to the invention, the places to be glued with a liquid, preferably water, which is indifferent to the rubber compound and bonded with glue after trotting their surface, so that before the actual gluing process the cavities in the vicinity of the connecting surfaces are filled with a liquid or are wetted, in which the adhesive used must not loosen. Through this On the one hand, there is a penetration of adhesive parts into the interior of the foam rubber prevents, on the other hand, the adhesive robs of its ability to create adhesive bonds to manufacture. Only on the surface of the surfaces to be connected is superficial Drying out of the wetting liquid gave the adhesive the opportunity to do its job To make an impact. All of the glue has finally set before the Wetting liquid has evaporated from inside the foam rubber. The remaining slight impairment of elasticity is practically insignificant and not greater than that when using vulcanizing agents. When using the Invention for the production of foam rubber compounds from foam rubber waste loses this Processed material has little elasticity and is considered for many purposes cheap raw material economically usable.
Beispiel I Zwei zu verklebende Schaumgummiflächen werden mittels eines Schwammes mit Wasser benetzt, worauf nach Ablauf von wenigen Sekunden die Flächen mit einem füllstofffreien Klebstoff dünn bestrichen werden, der als Lösungsmittel Kohlenwassersktoffe enthält. Nach einer Antrockenzeit von 2 bis 5 Minuten werden die bestrichenen Flächen mit leichtem Druck zusammengefügt. Example I Two foam rubber surfaces to be glued are made by means of a sponge wetted with water, whereupon after a few seconds the Surfaces are coated thinly with a filler-free adhesive that acts as a solvent Contains hydrocarbons. After a drying time of 2 to 5 minutes the painted areas joined together with light pressure.
Nach Ablauf von etwa 6 Stunden ist eine feste elastische Klebeverbindung entstanden, die bereits vor dem endgültigen Abbinden des Klebstoffes und Austrochnung des Wassers normal auf Zug oder Druck belastet werden kann.After about 6 hours there is a firm, elastic adhesive bond originated before the final setting of the adhesive and drying out of the water can normally be subjected to tension or pressure.
Beispiel II Feinzerrissenes Schaumgummiabfallmaterial wird durch Düsen mit Wass!er benetzt und darauf einem Luftstrom zur oberflächlichen Abtrocknung ausgesetzt. Hierauf wird das Material mit einem füllstofffreien Klebstoff in feinverteilter Form besprüht, worauf die Massen entweder in Formen oder als Platten unter leichtem Druck getrocknet werden. Example II Finely shredded foam rubber waste material is made by Nozzles wetted with water and then a stream of air for superficial drying exposed. The material is then finely divided with a filler-free adhesive Sprayed form, whereupon the masses either in forms or as plates under light Print to be dried.
