Description

"Schlauch" "Tube"
Die Erfindung betrifft einen Schlauch, insbesondere zum Durchleiten aggressiver Flüssigkeiten, mit einem Aufbau aus natürlichem oder synthetischem Gummi materi al , in das gege¬ benenfalls Verstärkungslagen eingearbeitet sind, sowie einer Innenschicht aus Fluorkunststoff.The invention relates to a hose, in particular for the passage of aggressive liquids, with a structure made of natural or synthetic rubber material, into which reinforcement layers are optionally incorporated, and an inner layer made of fluoroplastic.
Um aggressive Flüssigkeiten, wie Säuren, Laugen, Lösungs- itte! oder dergleichen, fördern zu können, müssen Schläu¬ che mit einer chemisch beständigen Innenschicht ausgeklei¬ det sein. Diese Innenschicht soll aber so gestaltet sein, daß die guten Eigenschaften von Schl uchen, wie Flexibili¬ tät, Druckfestigkeit, Saugfestigkeit und dergleichen, er- halten bl ei ben .To aggressive liquids such as acids, bases, solvents! or the like to be able to promote, hoses must be lined with a chemically resistant inner layer. This inner layer should, however, be designed in such a way that the good properties of hoses, such as flexibility, compressive strength, suction strength and the like, are retained.
Fluorkunststoff hat sich als Innenschicht bereits bestens bewährt, da er gegen eine große Anzahl verschiedenster aggressiver Medien resistent ist.Fluoroplastic has already proven its worth as an inner layer because it is resistant to a large number of different aggressive media.
Andererseits ist aber Fluorkunststoff äußerst schwierig zu verarbeiten, und er hat insbesondere gegenüber den ver¬ schiedensten Gummimaterialien eine nur geringe Haftfähig¬ keit .On the other hand, however, fluoroplastic is extremely difficult to process, and it has only a low level of adhesion, in particular in relation to a wide variety of rubber materials.
Aus der EU-OS 0 222 323 ist es bekannt, die Innenschicht aus Fluorkunststoff dadurch an der Innenwand eines Gummi- schlauchs zu befestigen, daß zwischen die Gummi i nnenwand und die Innenschicht aus Fluorkunststoff ein textiles Flä¬ chengebilde eingebettet wird. Die F den und Fasern des textilen Flächengebildes sollen dabei einerseits von dem Material der Innenschicht und andererseits von dem Gum i- aterial des Schi auchaufbaus räumlich hinter- bzw. umfaßt werden. Eine derartige, im wesentlichen auf einer mechani¬ schen Verankerung beruhende Erfindung ist jedoch nicht immer ausreichend;- insbesondere bei Temperaturerhöhungen dürfte eine solche bekannte Verbindung zu schwach sein. Darüber hinaus ist die Herstellung einer solchen Verbindung mit einem erheblichen Aufwand verbunden.It is known from EU-OS 0 222 323 that the inner layer made of fluoroplastic is thereby attached to the inner wall of a rubber to attach the hose so that a textile fabric is embedded between the rubber inner wall and the inner layer made of fluoroplastic. The threads and fibers of the textile fabric should be spatially behind or encompassed on the one hand by the material of the inner layer and on the other hand by the rubber of the ski structure. However, such an invention, which is essentially based on mechanical anchoring, is not always sufficient; in particular when the temperature rises, such a known connection should be too weak. In addition, the establishment of such a connection is associated with considerable effort.
Der Erfindung liegt die Aufgabe zugrunde, das Haftsystem zwischen der Innenschicht aus Fluorkunststoff und der Innenfläche des Seh 1 auchaufbaus zu verbessern und insbeson¬ dere den Herstellungsaufwand eines mit einer Fluorkunst¬ stoff-Innenschicht versehenen Schlauches zu reduzieren.The object of the invention is to improve the adhesive system between the inner layer made of fluoroplastic and the inner surface of the sight 1, and in particular to reduce the production outlay of a hose provided with a fluoroplastic inner layer.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß zwischen der Innenschicht und dem Aufbau des Schlauches eine Schicht aus einer Haftmischung vorgesehen ist, die aus Elastomeren sowie Zuschlagstoffen besteht, und daß die Haftmischungsschicht über ein Haftmittel mit der Innen¬ schicht verbunden ist.According to the invention, this object is achieved in that a layer of an adhesive mixture is provided between the inner layer and the structure of the hose, which layer consists of elastomers and additives, and that the adhesive mixture layer is connected to the inner layer via an adhesive.
Durch das erfindungsgemäße Haftsystem wird die Dehäsion des Fluorkunststoffes gegenüber dem Gummimaterial des Schlauch¬ aufbaus äußerst wirksam überwunden, und es wird ein guter Verbund erzielt, der mit relativ geringem Aufwand herstell¬ bar ist.The adhesion system according to the invention overcomes the adhesion of the fluoroplastic with respect to the rubber material of the tube structure extremely effectively, and a good bond is achieved which can be produced with relatively little effort.
Die Haftmischungsschicht und das Gummimaterial des Schi auchaufbaus sind vorzugsweise durch Vulkanisation mit¬ einander verbunden, wodurch ein inniger Verbund entsteht.The adhesive mixture layer and the rubber material of the ski structure are preferably connected to one another by vulcanization, as a result of which an intimate bond is created.
Als Material für die Haftmischungsschicht eignet sich ins- besondere natürlicher oder synthetischer Kautschuk, der Alterungsschutzmittel, Weichmacher sowie Vulkanisations¬ mittel enthäl t .Suitable material for the adhesive mixture layer is special natural or synthetic rubber which contains anti-aging agents, plasticizers and vulcanizing agents.
Vorzugsweise wird bei der Haftmischungsschicht als Kautschuk hal ogeni erter Butyl kautschuk , beispielsweise Chlorbutyl kautschuk , verwendet.Preferably, halogenated butyl rubber, for example chlorobutyl rubber, is used as the rubber in the adhesive mixture layer.
Als Füllstoffe werden in der Haftmischung zweckmäßig helle Füllstoffe verwendet, durch die die Haftfähigkeit der Haft¬ mischung noch verbessert werden kann.Bright fillers are expediently used as fillers in the adhesive mixture, by means of which the adhesiveness of the adhesive mixture can be further improved.
Zur weiteren Verbesserung, insbesondere zwischen der Haft¬ mischungsschicht und der Innenschicht, kann die Haft¬ mischungsschicht Resorcin und Formaldehydspenderkomponenten enthal ten .For further improvement, in particular between the adhesive mixture layer and the inner layer, the adhesive mixture layer can contain resorcinol and formaldehyde donor components.
Die Haftmischungsschicht braucht nur relativ dünn ausgebil¬ det zu sein. Es genügt eine Schichtdicke von etwa 0,2 bis 2 mm.The adhesive mixture layer need only be made relatively thin. A layer thickness of approximately 0.2 to 2 mm is sufficient.
Als Haftmittel werden zweckmäßig Substanzen mit freien Iso- cyanatgruppen verwendet.Substances with free isocyanate groups are expediently used as adhesives.
Vorzugsweise werden hochaktive Polyi socyanate eingesetzt, beispielsweise in Form einer 20 %igen Lösung von Triphenyl- ethantri i socyanat in Methylenchlorid. Ein solches Haft¬ mittel kann auf die Innenschicht leicht aufgetragen werden.Highly active polyisocyanates are preferably used, for example in the form of a 20% solution of triphenylethane triisocyanate in methylene chloride. Such an adhesive can easily be applied to the inner layer.
Für die aus Fluorkunststoff bestehende Innenschicht wird zweckmäßig Folienmaterial verwendet. Das Folienmater al weist vorzugsweise eine Dicke von 0,02 bis 1 mm auf.Foil material is expediently used for the inner layer consisting of fluoroplastic. The foil material al preferably has a thickness of 0.02 to 1 mm.
Die Erfindung ist in der Zeichnung beispielsweise veran- schaulicht und im nachstehenden im einzelnen anhand der Zeichnung beschrieben. In der Zeichnung ist ein Teilschnitt durch einen Schlauch 1 dargestel 1 t .The invention is illustrated in the drawing, for example, and described in detail below with reference to the drawing. In the drawing, a partial section through a hose 1 is shown 1 t.
Der Schlauch 1 kann in beliebiger herkömmlicher Weise auf¬ gebaut sein, und zwar aus einer Decke 2, einer Seele 3 sowie mehreren zwischen diesen angeordneten Verstärkungs¬ lagen 4 aus Textil- und/oder Stahlkord und gegebenenfalls einer eingearbeiteten Stahl- oder Kunststoffschrauben- wendel .The hose 1 can be constructed in any conventional manner, namely from a blanket 2, a core 3 and a plurality of reinforcing layers 4 of textile and / or steel cord arranged between them, and optionally a built-in steel or plastic screw helix.
Der Schlauch ist mit einer Innenschicht 5 aus Fluorkunst¬ stoff versehen, die aus Folienmaterial mit einer Dicke von etwa 0,02 bis 1 mm besteht.The hose is provided with an inner layer 5 made of fluoroplastic, which consists of film material with a thickness of approximately 0.02 to 1 mm.
Zwischen der Innenschicht 5 und der Seele 3 des Schlauchs 1 ist ein Haftsystem vorgesehen, welches die Dehäsion zwi¬ schen Fluorkunststoff und Gummi überwindet.An adhesive system is provided between the inner layer 5 and the core 3 of the hose 1, which overcomes the adhesion between fluoroplastic and rubber.
Als Haftsystem dient eine Schicht 6 aus einer Haftmischung, die über der Innenschicht 5 aufgebracht wird. Die Haft¬ mischung besteht aus natürlichem oder synthetischem Kautschuk, welcher Alterungsschutzmittel, Weichmacher sowie Vulkanisationsmittel enthält.A layer 6 made of an adhesive mixture, which is applied over the inner layer 5, serves as the adhesive system. The adhesive mixture consists of natural or synthetic rubber, which contains anti-aging agents, plasticizers and vulcanizing agents.
Vor dem Aufbringen der Haf mischungsschicht 6 wird auf die Innenschicht 5 ein Haftmittel 7 aufgetragen, beispielsweise eine 20 %ige Lösung von Tri phenylmethantri i socyanat in Methylenchlorid. Durch dieses Haftmittel wird die Haft¬ fähigkeit zwischen der Innenschicht 5 und der Haft- mi schungsschicht 6 so weit erhöht, daß eine Trennung der Innenschicht 5 und der Haftmischungsschicht 6 selbst unter extremen Bedingungen nicht zu erwarten ist.Before the adhesive mixture layer 6 is applied, an adhesive 7 is applied to the inner layer 5, for example a 20% strength solution of tri phenylmethane tri iocyanate in methylene chloride. This adhesive increases the adhesiveness between the inner layer 5 and the adhesive mixture layer 6 to such an extent that separation of the inner layer 5 and the adhesive mixture layer 6 is not to be expected even under extreme conditions.
Das über der Haftmischungsschicht 6 aufgebrachte Gummi ate- rial des Schi auchaufbaus wird an die Haftmischungsschicht 6 anvulkanisiert, wodurch eine innige Verbindung zwischen derThe rubber applied above the adhesive mixture layer 6 of the ski structure is vulcanized onto the adhesive mixture layer 6, as a result of which an intimate connection between the
Haftmischungsschicht 6 und den darüberl i egenden Schichten geschaffen wird.Adhesive mixture layer 6 and the overlying layers is created.
Die Herstellung des Schlauchs wird folgendermaßen durch¬ geführt :The hose is produced as follows:
Zunächst wird zur Herstellung der Innenschicht 5 eine Folie aus Fluorkunststoff, die eine Dicke von 0,02 bis 1 mm auf¬ weist, schraubenl i ni enförmi g auf einem Dorn aufgewickelt, wobei sich die übereinanderliegenden Ränder der Folie in einer Breite von 5 bis 6 mm überlappen.First, to produce the inner layer 5, a film made of fluoroplastic, which has a thickness of 0.02 to 1 mm, is wound helically on a mandrel, the edges of the film lying one above the other having a width of 5 to 6 mm overlap.
Nach Herstellung der Innenschicht 5 wird das Haftmittel 7 aufgetragen. Das Auftragen kann mit Hilfe eines Pinsels oder dergleichen erfolgen.After the inner layer 5 has been produced, the adhesive 7 is applied. The application can be done with the help of a brush or the like.
Auf die so vorbereitete Innenschicht 5 wird die Haft¬ mischungsschicht 6 in einer Schichtstärke von etwa 0,2 bis 2 mm aufgebracht. Beispielsweise besteht die Haftmischungs¬ schicht aus Chl orbutyl kautschuk, dem helle Füllstoffe, Alterungsschutzmittel , Weichmacher, Vul anisationsmittel sowie ein Haftvermittler beigefügt sind.The adhesive mixture layer 6 is applied in a layer thickness of approximately 0.2 to 2 mm to the inner layer 5 prepared in this way. For example, the adhesive mixture layer consists of chlorobutyl rubber, to which light fillers, anti-aging agents, plasticizers, vulcanizing agents and an adhesion promoter are added.
Die so vorbehandelte Innenschicht aus Fluorkunststoff wird anschließend bei Schmelztemperatur des Fluorkunststoffs unter Druck vulkanisiert. Dabei wird einerseits eine innige Verschweißung der sich überlappenden Folie der Innenschicht 5 erreicht, und zum anderen wird unter Vermittlung des Haftmittels 7 eine dauerhafte und gute Bindung zwischen der Innenschicht 5 und der Haftmischungsschicht 6 erzielt.The inner layer made of fluoroplastic pretreated in this way is then vulcanized under pressure at the melting temperature of the fluoroplastic. On the one hand an intimate welding of the overlapping film of the inner layer 5 is achieved, and on the other hand a permanent and good bond between the inner layer 5 and the adhesive mixture layer 6 is achieved by means of the adhesive 7.
Nach diesem Behandlungsschritt werden auf die Haft¬ mischungsschicht 6 die übrigen Lagen des Schi auchaufbaus aufgebracht, und zwar die Seele 3, die Verstärkungslagen 4 sowie die Decke 2. Die Gesamtheit der Lagen wird anschlie- • ßend vulkanisiert. After this treatment step are mixed layer on the Haft¬ 6, the remaining layers of the ski structure also applied, namely, the core 3, the reinforcing layers 4 and the ceiling 2. The entirety of the layers is vulcanized ßend subse- •.
