Description
Die Erfindung betrifft einen schlauchförmigen Körper aus elastomerem Werkstoff, wobei in die Schlauchwandung eine oder mehrere Lagen einer Folie als Diffusionssperrschicht, die mit einem Haftvermittler versehen ist, eingearbeitet ist.The invention relates to a tubular body made of elastomeric material, wherein in the hose wall one or more layers of a film as Diffusion barrier layer, which is provided with an adhesion promoter, is incorporated.
Schlauchförmige Körper, beispielsweise Schläuche und Kompensatoren, werden beim Transport zahlreicher Medien eingesetzt. Die Beständigkeit gegen diese Medien wird dabei durch die geeignete Wahl einer Gummimischung gewährleistet. Problematisch bleibt aber in vielen Fällen der Austritt des Mediums durch Diffusion durch die Wandung des Körpers.Tubular bodies, such as hoses and expansion joints, are used in Transport of numerous media used. The resistance to these media will guaranteed by the appropriate choice of a rubber compound. Problematic In many cases, however, the medium remains through diffusion through the medium Wall of the body.
Es ist nun bekannt, Schläuche zwecks Verringerung des Diffusionsverlustes mit einer geschlossenen Schlauchfolie auszukleiden bzw. zu ummanteln, wobei insbesondere auf folgenden Stand der Technik verwiesen wird.It is now known to reduce the diffusion loss hoses with a lining or sheathing closed tubular film, in particular reference is made to the following prior art.
In der Patentschrift EP 0 222 323 B1 wird ein gattungsgemäßer Schlauch vorgestellt, der mit einer fluorhaltigen Auskleidungsfolie versehen ist. Ein textiles Geflecht übernimmt dabei die Rolle des Haftvermittlers zwischen der Auskleidungsfolie und der Schlauchinnenwand. Dabei werden die innenliegenden Fadenabschnitte bzw. die Fasern des Geflechtes mindestens teilweise von dem fluorhaltigen Kunststoff der Auskleidungsfolie umschmolzen.In the patent EP 0 222 323 B1 a generic hose is presented, which is provided with a fluorine-containing lining film. A textile mesh assumes the role of adhesion promoter between the lining film and the Inner hose wall. The inner thread sections or the Fibers of the braid at least partially from the fluorine-containing plastic Lining foil melted.
Nachteilig ist, daß dieses Konzept nur auf Kunststoffe anwendbar ist, die einen schlauchtechnisch realisierbaren Schmelzpunkt aufweisen, der insbesondere bei höchstens 170°C liegt. Darüber hinaus sind wegen der Geflechtskonstruktion des Haftvermittlers der Formgebung, beispielsweise bei Kompensatoren, enge Grenzen gesetzt. The disadvantage is that this concept is only applicable to plastics that have one Have a melting point that can be realized in terms of hose technology, in particular at is at most 170 ° C. In addition, because of the braid construction of the Adhesion promoter of the design, for example in expansion joints, narrow limits set.
Hinsichtlich schlauchförmiger Körper aus Kunststoff, insbesondere auf der Basis fluorhaltiger Kunststoffe, wird ergänzend noch auf die Offenlegungsschrift DE 27 28 636 A1 verwiesen.With regard to tubular bodies made of plastic, in particular on a base fluorine-containing plastics, reference is also made to the laid-open specification Reference is made to DE 27 28 636 A1.
Die Aufgabe der Erfindung besteht nun darin, einen gattungsgemäßen schlauchförmigen Körper bereitzustellen, dessen Diffusionssperrschicht einer breiten Werkstofftechnologie zugängig ist und dessen Haftvermittler so gestaltet ist, daß selbst bei Kompensatoren, auf die erhebliche Kräfte axialer und/oder lateraler und/oder angularer Art wirken, eine sichere Haftung der Diffusionssperrschicht gewährleistet ist.The object of the invention is now to provide a generic provide tubular body, the diffusion barrier layer of a wide Material technology is accessible and its adhesion promoter is designed so that even in the case of expansion joints, which are subject to considerable axial and / or lateral and / or forces act angular kind, a secure adhesion of the diffusion barrier layer is guaranteed.
Gelöst wird diese Aufgabe gemäß Kennzeichen des Patentanspruches 1 dadurch, daß
der Haftvermittler eine Haftmischung auf Basis von Nitrilkautschuk (NBR),
Polychloropren (CR) oder Ethylen-Propylen-Dien-Mischpolymerisat (EPDM) sowie
Verschnitten aus NBR/CR oder EPDM/NBR ist, wobei die Haftmischung aus den
folgenden Bestandteilen (in phr) aufgebaut ist:
This object is achieved according to the characterizing part of patent claim 1 in that the adhesion promoter is an adhesion mixture based on nitrile rubber (NBR), polychloroprene (CR) or ethylene-propylene-diene copolymer (EPDM) and blends of NBR / CR or EPDM / NBR , whereby the adhesive mixture is made up of the following components (in phr):
Zweckmäßige Ausgestaltungen des schlauchförmigen Körpers sind in den Patentansprüchen 2 bis 6 genannt.Appropriate configurations of the tubular body are in the Claims 2 to 6 called.
Eine weitere Aufgabe der Erfindung besteht darin, ein Verfahren zur Herstellung des erfindungsgemäßen schlauchförmigen Körpers bereitzustellen, wobei der wesentliche Verfahrensschritt gemäß Patentanspruch 7 darin besteht, daß ein mit der Haftmischung versehener Folienstreifen wendelförmig in einer oder mehreren Lagen überlappend auf einen formgegebenen Körper aufgewickelt wird.Another object of the invention is to provide a method for producing the to provide tubular body according to the invention, the essential Method step according to claim 7 is that one with the adhesive mixture provided film strip helically overlapping in one or more layers a shaped body is wound up.
Im folgenden wird nun das Verfahren zur Herstellung eines öl- und
kraftstoffbeständigen Kompensators mit einer Diffusionssperrschicht aus Polyamidfolie
beschrieben. Die einzelnen Verfahrensschritte sind:
In the following, the method for producing an oil- and fuel-resistant compensator with a diffusion barrier layer made of polyamide film will now be described. The individual process steps are:
- - Zunächst wird eine Gummimischung bereitgestellt, die gute Haftung zur Polyamidfolie nach der Vulkanisation hat und gute Konfektionsklebrikeit zu dieser Folie besitzt.- First a rubber compound is provided, the good adhesion to the polyamide film after vulcanization and good adhesive strength to this film owns.
- - Die Haftmischung wird als dünne Platte (0,5-0,9 mm) kalandriert und zusammen mit der Polyamidfolie dubliert.- The adhesive mixture is supplied as a thin plate (0.5-0.9 mm) calendered and duplicated together with the polyamide film.
- - Die zugeschnittene gummierte Folie wird in zwei Schichten auf die Wickeltrommel aufgewickelt und bildet die innere Schicht des Kompensators. Die Folienseite muß dabei auf der Wickeltrommel liegen.- The cut rubberized film is cut in two Layers wound on the winding drum and forms the inner layer of the compensator. The foil side must lie on the winding drum.
- - Danach erfolgt der weitere Aufbau (Gewebeeinlagen, obere Schicht) je nach Spezifikation.- This is followed by the further construction (fabric inserts, upper layer) depending on the specification.
- - Der Rohling wird vulkanisiert.- The blank is vulcanized.
- - Nach der Vulkanisation ist die innere Seite des Kompensators mit der Polyamidfolie ausgekleidet. Diese Folie schützt die unterliegende Gummimischung (Außenschicht) vor dem Einfluß von Kraftstoff und Ölen.- After vulcanization, the inner side of the Compensator lined with the polyamide film. These Foil protects the underlying rubber compound (Outer layer) from the influence of fuel and Oil.
