Description

Die Erfindung betrifft einen Artikel mit einem Grundkörper aus einem polymeren Werkstoff mit elastischen Eigenschaften, insbesondere einen Luftfederbalg.The invention relates to an article with a base body made of a polymer material with elastic properties, in particular an air spring bellows.

Artikel aus polymeren Werkstoffen, die zur Federung bspw. von Kraftfahrzeugen oder Schienenfahrzeugen eingesetzt werden und / oder der Schwingungsdämpfung dienen, werden unter Verwendung elastomerer Mischungen, auch als Kautschukmischungen bezeichnet, hergestellt. Diese, für die grundlegenden Eigenschaften solcher Artikel üblicherweise verwendeten elastomeren Mischungen sind hinreichend bekannt. Artikel mit herausragenden elastischen Eigenschaften, wie bspw. Metall-Gummi-Elemente oder Schwingungsdämpfer, enthalten vorzugsweise vulkanisierte Kautschukmischungen, die überwiegend auf Naturkautschuk (NR) und / oder Polyisoprenkautschuk (IR) und / oder Butadienkautschuk (BR) basieren. Artikel mit einer sehr guten Witterungs-, Mineralöl- und Wärmebeständigkeit, wie bspw. Luftfederbälge, enthalten vorzugsweise vulkanisierte Kautschukmischungen, die überwiegend auf Chloroprenkautschuk (CR) basieren. Für den Einsatz bei höheren Temperaturen werden in der Regel Kautschukmischungen auf der Basis von Silikonkautschuk eingesetzt.Articles made of polymeric materials, which are used for the suspension of motor vehicles or rail vehicles, for example, and/or serve to dampen vibrations, are produced using elastomeric mixtures, also referred to as rubber mixtures. These elastomeric compounds, which are commonly used for the basic properties of such articles, are well known. Items with outstanding elastic properties, such as metal-rubber elements or vibration dampers, preferably contain vulcanized rubber mixtures that are predominantly based on natural rubber (NR) and/or polyisoprene rubber (IR) and/or butadiene rubber (BR). Items with very good weather, mineral oil and heat resistance, such as air spring bellows, preferably contain vulcanized rubber mixtures that are predominantly based on chloroprene rubber (CR). For use at higher temperatures, rubber mixtures based on silicone rubber are generally used.

Die mechanische Stabilität des polymeren Werkstoffs wird durch textile Festigkeitsträger erreicht, die sich meist zwischen den einzelnen Kautschukmischungslagen befinden. Für die Belastbarkeit und die Lebensdauer dieser Artikel spielt die Haftung zwischen dem Festigkeitsträger und der Kautschukmischung eine entscheidende Rolle.The mechanical stability of the polymer material is achieved by textile reinforcements, which are usually located between the individual rubber compound layers. The adhesion between the reinforcement and the rubber compound plays a decisive role in the resilience and service life of these items.

Bei hohen Temperaturen zwischen 90 und 130 °C und hohen mechanischen Belastungen, so zum Beispiel besonders in der Rollfalte eines Luftfederbalges, reicht die Haftung zwischen dem Festigkeitsträger und der Silikonkautschukmischung derzeit allerdings nicht aus. Es kommt zu Ablösungen der Silikonkautschukmischung von dem Festigkeitsträger und somit zur Zerstörung des gesamten Artikels.At high temperatures between 90 and 130 °C and high mechanical loads, for example in the rolling folds of an air spring bellows, the adhesion between the reinforcement and the silicone rubber mixture is currently not sufficient. The silicone rubber mixture detaches from the reinforcement and thus destroys the entire article.

Die Haftung zwischen Silikonkautschuk und verschiedenen Substraten bzw Silikatfasergut, insbesondere Glasfasern oder Asbestfasern, wird zum Beispiel in DE 1 210 406 A oder in DE 103 28 843 A1 beschrieben, ohne dass hierbei allerdings Artikel mit elastischen Eigenschaften zur Verwendung bei hohen Temperaturen diskutiert werden. In EP 2 675 947 B1 wird ein Textilgewebe mit einer Lage einer flüssigen Silikonkautschukzusammensetzung zur Herstellung eines AirBags beschichtet.The adhesion between silicone rubber and various substrates or silicate fibers, in particular glass fibers or asbestos fibers, is, for example, DE 1 210 406 A or in DE 103 28 843 A1 without discussing articles with elastic properties for use at high temperatures. In EP 2 675 947 B1 a textile fabric is coated with a layer of a liquid silicone rubber composition to produce an airbag.

Die Aufgabe der Erfindung besteht nun darin, einen Artikel bereitzustellen, der wenigstens eine Silikonkautschukmischung und wenigstens einen Festigkeitsträger enthält, die sich beide in direktem Kontakt zueinander befinden, und der sich durch eine hohe Belastbarkeit und lange Lebensdauer bei hohen Temperaturen und gleichzeitig starker mechanischer Beanspruchung auszeichnet.The object of the invention is to provide an article that contains at least one silicone rubber mixture and at least one reinforcement, both of which are in direct contact with one another, and which is characterized by high resilience and a long service life at high temperatures and, at the same time, high mechanical stress .

Gelöst wird diese Aufgabe dadurch, dass der Artikel mit einem Grundkörper aus einem polymeren Werkstoff mit elastischen Eigenschaften wenigstens eine Silikonkautschukmischung und wenigstens einen Festigkeitsträger aus einem Cord oder einem textilen Flächengebilde besitzt, die sich beide in direktem Kontakt zueinander befinden, wobei der Grundkörper aus mehreren Lagen verschiedener Kautschukmischungen aufgebaut ist und lediglich die Lage des Grundkörpers, die sich in direktem Kontakt zum Festigkeitsträger befindet, aus einer Silikonkautschukmischung besteht, und wobei der Festigkeitsträger vollständig oder teilweise mit wenigstens einer Beschichtung versehen ist, wobei die Beschichtung auf der Basis wenigstens eines Silikonharzlackes ist, welcher zusätzlich 2 bis 20 Gew. -% wenigstens eines Silikonkautschuks enthält.This object is achieved in that the article with a base body made of a polymeric material with elastic properties has at least one silicone rubber mixture and at least one reinforcement made of a cord or a textile fabric, both of which are in direct contact with one another, with the base body consisting of several layers is made up of different rubber mixtures and only the layer of the base body that is in direct contact with the reinforcement consists of a silicone rubber mixture, and the reinforcement is completely or partially provided with at least one coating, the coating being based on at least one silicone resin lacquer, which additionally contains 2 to 20% by weight of at least one silicone rubber.

Überraschenderweise hat sich gezeigt, dass die Kombination von Silikonharzlack und Silikonkautschuk als Beschichtung eine optimierte Haftung zwischen Festigkeitsträger und Silikonkautschuk ergibt, so dass die Lebensdauer derartiger Artikel deutlich erhöht werden kann. Hierdurch wird es ermöglicht, die allgemeinen Vorteile des Silikonkautschuks in der Kautschukmischung des Grundkörpers auch bei dynamischen Anwendungen unter hoher Temperatur zuverlässig zu nutzen.Surprisingly, it has been shown that the combination of silicone resin paint and silicone rubber as a coating results in optimized adhesion between the reinforcement and silicone rubber, so that the service life of such articles can be significantly increased. This makes it possible to reliably use the general advantages of the silicone rubber in the rubber mixture of the base body, even in dynamic applications at high temperatures.

Der Silikonharzlack alleine haftet zwar sehr gut am Festigkeitsträger, ist jedoch nach dem Trocknen und spätestens nach dem Vulkanisationsprozess des Artikels zu spröde. Durch Hinzufügen von Silikonkautschuk zu dem Silikonharzlack wird der Lack dauerelastisch, ohne die Haftung am Festigkeitsträger negativ zu beeinflussen. Die Beschichtung kann derart eingestellt werden, dass das Elastizitätsmodul der Beschichtung größer ist als das Elastizitätsmodul des Festigkeitsträgers und kleiner als das Elastizitätsmodul der Silikonkautschukmischung des Grundkörpers. Somit wird eine Anpassung an beide beteiligten Artikelkomponenten erzielt.Although the silicone resin paint alone adheres very well to the reinforcement, it is too brittle after drying and at the latest after the item has been vulcanized. By adding silicone rubber to the silicone resin paint, the paint becomes permanently elastic without negatively affecting adhesion to the reinforcement. The coating can be adjusted in such a way that the modulus of elasticity of the coating is greater than the modulus of elasticity of the reinforcement and smaller than the modulus of elasticity of the silicone rubber mixture of the base body. In this way, an adaptation to both article components involved is achieved.

Teilweise bedeutet in diesem Zusammenhang, dass lediglich bestimmte, definierte Bereiche bzw. Abschnitte der Artikeloberfläche des Gesamtartikels mit der Beschichtung versehen sind.In this context, partially means that only specific, defined areas or sections of the article surface of the entire article are provided with the coating.

Als Silikonkautschuke für den Grundkörper können alle bekannten Silikonkautschuke verwendet werden. Silikonkautschuke sind in den gummielastischen Zustand überführbare Massen, welche als Grundpolymere Polydiorganosiloxane enthalten, die Vernetzungsreaktionen zugängliche Gruppen aufweisen. Als solche kommen vorwiegend H-Atome, OH-Gruppen und Vinyl-Gruppen in Frage, die sich an den Kettenenden befinden, aber auch in die Kette eingebaut sein können. Es wird zwischen heißvulkanisierenden und kaltvulkanisierenden Silikonkautschuken (high/room temperature vulcanizing = HTV/RTV) unterschieden.All known silicone rubbers can be used as silicone rubbers for the base body. Silicone rubbers are in the gummielasti Compositions which can be converted into a state and which contain polydiorganosiloxanes as base polymers which have groups which are accessible to crosslinking reactions. As such, mainly H atoms, OH groups and vinyl groups come into question, which are located at the chain ends, but can also be built into the chain. A distinction is made between hot vulcanizing and cold vulcanizing silicone rubbers (high/room temperature vulcanizing = HTV/RTV).

Insbesondere finden Silikonkautschuke des Typs MVQ (Methyl-Vinyl-Silikonkautschuke) Verwendung. Diese weisen eine erhöhte Temperaturbeständigkeit bei hohen und tiefen Temperaturen auf, besitzen nahezu gleichbleibende mechanische Eigenschaften über den gesamten Temperaturbereich und zeigen ein inertes Verhalten, weshalb sie für einen schadlosen Kontakt mit Lebensmitteln und medizinischen Produkten geeignet sind. In particular, silicone rubbers of the MVQ type (methyl vinyl silicone rubbers) are used. These have increased temperature resistance at high and low temperatures, have almost constant mechanical properties over the entire temperature range and show inert behavior, which is why they are suitable for harmless contact with food and medical products.

Erfindungsgemäß ist der Grundkörper aus mehreren Lagen verschiedener Kautschukmischungen aufgebaut und lediglich die Lage, die sich in direktem Kontakt zum Festigkeitsträger befindet, aus einer Silikonkautschukmischung besteht.According to the invention, the base body is made up of several layers of different rubber mixtures and only the layer that is in direct contact with the reinforcement consists of a silicone rubber mixture.

Die Silikonkautschukmischung enthält weiterhin die üblichen Mischungsingredienzien. Die üblichen Mischungsingredienzien umfassen wenigstens einen Vernetzer oder ein Vernetzersystem (Vernetzungsmittel und Beschleuniger). Zusätzliche Mischungsingredienzien sind zumeist noch ein Füllstoff und/oder ein Verarbeitungshilfsmittel und/oder ein Weichmacher und/oder ein Alterungsschutzmittel sowie gegebenenfalls weitere Zusatzstoffe (z.B. Farbpigmente, Verstärkungsfasern). Diesbezüglich wird auf den allgemeinen Stand der Kautschukmischungstechnologie verwiesen.The silicone rubber compound also contains the usual compounding ingredients. The usual mixture ingredients include at least one crosslinker or a crosslinker system (crosslinking agent and accelerator). Additional mixing ingredients are usually a filler and/or a processing aid and/or a plasticizer and/or an anti-aging agent and, if appropriate, other additives (e.g. color pigments, reinforcing fibers). In this regard, reference is made to the general state of rubber compound technology.

Der Festigkeitsträger des Artikels ist erfindungsgemäß als Cord oder als textiles Flächengebilde ausgebildet.According to the invention, the reinforcement of the article is designed as a cord or as a textile fabric.

Das textile Flächengebilde kann hierbei bevorzugt als Filz, Vlies, Gewebe, Geflecht, Gewirk, Gestrick oder Gelege ausgebildet sein. Es handelt sich bevorzugt um Webware (engl. woven fabric), bei der die Fläche durch Verkreuzen von zwei Fadensystemen hergestellt wird, oder um eine Maschenware (engl. knitted fabric), bei der eine mittels eines Fadens gebildete Schleife in eine andere Schleife hineingeschlungen wird, und wobei die auf diese Weise entstehenden Maschen unter Verwendung eines oder mehrerer Fäden gebildet werden können.The textile fabric can preferably be designed as a felt, fleece, woven fabric, mesh, knitted fabric, knitted fabric or scrim. It is preferably a woven fabric, in which the surface is produced by crossing two thread systems, or a knitted fabric, in which a loop formed by means of a thread is looped into another loop , and the resulting stitches can be formed using one or more threads.

Als besonders gut geeignet, insbesondere wenn es sich bei dem Artikel um eine Luftfeder handelt, hat sich die Verwendung eines Cordgewebes gezeigt, das aus Schuss- und Kettfäden besteht, wobei nur die Kettfäden tragend sind. Die Schussfäden werden bei der Kalandrierung, beim Vulkanisieren oder im Betrieb gebrochen. Durch die Verwendung von mindestens zwei Gewebelagen ergibt sich der für einen Rollbalg einer Luftfeder erforderliche Kreuzverbund.The use of a cord fabric that consists of weft and warp threads, with only the warp threads being load-bearing, has proven to be particularly well suited, especially when the article is an air spring. The weft threads are broken during calendering, vulcanization or during operation. The use of at least two layers of fabric results in the cross-bonding required for a rolling bellows of an air spring.

Das textile Flächengebilde besteht aus Textilfasern, die gleich oder verschieden voneinander sein können.The textile fabric consists of textile fibers, which can be the same or different from each other.

Als Textilfasern können bevorzugt Naturfasern verwendet werden. Hierbei kann es sich um mineralische Naturfasern, wie bspw. Asbestfasern oder Steinwolle, pflanzliche Naturfasern, wie bspw. aus Baumwolle, Flachs oder Hanf, oder auch um tierische Naturfasern, wie bspw. aus Wolle oder Seide, handeln.Natural fibers can preferably be used as textile fibers. These can be natural mineral fibers such as asbestos fibers or rock wool, natural plant fibers such as cotton, flax or hemp, or natural animal fibers such as wool or silk.

Weiterhin können als Textilfasern bevorzugt Fasern aus natürlichen Polymeren, wie bspw. Regeneratfasern auf Cellulosebasis, wie Viskose, Lyocell oder Gummi, oder auch Fasern aus synthetischen Polymeren, wie bspw. Polyacrylnitril, Polypropylen, Polyester, Polyamid, Polyurethan, Polyphenylensulfid, Polyoxadiazol, Aramid, co-poly para Aramid, Polyimid, Polyetherimid, Polyetheretherketon, Polyethylen-2,6-naphthalat, Polyphenylen, Polyphenylenoxid, Polyphenylensulfid, Polyphenylenether, Polybenzoxazole, eingesetzt werden.Furthermore, fibers made of natural polymers, such as regenerated fibers based on cellulose, such as viscose, lyocell or rubber, or also fibers made of synthetic polymers, such as polyacrylonitrile, polypropylene, polyester, polyamide, polyurethane, polyphenylene sulfide, polyoxadiazole, aramid, co-poly para aramid, polyimide, polyetherimide, polyetheretherketone, polyethylene-2,6-naphthalate, polyphenylene, polyphenylene oxide, polyphenylene sulfide, polyphenylene ether, polybenzoxazole.

Es ist ebenso denkbar, Textilfasern aus anorganischen Stoffen wie Glas, Keramik, Kohlenstoff (Carbon), Metall oder Gestein, wie bspw. Basalt, zu verwenden.It is also conceivable to use textile fibers made from inorganic materials such as glass, ceramics, carbon, metal or stone such as basalt.

Die Textilfasern können alleine oder in Kombination, d.h. als Hybridfaser, eingesetzt werden.The textile fibers can be used alone or in combination, i.e. as hybrid fibers.

Die Beschichtung des Festigkeitsträgers kann einseitig oder beidseitig erfolgen. Zur Optimierung der Haftung ist eine beidseitige Beschichtung zweckdienlich.The reinforcement can be coated on one or both sides. Coating on both sides is useful to optimize adhesion.

Die Beschichtung besteht erfindungsgemäß aus wenigstens einem Silikonharzlack, welche zusätzlich 2 bis 20 Gew.-% wenigstens eines Silikonkautschuks enthält.According to the invention, the coating consists of at least one silicone resin lacquer which additionally contains 2 to 20% by weight of at least one silicone rubber.

Als Silikonharze können alle der fachkundigen Person bekannten Silikonharze verwendet werden. Silikonharze sind mehr oder minder vernetzte Polymethylsiloxane oder Polymethylphenylsiloxane, deren Elastizität und Wärmebeständigkeit mit dem Gehalt an Phenyl-Gruppen steigt. Reine Methyl-Silikonharze sind eher spröde und mäßig wärmebeständig. Die Dauerwärmebeständigkeit ist dabei vergleichsweise hoch, zwischen 180 bis 200 °C, die günstigen dielektrischen Werte sind bis 300 °C weitgehend temperaturunabhängig. Werden die Silikonharze in organischen Lösungsmitteln gelöst, so werden Silikonharzlacke erhalten, die z. T. noch zusätzlich mit organischen Harzen, z. B. Alkydharzen und Polyesterharzen, kombiniert werden können. Als Silikonkombinationsharze werden auch Copolymerisate aus niedermolekularen hydroxyfunktionellen Silikonen mit Polyestern, Alkydharzen und Acrylharzen bezeichnet. Im Rahmen der vorliegenden Erfindung können alle Silikonharzlacke verwendet werden.All silicone resins known to a person skilled in the art can be used as silicone resins. Silicone resins are more or less crosslinked polymethylsiloxanes or polymethylphenylsiloxanes whose elasticity and heat resistance increase with the phenyl group content. Pure methyl silicone resins tend to be brittle and moderately heat resistant. The long-term heat resistance is comparatively high, between 180 and 200 °C, the favorable dielectric values are up to 300 °C independent of temperature. If the silicone resins are dissolved in organic solvents, silicone resin paints are obtained which, for. T. additionally with organic resins, z. B. alkyd resins and polyester resins can be combined. Copolymers of low molecular weight hydroxy-functional silicones with polyesters, alkyd resins and acrylic resins are also referred to as silicone combination resins. All silicone resin paints can be used within the scope of the present invention.

Besonders geeignet sind sogenannte Ofenlacke, wie sie zum Beispiel von der Fa. Weilburger Coatings unter dem Handelsnamen „Senotherm®“ erhältlich sind. Diese sind besonders temperaturstabil und die organischen Komponenten der Ofenlacke zersetzen sich erst bei sehr hoher Temperatur (> 220 bzw. 230 °C).So-called oven paints, such as those available from Weilburger Coatings under the trade name “Senotherm®”, are particularly suitable. These are particularly temperature-stable and the organic components of the oven coatings only decompose at very high temperatures (> 220 or 230 °C).

Dem Silikonharzlack werden 2 bis 20 Gew.-%, bevorzugt 5 bis 10 Gew.-% wenigstens eines Silikonkautschuks hinzugefügt.2 to 20% by weight, preferably 5 to 10% by weight, of at least one silicone rubber are added to the silicone resin lacquer.

Idealerweise handelt es sich dabei um den gleichen Silikonkautschuk, wie er auch für den Grundkörper oder zumindest für den Bereich des Artikels, der sich in direktem Kontakt zum Festigkeitsträger befindet, verwendet wird.Ideally, this is the same silicone rubber that is used for the main body or at least for the area of the article that is in direct contact with the reinforcement.

Der Silikonkautschuk und der mit Silikonkautschuk versehene Silikonlack bilden einen ausgezeichneten Haftverbund. Gleichzeitig haftet der sehr klebrige Lack hervorragend an dem Festigkeitsträger, insbesondere an einem textilen Flächengebilde in Form eines Gewebes, bevorzugt eines Cordgewebes.The silicone rubber and the silicone varnish provided with silicone rubber form an excellent adhesive bond. At the same time, the very sticky lacquer adheres excellently to the reinforcement, in particular to a textile fabric in the form of a fabric, preferably a cord fabric.

Der Festigkeitsträger wird mit der so erhaltenen Masse beschichtet. Dies kann durch Tauchen und / oder Streichen erfolgen. Nach der Trocknung kann der so beschichtete Festigkeitsträger zur Herstellung des Artikels weiterverarbeitet werden.The reinforcement is coated with the mass thus obtained. This can be done by dipping and/or stroking. After drying, the reinforcing element coated in this way can be further processed to produce the article.

Der Artikel ist hierbei bevorzugt eine Luftfeder, insbesondere der Rollbalg einer Luftfeder, ein Antriebsriemen, ein Fördergurt, ein Fahrzeugluftreifen, ein Schlauch, ein Drucktuch, ein beschichtetes Gewebe zur Herstellung von Drucktüchern, Schutzanzügen, Membranen, etc.The article is preferably an air spring, in particular the rolling bellows of an air spring, a drive belt, a conveyor belt, a pneumatic vehicle tire, a hose, a printing blanket, a coated fabric for the production of printing blankets, protective suits, membranes, etc.
