Beschreibung description
Die Erfindung betrifft ein asbestfreies, lamellares Schichtmaterial aus einer vulkanisierbaren Mischung aus Elastomeren, Fasern, Füllstoffen oder dgl.The invention relates to an asbestos-free, lamellar layer material from a vulcanizable mixture of elastomers, fibers, fillers or the like.
Asbesthaltige, lamellare Materialien speziell für den Dichtungsbereich sind beispielsweise aus der DE-AS 21 46 309 bekannt. Bedingt durch den Kristallwasserverlust von Asbest ab 550 0c sind derartige asbesthaltige Materialien nur für Temperaturen bis 6500C begrenzt einsetzbar. Asbestfasern besitzen als Naturfasern aufgrund ihrer chemischen Zusammensetzung, ihrer Struktur und ihren Verunreinigungen Eigenarten, die ihren Anwendungsbereich stark einschränken. Ebenso eingeschränkt ist die wirtschaftliche Verarbeitung der asbesthaltigen, lamellaren Materialien.Asbestos-containing, lamellar materials especially for the sealing area are known from DE-AS 21 46 309, for example. Due to the loss of crystal water of asbestos from 550 0c, such asbestos-containing materials are only suitable for temperatures Limited use up to 6500C. Asbestos fibers are considered natural fibers because of their chemical composition, its structure and its impurities peculiarities, which severely limit their scope. The economic one is just as limited Processing of asbestos-containing, lamellar materials.
Bisher bekannte asbestfreie Materialien weisen den Nachteil auf, daß das Ausgangsmaterial nur auf speziellen Anlagen zu Platten oder Bahnen verarbeitet werden kann.Asbestos-free materials known so far have the disadvantage that the raw material is only processed into sheets or sheets on special systems can be.
Ferner ist nachteilig, daß jeweils nur eine Lage, die entsprechend den Anforderungen an ihre technologischen Eigenschaften abgestimmt ist, gefertigt werden kann.A further disadvantage is that in each case only one position, the corresponding is tailored to the requirements of its technological properties can be.
Auch eine Kombination mehrerer geforderter Eigenschaften ist mit herkömmlichen Verfahren nicht möglich. Eine Verbindung der Lagen untereinander kann nur mit besonderen Hilfsmitteln, beispielsweise über Kleber, erreicht werden.Neben unzureichender technologischer Eigenschaften diese: Platten-oder Bahnmaterials läßt auch die Wirtschaftlichkeit der Herstellung stark zu wünschen übrig. Selbst bei der Herstellung von Einzelschichten nach jeweils getrennten, unterschiedlichen Herstellmethoden werden nicht die Eigenschaften der Platte oder Bahn erreicht, die für das Material gefordert werden. Die heute bekannten asbest- und elastomerhaltigen Dichtungsmaterialien entsprechen nur teilweise den Anfcd0rungen an die Anpassungsfähigkeit an die Dichtflächen, die hohe Querschnittsdichtigkeit, eine hohe Temperatur- und Druckbelastbarkeit, an Schwefel-Chlorid- und Ferritarmut, elektrische Isolation, niedrige Wärmeleitung, chemische Beständigkeit, gezielte Quellbarkeit und dergleichen mehr. Darüber hinaus ist bei dem bekannten Verfahren und den damit herstellbaren Materialien eine Vereinigung geforderter Eigenschaften oder der Kombination einzelner Bereiche und deren wirtschaftliche Verarbeitbarkeit nicht durchführbar. Es sind bislang keine Herstellmöglichkeiten insbesondere für elastomerhaltige Dichtungen bekannt, die für Drücke bis 1000 bar und Temperaturen bis 850 0C geeignet sind.A combination of several required properties is also compatible with conventional ones Procedure not possible. A connection between the layers can only be achieved with special ones Aids such as adhesives can be achieved, as well as inadequate technological ones Properties of this: plate or sheet material also leaves the economy the manufacture left a lot to be desired. Even when producing single layers after each separate, different production method, the properties are not of the plate or sheet that are required for the material. Today known asbestos and elastomer-containing sealing materials only partially correspond the requirements for adaptability to the sealing surfaces, the high cross-sectional impermeability, high temperature and pressure resistance, low in sulfur, chloride and ferrite, electrical insulation, low heat conduction, chemical resistance, targeted swellability and the like. Furthermore is a union in the known process and the materials that can be produced with it Required properties or the combination of individual areas and their economic Processability not feasible. So far there are no manufacturing options known in particular for elastomer-containing seals that are suitable for pressures up to 1000 bar and temperatures up to 850 ° C. are suitable.
Bei Berührungsflächen besteht oft die Forderung, eine Wärmeübertragung zu verhindern. Stoffe, die allein die Eigenschaft niedriger Wärmeleitzahl aufweisen,versagen dabei, wenn es an bestimmten Stellen gleichzeitig zu hohen Pressungen und hohen Temperaturen kommt. Die hierfür erforderliche hohe Verdichtung führt bei den zur Zeit verfügbaren Materialien entweder zu erhöhter Wärmeleitung oder zum Zerstören der beanspruchten Bereiche. Den Anforderungen an gezielte Wärmeleitung oder Wärmeübertragung an den Berührungsflächen des Baukörpers mit dem Verbindungsglied aus Elastomeren, Fasern und Füllstoffen werden bisher bekannte Ausführungen nicht gerecht, wenn gleichzeitig Dichtheit gefordert wird.In the case of contact surfaces, there is often a requirement for heat transfer to prevent. Substances that only have the property of a low coefficient of thermal conductivity fail if there are high pressures and high pressures at certain points at the same time Temperatures is coming. The high compression required for this leads to the Time available materials either to increase heat conduction or to destroy of the stressed areas. The requirements for targeted heat conduction or heat transfer at the contact surfaces of the structure with the connecting element made of elastomers, Fibers and fillers do not do justice to previously known designs if at the same time Tightness is required.
Weiterhin besteht oft die Forderung, daß eine Übertragung von Körperschall und/oder Körperschwingung, beispielsweise im Kraftfahrzeugbau, herabgesetzt oder verhindert werden soll. Mit bekannten Dämpfungsmaterialien wird dies zwar erreicht, eine Kombination mit gleichzeitiger Dichtheit und/oder Wärmeisolation und/oder gerichteter Wärmeleitung ist dagegen nicht möglich. Gibt man nun Stoffe mit Schichtebenenstruktur mit guten Eigenschaften der Schall- oder Schwingungsdämpfung zu Mischungen aus elastomerhaltigen Isolationsstoffen, so ist dann kein Verarbeiten auf herkömmlichen Anlagen möglich. Ebenso ist kein Verarbeiten der bekannten Materialien zu Platten oder Bahnen auf üblichen Verarbeitungsmaschinen möglich, wenn die Mischungen aus elastomerhaltigen Dichtstoffen Zumischungen von Stoffen zur gerichteten Wärmeableitung aufweisen.Furthermore, there is often the requirement that a transmission of structure-borne noise and / or body vibration, for example in motor vehicle construction, reduced or should be prevented. This is achieved with known damping materials, a combination with simultaneous tightness and / or thermal insulation and / or directional On the other hand, heat conduction is not possible. Now you give fabrics with a layer structure with good sound or vibration damping properties to form mixtures of elastomeric materials Insulation materials, processing on conventional systems is then not possible. Likewise, there is no processing of the known materials for plates or webs on conventional processing machines possible if the mixtures are made sealants containing elastomers, admixtures of substances for directed heat dissipation exhibit.
Der Erfindung liegt die Aufgabe zugrunde, ein asbestfreies, lamellares Schichtmaterial zu schaffen, das sich wirtschaftlich herstellen läßt und das für einen großen Temperatur-und Druckbereich einsetzbar ist.The invention is based on the object of an asbestos-free, lamellar To create layer material that can be produced economically and for a large temperature and pressure range can be used.
Die Lösung dieser Aufgabe wird erfindungsgemäß dadurch erreicht, daß der Mischung hydrophobe und/oder hydrophobierte Stoffe mit großer spezifischer Oberfläche zugesetzt sind.This object is achieved according to the invention in that the mixture of hydrophobic and / or hydrophobized substances with a large specific surface are added.
Die spezifische Oberfläche der hydrophoben oder hydrophobierten Stoffe beträgt vorzugsweise mehr als 100 m2/g.The specific surface of the hydrophobic or hydrophobized substances is preferably more than 100 m 2 / g.
Mit dieser Mischung, bestehend aus einer Grundmischung aus Elastomeren, Fasern und Füllstoffen und den hydrophoben oder hydrophobierten Stoffen ist es möglich, ein Schichtmaterial entsprechend den geforderten Gütewerten zu schaffen.With this mixture, consisting of a basic mixture of elastomers, Fibers and fillers and the hydrophobic or hydrophobized substances, it is possible to create a layer material according to the required quality values.
Dieses Material eignet sich hervorragend zum Abdichten von gasförmigen, flüssigen oder festen Stoffen bei Drücken von bis zu 1000 bar und Temperaturen bis 850°C. Es ist weiterhin gleichzeitig sehr gut zum gerichteten Ableiten der Wärme, zum Begrenzen des Wärmedurchgangs und zum Dämmen von Körperschall und Körperschwingungen geeignet.This material is ideal for sealing gaseous, liquid or solid substances at pressures of up to 1000 bar and temperatures of up to 850 ° C. It is also very good for the directional dissipation of heat, to limit the heat transfer and to dampen structure-borne noise and body vibrations suitable.
Als hydrophobe oder hydrophobierte Stoffe werden der Mischung vorzugsweise Organo-Silane, hydrophobierter Ruß, hydrophobierte Kieselsäure oder hydrophobiertes Kieselgur entweder allein oder in Mischungen zugesetzt. Entsprechend den geforderten technischen Bedingungen kann dabei ein unterschiedlicher schichtenmäßiger Aufbau des Materials erfolgen. Die Anordnung der Einzellagen kann in Ausgestaltung der Erfindung verschiedene Zusammensetzungen und in unterschiedlichen Dicken beliebig untereinander vorgesehen werden.The mixture is preferred as hydrophobic or hydrophobicized substances Organo-silanes, hydrophobized carbon black, hydrophobized silica or hydrophobized Diatomaceous earth added either alone or in mixtures. According to the required technical conditions can be a different layer structure of the material. The arrangement of the individual layers can in the embodiment of Invention different compositions and in different thicknesses as desired are provided among each other.
Ferner kann vorgesehen sein, daß metallische oder nichtmetallische Werkstoffe in dem Material eingebettet sind, wobei insbesondere gerasterte oder perforierte Folien, Gewebe, Vliese oder monofile oder gebündelte Drähte verwendet werden können.It can also be provided that metallic or non-metallic Materials are embedded in the material, being in particular rasterized or perforated foils, fabrics, fleeces or monofilaments or bundles Wires can be used.
Das asbestfreie lamellare Material wird vorzugsweise in Platten oder Bahnen ausgebildet. Eine bevorzugte Verwendung des erfindungsgemäßen Materials erfolgt dabei als Formteil für Verbindungsglieder zwischen festen und beweglichen Berührungsflächen von Baukörpern, wobei es insbesondere zum Abdichten von gasförmigen, flüssigen oder festen Stoffen für Drücke bis 1000 bar und Temperaturen bis 8500C und zum Dämmen von Wärme, Körperschall und Körperschwingungen eingesetzt wird.The asbestos-free lamellar material is preferably in sheets or Trained tracks. A preferred use of the material according to the invention takes place as a molded part for connecting links between fixed and movable contact surfaces of structures, in particular for sealing gaseous, liquid or solid materials for pressures up to 1000 bar and temperatures up to 8500C and for insulation heat, structure-borne noise and body vibrations are used.
Ein erfindungsgemäßes Verfahren zur Herstellung des asbestfreien, lamellaren Schichtmaterials -liegt darin, eine Grundmischung aus Elastomeren, Fasern und Füllstoffen, zu mischen dieser Grundmischung einen hydrophoben oder hydrophobierten Stoff mit großer spezifischer Oberfläche zuzusetzen und diese Mischung auf herkömmlichen Anlagen, insbesondere auf einem Kalander zu verarbeiten. Dabei ist es möglich, Zwischenschichten aus asbestfreien, elastomerhaltigen Materialien mit Zugabe derartiger hydrophober oder hydrophobierter Stoffe mit gerichtetem Wärmeableitvermögen an asbestfreie, elastomere Schichten mit Zugaben von hydrophoben oder hydrophobierten Stoffen mit hoher Dichtwirkung anzubinden, wobei zwischen den Schichten ausgezeichnete Hafteigenschaften gegeben sind'auch dann, wenn die Schichten in Arbeitsfolgegängen auf der gleichen maschinellen Einrichtung hergestellt werden. Die gleiche Verarbeitungsmethode ist ohne Einschränkung gewährleistet, wenn Schichten aus asbestfreien, elastomerhaltigen Materialien mit Anteilen hydrophober und/oder hydrophobierter Stoffe mit hoher Dichtwirkung in Verbindung mit Schichten, bei denen der Wärmedurchgang begrenzt ist oder eine Dämmung des Körperschalls oder Körperschwingung besteht, hergestellt werden. Auch ein Verbund von Schichten mit hoher Dichtwirkung, gerichteter Wärmeableitung, begrenztem Wärmedurchgang und hoher Dämm- wirkung gegen Körperschall und Körperschwingung untereinander in beliebiger Anordnung ist mit hoher Haftfestigkeit gegeben, wenn ein entsprechender Anteil hydrophober und/oder hydrophobierter Stoffe mit großer spezifischer Oberfläche vorliegt. Eine derartige Grundmischung aus Elastomeren, Fasern und Füllstoffen in Verbindung mit hydrophoben und/oder hydrophobierten Stoffen kann auf allen bekannten maschinellen Einrichtungen zur Herstellung von Platten oder Bahnen aus mehreren Schichten in allen beispielsweise für Verbindungsglieder von Baukörpern benutzten Dicken in einer sehr wirtschaftlichen Arbeitsweise bei erhöhten technologischen Gütewerten verarbeitet werden. Diese ausgezeichneten Verarbeitungsmöglichkeiten und die sichere Verankerung der asbestfreien, elastomerhaltigen Stoffe mit den hydrophoben und/oder hydrophobierten Stoffe mit großer spezifischer Oberfläche mit ihrem unterschiedlichen Aufbau zur Erreichung hoher Dichtheit für Drücke bis 1000 bar und Temperaturen bis 850 0C gegen flüssige, gasförmige oder feste Medien, zum gerichteten Ableiten von Wärme, zum Begrenzen des Wärmedurchgangs und zum Dämmen von Körperschall und Körperschwingungen ermöglicht es, in die einzelnen Schichten einer derartig hergestellten Platte oder Bahn metallische oder nichtmetallische Werkstoffe in Form von gerasterten oder perforierten Folien, Geweben, Vliesen, monofilen oder gebündelten Drähten oder Fäden einzubetten. Die Bewehrung derartiger Platten oder Bahnen erbringt den bekannten Materialien gegenüber nicht vorauszusehende erhöhte technologische Gütewerte von bislang nicht erreichter Höhe.A method according to the invention for producing the asbestos-free, lamellar layer material - lies in it, a basic mixture of elastomers, fibers and fillers, to mix this basic mixture a hydrophobic or hydrophobized one Add substance with a large specific surface and this mixture on conventional Plants, especially to be processed on a calender. It is possible to use intermediate layers Made of asbestos-free, elastomer-containing materials with the addition of such hydrophobic materials or hydrophobized substances with directed heat dissipation to asbestos-free, elastomeric layers with additions of hydrophobic or hydrophobized substances high sealing effect, with excellent adhesive properties between the layers are also given if the shifts in work sequences are on the same machine device are produced. The same processing method is Guaranteed without restriction if layers made of asbestos-free, elastomer-containing Materials with proportions of hydrophobic and / or hydrophobic substances with a high sealing effect in connection with layers in which the heat transfer is limited or a Attenuation of the structure-borne noise or body vibration exists. Even a composite of layers with a high sealing effect, directed heat dissipation, limited Heat transfer and high insulation effect against structure-borne noise and body vibration with each other in any arrangement is given with high adhesive strength, if a corresponding proportion of hydrophobic and / or hydrophobized substances with a large specific surface is present. Such a basic mixture of elastomers, Fibers and fillers in connection with hydrophobic and / or hydrophobized substances can be used on all known machine equipment for the production of panels or webs of several layers in all for example for connecting links of building structures used thicknesses in a very economical way of working increased technological quality values are processed. These excellent processing options and the secure anchoring of the asbestos-free, elastomer-containing materials with the hydrophobic ones and / or hydrophobized substances with a large specific surface with their different Structure to achieve high tightness for pressures up to 1000 bar and temperatures up to 850 0C against liquid, gaseous or solid media, for directed discharge of Heat, to limit the heat transfer and to dampen structure-borne noise and body vibrations makes it possible in the individual layers of a plate or manufactured in this way Railway metallic or non-metallic materials in the form of gridded or perforated Embed foils, fabrics, fleece, monofilament or bundled wires or threads. The reinforcement of such plates or sheets produces the known materials compared to not foreseeable increased technological quality values of not previously reached height.
Als hydrophobe und hydrophobierte Stoffe mit hoher spezi-2 fischer Oberfläche von mehr als 100 in /g nach BET werden den asbestfreien, elastomerhaltigen Mischungen beispielsweise Organo-Silane, hydrophobierter 2vuß, hydrophobierte Kieselsäure oder hydrophobiertes Kieselgur zugesetzt. Dies kann allein oder in Mischungen geschehen.As hydrophobic and hydrophobic substances with a high speci-2 fischer Surface areas of more than 100 in / g according to BET are asbestos-free, elastomer-containing Mixtures, for example organosilanes, hydrophobized 2vuss, hydrophobized silica or hydrophobized kieselguhr added. This can be done alone or in mixtures.
