Elastomerformteil
Stand der Technik Molded elastomer part
State of the art

Die Erfindung geht aus von einem Elastomerformteil nach der Gattung des Ha-uptanspruchs. Ein derartiges bekanntes Elastomerformteil besitzt einerseits durch den Grundkörper gute Festigkeit und Elastizität, andererseits weist er eine hohe Gasundurchlässigkeit auf. Nachteilig ist jedoch, daß die Schicht aus gasundurchlässigem Werkstoff nicht optimal haftet und durch Berührung vor allem mit Flüssigkeiten beschädigt wird, wodurch die Gasundurchlässigkeit leidet.The invention is based on an elastomer molding of the genus of the main claim. Such a well-known one Elastomer molding has on the one hand good strength and elasticity due to the base body, on the other hand it has he has a high gas impermeability. However, it is disadvantageous that the layer of gas-impermeable material is not adheres optimally and is damaged by contact with liquids in particular, which makes it impermeable to gas suffers.

Vorteile der ErfindungAdvantages of the invention

Das erfindungsgemäße Elastomerformteil mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß die Lebensdauer und Gasundurchlässigkeit bei nur geringfügigem Mehraufwand wesentlich verbessert sind.The elastomer molding according to the invention with the characterizing Features of the main claim has the advantage that the service life and gas impermeability with only a little extra effort are significantly improved.

Zeichnungdrawing

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Die Zeichnung zeigt einen Schnitt durch ein membranariges Elastomerformteil.An embodiment of the invention is shown in the drawing and in the following description in more detail explained. The drawing shows a section through a membrane-like elastomer molding.

Beschreibung des ErfindungsbeispielsDescription of the example of the invention

Das al" Trennwand zwischen einer Flüssigkeit und einem Gas in einem Behälter angeordnete Elastomerformteil 10 ist mehrschichtig aufgebaut. Es weist beispielsweise zwei vorgeformte, teil- oder vollständig ausvulkanisierte, ineinander passende Grundkörper 11, 12 aus einem gummielastischen Werkstoff gleicher oder unterschiedlicher Stoffbasis auf. Die Grundkörper können beispielsweise etwa halbkugelige Form haben mit einem radial auswärts gerichteten Rand 13, der am nicht dargestellten 3ehälter befestigt ist.The al "dividing wall between a liquid and a gas arranged in a container elastomer molding 10 is built up in several layers. It has, for example, two preformed, partially or fully vulcanized, Matching base bodies 11, 12 made of a rubber-elastic material of the same or different types Based on fabric. The base body can, for example, have an approximately hemispherical shape with a radially outward direction directed edge 13, which is attached to the 3ehälters, not shown.

An derjenigen Seite des einen Grundkörpers 11, welcher der Seite des anderen 12 zugewandt ist, ist ein Bindemittel \k aufgetragen, z. B. ein Haftvermittler oder elastischer Klebstoff. Sine ebensolche Auftragung 15 erfolgt auf der Seite des anderen Teils, die der Seite des ersten Grundkorpers zugewandt ist. Zwischen den beiden einander zugewandten und mit Bindemitteln versehenen Hälften der Grundkorper befindet sich eine Schicht 16, insbesondere thermoplastische Folie, aus einem Werk-On that side of a base body 11 which faces the side of the other 12, a binder \ k is applied, z. B. an adhesion promoter or elastic adhesive. The same application 15 takes place on the side of the other part which faces the side of the first base body. Between the two halves of the base body that face one another and are provided with binding agents, there is a layer 16, in particular a thermoplastic film, made of a material

stoff mit sehr geringer Gasundurchlässigkeit. Als hierfür geeignete Werkstoffe erveisen sich Polyvinylalkohol (PVAL), Polyvinylidenchlorid (PVDC), Polyvinylidenfluorid (PVDP) und VerbunTolien aus PVAL mit PVDC-Beschichtung bzw.
Folien aus anderen geeigneten Thermoplasten mit PVDC-Beschichtung .fabric with very low gas impermeability. Suitable materials for this have been found to be polyvinyl alcohol (PVAL), polyvinylidene chloride (PVDC), polyvinylidene fluoride (PVDP) and composite films made from PVAL with a PVDC coating or
Films made from other suitable thermoplastics with a PVDC coating.

Es ist jedoch ebenso möglich, das Bindemittel auf den Oberflächen der Schicht 16 aufzutragen.However, it is also possible to apply the binder to the surfaces of the layer 16.

Die so vorbehandelten Teile werden auf zweckmäßige Weise fest miteinander verbunden, das elastische Elastomerformteil sodann mit seinem Rand im Behälter befestigt. Wichtig ist hierbei, daß der gasundurchlässige Werkstoff nicht mit einer Flüssigkeit in Berührung kommt.The parts pretreated in this way are firmly connected to one another in an expedient manner, the elastic elastomer molding then attached with its edge in the container. It is important here that the gas-impermeable material does not come into contact with a liquid.

Besonders geeignet ist ein derartiges Elastomerformteil aio Trennwand in in Hydroanlagen verwendeten Druckspeichern, in denen sie einen Gas- von einem Flüssigkeitsraum trennt.Such an elastomer molding is particularly suitable aio partition wall in pressure accumulators used in hydraulic systems, in which it separates a gas from a liquid space.
