Definitions

  • the invention is based on an elastomer molded part according to the preamble of the main claim.
  • a known elastomer molded part has good strength and elasticity on the one hand due to the base body, and on the other hand it has high gas impermeability. It is disadvantageous, however, that the layer made of gas-impermeable material does not adhere optimally and is damaged by contact with liquids in particular, as a result of which gas impermeability suffers.
  • the elastomer molded part according to the invention with the characterizing features of the main claim has the advantage that the service life and gas impermeability are significantly improved with little additional effort.
  • the measures listed in the subclaims enable further developments of the features specified in the main claim.
  • the drawing shows a section through a membrane elastomer molded part.
  • the elastomer molded part 10 arranged as a partition between a liquid and a gas in a container has a multi-layer structure. It has, for example, two preformed, partially or completely vulcanized base bodies 11, 12 made of a rubber-elastic material of the same or different material base.
  • the base body can, for example, have an approximately hemispherical shape with a radially outwardly directed edge 13 which is fastened to the container (not shown).
  • a binder 14 is applied, for. 3. an adhesive or elastic adhesive.
  • a similar application 15 is carried out on the side of the other part which faces the side of the first base body.
  • a layer 16 in particular thermoplastic film, from one plant fabric with very low gas impermeability. Suitable materials for this are polyvinyl alcohol (PVAL), polyvinylidene chloride (PVDC), polyvinylidene fluoride (PVDF) and compounds made of PVAL with a PVDC coating or films made of other suitable thermoplastics with a PVDC coating.
  • the parts pretreated in this way are expediently firmly connected to one another, the elastic elastomer molded part is then fastened with its edge in the container. It is important that the gas-impermeable material does not come into contact with a liquid.
  • Such an elastomer molded part is particularly suitable as a partition in pressure accumulators used in hydraulic systems, in which it separates a gas space from a liquid space.

Abstract

Le préformé d'élastomère comporte deux corps de base (11, 12) en gomme élastique dont les composants de base sont semblables ou différents, ainsi qu'une couche (16) de matériau imperméable au gaz, par exemple de l'alcool polyvinylique, insérée entre les deux corps. La liaison des deux corps de base (11, 12) avec la couche intermédiaire (16) est réalisée grâce à un liant (14, 15). Le préformé d'élastomère convient particulièrement bien aux appareils sous pression dans lesquels un liquide est séparé d'un gaz.
