Definitions

  • the invention relates to a hose comprising a core and cover with embedded reinforcement, in the form of a single or multi-layer reinforcement structure, the core and cover each consisting of a thermoplastic elastomer.
  • hose structure there is a comprehensive state of the art, which also describes a large number of reinforcement variants, reference being made, for example, to the following publications: DE 33 32 550 C2, EP 0 149 805 B1, EP 0 567 115 B1 and EP 0 848 794 B1.
  • the reinforcement consists of a textile and / or metallic material and depends on the intended use.
  • hoses there are, for example: water hoses, compressed air hoses, oil and petrol hoses, chemical hoses, steam hoses and hydraulic hoses.
  • hoses are made from various materials, such as rubber, plastics (PVC) and rubber-plastic compounds.
  • the generic hose is made of a thermoplastic elastomer (short name TPE).
  • TPE-S thermoplastic elastomers based on styrene
  • TPE-O uncrosslinked or partially crosslinked thermoplastic elastomers based on olefin
  • TPE-V fully crosslinked thermoplastic elastomers based on olefin
  • the hose according to the invention is characterized in that an adhesion-promoting intermediate layer is incorporated, which can be welded to the core and / or ceiling material and thus forms a connection to the reinforcement. The welding takes place during the manufacturing process.
  • the adhesion-promoting intermediate layer is extruded directly onto the core, the strength member then being placed on the intermediate layer.
  • the adhesion-promoting intermediate layer is extruded directly onto the reinforcement, whereby the ceiling is then worked up.
  • the adhesion-promoting intermediate layer is applied to the soul and to the ceiling, so that the reinforcement is completely integrated into the intermediate layer.
  • This variant is particularly advantageous, especially when there are no more thread gaps.
  • the adhesion-promoting intermediate layer is applied between the individual strength members, the above-mentioned variants also being used.
  • the adhesion-promoting intermediate layer has a minimum melting point of 75 ° C and a maximum melting point of 170 ° C.
  • the advantageous materials in relation to the adhesion-promoting intermediate layer are: An olefinic plastic is used, especially based on polyethylene or polypropylene. The reinforcement is twisted around with the olefinic plastic or the olefinic plastic is applied directly to the reinforcement.
  • the adhesion-promoting intermediate layer consists of a TPE (TPE-S, TPE-O, TPE-V) and a hydrocarbon resin, in particular an aromatic hydrocarbon resin, and, if appropriate, from further additives.
  • the hydrocarbon resin content is 2 to 50% by weight, in particular 5 to 30% by weight.
  • the adhesion-promoting intermediate layer is an acrylate copolymer, in particular an ethylene-acrylate copolymer.
  • acrylate copolymer in particular an ethylene-acrylate copolymer.
  • EMA ethylene methyl acrylate
  • ESA ethylene ethyl acrylate
  • EBA ethylene butyl acrylate
  • a hydrocarbon resin in particular again an aromatic hydrocarbon resin, and optionally further additives are / are admixed to the acrylate copolymer.
  • the hydrocarbon resin content here is 2 to 50% by weight, in particular 5 to 30% by weight.
  • a further component in the form of a functionalized polymer is preferably added to the adhesion-promoting intermediate layer.
  • This additional component is a maleic anhydride grafted polyethylene or a similarly grafted polypropylene or an acrylate copolymer functionalized with polar CO groups or epoxy groups.
  • the proportion of the functionalized polymer is 0.5 to 20% by weight, in particular 2 to 10% by weight.
  • the adhesion-promoting intermediate layer is a hydrocarbon resin, in particular an aromatic hydrocarbon resin.
  • the hydrocarbon resin has a softening point of 75 ° C to 145 ° C, in particular 100 ° C to 145 ° C.
  • the above data in% by weight relate to the total mass of the adhesion-promoting intermediate layer.

Abstract

L'invention concerne un flexible comprenant une couche intérieure et une couche extérieure avec un support de résistance incorporé, notamment sous forme de structure de support de résistance à une ou à plusieurs couches. La couche intérieure et la couche extérieure comprennent dans chaque cas un élastomère thermoplastique. Selon l'invention, il est prévu en outre une couche intermédiaire de pontage, incorporée, qui peut être soudée au matériau de la couche intérieure et/ou de la couche extérieure, et se fixe ainsi que support de résistance. Des variantes de conception appropriées sont prévues pour la couche intermédiaire de pontage.
