Definitions

  • the invention relates to an elastomer mixture, in particular based on EPM or EPDM, to which a conductive component was added, for the purpose of producing a hose for use as a solar collector and heat exchanger.
  • a hose comprising an inner layer made of elastomeric material or plastic and a thermally conductive reinforcement arranged above the inner layer, which is adhesively connected to the inner layer.
  • the reinforcement is covered with an outer layer, which consists of the same material as the inner layer.
  • the reinforcement can also be colored with a special coating, preferably in conjunction with a black coloring.
  • suction and pressure hoses for example pump hoses, hydraulic hoses and chemical safety hoses, are necessarily provided with at least one reinforcement insert, hoses for use as a solar collector and heat exchanger can also be free of reinforcement supports.
  • a further disadvantage is that, with respect to the tube wall thickness, the reinforcing members comprise only a limited spatial portion. This has to As a result, the increased thermal conductivity associated with this measure does not extend to the entire hose wall.
  • the task is to provide an elastomer mixture for a generic hose with or without reinforcement, which can be extruded with an improved thermal conductivity of ⁇ > 1 W / m ° K while maintaining the rubber-elastic properties, and with fulfillment the necessary spray smoothness, which is important for good thermal conductivity (heat transfer).
  • Rubber component 50 - 100 (60 - 80) thermally conductive component 50 - 150 (70 - 120)
  • Activator 1 - 5 (1 - 4) EPM or EPDM in particular are used as the rubber component, these abbreviations having the following meanings:
  • the carbon black is, for example, an amorphous carbon black.
  • Di (tert-butyl-peroxyisopropyl) benzene for example, is used as the peroxidic crosslinking agent.
  • the activator is, for example, triallyl cyanurate (TAC).
