Definitions

  • the present invention relates to a multilayer fluid line and a fluid line system for the sanitary and heating sector.
  • DE 42 38 696 a two-layer fluid line for liquid fuels, the outer layer comprising a thermoplastic material and preferably additionally containing a radiation-crosslinkable plastic.
  • the thermoplastic material of the outer layer can be an elastomer, in particular a polyamide elastomer, a polyester elastomer or a polyolefin elastomer.
  • the inner layer preferably contains ETFE or PVDF.
  • DE 41 32 984 deals with plastic tubes for the guidance of gaseous media and fluids, such as drinking water or waste water.
  • the pipes proposed by DE 41 32 984 consist of a core pipe made of polyethylene, on which a jacket made of polyvinylidene fluoride is arranged.
  • a protective layer made of polyethylene is used to protect the thin jacket made of PVDF.
  • the core tube can have additional protection in the form of an aluminum jacket.
  • DE 197 07 827 discloses a composite pipe which contains an inner layer made of cross-linked polyethylene, an intermediate layer made of aluminum and an outer layer made of polyethylene.
  • PE polyethylene
  • ETFE ethylene-tetrafluoroethylene copolymer
  • PVDF polyvinylidene fluoride
  • PVC polyvinyl chloride
  • PEX cross-linked polyethylene
  • the fluid line according to the invention comprises at least an inner layer, an intermediate layer and an outer layer, the inner layer consisting of a fluoropolymer or a subsequently fluorinated polymer, the intermediate layer consisting of a metal and the outer layer consisting of a thermoplastic.
  • Such a fluid line has a very favorable combination of properties: the inner layer made of a fluoropolymer or a subsequently fluorinated polymer has a very high chemical resistance, the intermediate layer formed from a metal gives shape stability and represents an effective diffusion barrier and the outer layer from one Thermoplastic acts as a protective layer against damage and at the same time prevents the ingress of contaminants.
  • the inner layer of the fluid line consists of a fluoropolymer, namely of a PVDF material.
  • the plastic PVDF has very good properties with regard to the parameters of pressure resistance, pressure shock resistance, long-term stability, temperature resistance and temperature shock resistance and can also be shaped well.
  • PVDF fulfills all hygienic requirements that are set out in the drinking water ordinance. Fluid lines with an inner layer made of PVDF can therefore be used advantageously for hot and cold water supply. Even very small thicknesses of the PVDF layer cause an absolute diffusion barrier for gases and fluids. The smallest possible thickness of the PVDF layer seems desirable in order to enable the least possible consumption of this cost-intensive material and to keep the weight of the fluid line as low as possible.
  • the inner layer consists of a subsequently fluorinated polymer.
  • a large number of processes for fluorinating polymer materials are known from the prior art, all of which can be used in the context of the present invention.
  • a method for producing plastic profiles with a fluorinated layer according to EP-A-0 267 441 may be mentioned here by way of example. With the aid of this method, subsequent fluorination of the inner layer of the fluid line according to the invention can be carried out without any problems.
  • subsequently fluorinated polymers also excellently fulfill the required properties.
  • subsequently fluorinated polymers have good pressure resistance, pressure shock resistance, long-term stability, temperature resistance and temperature shock resistance and can also be shaped well.
  • fluorinated thermoplastic polymers e.g. Polyethylene, polyvinyl chloride, polyamides, PEX, PVDF, polystyrene, polymethacrylic acid esters, polytetrafluoroethylene, polyvinyl acetate, cellulose acetate or linear polyurethanes.
  • the metallic intermediate layer consists of aluminum or stainless steel.
  • the material aluminum has a high flexural strength, is dimensionally stable, compressible and also represents an effective diffusion barrier. Aluminum therefore fulfills the properties advantageous for fluid lines particularly well.
  • thermoplastic material of the outer layer can e.g. are polyethylene, polyvinyl chloride, polyamides, PEX, PVDF, polystyrene, polymethacrylic acid esters, polytetrafluoroethylene, polyvinyl acetate, cellulose acetate or linear polyurethanes.
  • the outer layer of the fluid line consists of polyethylene or PEX.
  • Polyethylene has a number of advantages such as low weight, very good resistance to aggressive soils and good weldability using all currently known methods. When laying the fluid lines in floors, it is also advantageous that polyethylene is insensitive to frost and resistant to microorganisms and has a high resistance to stress cracking. Polyethylene is also an inexpensive material.
  • the present invention further relates to a fluid line system which comprises at least one of the fluid lines described above and at least one connecting part, wherein at least the inside of the connecting part consists of PVDF.
  • the fluid line system consists exclusively of the fluid lines described above and of connecting parts, the inside of which is made of PVDF.
  • This is a line system for e.g. Drinking water in which all parts in contact with the drinking water are made of PVDF plastic.
  • the fluid line system consists of finally from the fluid lines described above and from connecting parts which are made entirely of PVDF.
  • connecting parts which are made entirely of PVDF.

Abstract

La présente invention concerne une conduite pour liquides destinée au domaine sanitaire et de chauffage. Cette conduite comprend une couche interne, une couche intermédiaire et une couche externe. La couche interne est constituée d'un fluoropolymère ou d'un polymère ultérieurement fluoré, la couche intermédiaire est constituée d'un métal et la couche externe est constituée d'une matière thermoplastique.
