Definitions

  • the present invention relates to a multilayer structure for protecting a tube, pipe or the like having a metal inner layer, the surface is more specifically based on zinc.
  • This multilayer structure is more particularly intended to be implemented for a tube, pipe or the like but may be ideal for all types of metal supports.
  • the invention also relates to a use of a thermoplastic composition as a binder between a polyolefin and a metal layer, preferably comprising at least 80% zinc, characterized in that the binder consists of the intermediate layer as defined herein. -above.
  • the alkyl (meth) acrylate is chosen from methyl (meth) acrylate, ethyl acrylate, n-butyl acrylate, isobutyl acrylate and 2-ethylhexyl acrylate.
  • the outer layer will preferably be a polyethylene.
  • polyethylenes mention may be made of:
  • nucleating agents examples include aluminum p-tert-butylbenzoate, dibenzylidene sorbitol and aluminum hydroxy-di-p-t-butylbenzoate.
  • the intermediate layer comprising a copolymer of ethylene and at least one unsaturated acid (or acid) carboxylic anhydride may be prepared in a first step by introducing or mixing the one or more constituents by conventional means of thermoplastics, for example extrusion or kneading. It is possible to use internal blender or rotor mixers, an external mixer, a co-kneader, single-screw extruders, co-rotating twin-screw or counter-rotating twin-screw extruders.
  • the intermediate layer is produced at a temperature greater than or equal to the temperature of melting the constituents, for example at a temperature in the range of 100 to 260 ° C.
  • a second step techniques known to those skilled in the art can be used to manufacture the tubes according to the invention.
  • coextrusion techniques can be used.
  • the ductile iron tube is coated with a zinc-based layer, it is possible, for example, to use this preferred method of manufacturing the tube:
