Definitions

  • the present invention relates to an improved method for producing insulated winding wires by extrusion of thermoplastics.
  • Enamel-insulated winding wires so-called “enamelled wires” are precisely characterized in the German standard DIN 46435 from April 1977. They are used on a large scale in electrical engineering, transformer construction and electronics.
  • the conductor metal preferably copper or aluminum, is insulated with a thin, but mechanically and thermally extremely resistant synthetic resin lacquer layer.
  • Such enamelled wires are produced on wire enamelling machines by repeatedly applying an enamelled wire enamel to the metal wire.
  • wire enamel dispersions and aqueous solutions of wire enamel resins as well as resin melts are already used for wire enamelling.
  • thermoplastics for thick-walled sheathing of electrical conductor bundles and for the production of conductor wires has long been known from the cable industry.
  • thermoplastic polycondensates with crystallite melting points above 170 ° C., preferably above 250 ° C., are used as thermoplastics for the extrusion coating of winding wires.
  • polymers with chain sulfur atoms e.g. Called polyphenylene sulfide.
  • the examples describe the extrusion conditions for polyethylene terephthalate, 6,6-polyamide and polyphenylene sulfide and the properties of the winding wires obtained therewith.
  • the invention thus relates to a process for the production of so-called enamel-insulated winding wires by extrusion of partially crystalline thermoplastic polycondensates with crystallite melting points above 170 ° C, preferably above 250 ° C, characterized in that aromatic polyether ketones with recurring units of the formula where Ar is aromatic radicals, which may be the same or different, in particular benzene, naphthalene or diphenyl radicals, and where n is an integer from 50 to 200, are used.
  • Winding wires have a softening temperature of well over 300 ° C and a surface hardness of 2 - 3 H, which is normally only achieved with winding wires with thermoset coatings.
  • thermoplastics In comparison to the values for the other thermoplastics, the thermal shock value of the winding wires insulated with polyether ketone coatings has surprisingly been greatly improved.
  • Coating material Semi-crystalline aromatic polyetherketone of the summary formula
