Definitions

  • the invention relates to an electrical line with halogen-free, heat-resistant and flame-retardant insulation, which has improved resistance to liquid media and mechanical stress.
  • halogen-free insulation materials e.g. Polyethylene, ethylene-propylene terpolymer, etc. used. It is also known that the solvent resistance and also the short-term temperature resistance of these materials can be improved by crosslinking. As is also known, the flame resistance of halogen-free insulation materials is at least largely achieved by adding metal hydrates (e.g. aluminum oxytrihydrate, magnesium hydroxide).
  • the aim of the present invention is to overcome the disadvantages of the previously known heat-resistant, to fix flame-retardant, halogen-free, insulated cables.
  • a first halogen-free insulation material is additionally protected by a second insulation material made of polyamide, a thermoplastic, halogen-free polyester elastomer, for example "Hytrel 4056" from DuPont, or an aromatic, halogen-free polyether, such as "PEEK” from ICI becomes.
  • the material for the protective layer is chosen more favorably, the abrasion resistance and the lubricity of the electrical line insulated in this way with two layers can be improved.
  • Polyamide 6.6 i.e. Polyhexamethylene adipamide and polyamide 12, i.e. Polylaurin lactam.
  • the first insulation layer is advantageously produced in a thickness of approximately 0.2 to 2 mm, while the outer protective layer can be relatively thin and is generally approximately 0.1 to 0.5 mm.
  • a copper strand made of 50 individual wires with a diameter of 0.25 mm and a total cross section of 2.5 mm 2 and a diameter of 2.1 mm was used in the usual way a first insulation layer made of up to approx. 50 "Radox-125" copolymer filled with aluminum oxytrihydrate ("Radox 125" is the registered trademark for polyolefin copolymers from Huber & Suhner AG), so that the outside diameter of line 3, was 6 mm.
  • the insulation layer was then cross-linked by exposure to high-energy electron beams at a dose of 5 to 20 Mrad.
  • a 0.1 mm thick protective layer made of polyamide 6.6 (eg type "Zytel BK 157", supplier DuPont) was placed on the electrical line thus obtained, so that a double-insulated electrical line with an outer diameter of 3.8 mm was produced has been.
  • the double layer insulated line was stored in ASTM No. 2 mineral oil at a temperature of 100 ° C for 72 hours and in diesel oil at a temperature of 70 ° C for 168 hours. Immediately afterwards, the line was subjected to a winding test around a metal mandrel, the diameter of which corresponds to three times the line diameter, without the samples showing any change.
  • the flame retardancy test according to the publication IEC 332-1 was optimally fulfilled by the double-layer insulated cable.
  • a copper strand made of 50 individual wires of 0.25 mm diameter with a total cross section of 2.5 mm and a diameter of 2.1 mm was made in the usual way with a first insulation layer made of "Radox-125 filled with up to about 50% aluminum oxytrihydrate "Copolymer, so that the outer diameter of the line was 3.2 mm.
  • the insulation layer was then cross-linked by the action of high-energy electron beams with a dose of 5 to 20 Mrad.
  • a 0.3 mm thick protective layer made of polyamide 6.12 (eg type L20H from Ems-Chemie AG) was placed on the electrical line thus obtained, so that a double-layer insulated electrical line with an outer diameter of 3.8 mm was produced .
  • Example 2 After storage in mineral oil and diesel oil, as described in Example 1, the lines according to Example 2 showed no changes.
  • Lines according to Examples 1 and 2 are also resistant to refrigerants (e.g. "Freon” from DuPont).
  • Lines according to Example 2 are resistant to termite damage.
  • a copper strand made of 50 individual wires of 0.25 mm diameter with a total cross section of 2.5 mm 2 and a diameter of 2.1 mm was made in the usual way with a first insulation layer with up to approx. 50% "Radox-125 filled with aluminum oxytrihydrate "Copolymer, so that the outer diameter of the line was 3.2 to 3.4 mm.
  • the double-layer line is water-resistant in accordance with the requirements of the publication ICEA-S-68 and resistant to mineral oil and diesel oil, which - as described in Example 1 - was examined.
  • Example 1 The abrasion test requirements described in Example 1 are also met.
  • the permanent heat resistance of the line is 125 ° C.
  • a copper strand made of 50 individual wires with a diameter of 0.25 mm and a total cross section of 2.5 mm 2 with a diameter of 2.1 mm was coated in the usual way with a first insulation layer made of "Radox- filled with up to 50% aluminum oxytrihydrate. 125 "copolymer, so that the outer diameter of the line was 3.6 mm.
  • a 0.1 mm thick protection was extruded onto the electrical line thus obtained layer made of aromatic polyether (eg type "PEEK” from ICI), so that a double-layer insulated electrical line with an outer diameter of 3.8 mm was produced.
  • the double-layer line is water-resistant in accordance with the requirements of publication ICEA-S-68 and resistant to mineral oil and diesel oil and gasoline (test as described in example 1).
  • Example 1 The abrasion test requirements as described in Example 1 were also met. Likewise those of the flame test according to the publication IEC 332-1.
  • the permanent heat resistance of the line is 12 5 ° C.
