Abstract

Al wire for electrical and mechanical purposes is protected against oxidation and corrosion by a plastic casing which is glued on by an adhesive layer consisting of a polybutene or polybutylene composition, pref. bitumen. The plastic casing consists pref of a thermo-adhesive copolymer, and may be applied by extrusion or wound around the wire as a tape.

Description

  

  
 



   Gegenstand der Erfindung ist ein Metalldraht mit Korrosionsschutz für elektrische, mechanische oder andere Zwecke.



   Derartige korrosionsgeschützte Metalldrähte sind bekannt. Sie bestehen beispielsweise aus Kupfer oder Eisen und sind beispielsweise verzinkt oder mit Lack   undloder    einem anderen Kunststoff ummantelt.



   Eine solche Ummantelung reicht aber bei Aluminiumdrähten nicht aus. Hier haftet eine solche Umhüllung nicht ausreichend fest genug. Wasser oder Feuchtigkeit dringen unter die Umhüllung. Es ergeben sich die bekannten Oxydationsreaktionen und die daraus resultierenden Material- und Leitfähigkeitsschäden. Diese Erkenntnis steht einer weiteren Verbreitung von Aluminiumdrähten hindernd entgegen.



   Aufgabe war somit, einen Metalldraht zu schaffen, der, aus Aluminium bestehend, die geschilderten Nachteile nicht besitzt.



   Es wurde nun gefunden, dass man einen solchen Metalldraht mit Korrosionsschutz schaffen kann, wenn auf einem Aluminiumdraht als Korrosionsschutz der Kunststoffmantel aufgeklebt ist.



   Dabei kann die Klebeschicht aus Polybuten oder aus Polyisobutylen, gegebenenfalls unter Zusatz von Harzen, Wachsen, Füllstoffen, beziehungsweise aus Bitumen bestehen.



   Weiterhin kann der Kunststoffmantel selbst aus einem in der Wärme verklebenden Copolymer bestehen. Die Ummantelung kann aus einem auf den Aluminiumdraht extrudierten Kunststoff, oder aus einem aufgewickelten Kunststoffband bestehen.



   Die Figur zeigt im Querschnitt ein Ausführungsbeispiel des korrosionsgeschützten Drahtes. Es bedeuten:
1 den Aluminiumdraht,
2   2   die Klebeschicht,
3 den Kunststoffmantel.



   Es wird durch die erreichte vollkommene Haftung des Kunststoffmantels auf der Metalloberfläche durch die vermittelnde Klebeschicht ein optimaler Korrosionsschutz erreicht, wodurch den Aluminiumdrähten ganz neue Verwendungsgebiete erschlossen werden. 



  
 



   The invention relates to a metal wire with corrosion protection for electrical, mechanical or other purposes.



   Such corrosion-protected metal wires are known. They consist, for example, of copper or iron and are for example galvanized or coated with paint and / or another plastic.



   However, such a sheathing is not sufficient for aluminum wires. Such a covering does not adhere sufficiently firmly here. Water or moisture penetrate under the cover. The known oxidation reactions and the resulting material and conductivity damage result. This knowledge prevents the further spread of aluminum wires.



   The task was therefore to create a metal wire which, made of aluminum, does not have the disadvantages described.



   It has now been found that such a metal wire with corrosion protection can be created if the plastic jacket is glued to an aluminum wire as corrosion protection.



   The adhesive layer can consist of polybutene or polyisobutylene, optionally with the addition of resins, waxes, fillers, or bitumen.



   Furthermore, the plastic jacket itself can consist of a copolymer that adheres when exposed to heat. The sheathing can consist of a plastic extruded onto the aluminum wire, or a wound plastic tape.



   The figure shows in cross section an embodiment of the corrosion-protected wire. It means:
1 the aluminum wire,
2 2 the adhesive layer,
3 the plastic jacket.



   The perfect adhesion of the plastic jacket to the metal surface is achieved through the mediating adhesive layer, which means that completely new areas of application are opened up for the aluminum wires.
