Description
Isolation elektrischer Leiter, Kabel, Maschinen und Apparate od. dgl. aus polyacrylhaltigen Stoffen I:s sind elektrische Isolationen aus polyacrylhaltigen Stoffen bekannt, die eine sehr gute Witterungs- und Wärmebeständigkeit sowie gute dielektrische Eigenschaften aufweisen. Diese Stoffe haben jedoch den Nachteil, daß sie bei hohen "Temperaturen, z. B. 1x-_i Kurzschluß, monomeres Acrvlnitril oder andere Spaltprodukte ergeben, die eine starke Giftigkeit besitzen.Isolation of electrical conductors, cables, machines and apparatus or the like. Made from materials containing polyacrylics I: s are electrical insulation made from materials containing polyacrylics Known substances that have a very good weather and heat resistance as well as good have dielectric properties. However, these substances have the disadvantage that they at high "temperatures, e.g. 1x-_i short circuit, monomeric acrylonitrile or result in other fission products which are highly toxic.
Die vorliegende Erfindung hat sich die Aufgabe gestellt, die Abspaltung derartiger giftiger Stoffe zu vermeiden.The present invention has set itself the task of splitting off to avoid such toxic substances.
Gemäß der Erfindung wird die polyacrylhaltige Isolation mit Stoffen versehen, die bei der ZersetZungstemperatur des Polyacrylnitrils flüssige oder gasförmige Stoffe abspalten, welche mit dem sich bildenden monomeren Acrylnitril und anderen Spaltprodukten reagieren und diese unschädlich machen. Es können beispielsweise solche Stoffe verwendet werden, welche Aldehyd, Schwefel, Ammoniak und ungesättigte Kohlenwasserstoffe abspalten. Ausführungsbeispiel für Abspalten von Aldehyd ist die Mitverwendung von Aldehydacetaten, wie sie als Rdhstoff für Drahtlacke verarbeitet werden.According to the invention, the polyacrylic insulation is made with fabrics provided that are liquid or gaseous at the decomposition temperature of the polyacrylonitrile Eliminate substances which with the forming monomeric acrylonitrile and others React fission products and render them harmless. For example such substances are used, which aldehyde, sulfur, ammonia and unsaturated Split off hydrocarbons. Embodiment for splitting off aldehyde is the use of aldehyde acetates, as processed as a raw material for wire enamels will.
Diese Stoffe können in Form eines Lackes, einer Durchtränkung oder Imprägnierung bzw. in Form einer Umspinnung oder mittels Sicherungspatronen der polyacryfha.ltigen Isolation beigefügt werden.These substances can be in the form of a varnish, an impregnation or Impregnation or in the form of a wrapping or by means of fuse cartridges polyacrylic insulation can be added.
