Verfahren zur Erhöhung der Leitfähigkeit plastischer Massen.
Den Gegenstand der Erfindung bildet ein Verfahren zur Erhöhung der Leitfähigkeit plastischer Massen, wie sie beispielsweise zur Erzeugung von Dynamobürsten verwendet werden.
Der Erfindung gemäss wird einer konzentrierten Metallsalzlösung eine Seifenlösung zugesetzt, wodurch sich eine Metallseife in Form eines Niederschlages bildet. Dieser Niederschlag wird dem zur Herstellung des elektrischen Leiters bestimmten Material, einer aus Graphit, Kohle, Gummi, Papier u. dgl. bestehenden plastischen Masse in möglichst hohem Prozentsatz beigemengt und mit ihm innig gemischt. Das derart behandelte Material wird hierauf in bekannter Weise gepresst und gebrannt. Das Brennen, welches bei einer Temperatur von höchstens 10000 C erfolgen soll, bewirkt, dass sich das Metall der in der Masse befindlichen, fein verteilten Metallseife mit dieser zu einem homogenen Körper verbindet, welcher eine hohe elektrische Leitfähigkeit besitzt.
Es werden beispielsweise 19 bis 20 Gewichtsteile Kupfervitriol in 100 Gewichtsteilen Wasser gelöst. Dieser Lösung wird eine auf warmem Wege separat hergestellte, möglichst konzentrierte Seifenlösung zugesetzt. Der sich sofort bildende Niederschlag, welcher aus Kupferseife besteht, wird abfiltriert, trocknen gelassen und hierauf mit der doppelten Gewichtsmenge einer unabhängig von dem vorerwähnten Verfahren aus Graphit und Kohle hergestellten Masse plastischen Masse vermengt. Nunmehr wird diese Masse in Formen gepresst und bei einer

Process for increasing the conductivity of plastic masses.
The subject matter of the invention is a method for increasing the conductivity of plastic masses, such as those used, for example, to produce dynamo brushes.
According to the invention, a soap solution is added to a concentrated metal salt solution, whereby a metal soap is formed in the form of a precipitate. This precipitate is the material intended for the production of the electrical conductor, one of graphite, carbon, rubber, paper and the like. Like. Existing plastic mass added in the highest possible percentage and intimately mixed with it. The material treated in this way is then pressed and fired in a known manner. The firing, which should take place at a temperature of no more than 10,000 C, has the effect that the metal of the finely divided metal soap in the mass combines with it to form a homogeneous body, which has a high electrical conductivity.
For example, 19 to 20 parts by weight of vitriol are dissolved in 100 parts by weight of water. A soapy solution that is as concentrated as possible is added to this solution, which has been separately prepared by warming. The precipitate which forms immediately, which consists of copper soap, is filtered off, left to dry and then mixed with twice the amount by weight of a mass of plastic mass produced independently of the above-mentioned process from graphite and carbon. Now this mass is pressed into molds and a
