Description
Verfahren zum Herstellen von Kautschuküberzügen auf Metallteilen, insbesondere von elektrischen Leitungen, durch elektrisches Niederschlagen aus Kautschukmilch Es ist bereits bekannt, Kautschuküberzüge auf Metallteilen dadurch herzustellen, daß man das Gummi aus Kautschukmilch durch elektrischen Strom auf den Metallteilen niederschlägt. Auf bestimmten Metallen, z.B. Kupfer und Zinn, lassen sich bekanntlich nach diesem %Terfahren mir sehr dünne Schichten Kautschuk niederschlagen, während auf andere Metalle, beispielsweise Zink und Aluminium, derartige Schichten in beliebiger Stiirke aufgebracht «-erden können. L n i auch auf solche Metalle, die das -Niederschlagen nur sehr dünner Schichten zulassen, stärkere Schichten aufbringen zti können, ist es erforderlich, diese Metalle zunächst mit einem L'berzug aus solchen Metallen zii versehen, die beliebige Schichtdicken aufnehmen, z. B. finit Zink oder Aluminium, und auf diesen dann die Kautschukmilch elektrisch niederzuschlagen. Bei den Metallen mit guter Aufnahmefähigkeit des Niederschlages hängt nun die aufzubringende Schichtdicke von der Zeit des Niederschlagens in der Kautschukinilch ab. und es ist deshalb erforderlich, die Herstellung genau zu überwachen, um eine angestrebte Schichtdicke Kautschuk zu erzielen.Process for the production of rubber coatings on metal parts, in particular of electrical lines, by electrically depositing rubber milk It is already known to produce rubber coatings on metal parts by that the rubber can be made from rubber milk by means of an electric current on the metal parts precipitates. It is well known that certain metals, e.g. copper and tin, can be used after this time I deposit very thin layers of rubber while on other metals, for example zinc and aluminum, such layers in any desired Strength applied "-be able to earth. L n i also apply to metals that precipitate Only allow very thin layers to be able to apply thicker layers it is necessary to first coat these metals with a coating of such metals zii provided that accommodate any layer thickness, z. B. finite zinc or aluminum, and then to electrically deposit the rubber milk on these. With the metals If the precipitate has a good absorption capacity, the thickness of the layer to be applied depends from the time of precipitation in the rubber milk. and it is therefore necessary closely monitor the production process in order to achieve a desired layer thickness of rubber to achieve.
Gemäß der Erfindung wird nun jede ("berwachting beim Aufbringen der Kautschukmilch auf Metallen, die mit Metallüberzügen guter Aufnahmefähigkeit versehen sind, dadurch überflüssig gemacht, daß man die Metallschicht guter Aufnahmefähigkeit in einer Stärke aufbringt, durch «-elche die Stärke der niedergeschlagenen Kautschulcschicht bestimmt ist. Sobald diese Metallschicht guter Aufnahmefähigkeit durch die Lösung verbraucht ist, hört der Niederschlag aus der Dispersion selbsttätig auf, und es ist dann nicht möglich, die Kautschulzschicht trotz willkürlich veriäiigerter Einwirkungsdauer zu verstärken. Wenn man in dieser Weise verfährt, ist es demnach nicht erforderlich, während des Niederschlagens aus der Kautschukmilch die Herstellung zu überwachen. Man erzielt außerdem den Vorteil, daß sich beim Arbeiten nach diesem Verfahren ein sehr gleichmäßiges Erzeugnis ergibt.According to the invention, each ("monitored when applying the Rubber milk on metals, provided with metal coatings with good absorption are made superfluous by the fact that the metal layer has good absorption capacity raises the strength of the depressed chewing layer is determined. As soon as this metal layer has good absorption capacity through the solution is consumed, the precipitate from the dispersion stops automatically, and it is then not possible, the Kautschulzschicht despite arbitrarily increased exposure time to reinforce. If one proceeds in this way, it is therefore not necessary to to monitor the production during precipitation from the rubber milk. There is also the advantage that when working according to this method, a results in a very even product.
\'erv. endet inan das Verfahren gemäß der Erfindung zur Bedeckung von Kupfer mit Kautschuk, so verhindert man, da die Zinkschicht z. B. bei der Elektrolyse vollständig verbraucht wird, ein Anfressen des Kupfers durch das kupferangreifende Vulkanisationsmittel, z. B. Schwefel, dadurch, daß man vor dem Aufbringen der Schicht guter Aufnahmefähigkeit (Zink- j auf das Kupfer noch eine dünne Schicht eines Stoffes aufbringt, der das Kupfer vor Angreifen durch den Schwefel schützt, beispielsweise Zinn. Man kann, um diesen letzteren Arbeitsvorgang zu ersparen, vorteilhaft aber auch stattSchwefel z. B. solche Vulkanisationsbeschleuniger zur Vulkanisation benutzen, die (las Kupfer nicht angreifen.\ 'erv. ends in the method according to the invention for covering of copper with rubber, this prevents the zinc layer from z. B. in electrolysis is completely consumed, corrosion of the copper by the copper attacking Vulcanizing agents, e.g. B. sulfur, in that one prior to applying the layer good absorption capacity (zinc j on the copper still a thin layer of a substance applies, which protects the copper from attack by the sulfur, for example Tin. Man can, in order to save this latter operation, but also advantageous instead of sulfur e.g. B. such vulcanization accelerators for Use vulcanization that does not attack copper.
