KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. PATENTSCHRIFTPATENT LETTERING - JVH 09827- JVH 09827 KLASSE 39: üHorn und plastische Massen,CLASS 39: üHorn and plastic materials, *> Patentirt im Deutschen Reiche vom *> Patented in the German Empire from 9. Juli 1898 ab.July 9, 1898 onwards. Zum Aufarbeiten von Gummiabfällen ist versucht worden, diese durch Leinöl in Lösung zu bringen und aus der Lösung das Gummi durch Alkohol auszufällen. Aus dem Gemenge von Leinöl und Alkohol soll der Alkohol durch Abdestilliren entfernt werden. Es ist dies ein sehr umständliches und ^kostspieliges Verfahren, welches aus diesem Grunde auch keinen Eingang in die Praxis gefunden hat. Dagegen gestaltet sich der vorstehend beschriebene Procefs wesentlich einfacher, wenn das Leinöl nicht erst durch Alkohol abgeschieden, sondern ebenfalls in eine gummiartige Masse verwandelt wird. Bekanntlich wird Leinöl durch Kochen mit Schwefel oder durch Versetzen mit Chlorschwefel in krümelige, mehr oder weniger elastische Massen verwandelt, die bereits als Kautschukersatzstoffe Verwendung finden. Die Qualität der so erhaltenen Kautschuksurrogate ist aber eine sehr minderwerthige, so sehr man sich auch bemüht hat, dieselbe dadurch zu verbessern, dafs das Leinöl erst oxydirt wurde, oder dafs man die Einwirkung des Chlorschwefels unter Abkühlung und Neutralisation der entstehenden Salzsäure stattfinden liefs. Immer erhält man nur eine bröcklige, leicht zerreifsbare, wenig elastische Masse von ganz geringer Festigkeit. Wird dagegen Gummi in Form zerkleinerter Abfälle mit Leinöl erwärmt, so dafs sich eine dickflüssige Leinölgummilösung bildet und letztere mit Schwefel oder Chlorschwefel behandelt, so erhält man eine Kautschukmasse, welche infolge ihres Gehalts an regenerirtem Gummi alle nach bekannten Verfahren bisher hergestellten Leinölgummisurrogate an Elasticität und Festigkeit bei Weitem übertrifft. Demnach hat dieses Verfahren gegenüber den bisherigen Methoden zur Herstellung von Kautschukmassen folgende Vortheile: Es gestattet die Aufarbeitung von Gummiabfällen auf sehr einfache und billige Weise durch Auflösen derselben in Leinöl, ohne dafs eine Abscheidung des Leinöls nothwendig ist; es liefert ferner ein wegen seines Gehalts an regenerirtem Gummi ganz wesentlich werthvolleres Product, als es bisher durch Behandlung von Leinöl allein mit Schwefel oder Chlorschwefel erhalten werden konnte.Attempts have been made to recycle rubber waste by using linseed oil in solution to bring and to precipitate the gum from the solution with alcohol. From the mix the alcohol should be removed from linseed oil and alcohol by distillation. It is this is a very cumbersome and expensive process, which for this reason too has not found its way into the practice. In contrast, the one described above is designed Procefs much easier if the linseed oil is not separated by alcohol, but is also transformed into a rubbery mass. As is well known linseed oil is made into crumbly, crumbly, more or less elastic masses that were already used as rubber substitutes Find use. However, the quality of the rubber surrogates obtained in this way is very high inferior, however much one has tried to improve it by the fact that the linseed oil was first oxidized, or that the action of the sulfur chloride was cooled down and neutralization of the hydrochloric acid formed allowed to take place. You always get only a crumbly, easily broken, not very elastic mass of very little strength. If, on the other hand, rubber in the form of shredded waste is heated with linseed oil, a forms viscous linseed oil gum solution and treats the latter with sulfur or chlorosulfur, in this way a rubber compound is obtained which, owing to its content of regenerated rubber, has all been made according to known processes linseed oil rubber surrogates produced by far exceeds in elasticity and strength. Accordingly, this process has compared to the previous methods for the production of Rubber compounds have the following advantages: It allows the processing of rubber waste in a very simple and cheap way, by dissolving them in linseed oil, without any Separation of the linseed oil is necessary; it also delivers a because of its salary regenerated rubber is a much more valuable product than it has hitherto been through treatment could be obtained from linseed oil with sulfur or chlorosulfur alone. Zur Ausführung des Verfahren werden 100 Theile Leinöl mit 20 bis 50 Theilen Gummiabfällen so lange erwärmt, bis sich die Gummiabfälle darin vollständig aufgelöst haben. Die Leinölgummilösung wird nun entweder direct mit Schwefel so lange vorsichtig versetzt, bis die Masse genügend consistent ist, oder sie wird erst erkalten gelassen und erst dann mit Chlorschwefel behandelt. Die zuzusetzende Menge von Schwefel oder Chlorschwefel richtet sich theils nach der Menge der Gummiabfälle, theils nach der beabsichtigten Consistenz, welche die fertige Kautschukmasse zeigen soll. Statt Leinöl läfst sich jedes mit Schwefel reagirende OeI anwenden.To carry out the process, 100 parts of linseed oil with 20 to 50 parts are used Heated rubber waste until the rubber waste in it has completely dissolved. The linseed oil gum solution is now either carefully mixed directly with sulfur until until the mass is sufficiently consistent, or it is first allowed to cool down and only then treated with sulfur chloride. The amount of sulfur or chlorosulfur to be added depends partly on the amount of rubber waste, partly on the intended amount Consistency that the finished rubber compound should show. Instead of linseed oil, you can use any one Use sulfur-reacting oils.
