Description

Dichtungsmittel für Kautschukschläuche Es sind Dichtungsmittel für Kautschukschläuche bekannt, die aus Lösungen von Schellack, Dextrin, Seife o. dgl. in organischen Flüssigkeiten bestehen.Sealants for rubber hoses There are sealants for Known rubber hoses, which are made from solutions of shellac, dextrin, soap, or the like. exist in organic liquids.

Gegenüber diesen Mitteln, deren Grundsubstanzen vielseitige Verwendungsmöglichkeiten haben und namentlich in Kriegszeiten sparsam verwendet werden müssen, besteht das Dichtungsmittel gemäß der Erfindung aus einer alkoholischen Chinoidinlösung. Dieses Mittel ,ist billig und in reichlichen Mengen zu haben, da Chinoidin, ein alkaloidisches Besengemisch, laufend als Nebenprodukt bei der Extraktion von Chinarinde nach den üblichen- Verfahren anfällt. Seine Überlegenheit über die bekannten Mittel besteht in seiner Haltbarkeit, wie Versuche bewiesen haben, in seinem günstigen chemischen und physikalischen Verhalten gegenüber Kautschuk, eine Tatsache, die dem Chinoidin schon früh Eingang in die Gummiindustrie als Vulkanisationsbeschleuniger, Füllstoff und als Mittel gegen Alterung verschafft hat, und ferner darin, daß die mit diesem Mittel behandelten Kautschukerzeugnisse im Gegensatz zu anderen, wie üblich, regeneriert werden können.Compared to these means, their basic substances versatile uses and must be used sparingly, especially in times of war, that exists Sealant according to the invention from an alcoholic quinoidin solution. This Medium, is cheap and available in plentiful quantities, since quinoidin, an alkaloid Broom mixture, continuously as a by-product in the extraction of cinchona bark according to the usual procedures. Its superiority over the known means is there in its durability, as tests have shown, in its favorable chemical properties and physical behavior towards rubber, a fact common to the quinoidin Early entry into the rubber industry as a vulcanization accelerator, filler and as a means against aging, and furthermore that those with this Agent treated rubber products unlike others, as usual, regenerated can be.

Von einer .etwa zo%igen .alkoholischen Lösung des Chinoidins wird zum Abdichten nur eine Menge .gebraucht, die genügt, um die Innenfläche eines Kraftfahrzeug- oder Fahrradluftschlauches vollständig mit einer dünnen Schicht zu überziehen. Für einen gewöhnlichen Fahrradschlauch füllt man etwa io ccm Lösung durch das Ventilloch des Schlauches ein. Nach dem Einschrauben. des Ventils wird der Reifen hart aufgepumpt. Aus der beim Drehen des Fahrzeugrades sich auf der Innem$äche des Schlauches gut verteilenden Lösung dringt das Chinoidin in die feinen Poren und Risse des Schlauches ein und dichtet sie ab-.From an about ten percent alcoholic solution of the chinoidins for sealing, only an amount needed that is sufficient to seal the inner surface of a motor vehicle or to completely cover the bicycle air tube with a thin layer. For A normal bicycle tube is filled with about 10 cc of solution through the valve hole of the hose. After screwing in. the valve inflates the tire hard. From the turning of the vehicle wheel on the inner surface of the hose well distributing solution penetrates the quinoidin into the fine pores and cracks of the tube and seals it.

Als Lösungsmittel für Chinoidin verwendet man zweckmäßigerweise Methylalkohol.The solvent used for quinoidin is expediently methyl alcohol.
