Description

Verfahren zur Herstellung von Kautschukmischungen Bei der Verarbeitung von Kautschuk zu Weichkautschuk oder Weichkautschukwaren ist es erforderlich, außer den sonst üblichen Zusätzen Weichmachungsmittel zuzugeben, um die gewünschte Dehnbarkeit und Geschmeidigkeit zu erzielen.Process for the production of rubber compounds During processing from rubber to soft rubber or soft rubber goods it is necessary except add plasticizers to the usual additives in order to achieve the desired elasticity and to achieve suppleness.

Man hat bereits vorgeschlagen, als Weichmachungsmittel größere Mengen von etwa 2oQ/o rohen Sojaöls Kautschukmischungen zuzusetzen. Dieses Sojaöl, das durch Pressen gewonnen wurde, enthält selbst in ganz frischem Zustande nur äußerst geringe Spuren von Phosphatiden, die schon nach wenigen Stunden oder Tagen durch Oxydation und fermentative Einflüsse zersetzt sind. Die weichmachende Wirkung wird in diesen Fällen ausschließlich durch die sehr große Ölmenge ,erzielt.It has already been proposed to use larger amounts as plasticizers add about 2oQ / o of crude soybean oil to rubber mixtures. This soybean oil that obtained by pressing, even in a very fresh state, contains only extremely small traces of phosphatides that appear after a few hours or days Oxidation and fermentative influences are decomposed. The emollient effect will in these cases only achieved through the very large amount of oil.

Es wurde nun gefunden, da.ß das im Tier- und Pflanzenreich vorkommende Lecithin für diesen Zweck ganz besonders geeignet ist und die -Beschaffenheit des Kautschuks wesentlich zu verbessern vermag. Schon ein Zusatz von etwa o, ¢ % Lecithin zu der Kautschukmasse genügt, um die gewünschte Wirkung zu erzielen. Außerdem hat der Zusatz von Lecithin zu der Kautschukmischung die günstige, bisher unbekannte Wirkung, daß hierdurch eine Beschleunigung der Vulkanisation erreicht wird. Auch werden den mit Phosphatiden nach der vorliegenden Erfindung versetzten Kautschukmischungen, wie eingehende Untersuchungen gezeigthaben und wie auch durch .spätere Veröffentlichungen iin Schrifttum bewiesen ist, vorteilhafte Alterungseigenschaften verliehen.It has now been found that that which occurs in the animal and plant kingdoms Lecithin is particularly suitable for this purpose and the quality of the Able to improve rubber significantly. Even an addition of about 0.0% lecithin to the rubber compound is sufficient to achieve the desired effect. Also has the addition of lecithin to the rubber mixture is the cheapest, previously unknown Effect that this accelerates the vulcanization. Even the rubber compounds mixed with phosphatides according to the present invention, as shown by in-depth research and as well as by later publications It has been proven in literature and has advantageous aging properties.

Für die Ausführung des Verfahrens können Phosphatide jeglicher Art benutzt werden. Insbesondereeignen sich hierfür die aus den Sojabohnen gewonnenen Pflanzenphosphatide; weiterhin kann man auch- für den vorliegenden Zweck die phosphorhaltigen Abfallprodukte der Sojaölfabrikation benutzen.Phosphatides of any kind can be used to carry out the process to be used. In particular, those obtained from soybeans are suitable for this Plant phosphatides; furthermore, one can also use the phosphorus-containing ones for the present purpose Use waste products from soybean oil production.

Die Ausführung des Verfahrens geschieht in der Weise, da.ß das Lecithin zu der Kautschukmasse mit den üblichen Zusätzen vor der Vülkanis.ation hinzugefügt und daß dasselbe in der gesamten Masse gleichmäßig verteilt wird. Die anzuwendende Menge des Lecithins richtet sich nach der Art der Zusammensetzung des Ausgangsstoffes und der gewünschten Beschaffenheit des fertigen Erzeugnisses; sie beträgt o,q.o/o und darüber.The procedure is carried out in such a way that the lecithin added to the rubber mass with the usual additives before the Vülkanis.ation and that it is evenly distributed throughout the whole mass. The applicable The amount of lecithin depends on the type of composition of the starting material and the desired nature of the finished product; it is o, q.o / o and above.

Beispielsweise kann eine Mischung Verwendung finden, welche aus ioo Teilen Kautschuk, 5 - Teilen Magnesia Usta, 6 Teilen Schwefel und 2 Teilen Sojaphosphatiden zusammengesetzt ist.For example, a mixture can be used which consists of ioo Parts of rubber, 5 parts of Magnesia Usta, 6 parts of sulfur and 2 parts of soy phosphatides is composed.
