Description
Verfahren zur Herstellung eines elastischen kautschukartigen Körpers. Im Hauptpatent ist ein Verfahren be schrieben, gemäss welchem man zu einem elastischen, kautschukartigen Körper gelangt, der sich zum Beispiel auch auf den in der Cxummi-Industrie gebräuchlichen Maschinen wie natürlicher Kautschuk verarbeiten, sowie reit Füllstoffen, z.
B. Zinkoxyd, Russ, Mag nesia usw., sowie mit natürlichem Kautschuk, Faktis, Regeneraten usw. mischen, formen und vulkanisieren lässt, wenn man Schwefel oder schwefelabgebende Stoffe auf Äthylen- dichlorid in Gegenwart eines wässerigen, al kalischer), alkoholischen oder andern Lösungs mittels zur- Einwirkung bringt.
Es wurde nun gefunden, dass man zu eiuern ähnlichen Körper gelangt, wenn man in jenem Verfahren - statt Äthylendi- chlorid - ein Gemisch von Formaldehyd und Äthylendichlorid verwendet, auf das man Schwefel oder schwefelabgebende Sub stanzen in Polysulfidform, in der Wärme oder bei gewöhnlicher Temperatur, einwirken lässt. Das erhaltene Produkt ist ein kautschuk. artiger, elastischer, in Schwefelkohlenstoff löslicher Körper.
<I>Beispiel:</I> Auf 100 Teile einer wässerigen, alkoholi schen oder alkalischen Lösung, welche Schwe fel enthält und zum Beispiel als Lösung von Schwefelealcium in Polysulfidform dadurch erhalten wird, dass man Kalli:hydrat mit Schwefel und Wasser kocht und die Lösung filtriert, wird ein Gemisch von 3 Teilen For maldehyd und 3 Teilen Äthylendichlorid unter Erwärmen zur Einwirkung gebracht. Es entsteht ein kautschukartiger, elastischer Körper, der in Schwefelkohlenstoff löslich ist. Die Modifikation des angewandten Schwefels wird bestimmend für den Grad der Löslich keit des gebildeten kautschukartigen Körpers in Schwefelkohlenstoff.
Die Umwandlung kann auch bei gewöhnlicher Temperatur durch Stehenlassen während einiger Tage durch geführt werden.
Method for producing an elastic rubber-like body. In the main patent, a method is be written, according to which one arrives at an elastic, rubber-like body that can be processed, for example, on the machines commonly used in the Cxummi industry, such as natural rubber, as well as fillers such.
B. zinc oxide, soot, magnesia, etc., as well as mix, shape and vulcanize with natural rubber, factice, regenerates, etc., if you have sulfur or sulfur-releasing substances on ethylene dichloride in the presence of an aqueous, alkaline), alcoholic or other Solution by means of action.
It has now been found that one arrives at a body similar to egg if one uses in that process - instead of ethylene dichloride - a mixture of formaldehyde and ethylene dichloride, on which one stamps sulfur or sulfur-releasing substances in polysulphide form, in the warmth or at ordinary temperature to act. The product obtained is a rubber. like, elastic body soluble in carbon disulfide.
<I> Example: </I> For 100 parts of an aqueous, alcoholic or alkaline solution which contains sulfur and which is obtained, for example, as a solution of sulfur-calcium in polysulphide form by boiling calli: hydrate with sulfur and water and the Solution filtered, a mixture of 3 parts of formaldehyde and 3 parts of ethylene dichloride is brought to action with heating. The result is a rubber-like, elastic body that is soluble in carbon disulfide. The modification of the sulfur used is decisive for the degree of solubility of the rubber-like body formed in carbon disulfide.
The conversion can also be carried out at ordinary temperature by allowing it to stand for a few days.
