Description

Verfahren zur Herstellung von Lösungen großer Klebekraft aus solchen im Handel befindlichen künstlichen Kautschuksorten, die in den üblichen Lösungsmitteln schwer oder unvollkommen löslich sind, oder deren Lösungen keine genügende Klebekraft besitzen. Während man den natürlichen Kautschuk in Benzin, Benzol, Solventnaphtlia, Tetrachlorkohlenstoff-usw. ohne Schwierigkeit lösen und so eine brauchbare Kleblösung erhalten kann, ist dies bei einigen im Handel erhältlichen Sorten von künstlichem Kautschuk nicht der Fall. Diese lösen sich in den genannten Lösungsmitteln nur unvollkommen und äußerst langsam auf, ferner besitzt die so erhaltene Lösung nicht die genügende Klebkraft, die z. B. zum Herstellen von Kasten aus einzelnen Platten erforderlich ist. Gegenstand vorliegender Erfindung ist ein Verfahren, aus den genannten künstlichen Kautschuksorten rasch Lösungen herzustellen, welche eine hohe Klebkraft besitzen. Es gründet sich auf die neue Beobachtung, daß diese Kautschtfksorten eine dein natiirlichen -Kautschuk gleichkommende Löslichkeit in den üblichen Lösungsmitteln erhalten, und daß die so hergestellten Lösungen eine gute Klebkraft besitzen, wenn die genannten Kautschuksorten auf eine mindestens ihren Schmelzpunkt erreichende Temperatur in Luft bei einen i Druck von etwa einer Atmo-,sphäre erhitzt werden, wobei sie in einem gleichmäßig durchscheinenden Stoff übergehen. Das Zierfahren besteht demnach in einer vorgänglichen Erhitzung unter den genannten Umständen und der darauffolgenden Lösung ' in den üblichen Lösungsmitteln. Das Erhitzen kann auf Wärmeplatten, in Trokkenschräilken; Vülkanisationskesseln mit indirekter Dampfzuführung usw. geschehen. Beispielsweise wird der künstliche Kautschuk-. zu einem dünnen Fell ausgewalzt und auf einer Wärmeplatte auf etwa 14o° erhitzt, bis er durchscheinend ist. Nach dem Erkalten wird das Produkt in kleine Teile zerschnitten und in üblicher Weise in Benzin oder in einem anderen passenden Mittel gelöst.Process for the preparation of solutions of great adhesive strength from such Artificial rubbers on the market that are in the usual solvents are difficult or imperfectly soluble, or their solutions do not have sufficient adhesive strength own. While the natural rubber in gasoline, benzene, solvent naphthia, Carbon tetrachloride etc. solve without difficulty and so a usable adhesive solution can be obtained, this is with some commercially available varieties of artificial Rubber is not the case. These dissolve only imperfectly in the solvents mentioned and extremely slowly, and the solution thus obtained is insufficient Adhesive strength z. B. required for making boxes from individual plates is. The present invention is a method from the mentioned artificial Types of rubber to quickly produce solutions that have a high adhesive strength. It is based on the new observation that this type of chew is one of your natural ones -Rubber equivalent solubility obtained in the usual solvents, and that the solutions prepared in this way have a good bond strength when said Rubber grades to a temperature that at least reaches their melting point in Air can be heated at a pressure of about one atmosphere, being in to an evenly translucent fabric. The ornamental driving therefore exists in a previous heating under the circumstances mentioned and the subsequent one Solution 'in the usual solvents. Heating can be done on hot plates, in Trokkenschräilken; Vülkanisationskessel with indirect steam supply etc. happen. For example, the artificial rubber. rolled out into a thin fur and heated on a hot plate to about 14o ° until it is translucent. After this When cooling, the product is cut into small pieces and in the usual way Gasoline or any other suitable means.
