Description

Verfahren zum Herstellen von Platten o. dgl. aus Kauuschukdispersionen Es ist bekannt, Kautschukgegenstände in Form von Bändern, Fäden 0. dgl. durch Auftragen von Kautschukmilch auf nichtsaugende, bandartige Unterlagen, Trocknen und Abziehen der entstandenen Kautschukerzeugnisse von den bandartigen Unterlagen herzustellen. Diese Arbeitsweise bedingt jedoch die Verwendung von Koagulationsmitteln, die vor dem Trocknen der Kautschukschicht erst wieder ausgewaschen werden müssen, und liefert außerdem keine Erzeugnisse mit glatten Oberflächen.Process for the production of plates or the like from Kauuschuk dispersions It is known to apply rubber articles in the form of tapes, threads, etc. by applying them of rubber milk on non-absorbent, tape-like substrates, drying and peeling off of the resulting rubber products from the tape-like substrates. However, this procedure requires the use of coagulants, which are before the rubber layer must first be washed out after drying, and delivers in addition, no products with smooth surfaces.

Demgegenüber lerhält man erfindungsgemäß Platten 0. dgl. mit vollkommen glatten Oberflächen in sehr einfacher Weise dadurch, daß die Kautschukdispersion auf eine aus einer Schicht yon Cellulosehydrat bestehende bandartige Unterlage aufgetragen, auf der Unterlage getrocknet und dann davon abgezogen wird. Die Verwendung einer aus Gellulosehydrat bestehenden Unterlage hat gegenüber der von Unterlagen anderer Art den besonderen Vorzug, daß der Wassergehalt der Kautschukdispersion von der Unterlage unter Quellen derselben rasch aufgesaugt wird, ohne daß dabei Kautschuk in die Unterlage selbst eindringt, und das Ablösen der gebildeten Kautschukplatte von der Unterlage erschwert oder verhindert. In contrast, according to the invention, plates 0. Like are obtained with perfect smooth surfaces in a very simple manner in that the rubber dispersion applied to a tape-like base consisting of a layer of cellulose hydrate, is dried on the base and then peeled off. Using a The pad consisting of cellulose hydrate has a different base from that of the pads of others Art has the particular advantage that the water content of the rubber dispersion depends on the Pad is quickly absorbed by swelling the same, without the rubber penetrates into the base itself, and the detachment of the rubber sheet formed made difficult or impossible by the support.

Man erhält auf diesem Wege in einfacher Weise Kautschukplatten o. dgl. mit beiderseits glatter und klebender Oberfläche. In this way, rubber sheets or the like are obtained in a simple manner. Like. With a smooth and adhesive surface on both sides.

Das Auftragen der Kautschukdispersion kann durch Aufspritzen, Streichen mit der Auftragwalze, durch Gießen oder durch Ziehen der Cellulosehydratbahn über die Oberfläche eines Bades erfolgen. Die letztere Arbeitsweise ist besonders vorteilhaft, um beiderseitig glatte Oberflächen herzustellen, und es kann in diesem Falle die Stärke der Platte durch die Geschwindigkeit der Bahn, durch die Konzentration der Dispersion und durch die Anzahl der aufgetragenen Schichten geregelt werden. The rubber dispersion can be applied by spraying or brushing with the applicator roller, by pouring or by pulling the cellulose hydrate sheet over the surface of a bath. The latter working method is particularly advantageous, in order to produce smooth surfaces on both sides, and in this case the Strength of the plate by the speed of the web, by the concentration of the Dispersion and can be regulated by the number of layers applied.

Das Trocknen der Kautschukschicht auf der saug- und quellfähigen Unterlage aus Cellulosehydrat kann durch Anwendung von Wärme beschleunigt werden, indem man die bandförmigen Unterlagen z. B. über heizbare Tische oder Trommeln leitet. The drying of the rubber layer on the absorbent and swellable Cellulose hydrate base can be accelerated by applying heat, by the tape-shaped documents z. B. passes over heated tables or drums.
