Zahlreiche klebrige Stoffe, wie Asphalt, Bitumen, Teer, Wachs, Paraffine, Klebstoffe, Kautschuk und andere unvulkanisierte Polymere, sowie tiefgekühlte Nahrungsmittel haften an Papier und Pappe an, so daß zu deren Verpackung besonders behandelte blattförmige Cellulosematerialien verwendet werden, die als sogenannte Trennpapiere bezeichnet werden. Diese können beispielsweise als Umhüllungen oder als Zwischenlagen zwischen Schichten der genannten oder anderer an Papier anklebender Materialien verwendet werden.Numerous sticky substances, such as asphalt, bitumen, tar, wax, paraffins, adhesives, and rubber other unvulcanized polymers and frozen foods adhere to paper and cardboard, see above that specially treated sheet-like cellulose materials are used for their packaging, the are referred to as so-called release papers. These can, for example, as sheaths or as Interlayers are used between layers of the named materials or other materials that adhere to paper will.
Trennpapiere verschiedener Art sind bereits bekannt. So ist es bereits beschrieben, blattförmiges Cellulosematerial in einem Dreistufenverfahren mit feingemahlenem Ton und Casein, danach mit feingemahlenem Ton und schließlich mit Polyvinylacetat zu beschichten. Diese Trennpapiere haben aber den Nachteil, daß bei ihrem Ablösen von den klebrigen Materialien das Polyvinylacetat auf diesen Materialien zurückbleibt. Andere bekannte Verfahren zur Her-Stellung von Trennpapier bestehen darin, das blattförmige Cellulosematerial mit mehreren Schichten von Polyäthylen oder mit einer ersten Schicht aus Ton und einer zweiten Schicht aus Methylcellulose und Stärke zu versehen. Die so hergestellten Trennpapiere erwiesen sich jedoch oft als ungenügend, insbesondere bei staik klebenden Materialien, wie Asphall, da sie sich nur unvollständig von solchen Materialien trennen lassen.Release papers of various types are already known. So it is already described, leaf-shaped Cellulose material in a three-step process with finely ground clay and casein, then with finely ground Clay and finally to coat with polyvinyl acetate. However, these release papers have the Disadvantage that when they are detached from the sticky materials, the polyvinyl acetate on these materials remains behind. Other known methods for the manufacture of release paper are the sheet-shaped Cellulosic material with several layers of polyethylene or with a first layer made of Clay and a second layer of methyl cellulose and starch. The release papers produced in this way However, they often proved to be insufficient, especially in the case of staik adhesive materials such as Asphall, as they cannot be completely separated from such materials.
Aus der deutschen Patentschrift 876 503 ist außerdein bereits ein Verfahren zur Herstellung von Trennpapieren durch Behandeln blattförmigen Cellulosematerials in einem aus einer wäBrigcn Polysiloxanemulsion bestehenden Bad bekannt. Hierbei wird Methylwasserstoffpolysiloxan in Verbindimg mit wasserlöslichen Celluloscülhern verwendet. Auch die so hergestellten bekannten Trennpapiere besitzen jedoch eine Reihe von Nachteilen. So sind ihre Iienntij t nst tuiHt η It iinbd itdiiti und nicht an iiitn I im ( η dti ' κmipipidobufliehe gleich.

Finally, it should be mentioned that from "plastics". 1957, H. 8. pp. 431 to 434, dibutyltin diluurut is known as a vulcanization catalyst for silicone rubber and that in a number of Publications such as in French patents 1,129,476, 1,087,484 and 1 061 035, U.S. Patent 2,672,455 and German Patent 925 225 and 878 791, Polysiloxanes are described as water repellants for textiles and leather. These technical areas however, have completely different properties with regard to the properties required for release papers nothing in common with the subject of the invention.

Treatment of the sheet-like cellulose material with the polysiloxane emulsion is carried out in a manner known per se, for. B. by dipping, spraying and troweling.
Nach dem Behandeln in der wäßrigen Emulsion wird das blattförmige Cellulosematerial vorteilhafterweise 10 Sekunden bis 3 Minuten oder länger über erhitzte Rollen von einer Temperatur zwischen 90 und 1750C geführt und getrocknet. Auch kann zur Trocknung zirkulierende Heißluft von 100 bis 1600C verwendet werden, die gewöhnlich 30 Sekunden bis 5 Minuten auf das behandelte Cellulosemateria! einwirkt. Im Gegensatz zu den oben beschriebenen bekannten Trennpapieren sind die so hergestelltenAfter treatment in the aqueous emulsion, the sheet-like cellulose material is advantageously passed over heated rollers at a temperature between 90 and 175 ° C. for 10 seconds to 3 minutes or longer and dried.

The polydimethylsiloxanes with terminal hydroxyl groups can be obtained by treating high molecular weight polydimethylsiloxanes with water.

It is advantageous to use these methylpolysiloxane resins in a solvent such as Toluene, xylene or a mixture of toluene and butanol, up to concentrations of 10 to 90 percent by weight to solve.
Als blattförmiges Cellulosematerial kann beispielsweise Pergamentpapier, Packpapier, Leinenpapier, Reispapier, Pergamin oder Zellglas oder Pappe verwendet werden.For example, parchment paper, wrapping paper, linen paper, Rice paper, glassine or cellulose glass or cardboard can be used.
Gegenüber den vorbekannten Trennpapieren besitzen die nach der Erfindung gewonnenen den Vorteil, bessere und sogleich nach ihrer Herstellung auftretende Trenneigenschaften zu besitzen, die auch bei längerer Lagerung nicht verschwinden. Außerdem wurde im Gegensatz zu den bekannten Trennpapieren keine Wanderung der Polydimethylsiloxane und Methylpolysiloxanharze an die Oberfläche des Cellulosematerials beobachtet. Ein weiterer Vorteil derCompared to the previously known release papers, those obtained according to the invention have the advantage to have better and immediately after their production occurring release properties, which also with do not disappear after long periods of storage. In addition, in contrast to the well-known release papers no migration of the polydimethylsiloxanes and methylpolysiloxane resins to the surface of the cellulose material observed.
