Description

Verfahren zum Mattieren von biegsamen Polystyrolfolien oder -bändern Es ist bekannt, aus Polystyrol durch allseitiges Recken biegsame Bänder und Folien herzustellen. Ein Nachteil dieser Gebilde besteht darin, daß sie eine sehr glatte Oberfläche 'haben,- die es erschwert, irgendwelche Schichten anderer Art festhaftend darauf anzubringen. Beispielsweise ist es nicht ohne weiteres möglich, solche Bänder oder Folien aus Polystyrol 'mit Farbe zu bedrucken oder Metallschichten auf ihnen niederzuschlagen. Andererseits bewirkt die Glätte der Oberflziche ein starkes Kleben an anderen ebenfalls glatten Flächen, was in vielen Fällen hinderlich ist.Process for matting flexible polystyrene films or tapes It is known to produce flexible tapes and films from polystyrene by stretching on all sides to manufacture. A disadvantage of these structures is that they are very smooth Surface '- which makes it difficult to stick any other kind of layers to attach to it. For example, it is not readily possible to use such tapes or foils made of polystyrene 'to be printed with color or metal layers on them knock down. On the other hand, the smoothness of the surface causes strong adhesion on other equally smooth surfaces, which is a hindrance in many cases.

Es ist zwar' schon bekannt, Gegenstände < zitis Polystyrol zu färben. Zu diesem Zwecke «erden mit Farbstoffen versetzte Lösungen von Polystyrol auf die zu färb--nden Gegenstande gespritzt. Falls man gleichzeitig eine Aufrauhung der gespritzten Polystyrolteile wünscht, wird zu den gefärbten Lösungen ein Zu&ltz von Benzol gegeben. Bei diesem bekannten Verfahren werden die Polystyrolkörper jedoch in ihren Abmessungen durch das Aufspritzen verlndert, -so daß es sich bei sehr dünnen Polystyrolfolien nicht ohne Nachteil anwenden läßt, ohne derartige Folien durch die aufgespritzte Schicht in ihrer Gleich-1näßigkeit und Stärke nachteilig zu Verändern. Man hat auch schon vorgeschlagen, aus Kunstharzen bestehenden Formmassen Metallpulver zuzusetzen und auf die Gegenstände, die .aus diesen leitend gemachten Formmassen hergestellt sind, Metallüberzüge auf galvanischem . Wege niederzuschlagen. Derartige Formkörper sind aber für elektrotechnische Zwecke nicht brauchbar.While it is' already known to color objects <zitis polystyrene. For this purpose, solutions of polystyrene mixed with dyes are sprayed onto the objects to be colored. If the injection-molded polystyrene parts are to be roughened at the same time, benzene is added to the colored solutions. In this known method, however, the dimensions of the polystyrene bodies are changed by the spraying process, so that it cannot be used without disadvantage in the case of very thin polystyrene films without the uniformity and thickness of such films being adversely affected by the sprayed-on layer. It has also already been proposed to add metal powder consisting of synthetic resins and to apply metal coatings on the objects that are made from these conductive molding compounds. Knock down ways. Such shaped bodies cannot be used for electrotechnical purposes.

Zur Behebung dieser Nachteile wird erfindungsgemäß vorgeschlagen, Folien oder Bänder aus Polystyrol dadurch zu mattieren, daß eine oder beide Oberflächen der Folien kurze Zeit mit einem Lösungsmittel für das Polystyrol behandelt werden. Als Losungsmittel kommen z. B. Benzol, Amylacetat oder deren Mischungen in Frage, welche in diüiner Schicht auf die Oberflächen der Folien aufgebracht oder in welche die Folien für kurze Zeit eingetaucht werden. Die Oberfläche der Folien verändert sich unter der Einwirkung des Lösungsmittels; nach dessen Verdunstung ist ihr Aussehen seidenartig und mattglänzend. Auf der so vorbereitete Oberlläche ist es ohne Schwierigkeiten möglich, einen Aletallb:lag nach bekannten Verfahren, beispielsweise durch Aufspritzen oder chemisches Niederschlagen, festhaftend anzubringen. Soll die hletallisierung auf elektrochemischem Weg erfolgen, so ist die Oberfläche der Folien zuvor elektrisch leitend zu machen, beispielsweise durch Aufstreichen von Graphit. Ebenso ist es möglich, die erfindungsgemäß vorbereiteten Folien mit Farbe zu bedrucken oder anderweitig zu beschriften. Ferner haben die Folien unter der Einwirkung des Lösungsmittels die unangenehme Eigenschaft verloren, an,anderen glatten Flächen zu kleben.To remedy these disadvantages, it is proposed according to the invention that Polystyrene foils or tapes to be matted by making one or both surfaces the foils are treated with a solvent for the polystyrene for a short time. The solvents used are e.g. B. benzene, amyl acetate or their mixtures in question, which are applied in a thin layer to the surfaces of the foils or in which the foils are immersed for a short time. The surface of the foils changed himself under the action of the solvent; after its evaporation is their appearance silky and matt-glossy. It is easy on the surface prepared in this way possible, an Aletallb: lay according to known methods, for example by spraying or chemical deposition, to be attached firmly. Should the metallization take place electrochemically, the surface of the foils is electrical beforehand to make leading, for example by painting graphite. It is also possible to print the films prepared according to the invention with color or otherwise labeled. Furthermore, under the action of the Solvent has lost its unpleasant property on other smooth surfaces to glue.

Die mattierten Folien gemäß der Erfindung können auf vielen Gebieten der Elektrotechnik Verwendung finden beispielsweise eignen sie sizh zur Bewicklung von Kabeladern, wobei die Folien zwecks Unterscheidung der einzelnen Adern mit verschiedenen Farben oder Zeichen bedruckt sein können. Metallisierte Folien können in der Elektrotechnik ebenfalls vorteilhaft Verwendung finden. Beispielsweise kann man sie- als elektrostatische Schirme in Fernmeldekabeln verwenden. Vor den bekannten Schirmen aus metallisiertem Papier haben sie den Vorzug, nicht hygroskopisch zu sein. Weiterhin eignen sich die metallisierten Folien zur Herstellung von Kondensatoren. Für diesen Zweck empfiehlt es sich, beide Seiten der Folien mit einer Metallschicht vorzugsweise einer Silberschicht; zu überziehen. Trotz der verhältnismäßig nicdrigeen Dielektrizitätskonstante des Polystyrols kann man auf diese Weise gleichwohl eine hohe spezifische Kapazität des Kondensators erzielen, da der Abstand der beiden Metallbelegungen nicht größer als die Dicke der Folien ist; diese kann aber sehr gering, beispielsweise o, o r mm stark, gehalten werden.The matted films according to the invention can be used in many fields in electrical engineering, for example, they are suitable for wrapping of cable cores, with the foils to distinguish the individual cores with different Colors or characters can be printed. Metallized foils can be used in electrical engineering also find advantageous use. For example, they can be called electrostatic Use shields in communication cables. In front of the well-known shields made of metallized Paper has the advantage of not being hygroscopic. Furthermore are suitable the metallized foils for the manufacture of capacitors. Recommended for this purpose it is possible to have both sides of the foils with a metal layer, preferably a silver layer; to cover. Despite the relatively low dielectric constant of the In this way, polystyrene can nonetheless have a high specific capacity of the capacitor, as the distance between the two metal layers is not greater than the thickness of the foils; but this can be very low, for example o, o r mm thick.
