Description

Wundpflaster aus Vinyl- und Akrylpolymerisaten Zur Herstellung von Wundpflastern eignen sich Polyvinyl- und Polyakrylprodukte deshalb besonders, weil sich diese Stoffe durch hohe Elastizität, hohe Lagerfähigkeit, Durchsichtigkeit, Abwaschbarkeit usw. auszeichnen.Adhesive plasters made from vinyl and acrylic polymers For the production of Polyvinyl and polyacrylic products are particularly suitable for wound plasters because these fabrics are characterized by high elasticity, long shelf life, transparency, Excellent for washability, etc.

Es hat sich jedoch gezeigt, daß die Haftfähigkeit für Klebstoffe an derartigen Pflastern nicht sehr groß ist mit dem Erfolg, daß ein aufgeklebtes Pflaster sich leicht verschiebt.However, it has been shown that the adhesiveness for adhesives such plasters are not very successful with the success that a stick-on plaster shifts easily.

Gemäß vorliegender Erfindung ist, um dem vorzubeugen, das aus Polyvinyl- oder Akrylprodukten bestehende Pflaster auf der der Klebstoffschicht zugekehrten Seite aufgerauht.According to the present invention, in order to prevent the polyvinyl plaster or plaster made of acrylic products on the one facing the adhesive layer Roughened side.

Die Herstellung dieser Aufrauhung kann dadurch erfolgen, daß man die gelösten Folymerisate auf eine geraubte Gummiunterlage aufgießt rund nach dem Trocknen abzieht.The production of this roughening can be done by the Pour dissolved Folymerisate on a stolen rubber pad around after drying withdraws.

Die auf diese Weise hergestellten Filme besitzen infolge der Anwendung der geraubten Unterlagen einseitig eine raube Oberfläche, welche nicht nur das Haftvermögen für den zur Anwendung kommenden Klebstoff, siondern auch das Haftvermögen des Pflasters auf der menschlichen Haut beträchtlich erhöht.The films produced in this way have due to the application the stolen documents have a rough surface on one side, which not only increases the adhesive strength for the adhesive used, the adhesive strength of the plaster also siondern increased considerably on the human skin.

Beispiel In Chloroform gelöster Piolyakrylessigester wird auf eine geraubte Gummiunterlage ausgegossen. Es bildet sich nach der Verdunstung des Lösungsmittels ein Film von annähernd gleicher Stärke, der nach dem Ablösen, bedingt durch die rauhe Unterlage, einseitig eine raube Oberfläche aufweist. Dieser Film wird mit Klebstoff versehen, und zwar geschieht dies zweckmäßig durch Aufspritzen oder dadurch, daß man den Film durch nächst dem Behälterboden angeordnete Schlitze eines Behälters hindurchführt, der mit zähem Klebstoff gefüllt ist. Infolge der Zähigkeit des Klebstoffes kann dieser nur mit der einen Filmseite in Berührung treten. Als Klebstoff verwendet man solchen, wie er bei den üblichen Pflastern bereits verwendet ist. Er besteht aus einem Gemisch von Kautschuk, Zinkoxyd, Wollfett, Dammarharz, Kollophoniwm,gelöst in Benzin. Nach dem Aufbringen des Klebstoffes wird getrocknet. Dies ist sehr zweckmäßig, um nachträglich das Zuschneiden des Films, einwandfrei durchführen zu können. Das Schneiden erfolgt in möglichst kühlem Raum, damit Klebstoff und Film möglichst steif sind. Auch soll der Raum möglichst trocken sein. Das Zerschneiden ge chieht mit Hilfe von rotierenden Messern, die den Film in Streifen zerschneiden. Diese werden sodann mit der Schere oder mit derselben Vorrichtung quer geschnitten. Nach dem Zerschneiden wird auf das mit Klebstoff versehene einzelne Pflaster ein Gazestreifen aufgelegt.Example Piolyakrylessigester dissolved in chloroform is applied to a stolen rubber pad poured out. It forms after evaporation of the solvent a film of approximately the same thickness after peeling, due to the rough surface, rough surface on one side. This movie will be with Provided with adhesive, this is expediently done by spraying on or by that one the film through next to the container bottom arranged slots of a container passes through, which is filled with tough glue. Due to the toughness of the adhesive this can only come into contact with one side of the film. Used as an adhesive one such as is already used with the usual plasters. He exists from a mixture of rubber, zinc oxide, wool fat, dammar resin, Kollophoniwm, dissolved in gasoline. After the adhesive has been applied, it is dried. This is very useful in order to be able to carry out the cutting of the film properly afterwards. That Cutting takes place in a room that is as cool as possible so that the adhesive and film are as stiff as possible are. The room should also be as dry as possible. The cutting is also done With the help of rotating knives that cut the film into strips. These will then cut transversely with scissors or with the same device. After this A strip of gauze is cut onto the individual plaster provided with adhesive hung up.

Das Aufbringen des Klebstoffes erfolgt natürlich auf die geraubte Seite.The application of the adhesive is of course carried out on the stolen Page.

Als Unterlage lassen sich, wenn auch nicht mit dem Vorteil wie eine Gummiunterlage, doch auch mattierte Glasplatten oder Metallplatten, die mit Sandstrahlen behandelt oder auf sonstige Weise raub gemacht sind, verwenden.As a base, although not with the advantage of a Rubber base, but also frosted glass plates or metal plates that are sandblasted treated or otherwise robbed.
