Description

Verfahren zur Herstellung von Wachstuch-, Lacklederersatz und Kunstleder. Die Erfindung hat ein Verfahren zur Herstellung von Wachstuch-, Lacklederersatz und Kunstleder zum Gegenstande.Process for the production of oilcloth, patent leather substitutes and artificial leather. The invention has a method for the production of oilcloth, patent leather substitutes and artificial leather to the subject.

Derartige Kunststoffe wurden seither hauptsächlich aus einer Mischung von Celluloseester und Rizinusöl hergestellt. Rizinusöl zeigt jedoch den Nachteil, daß es ranzig wird und verharzt, was ein Brüchigwerden der Folie zur Folge - hat. Außerdem sind die mit Rizinusöl herge$tellten Folien nicht wärmebeständig. Werden sie erhöhter Temperatur ausgesetzt, so schwitzt das Rizinusöl aus und die Folie verliert ihre Geschmeidigkeit. Weiterhin kommt noch hinzu, daß Rizinusöl außerordentlich teuer ist.Since then, such plastics have mainly been made from a mixture made from cellulose ester and castor oil. However, castor oil has the disadvantage that it becomes rancid and gummy, which causes the film to become brittle. In addition, the films made with castor oil are not heat-resistant. Will if exposed to elevated temperatures, the castor oil will sweat out and the film loses its suppleness. Furthermore, castor oil is extraordinary is expensive.

Als Ersatz für Rizinusöl sind Phenolester vorgeschlagen worden. Von diesen kommen aber nur einige von ganz bestimmten Eigenschaften für die Verwendung in Betracht; ihr Preis ist äußerdem ein sehr hoher, so daß sie gegenüber Rizinusöl kaum irgendwelchen Vorteil bieten. Wegen seines hohen Preises scheidet auch Sebacinsäureester, welcher ebenfalls als Ersatz für Rizinusöl vorgeschlagen worden ist, für die praktische Verwendung aus.Phenol esters have been suggested as a substitute for castor oil. from However, these are only a few of the very specific properties that come into play into consideration; Their price is also very high, so that they are compared to castor oil hardly offer any advantage. Because of its high price, sebacic acid ester also separates, which has also been suggested as a substitute for castor oil, for the practical Use off.

Es ist nun gefunden worden, daß Naphthensäureester ein wohlfeiler Ersatz für Rizinusöl bei der Herstellung von Wachstuch-, Lacklederersatz und Kunstleder von besonders vorteilhaften Eigenschaften ist.It has now been found that naphthenic acid ester is a cheaper one Substitute for castor oil in the manufacture of oilcloth, patent leather substitutes and artificial leather is of particularly advantageous properties.

Um diese Stoffe zu gewinnen, stellt man eine geschmeidige Mischung von Celluloseester und Naphthensä,ureester in einem geeigneten Lösungsmittel her; zu dieser werden Farbstoffe und Füllmittel hinzugefügt, worauf man die Mischung auf cine Stoffunterlage aufträgt und das Lösungsmittel verdunsten läßt.In order to obtain these substances, one makes a smooth mixture from cellulose esters and naphthenic acid esters in a suitable solvent; dyes and fillers are added to this, after which the mixture is made applies to a fabric backing and allows the solvent to evaporate.

Es läßt sich sowohl Nitrocellulose als auch Acetylcellulo:e verwenden; als Naphthcnsäurecster kommt in erster Linie derjenige dcs Glycerins in Betracht, sonst aber auch jeder andere Ester mit einem ein- oder mehrwcrtigen Alkohol, wie Glykol, Mannit usw.Both nitrocellulose and acetylcellulose can be used; as the naphthenic acid ester, that of glycerol comes into consideration first and foremost, but otherwise any other ester with a mono- or polyhydric alcohol, such as Glycol, mannitol, etc.

Beispielsweise verfährt män wie folgt Es werden zoo kg z5 prozentige in AmylacetatgelcsteNitrocelluloseund 5okgNaphthensäureelycerinester gemischt und 3o kg Zinkweiß hinzugefügt. Diese auf ein Gewebe aufgetragene Masse ergibt nach dem Verdunsten des Lösungsmittels einen Stoff, der äußerlich in keiner Weise von dem im Verkehr befindlichen Wachstuch zu unterscheiden ist.For example, men proceed as follows: zoo kg are z5 percent mixed in amyl acetate-gelated nitrocellulose and 5okg naphthenic acid lycerol ester and 3o kg of zinc white added. This mass applied to a fabric yields the evaporation of the solvent a substance that is externally in no way of must be distinguished from the oilcloth on the market.
