Aus Pasten von pulvrigen Vinylchloridpolymerisaten in Weichmachern lassen sich Folien und Überzüge auf Faserstoffen der verschiedensten Art, wie Kunstleder, herstellen. Diese Kunstleder haben iber, insbesondere wenn sie größere Mengen Weichmacher zur Erreichung einer hohen Kältebeständigkeit enthalten, eine sich etwas kalt, feucht und klebrig anfühlende Oberfläche-. Außerdem weisen sie alle einen speckigen Glanz auf, der meist nicht erwünscht ist. Der Oberflächenglanz Vk&\ sich zwar durch nachträgliches mechanisches Aufrauhen (aufgerauhte Mattier- oder Narbwalze) beseitigen, der kalte, feuchte, klebrige Griff bleibt indessen dabei erhalten.From pastes of powdery vinyl chloride polymers in plasticizers, foils and coatings on fibrous materials of the most varied types, such as artificial leather, can be produced. These artificial leathers have a surface that is somewhat cold, damp and sticky to the touch, especially if they contain large amounts of plasticizers to achieve high resistance to cold. In addition, they all have a greasy sheen, which is usually not desired. The surface gloss Vk & \ can be eliminated by subsequent mechanical roughening (roughened matting or grain roller), but the cold, damp, sticky handle is retained.

Es wurde nun gefunden, daß man Folien und Überzüge mit matter, trockener Oberfläche mit trockenem, lederähnlichem Griff erhält, wenn man den praktisch wasserfreien Polyvinylchloridpasten vor der Verarbeitung wäßrige, zweckmäßig etwa 20- bis 6o°/oige Emulsionen von Paraffinen zusetzt. Diese Emulsionen können auch noch höhermolekulare Alkohole, ferner öle, Wachse, Harze u. dgl. enthalten. Besonders gute Effekte erzielt man, wenn man derartige Emulsionen mit den Oxyden bzw. Hydroxyden von Metallen der zweiten bis vierten Gruppe des periodischen Systems kombiniert. Diese Emulsionen werden durch Einrühren in der Paste homogen verteilt. Zur Herstellung derIt has now been found that you can use foils and coatings with a matt, dry surface dry, leather-like handle is obtained when using the practically anhydrous polyvinyl chloride pastes prior to processing, aqueous, expediently about 20 to 60% emulsions of paraffins are added. These emulsions can also contain alcohols of even higher molecular weight, as well as oils, waxes, resins and the like. contain. Particularly good effects are achieved if such emulsions are mixed with the oxides or Hydroxides of metals of the second to fourth groups of the periodic table combined. These emulsions are homogeneously distributed in the paste by stirring. To manufacture the

Pasten können alle für Polyvinylchlorid geeigneten Weichmacher benutzt werden. Die Weiterverarbeitung der mit den Emulsionen versetzten Pasten erfolgt wie bisher üblich. Außer der erwünschten trockenen, matten Oberfläche mit lederähnlichem Griff erzielt man noch den· Vorteil, daß die Folien und Überzüge wasserabweisend werden. Wasser perlt an ihnen ab, was für die Verwendung der Erzeugnisse ■ für Regenschutzkleidung wichtig ist. ίο Auch neigt die Paste nicht zum Durchschlagen durch Gewebe.All plasticizers suitable for polyvinyl chloride can be used. The further processing the pastes mixed with the emulsions are carried out as usual. Except the desired one dry, matte surface with a leather-like feel, you get the advantage that the foils and coatings become water-repellent. Water runs off them, which is good for the use of the Products ■ is important for rain protection clothing. ίο The paste also does not tend to strike through through tissue.

Nach dem Auftragen der Paste auf Gewebe Und Erhitzen auf i6o° wird ein Kunstleder erhalten mit einer matten, trockenen und nicht klebenden Oberfläche.A paste consisting of 55 parts of polyvinyl chloride and 45 parts of a plasticizer mixture from dioctyl phthalate and adipic acid diethylhexyl ester in a ratio of 1: 1 with 10 parts of a 60% paraffin emulsion added. After this Applying the paste to fabric and heating it to 160 °, an artificial leather is obtained with a matt, dry and non-sticky surface.

After applying the paste and gelling, a film becomes more matt, dry and non-sticky surface. Similar results are obtained with pastes from 65 parts of copolymer, 35 parts of plasticizer and 5 parts of paraffin emulsion.
