Description

Überzüge und Formkörper aus weichmadherhaltigem Polyvinylchlorid, beispielsweise Kunstleder daraus, zeigen, wenn sie viel Weichmacher enthalten, was zur Erzielung einer guten Kälte-Inständigkeit von Vorteil ist, ein - deutliches Adhäsionsvermögen, d. h. eine gewisse Neigung /um Kleben. Außerdem besteht bei derartigen Erzeugnissen auch noch die Gefahr, daß die Weichmacher durch den Einfluß von Lösungsmitteln, u. a. ίο auch von Ölen und Fetten, herausgelöst werden können, wodurch eine Versprödung eintritt. Deshalb kann man manche Artikel aus diesen Massen, z.B. Druckwalzen, nur in solchenFällen anwenden, l>ei denen sie nicht mit Lösungsmitteln in Berührung kommen.Coverings and moldings made from soft mather material Polyvinyl chloride, for example synthetic leather made from it, show if they have a lot of plasticizer contain what helps to achieve a good cold instinct it is advantageous to have a - significant adhesiveness, d. H. a certain tendency / to sticking. In addition, there is such Products also run the risk of the plasticizers being damaged by the influence of solvents, among other things. ίο can also be extracted from oils and fats can, whereby embrittlement occurs. Therefore, some articles can be made from these masses, e.g. pressure rollers, only use in cases where they are not in contact with solvents come.

Es wurde nun gefunden, daß man Überzüge und Formkörper dieser Art, die beständig gegen den Einfluß der praktisch gebräuchlichen Lösungsmittel sind und keine Neigung zum Ankleben haben, aus weichmachertialtigen Vinylchloridpolymerisaten erhält, wenn man einen Überzug aus Polyamiden daraufbringt. It has now been found that coatings and moldings of this type that are resistant to the Influence of the solvents commonly used in practice and have no tendency to stick contains plasticizer-grade vinyl chloride polymers, if you put a coating of polyamides on it.

Es bereitet jedoch häufig Schwierigkeiten, die Polyamidschicht unlösbar fest auf Überzügen und Formkörpern aus weichmacherhaltigen Vinyl-Chloridpolymerisaten anzubringen, da die Poly-However, it often causes difficulties, the polyamide layer inextricably fixed on coatings and To attach moldings made of plasticizer-containing vinyl chloride polymers, as the poly-

amide mit den Vinylchloridpolymerisaten im allgemeinen nicht recht verträglich sind.amides are generally not very compatible with the vinyl chloride polymers.

Es wurde weiter gefunden, daß man auch diese Schwierigkeit beseitigen kann, wenn man zwischen die Schicht aus weichmacherhaltigen Vinylchloridpolymerisaten und die Polyamiddeckschicht eine Zwischenschicht aus weichmacherhaltigen Vinylchloridpolymerisaten bringt, die Polyamide enthält. Die Polyamide sind in dieser Schicht infolge ihrer ίο weitgehenden Unverträglichkeit mit den Vinylchloridpolymerisaten praktisch als Füllstoffe in feiner Verteilung enthalten, bewirken aber eine feste Verankerung der Polyamiddeckschicht.It has also been found that this difficulty can also be eliminated if one between the layer of plasticizer-containing vinyl chloride polymers and the polyamide cover layer one Brings intermediate layer of plasticizer-containing vinyl chloride polymers that contains polyamides. The polyamides are in this layer due to their extensive incompatibility with the vinyl chloride polymers practically contained as fillers in a fine distribution, but cause a firm anchoring of the polyamide cover layer.

Beispiel ιExample ι

Auf eine Gewebebahn wird ein Grundstrich aus einer Paste von 50 Teilen Polyvinylchlorid und 50 Teilen Weichmacher aufgetragen. Darauf bringt man eine Paste der gleichen Zusammensetzung, die soviel einer alkoholischen Lösung eines Polyamids aus Caprolactam und adipinsaurem Diaminodicyclohexylmethan enthält, daß der Gehalt an festem Polyamid etwa 2% beträgt. Daraufbringt man noch eine Paste sonst gleicher Zusammensetzung, die jedoch 5% Polyamid enthält. Als Deckschicht wird ein Strich mit einer Lösung des vorstehend genannten Polyamids in wäßrigem Methanol aufgebracht. Nach der vollständigen Durchgelierung bei etwa 160 bis i8o° wird ein Kunstleder mit einer glänzenden, klebefreien Oberfläche erhalten. Man kann auch das gleiche Kunstleder mit matter Oberfläche erzeugen, wenn man der Polvamidlösung etwas kolloidalen Ton, wie er z. B. unter dem Namen Bentonit bekannt ist, beimisdit. A base coat made from a paste of 50 parts of polyvinyl chloride and 50 parts of plasticizer applied. A paste of the same composition as as much as an alcoholic solution of a polyamide from caprolactam and adipic acid diaminodicyclohexylmethane contains that the solid polyamide content is about 2%. Brings up another paste of the same composition, but containing 5% polyamide. as The top layer is a coating with a solution of the aforementioned polyamide in aqueous Methanol applied. After complete gelation at about 160 to 180 °, a Artificial leather obtained with a glossy, tack-free surface. You can also use the same synthetic leather with a matt surface, if you add some colloidal clay to the polvamid solution, like him z. B. known under the name bentonite, beimisdit.

Beispiel 2Example 2

Zur Herstellung einer Druckwalze wird dieTo produce a pressure roller, the

schwach erhitzte Form für die Walze zunächst mit einer Paste aus 50 Teilen Polyvinylchlorid und 50 Teilen Weichmacher, die 10% von dem im Beispiel 1 genannten Polyamid in Form einer Lösung enthält, ausgeschwenkt. Es bildet sichhierbei an der Wand der Form ein Überzug, dessen Stärke je nach dem Grad der Anwärmung der Form verschieden gehalten werden kann. Nac'h Einbringen des Formkernes wird die Form dann in bekannter Weise mit einer weichmacherhaltigen Paste aus Polyvinylchlorid gefüllt und auf i6o°erhitzt. Nach Abkühlen bringt man auf die so erhaltene Walze eine Lösung des gleichen Polyamids in wäßrigem Methanol auf. Man erhält so einen Überzug, der außerordentlich fest haftet und die Walze gegen die Einwirkung der gebräuchlichsten Lösungsmittel ausgezeichnet schützt.Slightly heated mold for the roller first with a paste of 50 parts of polyvinyl chloride and 50 parts of plasticizer, the 10% of the polyamide mentioned in Example 1 in the form of a Contains solution, swiveled out. This forms a coating on the wall of the mold, its thickness can be held differently depending on the degree of heating of the mold. After bringing in of the mold core, the mold is then made in a known manner with a paste containing plasticizer Filled with polyvinyl chloride and heated to 160 °. After cooling, it is brought onto the roller thus obtained a solution of the same polyamide in aqueous methanol. This gives a coating that extremely firmly adheres and the roller against the action of the most common solvents excellent protection.

Beispiel 3Example 3

Auf eine Folie aus weichmacherhaltigem Polyvinylchlorid wird eine dünne Schicht aus einer Paste von 60 Teilen Polyvinylchlorid und 40Teilen Weichmacher, die 20 Teile des im Beispiel 1 genannten Polyamids in Form einer Lösung in wäßrigem Methanol enthält, aufgetragen. Auf diese Schicht, die gegebenenfalls durch Erwärmen leicht angeliert sein kann, wird eine Folie aus einem Polyamid aus Caprolactam gelegt. Durch Erhitzen auf i6o° unter leichtem Druck in einer Presse oder zwischen zwei Walzen wird die Zwischenschicht ausgeliert, wobei gleichzeitig eine festhaftende Verbindung mit der Polyamidfolie erzielt wird.A thin layer of a Paste of 60 parts of polyvinyl chloride and 40 parts of plasticizer, the 20 parts of the in Example 1 contains said polyamide in the form of a solution in aqueous methanol, applied. on this layer, which can optionally be slightly gelled by heating, becomes a sheet of one Polyamide laid from caprolactam. By heating to 160 ° under slight pressure in a press or The intermediate layer is gelled between two rollers, with one firmly adhering at the same time Connection with the polyamide film is achieved.
