Description

Verfahren zur Herstellung von fest haftenden Aufstrichen aus weichgemachtem Polyvinylchlorid auf Geweben Es ist bekannt, weichgemachte Polyvi,nylchloridmassen, wie sie z. B. zur Kunstlederbereitung herangezogen werden, zur Beschichtung von Geweben zu verwenden. Es ist auch bereits vorgeschlagen worden, zur Verbesserung der Haftfestigkei@tderartiger Gewebebeschichtungen der Polyvi-nylehlori,d@paste Polyester und Polyisocyänate zuzusetzen, jedoch zeigen derartige Beschichtungen. auf Geweben verschiedener Herstellung, wie z. B. auf Kunstseide aus Cellulosederivaten oder auf Polyamiden, keine oder nur eine ungenügende Haftung.Process for the production of firmly adhering spreads from plasticized Polyvinyl chloride on fabrics It is known to use plasticized Polyvi, nylchloridmassen, how they z. B. are used for synthetic leather preparation, for coating of Tissues to use. It has also been suggested for improvement the adhesive strength of such fabric coatings from Polyvi-nylehlori, d @ paste Adding polyesters and polyisocyanates, however, show such coatings. on fabrics of various manufacture, such as B. on rayon made from cellulose derivatives or on polyamides, no or only insufficient adhesion.

Es wurde nun gefunden, da.B fest haftende Aufstriche aus weichgemachtenPolyvinylchloridstreich= massen durch Mitverwendung von Polyurethanen auf Gewebere dadurch hergestellt werden können, daß die Gewebe mit einer Lösung von-Oxy- oder Carboxylendgruppen enthaltenden Polyestern vorbehandelt und dann mit einer Polyisocyanate enthaltenden Polyvinylchloridpaste bestrichen werden.It has now been found that B firmly adhering spreads made from plasticized polyvinyl chloride spreads = masses can be produced by using polyurethanes on fabrics can that the tissue with a solution containing oxy or carboxyl end groups Pre-treated polyesters and then with a polyvinyl chloride paste containing polyisocyanates be coated.

Die erfindungsgemäß zu verwendenden Polyester mit endständigen Oxy- oder Carboxylendgruppen werden in bekannter Weise durch Verestern von Polycarbonsäuren und Polyalkoholen erhalten. Es genügt, wenn das Polyisocyanat dem ersten .der Polyvinylchlorid-Aufstriche zugesetzt wird. Die Verarbeitung geschieht in der für Polyvinylchlorid üblichen Weise unter Anwendung höherer Temperatur. Durch diese Behandlung werden beschichtete Materialien erhalten, bei denen es kaum möglich ist, die Kunststoffaufstriche von der Unterlage abzulösen und. die eine derartig gute Haftfestigkeit auch bei Verwendung von Polyamiden und Kunstseidengeweben als Unterlage aufweisen.The polyester to be used according to the invention with terminal oxy- or carboxyl end groups are established in a known manner by esterifying polycarboxylic acids and polyalcohols obtained. It is sufficient if the polyisocyanate is added to the first of the polyvinyl chloride spreads is added. The processing takes place in the usual way for polyvinyl chloride Way using higher temperature. Through this treatment coated materials are obtained for which it is hardly possible to use plastic spreads to be removed from the base and. which also has such a good adhesive strength Have use of polyamides and rayon fabrics as a base.

Beispiel i izaigt dieerfindiungsgemäße Beschichtung eines Polyamidgewebes. Beispiel :2 gibt einen Vergleichsversuch wieder, der die nach dem neuen Verfahren erzielte verbesserte "Haftfestigkeit aufzeigt. Beispiel i Ein Polyamidgewebe wird mit einer 5%igen Lösung eines linear aufgebauten Polyesters aus Adipinsäure und i, 6-Hexandiol mit o,6% O H-Gehalt und der Säurezahl i9 in Butylacetat oder inanderen gebräuchlichen Lösungsmitteln bestrichen oder gespritzt. Nach dem Verdunsten des *Lösungsmittels wird mit einer Masse bestrichen, die wie folgt hergestellt wird: Zu einer mit Dibutylphthalat weichgemachten Polyvinylchloridpaste (Verhältnis 6o : 40), .in welcher Farbstoffe, Pigmente usw. in üblicher Weise einges:rbeitet sind, werden 5% Toluylendiisocyanat zugegeben. Statt des genannten Weichmachers können alle üblichen gebräuchlichen-Weichmacher, wie Dioctylphthalat, Trikresylphosphat, Paraffinsulfosäurephenylester, Benzyloctyladipat verwendet werden. Nach guter Verteilung ist,die Masse zum Aufstreichen auf das vorbehandelte Gewebe fertig. Der zweite und die weiteren Polyvinylchlorid-Aufstriche können ohne Zusatz von Toluylen,di.isocyanat durchgeführt werden. Anschließend wird in üblicher Weise bei den, einzelnen Strichen vorgetrocknet und zum Schluß bei i6o bis 17a° C 3 bis 5 Minuten geliert.Example i izaigt the inventive coating of a polyamide fabric. Example: 2 shows a comparative test that was carried out using the new procedure shows improved "adhesive strength achieved. Example i A polyamide fabric is with a 5% solution of a linear polyester composed of adipic acid and i, 6-Hexanediol with 0.6% O H content and the acid number 19 in butyl acetate or in others brushed or sprayed with common solvents. After the * Solvent is coated with a mass that is prepared as follows: To a polyvinyl chloride paste plasticized with dibutyl phthalate (ratio 6o : 40), in which dyes, pigments etc. are incorporated in the usual way, 5% tolylene diisocyanate are added. Instead of the plasticizer mentioned, you can all common plasticizers, such as dioctyl phthalate, tricresyl phosphate, Paraffin sulfonic acid phenyl ester, benzyl octyl adipate can be used. After good distribution is, the mass is ready to be spread onto the pretreated fabric. The second and the other polyvinyl chloride spreads can be used without the addition of toluene, di.isocyanate be performed. Then in the usual way with the, individual lines predried and finally gelled at 160 to 17 ° C for 3 to 5 minutes.

Das beschriebene Verfahren kann in der Weise abgeändert werden, daß man nachdem Aufbringen des ersten Aufstriches 5 Minuten bei i2o° C trocknet und anschließend eine Polyvinylchloridfolie in üblicher Weise auf dem: Ka:lan.der bei Temperaturen von 165 bis i75° C aufkaschiert. Es wird auf diese Weise eine feste Haftung der Polyvinylchloridfolie auf der Unterlage erzielt. Beispiele Ein Polyamidgewebe wird mit einer Weichmacher enthaltenden Polyvinylchloridpaste, die pro ioo g 5 g eines Oxygruppen enthaltenden Polyesters und 5 g Toluylendiisocyanat enthält, bestrichen. Anschließend werden zwei weitere Aufstriche mit der gleichen Polyvinylchloridpaste, jedoch ohne Zusatz von Polyester und Toluylendiisocyan.at, aufgebracht. Nach jedem Auftrag wird. 30 Minuten bei go° C getrocknet und nach .der gesamten. Beschichtung zusätzlich 4 Minuten lang bei- i75° C. Die nach diesem Verfahren erhaltenen Aufstriche besitzen eine Haftfestigkeit von i,$ kg/cm Reißbreite.The method described can be modified in such a way that after the first spread has been applied, it is dried for 5 minutes at 120 ° C and then a polyvinyl chloride film in the usual way on the: Ka: lan.der bei Laminated at temperatures from 165 to 175 ° C. It becomes a solid that way Adhesion of the polyvinyl chloride film to the base achieved. Examples A polyamide fabric is with a plasticizer-containing polyvinyl chloride paste, which per ioo g 5 g of a polyester containing oxy groups and 5 g of tolylene diisocyanate, coated. Then two more spreads are made with the same polyvinyl chloride paste, but without the addition of polyester and toluylene diisocyanate. After every Order will. Dried for 30 minutes at go ° C and after the entire. Coating an additional 4 minutes at -175 ° C. The spreads obtained by this method have an adhesive strength of 1.6 kg / cm tear width.

In einem zweiten Versuch werden die gleichen Polyarnidgewebe und die gleichen Polyvinylchloridpasten unter Einshaltung der gleichen Versuchsbedingungen angewandt. Es wird jedoch das Polyamid gewebe zunächst mit einer 5%igen Lösung des in dem ersten Versuch verwendeten Polyesters in Äthylacetat/Methylenchlorid (i : i) vorbehandelt und für den ersten Aufstrich eine Polyvinylchloridpaste verwendet, die lediglich 5 g Töluylendiisocyanat, jedoch keinen Polyester enthält. Nach diesem Verfahren wird eine Haftfestigkeit von 2,8 kg/cm Reißbreite erzielt.In a second experiment, the same polyamide fabric and the same polyvinyl chloride pastes while observing the same test conditions applied. However, it is the polyamide fabric first with a 5% solution of the polyester used in the first attempt in ethyl acetate / methylene chloride (i: i) pretreated and a polyvinyl chloride paste used for the first spread, which contains only 5 g of töluylene diisocyanate, but no polyester. After this This method achieves an adhesive strength of 2.8 kg / cm tear width.
