Description

Verfahren zur Herstellung von mehrschichtigen Überzügen oder Imprägnierungen Bekanntlich macht es erhebliche Schwierigkeiten, mehrschichtige Überzüge oder Imprägnierungen, die an der Oberfläche nicht zum Kleben neigen dürfen, herzustellen, wenn man weichmacherreiche Grundschichten verwendet. Wenn man beispielsweise bei der Herstellung von Wachstuchen oder Kunstledern eine stark weichmacherhaltige Lösung oder wäßrige Dispersion eines an sich harten Polymerisats, beispielsweise Polyvinylacetat, verwendet, so gelingt es nicht, darauf eine auf die Dauer glänzend und klebfrei ,bleibende Deckschicht, beispielsweise aus anderen Polymerisaten, aus Celluloseestern oder äthern oder Kondensationsprodukten aus Harnstoff und Formaldehyd, zu erzeugen. Der Weichmacher in der Grundschicht hat offenbar das Bestreben, in die weichmacherärmere Deckschicht abzuwandern, wodurch diese trüb, klebrig und zu weich wird.Process for the production of multilayer coatings or impregnations As is well known, it creates considerable difficulties in multi-layer coatings or impregnations, which must not tend to stick to the surface, if one is rich in plasticizers Base layers used. If you look at the manufacture of oilcloths, for example or artificial leather a highly plasticized solution or aqueous dispersion of a polymer that is hard per se, for example polyvinyl acetate, is used not it, on top of it a permanently shiny and non-sticky top layer, for example from other polymers, from cellulose esters or ethers or condensation products from urea and formaldehyde. The plasticizer in the base layer apparently tends to migrate into the plasticizer-poor cover layer, whereby it becomes cloudy, sticky and too soft.

Es wurde gefunden, daß man mehrschichtige, nicht zum Kleben neigende Überzüge und Imprägnierungen unter Verwendung weichmacherhaltiger Grundschichten herstellen kann, wenn man zwischen den weichmacherhaltigen Grundschichten und den Deckschichten eine Zwischenschicht aus Superpolyamiden oder Superpolyurethanen anbringt. Diese Zwischenschicht kann aus einer Lösung oder wäßrigen Dispersion erzeugt werden. Auch kann man dünne Superpolyamid. oder -urethanfilme aufkaschieren..It has been found that there are multilayered ones that do not tend to stick Coatings and impregnations using base layers containing plasticizers can be produced if you put between the plasticized base layers and the Top layers an intermediate layer made of super polyamides or super-polyurethanes attaches. This intermediate layer can be produced from a solution or an aqueous dispersion will. You can also use thin super polyamide. laminate or urethane films ..

Diese Zwischenschicht verhindert das Durchschlagen von Weichmachungsmitteln, Ölen oder Fetten, bituminösen Stoffen od. dgl., die in den Grundschichten enthalten sein können, in die Deckschicht. Dadurch, daß diese Stoffe nun nicht mehr in@die Deckschicht .dringen können, bleibt diese in ihrer Beschaffenheit unverändert.This intermediate layer prevents plasticizers from penetrating, Oils or fats, bituminous substances or the like contained in the base layers can be in the top layer. Because these substances are no longer in @ the If the top layer can penetrate, the nature of this remains unchanged.

Das Verfahren eignet sich zur Herstellung von Kunstlader oder Wachstuch, zur Kaschierung von weichmacherhaltigen Folien mit weichmacherarmen oder weichmacherfreien Folien, zur Herstellung von elastischen mit einer weichmacherhaltigen Folie aus organischen Stoffen. Im letztgenannten Falle :dringt bei Verwendung der Zwischenschicht aus Superpolyamiden oder -urethanen zwischen der Folie und der Klebschicht das Weichmachungsmittel nicht in die Klebschicht ein, wodurch :diese zu stark erweichen und ihre Zähigkeit verlieren würde. Die Klebschicht bleibt vielmehr unverändert.The process is suitable for the production of art loaders or oilcloth, for lamination of plasticizer-containing films with plasticizer-poor or plasticizer-free Films, for the production of elastic with a plasticizer-containing film organic matter. In the latter case: penetrates when using the intermediate layer made of super polyamides or urethanes between the film and the adhesive layer, the plasticizer does not penetrate into the adhesive layer, which: it softens too much and its toughness would lose. Rather, the adhesive layer remains unchanged.

Beispiel i Ein Gewebe wird viermal mit einer Streichmasse aus i5oTeilen einer 5oo%igen wäßrigen Dispersion von Polyvinylacetat, a5 Teilen Trikresylphosphat, 15 Teilen Dibutylphthalat, So Teilen Talkum und 3o Teilen Lithopone bestrichen. Nach dem Trocknen und Kalandern wird ein dünner Zwischenstrich aus einer Lösung von 2o Teilen eines Superpolyamids aus 6o Teilen adipinsaurem Hexamethylendiamin und 4o Teilen e-Aminocapronsäure in So Teilen .Methanol aufgebracht und bei etwa 70° ;getrocknet. Schließlich wird mit einem handelsüblichen, klebfrei auftrocknenden Glanzlack aus Nitrocellulose abgedeckt und das Ganze gegebenenfalls genarbt. Man erhält so ein klebfrei bleibendes Wachstuch oder Kunstleder.Example i A fabric is coated four times with a coating of 150 parts a 500% aqueous dispersion of polyvinyl acetate, a5 parts of tricresyl phosphate, 15 parts of dibutyl phthalate, 50 parts of talc and 3o parts of Lithopone coated. After drying and calendering, a thin intermediate line is created from a solution of 2o parts of a superpolyamide from 6o parts of adipic acid hexamethylenediamine and 40 parts of e-aminocaproic acid in parts of .Methanol and applied at about 70 °; dried. Finally, a commercially available, non-sticky drying agent is used Gloss varnish made of nitrocellulose covered and the whole thing grained if necessary. Man This way you get a non-sticky oilcloth or synthetic leather.

In ;gleicher Weise kann man auch eine Lösung eines ,Superpolyurethans aus Hexamethylendiisocyanat und Hexamethylenglykol verwenden. Beispiel 2 Eine Dispersion von 5o Teilen Polyvinylchlorid in 5o Teilen Trikresylphosphat wird einseitig- auf eine Gewebebahn gebracht und die Masse bei etwa 116o° ausgelatiniert. Die Rückseite der Gewebebahn wird ,dann mit einer Lösung von a3 Teilen eines Superpolyamids aus 6:o Teilen adipinsaurem Hexamethylendiamin und 4o Teilen E-Aminocapronsäure in So Teilen Sao/oigem wäßrigem Methanol, die mit einer Lösung von 3 Teilen eines Kondensationsproduktes aus Propansulfamid und Dimethylolharnstoff in 15 Teilen Methanol versetzt wurde, gestrichen und getrocknet. Nach dem Trocknen bringt man darauf zwei Aufstriche einer 4oo/oigen Lösung eines Mischpolymerisats aus 6o Teilen Vinylacetat und 4o Teilen Acrylsäurebuthylester in Essigester auf, trocknet und pudert mit Talkum. Man erhält so einen geschmeidigen, klebfrei .bleibenden Stoff, der sich als Regenmantelstoff, Zeltstoff und als Waggonbedeckung eignet.In the same way one can also use a solution of a super-polyurethane from hexamethylene diisocyanate and hexamethylene glycol. Example 2 A dispersion of 50 parts of polyvinyl chloride in 50 parts of tricresyl phosphate is one-sided brought a web of fabric and the mass gelatinized at about 116o °. The backside the fabric sheet is then made with a solution of a3 parts of a superpolyamide 6: o parts of adipic acid hexamethylenediamine and 40 parts of E-aminocaproic acid in So Parts of Sao / oigem aqueous methanol with a solution of 3 parts of a condensation product was added from propanesulfamide and dimethylolurea in 15 parts of methanol, painted and dried. After drying, you put two spreads on top of it 400% solution of a copolymer of 60 parts of vinyl acetate and 40 parts Acrylic acid butyl ester in ethyl acetate, dries and powdered with talc. You get such a supple, non-sticky fabric that can be used as a raincoat fabric, Tent fabric and suitable as a wagon covering.

Beispiel 3 Eine etwa o,4 mm dicke Folie aus 6o Teilen Polyvinylchlorid, 25 Teilen Trikresylphosphat und 15 Teilen Dibutylphthalat wird mit einer Lösung aus 1i3 Teilen eines Superpolyamids aus 5o Teilen adipinsaurem Hexamethylendiamin und 5o Teilen s-Aminocapronsiä@ure in $2 Teilen einer Mischung aus 5 Teilen Methanol, 4 Teilen Chloroform und i Teil Wasser überzogen und getrocknet. Dann bringt man eine Klebemasse aus Kautschuk, Polyisobutylen, mineralischen Ölen, Harzen und Zinkoxyd auf. Man erhält ein Verbandmaterial, das seine ursprüngliche Adhäsion und Kohäsion beim Lagern unverändert behält. B,eispiel4 Eine Celluloidtafel wird einseitig mit einer Superpolyamidlösung gemäß Beispiel i überzogen. Nach dem Trocknen wird auf die Superpolyamidschicht eine Folie aus 6o Teilen Polyvinylchlorid und 4o Teilen Trikresylphosphat aufkaschiert. Man erhält eine geschmeidige Platte, die klebfrei bleibt. In gleicher Weise kann die Polyvinylchloridfolie auch mit :einer zweiten Celluloidfolie versehen ,verden. An Stelle der Superpolyamidlösung kann auch eine Superpolyamidfolie verwendet werden. Beispiels Naturseide wird zweimal mit einer 5oo/oigen alkoholischen Lösung eines Umsetzungsproduktes aus ,ioo,Teilen Harnstoff-Formaldehyd-H.arz und ioo Teilen Trimethylolpropanadipinsäureester, dem 25 Teile Trikresylphosphat zugesetzt wurden, imp:#ägniert und nach Verdunsten .des Alkohols io Minuten ibei,il?,o° zur Härtung des Umsetzungsproduktes -erwärmt. Dann wird beidseitig durch Streichen oder Tauchen ein dünner Zwischenstrich aus einer Lösung von 15 Teilen eines Superpolyamids aus 6o, Teilen adipinsaurem Hexamethylendiamin und 4o. Teilen E-Aminocapronsäure in $5 Teilen Methanol aufgebracht und bei 7o bis 3o° getrocknet. Anschließend wird mit einem klebfrei auftrocknenden Nitrocelluloselack abgedeckt. Es wird eine klebfrei bleibende Ölseide für technische oder Bekleidungszwecke erhalten..Example 3 An approximately 0.4 mm thick film made of 60 parts of polyvinyl chloride, 25 parts of tricresyl phosphate and 15 parts of dibutyl phthalate are mixed with a solution from 1i3 parts of a superpolyamide from 50 parts of adipic acid hexamethylenediamine and 50 parts of s-aminocaproic acid in 2 parts of a mixture of 5 parts of methanol, 4 parts of chloroform and 1 part of water coated and dried. Then you bring an adhesive made from rubber, polyisobutylene, mineral oils, resins and zinc oxide on. A dressing material is obtained that retains its original adhesion and cohesion remains unchanged during storage. B, ebeispiel4 A celluloid tablet is one-sided with a superpolyamide solution according to Example i coated. After drying it will be on the superpolyamide layer is a film made from 60 parts of polyvinyl chloride and 40 parts Laminated tricresyl phosphate. A pliable sheet which is tack-free is obtained remain. In the same way, the polyvinyl chloride film can also have: a second Celluloid foil provided, verden. Instead of the superpolyamide solution, a Super polyamide film can be used. Example natural silk is used twice with one 500% alcoholic solution of a reaction product from 100 parts of urea-formaldehyde-resin and 100 parts of trimethylolpropane adipic acid ester, the 25 parts of tricresyl phosphate were added, imp: # ägniert and after evaporation of the alcohol 10 minutes ibei, il?, o ° -heated to harden the reaction product. Then it is done on both sides by painting or dipping a thin intermediate coat from a solution of 15 parts of a superpolyamide from 6o, parts of adipic acid hexamethylenediamine and 4o. Parts of E-aminocaproic acid applied in $ 5 parts of methanol and dried at 7o to 3o °. Then will covered with a tack-free drying nitrocellulose varnish. It becomes a tack-free one permanent oil silk preserved for technical or clothing purposes ..
