Die Herstellung von Uberzugstoffen für Papier, Gewebe, Holz u. dgl. die aus Leim und Kaseinlösungen mit härtenden Zusätzen oder aus Celluloidlösungen mit erweichenden ölzusätzen oder einer Verbindung von Emulsionen aus wasserunlöslichen Flüssigkeiten in wässerigen Leim- und Kaseinlösungen bestehen, ist an sich' bekannt. Diese können zwar wasserdicht sein,· werden aber bald hart undThe production of coating materials for paper, fabric, wood and the like from glue and casein solutions with hardening additives or from celluloid solutions with emollient oil additives or a combination of emulsions from water-insoluble liquids in consist of aqueous glue and casein solutions, is known per se. These can be waterproof, but will soon become hard and

Die Erfindung betrifft nun ein Verfahren zur Herstellung eines Überzug- oder Imprägnierstoffes, z.B. für Papier, Gewebe, tierische Haut, Geflechte u. dgl., aus Kolloiden bekannter Art, welcher durch die Art und Mengenverhältnisse der verwendeten Stoffe und deren Vereinigung auch als Klebstoff verwendbar und durch eine dabei stattfindende Härtung des verwendeten Weichmittels nicht nur elastisch, sondern auch wasserdicht und kochfest sowie unhygroskopisch und unentflammbar ist, so daß er unter der Einwirkung von Wärme, Luft und Feuchtigkeit unverändert bleibt.The invention now relates to a method for producing a coating or impregnating material, e.g. for paper, fabric, animal skin, braids and the like, better known from colloids Type, which is determined by the type and proportions of the substances used and their Association can also be used as an adhesive and due to the hardening that takes place in the process The softener used is not only elastic, but also waterproof and boil-proof as well as unshygroscopic and non-flammable, so that it can be exposed to Heat, air and humidity remain unchanged.

Das Verfahren besteht im wesentlichen darin, daß Kolloide bekannter Art, z. B. Leim, Gelatine, Celluloid u. dgl., in einer unter Ausschluß von Wasser hergestellten Lösung mit einem mittels Eisessig gelöstem und gebundenem Weichmittel gemischt werden und evtl. noch einen Härtemittelzusatz erhalten. Dieses Weichmittel kann aus Glyzerin oder einem schwer löslichen Öl und das Härtemittel aus Formalin bestehen. Das Erzeugnis dieses Verfahrens ist eine stark klebrige Masse, die' einen elastischen bzw. weichen, geschmeidigen, zähen, durchsichtigen, gehärteten bzw. wasserbeständigen und in ziemlich weitgehendem Maße sogar kochfesten Überzugstoff für Stoffe der oben genannten Art bildet, welcher in kurzer Zeit trocknet.The method consists essentially in that colloids of known type, e.g. B. glue, gelatine, Celluloid and the like, in a solution prepared with exclusion of water with one dissolved and bound by means of glacial acetic acid Softeners are mixed and possibly also contain a hardener additive. This Softeners can be made from glycerine or a poorly soluble oil and the hardener Consist of formalin. The product of this process is a very sticky mass which ' an elastic or soft, pliable, tough, transparent, hardened or water-resistant and to a fairly large extent even boil-proof cover material for fabrics of the type mentioned above, which dries in a short time.

Versieht man z. B. wenig oder gar nicht geleimte oder mit irgendeiner Krepp-, Perl-, Schuppen-, Narben- oder Haut- usw. Pressung versehene Papiere oder Pappen oder Textilstoffe mit einem entsprechenden Überzug dieser Art, so werden diese, auch wenn sie vorher eine gewisse Steifheit besaßen, ganz lederartig weich, zähe, geschmeidig und voll im Griff, so daß derart behandelte Papiere usw. eine richtige Lederimitation bilden, welche zur Herstellung billiger, aber immerhin ganz schoner und haltbarer Täschner- und Buchbinderarbeiten geeignet sind.If you see z. B. little or not glued or with any crepe, pearl, Scales, scars or skin etc. Pressed papers or cardboard or textile materials with a corresponding coating of this type, these will be, even if they were previously had a certain stiffness, very leathery, soft, tough, supple and fully under control, so that papers, etc. treated in this way form a correct imitation leather which is used for Production of cheap, but at least very beautiful and durable bag-making and bookbinding work are suitable.

Behandelt man jene Stoffe vorher etwas mit Natronlauge, so werden sie, bei geringerem Bedarf an Uberzugstoff, noch fester und lederartiger. If you treat these substances with caustic soda beforehand, they become less Need for cover material, even stronger and more leather-like.

Holzartig gepreßten Karton oder Pappe kann man durch Überziehen mit einer dünnen Lösung dieser Art zu einer linkrustaartigen Masse umbilden, das wie echtes Linkrusta von Staub und Schmutz gereinigt sowie ohne weiteres mit beliebigen Anstrichen versehen werden kann.Cardboard or cardboard that has been pressed in the manner of wood can be coated with a thin one Transform this type of solution into a linkrusta-like mass, like real linkrusta cleaned of dust and dirt and easily provided with any paint can be.

at first it is also soft and supple like skin; but you treat it. after this. Dry·. ;; with cold water, it has the smoothness, firmness, toughness and impermeability of good parchment paper. In a similar manner, one can produce washable paper wallpapers, advertising pictures, paper posters and the like with this cover material. Likewise ίο artificial casings made of paper, since the latter becomes boil-proof by being impregnated with the boil-proof solution. If you impregnate a linen, cotton, silk o Balloon fabric as well as fabric for the wings of aircraft is excellently suited. But also for sealing seams on a wide variety of fabrics. In yet another dilution, the mixture is also a very good finishing agent for fabrics, here again especially in cases where the durability of the finishing is important. B. paper yarn fabric and straw hats can be made washable without them by the wetting when drying; shrink or lose shape. As a result of the great tackiness of the coating material, which it possesses in the form of its solution, it also forms an excellent adhesive in a more consistent form, which enables very beautiful, transparent, elastic, water-resistant and boil-proof bonds. These examples are only intended to indicate a few possible applications and are in no way intended to be exhaustive. In the following, some special manufacturing processes for the new coating material are given. For example, celluloid dissolved in acetone and amyl acetate is provided with a castor or eucalyptus oil additive serving as a softening agent, a little glacial acetic acid is added to dissolve the oil and then the whole thing is provided with a small addition of formalin. The necessary dilution of the entire substance can be carried out with acetone. Furthermore, glue or gelatine is dissolved in glacial acetic acid in a closed vessel and then brought to a complete solution on a water bath. A little glycerine is then added to the mixture as a softener and to change the gelatinization, and a small amount of forriialin is added. . ■ Instead of using as indicated here, glue that has been boiled in the steam bath can also be used in water / swollen. The rest of the procedure remains the same. These solutions can be diluted with glycerine. If a little formalin is added to the solutions before use, the coatings dry a little faster at moderate heat than is otherwise the case. But also by stirring the celluloid-oil mixture with the glue-glacial acetic acid-glycerine solution one can obtain such a coating substance if one adds a little sugar lime and zapon to the two, to which mixture a little formalin can be added. ■ '. ■ ■ V patent claims:
