Description

Verfahren zur Herstellung von gleichzeitig feuerhemmendem und wasserabstoßendem Fasergut Es ist bekannt, Papier, Pappe, Gewebe und andere aus Fasern bestehende Erzeugnisse feuerfest zu machen, indem man diese Materialien mit Salzlösungen, beispielsweise mit Lösungen von Chlorammonium, wolframsaurem Natrium u. a. m., tränkt. Es hat sich aber bisher nicht ermöglichen lassen, dieses Verfahren auf solche Materialien anzuwenden, die man vorher nach den bis jetzt üblichen Methoden, wie zum Beispiel durch Niederschlagen von Aluminiumpalmitat, wasserfest gemacht hat. Entweder nehmen diese wasserfesten Materialien die Salzlösung nicht an, oder aber die Salzlösung zerstört den vorher erzeugten Wasserfestigkeitseffekt; ebenso ist es unmöglich gewesen, das Material zuerst feuerfest und dann wasserfest herzustellen. Ein aus Fasern bestehendes Material, das gleichzeitig wasser- und feuerfest ist, bildete bis heute eine ungelöste Aufgabe der Technik.Process for the production of fire-retardant and water-repellent at the same time Fiber material It is known paper, cardboard, fabric and other fibers made up of fibers Making products refractory by treating these materials with saline solutions, for example with solutions of chlorammonium, sodium tungstate and others. m., soaks. It has but so far not allow this method to be applied to such materials, which have been made beforehand using the methods customary up to now, such as by knocking down made of aluminum palmitate, waterproof. Either take this waterproof one Materials do not use the saline solution, or the saline solution destroys the one before produced water resistance effect; likewise it has been impossible to find the material first refractory and then waterproof. A material made up of fibers which is waterproof and fire-proof at the same time, was an unsolved problem to this day of the technique.

Es hat sich nun überraschenderweise gezeigt, daß bei Anwendung einer besonderen Methode, Textilien, Papier, Pappe u. dgl. wasserfest zu machen, eine Kombination mit Feuerfestigkeit möglich ist. Diese bereits eorgeschlagene Methode besteht darin, daß man die betreffenden Materialien in sehr milder Weise mit veresternd wirkenden Abkömmlingen höherer organischer Säuren behandelt, wobei das behandelte Material in keiner Weise seine Struktur usw. verändert. So behandelte Materialien haben die Eigentümlichkeit, zwar kaltes Wasser abzustoßen, warmes Wasser dagegen, von etwa q.0° C an, in mit der Temperatur steigendem Maße aufzunehmen, nach dem Trocknen aber wieder, wie früher, kühleres Wasser abzustoßen.It has now been shown, surprisingly, that when using a a special method of making textiles, paper, cardboard and the like waterproof Combination with fire resistance is possible. This already suggested method consists in esterifying the materials in question in a very mild manner acting derivatives of higher organic acids treated, the treated Material in no way changes its structure, etc. Materials treated in this way have the peculiarity of repelling cold water, but warm water, from about q.0 ° C on, to be absorbed in increasing measure with the temperature, after which Dry again, as before, to repel cooler water.

Auf dieser überraschenden Beobachtung beruht das neue Verfahren, Fasergut, wie Papier, Pappe, Textilien u. dgl., gleichzeitig wasserabstoßend und feuerhemmend zu machen: Man verleiht dem Material zuerst durch milde Behandlung mit veresternd wirkenden Abkömmlingen höherer Fettsäuren wasserabstoßende Eigenschaften und tränkt es dann bei höherer, vorzugsweise über q.0° C: liegender Temperatur mit der für diesen Zweck auch sonst üblichen Salzlösung. Nach dem Trocknen erweist sich das Material als gleichzeitig feuerhemmend und abstoßend gegen Wasser von gewöhnlicher Temperatur. Beispiel i Man macht ein Jutegewebe wasserfest, indem man es mit einer Lösung von i °/" Stearylanhydrid tränkt, trocknet und 6 Stunden bei 8o° reifen läßt; sodann tränkt man das Gewebe bei mindestens 4o° -C mit einer Lösung, die i .5o g Chlorammonium,: 3o g Borax und 2o g Kochsalz im Liter enthält. Das so behandelte Gewebe wird getrocknet und ist gleichzeitig wasserabstoßend und feuerhemmend.The new process, fiber material, is based on this surprising observation. such as paper, cardboard, textiles, etc., at the same time water-repellent and fire-retardant to make: The material is first given esterifying by a mild treatment acting derivatives of higher fatty acids have water-repellent properties and soaks it then at a higher, preferably above q.0 ° C: lying temperature with that for this purpose also otherwise usual saline solution. After drying, that turns out to be Material as fire retardant and water repellent at the same time from ordinary Temperature. Example i A jute fabric is made waterproof by tying it with a Solution of 100% stearyl anhydride soaks, dries and matures for 6 hours at 80 °; the fabric is then soaked at at least 40 ° C. with a solution containing i .5o g Chlorammonium: contains 3o g borax and 2o g table salt per liter. Treated like that Fabric is dried and is at the same time water-repellent and fire-retardant.

Beispie12 Man stellt eine wasserfeste Pappe her, in= ; dem man dem im Holländer aufgeschlämmten - Papierstoff eine solche Menge einer 3°/oigen Emulsion von Stearvlänhvdrid in Wasser zusetzt, daß die Menge des Stearylanhydrids c °/o des trockenen Papierstoffes beträgt. Die auf diese Weise hergestellte Pappe wird getrocknet, C Stunden lang einer Temperatur von 9o° ausgesetzt und dann bei mindestens q.o° C mit einer Lösung getränkt, die im Liter roo g Chlorammonium und 5o g wolframsaures Natrium enthält. Die so behandelte Pappe wird getrocknet und ist gleichzeitig wasserabstoßend und feuerhemmend,Example12 A waterproof cardboard is made, in =; that one that slurried in the Dutch - Paper stock such an amount of a 3% emulsion of stearyl anhydride in water adds that amount of stearyl anhydride c ° / o of the dry stock. The cardboard made in this way is dried, exposed to a temperature of 90 ° C for hours and then at at least q.o ° C soaked in a solution containing roo g of chlorammonium per liter and Contains 50 g of sodium tungstate. The cardboard treated in this way is dried and is water-repellent and fire-retardant at the same time,
