Description

Konservierungsmittel für Holz Die vorliegende Erfindung bezieht sich auf ein schwer auslaugbares, wasserlösliches Konservierungsmittel für Holz, welches die Nachteile der bisher bekanntgewordenen Mittel nicht zeigt. Nach den bekannten Vorschlägen werden die schwer löslichen Konservierungsmittel im Holz selbst erzeugt, indem man das Holz entweder aufeinanderfolgend mit zwei Lösungen imprägniert, deren Bestandteile sich im Holz zu der schwer löslichen Verbindung umsetzen, oder es wird eine Lösung verwendet, aus der sich bei dem Eintrocknen im Holz die schwer löslichen Verbindungen bilden. Bei dem erstgenannten Verfahren hat man stets mit der Schwierigkeit zu kämpfen, daß die Umsetzung der beiden Lösungen unvollständig ist. Die bekannten Verfahren, die der zweiten Gruppe angehören, zeigen den Nachteil, daß die Lösungen nicht genügend beständig sind und sich insbesondere bei höherer Temperatur leicht zersetzen.Preservatives for Wood The present invention relates on a water-soluble preservative for wood that is difficult to leach, which does not show the disadvantages of the previously known means. According to the known Suggestions, the poorly soluble preservatives are produced in the wood itself, by impregnating the wood either successively with two solutions, whose Components in the wood convert to the poorly soluble compound, or it will a solution is used, from which the difficult to dissolve as it dries in the wood Form connections. In the first-mentioned method, one always has to deal with the difficulty to fight that the implementation of the two solutions is incomplete. The known Processes belonging to the second group have the disadvantage that the solutions are not sufficiently stable and easily move, especially at higher temperatures decompose.

Es ist nün gefunden worden,, daß man ein in Wasser genügend lösliches und auch bei höheren Temperaturen eine beständige Lösung lieferndes, fungizid stark wirksames und schwer auslaufbares Konservierungsmittel für Holz aus 45 Teilen Kali_umbichromat, ._o__'-ei-.. len Fluornatrium und-#-Teilen_Dinitrophenol__ Aeryält - Diesem Gemisch lcönnen in an sich bekannter Weise Stoffe, die die Entflammbarkeit des Holzes herabsetzen, zugesetzt werden. Man vermischt also 45 Teile Kaliumbichromat, 5o Teile Fluornatrium und 5 Teile Dinitrophenol und verwendet dieses Salzgemisch in an sich bekannter Weise zum Tränken von Holz in einer 1,8 % igen Lösung.It has now been found that a preservative for wood that is sufficiently soluble in water and provides a stable solution even at higher temperatures, has a fungicidal effect and is difficult to leak, is made from 45 parts of potassium umbichromate, ._o __'- a few fluorosodium and # -Teilen_Dinitrophenol__ Aeryält - This mixture can be added to substances that reduce the flammability of the wood in a manner known per se. 45 parts of potassium dichromate, 50 parts of fluorosodium and 5 parts of dinitrophenol are therefore mixed and this salt mixture is used in a manner known per se to soak wood in a 1.8% solution.

Die Verwendung des neuen Konservierungsmittels zum Imprägnieren von Holz kann in jeder geeigneten Weise erfolgen, z. B. durch Tränken in geschlossenen Kesseln unter Anwendung von Vakuum und Druck, durch Einlagern in die Imprägnierflüssigkeit in offenen Trögen, durch Anstreichen nach dem Bandageverfahren, nach dem sogenannten Impfverfahren usw. Vor der Imprägnierung kann eine geeignete Vorbehandlung des Holzes stattfinden, indem man es z. B. in an sich bekannter Weise einer Behandlung mit Heißluft oder Dampf unterwirft. Man kann auch die wässerigen Lösungen der neuen Imprägniermittel im Gemisch mit öligen Flüssigkeiten, z. B. als Emulsionen, benutzen oder zur Doppeftränkung verwenden, indem man das Holz zuerst mit der wässerigen Lösung und dann mit einer öligen Flüssigkeit tränkt, oder umgekehrt.The use of the new preservative to impregnate Wood can be made in any suitable manner, e.g. B. by soaking in closed Kettles using vacuum and pressure, by embedding in the impregnation liquid in open troughs, by painting according to the bandage method, according to the so-called Vaccination process, etc. Before impregnation can be a suitable pretreatment of the wood take place by z. B. in a known manner with a treatment Subjects to hot air or steam. One can also use the aqueous solutions of the new Impregnating agent mixed with oily liquids, e.g. B. as emulsions or use for double soaking by first washing the wood with the watery one Solution and then soak with an oily liquid, or vice versa.

Der Vorteil des neuen Holzkonservierungsmittels besteht vor allem in der überraschend großen Widerstandsfähigkeit gegen Austaugung. Die größte Schwierigkeit, mit der man SeiZer Konservierung des Holzes mit wasserlöslichen Schutzstoffen immer wieder zu kämpfen hatte, besteht in der zu leichten Auslaugbarkeit dieser Stoffe, und dieser Nachteil aus dem Holz, das z. B; in bekannter Weise mit der Lösung eines Salzgemisches aus 85 Teilen Fluornatrium, io Teilen Dinftrophenol und Teilen Kaliumbichromät imprägniert w r e, das Fluornatrium durch Wasser von gewöhnlicher Temperatur bis zu etwa 87 % ausgelaugt wird, zeigen Hölzer, die mit einer wässerigen Lösung des beanspruchten Konservierungsmittels unter sonst gleichen Umständen imprägniert un ausgelaugt wurden, daß aus ihnen nur'etwa 47'/" ed Fluors durch asser ausgewasc @i` werden.The main advantage of the new wood preservative is its surprisingly high resistance to leaching. The greatest difficulty that SeiZer has had to struggle with over and over again for the preservation of wood with water-soluble protective substances is that these substances are too easy to leach, and this disadvantage from the wood that z. B; If the solution of a salt mixture of 85 parts of fluorosodium, 10 parts of dinftrophenol and parts of potassium bichromate were impregnated in a known manner, the fluorosodium is leached by water at a normal temperature of up to about 87 % is shown by woods that have been treated with an aqueous solution of the claimed preservative, among other things impregnated and leached in the same circumstances, so that only 'about 47' / "ed fluors are washed out from them by water.

Es ist bereits vorgeschlagen worden, in Imprägnierflüssigkeiten für Holz, die Dinitrophenole oder Dinitrophenolsalze gegebenenfalls im Gemisch mit anorganischen Schutzstoffen, z. B. Fluornatrium, enthalten, als Schutzmittel für die eisernen Imprägnierungsapparate Chromate oder Bichromate der Alkalien in einer io°% der Trockensubstanz der Imprägnierlösung nicht übersteigenden Menge zu verwenden. Es ist ferner vorgeschlagen Bichrornate als Schutzmittel für das Eisen, und man wußte; daß bereits ein Zusatz in der Menge von io°/o der Trockensubstanz unbedingt ausreicht, um die gewünschte Wirkung des Eisenschützes zu erreichen. Im Gegensatz zu diesen bekannten Vorschlägen verwendet man das Kaliumbichromat in einer Menge von 45 °/o, da man nur durch die Anwendung dieser erheblichen Menge eine Bindung des Fluors an die Holzfaser in dem in der Praxis erwünschten Grad erreicht.It has already been proposed, in impregnation liquids for wood, the dinitrophenols or dinitrophenol salts, optionally in a mixture with inorganic protective substances, eg. B. fluorosodium, to use as a protective agent for the iron impregnation apparatus chromates or bichromates of the alkalis in an amount not exceeding 10% of the dry substance of the impregnation solution. It is also suggested Bichrornate as a protective agent for iron, and it was known; that an addition in the amount of 10 per cent of the dry substance is absolutely sufficient to achieve the desired effect of the iron protection. In contrast to these known proposals, the potassium dichromate is used in an amount of 45%, since only by using this considerable amount can the fluorine be bound to the wood fiber to the degree desired in practice.
