Description

Holzkonservierungsmittel. Die vorliegende Erfindung betrifft ein neues Holzkonservierungsmittel, welches geeignet ist, das Holz gegen die Angriffe von holzzerstörenden Pilzen und Tieren dauernd zu schützen. Die Erfindung beruht auf der Beobachtung, daß das in der nachstehend ang - e gebenen Weise zusammengesetzte Holzkonservierungsmittel eine viel größere antiseptische Wirkung aufweist, als die Summenwirkung der einzelnen für den gleichen Zweck bereits benutzten Bestandteile es erwarten läßt. Das neue Holzkonservierungsmittel besteht aus nitrierten Kresolen, Fluorverbindungen, Arsenverbindungen und schließlich aus solchen Stoffen, welche den Angriff des Eisens durch die Lösungen des Konservierungsmittels verhindern. Es hat sich gezeigt, daß in einem derart zusammengesetzten Holzkonservierungsmittel die konservierenden Eigenschaften der einzelnen Bestandteile sich nicht einfach addieren, sondern daß die Wirkung des in der beschriebenen Weise zusammengesetzten Konservierungsmittels bedeutend höher ist als die Summenwirkung der einzelnen Bestandteile. Das Mittel ist imstande, die mit ihm behandelten Hölzer sowohl gegen den Angriff von holzzerstörenden Pilzen als auch gegen den Angriff von Tieren, namentlich Insekten, zu schützen. Es ist aus dem Holz schwer auslaugbar, chemisch nicht 'leicht veränderlich und kann nach jedem beliebigen Verfahren und in jeder beliebigen Apparatur zur Tränkung von Holz verwendet werden. Als nitrierte Kresole kann man z. B. Mononitrokresole oder Dinitrokresole verwenden. Gute Erfolge haben auch die Verbindungen der nitrierten Kresole mit organischen Basen, z. B. mit Anilin oder Pyridin, gezeigt. Als Fluorverbindungen kann man jedes beständige, wasserlösliche Fluorsalz, z. B. Kieselfluornatrium oder Fluornatrium, verwenden. Als Arsenverbindungen verwendet man zweckmäßig Salze, die chemisch beständig sind und eine hohe Giftwirkung gegen Pilze und Tiere aufweisen; z. B. verwendet man die Arsensäure oder deren Salze. Als Eisenschutzmittel kann man z. B. chromsaure oder bichromsaure Alkalien verwenden. Beispiel. Man mischt ro Teile o-Dinitrokresol, qo Teile Fluornatrium, 3o Teile Natriumarseniat und 2o Teile N atriumbichromat miteinander. Dieses Salzgemisch kann zweckmäßig in 2prozentiger wässeriger Lösung zur Imprägnierung von Holz verwendet werden.Wood preservatives. The present invention relates to a new wood preservative which is suitable for permanently protecting the wood against attacks by wood-destroying fungi and animals. The invention is based on the observation that in the HS below - e discontinued manner composite wood preservative has a much larger antiseptic effect than the sum of the individual effects for the same purpose already used ingredients can it be expected. The new wood preservative consists of nitrated cresols, fluorine compounds, arsenic compounds and finally substances that prevent the iron from attacking by the preservative solutions. It has been shown that in a wood preservative composed in this way, the preservative properties of the individual components do not simply add up, but that the effect of the preservative composed in the manner described is significantly higher than the cumulative effect of the individual components. The agent is able to protect the wood treated with it both against attack by wood-destroying fungi and against attack by animals, namely insects. It is difficult to leach out of the wood, is not easily chemically changed and can be used for impregnating wood by any desired method and in any desired apparatus. As nitrated cresols you can z. B. use mononitrocresols or dinitrocresols. The compounds of nitrated cresols with organic bases, e.g. B. with aniline or pyridine shown. The fluorine compounds can be any stable, water-soluble fluorine salt, e.g. B. silica fluorosodium or fluorosodium use. The arsenic compounds used are appropriately salts which are chemically stable and have a high poisonous effect against fungi and animals; z. B. arsenic acid or its salts are used. As an iron protectant you can, for. B. use chromic or bichromic alkalis. Example. Ro parts of o-dinitrocresol, qo parts of fluorosodium, 30 parts of sodium arsenate and 20 parts of sodium bichromate are mixed with one another. This salt mixture can expediently be used in a 2 percent aqueous solution to impregnate wood.

Man kann- das neue Holzkonservierungsmittel im Gemisch mit anderen antiseptisch wirkenden oder die Entflammbarkeit des Holzes herabsetzenden Verbindungen verwenden. Die Tränkung des Holzes mit den Lösungen des Konservierungsmittels kann in jeder beliebigen Weise, z. B. in offenen Trögen aus Holz oder Zement oder in eisernen Kesseln unter Anwendung von Vakuum und Druck oder durch Anstreichen usw., erfolgen.You can use the new wood preservative mixed with others antiseptic compounds or compounds that reduce the flammability of the wood use. The impregnation of the wood with the solutions of the preservative can in any way, e.g. B. in open troughs made of wood or cement or in iron kettles using vacuum and pressure or painting, etc., take place.
