Description

Pastenförmiges, Alkalibichromate und Teeröle enthaltendes Holzschutzmittel In der Holzschutztechnik sind Imprägniermittel in Pastenform bekannt, die Gemische aus Chrom-, Arsen-und Fluorsalzen sowie ein Quellmittel enthalten. Werden diese Gemische mit der entsprechenden Menge Wasser angerührt, so erhält man eine Paste, die dann auf entrindete, saftfrische oder feuchte Hölzer aufgetragen werden kann. Die Salze diffundieren in das Holz ein, und dabei finden die bekannten Umsetzungen der 6wertigen Chromsalze mit dem Holz statt, wobei sich dann die Reaktionen zwischen den entstehenden Chromiverb.indungen einerseits und den Arsenaten und Fluoriden andererseits anschließen und je nach dem pH-Wert schwer wasserlösliche Chromarsenate und Chromkryolithe entstehen; Stoffe, die ebenfalls eine stark fungicide Wirkung haben.Paste-form wood preservative containing alkali dichromates and tar oils In wood protection technology, impregnating agents in paste form are known, the mixtures made of chromium, arsenic and fluorine salts as well as a swelling agent. Will this Mixtures mixed with the appropriate amount of water result in a paste, which can then be applied to debarked, freshly juiced or damp wood. The salts diffuse into the wood, and this is where the known reactions take place the hexavalent chromium salts with the wood instead, whereby the reactions between the resulting chromium compounds on the one hand and the arsenates and fluorides on the other hand connect and, depending on the pH value, poorly water-soluble chromium arsenates and chrome cryolites arise; Substances that also have a strong fungicidal effect to have.

Gleichfalls sind Imprägnierpasten bekannt, die zusätzlich Öl enthalten oder vor der Verwendung mit diesem versetzt werden können. Diese 01-Salz-Pasten haben den Vorteil, daß die in ihnen gespeicherten Imprägniersalze langsamer gelöst werden und bei Einwirkung von Regenwasser diese besser gegen Auswaschung geschützt sind.Impregnation pastes are also known which additionally contain oil or can be added to it before use. These 01 salt pastes have the advantage that the impregnation salts stored in them dissolve more slowly and when exposed to rainwater they are better protected against leaching are.

Ebenso ist aber bekannt, daß die Verwendung solcher Holzschutzpasten, wenn sie Bichromate enthalten, dadurch in Frage gestellt wird, daß durch die Umsetzung des Bierornats mit den Teerölen die Pasten ihre streichförmige Konsistenz verlieren und damit unbrauchbar werden. So besteht bei diesen Konservierungsmitteln sogar die Gefahr, daß sich die Feststoffe in Form einer harten, zusammenhängenden Masse abscheiden.But it is also known that the use of such wood protection pastes, if they contain bichromates, this is called into question by the implementation of the beer garnish with the tar oils, the pastes lose their spreadable consistency and thus become unusable. So even with these preservatives the risk that the solids in the form of a hard, coherent mass deposit.

Überraschenderweise wurde nun gefunden, daß diese Nachteile durch einen Zusatz von Alkaliformiat, insbesondere Natriumformiat, zu den Teeröd-Bich.romat-Pasten nicht auftreten, sondern im Gegenteil diesen eine besonders gute Streichfähigkeit verleihen. Der Gebrauchswert solcher Pasten wird also in vorzüglicher Weise verbessert.Surprisingly, it has now been found that these disadvantages by an addition of alkali formate, especially sodium formate, to the Teeröd-Bich.romat pastes do not occur, on the contrary, they are particularly easy to spread to lend. The utility value of such pastes is thus improved in an excellent manner.

Es darf dagegen nicht unerwähnt bleiben, daß Natriumformiat das Unbrauchbarwerden von Buchenholzteeröl-Bichromat-Pasten nicht verhindert, aber überraschenderweise der Gebrauchswert von Steinkohlen- und Braunkohl.enteeröl-Bichromat-Pasten durch einen Natriumformiatzusatz wie beschrieben gehoben wird.It should not go unmentioned, however, that sodium formate is rendered useless not prevented by beechwood tar oil bichromate pastes, but surprisingly the practical value of hard coal and lignite tar oil bichromate pastes a sodium formate additive is raised as described.

Diesen mit Natriumformiat versetzten Teeröl-Bichromat-Pasten können erfindungsgemäß noch andere mykocid wirkende Stoffe, z. B. Quecksilbersalze, Zinksulfat u. dgl., zugesetzt werden. Durch die Verwendung von Quellmitteln, wie Tylose, Kaltleimen, Pflanzenschleimen od. dgl., können in oder ohne Anwesenheit von Emulgatoren mit Wasser und/oder Teeröl hergestellt werden, die keinerlei Feststoffe auch nach längerer Zeit ausscheiden. Das erfindungsgemäß zuzusetzende Allkaliformiat kann in einer Menge bis zu 25%, bezogen auf die Gesamtmischung, in der Paste vorhanden sein.These tar oil bichromate pastes mixed with sodium formate can according to the invention still other mycocidally acting substances such. B. mercury salts, zinc sulfate and the like, may be added. By using swelling agents such as Tylose, cold glue, Plant slimes or the like can be used in or without the presence of emulsifiers Water and / or tar oil are produced that contain no solids even after long periods of time Eliminate time. The alkali form to be added according to the invention can be used in a Amount of up to 25%, based on the total mixture, can be present in the paste.

Um die Erfindung noch näher zu erläutern, sei im folgenden als Beispiel die Zusammensetzung einer erfindungsgemäßen Paste angeführt. 15 Teile Natriumformiat 20 Kaliumbichromat 12 Natriumarsenat 12 Natriumfluorid 8 Emulgator 8 Quellmittel 25 ., Braunkohlenteeröl werden so lange miteinander verrührt, bis eine Paste entsteht.In order to explain the invention in more detail, the composition of a paste according to the invention is given below as an example. 15 parts of sodium formate 20 potassium dichromate 12 sodium arsenate 12 sodium fluoride 8 emulsifier 8 swelling agents 25., Lignite tar oil are mixed together until a paste is formed.

Diese streichfähige Paste kann mit Teeröl und/oder Wasser zu einer haltbaren und gleichmäßigen Emulsion verdünnt werden.This spreadable paste can be made with tar oil and / or water durable and even emulsion can be diluted.
