Verfahren zur Behandlung von Holz und Verwendung eines wasserbindenden MittelsMethod for treating wood and using a water-binding agent
Die Erfindung betrifft ein Verfahren zur Behandlung von Holz, insbesondere Holzrahmen, bei dem ein Konservierungsmittel in flüssiger oder pastenartiger Form in eine im Holz angebrachte Aussparung oder einen Hohlraum eingebracht und dieser Hohlraum anschließend dicht verschlossen wird, und die Verwendung eines wasserbindenden Mittels zum Konservieren von Holz.The invention relates to a method for treating wood, in particular wooden frames, in which a preservative in liquid or paste-like form in a recess made in the wood or a cavity is introduced and this cavity is then sealed, and the use a water-binding agent for preserving wood.
Aus der DE-AS 28 12 697 ist ein Verfahren zur Holzbehandlung bekannt, bei dem ein wasserabstoßendes MiLLeI in Verbi.mlurni mil ο I nom waKüorvorlrcibiMiili'H Mittel in einen im Holz angebrachten Hohlraum eingebracht wird und dieser Hohlraum anschließend dicht verschlossen wird. Dieses bekannte Verfahren hat den Nachteil, daß die Diffusion von Wasser in Holz stark behindert ist und daher nur sehr langsam abläuft. Insbesondere bei Holz, das mit einer Beschichtung, z.B. in Form einer Lackierung oder Kunststoffbeschichtung, versehen ist, ist der Austritt des Wassers aus dem Holz sehr stark behindert bzw. unter Umständen ganz ausgeschlossen. Bei der Altbausanierung stellt sich häufig das Problem, daß Fensterrahmen in ihrem unteren Drittel eine erhöh l.o Pouch Lo aufweiten, die in Zufcammenwlrkuncj mil M i kroortjun i :-»iiumi .ml clic* Imwci x.u einer vollständigen Zerstörung des Holzes führt.From DE-AS 28 12 697 a method for treating wood is known in which a water-repellent MiLLeI in Verbi.mlurni mil ο I nom waKüorvorlrcibiMiili'H Means is introduced into a cavity made in the wood and this cavity is then tightly closed will. This known method has the disadvantage that the diffusion of water in wood is strong is disabled and therefore runs very slowly. In particular with wood covered with a coating, e.g. in the form of a paint or plastic coating, is the leakage of the water from the Wood is severely hindered or, under certain circumstances, completely excluded. The renovation of old buildings arises often the problem that window frames in their lower third widen an increased pouch lo, which in Zufcammenwlrkuncj mil M i kroortjun i: - »iiumi .ml clic * Imwci x.u leads to complete destruction of the wood.

Es ist Aufgabe der Erfindung, diese Nachteile des Standes der Technik zu vermeiden und ein Verfahren zur Behandlung von Holz zu schaffen, das eine schnelle Herabsetzung der Holzfeuchte ermöglicht. Das Verfahren soll insbesondere bei beschichtetem Holz, z.B. mit einem Anstrich versehenen Fensterrahmen, gute Ergebnisse liefern.It is the object of the invention to avoid these disadvantages of the prior art and to provide a method for treating wood that enables the wood moisture to be reduced quickly. The procedure should give good results, especially with coated wood, e.g. window frames that have been painted deliver.
Diese Aufgabe wird bei einem Verfahren der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß eine Lösung eines wasserbindenden Mittels in einem organischen Lösungsmittel in den Hohlraum eingebracht wird.In a method of the type mentioned at the outset, this object is achieved according to the invention in that a solution of a water-binding agent in an organic solvent is introduced into the cavity will.
Vorteilhaft wird eine Lösung eines Orthocarbonsäureesters verwendet. Geeignete Verbindungen sind z.B. Trimethylorthoformiat, Trimethylorthoessigsaureester, Triethylorthoessigsäureester und entsprechende Ester der Orthopropionsäure. Besonders bevorzugt wird jedoch eine Lösung von Triethylorthoformiat, die vorteilhaft eine Konzentration von 10-40 Gew.-% aufweist.A solution of an orthocarboxylic acid ester is advantageously used. Suitable compounds are e.g. Trimethyl orthoformate, trimethyl orthoacetic acid ester, triethyl orthoacetic acid ester and corresponding esters of orthopropionic acid. However, it is particularly preferred a solution of triethyl orthoformate, which advantageously has a concentration of 10-40% by weight.
Eine besonders gute Konservierung von Holz wird dadurch erreicht, daß die Lösung neben dem wasserbindenden Mittel fungizide, bakterizide und/oder insektizide Wirkstoffe enthält. Die Lösung kann z.B. Tributylzinnoxid in einer Konzentration von 1-10 Gew.-% und/oder N-Dimethyl-N'-pheny1-N'-(fluordichlormethy1) -thiosulfamid in einer Konzentration von 0,5 - 40 Gew.-% enthalten.A particularly good preservation of wood is achieved that the solution in addition to the water-binding Agent contains fungicidal, bactericidal and / or insecticidal active ingredients. The solution can, for example, be tributyl tin oxide in a concentration of 1-10% by weight and / or N-dimethyl-N'-pheny1-N '- (fluorodichloromethy1) thiosulfamide in a concentration of 0.5 - 40% by weight contain.

Zur Verbesserung der konservierenden Wirkung kann die Lösung ein natürliches oder synthetisches Wachs in einer Konzentration von 2-20 Gew.-% enthalten. Dieses Wachs verhindert das weitere Eindringen von Feuchtigkeit in das Holz und unterstützt so die Wirkung des wasserbindenden Mittels. Geeignet ist z.B. ein Polyethylenwachs mit einem mittleren Molekulargewicht von ca 2000. Es können auch Paraffine mit einem Schmelzbereich von ca 700C eingesetzt werden.To improve the preservative effect, the solution can contain a natural or synthetic wax in a concentration of 2-20% by weight. This wax prevents the further penetration of moisture into the wood and thus supports the effect of the water-binding agent. For example, a polyethylene wax with an average molecular weight of approx. 2000 is suitable. Paraffins with a melting range of approx. 70 ° C. can also be used.
Das erfindungsgemäße Verfahren wird vorteilhaft so durchgeführt, daß das Konservierungsmittel in schräg nach unten gerichtete Bohrlöcher eingebracht wird und diese Bohrlöcher anschließend mit einer Holzfüllmasse verschlossen werden. Die Bohrlöcher werden vorteilhaft mit einer durch Härterzusatz aushärtenden Holzfüllmasse verschlossen. Derartige Massen sind als sogenannte "Zweikomponenten-Holzfüllmassen" bekannt. Nach dem Verschließen der Bohrlöcher und dem Aushärten der Verschlußmasse kann die behandelte Stelle mit einem Anstrich versehen werden, so daß die Konservierungsmaßnahme keine sichtbaren Spuren hinterläßt.The inventive method is advantageously carried out so that the preservative in oblique downwardly directed boreholes is introduced and these boreholes then with a wood filler be locked. The drill holes are advantageously made with a hardening agent that hardens Wood filler closed. Such masses are known as so-called "two-component wood filling masses". After the boreholes have been sealed and the sealing compound has hardened, the treated Place to be painted so that the preservation measure does not have any visible traces leaves behind.
Die Erfindung betrifft weiterhin die Verwendung eines wasserbindenden Mittels zum Konservieren von Holz. Überraschenderweise hat sich gezeigt, daß die Bindung des im Holz vorhandenen Wassers gegenüber einer Vertreibung erhebliche Vorteile aufweist.The invention also relates to the use of a water-binding agent for preserving wood. Surprisingly, it has been shown that the binding of the water present in the wood compared to a Eviction has significant benefits.

Nach 2 Wochen wurde der Feuchtigkeitsgehalt erneut bestimmt. Er war auf einen Wert von etwa 20 % abgesunken. Bei diesem Peuchtegehalt ist z.B. ein Schimmelwachstum ausgeschlossen. Darüberhinaus war eine deutliche Verfestigung des behandelten Holzes festzustellen, die sich darin äußerte, daß zum Eindrücken eines harten Gegenstandes in das Holz ein größerer Kraftaufwand als vorher erforderlich war.The moisture content was determined again after 2 weeks. He was at a value of dropped about 20%. With this moisture content, for example, mold growth is excluded. In addition, a clear solidification of the treated wood was to be determined, which in it said that a greater amount of force was required to press a hard object into the wood than was previously required.
