HOLZSCHUTZMITTELWOOD PROTECTIVE
Die Erfindung betrifft ein wasserlösliches Holzschutzmittel, bei dem die toxische Basis auf anorganischen Fluor-, Bor-, Kalium-, Natrium- oder Phosphorverbindungen beruht.The invention relates to a water-soluble wood preservative, in which the toxic base is based on inorganic fluorine, boron, Potassium, sodium or phosphorus compounds are based.
Der Einsatz der oben genannten anorganischen Verbindungen zur Herstellung der Holzschutzmittel ist an sich bekannt, insbesondere bei Fluor- und Borverbindungen.The use of the above-mentioned inorganic compounds for the production of wood preservatives is known per se, especially with fluorine and boron compounds.
Zu den im Holzschutz am meisten bekannten Fluorverbindungen gehören: Natriurnfluorid, Kaliumfluorid,, Zinkfluorsilikat, Kaiiumbifluorid, Ammoniumbifluorid und Ammoniumfluorborat. Die Fluorverbindungen wurden im Holzschutz getrennt (NaF) eingesetzt und bilden in der Regel weitere Bestandteile der herzustellenden Holzschutzmittel.The most well-known fluorine compounds in wood protection include: sodium fluoride, potassium fluoride, zinc fluorosilicate, Potassium bifluoride, ammonium bifluoride and ammonium fluoroborate. The fluorine compounds were used separately in wood protection (NaF) and usually form further components of the wood preservatives to be produced.
Die bekannten Holzschützmittel - Wolman-Salze - enthielten neben den Fluorverbindungen Chromsalze (U-Salze), Chrom- und Arsensalze (UA-Salze, Uli-Salze). Es werden auch Holzschutzmittel auf der Basis der Hydrofluoride hergestellt.The well-known wood preservatives - Wolman salts - contained in addition to the fluorine compounds, chromium salts (U salts), chromium and arsenic salts (UA salts, Uli salts). There are also wood preservatives made on the basis of hydrofluorides.
Die Holzschutzmittel - Bolidenn-Salze - im DL-P 54 100 beschriebene Wolmanit CB, Synpregnit CBZ, Soltex R-12 enthaltenThe wood preservatives - Bolidenn salts - described in DL-P 54 100 Wolmanit CB, Synpregnit CBZ, Soltex R-12 included
Borverbindungen. Die die Fluoride oder Hydrofluoride und Chromverbxndungen enthaltenden Holzschutzmittel hatten die Eigenschaft, .daß sie sich nach dem Imprägnieren im Holz fixierten, was auf Bildung von schwer im Wasser löslichen Verbindungen zurückzuführen ist. Ähnliche Eigenschaften hatten neben den genannten auch Holzschutzmittel, .die Borverbindungen enthielten. Die Ausbildung im Holz von im Wasser schwer löslichen Verbindungen unter Teilnahme von Chrom und Fluor bzw-. Chrom und Bor unmittelbar nach der Imprägnierung verhinderte ein weiteres Eindringen von Chrom in das Holz, und in seiner Anwesenheit auch von Fluor und Bor, sogar in Holz mit hohem Feuchtigkeitsgrad. Die Eindringtiefe dieser Mittel schwankt in den Grenzen von 2 bis 4 mm bei lufttrockenem Holz und von 4 bis 6 mm bei Holz mit höherem Feuchtigkeitsgrad, bei druckloser Imprägnierung.Boron compounds. Those the fluorides or hydrofluorides and Wood preservatives containing chromium compounds had the property that they fixed in the wood after impregnation, which is due to the formation of compounds that are difficult to dissolve in water. Had similar properties in addition to those mentioned, wood preservatives containing boron compounds. Training in wood from being difficult in water soluble compounds with the participation of chromium and fluorine respectively. Prevented chromium and boron immediately after impregnation further penetration of chromium into wood, and in its presence also fluorine and boron, even into wood with a high degree of moisture. The depth of penetration of these agents varies between 2 and 4 mm for air-dry wood and from 4 to 6 mm for wood with a higher degree of moisture, with pressureless impregnation.
Die auf Hydrofluoriden basierenden Holzschutzmittel (z.B. Improsol) drangen tatsächlich wesentlich tiefer in das Holz als die oben besprochenen Präparate und waren durch ihre Fähigkeit weiterer Penetration des Holzes nach der durchgeführten Imprägnierung gekennzeichnet. Jedoch scheidet das imprägnierte Holz bei der Alterung große Mengen an gasförmigem Fluorwasserstoff (^F2) aus, der sehr umweltschädlich ist. Im Ergebnis mußte das Holz nach der Imprägnierung ungefähr. 12 Wochen vor dem Einbau in das Gebäude gealtert werden.The wood preservatives based on hydrofluorides (e.g. Improsol) actually penetrated the wood much deeper than the preparations discussed above and were characterized by their ability to penetrate the wood further after the impregnation. However, the impregnated wood excretes large amounts of gaseous hydrogen fluoride (^ F 2 ), which is very harmful to the environment, as it ages. As a result, after the impregnation, the wood had to approx. To be aged 12 weeks before installation in the building.
Die wesentlichen Nachteile der Holzschutzmittel mit Gehalt an Chrom und Fluor bzw. Chrom und Bor bestanden in der kleinen Eindringungstiefe, keiner Fähigkeit zur Penetration in das Holz nach der Imprägnierung und zur dauerhaften Umfärbung des Holzes.The main disadvantages of wood preservatives with a content of chromium and fluorine or chromium and boron consisted of their small size Penetration depth, no ability to penetrate the wood after impregnation and no permanent color change of the wood.
Das erfindungsgemäße Holzschutzmittel ist durch große Eindringungstief e in das (lufttrockene und feuchte) Holz gekennzeichnet und bewirkt keine Farbveränderung des Holzes. Es ist sehr gut in Wasser löslich und geruchlos. Das erfindungsgemäße Mittel zeichnet sich durch seine FähigkeitThe wood preservative according to the invention is characterized by a large penetration depth e into the (air-dry and moist) wood and does not change the color of the wood. It is very soluble in water and has no odor. The inventive Medium is characterized by its ability
zur weiteren Penetration in das Holz nach der Imprägnierung durch Diffusion aus. Bei der Lagerung des Holzes unter Bedingungen, bei welchen eine Feuchtigkeitsveränderung des Holzes unmöglich ist, erhöht die Eindringungstiefe .des Mittels in das lufttrockene Holz sich um ca. 100 X1 in feuchtes Holz um über 100 %. Bei drucklosen Imprägnierungsverfahren und bei Ausnutzung der Diffusion kann beim Einsatz des erfindungsgemäßen Mittels eine Eindringungstiefe von über 20 mm erreicht werden. Das erfindungsgemäße Mittel .schützt Holz und Lignocellulosestoffe wirksam vor vernichtender Einwirkung von Mikroorganismen und ist gleichzeitig durch starke toxische Wirkung gegen Insekten und technische Holzschädlinge gekennzeichnet .for further penetration into the wood after impregnation by diffusion. When the wood is stored under conditions in which a change in the moisture content of the wood is impossible, the penetration depth of the agent in the air-dry wood increases by approx. 100 X 1 in moist wood by over 100%. In the case of pressureless impregnation processes and when using diffusion, a penetration depth of over 20 mm can be achieved when using the agent according to the invention. The agent according to the invention .protects wood and lignocellulosic substances effectively against the damaging effects of microorganisms and is at the same time characterized by a strong toxic effect against insects and technical wood pests.
Dank entsprechender Auswahl der chemischen Verbindungen und eng bestimmter Menge eines jeden Bestandteiles wurde aufgrund der durchgeführten Experimente ein hydrofluoridhaltiges Holzschutzmittel mit neutraler Einwirkung auf die Umwelt entwickelt. Thanks to the appropriate selection of chemical compounds and a tightly defined amount of each component, it was due of the experiments carried out a wood preservative containing hydrofluoride Developed with a neutral impact on the environment.
Die Beseitigung des grundsätzlichen Nachteils dieser Gruppe der Mittel - die Ausscheidung von gasförmigem Fluorwasserstoff an die Umwelt - bildet einen weiteren beträchtlichen Erfolg.Eliminating the fundamental disadvantage of this group of funds - the excretion of gaseous hydrogen fluoride to the environment - constitutes another significant achievement.
Das erfindungsgemäße Holzschutzmittel besteht aus fünf anorganischen Verbindungen: Kaliumbifluorid, zweibasischem Kaliumphosphat, Natriumtetraborat oder Orthoborsäure, Natriumoder Kaliumchlorid und Tensiden. In der genannten Zusammensetzung wurden diese Verbindungen bisher nicht als Holzschutzmittel eingesetzt.The wood preservative according to the invention consists of five inorganic ones Compounds: potassium bifluoride, dibasic potassium phosphate, Sodium tetraborate or orthoboric acid, sodium or potassium chloride and surfactants. In the composition mentioned these compounds have not yet been used as wood preservatives.
Die Einführung der Tenside aus der Estergruppe in das erfindungsgemäße Mittel ermöglicht eine Erhöhung der Eindinguhgstiefe in das Holz.The introduction of the surfactants from the ester group in the inventive Medium enables an increase in the depth of the binding in the wood.
Es wurde festgestellt, daß die besten Ergebnisse beim EinsatzIt has been found to give the best results when used
