Description

Verfahren zur Vergütung von mit Imprägnierölen getränktem Holz Beim Imprägnieren von Holzteilen aller Art, wie Pfosten, Masten, Schwellen, Bretter u. dgl., mit Imprägnierölen, insbesondere aus Steinkohlen- oder Braunkohlenteeren, kann beobachtet werden, daß das Verharzen des Imprägnieröles an der Luft einige Zeit in Anspruch nimmt. Das getränkte Material muß längere Zeit gelagert werden. da bei Hölzern, die zum Nachschwitzen neigen, die Außenflächen schmierig und klebrig werden. Es ist vorgeschlagen worden, teerölgetränkte Hölzer durch Bestreichen mit konzentrierter Salpetersäure oder auch Alkalilösung nachzubehandeln (vgl. B o d m a r-T i 1:g e r, Die Konservierung des Holzes, 1922, S. 783), um den Geruch zum Teil zu beseitigen. Doch haben sich diese Verfahren in der Praxis nicht einführen lassen.Process for the compensation of wood soaked with impregnating oils Impregnation of wooden parts of all kinds, such as posts, masts, sleepers, boards and the like. Like., with impregnating oils, especially from coal or lignite tars, It can be observed that the impregnating oil gummifies in air some Takes time. The soaked material must be stored for a long time. because with woods that tend to sweat afterwards, the outer surfaces are greasy and sticky will. It has been suggested that wood soaked in tar oil can be coated with concentrated nitric acid or alkali solution (see B o d m a r-T i 1: g e r, The Preservation of Wood, 1922, p. 783) to the smell to Eliminate part. However, these procedures have not been implemented in practice permit.

Es wurde nun gefunden, daß man die Polymerisation der Imprägnieröle mit Hilfe von gasförmigen oder leicht in den gasförmigen Zustand überführbaren, polymerisierend wirkenden Mitteln so beschleunigen kann, daß die Verharzung der imprägnierten Hölzer in wirtschaftlicher Weise und unter geringem Zeitaufwand möglich ist. Solche Mittel sind insbesondere anorganische und auch organische Verbindungen des Chlors und Fluors, die bereits bei gewöhnlicher oder auch bei technisch leicht erreichbaren höheren Temperaturen, etwas um 100° C, eine Polymerisation der Ölbestandteile bewirken.It has now been found that the polymerization of the impregnating oils with the help of gaseous or easily convertible into the gaseous state, polymerizing agents can accelerate so that the resinification of the impregnated wood can be done economically and with little expenditure of time is. Such agents are in particular inorganic and also organic compounds of chlorine and fluorine, which are already common or technically easy achievable higher temperatures, something around 100 ° C, a polymerization of the oil components cause.

Zur analytischen Überprüfung wurden Holzklötzchen der Größe 50 - 25 - 15 mm, jeweils 10 Stück, bei 105° C 1 Stunde mit Imprägnieröl getränkt. Die Klötzchen blieben nach wochenlangem Liegen an der Luft noch fettig und ölig. Überführt man dagegen in einem zweiten Versuch die Holzklötzchen nach dem Tränken in einen Raum, der mit gasförmigem Bortrifluorid gefüllt ist. so beobachtet man, daß fast augenblicklich eine Verharzung des Öles erfolgt, was sich durch Schwarzfärbung der vorher bräunlichen Holzklötzchen zu erkennen gibt. Die aus dem Raum nach etwa 20 Minuten Einwirkungsdauer entnommenen Holzstücke läßt man zwecks Vervollständigung der Verharzung noch einen Tag an der Luft liegen; sie fühlen sich sodann völlig trocken an und geben, auf Filtrierpapier gebracht, keinen Ölfleck.For the analytical check, wooden blocks of size 50 - 25 - 15 mm, 10 pieces each, soaked in impregnating oil for 1 hour at 105 ° C. The blocks remained greasy and oily after lying in the air for weeks. Convict on the other hand in a second attempt the wooden blocks after soaking in a room, which is filled with gaseous boron trifluoride. so one observes that almost instantly the oil becomes resinified, which is reflected in the previously brownish color There are wooden blocks to be recognized. The one out of the room after about 20 minutes of exposure removed pieces of wood are left to complete the resinification Day lying in the air; they then feel completely dry and give up Brought filter paper, no oil stain.

Der gleiche Effekt wird erzielt, wenn man die Tränkung der Hölzer im Autoklav nach dem bekannten Rüping-Verfahren oder auf andere Weise f)ewirkt. An Stelle von Bortrifluorid läßt sich mit gleichem Erfolg Thionylchlorid benutzen; zur Vermeidung einer Kondensation des Chlorids wird hierbei der Nachbehandlungsraum auf etwa 100° C erwärmt; die Verharzung ist innerhalb 15 Minuten vollständig.The same effect is achieved if you impregnate the wood in the autoclave according to the known Rüping process or in some other way f) e. Instead of boron trifluoride, thionyl chloride can be used with equal success; the post-treatment room is used to avoid condensation of the chloride heated to about 100 ° C; resinification is complete within 15 minutes.

Ferner lassen sich z. B. Chlorwasserstoffgas oder 11T 02-Gas, wobei letzteres mit Inertgas verdünnt werden kann, verwenden. Die verharzende Wirkung der genannten Stoffe tritt - wie erwähnt - fast augenblicklich ein, und es genügen dazu die in Gasform vorhandenen geringen Mengen, die somit wahrscheinlich eine praktisch nur katalytische Wirkung ausüben. Hierin unterscheidet sich das erfindungsgemäße Verfahren grundsätzlich von bekannten Umsetzungen, bei denen z. B. durch Sättigen mit halogenhaltigen Gasen (französische Patentschrift 670 766), durch Einwirkung von größeren Mengen Chlor (deutsche Patentschriften 567 100; 406 689, USA.-Patentschrift 2 059 051), eine Härtung von Mineralölen, wie Straßenteer oder Pechen, erreicht werden soll.Furthermore, z. B. hydrogen chloride gas or 11T 02 gas, where the latter can be diluted with inert gas, use. The resinifying effect of the substances mentioned occurs - as mentioned - almost instantly, and it is sufficient in addition, the small quantities present in gaseous form, which are thus probably a practical only have a catalytic effect. This differs from the one according to the invention Method basically of known implementations in which z. B. by saturation with halogen-containing gases (French patent 670 766), by action of larger amounts of chlorine (German patents 567 100; 406 689, USA.-Patent 2 059 051), a hardening of mineral oils, such as road tar or pitch, is achieved shall be.
