KoDrawing. Application filed liovemberfi, 1923, tierlal No. 673,850, and in Germany September 26, 1923.
My invention relates to anew and improved wood preserving composition which is suited to protect permanently the wood from the attacks of wood-destroying fungi and animals. The invention is based on the observation that the wood preserving composition disclosed in' the following lines possesses a by far greater antiseptic effect than it could be expected according to. the efiect of the unmixed components of which said composition consists. The new Wood preserving means consists principally of nitratedf'cresols, fluorine compounds and arsenic compounds which are soluble in 'water finally, of such substances which are apt to protect iron from being afiected by solutions of the said wood preserving means.
It has been found that in a thus composed wood preserving composition the preserving properties of the individual component substances do not simply sum up but that the effect of thepreserving means composed in the manner hereinafter described isconsiderably greater than the summed effect of the individual unmixed substances composing it. The preserving composition in question is able to protect the wood treated therewith from the attack of wood-destroying fungi, as well asfrom the attack of animals, especially insects. It is very difiicult to lixiviate it out of the wood, it is chemically not easily changeable and may be used for-the impregnation ofthe wood in any desired manner and with any desired apparatus. 1
The nitrated cresols may be mononitrocresols or dinitro-cresols. Also the compounds :of the nitrated cresols wit organic bases have delivered good results. As fiuorine compound every stable, water-soluble floor-salt, for instance sodium silicofluoride or fluoride of sodium, may be used." As arsenic compounds'preferably salts are used and apt to counteractthe action of fungi, ind,
vof sodium, are mixed. with each other. This mixture is, preferably, dissolved in Water, in such a proportion that a 2%-solution is obtained, which is used for impregnating the wood. i i
The new wood preserving composition may be used in connection with other compounds 1 of antiseptic effect or those adapted to di minish the inflammability of the Wood. Impregnating the wood therewith maybe effected in any desired'manner, for instance in open wooden troughs, or in trou hs of ce- 'ment, or in iron containers, may je in connection either with reduced or 'increased pressure, or by boiling the wood in the respective solution, and so on.
Concerning the addition of an iron-pro-.. tective' means I point out that this addition 79 is necessary from the reason as otherwise the iron receptacles, troughs, or the like, in which the wood'is impregnated would be affected by 1 the wood preserving composition introduced into said receptacles, etc, This is true espe-' cially' of the nitrated phenols and the salts thereof whichhavethe property ofafiecting Thus, fOI iIl- 45
