Definitions

• the invention relates to non-aqueous wood preservatives based on biocidal quaternary ammonium compounds and carboxylic acids as well as their use for the treatment of dry or dried wood and the wood treated in this way that can be treated with protection.
• Quaternary ammonium compounds have been known as effective bactericides and fungicides in the fields of pharmacy, disinfection and preservation and have been used extensively since the 1930s. The broad spectrum of effectiveness is also used in material protection, especially in the field of wood preservation. Due to the high water solubility of the quaternary ammonium compounds, they are found almost exclusively in water-based preparations, alone or in combination with other active ingredients, e.g. B. copper compounds, in the so-called ACQ salts. Due to the ionic character quaternary ammonium compounds are in non-polar solvents such as. B. White spirit, petroleum or white spirit is only slightly or not soluble.
• Preparations based on the mineral oil derivatives mentioned are of great importance in wood preservation, especially if dry woods with high demands on dimensional accuracy have to be subjected to a protective treatment.
• woods are, for example, glued timber (glued laminated girders), doors, windows, construction timber (prefabricated houses) and similar.
• quaternary ammonium compounds have so far not been able to be used economically, since sufficient solubility of quaternary ammonium compounds, for example in white spirit (bp. 180-220 ° C.), could only be achieved by means of large amounts of solubilizers or emulsifiers.
• Such additives have a considerable influence on the properties of the preparations, e.g. B. water absorption or leachability when using emulsifiers.
• the paintability and aging behavior of the treated surfaces can also be adversely affected.
• the object of the present invention was therefore to provide wood preservatives based on quaternary ammonium salts which contain non-polar solvents such as white spirit without large amounts of added solubilizers or emulsifiers and thus also with mechanically finished wood without any adverse effects dimensional stability, surface quality, paintability and environmental compatibility.
• the object is achieved by the wood preservatives according to claim 1.
• the wood preservatives according to the invention contain 0.5 to 50 parts by weight of a biocidal quaternary ammonium compound or a mixture of such compounds and 0.5 to 50 parts of an aliphatic or cycloaliphatic carboxylic acid having 6 to 30 carbon atoms or a mixture of such carboxylic acids, with the proviso that that the ratio of quaternary ammonium compound and carboxylic acid is in the range of 1: 3 to 3: 1, and 10 to 99 parts of a non-polar organic solvent.
• they can optionally contain other additives, namely in particular
• biocidal substances such as fungicides, insecticides, molluscicides or bactericides,
• biocidal quaternary ammonium compounds are preferably those of the general formula
• R 1 is benzyl or Ce_ 18 alkyl
• R 2 d-ig alkyl or - [(CH 2 ) 2 -O] "R 5 with n 1-20
• R 3 and R 4 independently of one another C ⁇ _ 4 alkyl
• R 5 is hydrogen or optionally substituted phenyl
• a ⁇ is a monovalent anion or an equivalent of a polyvalent anion of an inorganic or organic acid.
• Alkyl here and in the following is to be understood in each case to mean linear or branched alkyl groups of the stated carbon numbers, but preferably linear alkyl groups and particularly preferably those with an even number of carbon atoms. In particular, this also includes the homolog mixtures derived from natural raw materials, such as, for example, “coconut alkyl”.
• Substituted phenyl is to be understood in particular to mean phenyl groups which are substituted by one or more C 8 alkyl groups and / or by one or more chlorine atoms.
• inorganic or organic anions in particular halide such as chloride or bromide, borate or anions of lower carboxylic acids such as acetate, propionate or lactate, are in principle suitable as anion A ⁇ .

• Saturated or unsaturated natural or synthetic fatty acids are preferred as aliphatic or cycloaliphatic carboxylic acids having 6 to 30 carbon atoms or the cycloaliphatic carboxylic acids known as “naphthenic acids” and mixtures of such carboxylic acids.
• these include, in particular, the fatty acids and fatty acid mixtures obtainable from natural fats and fatty oils, such as, for example, coconut, linseed oil and soy fatty acids.
• Aliphatic or cycloaliphatic hydrocarbons or mixtures thereof are preferably used as non-polar organic solvents. These include, for example, the high-boiling hydrocarbon fractions commercially available under the names varnish, heavy or white spirit and products such as "White Spirit", petroleum and decalin.
• Heavy mineral oils can also be used as solvents for outdoor applications.
• the wood preservatives according to the invention penetrate quickly and deeply into the wood to be treated; the dimensions and surface structure remain unchanged.
• they are characterized by the fact that the salt-like quaternary ammonium compounds cannot evaporate from the substrate because of their non-volatility and therefore there is no need to worry about any loss of activity or environmental damage caused by the emitted active ingredient.
• the wood preservatives according to the invention can be used for all treatment methods customary in wood protection, such as painting, spraying, dipping and (pressure) impregnation. They are preferably used to treat dry wood by brushing, dipping or impregnation.
• agents according to the invention is not limited to woods, they are equally suitable for the preservation of other porous organic substrates such as paper, cardboard, cork and the like.
• the invention likewise relates to the woods which have been treated by treatment with the wood preservatives according to the invention and are treated with biocidal quaternary ammonium compounds with the addition of aliphatic or cycloaliphatic carboxylic acids having 6 to 30 carbon atoms or a mixture of such carboxylic acids.
