Abstract

The invention pertains to heavy metal-free wood preservatives that contain polymeric quaternary ammonium borate and (4-ethoxyphenyl) (3-(fluoro-3-phenoxyphenyl)propyl-(dimethyl)silane.

Description

Vorbeugende HolzschutzmittelPreventive wood preservatives
Die Erfindung betrifft schwermetallfreie vorbeugende Holzschutzmittel mit guter fungizider Wirkung.The invention relates to preventive wood preservatives which are free of heavy metals and have a good fungicidal action.
Aus EP-A 0 355 316 ist bekannt, polymere quartare Am¬ moniumborate als fungizid wirkende Holzschutzmittel mit guter Eindringtiefe einzusetzen.It is known from EP-A 0 355 316 to use polymeric quaternary ammonium borates as fungicidal wood preservatives with good penetration depth.
Gemäß EP-A 0 498 162 haben diese polymeren quartären Ammoniumborate auch eine insektizide Wirkung. Jedoch werden relativ große Einbringmengen des Wirkstoffs ge¬ braucht, um einen ausreichenden Schutz des Holzes gegen Insekten zu erzielen. Außerdem waschen Borsalze langsam aus, so daß sich die fungizide und die insektizide Wir¬ kung bei längerer Gebrauchsdauer verliert, wenn das damit imprägnierte Holz der Bewitterung ausgesetzt ist.According to EP-A 0 498 162, these polymeric quaternary ammonium borates also have an insecticidal action. However, relatively large amounts of the active ingredient are required in order to achieve adequate protection of the wood against insects. In addition, boron salts wash out slowly, so that the fungicidal and the insecticidal action are lost if the wood impregnated therewith is exposed to the weather.
Eine Verringerung der Wirkkonzentration und eine Ver¬ besserung der Langzeitwirkung der polymeren quartären Ammoniumborate wird erreicht, wenn diese mit Kupfersalz und Alkanolamin kombiniert werden, wie dies aus EP-A 0 556 454 bekannt ist. Leider werden in diesen Mitteln toxische Kupferverbindungen eingesetzt. Es ist daher Aufgabe der Erfindung, schwermetallfreie, lösemittelfreie vorbeugende Holzschutzmittel mit guter r- fungizider Wirkung bereitzustellen, die auch bei Bewit¬ terung eine gute Langzeitbeständigkeit haben.A reduction in the active concentration and an improvement in the long-term effect of the polymeric quaternary ammonium borates is achieved if these are combined with copper salt and alkanolamine, as is known from EP-A 0 556 454. Unfortunately, toxic copper compounds are used in these agents. It is therefore an object of the invention to provide heavy metal-free, solvent-free preventive wood preservatives with good fungicidal activity, which have good long-term stability even when weathered.
Die Lösung der Aufgabe erfolgt durch Holzschutzmittel gemäß der Ansprüche 1-5.The problem is solved by wood preservatives according to claims 1-5.
Es wurde gefunden, daß Kombinationen von polymeren quartären Ammoniumboraten und (4-Ethoxyphenyl)- (3-(4-fluoro-3-phenoxy-phenyl)propyl-(dimethyl)silan mit Wasser klare Lösungen bilden, daß diese Lösungen und die in ihnen gelösten Wirkstoffe tief in Holz ein¬ dringen, nach der Trocknung nicht mehr auswaschen und auch bei geringer Einbringmenge eine gute insektizide und fungizide Langzeitwirkung ergeben.It has been found that combinations of polymeric quaternary ammonium borates and (4-ethoxyphenyl) - (3- (4-fluoro-3-phenoxy-phenyl) propyl- (dimethyl) silane with water form clear solutions that these solutions and those in them dissolved active ingredients penetrate deeply into wood, do not wash out after drying and have a good long-term insecticidal and fungicidal action even when the amount is small.

(3-(4-fluoro-3-phenoxy-phenyl)propyl(dimethyl)silan ist aus JP-A 61 229883 als insektizid wirkende Verbindung bekannt und unter dem Handelsnamen Silafluofen erhält¬ lich. Die Verbindung ist allerdings in Wasser unlöslich und dringt schlecht in Holz ein, auch wenn sie z.B. in Form einer Lösung in einem organischen Lösemittel auf Holz aufgebracht wird.(3- (4-fluoro-3-phenoxy-phenyl) propyl (dimethyl) silane is known from JP-A 61 229883 as an insecticidal compound and is available under the trade name Silafluofen. However, the compound is insoluble in water and does not penetrate well in wood, even if it is applied to wood in the form of a solution in an organic solvent.
Durch Kombination der beiden Komponenten ergibt sich ein mehrfacher synergistischer Effekt: Die Kombination wird wasserlöslich. Sie dringt tief in damit behandel¬ tes Holz ein und das Auswaschverhalten von polymerem quartärem Ammoniumborat wird deutlich reduziert.The combination of the two components results in a multiple synergistic effect: the combination becomes water-soluble. It penetrates deeply into the wood treated with it and the washout behavior of polymeric quaternary ammonium borate is significantly reduced.
Die erfindungsgemäße Wirkstoffkombination kann weitere verträgliche Wirkstoffe enthalten. Insbesondere emp¬ fiehlt sich der Zusatz eines Produktes aus 25-75 Gew.-Teilen Fettaminethoxylat und 75-25 Gew.-Teilen ungesättigter Fettsäure. Der Zusatz dieses, aus einer älteren Anmeldung der Anmelderin (P 195 15 211.5) be¬ kannten Produktes ergibt eine weitere Verbesserung der Eindringtiefe in das Holz und erlaubt eine weitere Re¬ duzierung der Wirkstoffmengen.The active ingredient combination according to the invention can contain further compatible active ingredients. In particular, the addition of a product of 25-75 parts by weight of fatty amine ethoxylate and 75-25 parts by weight is recommended unsaturated fatty acid. The addition of this product, known from an earlier application by the applicant (P 195 15 211.5), results in a further improvement in the depth of penetration into the wood and permits a further reduction in the amounts of active substance.
