Description
Holzschutzmittel auf Hydrogenfluorid-Basis Man kennt Holzschutzmittel zum vorbeugenden Schutz gegen tierische und pflanzliche Schädlinge oder zu ihrer Bekämpfung in bereits befallenem Holz, die auf unter anderem Ölbasis oder auf Hydrogenfluorid-Basis aufgebaut sind. Holzschutzmittel auf Hydrogenfluorid-Basis sind als Salze im Handel und werden erst an der Verwendungsstelle in Wasser gelöst; sie dringen verhältnismäßig tief in das zu behandelnde Holz ein.Hydrogen fluoride-based wood preservatives Wood preservatives are known for preventive protection against animal and vegetable pests or for their Combat in already infested wood, based on oil or hydrogen fluoride, among other things are constructed. Hydrogen fluoride-based wood preservatives are commercially available as salts and are only dissolved in water at the point of use; they penetrate proportionally deep into the wood to be treated.
Seit mehreren Jahren ist es üblich, den handelsüblichen Holzschutzmitteln auf Ölbasis Kontaktinsektizide zuzusetzen, um die Abtötungsgeschwindigkeit zu vergrößern und die Wirkung der Mittel zu steigern. Man benutzt als Kontaktinsektizide öllösliche organische Stoffe. Bei Holzschutzmitteln auf Hydrogenfluorid-Basis lassen sich diese Kontaktinsektizide nicht verwenden, weil sie nicht oder nur sehr wenig wasserlöslich sind und in Form von Emulsionen nicht genügend tief in das Holz eindringen.For several years it has been customary to use commercially available wood preservatives add oil-based contact insecticides to increase the rate of kill and to increase the effectiveness of the means. Oil-soluble insecticides are used as contact insecticides organic substance. In the case of wood preservatives based on hydrogen fluoride, these can be used Do not use contact insecticides because they are not or very little soluble in water and in the form of emulsions do not penetrate deep enough into the wood.
Aufgabe der Erfindung ist die Entwicklung eines Holzschutzmittels auf Hydrogenfluorid-Basis mit wirkungsbeschleunigenden Stoffen, die als wasserlösliches Salz dem als Salz im Handel befindlichen Holzschutzmittel auf Hydrogenfluorid-Basis zugesetzt sind.The object of the invention is to develop a wood preservative based on hydrogen fluoride with substances that accelerate the effect, which are water-soluble Salt the hydrogen fluoride-based wood preservative commercially available as salt are added.
Nach eingehenden Tierversuchen mit Anobiumpunetatum-Larven und auch mit großen Hausbocklarven wurde als Lösung der Aufgabe der erfindungsgemäße Vorschlag entwickelt, dem Holzschutzmittel auf Hydrogenfluorid-Basis, z. B. einem Gemisch aus Kaliumhydrogenfluorid und Ammoniumhydrogenfluorid, einen Zusatz von 0,0025 bis 1 Gewichtsprozent Natriummonofluoracetat beizugeben.After detailed animal experiments with Anobiumpunetatum larvae and also with large house buck larvae, the proposal according to the invention was the solution to the problem developed, the wood preservative based on hydrogen fluoride, z. B. a mixture of potassium hydrogen fluoride and ammonium hydrogen fluoride, an addition of 0.0025 to 1 percent by weight sodium monofluoroacetate to be added.
Das Ergebnis sei an folgenden Versuchsbeispielen erläutert 1. Einem handelsüblichen Hydrogenfluoridgemisch wurde 0,5% Natriumfluoracetat beigemischt. Von dem Gemisch wurde eine 20%ige Lösung in Wasser hergestellt. Mit der Lösung wurden nach DIN 52 623 Kiefern-Normklötzchen mit etwa 2,8 kg Salzgemisch, bezogen auf 1 cbm Holz, voll getränkt und anschließend 4 Wochen lang an der Luft gelagert. Danach wurden lebende Larven von Anobium punctatum in je eine Bohrung von einer Breitseite des Holzklötzchens aus eingebracht. Die mit den Larven versehenen Probeklötzchen wurden in Hygrostaten bei 20°C und 70 bis 75 % relativer Luftfeuchtigkeit untergebracht. Nach 4 Wochen wurde das Holz aufgespalten, und die Nachprüfung ergab, daß alle Larven tot waren.The result is explained using the following test examples 1. One commercial hydrogen fluoride mixture was admixed with 0.5% sodium fluoracetate. A 20% solution in water was made from the mixture. With the solution were according to DIN 52 623 pine standard blocks with about 2.8 kg salt mixture, based on 1 cbm wood, fully soaked and then stored in the air for 4 weeks. Thereafter were living larvae of Anobium punctatum in one hole each from one broad side of the wooden block introduced. The test blocks with the larvae were housed in hygrostats at 20 ° C and 70 to 75% relative humidity. After 4 weeks the wood was split open and inspection showed that all larvae were were dead.
2. Einem handelsüblichen Hydrogenfluoridgemisch wurde 1% Natriumfluoracetat beigemischt. Von dem Gemisch wurde eine 20%ige Lösung in Wasser hergestellt. Mit der Lösung wurden wie beim Versuch 1 Kiefernholzklötzchen getränkt und gelagert. Als Versuchstiere dienten diesmal größere, besonders giftresistente Hausbocklarven im Gewicht von etwa 200 mg. Bereits nach 4wöchiger Versuchsdauer waren alle Hausbocklarven tot und verfärbt. Die Abtötung muß sehr bald erfolgt sein, da sich die Tiere nicht eingebohrt hatten.2. A commercial hydrogen fluoride mixture was added 1% sodium fluoroacetate mixed in. A 20% solution in water was made from the mixture. With As in the experiment 1, pinewood blocks were soaked in the solution and stored. This time, larger, particularly poison-resistant house buck larvae served as test animals weighing about 200 mg. After just 4 weeks of the experiment, all of the house buck larvae were found dead and discolored. The killing must take place very soon, since the animals do not had drilled into them.
Verwendet man das Schutzsalz in einer Konzentration von 2,8 kg/m3 ohne Zusatz von Natriummonofluoracetat, so ergibt sich nach einer Versuchszeit von 4 Wochen im Durchschnitt für Anobienlarven eine tote vier lebende Larven und für große Hausbocklarven fünf lebende Larven.If the protective salt is used in a concentration of 2.8 kg / m3 without the addition of sodium monofluoroacetate, after a test time of 4 weeks on average for anobia larvae and for one dead four live larvae large house buck larvae five live larvae.
