Description
Hydrogenfluoride enthaltende Holzschutzmittel Als Schutzmittel für Holz gegen tierische und pflanzliche Schädlinge sind Hydrogenfluoride bzw. Salzgemische, die Hydrogenfluoride enthalten und die als wäßrige Lösungen auf die zu schützende Holzoberfläche aufgetragen werden, bekannt. Man hat festgestellt, daß diese Salze das im Holz vorhandene Baueisen mehr oder weniger angreifen und verwendet diese Salze deshalb mit Zusätzen, die die korrodierenden Eigenschaften der Schutzmittel mildern. Hierfür sind besondere Mittel bekannt, die die saure Wirkung der Hydrogenfluoride abstumpfen.Wood preservatives containing hydrogen fluorides As protective agents for Wood against animal and vegetable pests are hydrogen fluorides or salt mixtures, which contain hydrogen fluorides and which are used as aqueous solutions on the to be protected Wood surface are known. It has been found that these salts attack the existing construction iron in the wood more or less and use it Therefore salt with additives that reduce the corrosive properties of the protective agent mitigate. For this purpose, special agents are known that reduce the acidic effect of hydrogen fluorides dull.
Erfindungsgemäß wird den Hydrogenfluoride enthaltenden Holzschutzmitteln zur Korrosionsverhinderung Molybdän in Form wasserlöslicher Salze, z. B. als Ammoniummolybdat, Natriummolybdat od. dgl., zugesetzt.According to the invention, the wood preservatives containing hydrogen fluorides to prevent corrosion molybdenum in the form of water-soluble salts, e.g. B. as ammonium molybdate, Sodium molybdate or the like added.
Es wurde festgestellt, daß man nur sehr geringe Zusätze dieser Salze zur Erzielung eines wirksamen Korrosionsschutzes benötigt und daß die Wirkung merklich nachläßt, wenn man die als Bestwerte festgestellten Zusatzmengen merklich vergrößert oder vermindert.It was found that only very small amounts of these salts were added needed to achieve effective protection against corrosion and that the effect is noticeable diminishes if the additional amounts determined as the best values are increased noticeably or diminished.
So führte ein Dauertauchversuch bei 20° C nach DIN 50 905 bei einem
Gemisch von 87% Ammoniumhydrogenfluorid und 10% Kaliumhydrogenfluorid zu folgenden
Ergebnissen:
In diesem großen Korrosionsschutz liegt ein erheblicher Fortschritt, der die Brauchbarkeit von Hydrogenfluo@ride enthaltenden Holzschutzmitteln wesentlich steigert. Der geringe Prozentsatz. des Zusatzes beeinträchtigt auch nicht die Schutzwirkung des Salzes, ein Nachteil, den besonders die alkalisiezend wirkenden Korrosionsschutzmittel haben, die in recht erheblichen prozentualen Anteilen benötigt werden, wenn sie überhaupt einen wirksamen Korrosionsschutz herbeiführen sollen. Auch eine Verteuerung des Mittels tritt bei dem geringen Zusatz nicht ein.There is considerable progress in this great protection against corrosion, the usefulness of Hydrogenfluo @ ride containing wood preservatives is essential increases. The low percentage. the additive does not affect the protective effect of the salt, a disadvantage, especially the anti-corrosion agents which have an alkaline effect which are needed in quite substantial percentages if they are should bring about effective corrosion protection at all. Also an increase in price of the agent does not occur with the small addition.
