Description

Herstellung pastenförmiger Imprägnierstoffe für Holzschutzzwecke Bei dem soggenannten Osmoseverfahren und der Pastentechnik werden bekanntlich wasserlösliche Schutzstoffe als Pasten auf das zu schützende Holz aufgetragen, die dann -infolge der eintretenden Dif-. fusion ins Holzinnere eindringen. Diese Verfahren sind zweifellos eine Ergänzung und Bereicherung der Holzschutztechnik, ihre erfolgreiche Durchführung läßt sich, nur mit dafür besonders geeigneten Pasten. bewirken. Neben der für das Verstreichen erforderlichen Konsistenz müssen sie beispielsweise folgende Eigenschaften besitzen: Haftfestigkeit, möglichst auch an senkrechten Flächen, kein Abblättern oder vorzeitiges Austrocknen, keine Beeinträchtigung der Diffusionsvorgänge innerhalb der Pastenschicht und im Holz durch den Pastenbildnar, Wirksamkeit desselben in verhältnismäßig geringer Menge usw.Manufacture of paste-like impregnation materials for wood protection purposes the so-called osmosis process and the paste technique are known to be water-soluble Protective substances are applied as pastes to the wood to be protected, which then - as a result the entering dif-. fusion penetrate the interior of the wood. These procedures are unquestionable a complement and enrichment of wood protection technology, its successful implementation can only be done with particularly suitable pastes. cause. In addition to the For example, they must have the following properties when spreading the required consistency Have: Adhesion, if possible also on vertical surfaces, no flaking or premature drying out, no impairment of the diffusion processes within the paste layer and in the wood through the paste form, effectiveness of the same in relatively small amount, etc.

Die bisher in der Praxis hierfür benutzten Kolloid- und Klebstoffe, wie beliebige Stärken, Dextrin und Gummiarabikum, befriedigten nicht immer, insbesondere versagten sie bei der Herstellung von Pasten mit höherem Salzgehalt aus leichtlöslichen. Salzen. Gerade das Aufbringen derartiger Sulze und Salzgemische in Pastenform ist aber im Zuge der neuesten Entwicklung der Holzschutztechn.ik bedeutungsvoll geworden. Die Erfinder fanden schließlich einen Weg zur Herstellung höchstwertiger homogener Pasten von salbigem Charakter und sonstigen erwünschten Eigenischaften aus leichtlöslichen Salzen durch Zusatz bestimmter Suspensatoren, gegebenenfalls unter Zusatz viskoser Verdünnungsmittel, z. B. Glycerin, Schleime, Leim us,w. Nach den, bisher vorliegenden Ergebnissen werden z. B. brauchbare Pasten der genannten Art erhalten durch Zufügen vorn 8 bis 10 °!o Aluminiumpalmitat zu 1 Teil Schutzmittel, z. B: Alkgibifluoride und deren Gemische, -I- 0,75 Teilen Wasser oder entsprechenden Mengen von Zink- oder Magnesiumstearat.The colloids and adhesives previously used in practice for this purpose, like any starches, dextrin and gum arabic, did not always satisfy, in particular they failed to produce pastes with a higher salt content from easily soluble ones. Salt. It is precisely the application of such sulphate and salt mixtures in paste form but has become significant in the course of the latest developments in wood protection technology. The inventors finally found a way to produce the highest quality homogeneous ones Pastes of saline character and other desirable properties of easily soluble Salts by adding certain Suspensators, if necessary under Addition of viscous diluents, e.g. B. glycerine, slime, glue, etc., w. After the, results available so far are z. B. useful pastes of the type mentioned obtained by adding 8 to 10 °! o aluminum palmitate to 1 part protective agent, z. B: Alkgibifluoride and their mixtures, -I- 0.75 parts of water or equivalent Amounts of zinc or magnesium stearate.
