Description

Wasserlösliches, der Konservierung und dem Schwerentflammbarmachen von Holz und anderen brennbaren Werkstoffen dienendes Imprägniermittel Es sind bereits Mittel bekannt, die sich aus Biehromat, Kupfersulfat, Zinkchlorid und Borsäure in wäßriger Lösung zusammensetzen. Während ein solches Mittel Holz und andere Materialien in. zufriedenstellender Weise gegen Zerstörung durch tierische oder pflanzliche Organismen schützt, ist seine feuerhemmende Wirkung nicht befriedigend.Water-soluble, preservation and making it flame-retardant Impregnating agent used for wood and other combustible materials There are already Known means consisting of Biehromat, copper sulfate, zinc chloride and boric acid in Compose aqueous solution. While such means wood and other materials in. Satisfactory manner against destruction by animal or vegetable Protects organisms, its fire retardant effect is not satisfactory.

Das Mittel gemäß der Erfindung besteht aus einem pulverförmigen Gemisch, das vor seiner Verwendung in Wasser aufgelöst wird und Bidhromat, Borsäure, Monoammoniumphosphat, Kupfersulfat oder -chlorid, Zink- oder Nickelsalze und eine zur Bildung von löslichen Metallchelaten geeignete Verbindung enthält, von denen letztere dazu dient, das Niederschlagen irgendeines der Salze in der Lösung zu verhindern, ,venn das Mittel in Wasser in Lösung gebracht wird. Eine derartige Verbindung ist z. B. Natriumpolyphosphat. Insbesondere eignet sich für diesen Zweck Natriumhexametaphosphat.The agent according to the invention consists of a powdery mixture, which is dissolved in water before use and Bidhromat, boric acid, monoammonium phosphate, Copper sulfate or chloride, zinc or nickel salts and one to form soluble ones Metal chelates contains suitable compound, the latter of which serves to the To prevent any of the salts from precipitating in the solution, use the agent is brought into solution in water. Such a connection is e.g. B. sodium polyphosphate. Sodium hexametaphosphate is particularly suitable for this purpose.

Die vorstehend erwähnten Salze werden in einer solchen Menge Wasser gelöst, daß eine Lösung entsteht, die etwa 16 Gewichtsprozent Salze enthält. Mit einer derartigen- Lösung werden die zu behandelnden Materialien nach an sich bekannten Verfahren, z. B. Holz nach dem imprägniert.Examples of mixtures according to the invention are the following, in which the figures express percentages by weight: Example 1 Boric acid. . . ,. . . . . . . . . . . . . . . ,. . . . . . . . . 14.5% Sodium hexametaphosphate. . . . ,. . . . . . . . 14.5.1 / 0.

The above-mentioned salts are dissolved in such an amount of water that a solution is formed which contains about 16 percent by weight of salts. With such a solution, the materials to be treated are prepared by methods known per se, e.g. B. Wood after being impregnated.
