Description
Verfahren zum Schutze von Holz gegen Feuer durch Imprägnierung Feuerhemmende Anstriche auf Basis der Oxychloride der alkalischen Erden bzw. des Magnesiums, z. B. 3 Ca0, CaCl2, 15 H20 - 3 M90, M9C12, 12 H20, sind bereits vorgeschlagen worden. Sie haben sich als Holzschutz gegen Feuer, ja sogar gegen Phosphor bewährt.Process for protecting wood against fire by impregnation fire retardant Paints based on the oxychloride of alkaline earths or magnesium, e.g. B. 3 Ca0, CaCl2, 15 H20-3 M90, M9C12, 12 H20, have already been proposed. They have proven themselves as wood protection against fire, and even against phosphorus.
Erst der erfinderische Gedanke, die Bildung der Oxychloride im Innern des Holzes zu vollziehen, gab die Möglichkeit, auch eine Imprägnierung des Holzes auf dieser Basis zu schaffen.First the inventive idea, the formation of the oxychloride inside of the wood gave the opportunity to also impregnate the wood to create on this basis.
An sich sind die angewandten Salze im einzelnen als mehr oder minder gute Feuerschutzmittel bekannt. Der große technische Fortschritt liegt auch nicht etwa in der Kombination dieser, sondern in der fällenden, porenfüllenden Bildung des Oxychlorides mitten im Holz. Das Oxychlorid hat als Komplexsalz mit einem Kristallwassergehalt von etwa 5o0/, und infolge seiner Basizität ganz andere Eigenschaften als die einzelnen Reaktionskomponenten oder selbst wie eine wahllose Kombination dieser Komponenten.As such, the salts used are more or less in detail known good fire retardants. The great technical progress does not lie either for example in the combination of these, but in the precipitating, pore-filling formation of oxychloride in the middle of the wood. The oxychloride has a complex salt with a water of crystallization content of about 50 /, and, due to its basicity, quite different properties than the individual ones Reaction components, or even like an arbitrary combination of these components.
Die einzelnen Komponenten, d. h. in diesem Falle die verschiedenen Imprägnierlösungen, sind so aufeinander abgestimmt, daß äquivalente Mengen zur Bildung der Oxychloride gemäß obigen Formeln angewandt werden, wobei mitunter sogar ein Überschuß an Oxyd bzw. Hydroxyd erwünscht oder sogar notwendig sein kann, weil dadurch Wasserunlöslichkeit erzielt wird. Dies ist z. B. beim Calciumoxychlorid notwendig, weil dieses an sich leicht durch Wasser spaltbare Salz im Überschuß d'es Kalkhydrats wasserunlöslich wird.The individual components, i.e. H. in this case the different ones Impregnation solutions are coordinated in such a way that equivalent amounts are used for the formation of the oxychlorides according to the above formulas are used, sometimes even a Excess of oxide or hydroxide may be desirable or even necessary because it means Water insolubility is achieved. This is e.g. B. necessary for calcium oxychloride, because this salt, which in itself is easily split by water, has an excess of hydrated lime becomes insoluble in water.
Die ausgezeichnete Schutzwirkung der Oxychloride im Holz kann noch durch bekannte, auch sonst für diese Zwecke angewandte Zusätze (wasserlösliche Harnstoffharze, Leime) gesteigert werden. Es tritt tatsächlich eine gewisse Versteinerung des Holzes ein, viel weitgehender als das seither durch die Aufbringung von Oxychloridanstrichmassen möglich war. Wurde doch schon selbst ,die Aufbringung derartiger Anstriche z. B. als vollständige Versteinerung von Holzbrücken angesprochen.The excellent protective effect of the oxychloride in wood can still through known additives that are also used for these purposes (water-soluble urea resins, Glues) can be increased. There is actually some petrification of the wood a, Much more extensive than that since then through the application of Oxychloride paint was possible. It was already itself, the raising of such a thing Paints z. B. addressed as complete petrification of wooden bridges.
