GROUP Gegenstand der vorliegenden Erfindung ist ein Anstrich, mit Hilfe dessen es möglich ist, Holz u. dgl. fäulniswidrig und feuerfest zu machen.The subject of the present invention is a paint with the help of which it is possible To make wood and the like rot-resistant and fireproof. Dieser Anstrich besteht im wesentlichen aus Chlormagnesiumlauge, Asbest, Magnesiumoxyd und Sand.This coating consists essentially of magnesium chloride, asbestos and magnesium oxide and sand. Es wurde gefunden, daß konzentrierte Chlormagnesiumlösung die Eigenschaft zeigt, AsbestIt has been found that concentrated magnesium chloride solution exhibits the property of being asbestos ίο derart fein zu zerteilen, daß eine auf diese Weise hergestellte Emulsion, die 40 bis 50 g Asbest in ι 1 konzentrierter Chlormagnesmmlösung enthält, sich rückstandslos durch die allerfeinsten Haarsiebe drücken läßt. Der auf diese Weise erzeugte schleimige Brei liefert, mit einem innigen Gemisch von gebrannter Magnesia und feingemahlenem Sand gut durchmischt, eine Anstrichmasse, die dem damit überzogenen Holz hervorragende Feuerfestigkeit verleiht. Zur Herstellung der Asbestemulsion eignen sich 20 bis 36prozentige Magnesiumchloridlösungen ; den Asbest selbst verwendet man am besten in Form von zerzupftem Fadenasbest. Es genügt, wie erwähnt, einfaches Anrühren von wenigen Minuten Dauer in einer Reibschale o. dgl., um die feinstmögliche Verteilung zu erreichen. Bei größeren Mengen rührt man Lauge und Asbest in einem Mörtelfaß 1Z2 Stunde lang mit einem Holzscheit kräftig durcheinander und erreicht dasselbe Resultat. Alsdann setzt man eine trockene gleichmäßige Mischung von z. B. To divide so finely that an emulsion produced in this way, which contains 40 to 50 g of asbestos in 1 concentrated chlorine magnesium solution, can be pressed through the very finest hair sieves without leaving any residue. The slimy pulp produced in this way, well mixed with an intimate mixture of burnt magnesia and finely ground sand, provides a paint which gives the wood coated with it excellent fire resistance. 20 to 36 percent magnesium chloride solutions are suitable for producing the asbestos emulsion; the asbestos itself is best used in the form of torn thread asbestos. As mentioned, it is sufficient to simply stir for a few minutes in a mortar or the like in order to achieve the finest possible distribution. For larger amounts, stir the lye and asbestos in a mortar barrel for 1 Z 2 hours with a wooden log and achieve the same result. Then you put a dry even mixture of z. B. 2 Teilen feinstgemahlenem Sand mit 1 Teil ebensolcher gebrannter Magnesia so lange zu, bis das Endprodukt, die fertige Anstrichmasse, eben noch streichbar ist. Nach 24 Stunden ist die Masse erhärtet und verleiht dem damit überzogenen Brettstück z. B. eine derartige Feuersicherheit, daß die intensive Hitze einer Kesselfeuerung beispielsweise das Holz wohl verkohlt, aber nicht imstande ist, es zur Entflammung zu bringen.2 parts of finely ground sand with 1 part the same amount of burnt magnesia until the end product, the finished paint, is just paintable. After 24 hours the mass has hardened and thus gives it coated piece of board z. B. such a fire safety that the intense heat a boiler, for example, the wood is likely to be charred, but not able to use it To inflame.
