Description
Verfahren zur Herstellung wetterfester Kalkanstrichmassen und Anstrichfarben -Die- rfindüng - betrifft die Herstellung wetterfester kälkansfrich-masserrun stnc# farben in Brei- oder Teigform. Die nach der Erfindung hergestellten Anstrichmassen und Anstrichfarben zeichnen sich im Gebrauch durch feste Haftung auf den damit behandelten Flächen sowie durch ihre Wetterfestigkeit und ferner auch dadurch aus, daß die damit behandelten Gegenstände, wie Holzbalken u. dgl., auch im gewissen Grade fäulnis- und flammenfest gemacht werden.Process for the production of weatherproof lime paints and paints -Die rfindüng - concerns the production of weatherproof kälkansfrich-masserrun stnc # colors in porridge or dough form. The paint compositions produced according to the invention and paints, in use, are characterized by firm adhesion to those treated with them Surfaces as well as by their weather resistance and also by the fact that the with it treated objects, such as wooden beams and the like, also to a certain extent rotten and made flameproof.
Besonders geeignet sind die Anstrichmassen und Anstrichfarben der vorliegenden Art u. a. auch zu Anstrichen für Hausfassaden und für nasse Räume bzw. z. B. für Fabrikräume, in denen mit Wasserdämpfen u. dgl. gearbeitet wird.The paints and paints are particularly suitable present type, inter alia. also for painting house facades and for wet rooms or z. B. for factory rooms in which water vapors and the like are used.
Zur Herstellung von Anstrichmassen und Anstrichfarben der neuen Art wird ein durch Ablöschen von gebranntem Weißkalk mit Wasser' oder in ebenfalls bekannter Weise mit dünnen, wäßrigen Lösungen von Kochsalz Natronlauge o. dgl. hergestellter Kalkbrei nach oder kurz vor Beendigung des Löschvorgangs mit handelsüblicher Formaldehydlösung versetzt.For the production of paints and paints of the new kind is also known by quenching burnt white lime with water 'or in the same way Way with thin, aqueous solutions of sodium hydroxide solution or the like Lime paste after or shortly before the end of the extinguishing process with commercially available formaldehyde solution offset.
Gemäß einer zweckmäßigen Ausführungsart des Verfahrens werden die Zusatzmengen an handelsüblicher Formaldehydlösung etwa in den Grenzen von, 5 bis i o % der Gewichtsmenge des Trockenkalkgehalts des Kalkbreis gehalten. Etwaige übliche Farbzusätze werden der -Musse.-nach _ dem Ablöschen, zweckmäßig vor ihrer gebrauci#sfertigen-Verd_ünnung,___vQrzugsweise in Gestalt von Ürd- uncr- Kalkfarben= beigemengt.According to an expedient embodiment of the method, the Additional amounts of commercially available formaldehyde solution in the range from .5 to i o% of the weight of the dry lime content of the lime slurry held. Any usual Color additives are required after they have been extinguished, appropriately before they are ready for use, dilution, preferably in the form of crude and lime paints = added.
Eine brauchbare Anstrichmasse in Brei-oder Kalkform erhält man beispielsweise durch Ablöschen von i oo kg gebranntem Kalk mit etwa 200 kg wäßriger Löschungsflüssigkeit, in der etwa i o kg Kochsalz und S kg Alaun, sowie 5 kg etwa i 4prozentige Natronlauge gelöst sein können. Dem so erhaltenen Kalkbrei werden erfindungsgemäß nach dem Ablöschen oder auch kurz vor Beendigung dieses Vorgangs 5 kg handelsüblicher Formaldehydlösung hinzugefügt. . Statt eines Zusatzes von 5 kg Natronlauge und von nur 5 kg handelsüblicher Formaldehydlösungkann auch ein Zusatz von iokg Formaldehydlösung gemacht werden.A useful paint composition in slurry or lime-obtained, for example by slaking of i oo kg quicklime with about 200 kg of aqueous quenching liquid in which about io kg common salt and S kg alum, and can be released for 5 kg about i 4 per cent sodium hydroxide solution. According to the invention, after the extinguishing or shortly before the end of this process, 5 kg of commercially available formaldehyde solution are added to the lime paste obtained in this way. . Instead of adding 5 kg of sodium hydroxide solution and only 5 kg of commercially available formaldehyde solution, 10 g of formaldehyde solution can also be added.
Nach diesem Verfahren wird eine breiförmige Masse erhalten; die zweckmäßig erst an der Verbrauchsstelle unter Zugabe von etwa weiteren zoo kg Wasser streichfertig gemacht wird. Wie oben :erwähnt, werden die Farbzusätze zweckmäßig vor der Verdünnung hinzugefügt.A pulpy mass is obtained by this process; the functional Only ready to use at the point of use with the addition of about another zoo kg of water is made. As mentioned above, the color additives are expedient before the dilution added.
Durch den Formaldehydzusatz werden die Kalkanstrichmassen auch für Lagerung und Versand haltbarer gemacht, während gleichzeitig bei ihrer Verarbeitung eine besonders gute Haftfähigkeit auch auf feuchten und bereits mit anderen Anstrichmassen oder Anstrichfarben behandelten Flächen erzielt wird, so daß in Verbindung mit den eingangs ._e_r:s, wähnten Vorteilen ein erheblicher technisei'~` Fortschritt auf dem Gebiet der Anstriche, nik gemäß dem vorliegenden Verfahren':.ge;" währleistet ist.With the addition of formaldehyde, the lime paints are also suitable for Storage and shipping made more durable while simultaneously processing them a particularly good adhesion even on damp and already surfaces treated with other paints or paints are achieved, so that in connection with the initially ._e_r: s, mentioned advantages a considerable technisei '~' progress in the field of painting, nik according to the present Procedure ':. Ge; "is guaranteed.
