Description

Verfahren zur Herstellung von Anstrichmässen Gegenstand der vorliegenden Erfindung ist die Herstellung von gegebenenfalls Pigmente ,enthaltenden Anstrichmassen in trockener Pulverform durch Vermischen von gebranntem Weißkalk mit Aluminiumsulfat undeinem Polymeren des Formaldehyds, z. B. Paraformaldehyd.Process for the production of paint measures the subject of the present The invention is the production of paint compositions optionally containing pigments in dry powder form by mixing quick white lime with aluminum sulfate and a polymer of formaldehyde, e.g. B. Paraformaldehyde.

Das Wesen der Erfindung besteht darin, daß nur feste und trockene Ausgangsmaterialen miteinander vermischt werden, die beim Anrühren mit Wasser und Aufstreichen auf Innen- öder Außenwände von Gebäuden zu beständigen Überzügen führen.The essence of the invention is that only firm and dry Starting materials are mixed together when mixed with water and Spreading on the inside or outside walls of buildings leads to permanent coatings.

Es ist zwar bekannt, daß Anstrichmittel, enthaltend gebrannten Weißkalk, Alaun und wässerige Formaldehydlösungen, @ebenfallsb,estämdige Anstriche ergeben. Diese Verfahren haben aber den Nachteil, daß sich der Formaldehyd beim Eintrocknen der An--strichmasse verflüchtigt, so daßa die desinfizierende Wirkung schon nach kurzer Zeit erloschen isst. Auch die Überführung solcher Anstrichm;assen durch Eindampfen .in trokkeine Pulverform führt zu dem gleichen negativen Ergebnis, da nach dem Eindampfen in er zurückbleibenden trocknen Anstrichmasse kein Formaldehyd mehr vorhanden ist und demnach auch keine desinfizierende Wirkung beim Wiederanrühren mit Wasser und Aufstreichen vor-sich gehen kann.It is known that paints containing burnt white lime Alum and aqueous formaldehyde solutions, @ alsob, produce earthy paints. However, these processes have the disadvantage that the formaldehyde dissolves on drying the coating material evaporates, so that the disinfecting effect already lingers a short time extinguished eats. Also the transfer of such paints by evaporation .in dry no powder form gives the same negative result as after evaporation there is no longer any formaldehyde in the dry paint that remains and therefore no disinfecting effect when mixed with water and Spreading can go on.

Im Gegensatz hierzu wird bei der Herstellung der Anstrichmassen nach dem vorliegenden Verfahren nur mit den trockenen Polymeren des Formaldehyds gearbeitet, die mit Bezug auf Desinfektionskraft lange Zeit beständig sind und deren hauptsächlichsten Vertreter die folgenden Körper darstellen: a-Polyoxymethylen, Schmelzpunkt 163' C, ß-Polyoxymethylen, y-Polyoxymethylen, ö-Polyoxymethylen, s-Polyoxymethylen, Trioxymethylen, Schmelzpunkt 6q." C, ringförmige Struktur, Tetraoxymethylen, Schmelzpunkt I I2° C, ringförmige Struktur.In contrast to this, in the production of the paints the present process only worked with the dry polymers of formaldehyde, which are stable for a long time in terms of disinfecting power and are the main ones Representatives represent the following bodies: a-polyoxymethylene, melting point 163 ' C, ß-polyoxymethylene, γ-polyoxymethylene, δ-polyoxymethylene, s-polyoxymethylene, trioxymethylene, Melting point 6q. "C, ring-shaped structure, tetraoxymethylene, melting point I 12 ° C, ring-shaped structure.

Die Struktur der meisten dieser Verbindungen ist noch unbekannt, ihre Herstellung ist zum. Teil aus der Patentliteratur b,ekannt, vgl. z. B.: amerikanische Patentschrift 1 666 7o8, britische Patentschrift 26o 9o8, französische Patentschrift 617 032. The structure of most of these compounds is still unknown. Part from the patent literature b, e known, cf. E.g .: American patent specification 1 666 708, British patent specification 26o 9o8, French patent specification 617 032.

Bei der Ausführung des Verfahrens, kommt es ferner darauf an, daß auf Grund der gewählten Mengenverhältnisse beim Anmachen mit Wasser die schwefelsaure Tonerde restlos durch den Kalk in Gips und Aluminiumhydroxyd übergeführt wird, z. B. ,nach folgender Gleichung: . 3 Ca (O H)2-;-Al. (S04)3 2A1 (O H)3+33 Ca, S04. Im Gegensatz zu den bekannten Verfahren, bei denen infolge des Alkalisalzgehaltes des Alauns nebenbei leicht lösliche Salze bei der Umsetzung entstehen, werden nach dem vorliegenden Verfahren nur schwer lösliche Verbindungen gebildet, wodurch eine erhöhte. Beständigkeit erreicht wird.When carrying out the process, it is also important that due to the chosen proportions when mixing with water, the sulphate of alumina is completely converted into gypsum and aluminum hydroxide by the lime, e.g. B., according to the following equation:. 3 Ca (OH) 2 -; - Al. (S04) 3 2A1 (OH) 3 + 33 Ca, SO4. In contrast to the known processes in which, as a result of the alkali salt content of the alum, easily soluble salts are also formed during the reaction, the present process only forms compounds that are difficult to dissolve, resulting in increased. Consistency is achieved.

Die Herstellung der Anstrichmasaen gemäß der Erfindung geschieht in der Weise, daß die drei Bestandteile in feinster Form miteinander vermahlen werden, und zwar nach dem in folgenden Beispielen ,gegebenen Mischungsverhältnis: Beispiel 3 5 o Teile gebrannter Kalk, 20 - Alunäniumsulfat, 5 - y-Polyoxymethylen, grünes Pigment. .. Beispiel q. 5o Teile ,gebrannter Kalk, 20 - Aluminiumsulfat, 5 - Trioxymethylen, 10 - Zinnober. Beispiel 5 5o Teile gebrannter Kalk, 20 - Aluminiumsulfat, 5 - Tetraoxymethylen, 10 - Ledergelb. Zwecks Überführung in den streichfertigen Zustand werden diese Mischungen mit 25o Teilen kaltem Wasser angemacht. Die Viscosität der angemachten Massen kann nach Erfordernissen geändert werden.The preparation of the paints according to the invention is done in such a way that the three components are ground together in the finest form, in accordance with the mixing ratio given in the following examples: Example 3 5 o parts quicklime, 20 - aluminum sulfate, 5 - γ-polyoxymethylene, green pigment. .. example q. 50 parts, quicklime, 20 - aluminum sulfate, 5 - trioxymethylene, 10 - cinnabar. Example 5 50 parts quicklime, 20 - aluminum sulfate, 5 - tetraoxymethylene, 10 - leather yellow. To make them ready for use, these mixtures are mixed with 250 parts of cold water. The viscosity of the prepared masses can be changed as required.
