Description

Verfahren zur Herstellung eines mit einem Bindemittel ein Deckanstrichmittel ergebenden Festkörpers Die der Erfindung zugrunde liegende Aufgabe besteht darin, kristallisierte oder kristallinische Körper, die als Festkörper für Anstrichmittel Verwendung finden sollen, öl- oder lackdeckend zu machen, d. h. sie so zu verändern, daß sie mit Öl oder Lack zusammen-gemischt und verrieben ein deckendes Anstrichmittel ergeben. Bekanntlich behalten kristallisierte oder kristallinische Körper, wie z. B. Schwerspat, Kalkspat, Anhydrit, Quarz, Tonerdehydrat, trotz feiner Zertrümmerung ihre Kristallstruktur mit feinen Spitzen bei, die Veranlassung für das Entmischen der Festkörper aus Öl od. dgl. geben.Process for the production of a solid body which results in a topcoat with a binder The object underlying the invention is to make crystallized or crystalline bodies, which are to be used as solids for paints, opaque to oil or varnish, ie to change them so that they with Oil or varnish mixed together and rubbed together result in an opaque coating material. It is known to retain crystallized or crystalline bodies, such as e.g. B. barite, calcite, anhydrite, quartz, alumina hydrate, despite their fine fragmentation, their crystal structure with fine tips, the cause for the segregation of the solids from oil or the like. Give.

Die gestellte Aufgabe wird gemäß der Erfindung dadurch gelöst, daß man den Festkörper (Pigment) für Anstrichmittel in feiner Zerteilung mit einem dünnen Film eines wasserlöslichen, aber in 01 oder Lack unlöslichen bekannten: Kunststoffes umgibt, der zweckmäßigerweise durch ein geringeres Eigengewicht weiter das leichte Absetzen des Festkörpers verhindert.The object is achieved according to the invention in that the solid (pigment) for paint is finely divided with a thin film of a water-soluble, but insoluble in oil or paint, known: plastic, which expediently due to its lower weight, further the easy settling of the solid prevented.

Das neue Verfahren kann in der Weise ausgeführt werden, daß man: z. B. feinen Schwerspat mit Polyvinylal'kohol, Wasser und Ammoniumbichromat gründlich miteinander vermischt und dann das Gemisch beispielsweise auf einer Naßkolloidmühle verfeinert. Durch dieses innige Verreiben und Verfeinern des Schwerspats mit dem Gemisch von Polyvinylalkohol, Was ser undAmmonium, bich.romat wird erreicht, daß der Polyvinylalkohol zunächst in eine wäßrige Lösung übergeführt wird, so daß er sich in der Schwerspatpulvermasse gleichmäßig verteilen kann. Das in Wasser gelöste Ammoniumbichromat bewirkt allmählich ein Unlös.lichwerden; des Polyvinylalkohols, so daß nach einem Zeitraum von: etwa 1/2 Stunde jedes Kristallflitterchen von einem Film umgeben ist, der mehr oder weniger unlöslich geworden ist. Nach einem weiteren Zeitraum von etwa r Stunde ist die Reaktion zu Ende geführt, und der Filmüberzug ist genügend unlöslich geworden, so .daß er für das Bindemittel (Öl oder Lack) nicht mehr angreifbar ist.The new process can be carried out in such a way that: e.g. B. fine barite with polyvinyl alcohol, water and ammonium dichromate thoroughly mixed together and then the mixture, for example on a wet colloid mill refined. Through this intimate trituration and refinement of the barite with the Mixture of polyvinyl alcohol, water and ammonium, bich.romat is achieved that the polyvinyl alcohol is first converted into an aqueous solution so that it evenly in the heavy spar powder mass can distribute. That Ammonium dichromate dissolved in water gradually causes it to become insoluble; of Polyvinyl alcohol, so that after a period of: about 1/2 hour each crystal flake is surrounded by a film that has become more or less insoluble. After a the reaction is complete and the film is coated for a further period of about 1 hour has become sufficiently insoluble that it does not affect the binding agent (oil or varnish) is more vulnerable.

In .diesem Zustand bilden die einzelnen Schwerspaitteilchen mehr oder weniger eine flockige Gestalt ohne vorstehende Spitzen. Mit Öl zusammengemischt und darin gleichmäßig verteilt, bildet der Schwerspat einen außerordentlich gut brauchbaren Festkörper für Anstrichmittel, wie er durch mechanische Zertrümmerung niemals erreicht werden kann.In this state, the individual particles of heavy metal form more or more less of a flaky shape with no protruding tips. Mixed together with oil and evenly distributed in it, the barite is extremely good useful solids for paints, such as those produced by mechanical disintegration can never be achieved.

Zu dem Polyvinylalkohol kann man in der flüssigen Phase auch Farbstoffe hinzusetzen, die gleichmäßig mit auf die Schwerspatteilchen verteilt werden. Auf diese Weise erhält man einen außerordentlich wetterfesten, gefärbten Festkörper für Anstrichmittel, z. B. aus Schwerspat.Dyes can also be added to the polyvinyl alcohol in the liquid phase, which are distributed evenly over the barite particles. In this way, an extremely weatherproof, colored solid for paints, e.g. B. from barite.

In der Anstrichtechnrik ist es bekannt, zwecks Verhinderung des Zusammenbackens von Pigmenten diese mit einem dünnen Häutchen eines Öls zu überziehen. Beispiel 84 Teile von: gemahlenem Schwerspat versetzt man mit 15 Teilen Wasser, 1/2 Teil Polyvinylalkohol und etwa 1/4 Teil Ammoniumbichromat, rührt das Gemisch mehrere Stunden in einem Schnellmischer, bringt die entstandene Masse in einem Sprühtrockner zur Trockne und. erhält ein rein weißes Pulver von besonderer Feinheit, das in seinem kolloidalen Zustand gefälltes Bariumsulfat bei weitem übertrifft.It is known in painting technology to prevent caking of pigments to coat them with a thin membrane of an oil. example 84 parts of: ground barite are mixed with 15 parts of water, 1/2 part Polyvinyl alcohol and about 1/4 part ammonium dichromate, stir the mixture several times Hours in a high-speed mixer, put the resulting mass in a spray dryer to dryness and. receives a pure white powder of particular fineness, which in his colloidal state of precipitated barium sulfate by far exceeds.
