Description

Anstrichmittel. Alle bisherigen Versuche, Zement als wesentlichen Bestandteil eines Anstrichmittels zu verwenden, begegneten in der Praxis der Schwierigkeit, daß die Masse zu schnell erstarrte und ihre Streichfähigkeit verlor. Besonders bei Anwesenheit von Wasserglas, diesem wichtigsten Bestandteil fast aller Mineralfarben, war das schnelle Hartwerden der zementhaltigen Masse ein Übelstand.Paints. All previous attempts at cement as essential Using a component of a coating material encountered the difficulty in practice that the mass solidified too quickly and lost its spreadability. Especially at Presence of water glass, this most important component of almost all mineral paints, the rapid hardening of the cementitious mass was a problem.

Dieser Mangel soll durch vorliegende Erfindung beseitigt werden, ohne daß dabei das Anstreichmittel die Eigenschaften der Widerstandsfähigkeit gegen Wasser und Atmosphärilien einbüßt, die ihm durch den Zement verliehen werden sollen.This deficiency is intended to be eliminated by the present invention, without that while the paint has the properties of resistance to water and forfeits the atmospheres that the cement is supposed to impart to it.

Zu diesem Zwecke wird der Zement nicht in der gewöhnlichen Form, sondern in einem besonders vorbereiteten und dadurch gekennzeichneten Zustand verwendet, daß unter dem Einfluß von Kohlensäure der im Zement enthaltene Ätzkalk in kohlensauren Kalk verwandelt wird. Dies kann beispielsweise dadurch geschehen, daß man etwa gleiche Teile Zement und fein gemahlene Tonerde, Talkum, Quarzmehl, Schwerspat oder andere Mineralien mischt und eine entsprechend konzentrierte, etwa 5oprozentige Lösung von alkalischen Karbonaten (kohlensaures Kali oder Natron) zusetzt. Der Ätzkalk des Zements entzieht alsdann dem Alkali die Kohlensäure. Der Vorgang kann durch unmittelbare Zuführung von gasförmiger Kohlensäure beschleunigt werden.For this purpose, the cement is not in the ordinary form, but rather used in a specially prepared and characterized condition, that under the influence of carbonic acid the quick lime contained in the cement is converted into carbonic acid Lime is transformed. This can be done, for example, by making about the same Share cement and finely ground clay, talc, quartz powder, barite, or others Mixes minerals and a correspondingly concentrated, about 5% solution of alkaline carbonates (carbonate of potash or soda) added. The quick lime The cement then removes the carbonic acid from the alkali. The process can go through direct supply of gaseous carbon dioxide can be accelerated.

Eine andere Ausführungsmöglichkeit besteht darin, daß man das Gemenge von .Zement und Tonerde oder ihren Äquivalenten in dünnen Schichten in einem kohlensäurehaltigen Raume ausbreitet, wobei die Kohlensäure künstlich, etwa durch Verbrennen von Koks in offenen Behältern, erzeugt werden kann.Another implementation option is that you get the mixture of .cement and clay or their equivalents in thin layers in a carbonated Spaces spreads, with the carbonic acid artificially, for example by burning coke in open containers.

Dem Zement, dessen Ätzkalk auf diese oder irgendeine andere Weise in kohlensauren Kalk verwandelt worden ist, werden entsprechende Mengen von Natron oder Kaliwasserglas hinzugesetzt. Ein -Zusatz von kohlensauren Alkalien schafft auch hierbei die Sicherheit, daß alle Zementteilchen der Einwirkung der Kohlensäure ausgesetzt worden sind.The cement, its quicklime in one way or another Has been converted into carbonate of lime, corresponding amounts are made of soda or potassium water glass added. An addition of carbonate creates Here too, the certainty that all cement particles are exposed to the action of carbonic acid have been exposed.

Eine als Anstrich verwendbare Mischung ist z. B. folgende: 2o Teile präparierter Zement, 2o Teile Tonerde oder ihrer Äquivalente, ro Teile Alkalikarbonat und 5o Teile Wasserglas von handelsüblicher Konsistenz. Dieser Mischung können noch entsprechende Mischungen von Buntfarben zugesetzt werden.A mixture which can be used as a paint is e.g. B. the following: 2o parts prepared cement, 20 parts alumina or its equivalents, ro parts alkali carbonate and 50 parts of water glass of commercial consistency. This mixture can still Appropriate mixtures of colored paints are added.

Eine solche Mischung hält sich selbst beim Stehen in offenen Gefäßen lange Zeit streichfähig und erfährt in geschlossenen Gefäßen fast gar keine Veränderung.Such a mixture holds itself in open vessels even when standing Can be spread for a long time and undergoes almost no change in closed containers.

Eine Lage des in vorbeschriebener Weise veränderten Zements gestattet auch einen Anstrich mit Ölfarbe, während sich sonst beim Aufbringen von Ölfarbe auf frischen Zement sehr bald eine wasserlösliche Kalkseife bildet.A position of the cement modified in the manner described above is permitted also a coat of oil paint, while otherwise when applying oil paint very soon forms a water-soluble lime soap on fresh cement.
