Abstract
Description
Zur Einfärbung von Beton mit Eisenoxid-Farben benutzte man bisher Eisenoxid-Pigmente in Pulverform, nachteilige Wirkung waren ungenaue Dosierung und starke Verschmutzung durch enorme Staubentwicklung.Used to color concrete with iron oxide paints previously iron oxide pigments in powder form, disadvantageous The effects were inaccurate dosing and heavy soiling through enormous dust generation.
Ein anderes Verfahren stellt zunächst ein Slurry der Eisenoxid-Pigmente her, der wegen seiner hohen Viskosität und Dichte zur Inhomogenität und Agglomerierung neigt. Dadurch kann es zu unegalen Einfärben des Betons kommen, wobei z. B. Streifen oder Flecken wegen der hohen Dichte entstehen können. Der Slurry neigt zur Sedimentation und Aufrahmung. Wegen der schlechten Stabilität muß der Slurry bewegt werden. Hervorzuheben ist noch die schlechte Dosierbarkeit.Another method is a slurry Iron oxide pigments because of its high viscosity and density tends to inhomogeneity and agglomeration. This can lead to uneven coloring of the concrete, where z. B. stripes or stains because of the high density can arise. The slurry tends to sediment and Creaming. Because of the poor stability, the slurry be moved. The poor meterability should also be emphasized.
Neues Verfahren:
Es wurde nun in überraschender Weise gefunden, daß in Gegenwart
von Xanthan-Gum Eisenoxid-Pigmenten und einem Dispergiermittel
in Wasser unter Rühren zu stabilen Farbstoffdispersionen
verarbeitet werden.New procedure:
It has now surprisingly been found that iron oxide pigments and a dispersant in water are processed in the presence of xanthan gum with stirring to give stable dye dispersions.
Als Eisenoxid-Pigmente werden in dem erfindungsgemäßen Verfahren natürliche und/oder synthetische Eisenoxid-Pigmente verwendet und Chromoxid-Pigmente.Iron oxide pigments are used in the process according to the invention natural and / or synthetic iron oxide pigments are used and chromium oxide pigments.
Unter Xanthan-Gum versteht man ein Polisaccharid von hohem Molekulargewicht. Die Viskosität beträgt bei mittlerer Scherkraft etwa 1000 mPa · s bei 1% wäßriger Lösung. Xanthan-Gum ist ungiftig.Xanthan gum is a high polisaccharide Molecular weight. The viscosity is medium Shear force about 1000 mPa · s with 1% aqueous solution. Xanthan gum is non-toxic.
Als Dispergiermittel können gebräuchliche nichtionische, anionische, kationische beziehungweise amphotere Tenside mit geeigneter Alkhylkettenlänge Anwendung finden.Common nonionic, anionic, cationic or amphoteric surfactants with a suitable alkyl chain length are used.
Geeignete Dispergiermittel sind z. B. Octyl- beziehungsweise Nonylphenol mit unterschiedlichem Oxethylierungsgrad.Suitable dispersants are e.g. B. octyl or Nonylphenol with different degrees of oxethylation.
Als anionische Dispergiermittel können z. B. sulfatierte langkettige Fettalkohole oder deren Oxethylate Verwendung finden.As anionic dispersants such. B. sulfated long chain fatty alcohols or their oxethylates use Find.
Als kationische Dispergiermittel eignen sich z. B. oxethylierte langkettige Fettamine. Suitable cationic dispersants are, for. B. long chain fatty amines.
Die Herstellung der erfindungsgemäßen Eisenoxid-Pigment Dispersion zum einfärben von Beton, erfolgt im allgemeinen durch turbomischen. Eisenoxid-Pigmente in Wasser in Gegenwart von Xanthan-Gum und einem Dispergiermittel. Eine bevorzugte Ausführungsform meines Patentbegehrens ist wie folgt.The production of the iron oxide pigment according to the invention Dispersion for coloring concrete takes place in general through turbomic. Iron oxide pigments in water in the presence of xanthan gum and a dispersant. A preferred one Embodiment of my patent request is as follows.
In einem Kessel mit Turbomischer versehen wird Wasser Xanthan-Gum und ein Dispergiermittel bei Raumtemperatur vorgelegt. Unter rühren wird nachfolgend Eisenoxid-Pigment eingetragen und etwa 20 bis 30 Minuten gerührt.Water is provided in a boiler with a turbo mixer Xanthan gum and a dispersant at room temperature submitted. Under stirring is subsequently iron oxide pigment registered and stirred for about 20 to 30 minutes.

vom Typ Polycarbonsäure anionisch vorgelegt. Dazu gibt man unter rühren 696 Teile Eisenoxid- Pigmente hinzu. Die Dispersion wird 20 bis 30 Minuten turbiniert. Die so hergestellte Dispersion ist sehr lagerstabil mindestens 6 Monate.of the polycarboxylic acid type anionic submitted. 696 parts of iron oxide are added with stirring. Pigments added. The dispersion is 20 to 30 minutes turbinated. The dispersion produced in this way is very stable on storage at least 6 months.
