Description
Die vorliegende Erfindung betrifft eine neue wäßrige Suspension von mindestens einem feinteiligen Pulver aus Ton.The present invention relates to a new aqueous suspension of at least a fine powder of clay.
Wäßrige Suspensionen von Ton oder tonhaltigen Pulvermischungen werden bei der Herstellung von Gegenständen aus Keramik, Lacken und Papier sowie als Bohrspül- und Absorptionsmittel, z. B. in der Lebensmittelindustrie, verwendet. Zudem finden diese wäßrigen Suspensionen auch bei der Aufarbeitung von Tonen aus mineralischen Vorkommen Anwendung.Aqueous suspensions of clay or clay-containing powder mixtures are used in the Manufacture of objects from ceramics, lacquers and paper as well as Drilling fluid and absorbent, e.g. B. used in the food industry. In addition, these aqueous suspensions are also found in the processing of clays from mineral deposits application.
Bekanntermaßen werden wäßrige Suspensionen von Ton oder tonhaltigen Pulver mischungen durch Zugabe von Verflüssigern stabilisiert und so vor Koagulation und Flockung geschützt. Hohe Pulverkonzentrationen bewirken aufgrund der Pulver-Pulver-Wechselwirkung eine hohe Viskosität. Verflüssiger mindern nach verschiedenen Mechanismen eben diese Wechselwirkungen und bewirken eine Herabsetzung der Viskosität. Hochviskose Suspensionen weisen eine Reihe von Problemen bei der Verwendung auf, wie beispielsweise Verlaufsstörungen in Streichfarben oder Blasenbildung bei der Keramikherstellung.As is known, aqueous suspensions of clay or clay-containing powder Mixtures stabilized by adding plasticizers and thus before coagulation and flocculation protected. Due to the high powder concentrations Powder-powder interaction high viscosity. Reduce the condenser different mechanisms just these interactions and cause one Reduced viscosity. Highly viscous suspensions have a number of Problems with use, such as history disorders in Brush colors or blistering in ceramic production.
Eine effektive Wirkungsweise der Verflüssiger wird bislang jedoch erst bei höheren Verflüssigerkonzentrationen erreicht. Dies ist jedoch weder aus ökologi schen noch aus ökonomischen Gesichtspunkten sinnvoll. Insbesondere bei der Her stellung von Keramikgegenständen ist die Entfernung der organischen Spaltpro dukte beim Brennen von Keramiken, die organische Verflüssiger enthalten, auf wendig. So far, however, an effective mode of operation of the condensers has only become apparent higher condenser concentrations reached. However, this is not ecological still make sense from an economic point of view. Especially with the Her The position of ceramic objects is the removal of the organic fission products when firing ceramics containing organic plasticizers agile.
Dadurch ist ein großer Bedarf an stark wirksamen Verflüssigern vorhanden, vor allem an denen, die bereits in geringen Mengen in der Lage sind stabile wäßrige Suspensionen aus Ton oder tonhaltigen Pulvermischungen niedriger Viskosität zu bilden.As a result, there is a great need for highly effective condensers especially on those who are able to produce stable aqueous solutions in small quantities Suspensions of clay or clay-containing powder mixtures of low viscosity form.
Bekannte Verflüssiger sind Natriumsilikate, Natriumpolyphosphate sowie verschie dene organische Polyelektrolyte, wie Alginate, Pektine, Carboxymethylcellulose oder Polyacrylate ("Dispersants" in Kirk-Othmer Encyclopedia of Chemical Technology, 3. Auflage, Vol. 7 (1979) S. 844-848). Aus US 4 186 028 ist bereits die Anwendung von Phosphonocarbonsäuren zur Herstellung stabiler Pigmentsuspensionen beschrieben. Bekannte anorganische Verflüssiger erreichen in der Regel erst ab Mengen von 0,3 Gew.-%, bezogen auf die Pulvermenge, ihre volle Wirksamkeit.Known plasticizers are sodium silicates, sodium polyphosphates and various organic polyelectrolytes such as alginates, pectins, carboxymethyl cellulose or polyacrylates ("dispersants" in Kirk-Othmer Encyclopedia of Chemical Technology, 3rd edition, vol. 7 (1979) pp. 844-848). From US 4 186 028 is already the use of phosphonocarboxylic acids to produce more stable Pigment suspensions described. Known inorganic plasticizers reach in generally only from quantities of 0.3% by weight, based on the quantity of powder, their full effectiveness.
Aufgabe der vorliegenden Erfindung war daher die Bereitstellung stabiler, niedrig viskoser Suspensionen von mindestens einem feinteiligem Pulver aus Ton in Wasser, die nur geringe Mengen organischen Verflüssiger enthalten.The object of the present invention was therefore to provide stable, low viscous suspensions of at least one fine powder of clay in Water that contains only a small amount of organic plasticizers.
Es wurde nun gefunden, daß eine wäßrige Suspension aus mindestens einem feinteiligen Pulver aus Ton, mindestens einem anorganischen Verflüssiger und mindestens einer Phosphonocarbonsäure besonders niedrige Viskositäten aufweisen. Diese niedrigen Viskositätswerte werden dabei schon bei sehr geringen Mengen der erfindungsgemäßen Phosphonocarbonsäuren erreicht. Die Wirkung der erfindungsgemäßen Kombination aus anorganischen Verflüssigern und Phosphonocarbonsäuren ist dabei weitaus stärker als die bei getrenntem Einsatz nur einer der beiden Komponenten. Diese Wirksamkeit wird auch bei erfindungsgemäßem Einsatz der entsprechenden Alkali salzen von Phos phonocarbonsäuren, nur in deutlich größeren Mengen, erreicht.It has now been found that an aqueous suspension of at least one finely divided powder of clay, at least one inorganic plasticizer and at least one phosphonocarboxylic acid has particularly low viscosities exhibit. These low viscosity values are already very low Amounts of the phosphonocarboxylic acids according to the invention reached. The effect of combination of inorganic liquefiers and Phosphonocarboxylic acids are much stronger than those when used separately just one of the two components. This effectiveness is also at inventive use of the corresponding alkali salts of Phos phonocarboxylic acids, only in significantly larger amounts.
