Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines kristallinen, ionenaustauschenden Alkalialuminiumsilikates mit hydrophiler Oberfläche durch inniges Vermischen des Alkalialuminiumsilikates mit einer wäßrigen Lösung eines hydrophilierenden Agens sowie anschließendem Trocknen und Aufmahlen sowie die Verwendung des erfindungsgemäß hergestellten kristaliinen, ionenaustauschenden Alkalialuminiumsilikates mit hydrophiler Oberfläche in Wasch-, Spül- und Reinigungsmitteln. The invention relates to a process for the production of a crystalline, ion-exchanging alkali aluminum silicate with a hydrophilic surface by intimately mixing the alkali aluminum silicate with an aqueous one Solution of a hydrophilizing agent and subsequent drying and grinding as well as the use of the crystalline, ion-exchanging alkali aluminum silicate produced according to the invention hydrophilic surface in detergents, dishwashing detergents and cleaning agents.
In einer prioritätsälteren Anmeldung (P 24 47 021.1) wird der Einsatz von kationenaustauschenden Natriumaluminiumsilikaten in Wasch-, Spül- und Reinigungsmitteln vorgeschlagen.In an earlier application (P 24 47 021.1) the use of cation-exchanging sodium aluminum silicates proposed in detergents, dishwashing detergents and cleaning agents.
Einer Verwendung von kationenaustauschenden Alkaliaiuminiumsilikaten in einem relativ großen Anteil an der gesamten Wasch-, Spül- und Reinigungsmischung steht jedoch entgegen, daß derartige Mittel nach dem Einstreuen oder Einspülen in Wasser relativ lange unbenetzt bleiben und gegebenenfalls zusammenklumpen oder auf der Wasseroberfläche schwimmen.Use of cation-exchanging alkali aluminum silicates in a relatively large proportion of the total washing, rinsing and cleaning mixture however, it is opposed to the fact that such agents remain unwetted for a relatively long time after being sprinkled or rinsed into water stay and possibly clump together or float on the surface of the water.
Durch diesen »Sägemehleffekt« tritt eine verzögerte Wirksamkeit derartiger Wasch- und Reinigungsmittel ein, d. h., insbesondere bei Verwendung in automatischen Waschmaschinen werden die Mittel nicht mehr für die volle im Waschprogramm zur Verfügung stehende Zeit ausgenützt. Vor allem aber können durch den »Sägemehleffekt« gewisse Anteile derartiger Wasch-, Spül- oder Reinigungsmittel auf Basis ionenaustauschender Aluminiumsilikate für den Waschprozeß überhaupt verloren gehen, indem sie sich an den Grenzflächen Waschflotte-Luft-Behälter ablagern.This “sawdust effect” results in a delayed effectiveness of such detergents and cleaning agents a, d. that is, especially when used in automatic washing machines, the agents no longer work for the full available in the wash program Exploited time. Above all, however, the »sawdust effect« can cause certain proportions of such washing, Dishwashing detergents or cleaning agents based on ion-exchanging aluminum silicates for the washing process in general are lost by being deposited on the washing liquor-air container interfaces.
Um die bekannte Fähigkeit der ionenaustauschenden Aluminiumsilikate zur Bindung von Ca2+- und Mg2+-Ionen zum Aufbau phosphatarmer Wasch-, Spül- und Reinigungsmittel besser nutzen zu können, ist es notwendig, ihre Benetzbarkeit durch Wasser zu verbessern, ihre Oberfläche also zu hydrophilieren.In order to better utilize the known ability of ion-exchanging aluminum silicates to bind Ca 2+ and Mg 2+ ions to build up low-phosphate detergents, dishwashing detergents and cleaning agents, it is necessary to improve their wettability with water, i.e. to improve their surface hydrophilize.
In der DE-OS 23 54 432 wird ein Verfahren zur Verbessert ig der Benetzbarkeit von natürlichen oder synthetischen Zeolithen vorgeschlagen, nach welchem man die Zeolithe unter guter Durchmischung mit einer wäßrigen Lösung mindestens einer polyelektrolytischen Polycarbonsäure und/oder mindestens eines ganz oder teilweise neutralisierten Polycarboxylats bei Temperaturen zumischen 0 und 100° mindestens 5 Minuten lang behandelt, trocknet und aufmahltIn DE-OS 23 54 432 a method for improving the wettability of natural or synthetic Zeolites proposed, after which one the zeolites with thorough mixing with an aqueous Solution of at least one polyelectrolytic polycarboxylic acid and / or at least one whole or partially neutralized polycarboxylate at temperatures 0 and 100 ° for at least 5 minutes treats, dries and grinds
