Abstract

In a process for the production of extendable colloidal aggregates for soil-improving agents from finely ground clay materials (e.g. bentonite) by incorporating known org. additives which seve directly to promote aggregation (e.g. urea of methylcellulose), there are also added organic cpds. having an effect on the water-stability of the aggregates. One group of pref. water-stabilising additives is hydrocarbon cpds. with free charges or functional groups such as e.g. unsaturated alcohols or monocarboxylic acids, these cpds. being used in an amount of ca 2-5%. Another pref. group of water-stabilising additives is saccharides (e.g. sucrose), these being used in an amount of ca 5-15%. The additives impart lasting hydrophilisation to the colloidal aggregates, so that soil treated with teh new soil improving agens have long-lasting water-retaining properties. It is advantageous to use relatively high concentrations of saccharides because these undergo rapid microbial reaction to form new waterstable, hydrophilic structures.

Description

Beschreibung im Sinne von § 3 der Anmeldebestimmungen für Patente Bezeichnung der Erfindung: Verfahren zur Herstellung von Bodenverbesserungsmitteln aus feingemahlenem, natürlichen Tonmaterial und technischen, organischen Zuschlägen Während das in der Anmeldung P 23 50 799.5 beschriebene Verfahren die Anwendung der Mittelanteile unmittelbar auf den Boden betrifft, wird hier die Anwendung kolloidbildender Mittel auf streufähige, lagerfähige und sackbare Bodenverbesserungsmittel beschrieben. Die jetzige Neuanmeldung beschreibt desweiteren neue Erkenntnisse zu der Anmeldung P 23 50 798.4, soweit sich diese auf natürliche Silikate beziehen.Description according to § 3 of the registration requirements for patents Title of the invention: Process for the production of soil improvers made of finely ground, natural clay material and technical, organic additives While the method described in the application P 23 50 799.5 the application of the middle parts directly on the soil, the application becomes colloid-forming here Means on spreadable, storable and sackable soil improvers described. The current new registration also describes new findings about the registration P 23 50 798.4, insofar as these relate to natural silicates.

Es wurde gefunden, daß die Produkte einer Aggregierung von Tonmaterial wie z. B. Bentonit, die Mithilfe von Harnstoff und Methylcellulose sehr einfach durchgeführt werden kann mit weiteren organischen Zuschlägen, die sehr geringe Anteile einnehmen können, zu einer dauerhaften Hydrophilierung wasserarmer Bodensysteme beitragen können.It has been found that the products of aggregation of clay material such as B. Bentonite, the help of urea and methyl cellulose very easy Can be done with other organic additives that have very low proportions can take, to a permanent hydrophilization of water-poor soil systems can contribute.

Es genügen z. B. Zuschläge von 2 % Acrylsäure oder ähnlichen, Fadenkolloide bildenden Säuren, um eine sehr ausdauernde Krümelart zu schaffen, die für lange Zeit die mehrfache Wassermenge bindet wie sandige Bodenaggregate.It suffices z. B. Additions of 2% acrylic acid or similar, thread colloids forming acids to create a very persistent type of crumb that lasts for a long time Time the multiple amount of water binds like sandy soil aggregates.

Wählt man anstelle der Kohlenwasserstoffverbindungen mit einer oder mehreren funktionellen Gruppen Sacharide, so ist es vorteilhaft, deren Anteil gegenüber dem Grundgemisch zu erhöhen, weil bei einer Beteiligung der Sacharide eine sehr schnelle bakterielle Umsetzung eintritt und die Mikrobenausscheidungen zu neuen wasserstabilen, hydrophilen Strukturen beitragen.If you choose instead of the hydrocarbon compounds with an or several functional groups saccharides, so it is advantageous to compare their proportion to increase the basic mixture, because with a participation of the saccharides a very rapid bacterial conversion occurs and the microbe excretions to contribute to new water-stable, hydrophilic structures.

Beispiel 1: 80 Gewichtsteile feinvermahlener Alkali- oder Erdalkalibentonit werden mit je 10 Gewichtsteilen Tylose oder ähnlichen methylierten Alkalicellulusen und 10 Gewichtsteilen Harnstoff vermischt und unter sehr feiner Verteilung mit geringen Wassermengen besprüht, wobei die Aggregierung erfolgt. Auch eine Variierung der Anteile ist zulässig.Example 1: 80 parts by weight of finely ground alkali or alkaline earth bentonite are each with 10 parts by weight of Tylose or similar methylated alkali cells and 10 parts by weight of urea mixed and very finely divided with little Sprayed amounts of water, the aggregation taking place. Also a variation of the Shares are permitted.

Beispiel 2: Bei der gleichen Zusammensetzung wie zu 1 werden 2 % Harnstoff weniger unter Zuschlag von 2 % Acrylsäure oder ähnlichen Stabilisatoren verwendet. Eine Variierung der Anteile ist möglich.Example 2: With the same composition as in 1, 2% are urea less with an addition of 2% acrylic acid or similar stabilizers. The proportions can be varied.

Beispiel 3: 80 Gewichtsteile Bentonit oder anderes aufweitbares Tonmaterial wird mit 10 % Zucker oder Rohzucker und 10 % Methylcellulose wie oben versetzt und in gleicher Weise wie im Beispiel Nr. 1 mit Wasser behandelt.Example 3: 80 parts by weight of bentonite or other expandable clay material is mixed with 10% sugar or raw sugar and 10% methyl cellulose as above and treated in the same way as in Example No. 1 with water.

Beispiel 4: Gegenüber dem Beispiel Nr. 3 z. B. Ermäßigung des Tonanteils auf 70 % und Zuschlag von je iO % Rohzucker, Harnstoff und Methylcellulose.Example 4: Compared to example no. B. Reduction of the sound component to 70% and a surcharge of 10% each of raw sugar, urea and methyl cellulose.
