Abstract

Water-gel (I) comprises 0.1-5 (pref. 0.6-0.7)% polyacrylic acid with m.wt. of up to 4,000,000 and is neutralised with sodium hydroxide to a pH of 6.5-7.5. (I) is pref. reacted with other salt-formers, e.g. alkali metals, alkaline earth metals, NH4OH or amines. (I) is not neutralised. Other gel builders are used e.g. cellulose and its derivs. (esp. carboxymethyl cellulose), alginate, agar-agar, gelatin, pectin, polysaccharide, silicic acid or montmorillonite. USE/ADVANTAGE - (I) is used in plant nutrition (claimed). Plants can be fed for up to four weeks using (I).

Description

Gegenstand der vorliegenden Erfindung ist ein wäßriges Gel, welches Polyacrylsäure und dessen Salze enthält. Zweck der Erfindung ist es, Zimmerpflanzen über einen längeren Zeitraum mit Wasser zu versorgen.The present invention is an aqueous Gel containing polyacrylic acid and its salts. The purpose of the invention is to houseplants on a to provide water for a longer period of time.

Es ist bekannt, daß die Versorgung von Zimmerpflanzen während der Abwesenheit der Eigentümer problematisch ist.It is known that the supply of houseplants during the absence of owners problematic is.

Die vorliegende Erfindung ermöglicht eine sichere Ver­ sorgung von Zimmerpflanzen bis zu vier Wochen, ggf. auch länger.The present invention enables a secure Ver houseplants up to four weeks, if necessary also longer.

Die Erfindung hat sich somit die Aufgabe gestellt, daß sich Pflanzen über einen längeren Zeitraum selbst mit Wasser versorgen können.The invention has thus set itself the task that Plants themselves over a longer period of time Supply water.

Diese Aufgabe wird dadurch gelöst, daß Polyacrylsäure als Gelbildner in Wasser aufgeschlossen wird. Derartige Lösungen sind stark sauer, pH 3, aber bereits in dieser Form als Wasserspender geeignet.This object is achieved in that polyacrylic acid as gelling agent is digested in water. such Solutions are highly acidic, pH 3, but already in this Shape suitable as a water dispenser.

Durch Neutralisation und Umwandlung in die Salze der Polyacrylsäure, wird eine wesentlich höhere Viskosität erzielt und ein Gel erzeugt, welches sich insbesondere eignet.By neutralization and conversion to the salts of Polyacrylic acid, will have a much higher viscosity achieved and produces a gel, which in particular suitable.

Die erfindungsgemäße Aufgabe kann auch durch eine Viel­ zahl anderer, mit Wasser gelbildende Substanzen erzielt werden, wie z. B. Cellulose und deren Derivate, Alginate, Agar-Agar usw.The object of the invention can also by a lot number of other water-gelling substances be such. B. cellulose and its derivatives, alginates, Agar-agar etc.

Agar-Agar wäre erfindungsgemäß besonders geeignet, da es bereits bei einer Konzentration von 0,1-0,2% ein anwendbares Gel bildet. Da aber Cellulose, Alginate und Agar-Agar microbiologisch sehr anfällig sind, sich mit übler Geruchsbildung zersetzen und unkonserviert nicht lange haltbar sind, kaum geeignet. Konservierungsmittel würden aber Bodenmicroben zerstören und somit die Pflanze schädigen.Agar-agar would be particularly suitable according to the invention, since it already at a concentration of 0.1-0.2% forms applicable gel. But since cellulose, alginates and Agar agar microbiologically are very susceptible to deal with Odorless decompose and not preserved long lasting, hardly suitable. preservative but would destroy soil microbes and thus the plant damage.

Die erfindungsgemäß verwendete Acrylsäure und deren Salze sind microbiologisch wesentlich stabiler und un­ konserviert haltbar und dadurch für den vorgesehenen Verwendungszweck besonders geeignet.The acrylic acid used in the invention and their Salts are microbiologically much more stable and un Preserves and preserves for the intended Use especially suitable.

In den nachfolgenden Beispielen sind zwei erfindungs­ gemäße Rezepturen aufgeführt, die sich gut bewährt haben. In the following examples are two fiction, appropriate recipes listed that have worked well.

Es handelt sich um ein bereits anwendbares Gel.It is an already applicable gel.

Dieses Gel eignet sich besonders für Pflanzen mit einem hohen Wasserbedarf.This gel is especially suitable for plants with one high water requirement.

Ein so hergestelltes Gel ist annähernd neutral. Es ist jedoch auch möglich, die Polyacrylsäure nicht vollstän­ dig zu neutralisieren/versalzen, oder mit alkalischem Überschuß zu arbeiten. pH-Werte von 3-9 sind erfindungs­ gemäß anwendbar. Im besonderen ist ein pH-Wert von 6,5- 7,5 geeignet.A gel made in this way is almost neutral. It is but also possible, the polyacrylic acid is not complete to neutralize / salinate, or with alkaline Over work. pH values of 3-9 are fiction according to applicable. In particular, a pH of 6.5 7.5 suitable.

Ein derart hergestellte Gel wird zur Pflanzenversorgung großflächig auf die Blumenerde verteilt. Allein der Kon­ takt Erde/Gel bewirkt, daß Wasser in die Erde abgegeben wird. Zudem wird das Natriumsalz der Polyacrylsäure lang­ sam von den Bodenmicroben zersetzt.A gel prepared in this way becomes a plant supply distributed over a large area on the potting soil. Only the Kon Earth / gel causes water to be released into the earth becomes. In addition, the sodium salt of polyacrylic acid becomes long sam decomposed by the soil microbes.

Derart behandelte Pflanzen können sich bis zu vier Wochen selbst mit Wasser versorgen. Für eine mittelgroße Topf­ pflanze werden ca. 100 g. Gel pro Woche benötigt. Bei einer Versorgung über einen langeren Zeitraum ist es not­ wendig, in den Topf eine Art Kragen anzubringen, damit entsprechend mehr Gel aufgetragen werden kann.Such treated plants can last up to four weeks even supply with water. For a medium sized pot Plant will be about 100 g. Gel needed per week. at A supply over a long period of time is necessary manoeuvrable to put a kind of collar in the pot so that correspondingly more gel can be applied.
