Description

Verfahren zur Herstellung von thixotropen Kupfer- und Quecksilber-Dispersionen zur Schädlingsbekämpfung Es ist bekannt, Schädlingsbekämpfungsmittel in Form von Pasten herzustellen. Diese enthalten Wirkstoffe, Schutzkolloide, Netzmittel, Emulgatoren und Wasser. Bei längerem Lagern sinken die Wirkstoffe ab; es bildet sich ein Bodensatz, der sich dann meistens weder durch Schütteln noch durch Umrühren mit der darüber stehenden wässerigen Phase wieder vermischen läßt.Process for the production of thixotropic copper and mercury dispersions for pest control It is known to use pesticides in the form of Making pastes. These contain active ingredients, protective colloids, wetting agents and emulsifiers and water. When stored for a long time, the active ingredients sink; a sediment forms, which is then usually neither by shaking nor by stirring with the above standing aqueous phase can be mixed again.

Dieser Übelstand wird um so krasser, je größer das spezifische Gewicht der betreffenden Wirkstoffe ist, z. B. bei Kupfer- und Quecksilberbindungen.The greater the specific weight, the more glaring this disadvantage is the active ingredients in question is, for. B. with copper and mercury bonds.

Man hat zwar versucht, durch Hinzufügen von inerten Stoffen, wie Kaolin, Schlämmkreide u. a., das Sedimentsvolumen zu vergrößern. Ein Absinken läßt sich aber auch dadurch nicht vermeiden.Attempts have been made to add inert substances such as kaolin, Mud chalk, among other things, to increase the sediment volume. A drop can be but also not avoid this.

Es ist bekannt, daß wässerige Schwefeldispersionen durch Beimengung von Aluminiumhydroxyd thixotrop werden. Hierdurch werden die obengenannten Übelstände vermieden. Bei diesem Verfahren werden, gemessen auf das Fertigprodukt, 0,2511/o Aluminiumhydroxyd angewandt.It is known that aqueous sulfur dispersions by admixture of aluminum hydroxide become thixotropic. This eliminates the abovementioned evils avoided. With this method, measured on the finished product, 0.2511 / o Aluminum hydroxide applied.

Das spezifische Gewicht von Kupfer-, Quecksilber-und ähnlichen Verbindungen ist höher als das von Schwefel, so daß nicht anzunehmen war, daß auch bei diesen spezifisch schwereren Wirkstoffen eine Thixotropie mit Hilfe von Aluminiumhydroxyd erreicht werden könnte.The specific gravity of copper, mercury and similar compounds is higher than that of sulfur, so that it was not to be assumed that also with these specifically heavier active ingredients a thixotropy with the help of aluminum hydroxide could be achieved.

Es wurde nun überraschenderweise gefunden, daß man in Verbindung mit Kunstharzdispersionen mit Aluminiumhydroxyd bei diesen spezifisch schwereren Verbindungen ein thixotropes Gemisch erzielen kann, wenn man genügende Mengen Aluminiumhydroxyd zufügt.It has now surprisingly been found that in connection with Synthetic resin dispersions with aluminum hydroxide for these specifically heavier compounds a thixotropic mixture can be achieved if sufficient amounts of aluminum hydroxide are used inflicts.

Es ist bereits bekannt, unter Druck erhitztes Aluminiumhydroxyd als Haftmittel in Pflanzenschutzmitteln zu verwenden. Nicht unter Druck erhitztes Aluminiumhydroxyd haftet nicht.It is already known to use aluminum hydroxide as heated under pressure To use adhesives in pesticides. Aluminum hydroxide not heated under pressure is not liable.

Es ist auch bekannt, mit Hilfe von Alkylenoxyden hergestelltes Aluminiumhydroxyd Pflanzenschutzmitteln zuzusetzen, um die Schwebefähigkeit der Zusatzstoffe in den vom Verbraucher hergestellten Spritzbrühen zu verbessern und um gleichzeitig die Haftfestigkeit zu erhöhen.It is also known that aluminum hydroxide made with the aid of alkylene oxides To add pesticides to the suspending ability of the additives in the to improve the spray liquors produced by the consumer and at the same time to improve the Increase adhesive strength.

Schließlich sind auch bereits thixotrope Pflanzenschutzmittel bekannt, die neben Kupferoxychlorid andere Wirkstoffe oder Streckmittel, die eine Teilchengröße von weniger als 1,5 Mikron haben, und gegebenenfalls Schutzkolloide enthalten. Als Schutzkolloide werden vorgeschlagen: Sulfitcelluloseablauge, Melasse und Dextrin.Finally, thixotropic pesticides are already known, which in addition to copper oxychloride other active ingredients or extenders that have a particle size less than 1.5 microns, and optionally contain protective colloids. as Protective colloids are suggested: sulphite cellulose waste liquor, molasses and dextrin.

Versuche haben, ergeben, daß durch Zusatz dieser Schutzkolloide zu Pasten vorliegender Erfindung, die sämtlich Kunstharzdispersionen enthalten, eine Thixotropie nicht erreicht wird und daß diese Stoffe ein Ausflocken der Kunstharzdispersionen ergeben..Experiments have shown that by adding these protective colloids to Pastes of the present invention, all of which contain synthetic resin dispersions Thixotropy is not achieved and that these substances flocculate the synthetic resin dispersions result..

Weitere Versuche haben ergeben, daß durch Zusatz von Aluminiumhydroxyd zu den Pasten vorliegender Erfindung die Haftfestigkeit erhöht wird, obwohl dieses nicht wie bei den bekannten Verfahren erst unter Druck erhitzt werden oder mit Hilfe von Alkylenoxyden hergestellt werden muß. Diese umständlichen Verfahren sind in Verbindung mit den in der vorliegenden Erfindung benutzten Kunstharzdispersionen nicht notwendig.Further experiments have shown that by adding aluminum hydroxide to the pastes of the present invention, the adhesive strength is increased, although this not be heated under pressure or with the help of the known processes must be prepared from alkylene oxides. These cumbersome procedures are in Compound with the synthetic resin dispersions used in the present invention unnecessary.

Es ist auch bekannt, daß Zusätze zu Kupfer-, Quecksilber- oder ähnlichen fungicid wirkenden Verbindungen die Wirksamkeit dieser Mittel herabsetzen können. Die Freilandversuche aber ergeben, daß z. B. trotz Zugabe von 5 % Aluminiumhydroxyd keinerlei Beeinträchtigung der fungiciden Wirksamkeit eintritt.It is also known that additives to copper, mercury or the like fungicidal compounds can reduce the effectiveness of these agents. The field tests show that z. B. despite the addition of 5% aluminum hydroxide there is no impairment of the fungicidal effectiveness.

Die Höhe der Zugabe von Aluminiumhydroxyd beträgt 1 bis 6%. Es können gegebenenfalls andere fungicide Verbindungen zugemischt werden, wie z. B. Zinkäthylen-bis-dithiocarbamat. Ausführungsbeispiele 1. 30 g Kupferoxychlorid 2 g Phenylquecksilberchlorid 20 g Polyvinylacetatpaste 0,3 g Schutzkolloid 3 g Aluminiumhydroxyd 44,7 g Wasser wurden miteinander innig vermischt. Nach kurzer Zeit erstarrte die flüssige Masse. Ein Absinken der Sedimente trat nicht ein. Durch kurzes Schütteln läßt sich das Gemisch wieder verflüssigen. 2. 30 g Kupferoxydul 4 g Phenylquecksilberacetat " 25 g Polyvinylacetatpaste 0,3 g Schutzkolloid 3 g Aluminiumhydroxyd 37,7 g Wasser wurden innig vermischt. Auch hier erstarrte die flüssige Masse nach kurzer Zeit. Ein Absinken der Sedimente trat nicht ein: Durch kurzes Schütteln läBt sich das Gemisch wieder verflüssigen.The amount of aluminum hydroxide added is 1 to 6%. It can optionally other fungicidal compounds are added, such as. B. zinc ethylene-bis-dithiocarbamate. Working examples 1. 30 g of copper oxychloride, 2 g of phenyl mercury chloride, 20 g Polyvinyl acetate paste 0.3 g protective colloid 3 g aluminum hydroxide 44.7 g water were intimately mixed with each other. After a short time, the liquid mass solidified. A The sediments did not sink. The mixture can be shaken briefly liquefy again. 2. 30 g of copper oxide and 4 g of phenyl mercury acetate "25 g polyvinyl acetate paste 0.3 g protective colloid 3 g aluminum hydroxide 37.7 g water were intimately mixed. Here, too, the liquid mass solidified after a short time. The sediments did not sink: this can be done by shaking them briefly Liquefy the mixture again.
