Das erfindungsgemäße Verfahren gestattet die Herstellung von Pasten, in denen sich das Aluminiumpulver in Form von flachen Füttern oder Schuppen befindet und damit eine wesent- lioh bessere Deokkraft besitzt als Aluminiumpulver, die mit Stearinsäure behandelt wurden.

They give in liquids homogeneous dispersions without crumbs and lumps and can be used equally well in aqueous and organic solvents

In dem erfindungsgemäßen Verfahren verwendet man handelsübliches Aluminiumpulver. Das Pulver besitzt eine oberflächliche Oxydhaut, die bei der Herstellung entsteht, wird jedoch keiner anderen Behandlung unterworfen als mit Stearinsäure. Die handelsüblichen Pulver enthalten 99 $> Äkiminium und ihre mittlere Korngröße beträgt 60 zu.Commercially available aluminum powder is used in the process according to the invention. The powder has a superficial oxide skin that is created during manufacture, but is not subjected to any treatment other than stearic acid. The commercial powders contain $ 99> Äkiminium and their mean grain size is 60 to.

Man kann unter anderem folgende Mühlen für das erfindungsgemäße Verfahren heranziehen: Kugelmühlen, Hammermühlen, Schwingmühlen usw. Das Mahlen geschieht vorzugsweise bei Raumtemperatur, die Dauer hängt von der Leistungsfähigkeit der Mühle ab. Der Zweck dieser Behandlung ist nicht, die Körngröße der Metallpulver herabzusetzen, sondern jedes Pulverteilchen zu einem Blättchen oder Flitter zu walzen, bei dem die Dicke gegenüber Länge und Breite sehr gering ist.The following mills, among others, can be used for the process according to the invention: ball mills, hammer mills, Vibrating mills, etc. Milling is preferably done at room temperature, the duration depends on the performance of the Mill off. The purpose of this treatment is not to reduce the grain size of the metal powders, but to increase each powder particle to roll a flake or tinsel, in which the thickness is opposite Length and width is very small.

Wenn dies erreicht ist, so dickt man die Paste durch Entfernen des größtmöglichen Teils des Kohlenwasserstoffverdünnungsmittel mit Hilfe von Zentrifugen oder Filtrieren ein. Das ary&er Aluminiumoberfläche fest adsorbierte Copolymer wird bei dieser Behandlung praktisch nicht entfernt, wodurch man eine Paste mit ca. 50 ia Aluminium erhält.When this is achieved, the paste is thickened by removing as much of the hydrocarbon diluent as possible using centrifuges or filtration. The copolymer firmly adsorbed on the ary & er aluminum surface is practically not removed during this treatment, resulting in a paste with approx. 50 ia aluminum.
