Description
Verfahren zur Verbesserung der Eigenschaften pulverförmiger Stoffe Es wurde gefunden, dass man die Eigen- sehaftenpulverförmiger Stoffe, insbesondere von Stoffen, die man in der Technik unter dem Begriff Pigmente auf den verschie densten Anwendungsgebieten zum Einsatz bringt, wesentlich verbessern kann, wenn man auf diese Stoffe Gemische aus Salzen saurer organiseher Schwefelsäureabkömmlinge, wie z.
B. Alky lsulfate, Alkylsulfonate oder Alkyl- benzolsulfonate, aufbringt, wie sie aus den sauren Sehwefelsäureabkömmlingen mit nicht flüchtigen, anorganischen Basen, wie z. B. Alkali-, Erdalkali- oder Erdmetallen einer seits und Ammoniak oder organischen Basen anderseits, erhalten werden.
Durch die Behandlung wird die Benetz barkeit der pulverförmigen Stoffe und =ihre Verteilbarkeit in flüssigen, hochviskosen oder plastischen, organischen Materialien er heblich verbessert, weiterhin ihre Schwebe fähigkeit bei der Suspension in Flüssigkeiten sowie ihr Haftvermögen und ihre Schütt- fähigkeit.
Besonders praktisches Interesse besitzen derartig behandelte Pigmente beispielsweise für Lack- und Anstrichstoffe, in denen sie ein ausgezeichnetes Schwebevermögen zeigen, oder als Füllstoffe für Natur- und Kunst kautsehuk, Kautschukregenerate und Kau tsehukersa.tzstoffe.
Pulverförmige Stoffe, die hier in Betracht kommen, können anorganischer oder organi- scher Natur sein, z. B. anorganische Oxyde, Hydroxyde und Salze; wie sie z. B. als Farb- pigmente verwendet werden, wie Ocker, Eisenoxydrot, Bleimennige, Titandioxyd, Zinksulfid, Bariumsulfat, Kalziumcarbonat und dergleichen, ferner Russ, Zinkoxyd, fein disperses Kieselsäureanhydrid, Silicagel, Kal- ziumsilikat- bzw.
Aluminiumsilikatdispersio- nen und dergleichen, wie sie als Füllstoffe für Kautschuk und Kautschu.kregenerate in Betracht kommen. Weiterhin sind zu nennen Pudergrundlagen, wie Talkum, Reismehl, Stärke und dergleichen, Bleicherden, Kaolin, Bimssteinpulver, Tonerde, ferner Aktivkohle, Korkmehl, Holzmehl sowie andere bekannte anorganische oder organische pulverförmige Stoffe.
Die Behandlung dieser pulverförmigen Stoffe mit den Gemischen aus Salzen saurer organischer Schwefelsäureabkömmlinge kann in üblicher Weise erfolgen, indem man z. B. die pulverförmigen Stoffe in Lösungen der Salzgemische in Wasser oder einem organi schen Lösungsmittel einrührt, abtrennt und anschliessend trocknet, oder die Lösungen auf die trockenen Pigmente in geeigneter Weise aufsprüht oder aufnebelt. In geeigneten Fäl len kann man auch die Salzgemisehe durch Vermahlen oder Kollern unmittelbar auf die pulverförmigen Stoffe aufbringen,
wobei beide Komponenten sowohl trocken als auch im angefeuchteten Zustand verwendet werden können. Die Mengen, in denen die Salze saurer organischer Schwefelsäureabkömm- linge auf die pulverförmigen Stoffe aufge bracht werden, hängen von den angewendeten Arbeitsbedingungen und dem jeweiligen Ver- wendungszweck ab. Diese Mengen liegen z. B.
zwischen 0,05-10 % und mehr, vorzugsweise von 0,1--5 oio, auf die pulverförmigen Stoffe berechnet. .

In einer Kugelmühle werden 500 Ge wichtsteile Eisenoxydrot mit 5 Gewichtsteilen eines Sulfatgemisches aus 201/o der Diäthy l- cy clohexylaminsalze eines Alkvlsulfatgemi- sches mit Alkylresten C,1-C11 und 80"/o der Zlagnesiumsalze eines Alkylsulfatgemisches mit Alkylresten Clo-C18 verarbeitet,
bis eine gleichmässige Verteilung des Gemisches auf dem Eisenoxy Brot erzielt ist. Das Eisen oxydrot zeigt. keine Veränderung seines Parb- cha.rakters, ist lagerbeständig und lässt sieh leielit. und lioinogen in Lacke und Anstrich stoffe einarbeiten.
Das Pigment kann z. B. mit einem Ha.rz- esterleinöllaek (1:1) in dem Verhältnis 50 Teile Pigment zu 50 Teils Lack auf einer Trichtermühle eingerieben \.erden. Die An reibung zeigt nach 6monatiger Beobachtungs zeit keinen Bodensatz, sondern höchstens eine Pigmentanreicherung unterhalb des obersten Drittels des Gefässinhaltes, welche sich sehr leicht, wieder in gleichmässige Verteilung bringen lässt. Die Bodensatzbildung, gemessen nach dem Verfahren von Boller-Lichtha.rdt (Farbe und Lack.
Jahrgang 58, Seiten 441 bis 113), war so gering, dass der Prüfkegel bei einer Belastung von nur 9 g den Boden des (*efässes erreichte. Eine Anreibung des glei chen Bindemittels mit. dem gleichen, jedoch irrbehandelten Eisenozydrot, in dem gleichen Mengenverhältnis, ergab nach 6monatiger Beobachtungszeit einen starken, zähen Boden satz, welcher sich nur sehr schwer wieder aufrühren liess.
Diese Anreibung erforderte nach der obigen Prüfmethode eine Kegel belastung von 150 g. um den Boden des Ge fässes zu erreichen.
2. In einem Kollergang .-iirden 500 Ge- wichtsteile Eisenoxydrot mit. 5 Gewichtsteilen einer Lösung behandelt., welche aus 10% Diäthylcyclohexylaminsalz eines Al- kylsuifa.tgemisches mit Alkylresten C4-Ci1 40 /0llagnesiumsalz eines Alk-ylsulfat- gemisches mit.

Aluminum silicate dispersions and the like, as they come into consideration as fillers for rubber and Kautschu.kregenerate. Powder bases such as talc, rice flour, starch and the like, bleaching earth, kaolin, pumice stone powder, clay, also activated carbon, cork flour, wood flour and other known inorganic or organic powdery substances should also be mentioned.
The treatment of these powdery substances with the mixtures of salts of acidic organic sulfuric acid derivatives can be carried out in a conventional manner by z. B. stirs the powdery substances into solutions of the salt mixtures in water or an organic solvent's rule, separates them and then dries them, or spray or mist the solutions onto the dry pigments in a suitable manner. In suitable cases, the salt mixtures can also be applied directly to the powdery substances by grinding or mulling,
Both components can be used both dry and in the moistened state. The quantities in which the salts of acidic organic sulfuric acid derivatives are applied to the powdery substances depend on the working conditions and the respective purpose. These amounts are e.g. B.
between 0.05-10% and more, preferably 0.1-5%, calculated on the powdery substances. .
As organic sulfuric acid derivatives, as they come into consideration in the context of the present invention as components for the salt mixtures used, sulfuric acid esters of aliphatic, cyeloaliphatic and fatty aromatic alcohols and sulfonic acids with aliphatically or aromatically bound sulfonic acid groups can be used, for which the following examples should be mentioned:
Hexylsulfuric esters, ethylsulfuric esters, dodecylsulfuric esters, oleylsulfuric esters or mixtures of alkylsulfuric esters, sulfuric acid esters of naphthenic or resin alcohols, hexylsulphonic acid, cyclohexylsulphonic acid, oetylsulfonic acid,
AlkyIsulfonsäure- o7emiselie, as they are obtained by the action of sulfur dioxide and chlorine on hydrocarbon mixtures such as diesel oil; also octylbenzenesulfonic acid, dodecylbenzenesulfonic acid or other alkylbenzenesulfonic acids or their mixtures, as they are, for.
B. obtained by condensation of unsaturated gasoline hydrocarbons with benzene in the presence of aluminum chloride and subsequent sulfonation, also me tetrahydronaphthalene sulfonic acid and the like.
The alkyl radicals of these sulfuric acid derivatives can also contain heteroatoms, such as oxygen, sulfur or nitrogen, or atomic groups derived therefrom, as well as substituents. Inorganic bases which are used to form the salt mixtures according to the invention are, for example, sodium, potassium, calcium, magnesium, aluminum and the like. As organic bases, primary, secondary or tertiary bases come into consideration, such as.
B. Oetylamine, dioctylamine, cyclohexylamine, diethyyclohexylamine, monomethylaniline, diethylamine, monoethanolamine, triethanolamine, morpholine, piperidine, pyridine, quinoline and the like.
The powdered substances treated with the sulfuric acid derivatives, z. B. Pig ments are suitable for a wide variety of technical fields of application. Apart from the already mentioned production of pigmented lacquers and paints and their use in the rubber industry, they can be used, for example, when mixing powdery opacifiers, coloring agents or fillers into plastics or plastic:
Hassen, in the production of powders for dusting rubber or synthetic resin skins, also in the production of pigment-containing coatings for paper, cardboard and the like or as a filler for paper and cardboard, as a matting agent for artificial silk and shaped structures, as filler, Weighting or finishing agents in the textile industry, etc.
The impregnation process according to the invention is. accordingly applicable in all cases in which it is a matter of improving the surface properties of the powdery substances, increasing their yield in use, improving the stability of their state of distribution and improving the usability of the products made with them. <I> Examples </I> 1.
In a ball mill, 500 parts by weight of red iron oxide are processed with 5 parts by weight of a sulphate mixture of 201 / o of the diethycyclohexylamine salts of an alkyl sulphate mixture with alkyl radicals C, 1-C11 and 80 "/ o of the magnesium salts of an alkyl sulphate mixture with alkyl radicals Clo-C18,
until an even distribution of the mixture on the Eisenoxy bread is achieved. The iron shows oxide red. No change in its Parbcha, it is storable and can be seen easily. and incorporate linearly into varnishes and paints.
The pigment can e.g. B. rubbed in with a Ha.rz- esterleinöllaek (1: 1) in the ratio 50 parts pigment to 50 parts lacquer on a funnel mill. After 6 months of observation, the rubbing shows no sedimentation, but at most an accumulation of pigment below the top third of the contents of the vessel, which can very easily be brought back into an even distribution. The sedimentation, measured according to the Boller-Lichtha.rdt method (paint and varnish.
Volume 58, pages 441 to 113), was so small that the test cone reached the bottom of the container with a load of only 9 g. The same binding agent was rubbed with the same, but mistreated, iron oyster red in the same proportion , after 6 months of observation resulted in a strong, tough soil which was very difficult to stir up again.
According to the above test method, this grinding required a cone load of 150 g. to reach the bottom of the vessel.
2. In a pan mill, 500 parts by weight of red iron oxide are added. Treated 5 parts by weight of a solution, which consists of 10% diethylcyclohexylamine salt of an alkyl sulfate mixture with alkyl radicals C4-Ci1 40 / 0llagnesiumsalz of an alkyl sulfate mixture with.
Alkyl esters C1o-C, 8 40% water 10% hexalin. The accumulation is continued until an even distribution of the alkyl sulfate salt mixture and the evaporation of the water have occurred. The iron oxy drot shows. no change in its color properties and has good distribution and suspension properties in paints.
Grinding of this iron oxide red in a 1: 1 hair ester flake, mixed in a ratio of 50:50, required a cone load of 21 g according to the same test method as Example 1, while the same grinding with untreated pigment in the same ratio required a cone load of 150 g required.
