Description

Entrostungspaste In der Patentanmeldung M 30164 VI/48d ist eine Entrostungspaste beschrieben, bestehend aus einem verseifbaren Öl oder einer in eine Seife überführbaren Fettsäure, oder einem hochviskosen oder festen Reduktionsprodukt von Fettsäuren bis einschließlich zu den entsprechenden Fettalkoholen als Verdickungsmittel, emulgiert in wäßriger Phosphorsäure.Rust removal paste In the patent application M 30164 VI / 48d there is a rust removal paste described, consisting of a saponifiable oil or one that can be converted into a soap Fatty acid, or a highly viscous or solid reduction product of fatty acids up to and including the corresponding fatty alcohols as thickeners, emulsified in aqueous phosphoric acid.

Es ist auch bereits eine Entrostungspaste vorgeschlagen, die aus Polyvinylalkohol oder Polyacrylsäure in wäßriger Phosphorsäure besteht.A rust removal paste made from polyvinyl alcohol has also already been proposed or polyacrylic acid in aqueous phosphoric acid.

Es wurde nun gefunden, daß man nicht nur Pasten, die als Verdickungsmittel eines dieser aufgeführten Verdickungsmittel enthalten, einsetzen kann, sondern auch Pasten, die mehrere dieser genannten, zu einer abwaschbaren Paste führenden Verdickungsmittel enthalten. Die Verwendung eines Gemisches aus mindestens zwei Komponenten, nämlich verseifbaren Ölen und/oder in eine Seife überführbaren Fettsäuren und/oder hochviskosen bzw. festen Reduktionsprodukten von Fettsäuren, insbesondere Fettalkoholen, und/oder Polyvinylalkohol, hat den Vorteil, daß man durch Kombination verschiedener Mittel die Konsistenz der Entrostungspasten leichter variieren und einstellen kann.It has now been found that you can not only use pastes as thickeners contain one of these listed thickeners, but also Pastes containing several of the aforementioned thickeners resulting in a washable paste contain. The use of a mixture of at least two components, namely saponifiable oils and / or fatty acids which can be converted into a soap and / or highly viscous ones or solid reduction products of fatty acids, in particular fatty alcohols, and / or Polyvinyl alcohol has the advantage that you can use a combination of different agents the consistency of the rust removal pastes can be varied and adjusted more easily.

Im folgenden seien zwei Beispiele für solche Entrostungspasten angegeben: Beispiel 1 7 % Fettalkohol, 7 °/o Polyvinylalkohol, 50°% Phosphorsäure (D = 1,58), 5 °/o Emulgator, Rest Wasser. Beispiel 2 5 % Stearylalkohol, 8 % Stearinsäure, 50°% Phosphorsäure (D = 1,58), 3 °/o Emulgator, 1 % Methylzellulose, Rest Wasser.Two examples of such derusting pastes are given below: Example 1 7% fatty alcohol, 7% polyvinyl alcohol, 50% phosphoric acid (D = 1.58), 5% emulsifier, remainder water. Example 2 5% stearyl alcohol, 8% stearic acid, 50% Phosphoric acid (D = 1.58), 3% emulsifier, 1% methyl cellulose, the remainder water.
