Description

Verf ahren zur Erzeugung von Phosphatzementschichten c auf Werkstoffoberflächen Zusatz zum Patent (872 2991 Die Erfindung betrifft eine weitere Ausgestaltung des Patentes 872 299. Nach dem im Patent 872 299 aufgeführten Verfahren wird auf die Werkstoffoberfläche ein Pulvergemisch des Dreistoffsystems Ca0-AI.03--S'02M't verdünnter wäßriger Phosphorsäure oder mit einer stark sauren wäßrigen Metallphosphatlösung zu einem Brei angerührt, in dünner Schicht auf die Werkstoffoberfläche aufgetragen.Method for producing phosphate cement layers c on material surfaces Addition to the patent (872 2991 The invention relates to a further embodiment of the patent 872 299. According to the method listed in the patent 872 299 , a powder mixture of the three-substance system Ca0-AI.03 - S '02M't dilute aqueous phosphoric acid or mixed with a strongly acidic aqueous metal phosphate solution to a paste, applied in a thin layer to the surface of the material.

Es wurde nun gefunden, daß das Verfahren für bestimmte Zwecke dadurch verbessert werden kann, daß man die Zusammensetzung des Pulvergemisches Ca0-A1203--Si0, insofern ändert, daß an Stelle von Caleiumoxyd Magnesiumoxyd in äquivalenter Menge verwandt wird. Nach einer besonderen Ausführungsforni der Erfindung kann dem Pulvergemisch des Dreistoffsystems Mg0-A1,0,--Si0, feinstes Talkummehl zugemischt werden. Die unter Zusatz von Talkum hergestellten Oberflächenbehandlungsmittel sind besonders geeignet, auf Metalloberflächen Schutzschichten zu erzeugen, die gegen klebrigen Gummi abweisend sind. Diese Schichten eignen sich daher als ideale Trennmittel zwischen Metallen und Gummi bzw. Kautschuk. Auch Pulvergemische von Magnesia und Talkum mit verdünnter wäßriger Phosphorsäurelösung zu einem Brei angerührt sind geeignet. Es hat sich gezeigt, daß bei Verwendung von Pulvergemischen, die Mg0 enthalten, die Phosphorsäuremenge zu dem Pulvergemisch so abgestännit werden muß, daß die mit verdünnter Phosphorsäure fertig angerührte Mischung einen p#I-Wert von 2,5 bis 3 hat, besonders wenn Nichteisenmetalle behandelt werden sollen. Bei der Behandlung von Eisenoberflächen kann der p.H-Wert niedriger sein, besonders wenn das Eisen leicht mit Rost bedeckt ist.It has now been found that the process can be improved for certain purposes by changing the composition of the powder mixture Ca0-A1203-Si0 to the extent that magnesium oxide is used in an equivalent amount instead of calcium oxide. According to a special embodiment of the invention, very fine talcum powder can be added to the powder mixture of the three-component system Mg0-A1.0, -Si0. The surface treatment agents produced with the addition of talc are particularly suitable for producing protective layers on metal surfaces which are repellent to sticky rubber. These layers are therefore ideal as separating agents between metals and rubber or caoutchouc. Powder mixtures of magnesia and talc, mixed with dilute aqueous phosphoric acid solution to form a paste, are also suitable. It has been shown that when powder mixtures containing MgO are used, the amount of phosphoric acid in the powder mixture must be balanced in such a way that the mixture mixed with dilute phosphoric acid has a p # I value of 2.5 to 3 , especially when non-ferrous metals should be treated. When treating iron surfaces, the pH can be lower, especially if the iron is lightly covered with rust.

Anwendungsbeispiele i. als Trennmittel für Gummi: 21 g eines Pulvergemisches, bestehend aus 14 9 feingemahlenem Talkum und 7 g feingemahlenem Magnesiumoxyd, werden mit ioo g einer 250/,igen wäßrigen Phosphorsäurelösung zu einer Suspension angerührt. Die Suspension wird mit einem Pinsel dünn auf die Metalloberfläche aufgetragen.Application examples i. As a release agent for rubber: 21 g of a powder mixture consisting of 14 9 finely ground talc and 7 g of finely ground magnesium oxide are mixed with 100 g of a 250% aqueous phosphoric acid solution to form a suspension. The suspension is applied thinly to the metal surface with a brush.

2. als Isolierschicht bei 8oo': 21 g des Pulvergeinisches Mg0-A1,0,-Si0" das ini Verhältnis 33 : 45 : 22 gemischt ist, werden mit ioo g einer 250/,igen wäßrigen Phosphorsäurelösung zu einer Suspension angerührt. Die Suspension wird mit einem Pinsel dünn auf die Metalloberfläche aufgetragen.2.
