Die Erfindung hat gefärbte wasserabstoßende Zusammenstellungen zum Ziel, welche in der Form wäßriger Emulsionen vorliegen. Sie werden auf allen Stoffen und insbesondere auf Baustoffen, wie z. B. Backsteinen, Asbest-Zement, Terrakotta, Ziegeln, Tonwaren, Schaumzement, bituminierter Pappe oder Filz, aufgebracht.The invention aims at colored water-repellent compositions which are in the form aqueous emulsions are present. They are used on all fabrics and especially on building materials, such as B. Bricks, asbestos cement, terracotta, bricks, pottery, foam cement, bituminized cardboard or Felt, applied.

Es ist bekannt, daß man beliebige Oberflächen durch Überziehen mit Silikonen wasserabstoßend macht. Der erzeugte Grad der Wasserabstoßung, welcher nach verschiedenen Verfahren gemessen wird, hängt von der Zusammensetzung des oder der Silikone und ihren Mischungen mit anderen Stoffen ab.It is known that any surface can be made water-repellent by coating with silicone power. The degree of water repellency produced, which is measured by various methods depends on the composition of the silicone (s) and their mixtures with others Fabrics.

Auch ist gemäß der belgischen Patentschrift 543 887 bekannt, Baustoffe dadurch wasserabstoßend zu machen, daß man auf sie eine wäßrige Emulsion aufbringt, welche Silikone und ein Acrylharz enthält. Aber weder die Acrylharze allein noch andere, z.B. Polyvinylacetat, Styrolbutadien, Acrylnitril usw., welche bei der vorliegenden Erfindung benutzt werden, noch die gefärbten Pigmente allein sind imstande, in vollkommener Weise Baustoffe wasserabstoßend zu machen. Dies wird jedoch durch die Erfindung erreicht.It is also known from Belgian patent 543 887 that building materials are water-repellent as a result to make that one applies to them an aqueous emulsion which contains silicones and an acrylic resin. But neither the acrylic resins alone nor others, e.g. polyvinyl acetate, styrene butadiene, acrylonitrile etc., which are used in the present invention, nor are the colored pigments alone able to make building materials perfectly water-repellent. However, this is made possible by the Invention achieved.

Die Erfindung besteht in der Verwendung von Silikonemulsionen auf der Grundlage von Alkyl-, Phenyl- oder Alkylphenylsilikonen, Polymerisaten aus ungesättigten Monomeren, organischen Lösungsmitteln, Wasser und Emulgiermitteln mit einem Gehalt an Pigmenten zum Wasserabstoßendmachen von porösen oder faserigen Baustoffen.The invention consists in the use of silicone emulsions based on alkyl, Phenyl or alkylphenyl silicones, polymers made from unsaturated monomers, organic solvents, Water and emulsifying agents containing pigments for rendering water repellent porous or fibrous building materials.

Als Pigmente enthalten diese Emulsionen Aluminium-, Zink- oder Bronzepulver, Eisen-, Chrom- oder Titanoxyde, Chromate, Sulfate oder Sulfide.These emulsions contain aluminum, zinc or bronze powder, iron, chrome or powder as pigments Titanium oxides, chromates, sulfates or sulfides.

Um den technischen Fortschritt der Erfindung gegenüber der belgischen Patentschrift 543 887 nachzuweisen, wurden folgende Vergleichsversuche ausgeführt: In order to prove the technical progress of the invention compared to the Belgian patent specification 543 887, the following comparative tests were carried out:

Auf eine erste Platte aus Schaumzement mit einer Porosität von 12% wurden 50 g/m2 einer Emulsion gemäß der belgischen Patentschrift aus 4% eines Methylphenylsilikones und 26% eines Acrylharzes aufgebracht. Die Wasserabsorption, gemessen nach der Methode A der nachfolgenden Beschreibung, betrug 67,5 g/m2 nach einer Stunde.On a first plate of foam cement with a porosity of 12%, 50 g / m 2 of an emulsion according to the Belgian patent of 4% of a methylphenyl silicone and 26% of an acrylic resin were applied. The water absorption, measured by method A of the description below, was 67.5 g / m 2 after one hour.

Das nachstehende Beispiel 1 wurde wiederholt unter Auftragung von 62,5 g/m2 einer Emulsion, die durch Vermischung von 65 g einer Acrylharzemulsion (4O°/oig), 30 g Chromoxyd und 40 g einer Me-Wasserabstoßende pigmentierte Überzüge für
poröse oder faserige Baustoffe
Example 1 below was repeated with the application of 62.5 g / m 2 of an emulsion made by mixing 65 g of an acrylic resin emulsion (40%), 30 g of chromium oxide and 40 g of a Me water-repellent pigmented coatings for
porous or fibrous building materials

thylphenylsilikonemulsion (15°/oig) erhalten wurde, auf eine zweite Schaumzementplatte mit einer Porosität von 12%. Die Wasserabsorption, gemessen nach der gleichen Methode betrug 37,5 g/m2 nach einer Stunde.ethylphenyl silicone emulsion (15%) was obtained on a second foam cement board with a porosity of 12%. The water absorption, measured by the same method, was 37.5 g / m 2 after one hour.

Diese Ergebnisse zeigen deutlieh, daß die erfindungsgemäßen Emulsionen — außer einem gewissen dekorativen Effekt — eine erheblich verstärkte wasserabstoßende Wirkung aufweisen.These results clearly show that the invention Emulsions - apart from a certain decorative effect - a considerably strengthened one have a water-repellent effect.
