Description

Verfahren zur Herstellung von Überzügen Es ist bekannt, Harze, Pech, Wachse, Polymerisationsprodukte u. dgl. zu dispergieren. Die Dispergierung soll derart vorgenommen werden, daB die kalten und geschmolzenen Harze mit Wasser in Gegenwart von Alkalien in Kolloidmühlen behandelt werden. Im Gegensatz dazu werden die nach dem vorliegenden Verfahren zur Herstellung von Überzügen verwandten Emulsionen dadurch hergestellt, daß man Lösungen von Polyvinylverbindungen in Wasser emulgiert, wobei man ohne die Anwendung von Spezialapparaturen, wie schnellaufenden Kolloidmühlen, auskommt.Process for the production of coatings It is known to use resins, pitch, To disperse waxes, polymerization products and the like. The dispersion should be made in such a way that the cold and molten resins are mixed with water Presence of alkalis can be treated in colloid mills. In contrast, will the emulsions used in the present process for the preparation of coatings produced by emulsifying solutions of polyvinyl compounds in water, without the use of special equipment, such as high-speed colloid mills, gets by.

Es wurde gefunden, daB man haltbare Überzüge auf Materialien aller Art dadurch herstellen kann, wenn man wäBrige Suspensionen von Polymerisationsprodukten von Poly v inylverbindungen auf die zu überziehenden Gegenstände aufträgt. Als solche kommen z. B. in Frage Zementsteine, Ton- und Backsteine, Sandsteine, Gipswände, Verputzmassen aller Art, Holzverkleidungen, die verschiedensten Papiersorten, wie z. B. Papierpappe, Stoffe, gepreBte Kunststoffe, wie z. B. Vulkanfiber, Leder usw. Durch Polieren können die Überzüge noch weiter verdichtet werden. Man kann aber auch auf poröse Überzüge hinarbeiten, wie dies z. $ beim Leder erforderlich ist. Auch können die Lacke mit Füllstoffen und Farbpigmenten versetzt werden.It has been found that durable coatings can be used on all materials Art can be produced by using aqueous suspensions of polymerization products of polyvinyl compounds on the objects to be coated. As such come z. B. in question cement stones, clay and bricks, sandstones, plaster walls, Plastering compounds of all kinds, wood cladding, the most diverse types of paper, such as z. B. paper board, fabrics, pressed plastics, such as B. Vulcanized fiber, leather, etc. The coatings can be further compressed by polishing. But you can also work towards porous coatings, as z. $ is required for leather. The paints can also be mixed with fillers and color pigments.

Zur Herstellung einer derartigen wäßrigen Suspension --mulgiert man z. B. eine Polyvinylacetatlösung durch Eintropfen in Wasser mit oder ohne Zusatz emulgierender Schutzkolloide und vermengt die Emulsion hierauf mit Substrat, oder man reibt die Lösung zuvor mit dem Substrat an und emulgiert hierauf in Wasser.To produce such an aqueous suspension, one emulsifies z. B. a polyvinyl acetate solution by dripping in water with or without additives emulsifying protective colloids and then mixes the emulsion with substrate, or the solution is rubbed with the substrate beforehand and then emulsified in water.

Beispiel Man läßt 29o Gewichtsteile Wasser unter kräftigem Rühren langsam in 400 Gewichtsteile einer 25°/oigen Lösung von Polyvinylacetat in Alkohol einlaufen. Es entsteht eine Emulsion, die unmittelbar oder nach Verreibung mit Pigmenten als überzugslack verwendbar ist.Example 29o parts by weight of water are left with vigorous stirring slowly in 400 parts by weight of a 25% solution of polyvinyl acetate in alcohol come in. An emulsion is created, which is immediately or after trituration with pigments can be used as a top coat.

Als Pigmente kommen sowohl anorganische Farbstoffe, wie z. B. Mennige, Eisenoxyd, Metall- oder Bronzepulver, Zinkweiß, Lithopone usw., als auch organische Farbstoffe in Betracht.Both inorganic dyes, such as. B. red lead, Iron oxide, metal or bronze powder, zinc white, lithopone, etc., as well as organic ones Dyes into consideration.

Die Lacke können sowohl durch Aufstreichen als auch durch Aufspritzen aufgetragen werden. Durch dieses Verfahren wird nicht nur ein weitgehender Oberflächenschutz, sondern auch gleichzeitig eine Verschönerung der Oberfläche erreicht. Z. B. kann auf diese Weise ülaerzogenes Papier mit Vorteil, als abwaschbare Tapeten benutzt werden.The paints can be applied by brushing or spraying on be applied. This process not only provides extensive surface protection, but also at the same time a beautification of the surface is achieved. E.g. can Paper educated in this way can be used to advantage as washable wallpaper will.
