Description

Anstrichmittel In den letzten Jahren haben sich in steigendem Maße wäßrige Dispersionen von Phthalsäure-Glycerin-bzw. Phthalsäure-Fettsäure-Glycerin-Harzen als Anstrichmittel eingebürgert, ferner hat man hierfür schon wäßrige Dispersionen von polymeren Acrylsäureestern unter Zusatz geeigneter Pigmente und Füllstoffe empfohlen.Paints in recent years have become increasingly popular aqueous dispersions of phthalic acid-glycerol or. Phthalic Acid-Fatty Acid-Glycerin Resins Naturalized as a paint, and aqueous dispersions are already available for this purpose of polymeric acrylic acid esters with the addition of suitable pigments and fillers recommended.

Es wurde nun gefunden, daß wäßrige Dispersionen, die als Bindemittel plastifiziertes, polymeres Styrol sowie die erforderlichen Füllstoffe, Farbstoffe, Emulgatoren usw, enthalten, vorzügliche Anstrichmittel darstellen. Wäßrige Dispersionen von plastifiziertem, polymerem Styrol können z. B. erhalten werden, wenn man einen in üblicher Weise durch Emulsionspolymerisation hergestellten Polystyrollatex in die wäßrlge Dispersion eines geeigneten Weichmachungsmittels einrührt, wobei die Menge des letzten, Zoo bis 2oo%, sich nach dem angestrebten Effekt richtet, oder wenn man in beliebiger Weise polymerisiertes Styrol in Gegenwart eines Weichmachungsmittels in einem organischen Lösungsmittel löst und aus der Lösung unter Zusatz von Emulgatoren eine Emulsion in Wasser herstellt. Geeignete Weichmachungsmittel für das polymere Styrol sind z. B. Phthalsäureester, niederpolymere flüssige Styrole usw., Kondensationsprodukte gemäß dem Verfahren nach Patent 833 645.It has now been found that aqueous dispersions that act as binders plasticized, polymeric styrene as well as the necessary fillers, dyes, Emulsifiers, etc., are excellent paints. Aqueous dispersions of plasticized, polymeric styrene can, for. B. obtained if you have a Polystyrene latex produced in the usual way by emulsion polymerization in stir in the aqueous dispersion of a suitable plasticizer, the Amount of the last, zoo up to 2oo%, depends on the desired effect, or when in any way polymerized styrene in the presence of a plasticizer Dissolves in an organic solvent and out of solution with the addition of emulsifiers creates an emulsion in water. Suitable plasticizers for the polymer Styrene are e.g. B. phthalic acid esters, low polymer liquid styrenes, etc., condensation products according to the method of patent 833,645.

Zur Stabilisierung derartiger Suspensionen verwendet man mit Vorteil kleine Mengen von Verdickungsmitteln, wie polyacrylsaures Natrium, etwa 0,3 bis 30/0, bezogen auf die Filmbestandteile. Vorteilhaft bereitet man möglichst konzentrierte Dispersionen, die beispielsweise bis zu 6o% filmbildende Bestandteile enthalten können. Für den Gebrauch rührt man die erforderliche Menge Pigment usw. ein und stellt mit Wasser auf die gewünschte Konsistenz. Mit den erhaltenen Farben lassen sich wetterbeständige, schnell trocknende und festhaftende Anstriche auf Holz, Metall, Zement und Verputz herstellen. Beispiel Z Man mischt im Kneter 4o Teile des Kondensationsproduktes aus Äthylmethylketon, Formaldehyd und Methylalhepten, hergestellt gemäß den Angaben des Patentes 833 645, mit 3°/0 leinölsaurem Natrium und o,50,7" polyacrylsaurem Natrium. Darauf setzt man Zoo Teile einer durch Emulsionspolymerisation hergestellten wäßrigen Dispersion von Polystyrol, enthaltend 6o Teile Polystyrol, zu und rührt zum Schluß so viel von einem Pigment, z. B. Zinkweiß, Kreide oder Ocker, ein, daß eine streichfertige Masse entsteht. Man erhält eine für Innenanstriche auf Verputz geeignete Farbe.To stabilize such suspensions, it is advantageous to use small amounts of thickeners, such as sodium polyacrylate, about 0.3 to 30/0, based on the film constituents. It is advantageous to prepare dispersions which are as concentrated as possible and which can contain, for example, up to 60% of film-forming constituents. For use, stir in the required amount of pigment, etc. and adjust to the desired consistency with water. The paints obtained can be used to produce weather-resistant, quick-drying and firmly adhering paints on wood, metal, cement and plaster. EXAMPLE Z 40 parts of the condensation product of ethyl methyl ketone, formaldehyde and methyl alheptene, prepared according to the specifications of patent 833 645, are mixed in a kneader with 3% sodium linoleum and 0.50.7 "polyacrylic sodium An aqueous dispersion of polystyrene produced by emulsion polymerization, containing 60 parts of polystyrene, is added and finally enough pigment, e.g. zinc white, chalk or ocher, is stirred in to produce a ready-to-paint composition .

Beispiel 2 In eine Lösung von 2o Teilen des Einwirkungsproduktes von 20 Mol Äthylenoxyd auf Z Mol Octadecylalkohol in 2o Teilen Wasser werden unter Rühren Zoo Teile niederpolymeres, flüssiges Styrol, hergestellt z. B. durch Leiten von Styrol bei erhöhter Temperatur in der flüssigen Phase über unlösliche Katalysatoren sauren Charakters, eingetragen. Die erhaltene Emulsion wird sodann mit Zoo Teilen eines Pigmentes, z. B. Lithopone, in der Kugelmühle angerieben, wobei noch 2 Teile polyacrylsaures Natrium, gelöst. in 60 eilen Wasser, zur Verbesserung der Pigmentverträglichkeit zugesetzt werden können. In die erhaltene Masse werden 4oo Teile einer 25°/oigen Polystyrolemulsion (K-Wert = Z40), die'z. B. durch Emulsionspölymerisation erhalten wurde, eingerührt, und man erhält ein Anstrichmittel, das glänzende, wasserfeste, witterungsbeständige und lichtechte Anstriche auf Holz; Metall und Verputz gibt.Example 2 In a solution of 20 parts of the product of action of 20 moles of ethylene oxide to Z moles of octadecyl alcohol in 2o parts of water are stirred Zoo parts low polymer, liquid styrene, manufactured e.g. B. by directing Styrene at elevated temperature in the liquid phase over insoluble catalysts acidic character, registered. The resulting emulsion is then zoo parts a pigment, e.g. B. Lithopone, rubbed in the ball mill, with 2 parts polyacrylic acid sodium, dissolved. in 60 hours of water to improve pigment compatibility can be added. 400 parts of a 25% strength are added to the mass obtained Polystyrene emulsion (K value = Z40), the'z. B. obtained by emulsion polymerization was stirred in, and you get a paint that is glossy, waterproof, weather-resistant and lightfast paints on wood; Metal and plaster there.

Beispiel 3 Man löst Zoo Teile Polystyrol (K-Wert = 8o) und Zoo Teile niederpolymeres flüssiges Styrol in der zur Lösung erforderlichen Menge Toluol und trägt die erhaltene Lösung unter Rühren in eine Lösung von 20 Teilen des Einwirkungsproduktes von 20 Mol Äthylenoxyd auf Z Mol Octadecylalkohol in 3oo Teile Wasser ein. Man erhält ein Anstrichmittel, dem zur Verbesserung der Pigmentverträglichkeit noch geringe Mengen polyacrylsaures Natrium zugesetzt werden können, das zur Herstellung von Anstrichen auf Holz, Metall und Verputz verwendet werden kann.Example 3 Zoo parts polystyrene (K value = 8o) and zoo parts are dissolved low-polymer liquid styrene in the amount required for solution and toluene carries the resulting solution into a solution of 20 parts of the action product while stirring from 20 moles of ethylene oxide to Z moles of octadecyl alcohol in 300 parts of water. You get a paint that is still low to improve pigment compatibility Amounts of sodium polyacrylic acid can be added to produce Paints on wood, metal and plaster can be used.
