Description
Anstrich von hydrophobe Grundierungen aufweisenden Oberflächen Bei der Verwendung hydrophober Stoffe in Anstrichinitteln und Schutzanstrichen, die wasserabweisend sind, ergeben sich dadurch Schwierigkeiten, daß sich auf wasserabweisenden Anstrichen ein zweiter Anstrich zur Verstärkung des bestehenden oder bei der Erneuerung des Anstriches nicht oder nur sehr schwer aufbringen läßt, da der zweite Anstrich auf dem ersten nicht mehr haftet oder nicht oder nur langsam trocknet.Painting of surfaces with hydrophobic primers the use of hydrophobic substances in paints and protective coatings that Are water-repellent, difficulties arise in that on water-repellent Paint a second coat to reinforce the existing one or when renovating of the paint can not be applied or only with great difficulty, since the second coat at first no longer adheres or not or only dries slowly.
Diese Nachteile sollen durch vorliegende Erfindung behoben werden, indem den durch Zusatz hydrophober Stoffe, wie Mineralöle, Paraffine, Wachse, Silikonöle u. dgl., allein oder in Mischung miteinander wasserabweisend gemachten Anstrichinitteln auch noch hydrophile bzw. einulgierende Substanzen, wie fettsaure Salze, Amine. sulfonierte Fett- und Mineralöle, zugesetzt werden.These disadvantages are intended to be remedied by the present invention, by adding hydrophobic substances such as mineral oils, paraffins, waxes, silicone oils and the like, alone or in admixture with one another, paints made water-repellent also hydrophilic or emulsifying substances such as fatty acid salts, amines. sulfonated fatty and mineral oils.
Die Verwendung hydrophiler Substanzen zur Verbesserung der Haftfähigkeit eines hyd-rophoben Anstriches auf einem ersten hydropho-ben Anstrich scheint sich überlegungsgemäß zunächst zii verbieten, da durch einen solchen Zusatz die Aufhebung der wasserabweisenden Eigenschaften zu befürchten ist. Cberraschenderweise zeigt sich jedoch richtige Dosierung, die von Fall zu Fall experimentell festgestellt «-erden inuß. vorausgesetzt, daß bei gleichzeitiger Anwesenheit von hydrophilen und hydrophoben Stoffen die wasserabweisende Wirkung einerseits erhalten bleibt, während die Schwierigkeiten, die beim Auftragen in der Haftung eines zweiten Anstriches bestanden, gänzlich behoben werden.The use of hydrophilic substances to improve adhesiveness a hydrophobic coating on a first hydrophobic coating appears to be initially forbidding zii, as such an addition would result in the repeal the water-repellent properties is to be feared. Surprisingly shows however, correct dosage, which has been experimentally established on a case-by-case basis «-Erden inuss. provided that with the simultaneous presence of hydrophilic and hydrophobic substances, on the one hand, the water-repellent effect is retained, while the difficulties encountered when applying in the adhesion of a second coat passed, must be completely remedied.
In der Literatur sind Anstrichdispersionen b ekanntgeivorden. die sowohl hvdrophile als auch hydrophol e Stoffe enthalten. Der zahlenmäßige Anteil dieser Stoffe an der Gesamtdispersion berücksichtigt jedoch in keiner Weise die dein Erfindungsgegenstand zugrunde liegenden Verhältnisse. Mit jenen Anstrichd ispersionen beabsichtigt man auch keineswegs die Lösung des Problems einer Verbesserung der Haftfähigkeit eines zweiten hydr:ophoben Anstriches.Paint dispersions are known in the literature. the contain both hydrophilic and hydrophilic substances. The numerical share However, these substances in the total dispersion do not take into account the the circumstances underlying your subject matter of the invention. With those painting dispersions one also by no means intends to solve the problem of improving the Adhesiveness of a second hydr: ophobic coating.
Mit Erfolg kann das Verfahren gemäß der Erfindung jedoch ausgeübt werden, wenn sich die Zusätze im Rahmen der folgenden Beispiele halten: 1. In die wässerige Dispersion eines Polvvinylchloridswerden 2 bis 20% einer 30%igen Lösung eines Hartparaffins in Benzin und 1 bis 5% einer wässerigen Lösung eines Salzes einer höheren Fettsäure einemtilgiert. 2. Die wässerige Dispersion eines Alkydharzes wird mit 3% einer 25%igen Lösung von Ceresin in Toluol, mit 1% einer 10%igen Silikonöllösung und 1,5°/o eines sulfonierten Mineralöls versetzt.However, the method according to the invention can be practiced with success if the additions are within the scope of the following examples: 1. In the aqueous dispersion of a polyvinyl chloride becomes 2 to 20% of a 30% solution of a hard paraffin in gasoline and 1 to 5% of an aqueous solution of a salt a higher fatty acid. 2. The aqueous dispersion of an alkyd resin is with 3% of a 25% solution of ceresin in toluene, with 1% of a 10% solution of silicone oil and 1.5% of a sulfonated mineral oil are added.
3. Zu einer Casein-bl-I3arz-Dispersion gibt inanunter Rühren 101/a einer 30%igen Lösung von Ozokerit in Benzin und 30/u Türkischrotöl.3. Add 101 / a to a casein-bl-I3arz dispersion with stirring a 30% solution of ozokerite in gasoline and 30 / u Turkish red oil.
Die Dispersionen der Beispiele 1 bis 3 können pigmentiert oder unpigmentiert als Anstrichinittel Verwendung finden; die Pigmente können hydrophober und/oder hydrophiler Natur sein. Ebenso können Verdünnungsmittel hydrophober und/oder hydrophiler Natur verwandt werden.The dispersions of Examples 1 to 3 can be pigmented or unpigmented are used as paints; the pigments can be more hydrophobic and / or be hydrophilic in nature. Diluents can also be more hydrophobic and / or more hydrophilic Related to nature.
Als Bindemittel können schließlich auch solche verwendet werden, die besonders glänzende Deckschichten ergeben.Finally, binders that can also be used are those which result in particularly glossy top layers.
