Description

Verfahren zum Herstellen von wasser- und reibfesten Leimfarbenanstrichen Leimfarben auf pflanzlicher Grundlage enthalten als Bindemittel in Wasser gequollenen Zelleim, ein wasserlösliches Zellulosederivat, wie z. B. Methylzellulose, oder Stärke oder Stärkeabbauprodukte. Auch nach dem Auftrocknen bleiben hiermit hergestellte Leimfarbenanstriche hydrophil und können daher mit Wasser wieder abgewaschen werden.Process for the production of water-resistant and abrasion-resistant glue paint coatings Plant-based distemper paints contain water-swollen binders Cellim, a water-soluble cellulose derivative such as e.g. B. methyl cellulose, or starch or starch breakdown products. Even after they have dried out, they remain Distemper paints are hydrophilic and can therefore be washed off with water.

Es ist bekannt, Pflanzenleim enthaltende Anstrichfarben mit Kunstharzemulsionen zu vermischen; jedoch sind derartige Anstriche nicht absolut wasserbeständig.It is known to paint paints containing vegetable glue with synthetic resin emulsions to mix; however, such paints are not completely water-resistant.

Es wurde nun gefunden, daß man derartige bekannte Leimfarbenanstrichmittel nach dem Auftrag wasserfest und reibfest und damit verschleißfest machen kann, indem man sie mit io bis 2o % bekannter Kunstharzemulsion, z. B. Poyvinylacetat, vermischt und den aufgestrichenen, getrockneten Farbfilm besonders nachbehandelt.It has now been found that such known size-color paints can be used after application can make waterproof and abrasion-resistant and thus wear-resistant by they with io to 2o% known synthetic resin emulsion, z. B. polyvinyl acetate, mixed and the coated, dried paint film is given a special aftertreatment.

Ohne Nachbehandlung ist der aufgetrocknete Leim-Kunstharzemulsionsfarbfilm, ebenso wie der einfache Leimfarbenfilm, weder ausreichend reibfest, noch wasserfest. Beide sind matt. Die aufgetrockneten Teilchen zeigen noch Reste der hydrophilen Bindung vom Emulsionsstadium her.Without any post-treatment, the dried glue-synthetic resin emulsion paint film, just like the simple glue paint film, neither sufficiently rub-resistant nor waterproof. Both are matte. The dried particles still show residues of the hydrophilic ones Binding from the emulsion stage.

Durch die Beimischung der Kunstharzemulsion zur Leimfarbe wirkt erstere als Schutzkolloid, das aber selbst noch nicht völlig wasserfest ist.By adding the synthetic resin emulsion to the glue paint, the former works as a protective colloid, which is not yet completely waterproof itself.

Erfindungsgemäß werden nun derartige Leim-Ku,nstharzemulsionen nach dem Auftrocknen mit einem das Kunstharz lösenden, flüchtigen Lösungsmittel überstrichen oder übersprüht. Dadurch werden die hydrophoben Teilchenhüllen der Kunstharzemulsion im Überzug in dem flüchtigen Lösungsmittel teils angequollen, teils gelöst, wodurch die restliche hydrophile Bindung des Emulgators zerstört und durch hydrophobe Bindung der Filmmasse ersetzt wird.According to the invention, such glue / synthetic resin emulsions are now used drying with a volatile solvent that dissolves the synthetic resin painted over or sprayed over. This creates the hydrophobic particle shells of the synthetic resin emulsion partly swollen in the coating in the volatile solvent, partly dissolved, whereby the remaining hydrophilic bond of the emulsifier is destroyed and by hydrophobic bond the film mass is replaced.

Als geeignete Lösungsmittel zur Nachbehandlung seien z. B. Spiritus, Essigäther, Butylacetat usw. genannt.Suitable solvents for aftertreatment are, for. B. alcohol, Acetic ether, butyl acetate, etc. called.

Die flüchtige Kunstharzlösung verdunstet an der Oberfläche, wodurch sich Kunstharz als hydrophobes Bindemittel, zusammen mit allerfeinsten Festteilchen, in der Oberfläche anreichert und einen dichten, verschleißfesten, harten und doch elastischen, scheuerfesten Film bildet.The volatile synthetic resin solution evaporates on the surface, causing synthetic resin as a hydrophobic binder, together with the finest solid particles, Enriched in the surface and a dense, wear-resistant, hard and yet forms an elastic, abrasion-resistant film.

Wesentlich für den erwünschten Effekt ist die Tiefenwirkung des Lösungsmittels im Film.The depth effect of the solvent is essential for the desired effect in the movie.

Der Farbfilm zeigt jetzt Eierschalenglanz. Nachdem Verfahren der vorliegenden Erfindung kann man die billigen Leimfarbenanstrichmittel nach ihrem Auftrag in hochwertige wasser- und reibfeste Anstrichfilme überführen.The color film now shows eggshell gloss. After the present procedure Invention one can convert the cheap distemper paints into high-quality ones after their application Transfer water- and rub-resistant paint films.
