Description
Verfahren zum Schützen organischer Gläser Bei der Herstelluhg organischer Gläser, derem Versand und späterem Einbau in irgendwelche Geräte u. dgl. ist es notwendig, die Durchsichtigkeit der Kunstharzscheiben dadurch zu sichern, daß man die glasartige Oberfläche durch einen Filmuberzug vor Kratzern und Schrammen schützt und auch vor chemischen Einflüssen durch Lösungsmittel usw. bewahrt. Solche Schutzschichten lassen sich durch Lacke herstellen, die aber den Nachteil haben, daß sie das Glas beim .auftragen anquellen und sich so innig mit der Oberfläche verbinden, daß ein Ablösen eines solchen Schutzfilms unmöglich wird. Gelatine-, Dextrin- und Kaseinüberzüge haften an sich gut, reißen aber nach kurzer Zeit der Tmd,-nung und sind daher unbrauchbar.Method of Protecting Organic Glasses In the manufacture of organic glasses It is glasses, their shipping and later installation in any devices and the like necessary to ensure the transparency of the synthetic resin panes that one the glass-like surface is protected from scratches and scuffs by a film coating and also protected from chemical influences by solvents etc. Such protective layers can be produced by varnishes, but they have the disadvantage that they damage the glass swell when applying and bond so closely with the surface that a Removal of such a protective film becomes impossible. Gelatin, dextrin and casein coatings adhere well to themselves, but tear after a short time and are therefore unusable.
Außerdem hinterlassen sie nach dem Abzielen. bedingt durch ihr größeres-Haftvermögen, immer Reste des Schutzfilms. Man hat aus diesem Grunde vorgezogen, die I(unstgläser mit Papier oder fertigen Folien abzudecken und diese am Rande in geeigneter Weise durch Verkleben zu befestigen. Zu diesem zeitraubenden .Verfahren war man gezwungen, weil es bisher keinen Lack gab, der einen leicht abziehbaren Film ergab, denn die spiegelnde Oberfläche des Kunstglases durfte nicht beeinträchtigt werden.Also, they leave behind after aiming. due to their greater adhesive power, always remnants of the protective film. For this reason it was preferred to use the I (unstgläser to cover with paper or finished foils and to cover them at the edge in a suitable manner to be fixed by gluing. This time-consuming process one was forced to because until now there has been no paint that produced an easily peelable film, because that The reflective surface of the synthetic glass must not be impaired.
Man hat auch Fensterscheiben und Gasmaskenfenster aus Polyvinylalkohol hergestellt bzw. mit einer Außenschicht vonPolyvinylalkohol versehen, um ein Durchschlagen dieser Scheiben zu vermeiden. Diese Polyvinylschicht war aber nicht ablösbar, sondern fest mit dem Kunstglas verbunden. Auch hat man Kraftwagen mit einem -schalldämpfenden überzug versehen, der aus Latex, lösungsmittelhaltigen Anstrichmitteln undFüllmitteln, wie Holzmehl, bestand. Derartige Massen sind aber für das Bestreichen von organischen Gläsern nicht zu verwenden, weil das organische Lösungsmittel sich sofort mit dem organischen Glas verbinden würde. There are also window panes and gas mask windows made of polyvinyl alcohol made or provided with an outer layer of polyvinyl alcohol to prevent strikethrough to avoid these slices. This polyvinyl layer was not removable, but firmly connected to the art glass. You also have vehicles with a soundproofing a coating made of latex, solvent-based paints and fillers, like wood flour. Such masses are for the coating of organic Do not use glasses because the organic solvent dissolves immediately with the organic glass.
Die vorliegende Erfindung betrifft nun die Verwendung eines t'berzuges aus wasserlöslichen Polyvinylderivaten bei organischen Gläsern als leicht abziehbarer vorübergehender Schutzüberzug. The present invention now relates to the use of a cover from water soluble Polyvinyl derivatives in organic glasses as an easily removable temporary protective cover.
Beispiel Film bestehend aus: 90 Teilen Polyvinylalkohol 10 - Glycerin. Example film consisting of: 90 parts of polyvinyl alcohol 10 - glycerine.
Beispiel 2 Film bestehend aus: 80 Teilen Polyvinylalkohol 10 - Methylcellulose 5 - Pentaerythrit 5 - Glycerinersatz. Example 2 Film consisting of: 80 parts of polyvinyl alcohol 10 - methyl cellulose 5 - pentaerythritol 5 - glycerine substitute.
Beispiel 3 Film bestehend aus: 100 Teilen Anlagerungsprodukt von Maleinsäure an Polyvinylalkohol. Example 3 Film consisting of: 100 parts of adduct of Maleic acid to polyvinyl alcohol.
Mit diesen Massen werden organische Gläser beispielsweise von Flugzeugkanzeln usw. bestrichen. Sie ergeben Schutzschichten genügender Beständigkeit. Diese Filme lassen sich außerdem mit Celluloselacken oder constigen Lacken überziehen, wenn es darauf ankommt, die Kunstgläser auch gegen Wettereinflüsse zu schützen. Nach dem Einbau der Organischen Gläser können die Überzüge als Film leicht abgezogen werden, ohne daß die Kunstglasfläche irgendeine Veränderung oder gar Beschädigung erfährt. Zweckmäßig werden die wasserlöslichen Lacke mit einem Weichmacher versetzt, der ebenfalls wasserlöslich sein muß. Solche wasserlöslichen Weichmacher sind Glycerin oder andere höherwertige Alkohole oder Zucker o. dgl.These materials are used to make organic glasses from aircraft cockpits, for example etc. coated. They result in protective layers of sufficient resistance. These films can also be coated with cellulose lacquers or constigenous lacquers, if it is important to protect the synthetic glasses against the weather. To After installing the organic glasses, the coatings can easily be peeled off as a film without affecting the synthetic glass surface in any way or even damaging it learns. The water-soluble paints are expediently mixed with a plasticizer, which must also be soluble in water. Such water-soluble plasticizers are glycerine or other higher alcohol or sugar or the like.
