Abstract

The method comprises applying a coloured mass to a substrate in the form of a pattern, applying the beads to the still incompletely dried coloured mass, then removing the nonadhering, i.e. surplus, beads, and finally drying the bead-containing mass. The beads are preferably introduced into the mass using heat. By virtue of this method it is possible to obtain products where the beads show optimum reflectivity.

Description

Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Aufbringen von reflektierenden Materialien auf einen Träger unter Verwendung von reflektierenden Perlen.The present invention relates to a method of applying reflective materials to a support using reflective beads.

Seit einiger Zeit ist es bekannt, bestimmte Materialien mit lichtreflektierenden Perlen gemäss bestimmten Mustern zu versehen. Derart mit reflektierenden Materialien versehene Träger finden verschiedene Verwendung, so beispielsweise bei Verkehrs-und Warnschildern, bei Textil- und Kunststoffmaterialien, welche zumindest örtlich mit reflektierenden Zeichen versehen werden.It has been known for some time to provide certain materials with light-reflecting beads according to certain patterns. Carriers provided with reflective materials of this type are used in various ways, for example in traffic and warning signs, in textile and plastic materials which are provided at least locally with reflective signs.

Es wurde dabei üblicherweise so vorgegangen, dass die reflektierenden Perlen mittels eines Bindemittels auf dem Träger bzw. der Unterlage festgemacht wurden, wobei insbesondere bei biegsamen Trägern immer wieder die Schwierigkeit auftauchte, dass sich einzelne Perlen ablösten, und damit nach einiger Zeit der eigentliche Zweck des Anbringens der reflektierenden Materialien nicht mehr erfüllt war.It was usually carried out in such a way that the reflective beads were attached to the carrier or the base by means of a binder, with the difficulty that, in particular with flexible carriers, repeatedly occurring that individual beads detached, and thus after some time the actual purpose of Attaching the reflective materials was no longer met.

Eine weitere Schwierigkeit bestand darin, dass die reflektierenden Perlen dazu neigten, im Bindemittel völlig einzusinken und damit selbstverständlich ihren reflektierenden Wert zu verlieren.Another difficulty was that the reflective beads tended to sink completely into the binder and, of course, lose their reflective value.

Zweck der vorliegenden Erfindung ist es nun, diese Schwierigkeit zu beheben.The purpose of the present invention is now to overcome this difficulty.

Das erfindungsgemässe Verfahren zeichnet sich dadurch aus, dass eine Farbpigmente enthaltende Masse bzw. eine Farbmasse gemäss einem vorbestimmten Muster auf den Träger aufgebracht wird,, dann auf die noch nassse Farbmasse die reflektierenden Perlen aufgebracht und nach dem Anhaften solcher Perlen überschüssige Perlen entfernt werden, und dass schliesslich die Perlen enthaltende Masse getrocknet wird.The process according to the invention is characterized in that a mass containing color pigments or a color mass is applied to the support in accordance with a predetermined pattern, then the reflecting beads are applied to the still wet color mass and excess beads are removed after such beads have adhered, and that the mass containing pearls is finally dried.

Das Aufbringen der Farbmasse entsprechend dem gewünschten Muster erfolgt vorzugsweise im Siebdruckverfahren, wobei die schliesslich auf die auf der Farbmasse aufgebrachten Perlen ein Klarlack, welcher auf die Farbpigmente der Farbmasse abgestimmt ist, aufgebracht wird.The application of the color mass in accordance with the desired pattern is preferably carried out using the screen printing method, the final coat of the pearls applied to the color mass being applied with a clear lacquer which is matched to the color pigments of the color mass.

Bei einem besonders vorteilhaften Vorgehen werden nach dem Entfernen von überschüssigen Perlen die in bzw. an der Farbmasse haftenden Perlen in die Masse eingepresst. Dies erfolgt vorzugsweise unter Anwendung von Wärme, beispielsweise mittels einer Bügelvorrichtung, bei Temperaturen im Bereich von 80 - 130° C.In a particularly advantageous procedure, after the removal of excess beads, the beads adhering in or on the color composition are pressed into the composition. This is preferably done using heat, for example by means of an ironing device, at temperatures in the range from 80 to 130 ° C.

Als Trägermaterialien eignen sich textile Materialien aus natürlichen oder synthetischen Fasern, Papier, Kunststoffe usw.Suitable carrier materials are textile materials made from natural or synthetic fibers, paper, plastics, etc.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles noch etwas näher erläutert.The invention is explained in more detail below using an exemplary embodiment.

Auf einen Träger, zum Beispiel auf einen textilen Träger, wird vorerst im Siebdruckverfahren eine Schicht einer Farbmasse entsprechend einem gewünschten Muster aufgebracht. Als Farbmasse eignen sich dabei insbesondere Zweikomponenten-Textilfarben, wiedieseals lösungsmittelhaltige Siebdruckfarben im Handel erhältlich sind. Solche Farben-haben sehr hohe Deckkraft, brilliante Farbtöne, gute Lichtechtheit und gute Verdruckbarkeit, ferner sehr gute Wasch- und Kochechtheit sowie eine Beständigkeit gegen chemische Reinigung . Solche Farbmassen benötigen keine Fixierung durch Hitze oder Dampf.On a carrier, for example on a textile carrier, a layer of a color mass according to a desired pattern is initially applied using the screen printing method. In particular, two-component textile inks are suitable as the ink, as they are commercially available as solvent-based screen printing inks. Such colors have very high opacity, brilliant colors, good lightfastness and good printability, furthermore very good fastness to washing and cooking, as well as resistance to chemical cleaning. Such color compounds do not need to be fixed by heat or steam.

Solche Farbmassen können durch Zugabe eines Härters (2 - 5 %) rascher zum Trocknen gebracht werden.Such color compounds can be dried more quickly by adding a hardener (2 - 5%).

Nach dem Aufbringen der Farbmasse im Siebdruckverfahren werden bei noch nasser Masse reflektierende Perlen aufgebracht. Dies kann beispielsweise dadurch erfolgen, dass die Perlen über den schräggestellten Träger abgerollt werden. Bei diesem Vorgehen werden überschüssige Perlen über den schräggestellten Träger selbstständig nach unten weiterrollen und können für den Wiedergebrauch.verwendet werden.After applying the color mass in a screen printing process, reflective beads are applied while the mass is still wet. This can be done, for example, by rolling the beads over the inclined support. With this procedure, excess pearls will automatically roll down over the slanted carrier and can be used for reuse.

Als reflektierende Perlen werden ebenfalls solche empfohlen, die im Handel erhältlich sind. Als mittlerer Durchmesser solcher Perlen wird empfohlen, etwa 1 - 177 m . Die Perlen bestehen aus bleifreiem Glas mit hohem Refraktionsindex.Also recommended as reflective beads are those that are commercially available. The average diameter of such beads is recommended, about 1 - 177 m. The beads are made of lead-free glass with a high refractive index.

Nach dem Aufbringen der Perlen.wird das Ganze getrocknet und schliesslich mit einem Klarlack versehen, welcher auf die Farbpigmente der Farbmasse abgestimmt ist, wobei das Aufbringen des Klarlackes entweder auf den ganzen Träger erfolgt, oder ebenfalls mustergemäss mittels der gleichen Schablone wie für den Siebdruck.After applying the pearls, the whole thing is dried and finally provided with a clear varnish, which is matched to the color pigments of the color mass, the clear lacquer being applied either to the entire support or likewise according to the pattern using the same template as for screen printing.

Bei einer Variante dieses Verfahrens werden die Perlen ebenfalls auf die noch nasse Farbmasse aufgebracht, dann jedoch angetrocknet, um schliesslich mittels einer passenden Vorrichtung die Perlen in das Grundmaterial einzupressen. Dieses Ein-oder Anpressen erfolgt vorzugsweise mit Wärme, zum Beispiel etwa bei 80 - 130° C; vorzugsweise bei 100 - 120°C, mittels einer Bügelvorrichtung.In a variant of this method, the beads are also applied to the still wet paint, but are then dried in order to finally press the beads into the base material using a suitable device. This pressing in or pressing is preferably carried out with heat, for example at about 80-130 ° C .; preferably at 100 - 120 ° C, using an ironing device.

Anschliessend wird wiederum der Klarlack aufgebracht, welcher ein sicheres Haften der Perlen garantiert, ohne dass letztere ihre reflektierenden Eigenschaften verlieren.Then the clear lacquer is applied, which guarantees that the pearls adhere securely without the latter losing their reflective properties.
