Description
Verfahren zur Herstellung besonders hellfarbiger und nichtabsetzender Bitumenlackfarben Es ist eine Tatsache, daß sogenannte Bitumen-und Asphaltlacke zwar bis zu einem gewissen Grade angefärbt werden können, daß aber hierbei im allgemeinen nur Eisenoxydrot, reine Chromgrünpigmente undAluminiumpulver ausreichendeFärbekraft besitzen, um sich gegenüber der schwarzen Eigenfarbe der Bitumina genügend durchzusetzen und daß es vor allem kaum möglich ist, selbst mit dem farbkräftigen Titandioxyd auch nur einigermaßen helle und neutrale Grautöne zu erzielen.Process for the production of particularly light-colored and non-settling Bitumen paints It is a fact that so-called bitumen and asphalt paints can be stained to a certain extent, but that in general only iron oxide red, pure chrome green pigments and aluminum powder have sufficient coloring power own in order to prevail sufficiently against the black inherent color of the bitumens and that above all it is hardly possible, even with the strongly colored titanium dioxide to achieve even somewhat light and neutral gray tones.
Es wurde nun gefunden, daß esdurch einfacheZugabe verhältniismäßig geringer Mengen von Polyvinyläthe,rn, wie insbesondere von Polyvinyläthyläther, vor dem Anreiben gelingt, die verschiedensten und vor allem nichtabsetzenden Bitumenilackfarben. von' ungewöhnlich hellem und neutralem Farbcharakter zu erzeugen, welche den entsprechenden polyvinylätherfreien Bitumenlackfarben deutlich überlegen sind. Ähnlichen Effekt erhält man selbstverständl,ich auch, wenn man zu einer der bisher üblichen Bitumenfarben den Polyvi.nyläther nachträglich zusetzt und dann gut durchrührt. Lediglich als Beispiel, d. h. also als eine, den Schutzumfang dieser Erfindung durch die Zufälligkeit ihrer prozentualen: Zusammensetzung keineswegs einschränkende Ausführungsform sei folgende Arbeitsvorschrift für eine hellmittelgraueBitumenlackfarbe gegeben: 32 Teile eines Bitumens mit einem Schmelzpunkt zwischen 6o und i25° werden in 33 Teilen Lösungsmittel (Testbenzin oder Benzolkohlenwasserstoffen) gelöst und mit etwa 5 bis io Teilen Polyvinyläthyläther versetzt. Dann verdünnt man mit 25 bis 35 Teilen zusätzlichem Testbenzin und reih f schließlich in bekannter Weise 6o bis 75 Teile Titandioxyd o. dgl. Weißpigment ein, wobei man eine hochwertige, leicht thixotrope, aber ausgezeichnet verstreichbare Lackfarbe von feucht-, zunächst beigegrauer Färbung erhält, die beim Trocknen innerhalb 30 'bis 6o Minuten einen mehr oder minder seidenglänzenden Anstrichfilm von schönem hellmittelgrauem Farbton ergibt. In ähnlicher Weise lassen sich mit gelben, blauen, roten oder grünen Pigmentfarbstoffen entsprechend gefärl>te.-"nstriclimittel herstellen.It has now been found that by simple addition it is proportionate small amounts of polyvinyl ether, such as in particular polyvinyl ethyl ether, Before rubbing on, the most varied and, above all, non-settling bitumen lacquer paints succeed. of 'to produce an unusually light and neutral color character, which corresponds to the polyvinyl ether-free bitumen paints are clearly superior. Similar effect You get it, of course, and so do I, if you go to one of the previously common bitumen paints add the polyvinyl ether afterwards and stir well. Merely as Example, d. H. So as one, the scope of this invention by chance their percentage: composition is by no means a limiting embodiment The following working instructions are given for a light medium gray bitumen paint color: 32 Parts of a bitumen with a melting point between 6o and i25 ° are divided into 33 parts Solvent (white spirit or benzene hydrocarbons) dissolved and mixed with about 5 up to 10 parts polyvinyl ethyl ether offset. Then you dilute with 25 to 35 parts of additional white spirit and finally row f in a known manner 6o to 75 parts of titanium dioxide or the like. White pigment, with a high quality, slightly thixotropic, but excellently spreadable paint from moist, initially beige-gray color, which on drying takes 30 'to 60 minutes more or less silk-gloss paint film of a beautiful light medium gray color results. Similarly, yellow, blue, red, or green pigment dyes can be used Manufacture correspondingly dyed nstriclim remedies.
