Description

Einbettungsmittel für Leuchtfarben Die bisher bekannten Leuchtfarben sind in ihrer praktischen Brauchbarkeit außerordentlich- beschränkt, weil sie durch die Atmosphärilien verhältnismäßig leicht zersetzt werden. Besonders die auf der Basis der Erdalkalisulfide und -oxyde a'ufgebautenhochwertigen Leuchtfarben verwittern sehr leicht und unterliegen schon. bei Gegenwart von Feuchtigkeit teinerZersetzung. Aber auch die Zinksulfid-Leuchtfarben sind schlecht haltbar. Um diesem -Übelstand abzuhelfen, - wurde schon _ vielfach versucht, die Leuchtfärben durch 'Überzüge von Lacken und durch Einbettungsmittel, wie z. B. Wachs u. dgl., wetterbeständiger und haltbarer zu machen. Diese Aufgebe. wird erschwert dadurch, daß die b:etreff!eriden Substanzen außerdem noch wasserhelI; durchsichtig und weitgehend durchlässig . für den besonders stank erregenden. kurzwelligen Anteil des Lichtes sein müssen.Embedding medium for luminous colors The previously known luminous colors are extraordinarily limited in their practical usefulness because they are through the atmospheres are relatively easily decomposed. Especially the one on the The basis of the alkaline earth sulfides and oxides of the high-quality luminous paints built-up weather very easy and already succumb. decomposition in the presence of moisture. But the zinc sulfide fluorescent paints are also poorly durable. To this evil to remedy this - many attempts have already been made to remove the luminous colors by means of coatings of paints and embedding agents, such as. B. wax, etc., more weather-resistant and to make it more durable. This surrender. is made more difficult by the fact that the b: etreff! suffer Substances in addition still water helI; transparent and largely permeable. for the particularly stinking one. short-wave portion of the light must be.

Der heute auf dem Markt käufliche Leuchtfarbenlack besteht aus- seiner Auflösung `von Dämarharz in Terpentinöl. Auch manche andere, z. B:. aus Phexiol und einem, Aldehyd aufgebaute Kondensätiönsprodtkte oder Acrylsäureesterpölymerisationsprodukte sind schon in Vorschlag gebracht worden, ebenso wie unverseifbäre -Harzrückstände.. Alle diese bisher bekanntgewordenen Substanzen sind aber :entweder von vornherein nicht wetterbeständig, oder sie wirken auf die sehr reaktions'; fähigen Sulfide chemisch hin,. zumal sie meist geringe Mengen von Säuren oder verseifbaren Bestandteilen (enthalten. Andere Schutzstoffe wieder sind gefärbt und deswegen unbrauchbar, weil sie für den wirksamsten Teil der. Strahlen undurchlässig sind.The fluorescent paint that is available on the market today consists of his Dissolution of demar resin in turpentine oil. Also some others, e.g. B: from phexiol and an aldehyde-based condensation product or acrylic acid ester polymerisation product have already been proposed, as well as unsaponifiable resin residues .. However, all of these previously known substances are: either from the outset not weather resistant, or they act on the very reactive '; capable sulfides chemically out. especially since they usually contain small amounts of acids or saponifiable components (Contained. Other protective substances are colored and therefore unusable because them for the most effective part of the. Rays are opaque.

Es wurde nun gefunden, daß Polystyrol, seine .Homologen und Derivate, sofern diese reine Köhlenwass.erstoffe ;sind, den hier gestellten Anforderungen vollkommen @entsprechen. Als solche Produkte kommen z. B, neben Polystyrol selbst die Polymerisations produkte des Methylstyrols, Äthylstyrolsy Vinylnaphthalins, Vinyltetrahydronaphthalins u, dgl. in Frage. Die Produkte dieser Klasse enthalten keine verseifbaren und sauren Bestandteile. Man kann aus ihnen z. B. streichbare Lacke, @evtl. unter Zusatz von Weichmachungsmitteln, herstellen, die wasserklar ,erhärten,- gut lichtdurchlässig sind und außerdem einen vorzüglichen Schutz gegen -die -Atmosphärilien bieten, da sie von Feuchtigkeit usw. nicht angegriffen werden. Mit den sulfidischen Leuchtfarben selbst reagieren sie in keiner Weise. Ein weiterer Vorteil dieser Produkte ist ihr außerordentlich hohes Lichtbrechungsvermö,gen und ihre bisherunbekannt gewesene Eigenschaft, daß sie das Nachleuchten der eingebetteten Phosphore- wesentlich verstärken -Auch fluoreszierende . rund phosphoreszie-', rende Formstücke lassen sich leicht herstellen durch Eintragen von Leuchtfarben. in schmelz-bzw. gießbares Polystyrol, seine Homologen und Derivate oder durch Spritzen, Walzen oder Verpressen von in der Wärme formbaren Kondensationsprodukten der obenerwähnten Art. Ebenso lassen sich auch entsprechende Schichten auf vorgeformte Tragkörper aufbringen. Auch durch Einrühren von Leuchtfarben in Styrol und seine Homologen bzw. Derivate unter anschließender Polymerisation kann man zu selbstleuchtenden Formkörpern und Anstrichen gelangen. Selbstleuchtende Folien und Filme können natürlich ebenfalls durch Gießen oder Spritzen hergestellt werden.It has now been found that polystyrene, its homologues and derivatives, insofar as these are pure hydrocarbons, the requirements set out here completely @comply with. Such products come e.g. B, next to polystyrene itself the polymerization products of methylstyrene, ethylstyrolsy vinylnaphthalene, Vinyl tetrahydronaphthalene and the like. The products in this class contain no saponifiable and acidic components. You can z. B. paintable Paints, @evtl. with the addition of plasticizers, produce that are water-clear , harden, - are well translucent and also provide excellent protection against -the -Atmosphärilien offer, as they are not attacked by moisture, etc. They do not react in any way with the sulphidic fluorescent colors themselves. Another The advantage of these products is their extremely high refractive power, gen and their previously unknown been property that it has the afterglow of the embedded phosphors- significantly amplify -Also fluorescent. around Phosphoreszie- ', rende shaped pieces can be easily produced by entering of luminous colors. in melting or. castable polystyrene, its homologues and derivatives or by spraying, rolling or pressing of condensation products that can be shaped under heat of the type mentioned above. Likewise, corresponding layers can also be applied to preformed Apply support body. Also by stirring fluorescent paints into styrene and its Homologues or derivatives with subsequent polymerization can become self-luminous Moldings and paints get there. Luminous foils and films can of course can also be made by casting or spraying.
