Description
Infrarotreflektierende, feuerfeste Überzüge bildende Massen Es ist bekannt, Holz oder sonstige brennbare Gegenstände durch einen Schutzüberzug aus unbrennbaren Materialien, insbesondere Magnesiten oder sonstigen Gemischen aus Magnesiumoxyd und Magnesiumchlorid zu schützen. Desgleichen lassen sich zu diesem Zweck Materialien auf reiner Silikatbasis verwenden und weiterhin Materialien, die ein pulverförmiges mineralisches Bindemittel darstellen und welche durch innige Mischung von kalk- und tonhaltigen Rohmaterialien, darauffolgendes Brennen bis zur Sinterung und starke Zerkleinerung gewonnen werden.Infrared reflecting refractory coatings forming masses It is known, wood or other flammable objects with a protective coating incombustible materials, especially magnesites or other mixtures of magnesium oxide and magnesium chloride to protect. Materials can also be used for this purpose Use on a pure silicate basis and continue to use materials that are powdery represent mineral binders and which by intimate mixing of lime and clay-containing raw materials, subsequent firing until sintering and strong Comminution can be obtained.
Trotz des feuerfesten Schutzüberzuges besteht eine erhebliche Gefährdung der zu schützenden Teile dadurch, daß eine akkumulierende Wirkung von Infrarotstrahlung eintreten kann. Bedingt ist diese wärmeakkumulierende Wirkung in den feuerfesten Schutzüberzügen durch die verminderte Reflexion bis zu Wellenlängen von 10 #t und darüber. Wenn zudem farbige oder sogar dunkle Schutzüberzüge gewünscht werden, dann wurden bisher Pigmente ohne Berücksichtigung der Infrarotreflexion verwendet, und es hat sich gezeigt, daß die meisten Pigmente in der Hauptsache Infrarotabsorber darstellen. Ein guter feuerfester Schutzüberzug muß sich deshalb a) durch große Beständigkeit bei hohen Temperaturen, b) durch geringe Wärmeleitung und c) durch hervorragende Infrarotreflexion auszeichnen.Despite the fireproof protective coating, there is a considerable risk the parts to be protected by having an accumulating effect of infrared radiation can occur. This heat-accumulating effect is conditional in the refractories Protective coatings due to the reduced reflection up to wavelengths of 10 #t and about that. If colored or even dark protective coatings are required, then pigments were previously used without taking infrared reflection into account, and it has been found that most pigments are mainly infrared absorbers represent. A good fireproof protective coating must therefore a) be large Resistance to high temperatures, b) through low heat conduction and c) through excellent infrared reflection.
Erfindungsgemäß werden daher Mischkristalle aus Sulfiden und/oder Seleniden undioder Telluriden der Metalle der II. Gruppe des Periodischen Systems, gegebenenfalls zusammen mit anderen Farbpigmenten, in infrarotreflektierenden, feuerfeste Überzüge bildenden Massen auf der Grundlage von Magnesiumoxyd und Magnesiumchlorid oder von Silikaten, Zementen und Tonerdegemischen verwendet. Diese Farbpigmente halten höheren Temperaturen stand und zeigen eine sehr starke Reflexion im Infrarot von 0,8 bis über 10 #t. Durch die starke Reflexion dieser Pigmente wird die akkumulierende Wirkung der Infraroteinstrahlung unterdrückt und eine erhebliche Verminderung der Brandgefahr erreicht.According to the invention, mixed crystals of sulfides and / or are therefore Selenides and / or tellurides of the metals of Group II of the Periodic Table, optionally together with other color pigments, in infrared-reflecting, fireproof Coating-forming masses based on magnesium oxide and magnesium chloride or used by silicates, cements and alumina mixtures. These color pigments withstand higher temperatures and show a very strong reflection in the infrared from 0.8 to over 10 #t. Due to the strong reflection of these pigments, the accumulating Effect of infrared radiation suppressed and a significant reduction in the Fire hazard reached.
Es liegt nahe, die reflektierende Wirkung der Pigmente auch derart auszunutzen, daß sie für eine infrarote Fremdstrahlung die Schutzüberzüge der Umgebungsreflexion anpassen. Dadurch wird eine Tarnwirkung für die zu schützenden Gegenstände erreicht. Für die Zwecke des Grenzschutzes, der Einbruchssicherung und ähnlicher Sicherungen hat dieses Verfahren besondere Bedeutung.It stands to reason that the reflective effect of the pigments is also similar to take advantage of the fact that they are the protective coatings of the ambient reflection for an infrared extraneous radiation adjust. This creates a camouflage effect for the objects to be protected. For the purposes of border protection, burglary protection and similar security this procedure is of particular importance.
Es liegt im Erfindungsgedanken, die Pigmente derart auszubilden, daß sie eine beliebige sichtbare Eigenfarbe besitzen und auf anorganischer Basis aufgebaut sind ohne Berücksichtigung ihres infraroten Reflexionsgrades. Ferner können sie auch mit anderen derartigen Farbpigmenten gemischt vorliegen. Es lassen sich somit feuerfeste Schutzüberzüge in allen Farben herstellen und,auch mit variablen Reflexionskoeffizienten versehen.It is part of the concept of the invention to design the pigments in such a way that they have any visible color of their own and are built on an inorganic basis are without consideration of their infrared reflectance. You can also are also mixed with other such color pigments. It can thus Manufacture fire-resistant protective coatings in all colors and also with variable reflection coefficients Mistake.
Es sind zwar weiße Anstrichfarben und infrarotreflektierende Schiffsfarben bekannt, die die Absorption um 3311/o verringern. Demgegenüber kann mit den erfindungsgemäßen Schutzüberzügen eine Reflexion bis über 5011/o erreicht werden, die in Anlehnung an die Umgebung variierbar ist.It is true that they are white paints and marine paints that reflect infrared known to reduce absorption by 3311 / o. In contrast, with the inventive Protective coatings a reflection of over 5011 / o can be achieved, based on is variable to the environment.
Es sind ferner Tarnfarben beschrieben, die jedoch Infrarotstrahlen nur reflektieren, wenn sie in sehr großer Dicke aufgetragen sind, bei ungenügender Dicke jedoch einen Teil der Infrarotstrahlen selbst absorbieren. Danach besitzt die Tarnfarbe keine be- sonderen infrarotreflektierendenEigenschaften. Außer den bekannten weißen Pigmenten und Farbstoffen wie Sulfiden enthält diese Tarnfarbe jedoch nicht die Mischkristalle der erfindungsgemäß verwendeten Substanzen.Camouflage paints are also described which, however, only reflect infrared rays when they are applied in a very large thickness, but absorb part of the infrared rays themselves if they are insufficiently thick. After that, the camouflage has no particular In infrared reflective properties. Apart from the known white pigments and dyes such as sulfides, however, this camouflage paint does not contain the mixed crystals of the substances used according to the invention.
Weiterhin ist die Verwendung der erfindungsgemäßen bzw. ähnlich aufgebauter Mischkristalle für Leuchtfarben bekannt. Im Gegensatz zum Zweck der Tarnfarben handelt es sich bei Leuchtfarben darum, die einfallende energiereiche unsichtbare Strahlung in sichtbare Strahlung umzuwandeln. Für die vorliegende Anwendung ergibt sich, daß hauptsächlich Pigmente mit dem Charakter optischelektrischer und/oder magnetischer Körper geeignet sind. Besonders gute Eigenschaften besitzen die Mischkristalle der Sulfide und/oder Selenide und/oder Telluride des Zinks und/oder Cadmiums und/oder Quecksilbers. Diese Stoffe sollen in mikrokristalliner Form und höchster Reinheit vorliegen öder aber mit Kupfer und/oder Silber und/oder Gold und/oder Nickel und/oder Kobalt und/oder Seltenen Erden und ähnlichen einzeln oder mehrfach aktiviert sein.Furthermore, the use of the inventive or similar structure Mixed crystals known for luminous colors. Acts contrary to the purpose of the camouflage colors In the case of luminous colors, it is the incident high-energy invisible radiation to convert it into visible radiation. For the present application it follows that mainly pigments with the character of opto-electrical and / or magnetic bodies are suitable. The mixed crystals have particularly good properties the sulfides and / or selenides and / or tellurides of zinc and / or cadmium and / or Mercury. These substances should be in microcrystalline form and of the highest purity are present or but with copper and / or silver and / or gold and / or nickel and / or Cobalt and / or rare earths and the like can be activated individually or several times.
Außer den obengenannten Stoffen eignen sich die weiteren Elemente der II. Gruppe des Periodischen Systems als Mischkristalle der Sulfide und/oder Selenide und/oder Telluride, insbesondere wenn sie mit Seltenen Erden doppelt aktiviert sind.In addition to the substances mentioned above, the other elements are suitable Group II of the Periodic Table as mixed crystals of sulfides and / or Selenides and / or tellurides, especially when activated twice with rare earths are.
Darüber hinaus ergeben die Sulfide und/oder Selenide und/oder Telluride des Thalliums und/oder Arsens und/oder Antimons und/oder Wismuts und oder Bleis ähnliche Effekte und sind insbesondere für die Reflexion im ferneren Infrarot oberhalb von 5 #t geeignet.In addition, the sulfides and / or selenides and / or tellurides result of thallium and / or arsenic and / or antimony and / or bismuth and / or lead similar effects and are particularly for the reflection in the far infrared above of 5 #t suitable.
Schutzüberzüge dieser Art können folgende Zusammensetzung haben: Beispiel -" 1 Gewichtsteil Mg0, 1 Gewichtsteil MgC12, 0,3 Gewichtsteile 40 % ZnS -I- 60 % CdS als Mischkristall, 0,1 Gewichtsteil Ultramaringrün.
