Description
Durchsichtiges, lichtreflektierendes Verbundsicherheitsglas Es sind Verbundsicherheitsgläser bekannt, deren Kunstharzzwischenschichten einen Gehalt an optisch wirksamen Substanzen wie Farbstoffen oder Metallsalzen besitzen, die den Zweck haben, die Tönung des Glases zu korrigieren, einen Schutz gegen Blendung bilden oder den Durchtritt von ultravioletten oder infraroten Strahlen verhindern.. Nach einem weiteren Vorschlag werden in die Kunstharzzwischenschicht Eisenfeilspäne oder andere magnetisierbare Teilchen eingebracht und durch magnetische Felder so ausgerichtet, daß sie die Lichtdurchlässigkeit des Glases mehr oder weniger vermindern.Transparent, light-reflecting laminated safety glass There are Laminated safety glasses known whose synthetic resin intermediate layers contain a content of optically active substances such as dyes or metal salts that have have the purpose of correcting the tint of the glass, protecting against glare form or prevent the passage of ultraviolet or infrared rays .. According to a further proposal, iron filings are placed in the synthetic resin intermediate layer or other magnetizable particles introduced and so by magnetic fields aligned that they reduce the light transmission of the glass more or less.
Durchsichtige Gläser mit lichtreflektierenden Eigenschaften, die bei Sicht gegen Licht durchsichtig und bei Sicht gegen Dunkel undurchsichtig sind, werden bisher in Form von durchsichtigen und halbdurchsichtigen Spiegeln., sogenannten Einweg- oder Spionspiegeln, hergestellt. Hierbei wird die Glasscheibe einseitig mit einem reflektierenden Metallbelag, meist Silber, durch chemisches Ausfällen oder Spritzen belegt. Die gegen Oxydation und Korrosion unter Einwirkung der Atmosphärilien empfindliche Metallschicht wird durch einen durchsichtigen Lack geschützt. Da die Lackschicht gegen mechanische Einwirkung oder Einwirkung chemischer Art auf die Dauer keinen Schutz bietet, ist man. dazu übergegangen, eine zweite Glasschicht als Schutz für die Metallschicht anzuwenden. Diese Spiegel wurden dann nach dem aus der Verbundsicherheitsglasherstellung bekannten Verfahren mit Hilfe einer klebenden Kunstharzzwischenschicht hergestellt, In jedem Fall wurde aber bisher zur Erzielung des gewünschten Effektes auf einer der Flächen der Glasscheiben, eine reflektierende Metallschicht aufgebracht. Glasscheiben., die mit einer Metallschicht versehen sind, lassen sich jedoch nicht splittersicher mit der Zwischenschicht verkleben, so daß bei schlag- und stoßartigen Einwirkungen, auf diese Gläser sich Glassplitter von der Metallschicht loslösen. Diese Gläser können. also nicht die an Sicherheitsgläser zu stellenden Anforderungen erfüllen.Clear glasses with light-reflecting properties that can be used at Visibility to light are transparent and when visibility is opaque to dark so far in the form of transparent and semi-transparent mirrors., so-called One-way or spy mirrors, manufactured. Here the glass pane becomes one-sided with a reflective metal coating, usually silver, through chemical precipitation or syringes occupied. The one against oxidation and corrosion under the influence of the atmosphere sensitive metal layer is protected by a transparent varnish. Since the Lacquer layer against mechanical or chemical effects on the Doesn't offer protection for a long time is one. moved on to a second layer of glass to be used as protection for the metal layer. These mirrors were then after Known from the production of laminated safety glass with the help of an adhesive Synthetic resin intermediate layer produced, but in any case has so far been achieved the desired effect on one of the surfaces of the glass panes, a reflective one Metal layer applied. Panes of glass, which are provided with a metal layer, however, cannot be glued to the intermediate layer in a shatterproof manner, so that in the event of sudden and jerky effects, splinters of glass on these glasses loosen the metal layer. These glasses can. so not those on safety glasses meet the requirements to be set.
Dieser Nachteil der bekannten Gläser mit lichtreflektierenden Eigenschaften wird gemäß der Erfindung durch ein Verbundsicherheitsglas vermieden, dessen Kunstharzzwischenschicht lichtreflektierende Substanzen in solcher Menge, Verteilung und Körnung enthält, daß das Verbundglas bei Sicht gegen Licht noch durchsichtig ist.This disadvantage of the known glasses with light-reflecting properties is avoided according to the invention by a laminated safety glass, the synthetic resin intermediate layer contains light-reflecting substances in such quantity, distribution and grain size, that the laminated glass is still transparent when viewed against light.
Als lichtreflektierende Stoffe werden gemäß der Erfindung vorzugsweise Metallpulver verwendet, es können jedoch auch andere reflektierende Stoffe oder auch durchsichtige Stoffe, die einen anderen Brechungsindex als die Kunstharzschicht aufweisen, wie Glaspulver und fein gemahlenes Kunstharz, in diese eingebracht werden.As light-reflecting substances are preferred according to the invention Metal powder is used, but other reflective materials can also be used also transparent fabrics that have a different refractive index than the synthetic resin layer have, such as glass powder and finely ground synthetic resin, are introduced into these.
Das Verbundsicherheitsglas mit lichtreflektierenden Eigenschaften nach der Erfindung, das auch als Wärmeschutzglas Verwendung finden kann., hat gegenüber den mit Metallschichten versehenen Gläsern nicht nur den Vorteil der Splittersicherheit, sondern ist auch unempfindlich gegen Oxydation und Korrosion, so daß seine Kanten nicht wie bei den bekannten Gläsern versiegelt werden müssen.The laminated safety glass with light-reflecting properties according to the invention, which can also be used as heat protection glass., has opposite the glasses with metal layers not only have the advantage of being shatterproof, but is also insensitive to oxidation and corrosion, so that its edges do not have to be sealed as with the known glasses.
