Description
Verfahren zur Herstellung von nichtsplitterndem Glas und nichtsplitterndes Glas. Gefunden wurde, dass nichtsplitterndes as dadurch herstellbar ist, dass beliebig ;ormtes Glas mit einer Schicht aus polyme- ierten organischen Verbindungen versehen -d.
Als für diesen Zweck besonders geeignete> ymerisierte organische Verbindungen haben h solche erwiesen, die gute Elastizität und hnbarkeit besitzen und in diesen Eigen aften den bisher zur Sicherheitsglasher- llung verwendeten Stoffen überlegen sind, zum Beispiel polymerisierte Acry1säure- er.
Das Verfahren kann derart durchgeführt C'den, däss Polymerisate auf das Glas auf ragen .werden oder auch derart, dass nicht ymerisierte, polymerisierbare Verbindungen das Glas aufgetragen werden, worauf Polymerisation auf dem Glas selbst durch- ührt wird.
Die Polymerisation kann zu verschiedenen tpunkten, also vor, während oder nach der Aufbringung oder auch stufenweise durchge führt werden.
An Stelle der Polymerisate einheitlicher Verbindungen können auch Gemische von Polymerisaten mehrerer ungesättigter orga nischer Verbindungen verwendet werden.
Die ungesättigten, polymerisierbaren bezw. polymerisierten organischen Verbindungen können gegebenenfalls in Lösungen aufge bracht werden und hierauf das Lösungsmittel teilweise oder ganz beseitigt werden.
Klebemittel und Zusatzstoffe wie beispiels weise Trübungsstoffe, Farbstoffe, Weich- machungsmittel, können mit Vorteil zur Ver wendung gelangen, sind aber nicht unbedingt notwendig.
In manchen Fällen ist es zweckmässig, bei erhöhter Temperatur zu arbeiten.
Die Herstellung des nichtsplitternden Glases bei einem andern Druck als einer Atmosphäre ist manchmal vorteilhaft.
Nach dem neuen Verfahren lässt sich nicht splitterndes Glas von grösster Haltbarkeit herstellen, das in ähnlicher Weise wie ge wöhnliches Glas schneidbar ist.
Bemerkenswert ist noch der Vorteil, dass nach dem beschriebenen Verfahren gewölbte bezw. gebogene Gläser hergestellt werden können.
<I>Beispiel 1:</I> Zimtsäuremethylester wird zwischen zwei Glasplatten dem Licht ausgesetzt bis Poly- merisation eingetreten ist. Durch das Poly- inerisationsprodukt tritt feste Verbindung der beiden Platten ein. Die manchmal eintretende Blasenbildung wird durch Pressen in der Wärme beseitigt. <I>Beispiel 2:</I> Eine etwa 0,4 mm starke Platte polyme ren Crotonsäureäthylestei-s wird zwischen zwei Glasplatten gelegt und in einer auf<B>90"</B> an geheizten heizbaren Presse kurze Zeit einem erhöhten Druck ausgesetzt.
Beispiel <I>3:</I> Zwei Bleichgrosse 2 mm starke Glasplatten werden jeweils auf einer Seite mit soviel 20o/oiger Lösung von Acrylsäureinethylester in Aceton übergossen, dass nach Verdunsten des Lösungsmittels ein etwa 0,2 mm starker Film auf der Glasplatte entsteht.
Die beiden Glasplatten werden mit der Filmseite gegeneinander in einer auf etwa 70 bis 80 o angeheizten Presse einem geeigne ten Druck ausgesetzt bis alle Luftblasen entfernt sind.
Process for the production of non-splintering glass and non-splintering glass. It was found that non-splintering as can be produced by providing any shaped glass with a layer of polymerized organic compounds -d.
Polymerized organic compounds which have proven to be particularly suitable for this purpose are those which have good elasticity and resilience and are superior to the substances previously used for the manufacture of safety glass, for example polymerized acrylic acids.
The method can be carried out in such a way that polymers protrude onto the glass or else in such a way that non-polymerized, polymerizable compounds are applied to the glass, whereupon polymerization is carried out on the glass itself.
The polymerization can be carried out at different points, that is, before, during or after application or else in stages.
Instead of the polymers of uniform compounds, mixtures of polymers of several unsaturated organic compounds can also be used.
The unsaturated, polymerizable respectively. polymerized organic compounds can optionally be brought up in solutions and then the solvent can be partially or completely eliminated.
Adhesives and additives such as opacifiers, dyes, plasticizers, can be used with advantage, but are not absolutely necessary.
In some cases it is advisable to work at an elevated temperature.
It is sometimes advantageous to make the non-shattering glass at a pressure other than one atmosphere.
The new process makes it possible to produce extremely durable, non-splintering glass that can be cut in a similar way to ordinary glass.
Also noteworthy is the advantage that, according to the method described, arched respectively. curved glasses can be made.
<I> Example 1 </I> Methyl cinnamate is exposed to light between two glass plates until polymerization has occurred. The polymerization product creates a firm connection between the two plates. The sometimes occurring blistering is eliminated by pressing in the heat. <I> Example 2: </I> An approximately 0.4 mm thick plate of polymeric crotonic acid ethyl ester is placed between two glass plates and subjected to increased pressure for a short time in a press heated to <B> 90 "</B> exposed.
Example <I> 3: </I> Two bleach-sized 2 mm thick glass plates are each doused on one side with enough 20% solution of methyl acrylate in acetone that an approximately 0.2 mm thick film is formed on the glass plate after the solvent has evaporated .
The two glass plates are exposed to a suitable pressure with the film side against each other in a press heated to about 70 to 80 o until all air bubbles are removed.
