Description

Verwendung von organischen, flexiblen, duroplastischen Kunststoffen zum Gießen von Brillengestellen oder Brillengestelleinzelteilen in Formen Die Erfindung bezieht sich auf das Herstellen von Brillengestellen und deren Einzelteilen aus organischen Kunststoffen. Billige Brillengestelle aus Celluloseacetat als Massenartikel werden durch Gießen in Formen hergestellt. Es lassen sich mit diesem Verfahren Verstärkungseinlagen oder Scharnierteile in das gegossene Brillengestell gleichzeitig und leicht miteinarbeiten, so daß ein zusätzliches Bohren, Fräsen, Einschrauben oder eine sonstige mechanische Hilfsarbeit entfällt. Ferner können der Nasensteg und/oder die Nasenstegplättchen in einem einzigen Arbeitsgang mitangegossen werden.Use of organic, flexible, thermosetting plastics for casting eyeglass frames or eyeglass frame components in molds. The invention refers to the manufacture of spectacle frames and their individual parts organic plastics. Inexpensive cellulose acetate eyeglass frames as mass-produced items are made by pouring into molds. This process can be used to create reinforcement inserts or hinge parts at the same time and easily work into the cast glasses frame, so that an additional drilling, milling, screwing or other mechanical There is no auxiliary work. Furthermore, the nose bridge and / or the nose bridge plates can be cast on in a single operation.

Gegossene Brillengestelle aus thermoplastischen Kunststoffen sind jedoch nicht ausreichend kratz-und biegefest und außerdem zu schwer. Zur Vermeidung dieses Nachteils wird erfindungsgemäß die Verwendung von organischen, flexiblen, durch Einbau oder Zusatz von Substanzen aus langkettigen aliphatischen Molekülgruppen mit etwa 10 C-Atomen aufwärts entweder zum flüssigen Harz oder zum Härter oder als dritte Komponente zur Kunststoffmischung flexibilisierten duroplastischen Kunststoffen, insbesondere Epoxydharzen, ungesättigten Polyesterharzen od. dgl. zum Gießen von Brillengestellen oder Brillengestelleinzelteilen in Formen vorgeschlagen. Cast eyeglass frames made of thermoplastics are however, it is not sufficiently scratch-resistant and resistant to bending, and it is also too heavy. To avoid this disadvantage is the use of organic, flexible, by incorporating or adding substances from long-chain aliphatic molecular groups with about 10 carbon atoms upwards either to the liquid resin or to the hardener or as third component for the plastic mixture flexibilized thermosetting plastics, in particular epoxy resins, unsaturated polyester resins or the like for casting Suggested spectacle frames or individual spectacle frame parts in forms.

Die auf diese Weise modifizierten Duroplaste werden, nachdem sie wasserfrei, luftfrei und von sonstigen Verunreinigungen befreit sind, im Vakuum in Formen zu Brillengestellen vergossen. Der Begriff Gießen schließt das in der Technik übliche Spritzgießen oder Schleudergießen mit ein. In technisch funktioneller Hinsicht haben durchgeführte Versuche ergeben, daß an sich bekannte Formen aus Silikon-, Epoxydharzmassen oder aus ungesättigten Polyesterharzen im Vergleich zu den üblichen Formenmaterialien besonders vorteilhaft sind. In diesem Zusammenhang muß erwähnt werden, daß sich Formen aus den ersterwähnten Werkstoffen durch Herstellen im bekannten sogenannten Abformverfahren unter Benutzung eines Meister- oder Urmodells wesentlich wohlfeiler herstellen lassen als Formen aus den bisher üblichen Werkstoffen. Dies ist insofern wirtschaftlich bedeutsam, als Brillengestelle gewöhnlich in bis zu acht verschiedenen Größenserien angefertigt werden und sie überdies dauernd den Modeschwankungen unterworfen sind. The thermosets modified in this way are after them are water-free, air-free and freed from other impurities, in a vacuum encapsulated in molds to form spectacle frames. The term pouring includes that in the Technique usual injection molding or centrifugal molding with a. In technically functional Regard, tests carried out have shown that known molds made of silicone, Epoxy resin compounds or from unsaturated polyester resins compared to the usual Mold materials are particularly advantageous. In this context it must be mentioned be that forms from the first-mentioned materials by manufacturing in the known So-called molding process using a master or master model is essential Can be produced more cheaply than molds from the materials commonly used up to now. this is economically significant in that eyeglass frames are usually in up to eight different size series are made and, moreover, they are permanent Are subject to fashion fluctuations.

In chemischer Hinsicht tritt bei Verwendung der obengenannten duroplastischen Kunststoffe keine Wanderung des Weichmachers und damit auch keine Benachteiligung des Oberflächenglanzes am Werkstück auf. In chemical terms occurs when using the aforementioned thermosetting Plastics do not have a migration of the plasticizer and therefore no disadvantage the surface gloss on the workpiece.

Die Verbesserung der physikalischen Eigenschaften sind insofern bedeutsam, als das verwendete Kunststoffmaterial durchweg leichter, härter, kratz- und biegefester ist als die herkömmlichen Thermoplaste zum Herstellen von Brillengestellen. The improvement in physical properties is significant in that than the plastic material used, it is consistently lighter, harder, more scratch-resistant and more resistant to bending is than the conventional thermoplastics for manufacturing eyeglass frames.

Ferner ist das thermische Rückbiegungsvermögen größer als bei den üblichen Thermoplasten. Gegenüber den nicht modifizierten Duroplasten weist das erfindungsgemäß verwendete Kunststoffmaterial eine verbesserte Schlagbiegefestigkeit auf. Furthermore, the thermal rebendability is greater than that of the common thermoplastics. Compared to the unmodified thermosets, this shows Plastic material used according to the invention has an improved impact resistance on.

Die flexibilisierten, duroplastischen Kunststoffe dehnen sich beim Erhitzen aus, welche Eigenschaft besonders das Einlegen der Gläser in die Fassungen erleichtert. Sie sind in der Hitze von potenzierter Flexibilität, chemisch und physikalisch resistenter als Cellusoseacetat und dabei von verminderter Feuergefährlichkeit als z. B. Celluloid. The flexible, thermosetting plastics stretch when Heating from which property is particularly the insertion of the glasses in the frames relieved. You are in the heat of potentiated flexibility, chemically and physically more resistant than cellulose acetate and thereby less flammable than z. B. celluloid.
