Abstract

Compsn. for polishing optical component parts contains by wt. 45-60 (52) % water, 30-45 (41)% Ce oxide having grain-size 36 mu, and 5-15 (7) % glycerol. Esp. for polishing spectacle lenses of plastics, e.g. diallyl-diglycol carbonate, polymethyl, methacrylate, polycarbonates or epoxide resins. Compsn. is cheaper than a polishing compsn. based on Al2O3 or Sn oxide, and the polished surfaces are of excellent quality. Compsn. is prepd. by mixing the water with the Ce oxide, stirring mixt. through a seive having mesh with 36 mu, and mixing with glycerol.

Description

Mittel zum Polieren von optischen Bauteilen, z.B. Brillengläsern aus Kunststoff Die Erfindung bezieht sich auf ein Mittel zum Polieren von optischen Bauteilen, z.B.Means for polishing optical components, e.g. spectacle lenses Plastic The invention relates to a means for polishing optical Components, e.g.

Brillengläsern aus Kunststoffen.Plastic eyeglass lenses.

Es ist bekannt, optische Bauteile, z.B.It is known to use optical components, e.g.

Brillengläser, mit Mitteln zu polieren, die im wesentlichen aus Aluminiumoxyd oder Zinnoxyd in einer Mischung mit Wasser bestehen.Eyeglass lenses to be polished with means consisting essentially of aluminum oxide or tin oxide mixed with water.

Diese Mittel erfüllen zwar ihren Zweck, sind Jedoch unwirtschaftlich teuer.Although these means serve their purpose, they are uneconomical expensive.

Zum Polieren von optischen Gläsern sind Poliermittel bekannt, die aus Wasser und einer relativ geringen Beimischung von Ceriumoxyd bestehen. Solche DEttel sind zur Bearbeitung von Kunststoffen ungeeignet.For polishing optical glasses, polishing agents are known which of water and one relatively small admixture of cerium oxide exist. Such DEttel are unsuitable for processing plastics.

Aufgabe der Erfindung ist es, ein wirtschaftlich darstellbares Mittel zum Polieren von optischen Bauteilen aus Kunststoffen zu schaffen.The object of the invention is to provide an economically feasible means for polishing optical components made of plastics.

Diese Aufgabe wird erfindungsgemäß durch'ein Poli,ermittel mit folgender Zusammensetzung in Gewichtsprozenten gelöst: 45 - 60 %, vorzugsweise 52 %, Wasser 3o - 45 %, vorzugsweise 41 %, Ceriumoxyd mit einer Körnung < 36 My und 5 - 15 , vorzugsweise 7 %, Glyzerin.According to the invention, this object is achieved by means of a policy with the following Composition dissolved in percent by weight: 45-60%, preferably 52%, water 3o - 45%, preferably 41%, cerium oxide with a grain size <36 My and 5 - 15 , preferably 7%, glycerin.

Das erfindungsgemäße Poliermittel ist wesentlich billiger als Poliermittel auf der Basis von Aluminiumoxyd oder Zinnoxyd, die mit dem Mittel bearbeiteten optischen Flächen sind jedoch von ausgezeichneter Qualität.The polishing agent according to the invention is significantly cheaper than polishing agents on the basis of aluminum oxide or tin oxide, the optical processed with the agent However, surfaces are of excellent quality.

Das Zusammenbringen der Komponenten des erfindungsgemäßen Poliermittels kann vorzugsweise der im Patentanspruch 2 beschriebenen Art entsprechen.The bringing together of the components of the polishing agent according to the invention can preferably correspond to the type described in claim 2.
