Description

Verfahren zur Herstellung von Phonogrammträgern. ,Es ist bekannt, @daß die Zellulose-Ester ais Grundmassen an Stelle von Schellack zur Herstellung von Schallplatten verwendet werden, und daß die Zellulose-Ester zu diesem Zweck genau so vorbereitet werden wie die Nitrozellulose, indem man sie durch Zusätze von Erweichungsmitteln, die Löser oder die N iehtlö ser für Ester organischer Säuren von Zellulose sind, herstellt. Die Mehrheit der hochsiedenden Kampferer satzprodukte, wie Chlorazethyl, Chlorphenole, Kampfer selbst, verschiedenartige Harze und die Reihe der hochsiedenden organischen Ester, kommen hierfür in Frage.Process for the production of phonogram carriers. ,It is known, @ that the cellulose esters ais basic masses instead of shellac for the production of vinyl records are used, and that the cellulose ester is used for this purpose Just like the nitrocellulose, by adding additives to it of emollients, solvents or sewing agents for esters of organic acids made of cellulose. The majority of high-boiling camphor substitute products, such as chloroacethyl, chlorophenols, camphor itself, various resins and the Series of high-boiling organic esters are suitable for this.

Es hat sich nun gezeigt, daß neben den Lösern oder Nichtlösern, die als Erweichungsstoffe dienen, in bekannter Weise die anorganischen Füller in Frage kommen, weil die-Feiben die Tragmasse für die Schallplatten bilden. Es hat sich ferner gezeigt, daß, wenn man den Lösungen oder Pasten aus den in bekannter Weise verarbeiteten Zellulose-Estern Destillationsrückstände aus Erdöl, Teer oder Naturasphalt zusetzt, man dann Massen von ganz besonders günstigen Eigenschaften erhält. Die so erhaltenen Mischungen lassen sich in einer technisch nicht zu erwartenden `eise verpressen und, ergeben Schallplatten mit Linien von äußerster Feinheit und Schärfe. Außerdem haben die Plattcn eine außerordentlich lange Lebensdauer bei hoher Klangreinheit.It has now been shown that in addition to the solvents or non-solvents which serve as emollients, the inorganic fillers come into question in a known manner, because the fibers form the supporting mass for the records. It has also been shown that if one adds distillation residues from petroleum, tar or natural asphalt to the solutions or pastes from the cellulose esters processed in a known manner, then one obtains masses with particularly favorable properties. The mixtures obtained in this way can be pressed in a technically unlikely way and result in records with lines of extreme fineness and sharpness. In addition, the records have an extraordinarily long service life with a high level of sound purity.

Die zur Herstellung von Phonogranimträgern dienende Masse kann heispielsweise wie folgt zusammengesetzt sein: Azethyizellulose 2o kg, Phtalsäure -Ester ro 1:g, Asphaltbitumen 1,40 kg, mineralische Füllstolte o kg.The mass used for the production of Phonogranimträgern can for example be composed as follows: acetyl cellulose 2o kg, phthalic acid ester ro 1: g, Asphalt bitumen 1.40 kg, mineral filler o kg.
