Description

Verfahren zur Herstellung von Polyvinylester enthaltenden plastischen Massen l'ss wurde gefunden, daß Polyvinylester durch Einverleibung von hochmolekularen stickstoffhaltigen Faserstoffen, wie Wolle, Seide u, dgl., in überraschendem Maße versteift werden können. Sie ergeben im Gegensatz zu anderen Faserstoffen, wie beispiels-@@cisc Asbestfasern, in Verbindung mit Überwirgenden Mengen von Polyvinylestern Preßmassen und Lackgrundlagen, die: erst bei höherer Temperatur eiweichen als die .Polyfür sich und von deren Klebrigkeit frt@i sind, ohne eine Einbuße an Elastizität und mechanischer Widerstandsfähigkeit aufzuweisen.Process for the production of plastic materials containing polyvinyl ester Mass l'ss was found that polyvinyl ester by incorporation of high molecular weight nitrogen-containing fibers, such as wool, silk and the like, to a surprising degree can be stiffened. In contrast to other fiber materials, such as - @@ cisc Asbestos fibers, in connection with overwhelming quantities of polyvinyl esters molding compounds and lacquer bases that: only soften at a higher temperature than the .Polyfür themselves and their stickiness are frt @ i without any loss of elasticity and mechanical resistance.

Der Zusatz an Faserstoffen wird bei der Vt--nven.dung in der Lackindustrie und für Shritzgut@masse.n im allgemeinen 'geringer g@elialten werden als bei der Verwendung in der l.i3dustrie der Preßmassen. Immer aber ist es für die günstige Wirkung im Sinne der Erfindung wesentlich, daß die Polyvinylester den Zusatzstoff mengenmäßig übenwiegen. Beispiel 6oo Teile Polyvinylacetat werden in Form einer 25 ojoigen Lösung in Spiritus unter Zusatz von 3o Teilen Phthalsäuremethylester in 3oo Teile kurzfaserigen Wollabfall innig hineingearbeitet. Nach Abdunstung des Lösungsmittels wird die Masse vermahlen und direkt oder nach Vermischung mit anderen geeigneten Zusatzstoffen zur Herstellung von Preßartikeln für die elektrische Industrie, für Grammophonplatten u. dgl. verwendet.The addition of fibers is used in the paint industry and for Shritzgut@masse.n in general 'are less valid than for the Use in the industry of molding compounds. But it is always for the cheap Effect in the context of the invention is essential that the polyvinyl ester is the additive predominate in terms of quantity. Example 600 parts of polyvinyl acetate are in the form of a 25% solution in alcohol with the addition of 3o parts of methyl phthalate intimately worked into 300 parts of short-fiber wool waste. After evaporation of the Solvent, the mass is ground and directly or after mixing with others suitable additives for the production of pressed articles for the electrical industry, used for gramophone records and the like.
