Description

Verfahren zur Herstellung besonders elastischer und biegungsfester Kunsthornmassen aus Casein Die bisherigen Kunsthornprodukte aus Casein haben als Charakteristikum die mit ihrer Härte verbundene Sprödigkeit, wodurch sie sich insbesondere von Celluloid und anderen elastischeren plastischen Massen unterscheiden.Process for the production of particularly elastic and bending resistant Artificial horn compounds made from casein The previous artificial horn products made from casein have been used as Characteristic of the brittleness associated with their hardness, which makes them in particular differ from celluloid and other more elastic plastic masses.

Es wurde nun gefunden, daß! eine Nachbehandlung bereits gehärteter, entweder,ungetrockneter oder getrockneter Caseinprodukte in alkalischen Bädern wesentlich weichere bis lederartige Produkte ergibt. Eine weitere Verbesserung dieser Produkte wurde erreicht, wenn man dieselben mit mehrwertigen Alkoholen, z. B. Glycerin, und auch mit mineralischen und pflanzlichen Ölen durchtränkt. Nach der Trocknung zeigen beide Endprodukte eine sehr große Elastizität und besondere Festigkeit gegen Biegung, ohne daß die sonstigen spezifischen Eigenschaften des Caseinkunsthorns verändert sind.It has now been found that! post-treatment of already hardened, Either undried or dried casein products in alkaline baths are essential results in softer to leathery products. Another improvement on these products was achieved when the same with polyhydric alcohols, e.g. B. glycerin, and also impregnated with mineral and vegetable oils. Show after drying both end products have a very high elasticity and special resistance to bending, without changing the other specific properties of the synthetic casein horn are.

B e i s p i e 1. Man taucht Platten von o, 5 bis i mm Dicke auf die Dauer von 12 Stunden in ein Bad, bestehend aus einer 2oprozentigen Ammoniaklösung; die Platten zeigen nach der Trocknung eine besondere Elastizität, die noch vergrößert werden kann durch eine i2stündige Nachbehandlung mit einem 6oprozentigen Glycerinbad.EXAMPLE 1. Plates from 0.5 to 1 mm thick are dipped onto the Duration of 12 hours in a bath consisting of a 2% ammonia solution; After drying, the panels show a particular elasticity that is even greater can be achieved by a 12-hour post-treatment with a 6% glycerine bath.
