Verfahren zur Herstellung eines Kautschukersatzes.Process for the manufacture of a rubber substitute.
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer Kunstgummimasse für die verschiedensten technischen Zwecke.The present invention relates to a method for producing a synthetic rubber compound for a wide variety of technical purposes.
Bislang war es nicht möglich, einen tatsächlich wertvollen Ersatz für den natürlichen . Kautschuk oder Naturgummi herzustellen, weil alle dazu vorgeschlagenen Rohmaterialien, wie die Kolloide verschiedenster Art, stets in kalter Lösung mit den übrigen Bestandteilen, wie Glyzerin, Kalk usw. zusammengebracht wurden. Dies ergab eine nicht homogene, leicht bröcklige Masse, welche technisch ohne jeden Wert war.So far it has not been possible to find an actually valuable substitute for the natural one . To manufacture rubber or natural rubber, because all the raw materials proposed for it, such as the colloids of various kinds, always in cold solution with the other components, such as Glycerine, lime, etc. were brought together. This gave a non-homogeneous, easily crumbly mass, which was technically without any value.
Nach vorliegendem Verfahren ist es nun gelungen, die Übelstände bei der Erzeugung künstlichen Kautschuks dadurch zu vermeiden, daß man einmal die Einzelbestandteile in bestimmter Reihenfolge nacheinander in Anwendung brachte und sodann die erhaltene Lösung jedesmal erhitzte. Das erhaltene Endprodukt wird dadurch infolge der innigeren Vermischung in der Wärme homogener und gleichzeitig wird seine Festigkeit und Wider-Standsfähigkeit nach jeder Richtung hin bedeutend erhöht.According to the present process it has now been possible to eliminate the deficiencies in the generation To avoid artificial rubber by once the individual components applied in a certain order one after the other and then the one obtained Solution heated every time. The end product obtained is thereby due to the more intimate Mixing in the warmth becomes more homogeneous and at the same time its strength and resistance become significantly increased in every direction.
Das neue Verfahren gestaltet sich nun im einzelnen wie folgt:The new procedure is now structured as follows:
Das als Ausgangsprodukt dienende rohe Knorpelmoos wird sorgfältig verlesen und dadurch von Fremdkörpern gereinigt, um alsdann in lauwarmem Wasser erweicht, um in den Dampfkochtopf gebracht zu werden, in dem es unter beständigem Umrühren zu einer Gallerte eingedickt wird. Von der so erhaltenen Gallerte werden 450 Gewichtsteile, enthaltend 14,31 Gewichtsteile des besten Kolloidstoffs, durch ein feines Haarsieb oder ein Tuch filtriert und abgekühlt. Die erkaltete Gallerte wird. mit 150 Gewichtsteilen Schlemmkreide bzw. Kalk innig vermengt Und abermals in dem Dampfkochtopf erwärmt, wobei eine allzu hohe Temperatur vermieden werden muß, da sonst leicht feine Blasen entstehen.The raw cartilage moss used as the starting product is carefully selected and thereby cleaned of foreign bodies, then softened in lukewarm water to be put in the pressure cooker, in which it is thickened to a jelly with constant stirring. From the so obtained Jelly is 450 parts by weight, containing 14.31 parts by weight of the best colloid substance, filtered through a fine hair sieve or cloth and allowed to cool. The cold jelly will. intimately mixed with 150 parts by weight of chalk or lime And again in heated in the pressure cooker, avoiding an excessively high temperature, otherwise fine bubbles can easily develop.
Nach Zusatz von go Teilen sehr dickflüssigem weißen Sirup und der gleichen Gewichtsmenge Glyzerin wird die Masse noch einmal in dem Dampfkochtopf mäßig erwärmt. Zum Schluß kann dem fertigen Kunstgummi durch Zusatz von Anilinschwarz, Ocker o. dgl. die gewünschte Farbe gegeben werden.After adding a few parts of very thick white syrup and the same amount of glycerine by weight, the mass becomes even more moderately heated in the pressure cooker. Finally, the finished synthetic rubber can through Addition of aniline black, ocher or the like. The desired color can be given.
Da der nach obigem Verfahren hergestellte Kunstgummi nicht geknetet werden kann, so muß er in dickflüssigem Zustande in die betreffenden Formen eingepreßt werden. Das Gußstück wird an der Luft getrocknet und ist nach einigen Tagen gebrauchsfertig. Die Masse kann stets von neuem eingeschmolzen werden, so daß auch alte abgenutzte Stücke niemals ihren Materialwert verlieren.Since the synthetic rubber made by the above method cannot be kneaded, so it must be pressed into the relevant molds in a viscous state. That The casting is air-dried and is ready for use after a few days. the Mass can always be melted down again, so that old worn pieces can also be melted never lose their material value.
