Description
Verfahren zur Herstellung von Formmassen aus vegetabilischen oder künstlichen Grundstoffen unter Verwendung von Füllstoffen, Verstärkungsmitteln o. dgl. Zur Herstellung von Formmassen und Formkörpern aus Natur- oder Kunstharz, Kautschuk, synthetisch hergestellten Werkstoffen auf Kohlebasis usw., werden Füllstoffe, Verstärkungsmittel, Härtemittel usw. verwendet, die je nach der Natur der Grundstoffe und dem Verwendungszweck der Erzeugnisse unterschiedlicher Art sind. Insbesondere bei Kautschuk werden beim Vulkanisieren Ruß oder andere Füll- oder Verstärkungsmittel zugesetzt, die in reicher Auswahl vorgeschlagen wurden. Ruß ist wegen der damit verbundenen Verschmutzung und deren Bekämpfung unbeliebt und verhältnismäßig zu teuer. Andere Zusatzmittel bedingen eine Sonderherstellung in chemischen Betrieben. Die Erfindung bezieht sich auf die Verwendung eines Füllstoffes, der alle gewünschten Eigenschaften vereinigt und ohne weitere Behandlung als Rohstoff in unbegrenzter Menge zur Verfügung steht. Man ging von der Erwägung aus, daß ein vegetabilischer Füllstoff sich auch mit vegetabilischem Grundstoff harmonisch verbinden muß. Diese Verhältnisse liegen auch bei künstlichen Werkstoffen vor.Process for the production of molding compounds from vegetable or artificial raw materials using fillers, reinforcing agents, etc. Like. For the production of molding compounds and moldings made of natural or synthetic resin, rubber, synthetically produced carbon-based materials, etc., fillers, reinforcing agents, Hardeners, etc. are used, depending on the nature of the raw materials and the purpose of use of products are of different types. Especially in the case of rubber, the Vulcanize carbon black or other fillers or reinforcing agents added to the richer Selections were suggested. Soot is because of the pollution associated with it and fighting them is unpopular and relatively too expensive. Other additives require special production in chemical plants. The invention relates to to the use of a filler that combines all the desired properties and is available in unlimited quantities as a raw material without further treatment. It was started from the consideration that a vegetable filler also blends with vegetable Basic material must combine harmoniously. These relationships are also found in artificial ones Materials.
Versuche haben ergeben, daß als Füllstoff, der diese Bedingungen erfüllt, gewöhnliche Rohbraunkohle verwendet werden kann, die sich z. B. ganz vorzüglich als Ersatz für Ruß bei der Herstellung von Gummiwaren eignet. Rohbraunkohle enthält fast alle die Elemente, die zur Bereitung von Füllstoffen, Verstärkungsmittel usw. dienen, und nach den Versuchen zu schließen, passen sich diese Eigenschaften den Bedürfnissen der Baustoffe bei ihrer Verwendung für die Herstellung von Formkörpern an. Trotz der weitgehendsten Verwendung von z. B. Ruß bei der Vulkanisierung ist bis jetzt noch nicht geklärt, worin dessen Wirkungsfaktor liegt, und nur empirische Erfahrung hat dessen Verwendung gefördert.Tests have shown that as a filler that meets these conditions, ordinary raw lignite can be used, which z. B. very excellent Suitable as a substitute for soot in the manufacture of rubber goods. Contains raw lignite almost all of the elements used in the preparation of fillers, Reinforcing agents etc., and after the attempts to conclude, these properties adapt the needs of the building materials in their use for the production of moldings at. Despite the widespread use of e.g. B. is soot during vulcanization It has not yet been clarified what its effect is, and only empirical Experience has encouraged its use.
Bei den Versuchen nach der Erfindung kam minderwertige Rohbraunkohle zur Verwendung, die ungereinigt auf einen Feinheitsgrad von etwa 36oo Maschen pro Quadratzentimeter zu Feinmehl vermahlen wurde. Eine solche Rohbraunkohle enthält außer C und flüchtigen Bestandteilen: Si0z, Al. O., Ca O, Mg O, S O3, FeQ 03. Es ist also festzustellen, daß hier chemische Eigenschaften vorliegen, die in den bekannten, zahlreichen einzelnen Füll- oder Verstärkungsmitteln enthalten sind. Auch lignitische Braunkohle kann verwendet werden.In the experiments according to the invention, inferior raw lignite was used, which, uncleaned, was ground to a fine powder to a degree of fineness of about 3,600 meshes per square centimeter. Such a raw lignite contains besides C and volatile constituents: Si0z, Al. O., Ca O, Mg O, S O3, FeQ 03. It can therefore be stated that chemical properties are present here which are contained in the known, numerous individual fillers or reinforcing agents. Lignitic brown coal can also be used.
Nach der Erfindung wird das Feinmehl aus Rohbraunkohle in den bekannten Mischgeräten, je nach der Art der Grundstoffe (plastisch, pulverig oder flüssig),mit diesenGrundstoffen inniggemischt. Bei der Weiterverarbeitung, wie Vulkanisierung, Härtung, Pressen usw., können sich die einzelnen Eigenschaften der Braunkohle auswirken. So ergibt eine je nach der Braunkohlenart dosierte Zugabe unter Berücksichtigung der Art des Ergebnisses, z. B. bei Kautschuk, eine für alle Zwecke verwendbare Gummimasse, die außerordentlich zäh ist und z. B. dem mit Ruß hergestellte» Gummi nicht nachsteht, ja diesen zum Teil übertrifft. Die zur Wirkung erforderliche Füllstoffmenge hängt von der Kohlenart ab, so daß für jede Rohbraunkohle eine entsprechende Dosierung gewählt werden muß. Das Vorhandensein von Schwefel fördert die Vulkanisierung.According to the invention, the fine flour from raw lignite is used in the known Mixing devices, depending on the type of raw materials (plastic, powder or liquid), with these basic materials are intimately mixed. In further processing, such as vulcanization, Hardening, pressing, etc., can affect the individual properties of lignite. This results in a metered addition depending on the type of lignite, taking into account the type of result, e.g. B. in the case of rubber, a rubber compound that can be used for all purposes, which is extremely tough and z. B. is not inferior to the »rubber made with soot, yes it exceeds this in part. The amount of filler required to work depends on the type of coal, so that an appropriate dosage for each raw lignite must be chosen. The presence of sulfur promotes vulcanization.
