Description
Verfahren zur Herstellung von Kautschukmischungen Die Erfindung betrifft das Einmischen bestimmter Beschleuniger, Alterungsschutzmittel oder Weichmacher in Kautschuk oder dessen Mischungen zur Herstellung von Vormischungen.Process for the preparation of rubber compounds The invention relates to Mixing in certain accelerators, anti-aging agents or plasticizers in rubber or its mixtures for the production of premixes.
Die bisher in derKautschukindustrieüblichen zahlreichen, Beschleuniger, Alterungsschutzmittel oder Weichmacher sind teilweise leicht schmelzbare Festkörper, klebrige Halbfestkörper oder Flüssigkeiten, die nur schwer in zufriedenstellender Weise auf gewöhnlichem Wege, etwa durch Mischmühlen, dem Kautschuk einverleibt werden können.The numerous accelerators, Anti-aging agents or plasticizers are in some cases easily meltable solids, sticky semi-solids or liquids that are difficult to achieve satisfactorily In the usual way, for example by mixing mills, they can be incorporated into the rubber can.
Aus diesem Grunde hat man bereits vorgeschlagen, diese Füllstoffe in Pulverform der flüssigen, mit einem Alkali versetzten Kautschukmilch zuzusetzen, wie man auch versucht hat, zur Verhütung von Schimmelbildung dem Rohkautschuk eine Asphaltlösung beizumischen. Die erstgenannte Maßnahme läßt die Frage der .besseren Verarbeitung von plastischem Kautschuk offen, während die Zufügung von Asphaltlösung für die Herstellung von Vormischungen nicht brauchbar ist.For this reason it has already been proposed to use these fillers to be added in powder form to the liquid rubber milk to which an alkali has been added, as has also been tried to prevent the formation of mold, the raw rubber a Mix in asphalt solution. The first measure leaves the question of the better Processing of plastic rubber open while adding asphalt solution is not useful for the production of premixes.
Gemäß der Erfindung sollen Mischungen von Beschleunigern, Weichmachern oder Alterungsverhütern, soweit sie in leicht schmelzbarer Fest-, klebender Halbfest- oder leicht beweglicher flüssiger Form vorliegen, mit Kautschuk oder dessen Mischungen zur Bildung von Vormischungen hergestellt werden, indem die zuvorgenannten,leicM schmelzbaren Fest-, klebenden Halbfest- oder leicht beweglichen flüssigen Körper durch Anwendung von Hitze in leicht flüssigen Zustand übergefülv-t und in dieser Form einer wäßrigen Kautschukdispersion beigemengt werden, so @laß diese koaguliert.According to the invention, mixtures of accelerators, plasticizers or anti-aging, insofar as they are in easily meltable solid, adhesive semi-solid or in a readily mobile liquid form, with rubber or its mixtures to form premixes are prepared by the aforementioned, leicM fusible solid, adhesive semi-solid or easily movable liquid body by the application of heat in a slightly liquid state and in this Are added in the form of an aqueous rubber dispersion, so @ let this coagulate.
Als Zusatzstoffe für den Kautschuk können beispielsweise die verschiedenen flüssigen, viscosen oder halbfesten Beschleuniger bzw. Alterungsverhüter der Aldehydaminverbindungen, wie Acetaldehyd und Anilin oder Aldol und a-Naphthylamin, verwandt werden. Ferner können Ölsäure, Stearinsäure und andere flüssige, halbfeste oder sonstige schmelzbare organische Säuren, wie auch Kienöl, Baum--,vollsaatbl, Anilin, nordisches Holzteeröl, Steinkohlenteeröl, Vaseline, hierzu einzeln oder in Mischung miteinander benutzt werden; auch läßt sich Zinklaurat oder ein Gemisch von niedergeschmolzenem Paraffinwachs mit Stearinsäure auf diese Weise beifügen.As additives for the rubber, for example, the various liquid, viscous or semi-solid accelerators or anti-aging agents for aldehyde amine compounds, such as acetaldehyde and aniline or aldol and a-naphthylamine. Further can oleic acid, stearic acid and other liquid, semi-solid or other fusible organic acids, such as pine oil, tree oil, full seed oil, aniline, Nordic wood tar oil, Coal tar oil, petroleum jelly, used individually or in a mixture with one another will; Zinc laurate or a mixture of melted paraffin wax can also be used with stearic acid in this way.
In gleicher Weise lassen sich hierzu Lösungen oder Suspensionen von Mischstoffen in diesen Mitteln oder in Mischung mit diesen entweder allein oder in Kombination verwenden, wie :etwa eine solche von Harz mit Kienöl oder des als Beschleuniger dienenden Diphenylguanidins bzw. des als Oxydationsverhüter angewandten Phenylnaphthylamins mit Ölsäure oder geschmolzener Stearinsäure; ferner eine Mischung von Mercaptobenzothiazol mit geschmolzener Stearinsäure oder dessen Lösung in Anilin mit oder ohne Zusatz weiterer Stoffe, wie Benzol.Solutions or suspensions of Mixed substances in these agents or in a mixture with them either alone or use in combination, such as: such as those of resin with pine oil or des as Serving accelerators Diphenylguanidines or as an anti-oxidant applied phenylnaphthylamine with oleic acid or molten stearic acid; further a mixture of mercaptobenzothiazole with molten stearic acid or its Solution in aniline with or without the addition of other substances such as benzene.
Um eine vorzeitige Erstarrung zu verhüten, wird vor dem Beimengen des Zusatzstoffes, etwa geschmolzener Stearinsäure, die Kautschukmilch zweckmäßig auf etwa 7o° vorerwärmt.In order to prevent premature solidification, before adding of the additive, such as molten stearic acid, the rubber milk is expedient preheated to about 70 °.
Unter den vorerwähnten wäßrigen Kautschukdispersionen sind auch solche, die aus Guttapercha, Balata o. dgl. Pflanzenharzen bestehen bzw. diese enthalten, zu verstehen, wobei diese Stoffe auf natürliche oder künstliche Weise gewonnen, auch konzentriert, vulkanisiert oder in rohem Zustand sein können. Es sind ferner die künstlichen wäßrigen Dispersionen von koaguliertem, synthetischem oder vulkanisiertem Kautschuk, Abfall oder regeneriertem Kautschuk in diesem Begriff eingeschlossen.Among the aforementioned aqueous rubber dispersions are also those which consist of or contain gutta-percha, balata or similar vegetable resins, to understand, these substances being obtained naturally or artificially, can also be concentrated, vulcanized, or in the raw state. There are also the artificial aqueous dispersions of coagulated, synthetic or vulcanized Rubber, waste or reclaimed rubber are included in this term.
Die einzelnen wäßrigen Lösungen können ferner allein oder in Mischung miteinander behandelt werden. Gegebenenfalls können den Dispersionen, um ein vorzeitiges Gerinnen zu verhüten, kleine Mengen eines Alkalis, wie Ammoniak oder Ätzkali, zugesetzt werden.The individual aqueous solutions can also be used alone or as a mixture be treated with each other. If necessary, the dispersions can be used to prevent premature To prevent curdling, add small amounts of an alkali such as ammonia or caustic potash will.
Dient als Zusatzstoff eine niedergeschmolzene Säure, etwa Stearinsäure, so kann dieser in geringer Menge gegebenenfalls die wasserunlösliche Verbindung eines Metalls mit einer Fettsäure, wie Magnesiumstearat oder Zinkstearat, zugesetzt werden.A melted acid, such as stearic acid, is used as an additive, so this can optionally contain the water-insoluble compound in a small amount of a metal with a fatty acid such as magnesium stearate or zinc stearate is added will.
Das sich ergebende weiche Endprodukt bildet dann eine gleichmäßige Mischung von Kautschuk und der Stearinsäure. Die Endprodukte bilden für gewöhnlich eine weiße Masse, wobei die Farbe hauptsächlich der Wirkung des Wassers in der Kautschukdispersion zuzuschreiben ist.The resulting soft end product then forms a uniform one Mixture of rubber and stearic acid. The end products usually form a white mass, the color being mainly the effect of the water in the rubber dispersion is attributable.
Vor der Weiterverarbeitung des Produktes zu einer Vormischung wird das Wasser durch Trocknen oder Vorwalzen zu Platten entfernt. Diese Maßnahme kann jedoch auch entfallen und das Produkt, so wie es ist, weiterverarbeitet werden.Before further processing the product becomes a premix the water is removed by drying or pre-rolling into panels. This measure can however, they are also omitted and the product can be further processed as it is.
Zweckmäßig werden jeweils nur kleine Mengen von Kautschuk und Zusatzmittel verarbeitet, die in einem bestimmten Verhältnis zueinander stehen. So wird man etwa kleine Kuchen herstellen, die aus einem Gemisch von 450 g Stearinsäure mit Zoo, 75 oder 5o % Kautschuk bestehen.Only small amounts of rubber and additives are advisable in each case processed, which are in a certain relationship to each other. That's how you become make small cakes from a mixture of 450 g stearic acid with zoo, 75 or 50% rubber.
iDie erfindungsgemäß hergestellten Mischungen lassen sich vorteilhaft zur Weiterverarbeitung in Mischmühlen unter Beifügung von Kautschuk rnit oder oluie Zusatz weiterer Misch- oder Füllstoffe oder Vulkanisatoren verwenden.The mixtures prepared according to the invention can advantageously be used for further processing in mixing mills with the addition of rubber with or oil Use additional mixers or fillers or vulcanizers.
