Description

Hochdruckdichtungsmaterial, hergestellt aus einer Masse von Kautschuk, Faserstoffen, Vulkanisationsmitteln, Farbstoffen usw. und flüchtigen Lösungsmitteln Es ist bekannt, I3ochdruckdichtungsmaterial aus Kautschuk oder mit Kautschukgehalt, mit oder ohne Faserstoffe, Füllmittel, Farbstoffe o. dgl., herzustellen und durch V ulkanisation zu verfestigen.High pressure sealing material made from a mass of rubber, Fibers, vulcanizing agents, dyes, etc. and volatile solvents It is known to use high-pressure sealing material made of or with a rubber content, With or without fibers, fillers, dyes or the like. To produce and through Solidify vulcanization.

Die bekanntesten und vierbreitesten ,derartigen Materialien sind die sogenannten It-Platten, die in der Hauptsache aus Asbest, Kautschuk, Farbstoff und dem zur Vulkanisation notwendigen Schwefel bestehen.The best known and four broadest such materials are the so-called It panels, which are mainly made of asbestos, rubber, and dye the sulfur necessary for vulcanization.

Bisher werden It-Platten so hergestellt, daß Kautschuk, z. B. in Beüzin gelöst, die Lösung in ein Mischwerk gebracht wird und dann Asbest und die übrigen Stoffe eingetragen werden. Nach gehörigem Durchmischen ist die Masse zur Weiterverarbeitung auf den Walzwerken (Kaiandern) fertig. Die Masse wird auf beheizte Walzen aufgetragen, wobei das Lösungsmittel, z. B: Benzin, verdampft, und die lösungsmittelfneie Masse bildet *die herzustellende Platte.So far, It panels are produced in such a way that rubber, e.g. B. in Beüzin dissolved, the solution is put in a mixer and then asbestos and the rest Substances are entered. After thorough mixing, the mass is ready for further processing finished on the rolling mills (quayside). The mass is applied to heated rollers, wherein the solvent, e.g. B: Gasoline, evaporated, and the solvent-free mass * forms the plate to be produced.

Der in der Mässe enthaltene Schwefel bewirkt bei der angewandten Temperatur Vulkanisation des Kautschuks.The sulfur contained in the measure effects at the applied temperature Vulcanization of rubber.

Die Erfindung beruht nun auf der überraschenden Erkenntnis, daß eine beträchtliche Veredelung der Hochdruckdichtungen erzielt wird, wenn man während der Herstellung ein Ouellungsmittel für Kautschuk -- zum Unterschied von den Lösungsmitteln, wie Benzin - zusetzt.The invention is based on the surprising finding that a considerable refinement of the high pressure seals is achieved when looking during the production of a quenching agent for rubber - in contrast to the solvents, like gasoline - clogs.

Solche Ouellungsmittel sind Alkohole, Äther, Ester, Ketone usw. Der Zusatz derselben erfolgt am besten zu einer sogenannten unechten Lösung von Kautschuk, z. B. in Benzin, mit oder ohne Faserstoffe, Füllmittel, Farbstoffe o. dgl. in Mengen von 5 bis 30 °/o oder mehr, bezogen auf das Gewicht des angewandten Lösungsmittels, worauf in bekannter Weise weiter verarbeitet und vulkanisiert wird.Such source agents are alcohols, ethers, esters, ketones, etc. The It is best to add the same to a so-called fake solution of rubber, z. B. in gasoline, with or without fibers, fillers, dyes o. The like. In quantities from 5 to 30% or more, based on the weight of the solvent used, whereupon it is further processed and vulcanized in a known manner.

Der erwähnte Zusatz kann aber auch bei anderen Herstellungsverfahren, z. B. beim galvanischen Verfahren, erfolgen.The mentioned addition can also be used in other manufacturing processes, z. B. in the galvanic process.

Die nach dem neuen Verfahren veredelten Produkte zeichnen sich durch erhöhte Widerstandsfähigkeit gegen Benzin, Benzol und andere Kautschuklösungsmittel aus, was anscheinend auf einer innigeren Vulkanisation beruht. Bei nach dem neuen Verfahren hergestellten Hochdruckplatten ist, ausweislich amtlicher Prüfungsatteste, auch die mechanische Widerstandsfähigkeit gegen Zerreißen, Bersten und höchste Druck- und "Temperaturbeanspruchungen weitaus höher als bei in üblicher Weise hergestellten Hochdruckplatten. Diese Vorteile sind unter Berücksichtigung des Umstandes, daß die moderne Technik zu immer höheren Drücken und Temperaturen übergeht, nicht hoch genug einzuschätzen.The products refined according to the new process are characterized by increased resistance to gasoline, benzene and other rubber solvents from what appears to be due to a more intimate vulcanization. At after the new one Process produced high-pressure plates is, as evidenced by official test certificates, also the mechanical resistance to tearing, bursting and the highest pressure and "Temperature stresses are far higher than those produced in the usual way High pressure plates. These advantages are considering the fact that modern technology goes over to ever higher pressures and temperatures, not high to judge enough.

Die Einzelheiten der . sich abspielenden Vorgänge sind bei der Schwierigkeit der Materie nicht bekannt oder lassen sich nur vermuten. Es ist möglich, daß das Verfahren gestattet. den- Schwefel feiner und gleichmäßiger zu verteilen, evtl, zu lösen und somit leichter einzumischen, es ist aber auch mÖglich, daß andere. chemische oder kolloidchemische oder aber auch physikalische Erscheinungen ausschlaggebend sind.The details of the. processes taking place are at the difficulty not known of the matter or can only be guessed at. It is possible that that Procedure permitted. den- sulfur finer and more even to distribute, possibly to solve and thus easier to mix, but it is also possible, that other. chemical or colloid chemical or physical phenomena are decisive.

Als Beispiel werden folgende Rezepte angegeben: 1. 25 kg Kautschuk, i 5o kg Benzin, 30 kg Spiritus, 175 kg Asbest, i kg Schwefel.The following recipes are given as an example: 1. 25 kg rubber, 15o kg petrol, 30 kg spirit, 175 kg asbestos, 1 kg sulfur.

11. 27 kg Kautschuk, 16o kg Benzin, 25 kg Essigäther, 175 kg Asbest, io kg Englischrot, io kg Schwerspat, i kg Schwefel.11. 27 kg of rubber, 160 kg of gasoline, 25 kg of vinegar, 175 kg of asbestos, 10 kg of English red, 10 kg of barite, 1 kg of sulfur.

Die Weiterverarbeitung der hergestellten Massen erfolgt wie bisher und wie weiter oben bereits beschrieben.The further processing of the masses produced takes place as before and as already described above.

Zur Herstellung von Kunstleder ist es bekannt, Kautschuklösungen in Benzin, Toltiol, Terpentinöl, Schwefelkohlenstoff o. dgl. gewisse Mengen Alkohol, und zwar etwa 5 °/o, auf das Gewicht des Lösungsmittels bezogen, zuzusetzen. Dabei spielen aber die obigen, für die Hochdruckdichtungen wichtigen Gesichtspunkte keine Rolle.For the production of artificial leather it is known to use rubber solutions in Petrol, tolten oil, turpentine oil, carbon disulfide or similar, certain amounts of alcohol, about 5% based on the weight of the solvent to be added. Included However, the above aspects, which are important for high-pressure seals, do not play a role Role.
