Description

DEUTSCHESGERMAN

Es ist bekannt, daJß leicht oxydierbare Stoffe, wie p-Phenylendiamin, Phenyl-/?-naphtylamin, Diphenylp-phenylendiamin, Trimethyldihydrochinolin, mit gutem Erfolg als negative Katalysatoren bei der Kautschukherstellung verwendet werden können, um die Oxydation des Vulkanisierschwefels zu verhindern.It is known that easily oxidizable substances such as p-phenylenediamine, phenyl - /? - naphthylamine, diphenylp-phenylenediamine, Trimethyldihydroquinoline, with good success as negative catalysts in rubber production can be used to prevent the vulcanizing sulfur from oxidizing.

Mit Erfolg wird vulkanisierter Gebrauchskautschuk mit solchen in den Kautschuk diffundierbaren Lösungen in gewissen Abständen behandelt, um eine Konservierung des Kautschuks — Schutz gegen Hart- und Brüchigwerden — (Verhinderung der Biegerisse) zu erzielen. Dies ist mit solchen Lösungen, die die obigen, zum Teil leicht oxydierbaren Stoffe enthalten, nachträglich nicht möglich, da sie sich vorzeitig verändern. Vulcanized rubber with rubber that diffuses into the rubber is successfully used Solutions treated at certain intervals in order to preserve the rubber - protection against hard and brittleness - (prevention of bending cracks). This is with such solutions that the contain the above, in some cases easily oxidizable substances, subsequently not possible because they change prematurely.

Es ist erkannt worden, daß der gewünschte Effekt leicht und sicher erreicht wird,, wenn eine Zubereitung aus Alterungsschutzmitteln verwendet wird, bei der die Alterungsschutzmittel erfindungsgemä.ß in dünnflüssigen Kautschuklösungen im inerten Gasstrom mittels einer Hochdruckpumpe emulgiert werden. Die wirksamen Stoffe werden so weit in geringviskose kolloide Kautschuklösungen gebettet, die nach dem Auftragen einen homogenen Schutzfilm bilden, bis die gelösten Katalysatoren in den Kautschuk eindiffundiert sind.It has been recognized that the desired effect is easily and safely achieved when a preparation is used from anti-aging agents, in which the anti-aging agents according to the invention in low-viscosity Rubber solutions are emulsified in the inert gas stream by means of a high pressure pump. the active substances are so far embedded in low-viscosity colloidal rubber solutions, which after the Apply to form a homogeneous protective film until the dissolved catalysts diffuse into the rubber are.
