Abstract[German]
Die Erfindung betrifft Kautschukmischungen, enthaltend je mindestens einen Kautschuk, mindestens einen hydroxylgruppenhaltigen oxidischen Füllstoff, mindestens ein Verstärkungsadditiv aus der Reihe der schwefelhaltigen organischen Silane, mindestens einen Vernetzer aus der Reihe Schwefel und Schwefelspender und mindestens eine nichtaromatische, polare Substanz mit 4-12 Kohlenstoffatomen, eine Mischung A enthaltend die mindestens eine Fettsäure und die mindestens eine nichtaromatische, polare Substanz mit 4-12 Kohlenstoffatomen, deren Herstellung und Verwendung, sowie die dadurch erhältlichen Vulkanisate nach dem Vulkanisationsverfahren, insbesondere in Form von Reifen, Teilen von Reifen oder technischen Gummiartikeln.[English]
The invention relates to rubber mixtures containing at least one rubber, at least one hydroxyl-group-containing oxidic filler, at least one strengthening additive from the group of sulfurous organic silanes, at least one cross-linker from the group of sulfur and sulfur donors, and at least one non-aromatic, polar substance with 4-12 carbon atoms, a mixture A containing the at least one fatty acid and the at least one non-aromatic, polar substance with 4-12 carbon atoms, to the production and use thereof, and to the vulcanised materials obtained therefrom by means of the vulcanisation process, in particular in the form of tyres, parts of tyres, or technical rubber products.[French]
