Abstract
Official abstract text for this publication.
The present invention relates to a process for producing rubber mixtures in a mixing process with, for example, a plurality of mixing stages, where these can optionally be divided into a plurality of sub-steps, comprising the mixing of the following components: one or more rubbers, one or more hydroxylated oxidic fillers, one or more sulphur-containing organosilicon and/or one or more hydroxypolysulphidic compounds, one or more anti-reversion agents selected from 1,6-bis(N,N-dibenzyl-thiocarbamoyldithio)hexane (CAS No.: 151900-44-6), 1,3-bis((3-methyl-2,5-dioxopyrrol-1-yl)methyl)benzene (CAS No.: 119462-56-5) and hexamethylene 1,6-bis(thiosulphate), disodium salt, dihydrate (CAS No.: 5719-73-3), individually and mixtures thereof, where these are incorporated into the mixture in the first mixing stage, one or more vulcanization additives, one or more rubber additives.
