The invention relates to a sulfur-crosslinkable rubber mixture comprising at least one diene rubber, regenerate and vulcanization accelerator. For good processability and good vulcanizate properties at high Regeneratanteil contains the rubber mixture at least one diene rubber, more than 5 parts by weight, based on 100 parts by weight of the diene rubber or the diene rubbers, regenerate, - More than 0.5 parts by weight, based on 100 parts by weight of the diene rubber or diene rubbers, benzothiazyl-2-dicyclohexyl-sulfenamide (DCBS) as a vulcanization accelerator and more than 0.25 parts by weight, based on 100 parts by weight of the diene rubber or of the diene rubbers, of at least one further vulcanization accelerator from the group of the sulfenamide accelerators and / or the sulfenimide accelerator group. |
