A water-base adhesive mix for producing tyres, having, by weight, 5 to 80% water, 10 to 60% of a cross-linkable unsaturated-chain polymer base, 0.2 to 1% sulphur, 0.1 to 3% zinc oxide, 0.1 to 1% of accelerating agents, 0.1 to 15% of emulsifiers, and 0.01 to 30% of a carbon black having —ArA y type functional surface groups,n where: Ar is an aromatic radical from the group including phenyl, naphthyl, anthracenyl, phenanthrenyl, biphenyl and pyridinyl; A is a COO − or SO 3 − functional group; y is a whole number from 1 to 5 when Ar is phenyl, from 1 to 7 when Ar is naphthyl, from 1 to 9 when Ar is anthracenyl, phenanthrenyl or byphenyl, and from 1 to 4 when Ar is pyridinyl. |
