A water-based cement for producing tyres, having water as solvent, cross-linkable unsaturated-chain polymer base, of sulphur, reinforcing filler, zinc oxide, accelerators, and an emulsifier of the general formula (I) [R1R2R3NR5(N(R4)3)n](n+1)+(n+1)X−  (I) where: X is an anionic atom or group R1, R2 and R3, which may be the same or different, are each CmH2m+1, where m ranges between 1 and 3, or CH2CHCH2 or CHCHCH3 R4 is CH2CHCH2 or CHCHCH3 n is 0 or 1 R5 is an aliphatic group C15-C22 when n is 0; and is an aliphatic group C8-C16 when n is 1 when n is 0, at least one of R1, R2, R3 and R5 has a double bond.
