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)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ [R 1 R 2 R 3 NR 5 (N (R 4 ) 3 ) n ] (n+1)+ (n+1)X - €ƒ€ƒ€ƒ€ƒ€ƒ(I)
where :
X is an anionic atom or group
R 1 , R 2 and R 3 , which may be the same or different, are each C m H 2m+1 , where m ranges between 1 and 3, or CH 2 CHCH 2 or CHCHCH 3
R 4 is CH 2 CHCH 2 or CHCHCH 3
n is 0 or 1
R 5 is an aliphatic group C 15 -C 22 when n is 0; and is an aliphatic group C 8 -C 16 when n is 1
when n is 0, at least one of R 1 , R 2 , R 3 and R 5 has a double bond.
