Abstract: A method of producing a rubber compound, which includes mixing at least one cross-linkable unsaturated-chain polymer base, silica, a first type of silane coupling agent, and a second type of silane coupling agent. The second type of silane coupling agent is added to the mix after the first type of silane coupling agent has reacted with the silica. The first type of silane coupling agent is a trialkoxymercaptoalkyl-silane, and the second type of silane coupling agent is a mercaptosilane protected in the form of thioester.

Abstract: A water-based cement for producing tires, 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.

Abstract: A water-based cement for producing tyres includes 5 to 80% by weight of water, 10 to 60% by weight of a cross-linkable unsaturated-chain polymer base, 1 to 15% by weight of emulsifiers, and a quantity of metal oxide depending on the desired degree of adhesion.

Abstract: A water-base adhesive mix for producing tires and containing, by weight, 20 to 80% water, 10 to 40% of a cross-linkable unsaturated-chain polymer base, 0.2 to 1% sulphur, 1 to 25% of a reinforcing filler, 1 to 10% of emulsifiers, 2 to 8% of a resin which cross-links by reaction with polyisocyanates, and 0.5 to 5% of an aqueous dispersion having blocked aromatic polyisocyanates with an activation temperature of 120 to 160° C. The blocked aromatic polyisocyanates are produced by reaction of an aromatic polyisocyanate (a), a blocking agent (b), and a nonionic diol alkoxylate (c) of the general formula (I) R1CH2O(CH2CH2O)n(CH2CHCH3O)mR2??(I) where R1 is R2 and R3 are the same or different, and are selected from methyl, ethyl, n-propyl, i-propyl, n-butyl, i-butyl; n is a whole number from 0 to 40 m is a whole number from 0 to 40 n+m is a whole number from 20 to 80.
