摘要:
Rubber composition which can be used in particular for the manufacture of tyres or tyre semi-finished products, such as treads, the said composition being based on at least a diene elastomer, a reinforcing inorganic filler, a coupling agent and a hydroxysilane of formula (I): R1(R2)nSi(OH)3-n in which: n is equal to 0, 1 or 2; R1 represents a hydrocarbon group having at least 4 carbon atoms; R2 represents an alkyl having from 1 to 4 carbon atoms, the R2 alkyls being identical or different if n is equal to 2.
摘要:
A subject-matter of the present invention is a rubber composition intended for the manufacture of tyres or of tyre semi-finished products, based on at least one isoprene elastomer, an inorganic filler as reinforcing filler and a polyfunctional organosiloxane coupling agent capable of providing the bonding between the reinforcing inorganic filler and the isoprene elastomer, comprising per molecule, grafted to its silicon atoms, on the one hand at least one hydroxyl or hydrolysable functional group allowing it to be grafted to the reinforcing inorganic filler and, on the other hand, at least one group bearing at least one azodicarbonyl functional group —CO—N═N—CO— allowing it to be grafted to the isoprene elastomer.

摘要:
Tire belt comprising a rubber composition based on at least one isoprene elastomer, a reinforcing filler, a crosslinking system and an antioxidant agent, characterized in that said antioxidant agent comprises a 4,4′-bis(alkylamino)triphenylamine corresponding to the formula (I): in which R1 and R2, which are identical or different, each represent a linear or branched alkyl group having from 1 to 12 carbon atoms or a cycloalkyl group having from 5 to 8 carbon atoms. Such an antioxidant gives the belt of the invention a better long-term resistance to fatigue and to crack propagation.
摘要:
Tyre and rubber composition for tyre, based on at least one isoprene elastomer (for example natural rubber), an inorganic filler as reinforcing filler (for example silica) and a coupling system which provides the bonding between the said reinforcing inorganic filler and the isoprene elastomer, the said coupling system comprising, in combination: as first coupling agent, a silane sulphide compound; as second coupling agent, an at least bifunctional organosilicon compound (for example an organosilane or an organosiloxane) which can be grafted to the elastomer by means of an azodicarbonyl functional group (—CO—N═N—CO—).
