Publication number: 20120283372Abstract: A rubber composition which can be used in particular in tires, based on at least one diene elastomer, one reinforcing filler, one crosslinking system, one phenolic resin and one polyaldehyde. The use of a polyaldehyde makes it possible to advantageously replace conventional methylene donors while preventing the production of formaldehyde during the vulcanization of the rubber compositions and thus to limit the environmental impact of these compounds. Furthermore, these polyaldehyde compounds make it possible not only to obtain rubber compositions exhibiting the same low-strain stiffness as conventional rubber compositions using HMT or H3M methylene donors but also, surprisingly, to greatly improve the fatigue strength of the rubber compositions and thus the endurance of the tires.Type: ApplicationFiled: September 13, 2010Publication date: November 8, 2012Inventors: Anne Veyland, José Carlos Araujo Silva, Vincent Hunault

Publication number: 20120283360Abstract: A rubber composition which can be used in particular in tires, based on at least one diene elastomer, one reinforcing filler, one crosslinking system, between 1 and 20 phr of an epoxide resin and between 1 and 15 phr of an amine-comprising curing agent. The pair formed of epoxide resin with an amine-comprising curing agent advantageously replaces the pair formed of phenol/formaldehyde resin, which is a methylene acceptor, with the curing agent(s) HMT or H3M, which are conventional methylene donors. The use of this pair of reactants, epoxide resin and amine-comprising curing agent, makes it possible to obtain rubber compositions exhibiting a greater low-strain stiffness in comparison with conventional rubber compositions, without significantly damaging the hysteresis. Moreover, the combination of a phenolic resin, which is a methylene acceptor, with HMT or H3M, which is a methylene donor, produces formaldehyde during the vulcanization of the rubber composition.Type: ApplicationFiled: October 13, 2010Publication date: November 8, 2012Inventors: Anne Veyland, Vincent Hunault, Jose Carlos Araujo Da Silva

Patent number: 7718717Abstract: A rubber composition usable for the manufacture of tyres, based on at least a diene elastomer, a reinforcing filler and a coupling agent, characterised in that said filler comprises a synthetic metal hydroxide covered with silica, the metal of the hydroxide being selected from the group consisting of Al, Fe, Mg and mixtures of these metals. Use as reinforcing filler, in a diene rubber composition, of such a metal hydroxide. The metal hydroxide is preferably constituted of aggregates (secondary particles) of anisometric form, the primary particles possibly themselves being of anisometric form, for example in the form of rods, which imparts to the compositions of the invention anisotropic properties which are advantageous for separating their mechanical properties. Use of such a rubber composition for the manufacture of rubber articles, in particular of tyres or semi-finished products made of rubber intended for these tyres, in particular of treads.Type: GrantFiled: July 6, 2005Date of Patent: May 18, 2010Assignee: Michelin Recherche Et Technique S.A.Inventors: Arnaud Lapra, Franck Varagniat, Anne Veyland
