20120196976 | USE OF ARYL DINITRILE OXIDES IN ADHESIVE COMPOSITION - The invention relates to the use of an adhesive composition between a vulcanized rubber part and an uncured or prevulcanized or vulcanized rubber part, based on at least one highly unsaturated elastomer chosen from the group formed by natural rubber, polyisoprene, polybutadiene, styrene-butadiene, styrene-isoprene and butadiene-isoprene copolymers and styrene-butadiene-isoprene terpolymers, an aliphatic solvent and a “curing” system comprising at least one stable aryl dinitrile oxide compound. | 08-02-2012 |
20120283360 | Rubber Composition Including an Expoxide Resin - 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. In point of fact, it is desirable to reduce, indeed even in the long run to eliminate, the formaldehyde of rubber compositions due to the environmental impact of this compound. | 11-08-2012 |
20120283372 | Rubber Composition Including a Phenolic Resin - 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. | 11-08-2012 |
