摘要

"Elastu00c8mero composition containing reinforcing clay intercalated and exfoliated formed in situ inside the host elastu00c8mero and article, such as a tire, having at least one component of this.This invention relates to a composition of rubber which contains reinforcement of clay organofu00edlica intercalated and at least partially exfoliated formed in situ inside the elastomer host)A hydrophilic clay. The invention particularly relates to a modification in situ of a hydrophilic clay to reconcile the clay with an elastomer based on diene.The clay is converted to be hydrophilic in nature to be more hydrophobic in nature and, therefore,More compatible with the elastomer MIS turando the mass of elastomeric host with a smectite clay, preferably a montmorilonite clay or hectorita,And an ammonium salt of hidrocarbila, such as, for example, a quaternary salt of amu00eanio and, particularly, in the absence of addition of water to the host of the elastomer.Therefore,This procedure in situ intercalation and exfoliation at least partially account with a mixture of mass with a host of the elastomer at an elevated temperature and under conditions of high CIn contrast to the interim isalhamento pre clay in any kind of aqueous base and in contrast with the processing of casting of low viscosity of a simple polymeric thermoplastic.The invention also relates to articles of manufacture, including a tire, having at least one component comprised of such rubber composition.Such tire component may be, for example, a tread of the tire.
