Abstract

The present invention refers to a process for preparing solid nanocomposites, formed by elastomeric or thermoplastic latexes and layered compounds, synthetic or natural, intercalated or exfoliated. The novelty shown in the process of this invention is the obtainment of solid nanocomposites through the coagulation of latex and clay dispersions in coagulating agents, by thermal or mechanical means, thereby obtaining solid rubber/clay nanocomposites having a high clay intercalation and/or exfoliation degree. The solid nanocomposite produced by the process of this invention and dispensing with vulcanization has much higher mechanical properties than many conventional polymers or elastomers, as well as excellent properties of resistance to oils and solvents, which makes feasible its application in industrial fields such as in transportation equipment industry, in the manufacture of tires, dynamic and static seals, gaskets, sealants, hoses, belts, among other possible applications. The present invention still refers to articles produced with said solid nanocomposites.
