Influence of Silica and its Different Surface Treatments on the Vulcanization Process of Silica Filled SBR

Abstract

Abstract The effect of different silica treatments on the vulcanization of silica filled Styrene Butadiene Rubber (SBR) is investigated. The concentration, the length and the functionality (coupling or non coupling) of the silane used for this treatment are the parameters studied. It is shown that the silane grafting, by covering the silica surface, modifies the adsorption and desorption on this surface of the accelerators used in the vulcanization system, which in turn modifies the crosslinking kinetic and therefore should influence the final crosslinking state of the matrix.
