METHOD FOR PREPARING A MASTERBATCH OF DIENE ELASTOMER AND SILICA

摘要

The invention relates to a method for preparing a silica/diene elastomer masterbatch, comprising the following successive steps: doping the silica with an at least divalent metallic element; preparing at least one dispersion of the resulting doped silica in water; bringing a diene elastomer latex into contact with the aqueous doped-silica dispersion and mixing them together so as to obtain a coagulum; recovering the coagulum; and drying the recovered coagulum so as to obtain the masterbatch.
