PROCESS FOR PREPARING A MASTERBATCH IN THE LIQUID PHASE

摘要

The invention relates to a process for preparing a masterbatch in the liquid phase, which is based on one or more diene elastomer latices and on one or more fillers comprising the following successive steps: producing a stable and homogeneous aqueous dispersion (C), by mixing, of one or more diene elastomer latices (A) with one or more stable aqueous dispersions (B) of one or more fillers; homogenization of the aqueous dispersion (C); coagulation within the aqueous dispersion (C) of said diene elastomer latex or latices with the filler or fillers via provision of mechanical energy; recovery of the coagulum; drying of the recovered coagulum in order to obtain the masterbatch.
