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 elastomers and on one or more fillers that do not coagulate spontaneously with said latex, 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 that do not coagulate spontaneously with said latex, and which are rendered partially hydrophobic; homogenization of the aqueous dispersion (C), coagulation within the aqueous dispersion (C) of the diene elastomer latex with the fillers that do not coagulate spontaneously with said latex via provision of mechanical energy; recovery of the coagulum, then, drying of the recovered coagulum in order to obtain the masterbatch.
