METHODE DE PREPARATION D'UN MELANGE MAITRE DE CAOUTCHOUC NATUREL ET DE SILICE DOPEE MAGNESIUM

摘要

Method for preparing a silica/natural rubber masterbatch, including: doping the silica with magnesium; preparing at least one dispersion of the resulting doped silica in water; bringing a natural rubber field 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.
