Abstract
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.
Claims19
A method for preparing a masterbatch of silica/natural rubber comprising:
- doping a silica with magnesium thereby obtaining a doped silica;
- 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, thereby obtaining a coagulum;
- recovering the coagulum;
- and
- drying the recovered coagulum, thereby obtaining the masterbatch.
