METHODE DE PREPARATION D'UN MELANGE MAITRE DE CAOUTCHOUC NATUREL ET DE SILICE |
摘要 |
<p>The invention relates to a method for preparing a silica/natural rubber 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 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.</p> |
