Title
(EN) METHOD FOR PREPARING A MASTERBATCH OF NATURAL RUBBER AND SILICA
(FR) METHODE DE PREPARATION D'UN MELANGE MAITRE DE CAOUTCHOUC NATUREL ET DE SILICE
Abstract
(EN) The invention relates to a method for preparing a masterbatch of natural rubber and silica, comprising the following successive steps of: doping the silica with magnesium, preparing at least one dispersion of the thus-doped silica in water, bringing into contact and mixing a natural field-rubber latex and the aqueous dispersion of doped silica in order to obtain a coagulum, recovering the coagulum, and drying the recovered coagulum in order to obtain the masterbatch.
(FR) L'invention concerne une méthode pour préparer un mélange-maître de caoutchouc naturel et de silice, qui comprend les étapes successives suivantes : - doper la silice avec du magnésium; - préparer au moins une dispersion de la silice ainsi dopée dans de l'eau; - mettre en contact et mélanger un latex de caoutchouc naturel de champ et la dispersion aqueuse de silice dopée pour obtenir un coagulum; - récupérer le coagulum; - sécher le coagulum récupéré pour obtenir le mélange maître.
