Title (EN) METHOD FOR OBTAINING A COAGULUM AND A MASTERBATCH OF ELASTOMER AND POLYMER FILLER
(FR) PROCÈDE D'OBTENTION D'UN COAGULUM ET D'UN MÉLANGE MAÎTRE D'ÉLASTOMÈRE ET DE CHARGE POLYMÉRIQUE
Abstract:
(EN) The invention concerns a method for obtaining a coagulum made from at least one elastomer and at least one polymer filler, said method comprising the following steps: providing at least one elastomer latex having a zeta potential Z1, providing at least one aqueous dispersion of a polymer filler having a zeta potential Z2, the zeta potential Z2 being of opposite sign to the zeta potential Z1 and the difference between the zeta potentials Z2 and Z1, as an absolute value, being greater than or equal to 20 mV, bringing the elastomer latex into contact with the aqueous dispersion of polymer filler and mixing, in order to obtain a coagulum, and retrieving the coagulum.
(FR) L'invention concerne un procédé d'obtention d'un coagulum à base d'au moins un élastomère et d'au moins une charge polymérique, ledit procédé comprenant les étapes suivantes : disposer d'au moins d'un latex d'élastomère ayant un potentiel Zêta Z1, disposer d'au moins une dispersion aqueuse d'une charge polymérique ayant un potentiel Zêta Z2, le potentiel Zêta Z2 étant de signe opposé au potentiel Zêta Z1 et la différence des potentiels Zêta Z2 et Zêta Z1, en valeur absolue, étant supérieure ou égale à 20 mV, mettre en contact et mélanger le latex d'élastomère et la dispersion aqueuse de charge polymérique pour obtenir un coagulum, récupérer le coagulum.
