  • Patent number: 9637601
    Abstract: The invention relates to a process for the preparation of a masterbatch of diene elastomer and reinforcing inorganic filler in accordance with the invention comprises the following successive stages: bringing into contact and mixing one or more aqueous dispersions (B) of one or more hydrophobized reinforcing inorganic fillers, which coagulate(s) spontaneously with the said latex, and one or more diene elastomer latexes (A) in order to obtain a coagulum, without requiring a coagulating agent, recovery of the coagulum, then drying the recovered coagulum in order to obtain the masterbatch.
    Type: Grant

  • Patent number: 9512281
    Abstract: The invention relates to a process for the preparation of a masterbatch in the liquid phase based on one or more diene elastomer latexes and on one or more fillers, comprising the following successive stages: preparation of a stable and homogeneous aqueous dispersion by mixing one or more diene elastomer latexes with one or more stable aqueous dispersions of one or more fillers, the said fillers; homogenization of the aqueous dispersion, coagulation within the aqueous dispersion of the said diene elastomer latex or latexes with the filler or fillers by supplying mechanical energy, recovery of the coagulum, drying the recovered coagulum in order to obtain the masterbatch.

  • Patent number: 9145489
    Abstract: The invention relates to a process for the preparation of a masterbatch in the liquid phase based on one or more diene elastomers and on one or more fillers which do not coagulate spontaneously with the said latex, comprising the following successive stages: preparation of a stable and homogeneous aqueous dispersion (C) by mixing one or more diene elastomer latexes (A) with one or more stable aqueous dispersions (B) of one or more fillers which do not coagulate spontaneously with the said latex and which are partially hydrophobized, homogenization of the aqueous dispersion (C), coagulation within the aqueous dispersion (C) of the diene elastomer latex with the fillers which do not coagulate spontaneously with the said latex by supplying mechanical energy, recovery of the coagulum, then drying the recovered coagulum in order to obtain the masterbatch.

  • Publication number: 20150011678
    Abstract: The invention relates to a process for preparing a masterbatch in the liquid phase based on one or more diene elastomer latexes and on one or more fillers which coagulate spontaneously with said latex, comprising the following successive steps: preparing a stable and homogeneous aqueous dispersion (C) containing one or more surfactants, by mixing one or more diene elastomer latexes (A) with one or more aqueous dispersions (B) of one or more fillers which coagulate spontaneously, homogenizing the aqueous dispersion (C), reducing the chemical potential of the surfactant in the aqueous dispersion (C) until coagulation of said diene elastomer latex(es) with the filler(s), recovering the coagulum, drying the recovered coagulum in order to obtain the masterbatch.
