  • Patent number: 8404084
    Abstract: A filler treatment process enhances the fixation of anionic latex on filler in a short time. Anionic polymer dispersions (latex) are added to papermaking filler slurries at ambient temperature and then mixed with water of temperature higher than the glass transition temperature (Tg) of the latex used. The anionic latexes applied by this process are totally and irreversibly fixed or bound onto the filler particles and the treated filler particle agglomerate to form an aggregated filler slurry which is stable over time. The latex-treated filler slurry can be added to papermaking furnishes at any point prior to the headbox of the paper machine or stored for later use. The latex-treated filler slurry improves filler retention, only slightly reduces sheet strength and improves sizing performance.

  • Publication number: 20110308753
    Abstract: A continuous filler treatment process has been developed to enhance the fixation of anionic latex on filler in a short time. In this process anionic polymer dispersions (latex) are added to common papermaking filler slurries at ambient temperature and then mixed with water of temperature higher than the glass transition temperature (Tg) of the latex used. To efficiently fix the latex the temperature of the filler/latex mixture must be 30-60° C. higher than the Tg of the latex used. The chemical composition of the resin and the type of surfactant used during the emulsion polymerisation process of the polymer latex dispersions are important factors for efficiently fixing the latex onto the filler by adding hot water and improving the properties of paper made with the treated filler. The enhanced fixation of anionic latex onto filler using hot water is done in mixing vessels that can control shear and mixing time.
