Publication number: 20110308753Abstract: 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.Type: ApplicationFiled: August 30, 2011Publication date: December 22, 2011Inventors: Makhlouf Laleg, Roderick Collins, Danielle Gagne, Steven Middleton
