Abstract

PURPOSE:To improve the dispersibility, dripping preventiveness, appropriate viscosity, its ageing stability, kneadability with polymer, self leveling property and tensile strength by surface-treating the heavy calcium carbonate with a rosin ester. CONSTITUTION:Various rosin esters consisting essentially of gum rosin as the residue of gum rosin WW obtained when turpentine oil is distilled from turpentine or abietic acid obtained from the tall oil in pulp mill waste liquor and formed by condensing the rosin including the resin acid and alcohols are excellent as the surface-treating agent capable of remarkably preventing dripping. Any alcohols can be used. Calcium carbonate is agitated by a Henschel mixer, etc., and heated to 100-120 deg.C to completely remove free water, and then the rosin ester is added, sufficiently agitated and mixed to surface-treat the calcium carbonate. The ester is added by 0.05-5.0 pts.wt./pts.wt. CaCO3 in the case of the calcium carbonate having 8-15m<2>/g specific surface.
