Abstract

Using silane coupling agent and ammonium zirconium carbonate to modify heavy calcium carbonate separately. Experiments show that using modified calcium carbonate as a filler made of significantly higher than filling in terms of the physical strength of paper. Under 40 ° SR condition, after 1% ammonium zirconium carbonate complex of 4% oxidized starch modified calcium carbonate which works best, to which tensile index up 74.5 N.m / g, while the filling GCC is 54.9 N .m / g. Through the ash of calcium carbonate filler finding that retention of modified is higher than unmodified ,from 31.35 % to 45.94%.
