초록

In order to elucidate the effects of types and mixing ratio of GCC and clay, coating color concentration, and types of rheology modifiers on high solid coating, various coating colors were prepared, high shear viscosity was measured and then rheology of the coating colors was analyzed. Coating color concentration was able to be increased from 67% to 69% and from 68% to 71% with a higher GCC ratio and with the rheology modifier instead of the synthetic thickener, keeping similar or improved coating color rheology and coated paper quality. The rheological properties of high solid coating color were superior with smaller average particle sizes of clay and latex, wider size distribution of GCC and higher added amount of latex.
