Study of Coating Binder Migration and Affected Parameters

Article Preview

Abstract:

Because of the coating binder migration in cross-section of coating layer, the binder concentration will be different in z-direction of coating layer, which affect some properties of coated paper. The Paper studied the effects of pigment type, coating color solid content and dying temperature on binder migration and affected factors. The z-direction distribution of the coating binder which was tagged with Br in coating layer and its concentration in coating surface were examined quantitatively by using SEM-EDXA and ESCA analysis. The mechanism of binder migration was also proposed. The results indicated that the degree of binder migration is directly proportional to the drying temperature, that the increase of the ratio of calcium carbonate in the pigment content, coating surface binder concentration increased. The result also indicated that the degree of binder migration was increased with reduced the coating solid content.
