Zusammenfassung: | The invention discloses quick-drying notebook paper for ink writing and a manufacturing method thereof, the method comprises the following steps: blending sulfate chemical softwood pulp and sulfate chemical hardwood pulp, and controlling the beating degree of the mixed pulp to be 20-35 degrees SR; the preparation method comprises the following steps: screening, sizing, dehydrating and forming a net part, squeezing, pre-drying, sizing on the surface, post-drying and calendering to prepare the quick-drying paper for ink writing. Glyoxal polyamide resin is added in the sizing process, and the surface sizing is carried out by adopting zirconium-cation polyvinyl alcohol copolymer compounded starch. The glyoxal polyamide resin is added into the pulp, so that the paper sheet fiber network structure is expanded, and the paper ink absorbency is improved; and meanwhile, the influence of a starch coating on drying of the ink is reduced by adopting a method for surface sizing by compounding the zirconium-cation polyvinyl |
