Abstract

The invention discloses a surface-sizing fixing agent for color-jet paper and a preparation method and the application thereof, and belongs to the field of preparation technologies of papermaking chemicals. The method comprises the following steps: gelatinizing cationic starch, ammonium persulfate and water under water bath stirring; adding ferrous chloride water solution and hydrophilic monomer solution; dripping hydrogen peroxide diluent for initiation; adding hydrophobic monomer and rosin into a reaction system for monomer pre-emulsification; increasing the temperature to 90-92 DEG C, and dripping hydrogen peroxide diluent for initiation and then reaction for 2-3h; and increasing the temperature to 95-99 DEG C for reaction for 1h, and then naturally cooling to 20-50 DEG C to manufacture the surface-sizing fixing agent for color-jet paper. The prepared surface-sizing fixing agent for color-jet paper is formulated into water solution and then mixed with the cationic starch or polyvinyl alcohol, and meanwhile, an album paper coating cross-linking agent is added for being mixed and applied to improve the surface quality of printing paper, improve the printing quality and particularly greatly improve the water resistance of finished paper.

Description

technical field [0001] The invention belongs to the field of papermaking chemicals preparation technology, and in particular relates to a color-jet paper surface sizing color-fixing agent, a preparation method thereof and an application in improving the printing quality of the color-jet paper. Background technique [0002] Sizing and coating are commonly used methods for preparing color-jet paper. Compared with coating, sizing has less consumption, lower material cost and production cost, but the printing quality of finished paper is not as good as that of coated paper. It is necessary to improve the quality of sizing color-jet paper. To approach and achieve the print quality of coated paper. [0003] Color-fixing agent is an auxiliary agent commonly used in color-jet paper coatings to fix colorants, and its common characteristics are cationic and high molecular weight. High ionic strength, strong interaction with color dye molecules, can quickly capture and fix negatively ...
