Abstract

The invention discloses a color fixing agent for a paper surface and a preparation method for the color fixing agent. The color fixing agent is prepared from the following raw materials in parts by weight: 14 to 22 parts of diethylenetriamine, 5 to 13 parts of boric acid, 3 to 7 parts of isoamyl alcohol, 10 to 20 parts of propylene glycol monomethyl ether and 21 to 29 parts of styrene-acrylic emulsion. The preparation method comprises the following steps: mixing, heating and stirring the styrene-acrylic emulsion and the diethylenetriamine, adding the isoamyl alcohol dropwise, and performing cooling stirring treatment; adding a boric acid solution for heating and stirring; adding a propylene glycol monomethyl ether solution dropwise for heating stirring treatment, and reducing the temperature to room temperature to obtain the color fixing agent. The color fixing agent is used for coating the paper surface, the cationic degree of a styrene-acrylic emulsion color fixing agent is increased, the surface property of printing paper can be remarkably improved, the printing quality is improved, and particularly, the water resistance of finished paper is greatly improved. According to the color fixing agent, the color density value of the finished paper mixed with water is greatly increased, the raw materials are simple and extensive, the color fixing agent is free of formaldehyde, environment-friendly, pollution-free, low in production cost, stable in performance and suitable for industrial production, and has good color fixing effects and broad market prospect, and a production process is convenient.

Description

technical field [0001] The invention relates to the technical field of color fixing agents, in particular to a paper surface color fixing agent and a preparation method thereof. Background technique [0002] 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 charged color materials, and play a role in color fixation. High molecular weight cationic polymers, such as polyamine strong cationic polymers such as polyethyleneimine, polyvinylamine, polydimethyldiallylammonium chloride and polyvinylbenzyltrimethylamine chloride, can be used for solidification. color, but these commonly used fixing agents are often not water resistant. Cationic styrene-acrylic emulsion is a copolymer of styrene, acrylate and cationic monomers. During polymerization, functional...
