Problems solved by technology

However, this preparation method has defects such as the inability of the colorant to be uniformly dispersed in the resin, the irregular shape of the prepared color toner, the large particle size and wide distribution, etc., resulting in poor fixability during printing and copying (easy to stick to the roller) , low resolution, poor color, high waste powder rate and other defects, and the process of this method is relatively complicated, so the cost is high

Abstract

The invention discloses a preparation method of color toner, and relates to the technical field of office consumables. The preparation method comprises the following steps: (1) preparing reaction components respectively; (2) adding a macromolecular emulsion, a wax dispersion liquid and a colorant dispersion liquid into deionized water to obtain a mixed solution, and adding humus acid grafted acrylic acid into the mixed solution to obtain a pretreated material; (3) adding a polymerization reaction monomer and an initiator into the pretreated material for a polymerization reaction, controlling the reaction temperature to be between 80 DEG C and 90 DEG C, then carrying out ultrasonic treatment, and then cooling, separating and drying to obtain the color toner. The color toner prepared in the invention is free of roll coating, and the color can be preserved for long time.

Description

technical field [0001] The invention belongs to the technical field of office consumables, and in particular relates to a preparation method of colored carbon powder. Background technique [0002] Color toner is usually composed of polymer resin, colorant (pigment or dye), wax, external additives (charge control agent, etc.) and other components. The traditional color toner used for electrostatic development is usually prepared by melting and pulverizing. This method is to melt and mix resins, colorants, and additives, extrude, cool, crush, ultrafinely pulverize, classify, and add external additives. Finally, Made into colored toner. However, this preparation method has defects such as the inability of the colorant to be uniformly dispersed in the resin, the irregular shape of the prepared color toner, the large particle size and wide distribution, etc., resulting in poor fixability during printing and copying (easy to stick to the roller) , low resolution, poor color, hig...
