Abstract

The invention relates to a color printing toner and a preparation method thereof, and belongs to the technical field of toner preparation. The color printing tone is prepared from the following raw materials in parts by weight: 60-70 parts of pigment powder, 10-15 parts of modified starch, 10-20 parts of styrene-acrylic resin, 10-15 parts of talcum powder and 1-5 parts of sodium silicate. The preparation method comprises the following steps: mixing pigment powder, modified starch, talcum powder and sodium silicate evenly; carrying out ball-milling for 30-35 minutes; adding 100-110 parts of deionized water; adding styrene-acrylic resin, heating to 50-56 DEG C, and keeping for 50-55 minutes; cleaning with 8-10fold deionized water, filtering and drying into a granular material; and screening the material, selecting 2-10micron granules, and drying at 50-55 DEG C for 30-40 minutes, so as to obtain the product. The toner granules are regular and uniform in shape, clear to develop and image, distinct in color layer, suitable for different models, and relatively low in preparation cost; and industrialized production is easy to achieve.

Description

technical field [0001] The invention relates to a printing toner, in particular to a color printing toner and a preparation method thereof, belonging to the technical field of toner preparation. Background technique [0002] Printing (Printing, Graphic Arts, also using Graphic Communications, that is, graphic communication) is to transfer the ink to the surface of paper, fabric, leather and other materials through the processes of plate making, ink application, and pressure on originals such as text, pictures, and photos , a technique for batch-copying the contents of manuscripts. [0003] The global printing market is divided into three major blocks: the United States, Europe and Asia each account for one-third of the global printing market. The total output value of China's printing industry has jumped to the third place in the world in 2006. In 2012, the General Administration of Press and Publication released the first white paper "Development of China's Printing Indus...
