Abstract

The invention discloses a preparation method of colored ink powder. The colored ink powder is prepared from 70-80 parts of polyester resin, 2-4 parts of an organic black pigment, 2-4 parts of an organic yellow pigment, 3-5 parts of an organic carmine pigment, 2-3 parts of an organic cyan pigment, and 1-2 parts of an additive by weight; powdered carbon is used as the organic black pigment, a pigment yellow 12 is used as the organic yellow pigment, the organic carmine pigment is obtained by mixing a pigment red 122 with a pigment blue 60 in the proportion of 1:1, the organic cyan pigment is obtained by mixing a pigment green 36 with a pigment blue 60 in the proportion of 1:1, the additive uses processed silica, and the processed silica comprises one selected from CAB-O-SIL TG-C321, CAB-O-SILTG-C425, and CAB-O-SIL TG-C493. The obtained ink powder has a higher adsorption affinity, and includes a relatively thin printing layer under the condition that the adsorption affinity is ensured.

Description

technical field [0001] The invention relates to the field of toner preparation, in particular to a preparation method of toner color powder. Background technique [0002] The main component of toner (also known as carbon powder) is not carbon, but most of it is composed of resin and carbon black, charge agent, magnetic powder, etc., and toner powder is a kind of toner, by adding Various pigments ensure that the toner can be colored in color. However, the paper printed with toner and color powder on the market fades quickly when it is damp, and the printing layer is thick, resulting in a waste of toner during printing. Contents of the invention [0003] The main purpose of the present invention is to provide a preparation method of toner and color powder, which solves the problems in the prior art that the paper printed with toner and color powder has a fast fading speed when it is damp, and the printing layer is relatively thick, which causes the paper to be printed with t...
