Abstract

The invention discloses a preparation method of toner and color powder, which is prepared from the following raw materials in parts by weight: 70-80 parts of polyester resin, 2-4 parts of organic black pigment, 2-4 parts of organic yellow pigment, 3-5 parts of organic magenta pigment, 2-3 parts of organic cyan pigment, 1-2 parts of additive, the organic black pigment adopts carbon powder, the organic yellow pigment adopts Pigment Yellow 12, and the organic magenta pigment adopts pigment Red 122 and Pigment Blue 60 are mixed at a ratio of 1:1. The organic cyan pigment is obtained by mixing Pigment Green 36 and Pigment Blue 60 at a ratio of 1:1. The additive is treated silica, and the treated silica Includes one of: CAB‑O‑SIL TG‑C321, CAB‑O‑SIL TG‑C425, CAB‑O‑SIL TG‑C493. The toner prepared by the invention has stronger adsorption force, and has the advantage of thinner printing layer under the condition of ensuring the adsorption force.

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...
