Abstract

The invention discloses resin for a color regulating agent of a copying machine and a preparation method of a green color regulating agent. The resin for the color regulating agent is a styrene-N-butyl acrylate polymer; the green color regulating agent is prepared from the following raw materials in parts by weight: 100 parts of the styrene-N-butyl acrylate polymer, 5 to 20 parts of a coloring agent and 0.25 to 0.75 part of fumed silica, through the steps of premixing, extrusion smashing, graded smashing and post-mixing, wherein the coloring agent is prepared from at least one of the following components of phthalocyanine blue, phthalocyanine green, aniline blue, carbon black and ferroferric oxide. The resin for the color regulating agent, disclosed by the invention, has the beneficial effects that (1) during testing of a wide-format copying machine, the image quality of a copying product of the color regulating agent containing the styrene-N-butyl acrylate polymer is good; (2) the color regulating agent is stable under different environment conditions of high temperature and high humidity, low temperature and low humidity, normal temperature and normal humidity and the like, the printing durability is stable, and the requirements of the color regulating agent for the wide-format copying machine can be met.

Description

technical field [0001] The invention relates to a toner resin, in particular to a method for preparing the toner resin and cyan toner used in copiers. Background technique [0002] During the copying process, the toner adheres to the paper surface under the action of temperature and pressure with the help of polymer resin. Among them, the toner can be selected from high polymers such as polystyrene, polyacrylic acid, and polymethyl methacrylate; the resin used in the toner generally includes styrene-methacrylic resin, polyamide, polyolefin, styrene-acrylic resin, benzene, etc. Ethylene-butadiene resin, cross-linked styrene polymer, epoxy resin, polyurethane, p-halogenated styrene, etc. [0003] A wide-format copier that can use A0 drawings at most is usually divided into non-contact fixing, contact thermal fixing, pressure fixing and other methods. Due to the large format and fast speed, the toner cannot be fully fused on the printing material, and usually the printing pro...
