Problems solved by technology

However, the quality of printers and printer accessories is uneven at present. For example, the toner used in printers has the following common defects: 1) the dispersion is not good, and it is easy to be stuck; 2) the melting temperature of the toner is uneven at high temperature, resulting in printed 3) The properties of the toner are not good, such as not resistant to wiping, poor adhesion, poor gloss, etc.

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0015] This case proposes the printer toner of an embodiment, comprises following material:

[0016]

[0017] Colorants generally refer to pigments. In this case, the specific types of colorants are not limited, so the choice of colorants is free to choose according to actual needs. For example, when black toner is required, carbon black is selected for coloring agent, when a color toner is needed, just select the pigment of the corresponding color.

[0018] The role of potassium silicate is to improve the rub resistance of the toner after transfer. Polyethylene glycol improves the dispersibility of the toner.

[0019] In the above embodiments, the number average molecular weight of polyethylene glycol is 1200-1400 g / mol. The study found that the number average molecular weight o...

Abstract

The invention relates to a toner for a printer. The toner for the printer comprises the following materials in parts by weight: 1-2 parts of a coloring agent, 55-60 parts of water-soluble resin, 2-3 parts of potassium metasilicate and 10-12 parts of polyethylene glycol. Through improvement and optimization of the formula of the toner, the dispersity of the toner is improved; and the toner has excellent glossiness, scrub resistance and color reproduction performance, has relatively high image density and fixing level and low waste powder amount, and is free of falling powder and free of viscosity to a drum or a fixing roller.

Description

technical field [0001] The invention relates to a toner for printers. Background technique [0002] With the popularization of printers, more and more types of printers have entered people's daily life and office. However, the quality of printers and printer accessories is uneven at present. For example, the toner used in printers has the following common defects: 1) the dispersion is not good, and it is easy to be stuck; 2) the melting temperature of the toner is uneven at high temperature, resulting in printed 3) The properties of the toner are not good, such as not resistant to wiping, poor adhesion, poor gloss and so on. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a toner for printers. [0004] Technical scheme of the present invention is summarized as follows: [0005] A printer toner, comprising the following materials: [0006] [0007] Preferably, in the toner for printer,...
