Problems solved by technology

[0006] Due to the high photon energy of ultraviolet light, the curing speed is fast, but the ozone generated during the printing process will cause damage to the equipment and the human body. In addition, if the ultraviolet light shines directly on the human body, it will damage the skin and cause eye pain
In addition, printers using this toner need to install a mercury UV bulb in the machine to provide UV light for the curing process, but the lamp has the dis

Abstract

The invention provides a blue light curing toner and a preparation method thereof. The blue light curing toner comprises the following components in parts by weight: 60 to 80 parts of unsaturated resin, 0.05 to 2 parts of camphorquinone, 2 to 10 parts of coloring agent, 0.5 to 2 parts of silicon dioxide, 0 to 30 parts of adhesive resin and 0 to 6 parts of wax. Images and symbols which are printed by the toner in a combined manner have excellent abrasion resistance, high-temperature resistance, drug tolerance and mechanical property after being cured. In addition, the invention also provides a preparation method and a curing method of the blue light curing toner.

Description

technical field [0001] The present invention relates to a toner and its preparation method and use method, in particular to a blue light curing toner and its preparation method and curing method. Background technique [0002] A laser printer is a commonly used computer peripheral. It writes an electrostatic latent image on a charged photosensitive drum through laser irradiation, and then attracts charged toner particles to form an image, which is then transferred to a printing medium and fixed by heating and pressure. And image on the printing medium. Due to the advantages of high speed, low noise, waterproof image, and low cost per page, laser printing is widely used. Early toner required a high fixing temperature and needed to preheat the heating roller in advance, which not only required a lot of energy consumption, but also limited the printing speed. [0003] In order to solve the above problems, some toners are made of materials with low softening temperature. Althou...
