Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with specific embodiments.

[0020] The coloring principle of the embodiment of the present invention is consistent with that of a color laser printer, the difference is that the printing medium toner is replaced with ceramic coloring toner. Since the developing colorants used in laser printers are all organic colorants, the direct use of such colorants cannot adapt to high-temperature sintering of ceramics. Referring to Table 1, inorganic high-temperature colorants and a small amount of organic materials (red: manganese red, yellow: cadmium yellow, cyan: cobalt blue, black: zirconia) are used in the embodiment of the present invention. Inorganic coloring pigments are fused with a small amount of organic polymer materials to form a developing material for laser printers. After electrostatic development of laser printers, various coloring pigments are colored on a plastic film to form colorful...

Abstract

The invention discloses a preparation method of a ceramic coloration toner for a color laser printer, which relates to the ceramic coloration field. The method comprises pre-mixing diethyl terephthalate 25 parts, zirconia 70 parts, cadmium yellow 70 parts, manganese red 70 parts, cobalt ultramarine 70 parts, salicylic acid charge control agent 2 parts and polyethylene wax 2 parts according to weight percentage, and taking silica 1 part for use; extruding by using a double-screw extrusion machine, and performing coarse crushing and fine crushing on the extrudate; grading toner particles to control particle size D50 of the toner at 8.5+/-0.5mum; and adding silica 1 part into the graded toner particles, mixing, and sieving by using a 120 mesh vibrating screen to obtain undersized product which is the ceramic coloration toner for the color laser printer. The method simplifies the process, lowers the cost, is convenient, and saves time and energy.

Description

technical field [0001] The invention relates to the field of ceramic coloring, in particular to a preparation method of ceramic coloring toner for a color laser printer. Background technique [0002] In the ceramic industry, various patterns are made on a ceramic product, which is mainly realized by screen printing. Screen printing is more convenient for large-volume patterns, but for small-quantity and various patterns In other words, it seems that the cost is high and the operation is inconvenient. [0003] Nowadays, some ceramic manufacturers combine with printers to use four coloring and sintering to sinter color images on ceramic products. For the processing of this kind of personalized image, its coloring process is complicated, four colors must be applied, and each color needs to be sintered once, and a color image can be formed after four repetitions. The coloring process of the color pattern on the original ceramic tile can be roughly described as follows: the mon...
