Problems solved by technology

However, screen printing needs to prepare a separate screen for each color, and the use of ceramic ink needs to reserve a drying time, and it will also be accompanied by solvent volatilization, which is easy to cause environmental pollution
[0003] The main component of ceramic pigment ink is ceramic carbon powder. Traditional physical methods are used to produce ceramic toner. Due to the large proportion of ceramic pigments, it is not easy to disperse evenly in resin materials, and the charging of toner is uneven, so that the transfer rate of toner is low. The image density is low and the image effect is not good

[0039] The preparation method of ceramic carbon powder, comprises the steps:

[0040] Material preparation: prepare the mixed dispersion of resin emulsion, pigment dispersion, wax and charge control agent; the mixed dispersion of pigment dispersion, wax and charge control agent all use surfactant as the dispersion;

[0041] Reaction: React the mixed dispersion of resin emulsion, pigment dispersion, wax and charge control agent at a temperature of 40-55°C, then cool, filter, dry and add external additives to obtain ceramic carbon powder.

[0042] Wherein, surfactant can be:

[0043] Anionic surfactants include, but are not limited to: sodium lauryl sulfate, sodium dodecylbenzenesulfonate, sodium dodecylnaphthalenesulfonate, dialkylbenzenealkylsulfate, dialkylbenzenesulfonate Salt and adipic acid, etc.;

[0044] Cationic surfactants include but are not limited to: alkylphenyldimethylammonium chloride, dialkylphenyldimethylammonium chloride, alkylphenyldimethylammonium bromide,...

Abstract

The invention discloses a ceramic toner powder and a preparation method thereof, wherein the ceramic toner powder comprises the following components in parts by weight: resin 15-30 part; pigment 60- 80 part; charge control agent 0.5-5 parts; wax 0.5-5 parts; external additive 0.1-4 parts; the preparation method comprises the following steps: preparing a mixed dispersion of a resin emulsion, a pigment dispersion, a wax and a charge control agent; the pigment dispersion, the mixed dispersion of wax and charge control agent are all dispersed by surfactant; performing reaction: reacting the mixeddispersion of the resin emulsion, pigment dispersion, wax and charge control agent at 40-55 DEG C, performing cooling, filtering, drying and adding external additive to obtain ceramic carbon powder; Ceramic toner powder has good particle shape, narrow particle size distribution and good fluidity, which can meet the requirements of high transfer rate and high image density of ceramic toner powder.

Description

technical field [0001] The invention relates to a ceramic carbon powder and a preparation method thereof, belonging to the technical field of printing materials. Background technique [0002] In the ceramic industry, the patterns on the surface of ceramics are generally realized by hand drawing or screen printing. However, due to the slow speed and low efficiency of manual drawing, and limited by the skills of the painters, the patterns are rough and the delicacy is limited. , Impatient. Today, screen printing can achieve mass production, as we all know, patterns can be printed on water transfer paper by screen printing and ceramic pigment ink, and then transferred on ceramic tiles, glass products, or directly printed with ceramic ink On the wet ceramics and glass products, the pattern is fixed by firing to make personalized porcelain, ceramic tiles, glass and other high value-added products, which are used as decorations for homes and hotels. However, screen printing need...
