Problems solved by technology

However, due to the special package structure of the packaged pigment, there is a dilemma in the process of grinding and refining. On the one hand, in order to ensure its color development effect, it cannot be ground too finely, so as not to damage its packaged structure, but the particles of the pigment If it is too large, the storage stability of the ink will be poor, and precipitation will easily occur; on the other hand, the particles are required to be finer to ensure the smoothness of printing and the stability of the ink, but it is very likely that the package structure will be damaged and it will be difficult to hair color

preparation example Construction

[0032] A preparation method for wrapping ink for ceramic inkjet printing, comprising the steps of:

[0033] 1) Mix the wrapped color material with the solvent, disperse evenly, and obtain the material to be ground;

[0034] 2) Perform primary grinding on the abrasive to be ground, the size of the grinding medium is 1.0-1.5 mm, and grind until the average particle size of the color material is 1.0-1.3 μm to obtain the primary abrasive;

[0035] 3) performing secondary grinding on the primary grinding material, the size of the grinding medium is 0.7-1.0mm and smaller than that of the primary grinding medium, grinding until the average particle size of the color material is 0.7-0.9 μm, and obtaining the secondary grinding material;

[0036] 4) The secondary grinding material is subjected to tertiary grinding, the size of the grinding medium is 0.5-0.7 mm and smaller than that of the secondary grinding, and the average particle size of the color material is 0.5-0.6 μm, and the cer...

Abstract

The invention discloses a preparation method of enveloping ink for small particle size ceramic inkjet printing. By using grinding media with different particle sizes for graded grinding, the encapsulating colorant suitable for ceramic inkjet printing was successfully prepared. The method of the invention is simple and efficient in operation, and is suitable for the preparation of various wrapping inks. In the prepared ceramic ink, the pigment particles are uniform, the particle size distribution is narrow, the average particle size is 500-600nm, and the maximum particle size is no more than 1μm. Porcelain production can also be used in the field of antique bricks. It solves the problem that if the ink is too fine, it will easily precipitate and block the nozzle, and if the ink is too fine, it will cause color difference. The concentrated distribution of ink particle size improves the storage stability of the packaged ink, the printing fluency, avoids the random damage of the color material and improves the stability of the color development. The use of wrapped ink will enrich the pattern design of ceramic tile products, greatly simplify the production process of ceramic tiles, and save the production cost of enterprises.

Description

technical field [0001] The invention relates to a preparation method of ceramic ink, in particular to a preparation method of wrapping ink for ceramic inkjet printing. Background technique [0002] In recent years, ceramic inkjet printing technology, with its extremely high degree of automation and production stability, has rapidly replaced screen and roller printing technology and has become the most popular surface decoration technology. It is known as the third decoration technology revolution in the ceramic industry. With the comprehensive promotion and application of ceramic inkjet printing technology, the demand for ceramic ink as a ceramic surface decoration material is increasing day by day. [0003] Ceramic ink is generally composed of colorants, resins, dispersants, leveling agents, defoamers, anti-settling agents and solvents. The ink for inkjet printing needs to grind and disperse the colorant to prepare ink. The colorant in the ink must be ultra-fine to submicr...
