specific Embodiment approach

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer and clearer, the present invention will be further described in detail below through specific description and examples.

[0025] In order to solve the problem that the coloring power of ceramic pigments is greatly weakened after ultrafine treatment, a new high-temperature grain inhibitor is provided, which can well control the ceramic pigments during the preparation process of ceramic pigments. The growth of crystal grains enables ceramic pigments to maintain their original chroma well after nanoscale grinding treatment, and at the same time, the particle size distribution can be kept in a relatively narrow particle size range, so as to achieve the goal of ceramic ink preparation industry. The requirements for color materials are standard, and it can effectively save grinding time, save the loss of ceramic pigment grinding media and production costs.

Embodiment 1

[0046] Example 1 (blue material)

[0047] Mix 10kg of magnesium oxide, 40kg of chromium carbide, 40kg of industrial starch and 10kg of nano white carbon black evenly to obtain a high temperature grain inhibitor.

[0048]Mix the raw materials of the blue color material according to the original formula, and mix the high-temperature grain inhibitor with the blue color material evenly, wherein the high-temperature grain inhibitor accounts for 5% of the weight of the blue color material, and then heat Calcined at high temperature for 5 hours, cooled, and pulverized to an average size of 2.5 microns by jet mill to obtain a blue pigment for ceramic ink. The pigments for ceramic inks that were fired after being treated with high-temperature grain inhibitors, and the pigments prepared from the original color formulation without grain inhibitors were used as a control, and the jet mill sorting rate and chromaticity were compared and analyzed , the specific results are shown in Table 1...

Abstract

The invention discloses a high-temperature grain inhibitor for ceramic pigment, the ceramic pigment and a preparation method. The high-temperature grain inhibitor for the ceramic pigment is prepared from the following raw materials: a magnesium compound, carbide, an organic substance and nano white carbon black. The high-temperature grain inhibitor is added in raw materials of the ceramic pigment, so that the ceramic pigment can well control the growth of ceramic pigment grains during preparation, and the grain shape can be kept and low damage degree is achieved when the ceramic pigment is subjected to later superfining processing, therefore, the ceramic pigment has excellent color development character.

Description

technical field [0001] The invention relates to the field of ceramic pigment preparation, in particular to a ceramic pigment high-temperature grain inhibitor, ceramic pigment and a preparation method. Background technique [0002] The current trend of globalization of ceramic inks is more obvious, and the intensity of color development of ceramic pigments prepared by traditional solid-state methods is greatly weakened after nano-processing. After the ceramic pigment is subjected to ultra-fine treatment such as jet milling technology, water milling technology, etc., when it is crushed to a particle size of 800 mesh or more than 1000 mesh, the coloring power will be greatly weakened, or no color will be developed, so that the ceramic ink cannot reach the level of preparation. Industrial requirements for colorants. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The purpose of the present invention is to provide...
