Problems solved by technology

The current main technical problem of matte dry granule glaze is the poor transparency and anti-fouling performance of the glaze layer
The lower the gloss of the dry glaze, the easier it is to crystallize, and the large amount of crystal phases produced by crystallization will easily lead to poor opacity and transparency of the glaze surface
In addition, the low gloss of the dry glaze means that the initial melting temperature of the dry glaze is high, and the melting performance is poor, which makes the surface of the dry glaze more porous and easy to hide dirt

preparation example Construction

[0023] The above-mentioned method for preparing high-temperature dry granules includes: mixing the above-mentioned high-temperature dry granule raw materials and 0.5-0.8 parts by weight of additives, adding 40-50 parts of distilled water, and then performing ball milling. The ball-milled material is dried and ground into powder and calcined. The calcining temperature may be 1380-1400°C. After calcination, water quenching, crushing to a suitable particle size, and draining.

[0024] In the technical solution of the present invention, the selected high-temperature dry particles have a particle size of 120 mesh to 250 mesh, so that the glaze surface of the matte dry particles after firing has good pollution resistance and can well meet production problems. If the particle size of the high-temperature dry particles is too large, the large particles are easy to precipitate, and there will be production problems that the spray gun cannot spray the dry particles. At the same time, ...

Abstract

The invention discloses a dull dry granule glaze, a ceramic tile with a dull dry granule glaze surface effect and a preparation method thereof. The matte dry granule glaze, in parts by weight, includes 25-35 parts of high-temperature dry granules, less than 5 parts of matte dry granules, and 40-45 parts of protective glaze; wherein, the high-temperature dry granules account for The mass percentage of glaze is 35-47%; the initial melting temperature of high-temperature dry granules is 1175-1195°C. The matte dry granule glaze of the present invention effectively combines matteness, good transparency, wear resistance, anti-skid and pollution resistance, improves the comprehensive performance of the product, and satisfies the diversified demands of the market for matte dry granule glaze products.

Description

technical field [0001] The invention belongs to the field of ceramic building materials, and in particular relates to a matte dry granule glaze, a ceramic tile with a matte dry granule glaze surface effect and a preparation method thereof. Background technique [0002] At present, the dry granule glazes on the market are mainly matte and glossy, while the matte dry granule glazes are rarely studied. The glossiness of matte dry glaze is lower than 2.5°, and its surface is basically dull, thus producing a low-key and steady visual effect. The current main technical problem of matte dry granule glaze is poor transparency and antifouling performance of the glaze layer. The lower the gloss of the dry glaze, the easier it is to crystallize, and the large amount of crystal phases produced by crystallization will easily lead to poor opacity and transparency of the glaze. In addition, the low gloss of the dry glaze means that the initial melting temperature of the dry glaze is high...
