Abstract

The intention discloses microcrystalline glaze and a preparation method thereof. The method comprises the following steps: S1, preparing dry particles; S2,preparing transparent glaze; S3,uniformly mixing the transparent glaze and the dry particles to obtain microcrystalline glaze; the transparent glaze and the dry particles are mixed for use, and a proper formula is adopted, so that the microcrystalline glaze is good in dispersity, good in flowability and high in glossiness; a thick crystal layer can be favorably formed with a cover glaze layer, so that the strength of the glazed tile and thepermeability of a glaze surface are improved; the hardness and the wear resistance of the polished glazed tile are better than those of pure transparent glaze; the water content of green bricks entering a drying kiln is 30% less than that of existing dry particle throwing and spraying green bricks, and the cost for producing a ceramic tile with the specification of 800 * 800mm by applying the microcrystalline glaze is reduced by 30%-50% compared with the cost for producing the ceramic tile with the specification of 800 * 800mm by adopting a dry particle throwing process.

Description

technical field [0001] The invention relates to the technical field of architectural ceramic tiles, in particular to a microcrystalline glaze and a preparation method thereof. Background technique [0002] Glazed tiles have strong physical and chemical properties such as clear colors, rich patterns, no ink discharge on the glaze layer, low water absorption, good water resistance, wear resistance, corrosion resistance, high strength, etc., and have high gloss, fine hair color, and three-dimensional effect Strong and good decorative effect, which makes glazed tiles popular among consumers. [0003] However, at present, wet glaze is commonly used in the production of glazed tiles. The wet glaze mostly adopts the dry grain polishing process of mixing dry particles and suspending agents, or the glaze polishing process of directly pouring transparent glaze; and the pure dry grain polishing process The cost is high, and the physical properties such as hardness and strength of the ...
