A kind of preparation method of fully polished flash crystal sand glaze porcelain brick

Abstract

The invention discloses a preparation method of a fully-polished flash crystal sand glaze ceramic tile. The preparation method comprises following steps: S1, zirconite is crushed and subjected to acidpickling, iron removing and screening to remove impurities, high-purity flash particles are extracted, and a material A is obtained; S2, marble polished glaze is calcined, mixed and subjected to ballmilling, basic glaze is prepared, and a material B is obtained; S3, a ceramic tile green body is prepared; S4, after cover glaze is applied to the ceramic tile green body prepared in S3, ink jet printing is performed, and glazing is performed again; S5, drying and firing are performed; S6, the semi-finished ceramic tile product prepared in S5 is polished by a carborundum abrasion block, and mattetreatment is performed by a special flash polishing abrasion block, and finally, the product is checked and put in storage. The preparation method is simple and easy to operate, and the prepared ceramic tile is high in wear resistance, is not prone to breaking or tiny cracking, and has good flash crystal texture, high decorativeness and wider application range.

Description

technical field [0001] The invention relates to the technical field of porcelain tile preparation, in particular to a method for preparing full-polished glitter sand glaze porcelain tiles. Background technique [0002] At present, the common process of making the surface of high-temperature (≥1200°C) porcelain tiles shine under the light includes candy glaze and mica flakes. The above-mentioned materials are sprayed on the surface of the bricks and fired at high temperature. Physical properties and non-reflective or weakly reflective base glaze form a difference in specular reflection of light to achieve a flashing effect and enhance product decoration. [0003] The Chinese patent with the publication number CN103435369 discloses a manufacturing method of wear-resistant and non-slip dry-grained ceramic tiles, including: (1) forming a flat substrate of ceramic tiles for pattern decoration: (2) preparing dry-grained particles with wear-resistant and non-slip properties: ( 3) ...

AI Technical Summary

Problems solved by technology

However, due to the limitations of materials at high temperatures, traditional flash products generally exist in porcelain and third-degree low-temperature products, which are insufficient in wear resistance and have a risk of cracking in the later stage; candy glaze and mica chips are The flash effect achieved by the difference in specular reflection of light can only be applied to matte or semi-polished bricks, and cannot be used in polished products (gloss ≥ 75°) that are in the greatest demand in the market.
