Problems solved by technology

[0003] As far as the current market is concerned, the process of spreading dry granules by dry method is generally adopted, but the production process is relatively complicated, and the production cost is high. When producing dark-colored layouts, many pores are likely to be generated on the brick surface, and the production technology is not stable.
[0004] Chinese patent CN 109516691 A discloses a fully polished ceramic product with a dark pattern and its preparation method. The process involved is also a dry glaze process, but the patent does not disclose the specific process flow, parameters and solid melting process. The particle gradation relationship of the block is just a general description of the effect of the ceramic product prepared by drying the granular glaze

Abstract

The invention provides a kind of dry granular ceramic brick with wet grouting process and its preparation method, comprising: applying surface glaze on the green body, spraying dry granular glaze after printing patterns, and then firing to obtain ceramic bricks, wherein the dry Granular glaze contains: by mass percentage, dry grain A: 15%, dry grain B: 12% to 15%, dry grain C: 13% to 17%, and the softening temperature of dry grain A is 1135°C to 1175°C , the softening temperature of the dry grain B is 980°C to 1050°C, and the softening temperature of the dry grain C is 1020°C to 1127°C. The frit dry granule used in the present invention adopts the collocation of three kinds of dry granules with different melting points. By adopting such a collocation mode, it is convenient to effectively adjust the brick shape and firing temperature during production.

Description

Technical field [0001] The invention relates to a wet-laid and fully polished dry grain brick and a preparation method thereof, and belongs to the field of ceramic brick production. Background technique [0002] With the rapid development of society, people's consumption level has gradually improved. While pursuing a high-quality life, they have paid more and more attention to the decorative effect of the living environment. In the long history of the development of the ceramics industry, traditional polished and polished glazed tiles have been unable to meet people's requirements for decorative effects. Traditional polished glaze and polished tiles have the shortcomings of uneven mirror surface and fuzzy pattern texture. Therefore, it is difficult to achieve clear glaze effect in the production of complicated layout texture details and dark layout design. In order to meet the needs of the market, the development of glazed tiles with high flatness and clear transparency will bec...
