Flash dry granular glaze, flash dry granular polished ceramic plate and preparation method of flash dry granular glaze and flash dry granular polished ceramic plate

Abstract

The invention discloses flash dry granular glaze, a flash dry granular polished ceramic plate and a preparation method of the flash dry granular glaze. The flash dry granular glaze comprises the following components in percentage by mass: 16-35% of high-calcium dry granules and 65-84% of low-temperature transparent dry granules, the difference between the initial melting temperatures of the high-calcium dry granules and the low-temperature transparent dry granules is 40-60 DEG C. Compared with other glittering glaze products, the glittering dry grain polished ceramic plate has the advantages that the glittering phase of the glaze layer is colorless and transparent, the self-through and transparent characteristics of the glaze layer are not influenced while the glaze surface is endowed with glittering decoration, and the impurity feeling and abrupt feeling of the glaze surface can be eliminated. In addition, the flash phase and the glaze layer glass phase have good infiltration, wrapping and chemical bond combination, and glaze layer defects such as bubbles, cavities and glaze layer compactness reduction can be reduced or even eradicated.

Description

technical field [0001] The invention belongs to the field of ceramic building materials, and in particular relates to a flash dry granule glaze, a flash dry granule polished ceramic plate and a preparation method thereof. Background technique [0002] Dry grain polishing is also called mirror polishing. The glazed surface of the ceramic plate using the dry grain polishing process has a high flatness, a strong mirror effect and a good sense of transparency. It is a hot product type in the current architectural ceramics market. After years of research and development, the color and texture of dry grain polished ceramic plates have been very rich. However, how to form a glaze layer with special optical effects, improve the visual impact of products, and improve product differentiation and market competitiveness are currently technical problems to be solved urgently. In the prior art, the process of forming high-temperature (≥1180°C) porcelain tile flashing glaze includes: app...

AI Technical Summary

Problems solved by technology

In the prior art, the process of forming high-temperature (≥1180°C) porcelain tile flashing glaze includes: applying candy glaze on the brick surface and relying on the concave-convex texture of the glaze surface to produce flashing effects, but this method cannot be used for polished tiles; Add flash mica flakes to the glaze, but the lamellar structure of the mica flakes is easily damaged by the melting of the glaze melt, so it can only be used in matte glaze systems; spread high-temperature-resistant metal alloy particles (such as nickel-based alloy), but the above-mentioned particles have poor bonding with the glaze glass phase, which will reduce the physical and chemical properties of the product; dry particles of zircon sand can also be used in the glaze, and the dry particles of zircon sand with a large specific gravity are easy to precipitate in the glaze slurry and There is a risk of radioactivity; or introducing cerium oxide into the glaze and promoting the crystallization of cerium oxide, but the precipitated crystals are opaque or poor in light transmission, which will affect the presentation of inkjet patterns

[0003] To sum up, on the one hand, the flashing decoration of the dry polished ceramic plate through the above means will affect the dry polished glaze layer due to the insufficient light transmittance of the flashing phase. On the other hand, when the glitter phase enters the glaze, the glitter phase is easily eroded by the melt or difficult to form a strong chemical bond with the Si-O network structure in the glaze, so the glitter phase and The wettability and bonding of the glass phase of the glaze face serious obstacles
