A kind of placer gold glaze ceramic tile and preparation method thereof

Abstract

The invention relates to a placer gold-glazed ceramic tile and a preparation method thereof, belonging to the technical field of building ceramics. The gold placer glazed ceramic brick comprises a green body layer, a bottom glaze layer, an inkjet pattern layer, a process effect layer and a protective glaze layer from bottom to top; the preparation raw materials of the process effect layer include gold placer crystals and gold placer glaze; the placer gold crystals The preparation raw materials include: albite, kaolin, strontium carbonate, ferric oxide, titanium oxide, barium carbonate, manganese dioxide and burnt talc; the preparation raw materials for the placer gold glaze include: albite, kaolin, potassium feldspar , Fluorite, ferric oxide, quartz, calcite, wollastonite, and burnt talc. The placer gold-glazed ceramic brick is screened through the formula of placer gold crystal and placer gold glaze, and the steps of preparing the two separately and then mixing them, realize the glazed surface under the existing rapid firing process conditions of building ceramic bricks within 1 hour. The placer gold glaze ceramic brick with placer gold crystal realizes the crystallization effect of placer gold glaze.

Description

technical field [0001] The invention relates to a placer gold-glazed ceramic tile and a preparation method thereof, belonging to the technical field of building ceramics. Background technique [0002] With the iterative upgrading of technology and the rapid development of architectural tiles, from small-scale antique bricks to large-scale rock slabs that are popular in the entire industry, there are a variety of products with a variety of colors and crafts, providing consumers with great choices. , greatly improving the home environment. Due to the improvement of consumers' requirements for products, the public not only pays more and more attention to the texture of the surface of ceramic tiles, but also has higher and higher pursuit of art and culture. At present, the pattern design materials of architectural ceramics mostly come from marble, jade, sandstone, and cement, and seldom come from traditional Chinese porcelain. Gold placer glazes are mainly present in traditiona...

AI Technical Summary

Problems solved by technology

The crystals in placer gold glaze art ceramics usually refer to the crystallization of ferric oxide. It is generally believed that ferric oxide dissolves in the glaze at high temperature to form a supersaturated solution of iron, and then precipitates ferric oxide crystals. The glaze is a kind of golden red and shining crystal formed by slow burning, heat preservation, slow cooling and crystallization. The firing method of this kind of placer gold glaze is completely different from the fast firing of traditional architectural ceramic tiles. If you want to produce crystallization effect, Slow firing and slow cooling are required, and the cycle should reach more than 12 hours before the perfect crystalline glaze can be fired. The firing of architectural ceramic tiles generally takes less than 1 hour. It is difficult to realize the crystallization of placer gold glaze under the existing conditions of production of architectural ceramic tiles.
