Preparation method for polished-crystal crackled glaze tile

Abstract

The invention relates to a preparation method for a polished-crystal crackled glaze tile. The preparation method includes the steps of: press moulding a ceramic green body, applying ground glaze and surface glaze, sintering the tile, printing color glaze, performing primary crack frit dry granule material distribution, performing primary low-temperature sintering, performing secondary transparent frit dry granule material distribution, performing secondary low-temperature sintering, and performing gold plating and polishing. In the invention, a special high-boron frit being high in expansion coefficient is employed, a dry granule stacking method is employed, and the low-expansion-coefficient transparent polished frit dry granule is employed for shielding the cracks, so that the cracks can be blocked for preventing dirt deposition, and meanwhile, through the high-temperature-sputtering multi-arc ionic gold plating process and high-glossiness crystal polishing process, the tile is more than 90 degrees in surface glossiness, so that the cracks has an intensive under-glaze texture and crystal-like sense, and in addition, the method ensures the flatness and internal performance of the tile.

Description

technical field [0001] The invention relates to a method for preparing cracked glazed tiles of polished crystal tiles. Background technique [0002] At present, ceramic crackle glaze is a traditional famous glaze in my country. With its unique style: long and short, sparse and dense, thick and thin, long and short, curved and straight, it resembles cracks and crab claws. Or ice-cracked lines have produced a new artistic style in art porcelain. The simple, natural and rough original ceramic art style presented by cracked glaze has been enduring from ancient times to the present. [0003] Nowadays, small-sized ceramic tiles with crackle glaze (50*50, 100*100, 200*200mm) come into being, but they are not accepted by the public because of their shortcomings of absorbing dirt and absorbing criticism, and the color is monotonous. [0004] Crackle glaze products are due to the fact that the expansion coefficient of the glaze is greater than the expansion coefficient of the blank. D...

Problems solved by technology

[0005] The cracked glaze tiles on the market are directly sprayed with cracked glaze slurry on the green body or plain body or directly piled with high-temperature cracked dry particles and fired at a high temperature of 1200. The cracks penetrate the surface and cannot prevent the penetration of external oil, dust, cement, etc.

After the product is laid, cracks and dirt will soon appear, seriously affecting the appearance of the home, which is a taboo for tile laying
