Embodiment 1

[0030] 1 Ceramic green body preparation:

[0031] 1.1 Mineral composition of raw material for billet:

[0032] Porcelain sand (high temperature sand, medium temperature, low temperature sand, potassium sand), clay (black mud, kaolin), talc, etc.

[0033] 1.2 The chemical composition of the billet raw materials:

[0034] SiO 2 67.02%, Al 2 o 3 19.82%, CaO+MgO3.11%, K 2 O+Na 2 O5.37%, Fe 2 o 3 0.64%, TiO 2 0.21%, loss on ignition (IL) 3.83%

[0035] 1.3 Blank powder preparation:

[0036] According to the blank formula, add appropriate amount of water for every 40T kg of grinding, add 0.3-0.5% water glass and sodium tripolyphosphate as water reducer, input the ball mill into the slurry with 0.5-1% fineness and 10,000-hole sieve, and then spray Dry powder, spray dry powder with a moisture content of 6.0-7.0%, stale for 36 hours and wait for moisture balance;

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...
