Embodiment 1

[0060] The preparation process of antique brick is as follows:

[0061] The brick is pressed by a press; dried in a drying kiln; water sprayed on the glaze line; surface glaze is applied; inkjet drawing by an inkjet machine; protective glaze is applied; firing; edge grinding; grading and packaging, and storage.

[0062] Wherein, the surface glaze is composed of the following raw materials according to parts by weight:

[0063] Potassium feldspar: 35 parts, quartz: 10 parts, nepheline: 18 parts, air knife soil: 7 parts, calcined kaolin: 10 parts, alumina powder: 16 parts, burnt talc: 2 parts, zirconium silicate: 15 parts , methyl cellulose: 0.35 parts, sodium tripolyphosphate: 0.5 parts, water: 38 parts.

[0064] According to this surface glaze formula, 3 tons of balls are ball milled until the fineness is 325 mesh sieve, and the sieve is 0.6%. The specific gravity of the ball glaze slurry is controlled between 1.9g / mL~1.95g / mL, and the flow rate is controlled at 40±5 seconds....

[0069] The preparation process of antique brick is as follows:

[0070] The brick is pressed by a press; dried in a drying kiln; water sprayed on the glaze line; surface glaze is applied; inkjet drawing by an inkjet machine; protective glaze is applied; firing; edge grinding; grading and packaging, and storage.

[0071] Wherein, the surface glaze is composed of the following raw materials according to parts by weight:

[0072] Potassium feldspar: 40 parts, quartz: 12 parts, nepheline: 15 parts, air knife soil: 7 parts, calcined kaolin: 15 parts, alumina powder: 12 parts, burnt talc: 1.0 parts, zirconium silicate: 15 parts , methyl cellulose: 0.3 parts, sodium tripolyphosphate: 0.5 parts, water: 38 parts.

[0073] According to the surface glaze formula, 3 tons of balls are ball-milled until the fineness is 325 mesh sieve, and the remaining 0.6% of the sieve is controlled. The specific gravity of the ball glaze slurry is 1.9g / ml~1.95g / ml, the flow rate is 38~42 seconds, and it ...

Abstract

The invention discloses a protective glaze for a matte archaized brick, the archaized brick and a preparation method of the archaized brick, and the protective glaze is prepared from the following raw materials in parts by weight: 30-45 parts of potassium feldspar, 10-20 parts of quartz, 12-20 parts of nepheline, 5-10 parts of Qidao clay, 7-15 parts of calcined kaolin, 15-20 parts of alumina powder, 1-3 parts of calcined talc, 10-20 parts of zirconium silicate, 0.12-0.4 part of methyl cellulose, 0.2-0.6 part of sodium tripolyphosphate and 38-50 parts of water. According to the protective glaze for the matte archaized brick, conventional raw materials in the field are adopted, and by optimizing and improving the formula of the protective glaze, the problem of 'lattice marks at the bottom of the matte archaized brick' is solved.

Description

technical field [0001] The invention relates to the field of ceramic tile preparation, and mainly relates to a protective glaze for matt antique tiles, antique tiles and a preparation method thereof. Background technique [0002] Antique brick is a kind of glazed tile. The body is stoneware (water absorption rate is about 3%) or stoneware (water absorption rate is about 8%). It is used for building walls and floors. Because of the pattern and texture, it is similar to stone veneer. The effect after a long time is generally referred to as antique brick in the industry. "Brick bottom checkered print" means that when ceramic wall and floor tiles are stacked on top of each other during the production process, storage, transportation and construction process, the brick bottom pattern with brick bottom paste powder is printed on the brick surface and is difficult to erase. A production defect that affects the visual aesthetics of the brick surface. "Brick bottom checkered printi...
