Embodiment 1

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

[0061] Press press brick blanks, dry kiln drying, glaze line spray water, apply surface glaze, inkjet inkjet drawing, apply protective glaze, firing; edging; graded packaging, warehousing.

[0062] Among them, the glaze is calculated according to the number of parts by weight and consists of the following raw materials:

[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, zirconia silicate: 15 parts, methylcellulose: 0.35 parts, sodium tripolyphosphate: 0.5 parts, water: 38 parts.

[0064] According to this glaze formula ingredients 3 tons into the ball grinding to a fineness of 325 mesh sieve, the sieve remaining 0.6%, the specific gravity of the glaze pulp is controlled between 1.9g / mL and 1.95g / mL, and the flow rate is controlled at 40±5 seconds; the glaze pulp is stale for 24 hours; before u...

Embodiment 2

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

[0070] Press press brick blanks, dry kiln drying, glaze line spray water, apply surface glaze, inkjet inkjet drawing, apply protective glaze, firing; edging; graded packaging, warehousing.

[0071] Among them, the glaze is calculated according to the number of parts by weight and consists of the following raw materials:

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

[0073]According to this glaze formula ingredients 3 tons into the ball grinding to a fineness of 325 mesh sieve, the remaining sieve 0.6%, the specific gravity of the glaze pulp is controlled to 1.9g / ml ~ 1.95g / ml, the flow rate is 38 ~ 42 seconds, through the 200 mesh sieve; in addition to iron, put into the gla...

Abstract

The invention discloses a protective glaze for matt antique bricks, an antique brick and a preparation method thereof. The protective glaze comprises 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 air knife soil, 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 parts of methyl cellulose ~0.4 parts, 0.2~0.6 parts of sodium tripolyphosphate, 38~50 parts of water. The protective glaze for matt antique bricks uses conventional raw materials in the field, and by optimizing and improving the formula of the protective glaze, the problem of "grid marks on the bottom of bricks" on matte antique bricks is solved.

Description

Technical field [0001] The present invention relates to the field of preparation of ceramic tiles, mainly relates to a protective glaze for matte antique tiles and antique tiles and preparation methods thereof. Background [0002] Antique brick, is a kind of glazed tile, the embryo body is porcelain (water absorption rate of about 3%), or blazing (water absorption rate of about 8%), used for building wall floor, due to the texture of the color, similar to the stone veneer with a long-term effect, the industry is generally referred to as antique brick. "Brick bottom lattice printing" refers to a production defect in which the brick bottom with brick bottom powder is stacked on top of each other during the production process, storage, transportation and construction of ceramic wall and floor tiles, and the brick bottom pattern with brick bottom powder is difficult to erase on the brick surface, which affects the visual aesthetic effect of the brick surface. "Brick bottom lattice st...
