Embodiment 1

[0009] Example 1: Taking a ceramic tile with a specification of 300×300mm as an example, the distribution of pits on the surface of the green body: 39 pits with a diameter of 5mm, 23 pits with a diameter of 3mm, and 12 pits with a diameter of 2mm or less. After the green body is formed by machine pressing, the water content of the green body is reduced from about 6.3-7% to 0.8-1.5% after passing through a drying kiln at 180°C-210°C for 20 minutes. After the biscuit with pits is dried, a uniform metallic glaze is spread on the biscuit by using a glaze spraying equipment. The water content of the metal glaze is 50%, and the formula of the metal glaze is: aluminum oxide 18.34%, silicon dioxide 37.23%, ferric oxide 13.28%, calcium oxide 1.82%, magnesium oxide 0.59%, potassium oxide 4.11%, sodium oxide 5.21%, phosphorus pentoxide 16.93%, titanium dioxide 0.01%, manganese tetraoxide 0.04%, aluminum oxide 0.14%. The metal glaze is reserved in the depressions on the four sides of the...

Embodiment 2

[0011] The process is basically the same as that of Example 1, except that ceramic tiles of 600×600mm are used. There are 162 pits of 5mm, 75 pits of 3mm, and 53 pits of less than 2mm on the green body. The firing temperature is 1190°C. The time is 60 minutes.

Abstract

The invention discloses a production method of ceramic tile with metallic luster partial embellishment surface, which includes such working procedures as biscuit formation, spray glazing, silk screen printing and firing process. Ceramic semi-finished materials are pressed by a ceramic pressing machine into biscuit, and the pressing machine mold is distributed with bulges, thereby forming a plurality of concaves with a diameter less than 5mm on the surface of the pressed biscuit. 400 to 700 concaves are distributed per square meter. After the biscuit with concaves is dried, the surface of the biscuit is spurted evenly with metallic glaze by spray glazing equipment. After dryness, the metallic glaze on the surface of the biscuit is abraded by a frosting machine, and only the metallic glaze remains in the concaves, and then the silk screen printing and the rotary printing are done successively. At length, the ceramic tile is produced from firing under the temperature of 1,190 DEG C for 50 to 60 minutes. The method enables the sunken surface of the ceramic tile to have bright metallic luster, while the plane part is the texture in the style of antiquity. The overall vision is graceful and noble, and the decoration effect is rich.

Description

technical field [0001] The invention relates to a production and manufacturing method of ceramic tiles, in particular to the change and innovation of the surface decoration effect of ceramic tiles. Background technique [0002] In the current architectural ceramics industry, ceramic tile products have gradually developed from a single polished tile to polished tiles, whole body tiles, glazed tiles and other varieties, and there are many mutual penetration and changes between product categories. The surface decoration effect has also developed from a single spray glaze, pour glaze, screen printing, and roller printing to combined printing and multiple printing. , imitation cloth textures and more. With the emergence of metallic glazes, which show metallic luster and color after firing, the decorative effect of ceramic tiles has been further enriched, such as ceramic tiles with imitation metal surface effects. However, due to the large distribution of metal glaze on the bric...
