Problems solved by technology

The former is easy to make small pits on the surface of the dry powder when applying glue. At the same time, the dry powder is easily agglomerated and pilled by the surface tension of the liquid droplets, and it is also easy to produce pits, resulting in uneven dry grain surface after subsequent firing, reducing Product excellent rate
Although these problems can be avoided in the latter process, in order to save costs, the dry granular glaze slurry needs to be recycled in the process, so for the dry particles with a large specific gravity, precipitation is very easy to occur, so when the glaze slurry is applied, the brick adobe There will be uneven distribution of dry particles on the surface
Even through manual intervention, such as enhanced stirring, it is still impossible to completely solve the problem of uneven product surface effects in mass production

preparation example Construction

[0041] The present application provides a method for preparing dry grain decorative ceramic tiles, which includes: pre-treating the bricks; applying dry grains, water-retaining wetting agent and glaze slurry to the surface of the bricks after the pretreatment, and post-processing to obtain dry grain decorative ceramic bricks ; Wherein, the water-retaining wetting agent includes transparent protective glaze, suspending agent and water.

[0042] In the prior art, two common preparation techniques are used to prepare dry grain decorated ceramic tiles. For the dry process, in order to reduce the production cost, it is necessary to reduce the amount of dry granules as much as possible, but it is also necessary to ensure the smoothness of the glaze firing, so the particle size of the dry granules is generally controlled between 60 mesh and 160 mesh. Some even reach 200 mesh. After distributing these dry powdered dry particles on the surface of the bricks, another layer of glue must...

Embodiment 1

[0060] This embodiment provides a kind of dry granular decorative ceramic tile, which is prepared by the following preparation method, including:

[0061] (1) Spread glaze on the surface of the brick, and then use inkjet printing to decorate the pattern;

[0062] (2) Apply a layer of dry granules on the surface of the adobe in step (1) with a dry granule distribution machine, wherein the dry granules include mixed dry granules of crystal flash dry granules and once-fired dry granules, and the application amount is 150g / m 2 , the particle size of crystal flash dry particles is 80 mesh to 150 mesh, and the chemical composition of crystal flash dry particles is based on mass percentage, including ZrO 2 : 6%, SiO 2 : 65%, Al 2 o 3 : 5%, B 2 o 3 : 10%, Na 2 O: 11%, Li 2 O: 3%; the chemical composition of the once-burned dry grain is calculated by weight percentage, including: SiO 2 : 58%, Al 2 o 3 : 10%, CaO: 10%, MgO: 1%, ZnO: 11%, BaO: 1%, K 2 O: 8%, Na 2 O: 1%, of wh...

Embodiment 2

[0067] This embodiment provides a kind of dry granular decorative ceramic tile, which is prepared by the following preparation method, including:

[0068] (1) Spread glaze on the surface of the brick, and then use inkjet printing to decorate the pattern;

[0069] (2) Apply a layer of metal dry particles on the surface of the adobe in step (1) with a dry particle distribution machine, wherein the metal dry particles include a mixture of metal copper powder and primary fired dry particles, and the application amount is 200g / m 2 , the metal copper powder accounts for 5% of the total mass of the mixture, and the chemical composition of the once-fired dry particles is calculated by mass percentage, including: SiO 2 : 58%, Al 2 o 3 : 10%, CaO: 10%, MgO: 1%, ZnO: 11%, BaO: 1%, K 2 O: 8%, Na 2 O: 1%;

[0070] (3) Spray water-retaining wetting agent on the surface of the adobe in step (2) with a high-pressure glaze spray cabinet, and the application amount is 130g / m 2 , The water...

Abstract

The invention discloses a dry-particle decorative ceramic tile and a preparation method thereof. The preparation method specifically comprises the following steps: pre-treating a green brick; and sequentially applying dry granules, a water-retaining wetting agent and glaze slip on the surface of the green brick subjected to pretreatment, and then performing aftertreatment, wherein the water retention wetting agent comprises transparent protective glaze, a suspending agent and water. The dry- particle decorative ceramic tile can be prepared by using the preparation method. The preparation method provided by the invention solves the problems that surface pits are easy to appear in a dry process and the like, also solves the problems of precipitation and segregation of the dry particles with large specific gravity in the liquid glaze slip, ensures the surface effect of the product decorated by the dry particles, improves the superior rate of the product, and is suitable for industrial large-scale production. And the dry- particle decorative ceramic tile prepared by the preparation method is excellent in product performance, stable in surface decorative effect and free of obvious defects.

Description

technical field [0001] The present application relates to the technical field of ceramic tile production and manufacturing, in particular to a dry granular decorative ceramic tile and a preparation method thereof. Background technique [0002] Due to the wide variety of dry grains, there are many different forms of dry grain decorative ceramic tiles, such as crystal flash dry grains, metal dry grains, transparent dry grains, colored dry grains, etc., which can present different effects. It can show glass quality, looks transparent like glass, and has excellent decorative effect. After firing, the tiles are polished, the glazed surface has high flatness, low water absorption, and good material performance, which is deeply loved by consumers. [0003] In the existing production process of dry granule decorative ceramic tiles, there is a process of directly applying dry powder and dry granules on the surface of the tiles, and then applying a layer of glue for firing, and there...
