The light-transmitting brick with the white radial crystal pattern effect not only improves the grade of products, but also enriches the decorative effect of the architectural ceramic glazed brick.

FIG. 1 shows the process for preparing the light-transmitting ceramic tile of the present invention.

First, a light-transmitting powder is prepared.

In some embodiments, the raw material composition of the light-transmitting powder may include: and (2) grinding potassium feldspar with water according to mass percentage: 10-15%, albite: 25-35% of ultra-white potassium sand: 5-20% of pyrophyllite: 5-20% of calcined kaolin: 0-10%, ultra-white ball clay washing: 5-15% of ultra-white washing mud: 5-15% of talc mud: 1-3%, wollastonite: 0 to 1 percent.

The raw materials are weighed according to the proportion, the raw materials are put into a ball mill for ball milling to obtain the light-transmitting slurry, and the light-transmitting slurry is powdered (for example, powder is sprayed by a spray tower) to obtain the light-transmitting powder. The moisture range of the light-transmitting powder is controlled to be 7.5-8.5%, which is beneficial to the press molding of a press and does not influence the light-transmitting performance of the blank.

The chemical composition of the light-transmitting powder material can comprise: by mass percent, SiO ₂：63.0～68.0％、Al ₂O ₃：21.0～24.0％、Fe ₂O ₃：0.1～0.3％、TiO ₂：0～0.2％、CaO：0.7～1.0％、MgO：0.5～1.0％、K ₂O：2.0～3.5％、Na ₂O: 3.0-4.0%, loss on ignition: 4.0 to 5.5 percent. The light-transmitting blank has high aluminum content and strong deformation resistance, the whiteness of the blank after burning is 70 to 75 degrees, and the higher the whiteness is, the better the light-transmitting performance is, so that the blank has higher transmittance.

In some embodiments, the particle composition of the light-transmitting powder is: 30 meshes below: less than or equal to 0.5 percent, 30-60 meshes: 55-65%, 60-80 mesh: 25-35%, more than 80 mesh: 6-12%. The sintered compact has high density and excellent light transmittance, and is favorable for press forming.

And pressing, molding and drying the light-transmitting powder to obtain the light-transmitting green body layer 1.

The light-transmitting blank has high whiteness, and overglaze can be omitted. Usually, the chemical composition of the overglaze is close to that of the blank body, and the zirconium silicate is added to cover the bottom color of the blank body, improve the whiteness of the blank body and promote the color development of the ink to be bright. The whiteness of a common blank body is low, and a cover glaze is needed to cover the bottom color of the blank body, so that the whiteness is improved, and the color development of the ink is promoted to be bright. Because the light-transmitting blank has high whiteness, the surface glaze is not applied, and the ink-jet printing pattern can be directly carried out on the light-transmitting blank after drying.

The green body may be dried in a drying kiln. The drying temperature can be 200-250 ℃, the drying time can be 50-75 min, and the moisture of the dried blank is controlled within 0.5%.

And ink-jet printing a pattern on the ceramic blank. The ink can be printed by a digital ink-jet printer. The ceramic ink used may be blue, reddish brown, orange, golden yellow, lemon yellow, black, red, etc. The specific decorative pattern, texture and color effect are determined according to the design requirements.

And then applying the white radial crystal flower dry grain glaze disclosed by the invention on the surface of the blank after ink-jet printing. The glazing amount of the white crystal flower dry grain glaze can be 800-1000 g/m ². The glazing amount of the dry particle glaze is small, and the defects of uneven glaze surface and exposed polishing already occur in the polishing process; the dry grain glaze has more glazing amount, the number of pores is more and large after the glaze surface is polished, and the white spots of the glaze surface are more. Application of white crystal flower dry grain glazeThe method can be used for distributing dry granules by a common dry granule machine or a digital dry granule machine or distributing dry granules by a belt type distributing machine.

And applying a fixing agent on the surface of the brick coated with the white crystal flower dry grain glaze, so as to fix the white crystal flower dry grain glaze. The material of the fixing agent is not particularly limited, and may be a dry pellet fixing agent known in the art. In one embodiment, a glue fixative is used. The specific gravity of the dry particle fixing agent is 1.01-1.02, the specific gravity is low, the water jet cutting machine can spray the fixing agent conveniently, the atomization is good, and a glaze surface pit cannot be caused by too large impact force of sprayed liquid drops. The dry granules can be fixed by spraying a mist-like dry granule fixing agent with a high-pressure water jet machine. The application amount of the dry particle fixing agent can be 250-300 g/m ²And spraying a small amount of fixing agent to completely fix the dry granules under the condition of ensuring that the moisture content of the green bricks is as low as possible. The pressure of the high-pressure water jet cutting machine can be controlled to be 9-14 Mpa.

The resulting ceramic body may then be dried, for example, using a glaze line kiln. The temperature of the drying kiln is controlled to be 150-200 ℃, the drying time can be 5-15 min, and the moisture after drying is controlled to be within 1.0%.

Then, firing is carried out, for example, low-temperature quick firing in a roller kiln. The sintering period can be 100-150 min, and the maximum sintering temperature range can be 1190-1210 ℃.

After firing, polishing, edging, grading, packaging and warehousing can be carried out. The polishing manner may be a full polishing process.
