Problems solved by technology

[0002] With the development of society and the improvement of consumers' material and cultural living standards, traditional ceramic tiles mainly focus on conventional physical and chemical properties, and do not have high requirements on the whiteness and light transmittance of the body, which can no longer meet the growing aesthetic needs of consumers. ; High whiteness and high light transmittance ceramic tile bodies are favored by consumers because they can better express the color of the tile surface
[0003] Traditional ceramic tiles basically do not consider the light transmission performance of ceramic tiles, which can greatly enrich the decorative effect of ceramic tiles; in addition, traditional ceramic tiles mainly increase the whiteness of the body through the addition of zirconium silicate, usually at 55-65° Or so, but adding too much zirconium silicate will bring the risk of high radioactivity index to the tiles, which has potential safety hazards, and the high cost of zirconium silicate will increase the production cost
[0004] CN1286770C discloses a kind of ultra-white porcelain brick, in order to pursue whiteness, the flux class raw material in its formula is relatively low, and the refractoriness of formula is higher, approaches the upper limit of temperature of the existing kiln in the industry, is not suitable for industrialized batch production, and Does not reflect light transmission characteristics

[0047] S1: Weigh the raw materials according to the composition ratio of the porcelain tile body; pound the materials one by one according to the formula ratio of the porcelain tile body, including

[0048]

[0049] The main component of burnt talc is partial talc.

[0050] 4-10 parts by weight of albite powder;

[0051] The molecular formula of albite is Na 2 O·Al 2 o 3 ·6SiO2 2 .

[0052] 2-5 parts by weight of inorganic binder;

[0053] Strengthening agent 0.2-1 weight part;

[0054] Debonding agent 0.1-0.5 parts by weight.

[0055] S2: Mix the raw materials in S1 and add them into a ball mill for ball milling to obtain a slurry;

[0056]Further, during ball milling in S2, the mass ratio of the mixed raw materials, ball millstone and water is 1:1.2:0.5-0.8; in some embodiments, weigh 100 parts by weight o...

Embodiment 1

[0082] S1: Weigh the raw materials according to the composition ratio of the porcelain tile body;

[0083] Ingredients include:

[0084]

[0085] S2: Mix the raw materials in S1 and add them to a ball mill for ball milling, and control the mass ratio of the mixed raw materials, ball millstone and water to 1:1.2:0.5 to obtain a slurry; control the sieve residue of a 325-mesh analytical sieve in 100g of slurry The amount is below 3%;

Abstract

The invention relates to a zirconium-free high-whiteness high-transmittance porcelain tile suitable for industrial production. A green body of the porcelain tile comprises the following component materials in parts by weight: 12-18 parts of alpha-alumina powder, 22-28 parts by weight of quartz sand, 12-18 parts by weight of ultra-white water-washed ball clay, 25-45 parts by weight of calcined talc, 4-10 parts by weight of albite powder, 2-5 parts by weight of an inorganic binder, 0.2-1 part by weight of a reinforcing agent, and 0.1-0.5 part by weight of a dispergator. The invention also relates to a preparation method of the porcelain tile. The whiteness of the finishedporcelain tile is 75 degrees or above, and the volume expansion coefficient is 220 * 10<-7> or below; and when the porcelain tile is used for decoration of a background wall and the like, transmitted light is bright but not dazzling, and the overall effect is rich and changeable by matching with the color texture of the surface of the green body.
