Problems solved by technology

However, due to the limitation of the performance of the ceramic itself, the strength and toughness of the tile after the thickness is reduced has become the primary problem to be solved.
The strength of traditional ceramics mainly comes from the mullite crystal phase formed after firing, but after the thickness is reduced, the mullite content in the original formula is not enough to meet the requirements for the strength of ceramic tiles in the standard. Problems such as fracture during production and use

preparation example Construction

[0046] A method for preparing high-strength, high-toughness, high-transmittance ultra-thin porcelain tiles, comprising the following steps:

[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]

[0050] S2: Mix the raw materials in S1 and add them into a ball mill for ball milling to obtain a slurry;

[0051] 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 of the mixed raw materials, 120 parts by weight of ball millstone , 50 parts by weight of water, so that the green body raw material can fully contact with the ball millstone in the ball mill, so that the raw material can be crushed better, and the quality of the mixed raw material can be improved.

[0052] Further, the ball millstone at ...

Embodiment 1

[0079] S1: Weigh the raw materials according to the composition ratio of the porcelain tile body;

[0080] Ingredients include:

[0081]

[0082] 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%;

[0083] S3: After sieving the slurry in S2 to remove iron, it stale for more than 24 hours;

[0084] S4: Spray-dry the slurry in S3 to obtain a powder, the moisture content of the powder is 5.5-7.0%, and the powder is stale for more than 24 hours to make the moisture content tend to be consistent;

[0085] S5: After dry pressing the powder in S4, the thickness of the formed green body is 3 mm; glaze the molding material;

[0086] S6: Fire the molding material after glazing, the firing temperature is 1200°C, the firing cycle is 60min, and the ...

Abstract

The invention relates to a high-strength, high-toughness and high-transmittance ultrathin porcelain tile, which at least comprises a green body layer, a decorative layer and a glazed layer, and the green body layer comprises the following component materials in parts by weight: 30-45 parts by weight of alpha-alumina powder; 5-15 parts by weight of calcined talc; 10-20 parts by weight of ultra-white water washed ball clay; 35-45 parts by weight of ultra-white water washed albite powder; 2-5 parts by weight of an inorganic binder; 2-6 parts by weight of a flexibilizer; 0.5-2 parts 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. According to the porcelain tile formed by the invention, the thickness of a finished product is less than or equal to 6mm, the overall light transmittance of a green body is very high, the green body is bright but not dazzling, soft and warm, the effects are rich and changeable in combination with pattern textures on the surface, and the porcelain tile can be applied to decoration of high-end scenes such as television background walls.

Description

technical field [0001] The invention belongs to the technical field of porcelain tiles, and in particular relates to high-strength, high-toughness, high-transparency, ultra-thin porcelain tiles and a preparation method thereof. Background technique [0002] Ceramic production mainly uses natural mineral resources, but natural minerals are non-renewable resources. In order to reduce the consumption of natural mineral resources and respond to the national policy call for energy conservation and emission reduction, the thinning of ceramic tiles is an inevitable trend. However, due to the limitation of the performance of the ceramic itself, the strength and toughness of the tile after the thickness is reduced has become the primary problem to be solved. The strength of traditional ceramics mainly comes from the mullite crystal phase formed after firing, but after the thickness is reduced, the mullite content in the original formula is not enough to meet the requirements for the ...
