Its weak point is: the main purpose of the production technology of this imitation marble ceramic thin plate is to provide a kind of ceramic thin plate product with the appearance similar to marble texture and color, but its manufacturing process aspect is compared with the ceramic tile of common thickness. Significant improvement, after the thickness of the product is reduced, although the modulus of rupture of the product still meets the national standard, its impact resistance performance is reduced, that is, the toughness is insufficient

Embodiment 1
[0031] The high-toughness ceramic thin plate comprises three layers from top to bottom: a decoration layer, a green body layer and a coating layer.
[0032] The back side of the green body layer is composed of continuous planes and discontinuous pits. The continuous plane is the reference plane of the back side of the green body layer and is on the same horizontal plane. The pits are hemispherical pits with a radius of 0.3 mm, the interval between the pits is 4 mm, and they are recessed toward the surface of the green body based on the continuous plane, and the depth of the recess is the radius of the hemispherical shape. The green body layer is formed by dry pressing.
[0033] The body layer consists of 10 parts by weight of flat sand, 12 parts of Xinfang sand, 21 parts of water scrub, 22 parts of Fushun stone powder, 12 parts of ball clay, 15 parts of black mud, 5 parts of kaolin, 3 parts of magnesia mud share.
[0034] The covering layer is under the green body layer, in...
Embodiment 2
[0061] The high-toughness ceramic thin plate and its manufacturing method comprise three layers from top to bottom: a decoration layer, a green body layer and a coating layer.
[0062] The back of the green body layer is composed of a continuous plane and intermittent concave points; the continuous plane is the reference plane of the back of the green body layer and is on the same level. The pits are hemispherical pits with a radius of 0.5 mm, the interval between the pits is 5 mm, and they are recessed toward the surface of the green body based on the continuous plane, and the depth of the recess is the radius of the hemispherical shape.
[0063] The green body layer is pressed and formed by roll forming.
[0064] The body layer consists of 8 parts by weight of flat sand, 10 parts of Xinfang sand, 18 parts of water scrub, 20 parts of Fushun stone powder, 13 parts of ball clay, 20 parts of black mud, 6 parts of kaolin, 5 parts of magnesia mud share.

Abstract
The invention relates to a high-toughness ceramic thin plate and a preparation method thereof. The ceramic thin plate comprises a decorative layer, a blank layer and a coating layer which are compounded together from top to bottom. The lower part of the ceramic thin plate is covered with a reticular film layer, the reticular film layer is adhered to the bottom, consisting of continuous planes anddiscontinuous concave points, of the blank layer, and the reticular film layer and the bottom of the blank layer are tightly adhered together. The preparation method comprises the following steps: (1)pressing and forming blank powder according to the required size and thickness to obtain the blank layer; (2) drying the blank in a drying kiln at 130-160 DEG C for 90-180 minutes; (3) performing glaze spraying and ink jet processes on the dried blank layer to form the decorative layer in a production glaze line; (4) firing the brick blank with the formed decorative layer in a roller kiln to obtain a finished product, wherein the firing temperature is 1140-1180 DEG C, and the firing time is 80-150 minutes; (5) polishing and edging the burnt finished product; and (6) fixing the coating layer under the blank layer of the edged finished product.
Description
technical field [0001] The invention relates to the technical field of ceramics, in particular to a high-toughness ceramic thin plate and a preparation method thereof. Background technique [0002] Ceramic thin plate is a development direction in the industry, which is consistent with the direction of green environmental protection and resource conservation advocated by the country, and has broad prospects. Europe has formed a complete ceramic thin plate production system more than ten years ago, and can produce thin plate products with a thickness of less than 6mm. However, in China, on the one hand, the pressing technology has been relatively backward, and the floor tiles need to have a larger thickness to meet the strength requirements; on the other hand, consumers have insufficient awareness, thinking that the thicker the floor tiles, the better the product quality. Therefore, for a period of time, the thickness of domestic ceramic floor tile products has been relativel...
