Problems solved by technology

[0002] Although the existing porcelain polished tiles have fancy styles, various textures and are wear-resistant, their surfaces are all polished and ground. The visual effect is still too cold and dazzling, and the anti-skid effect is not good.
Another type of glazed antique brick has a visual effect on the surface of European style. Although the anti-skid effect is good, its color and texture are too old and rough, which is not acceptable to ordinary consumers.

Embodiment 1

[0013] (1) Shaped adobe

[0014] Adobes with many irregularly distributed concave and convex surfaces are pressed through conventional adobe molding dies. The shapes of the concave and convex surfaces are also irregular, and the depths between them are all below 1mm and have different shades. The area is 14mm 2 Below and in different sizes.

[0015] (2) Printing and glazing

[0016] After the adobe is dried, the adobe with concave-convex texture is printed, colored and glazed according to the set pattern.

[0017] (3) Burned into adobe

[0018] After the glazed bricks are dried, they are sent to a roller kiln for firing at 1250°C.

[0019] (4) Polished adobe

[0020] After the brick is fired, put it into a polishing machine with an elastic grinding head for glaze polishing until the depth of the concave surface is reduced to less than 0.7mm, and the polished area accounts for 50-60% of the entire brick area. Inspection, packaging, and storage become finished product.

Embodiment 2

[0022] (1) Making brick adobe forming molds

[0023] The core veneer of the forming mold is a rubber and plastic sheet. Firstly, a mold for producing rubber and plastic sheets is manufactured. The steel working surface of this mold is etched with a pre-designed pattern by chemical processing. The area of ​​each concave and convex surface is 14mm 2 The following and different sizes, the depth of each convex surface relative to each concave surface is less than 0.9mm and the depth is different. Then, use this steel mold to produce rubber and plastic sheets with concave and convex textures, and then manufacture brick molding molds according to conventional processes.

[0024] (2) Shaped adobe

[0025] After the raw material formula is carried out through the conventional ceramic production process, the ball milling and spray drying processes are used to make powder, the forming mold manufactured by the above method is used to press the adobe with concave and convex surfaces.

Embodiment 3

[0035] (1) Shaped adobe

[0036] Through the conventional ceramic production process, the raw material formula, ball milling, and spray drying process are made into powder, and the brick is pressed with a molding die, so that the depth between the concave and convex surfaces of the brick surface is less than 0.6mm and the depth is different. Each concave and convex surface The area of ​​the 10mm 2 Below and in different sizes.

[0037] (2) Blank glaze separator

[0038] After the adobe is dried, the brick adobe with concave-convex texture is printed and registered first, and the transfer printing process is used to apply a glaze separator, which is paint.

[0039] (3) Multiple glaze spraying, printing glaze

[0040] Spray glaze and print glaze on the brick surface with concave-convex texture and glaze separator.

[0041] (4) Burned into adobe

[0042] After the glazed bricks are dried, they are sent to a roller kiln for firing at 1230°C.

[0043] (5) Polished adobe

Abstract

The invention discloses a method for producing the ceramic brick with concave-convex pattern on surface, which comprises: using mould to form the brick blank with concave-convex surface, while the depth of each convex and concave surface is lower than 1mm and different, and the area of each surface is lower then 15mm2 and different; drying, printing pattern, glazing, high-temperature firing; using flexible grinder to process micro-polishing on the brick blank to reduce the depth of each concave surface to lower than 0.7mm and the polished area is 40-70% of all, and the left un-polished area is 60-30% of all. Said invention can make the brick surface into polished glaze surface, un-polished glaze surface and polished blank surface, etc, with different concave-convex pattern.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to the manufacturing process of ceramic bricks with leather-like surface effect. Background technique [0002] Although the existing porcelain polished tiles have fancy styles, various textures and are wear-resistant, their surfaces are all polished and ground, so the visual effects are still cold and dazzling, and the anti-skid effect is not good. Another type of glazed antique brick has a European style as its surface visual effect. Although the anti-skid effect is good, its color and texture are too old and rough, which is not acceptable to ordinary consumers. At the same time, there are quite a few wall and floor tiles with stone-like and wood-like styles that are popular at present, but they generally focus on tough and vicissitudes of style in terms of visual effects, while imitation leather, especially imitation sheepskin, has a soft style. There are no soft, ...
