Problems solved by technology

However, due to the lack of the bright and bright features of polished tiles, glazed tiles have good anti-slip effects, but their colors and textures are too old and rough, which are not accepted by ordinary consumers. still relatively low

Embodiment 1

[0019] (1) Brick forming

[0020] The powder is pressed through a conventional molding die to produce adobes of specified specifications, and the thickness is required to be 10±0.3mm.

[0021] (2) Glaze printing

[0022] After the adobe is dried, spray a layer of primer on the surface of the adobe, then use screen printing to print twice according to the set pattern, and then use roller printing to print twice. The total number of printings is 4 times, and then Apply a layer of dry powder transparent glaze with a glaze thickness of 1.05mm. On this layer of transparent glaze, the pattern corresponding to the printed pattern is printed into a glaze layer with obvious concave and convex contours. The depth of the concave surface is 0.7-0.8mm in different shades.

[0023] (3) Brick firing

[0024] After the glazed and printed bricks are covered with a layer of ground slurry, they are sent to a roller kiln for firing at a high temperature of 1200 °C.

[0028] (1) Brick forming

[0029] The powder is pressed through a conventional molding die to produce adobes of specified specifications, and the thickness is required to be 11.5±0.3mm.

[0030] (2) Glaze printing

[0031] After the adobe is dried, spray a layer of primer on the surface of the adobe, and then use screen printing to print twice according to the set pattern, and then use screen printing to print three times. The total number of printings is 5 times, and then Apply a layer of dry powder transparent glaze with a thickness of 0.9mm. The transparent glaze on this layer is printed according to the pattern corresponding to the printed pattern to form a glaze layer with obvious concave and convex contours. The depth of the pit surface is 0.6-0.75mm.

[0032] (3) Brick firing

[0033] The bricks that have been glazed and printed are sent to the roller kiln for firing at a high temperature of 1220°C.

[0037] (1) Brick forming

[0038]Press the powder into a flat adobe of specified specifications through a conventional molding die, and the thickness is required to be 10±0.3mm.

[0039] (2) Glaze printing

[0040] After the adobe is dried, spray a layer of primer on the surface of the adobe, then use roller printing to print three times according to the set pattern, then spray a layer of transparent glaze, and then use roller printing to print twice. The total number of printings is 5 times, and then a layer of dry powder transparent glaze dry powder with a glaze layer thickness of 1.0mm is applied. The transparent glaze on this layer is printed into a glaze layer with obvious concave and convex contours according to the corresponding patterns of in-glaze color patterns. The depth of the pit surface varies from 0.6 to 0.7mm.

Abstract

The invention relates to a ceramic brick manufacturing process with concave-convex polished in-glaze decoration, which comprises the following steps: on the basis of the traditional process, firstly, applying a layer of ground coat and a first layer of transparent glaze on the surface of a green brick; then, printing for 4-7 times on the first layer of transparent glaze; stacking dry powder transparent glaze of which the thickness is 0.7-1.2mm on the printing pigment, and carrying out corresponding distribution according to the printed pattern textures to form concave-convex contour patterns; baking at high temperature of 1200-1230 DEG C, and then, polishing and grinding the plane of the baked green brick by adopting a hard grinding head, wherein the polishing and grinding depth is controlled at 0.1-0.3mm; and polishing and grinding the plane by adopting an elastic soft grinding head, and carrying out micro-polishing treatment on the concave pit surface of the green brick, which sags and can not be processed. The process can enable the surface of a ceramic brick to have bright and clean decorative effect of a polished brick and simultaneously have exquisite textures, thin lines, smooth and hazy tactile sensation and bright and luxuriant color, and the patterns below the glaze layer generate strong visual three-dimensional effect, thereby innovating the style of ceramic brick products.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to the improvement process of glazed decorative ceramic tiles. Background technique [0002] Polished tiles are one of the mainstream products of ceramic wall and floor tiles. Their surface is smooth and bright, and their texture is hard and wear-resistant, so they are favored and loved by consumers, and the market awareness is quite high. However, behind the bright polished bricks, there are also many crises hidden. 1. The requirements for raw materials are quite high, especially the selection of high-quality clay and high-whiteness porcelain sand (feldspar with low iron content) is very strict; 2. The cutting volume of cold processing is relatively large, and the utilization rate of general raw materials is only 85%. , and it needs to consume huge power (polishing process) and generate a large amount of solid waste; 3. The product style is relatively small, and cur...
