2. And spraying protective glaze on the dried brick blank, and firing in a kiln to obtain the plain light micro-etched wood grain ceramic tile.

The production process specifically comprises the following steps:

1. mixing 3-5 parts by weight of quartz, 5-8 parts by weight of high-temperature frit, 10-13 parts by weight of air knife soil, 1 part by weight of albite, 5 parts by weight of kaolin, 10-15 parts by weight of barium carbonate, 18-20 parts by weight of calcined kaolin and 35-40 parts by weight of talc, grinding and ball-milling to obtain glaze slip, and obtaining the ground glaze for later use.

2. Taking 5-10 parts by weight of albite, 20-30 parts by weight of potash feldspar, 1-5 parts by weight of kaolin, 1-10 parts by weight of calcined kaolin, 1-10 parts by weight of calcite, 1-3 parts by weight of dolomite, 1-3 parts by weight of calcined talc, 5-10 parts by weight of wollastonite, 5-10 parts by weight of alumina, 5-15 parts by weight of barium carbonate, 5-10 parts by weight of quartz and 5-10 parts by weight of zinc oxide, mixing, grinding and ball-milling to obtain glaze slurry, and obtaining the protective glaze for later use.

3. Taking 20-30 parts by weight of ceramic micro powder, 5-10 parts by weight of quartz micro powder, 10-15 parts by weight of ethylene-acrylic acid copolymer, 15-25 parts by weight of ethyl acetate, 5-8 parts by weight of glycerol and 10 parts by weight of cyclohexanone, grinding into a plurality of parts according to the requirements of functional ink, and adding 2-10 parts by weight of different pigments. Preferred in the present invention are Esca-Gras, Itada, highly oily functional inks.

The raw material particle size and texture requirements of the functional ink are well known to those skilled in the art and are not therefore described in a cumbersome manner.

4. Taking 20-30 parts by weight of clay, 20-30 parts by weight of quartz sand, 10-20 parts by weight of feldspar, 20 parts by weight of waste ceramic broken bricks and 10 parts by weight of kaolin, crushing, ball milling, deironing, pulverizing, pressing and molding, and predrying to obtain a brick blank. The process for preparing the brick blank is the same as the prior art and is not described redundantly here.

5. Preparing the prepared ground glaze into slurry, spraying the ground glaze on the brick blank, and spraying the ground glaze in an amount of 300-350 g/square meter of the brick blank.

6. Then, the pattern is sprayed and printed by using glaze of the conventional technology according to the requirement, and the pattern is a basic pattern and can be adjusted according to the actual situation. The structure of the pattern is the same as that of the prior art, is a flat one-layer pattern structure and does not have concave-convex characteristics.

7. Then functional ink is sprayed, a 6-channel ink-jet machine is used for spraying the functional ink with the color of 3, the ink output of each channel is 40 g/square, the functional ink with the same color is sprayed in every two channels, and then the functional ink is dried for 25min at the temperature of 100 ℃ and 150 ℃.

8. And spraying a protective glaze, wherein the spraying amount of the protective glaze is 250-300 g/square meter, drying the brick blank, delivering the brick blank to a kiln for firing, processing to obtain the plain light micro-etched wood grain ceramic tile, and inspecting and classifying the ceramic tile to leave the factory.

In the technology of the invention, the base coat is sprayed on the blank body firstly, the base coat is water-based, then the pattern is sprayed, and then the high-oil functional ink is sprayed on the blank body by utilizing 6 channels according to the designed pattern. The pattern is fused in the ground coat, and the high-oiliness functional ink floats on the ground coat to form an oil-water separation state.

And then drying at the temperature of 100-150 ℃ for 25min, wherein during the drying process, barium carbonate is dissolved, the luster of the ground glaze is gradually eliminated, and a bump structure is formed between the high-oil functional ink and the ground glaze after partial moisture is evaporated, wherein at the moment, the ground glaze and the functional ink are not completely dried.

And then, spraying protective glaze on the functional ink of the brick blank, wherein the protective glaze is water-based, and then firing under the condition of the conventional technology and at the temperature of 1200-1250 ℃.

The thickness of each layer of structure on the embryo body is not thick, the process time of each layer for generating the effect is very close, and the drying condition is described according to the number of times in sequence at the temperature, and the method specifically comprises the following steps: the first layer is the protective glaze, the functional ink floats on the protective glaze, the next layer is dried, namely the functional ink layer, and the ground glaze also enters a dry state quickly because the ink is oily and the drying time and temperature are higher than those of water. At the moment, relative to the thickness of the ceramic tile, the position with the functional ink protrudes upwards, the barium carbonate of the ground coat eliminates the luster of the pattern and the ink, so that the saw-tooth feeling of the whole ceramic tile structure is obvious, particularly, the feeling of hand touch is obvious, concave-convex textures consistent with the design pattern of a computer are formed, the annual ring feeling on the ceramic tile body is also obvious, and the observation under the side light is basically consistent with the solid wood.

The glaze and the functional ink used in the invention can generate good oil-water separation effect, so that the fired product has concave-convex textures with different luminosity.

The meaning of the plain micro-engraved wood grain is that the ceramic tile uses matte color and bright color as the color of the functional ink, and forms a light plain color with a soft light and wood grain result after the ceramic tile and glaze are fired, so the ceramic tile is called as the plain micro-engraved wood grain ceramic tile.

Under the influence of the bright barium carbonate, the bright effect is fused and becomes soft light.

The invention is described in detail below by means of a number of examples:
