China is the largest building and sanitary ceramic producing country in the world and the largest building and sanitary ceramic consumer market in the world, but the overall economic benefit is not high, and the main gap between China and foreign high-end products is the treatment of glaze process and color patterns. In addition, if the glaze surface has a plurality of pores, dirt, bacteria and the like are easily deposited at the defect position in the using process, which is harmful to the health of people, affects the beauty and is difficult to clean. The definition of the pattern and the color purity are directly related to the color development ability of the glaze and the transparency of the glaze. In the production process of ceramic tile products with dark color, the color of the ceramic tile products often limits the implementation of the production process, and the existing color of the ink-jet ink can not meet the ink-jet production, so the existing method usually adopts the combination of ink-jet and screen printing technologies to carry out pattern decoration on the surface of the ceramic tile, but because the oily ink quantity or the fancy glaze quantity of the surface of the ceramic tile is large, the oily ink or the fancy glaze and the water-based glaze slip can often form the phenomenon of mutual repulsion of oil and water when glaze pouring is carried out, so the defects of orange peel, pinholes, concave glaze and the like of the glaze surface of the ceramic tile are generated, the flatness of the glaze surface is influenced, and the color development effect of the glaze patterns of the ceramic tile with dark color is seriously reduced, the definition is low, and.

(7) And (4) firing the ceramic tile obtained in the step (6) at a high temperature.

Preferably, the firing time in step (7) is 70 minutes, and the firing temperature is 1190 ℃ to 1230 ℃.

The precious stone glaze ceramic tile prepared by the method sequentially comprises a blank layer 1, a makeup soil layer 2, a ground glaze layer 3, an ink permeation resistant layer 4, a pattern layer 5, an isolation layer 6 and a protective glaze layer 7 from bottom to top. Wherein the ground coat layer 3 is realized by the following technical scheme.

1. Preparing glaze materials: according to the formula, accurately weighing feldspar with the grain diameter of phi 2.0mm, quartz sand with the grain diameter of phi 0.125mm, kaolin with the grain diameter of phi 0.90mm, calcite, massive Suzhou soil and the like for later use.

The raw materials are put into a ball mill, ball milling is carried out for about 45 hours according to the proportion of 1: 2.6: 0.9 of the materials, balls and water, then the glaze slurry passes through a sieve with the aperture of phi 0.061mm, and the residual sieve is 0.03-0.08 percent and then the glaze slurry is transferred into a slurry storage tank for standby.

2. Glazing: filtering with a sieve with the aperture of phi 0.154mm before glazing, filtering to remove mud residue and impurities, adjusting the specific gravity of the glaze slip to 1.65-1.80, removing dust on the surface of the blank with clear water before glazing, and spraying the ground glaze on the surface of the tile of the cosmetic soil layer by using a bell jar glaze sprayer, wherein the thickness of the glaze layer is 0.5mm-1.0 mm.

Preferably, the ground coat layer 3 comprises the following components in percentage by weight: 26-33% of quartz, 15-25% of calcium carbonate, 10-18% of albite, 10-18% of clay and 20-25% of calcined kaolin. The protective glaze layer 7 comprises the following components in percentage by weight: 78% of frit, 8% of potassium feldspar, 4% of kaolin, 4% of lithionite, 3% of alumina and 3% of quartz powder.

The ink-resistant permeation layer 4 is an organic silicon polymer containing active groups, the ink-resistant permeation layer is sprayed on the surface of the green brick with the silky ground coat layer, and then the ink-resistant permeation layer on the surface of the brick is air-dried through natural air drying for 2 minutes, so that the ink-resistant permeation layer sprayed on the surface of the brick forms a thin permeation-resistant layer, and high-definition reduction of a pattern layer printed by ink-jet printing at the back is ensured.

In the high-definition ink-jet printing layer (namely the pattern layer 5), a dispersant contained in the ink for the ink-jet printer is a polyacrylate dispersant, and the polyacrylate dispersant is specifically at least one of polymethyl acrylate, polyethyl acrylate and tert-butyl polyacrylate. The hyper-dispersant can quickly and fully wet the negative ion particles, and shorten the sanding time for reaching the qualified particle fineness; the content of the negative ion solid particles in the sand grinding material can be greatly improved, and processing equipment and processing energy consumption are saved; and the dispersion is uniform, and the stability is good, so that the final service performance of the dispersion system is obviously improved.

The invention relates to a precious stone glaze ceramic tile, which is characterized in that an isolation layer 6 is additionally arranged between a pattern layer 5 and a fine wear-resistant protective glaze layer 7, and a clear isolation layer is formed by roller printing of printing paste containing water-based tackifying resin. The low-viscosity water-based tackifying resin is used, the viscosity of the printing paste is controlled to be 2000-3000 MPa.S, the problem that the isolation layer is easy to leak due to too low viscosity is solved, and when the viscosity is too high, the glaze layer is easy to roll under a high-temperature condition to peel off the brick surface, so that the problem of large-area glaze shortage is generated after sintering; the low-viscosity water-based tackifying resin can be completely melted under the condition of firing at 300 ℃, and the clear isolation layer after firing has stable structure and has no influence on the performance of the product.

Further, the paste of the isolation layer 6 further comprises sodium oxide, which comprises the following raw material components in percentage by mass: 10% sodium oxide, 3% aqueous tackifying resin, 2% ethylene glycol, 2% zinc oxide, 1% anti-blocking agent and 82% water. The sodium oxide has good fluxing action and can further reduce the glaze temperature, thereby being beneficial to color development, improving the pattern effect of the glaze and enabling the decorative pattern of the glaze of the ceramic tile to be more clear and fine, therefore, the aqueous tackifying resin and a certain amount of sodium oxide are adopted in the formula of the printing paste, and the viscosity of the printing paste and the stability of the color development effect of the glaze can be effectively controlled by adjusting the proportion of the aqueous tackifying resin and the sodium oxide according to the specific conditions of the color depth and the printing effect of the ceramic tile with deep color. For example, when the tile has a black color, the isolation layer 6 comprises the following components in percentage by mass: 10.9% sodium oxide, 4.1% aqueous tackifying resin, 2% ethylene glycol, 2% zinc oxide, 1% anti-blocking agent and 80% water; when the color of the tile surface is light gray, the mass percentage of the isolation layer 6 is as follows: 8% sodium oxide, 2.6% aqueous tackifying resin, 2% ethylene glycol, 2% zinc oxide, 1% anti-blocking agent and 84.4% water.

Further, the aqueous tackifying resin of the seal ink of the isolation layer 6 is any one of a transfer rosin resin or an acrylate. The invention adopts the low-viscosity water-based tackifying resin, preferably acrylate to control the viscosity of the printing paste, thereby not only avoiding the leakage condition, but also having stable structure and no glaze shortage phenomenon under the high-temperature firing condition, and ensuring that the protective glaze layer at the uppermost layer is more smoothly distributed.

As mentioned above, the fine stone glaze ceramic tile manufactured according to the invention has high-definition patterns and smooth and fine glaze surface, has smoother and finer glaze surface effect, has antifouling and wear-resisting properties, and is a ceramic tile product with great practical value.
