Boundary effect infiltrated glaze of imitating natural stone texture and manufacture method

Abstract

The present invention discloses one kind of fancy glaze with the boundary effect similar to natural stone and prepared based on the chemical principle of SnCl2+H2O=[Sn(OH)Cl2]+H+. The fancy glaze is prepared with SnCl2, sodium citrate, HCl, glycol, carboymethyl cellulose and water in certain weight proportion, and through the steps of compounding water solution of SnCl2, adding sodium citrate and dissolving, and thickening with glycol solution of carboymethyl cellulose to form the fancy glaze. The fancy glaze with whitening effect may be used to replace white fancy glaze prepared with ammonium fluorozirconate colloid solution, and has the effects of lowering loss, raising quality, raising the decoration effect of polished ceramic tile, etc.

Description

technical field [0001] The invention relates to raw materials of ceramic tiles and a preparation method thereof, more specifically to a bleed glaze imitating the boundary effect of natural stone textures for surface decoration of porcelain polished tiles and a preparation method thereof. Background technique [0002] Porcelain polished tiles are popular in the wall and floor tile market because of their excellent decorative effect and durability. Among all the series of porcelain polished tiles, the series of bleed polished tiles is particularly prominent. The investment in equipment is small, the production cost is relatively low, and the output of the same production line is more than 30% higher than that of other polished tile series products, so the sales unit price is low, and it is easier to be accepted by consumers. With these advantages, Over the years, the seepage polished tiles have occupied more than half of the polished tile market with its high cost performance....

AI Technical Summary

Problems solved by technology

However, there are still several serious deficiencies: First, in terms of decorative effect, it is not satisfactory because of its characteristics, in the process of production penetration, there is a strong lateral diffusion, resulting in the diffusion of patterns. Larger, giving people a more flimsy feeling

Second, there are also great shortcomings in its production and use. The production of white bleed glaze often leads to cracks or even fried bricks in polished tiles, which directly leads to the reduction of production quality.

After the 40 or 60-mesh screen printing glaze, the amount of flower glaze per unit area on the surface of the green body will be too large, and the seepage-promoting water sprayed later will still not be able to remove the ammonium fluorozirconate on the surface of the green body. The colloid is completely dissolved, and finally stays on the surface of the green body, causing the local water content of the green body to be too high, leaving hidden dangers of brick cracking and brick blasting in the subsequent high-temperature firing process
