[0002] In the field of ceramic tiles, marble tiles and the like, the general definition of ceramic tile gloss is bright light, high light, soft light, waxy light, etc. Based on the principle of adapting to the market with high-quality new products, we have conducted market research and investigation to understand customer needs, and combined with the company's development policy, after years of research, on the basis of ensuring the quality of ceramic tiles, we have improved the performance of ceramic tiles in all aspects, taken differentiated categories, improved the core strength of products, and broke through the traditional ceramic tile production barriers. The waxy gloss is born leisurely, which conforms to people's aesthetic and visual experience, has a simple process, and improves production efficiency.

[0003] Therefore, the research on super translucent screen-printed brush-polished jade-like luster ceramic tiles has a positive market prospect. To this end, we propose a semi-transparent screen-printed brush-polished jade-like luster ceramic tile and a preparation method thereof. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the present invention provides a semi-transparent screen-printed brush-polished jade-like luster ceramic tile and a preparation method thereof. The prepared ceramic tile has the advantages of jade-like luster, a new brush-polishing process, a smooth glaze surface, a semi-transparent and rounded texture, more realistic colors, delicate hand feel, good thermal insulation performance, excellent acid and alkali resistance, and good anti-fouling and anti-slip effects.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A semi-transparent screen-printed brush-polished jade-fat gloss ceramic tile comprises a body and a surface glaze layer, a marble pattern layer, a semi-transparent jade-fat marble glaze layer, and a brush-polishing layer sequentially attached to the body;

[0007] The glaze layer comprises the following raw materials in parts by weight:

[0008] 5-9 parts of limestone, 15-20 parts of quartz, 5-10 parts of wollastonite, 30-42 parts of potassium feldspar, 7-10 parts of kaolin, 1-5 parts of barium carbonate, 4-6 parts of zinc oxide, 1-5 parts of aluminum oxide, 15-20 parts of zirconium silicate, 0.2-0.29 parts of methyl cellulose, and 0.35-0.55 parts of sodium tripolyphosphate;

[0009] The semi-transparent jade marble glaze layer comprises the following raw materials in parts by weight:

[0010] 25-30 parts of lithium feldspar, 5-20 parts of lithium porcelain stone, 6-8 parts of talc, 5-10 parts of ball clay, 6-11 parts of zinc oxide, 15-30 parts of silicon aluminum boron crystal frit, 2-5 parts of fluorite, 1-5 parts of corundum, 1-2 parts of lithium carbonate, 5-10 parts of quartz, 20-40 parts of polyvinyl chloride methyl paste, and 10-15 parts of printing ink.

[0011] Preferably, the silicon aluminum boron crystal frit comprises the following raw materials in parts by weight:

[0012] 1-3 parts of spodumene, 2-3 parts of nepheline, 2-3 parts of aluminum ore, 2-3 parts of boric acid, 1-3 parts of strontium carbonate, 1-3 parts of albite, 2-3 parts of silicon dioxide, 1-3 parts of sodium silicate, 1-3 parts of silicon nitride, and 2-3 parts of boron nitride.

[0013] Preferably, the preparation method of the silicon-aluminum-boron crystal frit comprises the following steps: preparing the corresponding raw materials in parts by weight, mixing the raw materials, calcining them at 1250-1360°C for 1 hour, crushing them with a crusher, passing the coarse material through a 20-100 mesh sieve, ball milling them for 5-7 hours, passing them through a 300-500 mesh sieve, and then transporting them to an electric furnace for calcining for 2-4 hours to obtain the silicon-aluminum-boron crystal frit.

[0014] More preferably, the electric furnace calcination temperature is 300-400°C.

[0015] In this application, the addition of polyvinyl chloride methyl paste, printing oil and water has a suspending effect on the semi-transparent jade marble glaze layer, which is not easy to precipitate and not easy to stick to the screen, which is beneficial to the special requirements of screen printing, beneficial to the lubricity of production, beneficial to improving the performance of the glaze slurry, and convenient for glazing.

[0016] In the present application, the semi-transparent jade marble glaze layer is added with silicon-aluminum-boron crystal frit powder, lithium porcelain stone, zinc oxide, fluorite, and lithium carbonate, which are combined during the firing process to become semi-transparent jade crystals. The semi-transparent jade crystal nucleus has stable performance, the glaze is finer, the semi-transparency is stronger, the wave transmission and heat resistance are better, and multi-dimensional crystals are formed, which play a role in the adsorption of heat-resistant crystal particles on the surface, making the surface denser and the jade feeling stronger. It can be used as a reinforcement material for the marble glaze surface, and is used in the present application to improve the wave transmission and heat resistance. By adding silicon-aluminum-boron crystal frit powder and lithium carbonate, the acid and alkali resistance level is improved, and the firing time of the glaze layer can also be reduced; the transparency of the glaze is improved, and by adding fluorite and zinc oxide, the glaze layer has better anti-fouling properties.

[0017] Specifically, compared with ordinary ceramic tiles, the density of the glaze layer can be improved by adding silicon-aluminum-boron crystal frit powder into the semi-transparent jade marble glaze layer. The frit contains silicon dioxide, aluminum ore, sodium silicate, silicon nitride, and boron nitride. The semi-transparency of the glaze layer can be improved by adding lithium porcelain stone and strontium carbonate.

[0018] In this application, the melting point of the silicon aluminum boron crystal frit powder is 1180-1190°C, the heat resistance temperature reaches 1220°C, the Mohs hardness is 5, the tensile strength is greater than 6.5GPa, and the tensile elastic modulus is greater than 700GPa, showing high elasticity, good mechanical strength, stretchability, heat resistance, electrical insulation and neutron heat absorption performance.

[0019] Similarly, the present application provides a method for preparing semi-transparent screen-printed brush-polished jade-like glossy ceramic tiles, comprising the following steps:

[0020] S1. The green body is pressed using conventional ceramic green body raw materials, dried and set aside;

[0021] S2. Moisten the dried green body with water so that the green body surface contains 3-7% moisture;

[0022] S3 prepared according to the weight of each raw material of the glaze layer, the raw materials were thoroughly mixed and ball-milled, evenly applied to the body obtained in step S2, set aside;

[0023] S4 in accordance with the requirements of the 12-channel inkjet marble pattern, applied by a 12-channel inkjet machine to the surface of the glaze layer obtained in step S3 to form a marble pattern layer;

[0024] S5 prepared according to the weight of each raw material of the semi-transparent jade marble glaze layer, thoroughly mixed and then ball-milled, evenly applied to the marble pattern layer of the green body obtained in step S4, and set aside;

[0025] S6. The green body obtained in step S5 is calcined in a kiln at high temperature to obtain semi-transparent marble glaze marble tiles.

[0026] Preferably, in step S6, the high temperature calcination temperature is 1200-1220° C., and the time is 60-65 min.

[0027] Preferably, in step S3, after mixing the raw materials of the surface glaze layer, 38-42% of water by weight of the surface glaze layer is added, and the mixture is ball-milled for 8-10 minutes per 100g. The obtained surface glaze layer mixture is passed through a 325-mesh sieve and set aside.

[0028] Preferably, in step S5, after the raw materials of the semi-permeable jade marble glaze layer are mixed, 10-15% of water by weight of the semi-permeable jade marble glaze layer, 1% of an anti-sticking agent by weight of the semi-permeable jade marble glaze layer, and 0.5% of a degumming agent are added, and the mixture is ball-milled for 34 minutes per 100g. The obtained semi-permeable jade marble glaze layer mixture is passed through a 325-mesh sieve and set aside.

[0029] More preferably, the anti-sticking agent is ethylene glycol, which can solve the sticking phenomenon generated during the screen printing process.

[0030] More preferably, the disintegrator is sodium humate. When sodium humate is mixed with the glaze, the humic acid anions are adsorbed by the edges of the kaolin crystals in the ceramic mud (positive), increasing the zeta potential and double layer thickness of the clay suspension, allowing the mud to release more free water, reducing the viscosity of the suspension, improving the fluidity of the mud, and enhancing the semipermeability of the particles.

[0031] The beneficial effects of the present invention are:

[0032] 1. The present invention adds silicon-aluminum-boron crystal frit powder, corundum, lithium porcelain stone, lithium carbonate and zinc oxide to the semi-transparent jade marble glaze layer, so that zinc oxide and lithium carbonate can be better adsorbed on the surface of the green body during the firing process, thereby greatly reducing the firing time.

[0033] 2. The tiles prepared in this application have a kiln gloss of 30-40 degrees, with clearer and more transparent gloss and color, smoother glaze, more stable production, high efficiency, simpler polishing, and high production quality.

[0034] 3. The tiles prepared in this application have an anti-slip grade of R11, have a very high anti-slip function, and can achieve a good anti-slip effect. DETAILED DESCRIPTION

[0120] There is no silicon-aluminum-boron crystal frit powder in the semi-transparent jade marble glaze layer, and the other conditions are the same as those in Example 1;

[0121] Specifically, in the above embodiments and comparative examples, the thickness of the common marble tile blank and glaze is 12.07mm; the thickness of the semi-transparent jade marble glaze layer is 11.97mm: after high-temperature calcination, it is also polished. For common marble, the last polishing process after firing requires 20 sets of polishing grinding heads, while the semi-transparent jade marble glaze layer requires 30 sets of polishing grinding heads, and 10 sets of fine grinding heads. The glaze layer has a strong jade-like feel, a smoother glaze surface, a delicate feel, and a clearer visual sense of the pattern.

[0122] The marble tiles prepared in Examples 1-5 and Comparative Examples 1-2 were tested for performance, and the relevant results are summarized in Table 1 below:

[0123] Among them: the anti-fouling level is to apply oil-based markers, ink, and cement to the tile surface, let it stand for 20-30 minutes, rinse with clean water, and evaluate the residual surface marks according to relevant standards; the higher the anti-fouling level, the fewer residual marks on the tile surface and the better the surface anti-fouling effect.

[0126] As shown in Table 1 above, the marble tiles prepared in Examples 1-5 of this application had a kiln gloss of 30-40 degrees, a clearer glaze color, and a delicate feel. Their anti-slip ratings all reached R11, indicating a high anti-slip rating and a significant anti-slip effect. Furthermore, the marble tiles exhibited high hardness, excellent wear resistance, and excellent anti-fouling properties, reaching a grade of 5.

[0127] In contrast, in Comparative Example 1, marble tiles produced without the addition of a semi-transparent jade marble glaze had a gloss of approximately 35 degrees straight out of the kiln. Even after brushing and polishing, the gloss stabilized to a maximum of 27 degrees. The anti-slip rating was R10, a low level of anti-slip performance. Furthermore, the marble tiles had a stain resistance rating of only 2, and a slightly delicate feel, clearly lacking the gloss and feel of jade marble.

[0128] In contrast, in Comparative Example 2, there is no silicon-aluminum-boron crystal frit powder in the semi-transparent jade marble glaze layer, and the marble tiles prepared have a rough feel, a level 3 anti-fouling rating, a poor appearance, and no jade-like feel.

[0129] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the scope of protection of the present invention.
