Description

Technical Field

[0001] This invention relates to the field of wood grain-effect slab technology, specifically to a glaze with wood grain-effect and its application in the preparation of highly realistic wood grain-effect slabs. Background Technology

[0002] Wood products are widely used in various fields, especially the furniture industry. Wood grain patterns are widely used in furniture and architectural decoration projects due to their realistic texture and natural simplicity.

[0003] However, wood products are limited by their lack of durability, susceptibility to dirt and corrosion, making wood-grain slabs a more comprehensive option.

[0004] Existing wood-look technologies mostly involve printing and etching to add wood grain to slabs. However, the wood grain lacks the luster of wood and is not realistic. CN114315425B discloses a method for preparing a soft-light glaze with a skin-like texture for ceramic tiles. However, this method requires a protective layer, which is costly and easy to peel off from the body. Therefore, there is a need for a wood-look slab with both visual realism and good adhesion. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a glaze with a wood grain-like sheen and its application in preparing highly realistic wood grain-like slabs. The slabs possess realistic wood grain texture layers, wood luster, and good adhesion, thereby solving the problems mentioned in the background art.

[0008] Preferably, the highly realistic wood grain light-reflecting slab, wherein the modified wood grain color light-reflecting glaze comprises, by weight: 68-72 parts of base glaze, 1-2 parts of copper oxide, 2-5 parts of aluminum oxide, 10-12 parts of silicon dioxide, 1-2 parts of calcium oxide, 2-4 parts of quartz powder, 1-2 parts of pigment, and 10-14 parts of light-reflecting frit.

[0012] S2. Weigh the base glaze, copper oxide, aluminum oxide, calcium oxide, and photosensitive frit according to the raw material ratio, and put them into a ball mill jar together with mixture A. Add water and additives, and ball mill until the slurry is 300 mesh and the residue is less than 0.7%.

[0013] S3. Place the mixture from step S2 into a reaction vessel, heat it to maintain the temperature inside the reaction vessel at 50℃-60℃, slowly pour in the pigment, and stir at a speed of 50-70 rpm for 30 minutes. After cooling to room temperature, the modified wood grain color glossy glaze is obtained.

[0014] Preferably, the additives are sodium carboxymethyl cellulose and sodium tripolyphosphate; the content of sodium carboxymethyl cellulose accounts for 0.3-0.5% of the glaze mass, and the content of sodium tripolyphosphate accounts for 0.1-0.2% of the glaze mass.

[0064] Comparative Example 1.

[0065] Unlike Example 3, the photosensitive frit contains 12 parts quartz, 24 parts calcite, and 20 parts barium carbonate by weight, while the rest are the same.

[0066] Comparative Example 2.

[0067] The difference from Example 3 is that the calcination temperature for preparing the photosensitive frit is 700°C, while the rest are the same.

[0068] Comparative Example 3.

[0069] Unlike Example 3, when preparing the modified wood grain color glossy glaze, the quartz stone and silicon dioxide were not pre-calcined at high temperature, but all other aspects were the same.

[0070] Comparative Example 4 differs from Example 3 in that copper oxide and aluminum oxide are not added to the raw material components when preparing the modified wood grain color glossy glaze; all other components are the same.

[0071] To further demonstrate the effectiveness of the present invention, performance tests were conducted on the products of Examples 1-3 and Comparative Examples 1-3.

[0072] Three rock slab samples were prepared according to Examples 1-3 and Comparative Examples 1-4 respectively, and tested and evaluated. The evaluation results are shown in the table below:

[0073]

[0074] As can be seen from Examples 1-3, the slabs made according to the present invention have good wood gloss and color, and highly realistic wood grain texture. The high-temperature pyrolysis of quartz stone and silicon dioxide increases the dispersion between crystals, so that the glaze can be better embedded in the slab and is not easy to crack or peel off.

[0075] As can be seen from Comparative Example 1 and Example 3, the raw materials for preparing the photosensitive frit contain only 12 parts of quartz, 24 parts of calcite, and 20 parts of barium carbonate by weight. Although the slab has a wood-like texture, it loses the luster of wood.

[0076] As can be seen from Comparative Example 2 and Example 3, when preparing the photosensitive frit, the calcination temperature was 700℃, which was not high enough. The raw material ore did not react fully, resulting in poor gloss of the slab. It had neither wood grain imitation nor gloss and aesthetic appeal.

[0077] As can be seen from Comparative Example 3 and Example 3, when preparing the slab, if the quartz stone and silicon dioxide are not calcined at high temperature to achieve high-temperature pyrolysis, the crystals are relatively compact and dense, which is not conducive to the adhesion and integration of the modified glaze, and is prone to cracking and peeling.

[0078] As can be seen from Comparative Example 4 and Example 3, the absence of copper oxide and aluminum oxide in the preparation of the glaze results in a monotonous and dull color, and the reduction of metal reduction reaction during the firing process causes the glaze to lose some of its luster.

[0079] The innovation of this invention lies in:

[0080] This invention prepares a highly realistic wood grain photosensitive slab. The modified wood grain color photosensitive glaze is produced by calcining quartz and silicon dioxide, causing them to pyrolyze at high temperature. This improves the dispersion between crystals, allowing the slab to better integrate with the base glaze and metal oxides, increasing the color rendering effect and partial gloss of the slab, and improving adhesion. The modified wood grain color photosensitive glaze containing photosensitive frit creates a unique wood grain color and soft gloss on the glaze surface. This not only provides a good gloss effect but also makes the glaze surface texture fine, beautiful, and layered, reducing glaze peeling and significantly lowering the cost of slab deformation and glaze consumption.

[0081] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

[0082] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
