Description

Technical Field

[0001] The invention relates to the technical field of ceramic tile glazes, and in particular to a glaze with a marble-like light feeling and application of the glaze in preparing ceramic tiles with a high-fidelity marble-like light feeling. Background Art

[0002] The glaze applied to imitation marble tiles is generally made of natural ore. After grinding and adding water, it is applied to the surface of the body and melted by roasting at a certain temperature. When the temperature drops, a thin glass layer is formed on the surface of the ceramic. It increases the mechanical strength, thermal stability, and dielectric strength of the ceramic and prevents erosion by liquids and gases. It also increases the beauty of the tiles, makes them easy to clean, and prevents them from being stained by dust.

[0003] The natural minerals used in existing marble-like glazes are non-renewable resources. Long-term and large-scale mining is not conducive to long-term development. Moreover, the glazes either have a rough surface with low gloss or a smooth surface with high gloss. The two cannot be taken into account at the same time. There are also marble-like glazes with good light perception. On the basis of the original ordinary matte glaze, they add soft polishing equipment to softly polish the glaze. Although this soft polishing has low gloss, it greatly increases the production cost. There is also a soft glaze that sprays low-gloss ink on the high-gloss glaze. Although this process is simple to operate, the light perception of the tile surface is uneven. Summary of the invention

[0107] Comparative Example 1.

[0108] The difference from Example 3 is that the kaolin is not modified.

[0109] Comparative Example 2.

[0111] Comparative Example 3.

[0112] The difference from Example 3 is that excess amounts of barium oxide and manganese oxide are added to the composite matte material.

[0113] The products of Examples 1-3 and Comparative Examples 1-3 were subjected to performance tests;

[0114] 30 glaze samples were prepared and divided into 6 groups with 5 samples in each group. Each group corresponded to Examples 1-3 and Comparative Examples 1-3 and were numbered A / B / C / D / E / F. The glazes were applied on the surface of ceramic tiles. After high-temperature firing, the glaze samples of groups A / B / C / D / E / F were tested respectively. The test results are shown in the following table.

[0115]

[0116] It can be seen from Examples 1-3 that the glaze with imitation marble luster made by the present invention and its application in the preparation of ceramic tiles with high-fidelity imitation marble luster is prepared by mixing natural minerals with modified kaolin and composite matte materials. The glaze prepared under a specific ratio improves the glossiness of the glaze surface, achieving the purpose of smooth and delicate glaze surface with low glossiness.

[0117] It can be seen from Comparative Example 1 and Example 3 that the dispersibility of the kaolin in the glaze is improved after being modified with stearic acid and octadecyltrimethylammonium bromide, thereby enhancing the connection strength between the glaze components and improving the hardness of the glaze;

[0118] In addition, it was found from Comparative Examples 2-3 that in the preparation of glazes with imitation marble luster and their use in the preparation of ceramic tiles with highly realistic imitation marble luster, the excessive addition of barium oxide and manganese oxide in the composite matte material reduced the transparency of the glaze, distorted the texture of the glaze surface, and the glossiness of the glaze was higher.

[0119] The innovation of the present invention is:

[0120] The present invention uses natural minerals as a matrix, and mixes them with modified kaolin and a composite matte material to prepare a glaze prepared under a specific ratio, which improves the glossiness of the glaze surface, achieves the purpose of a smooth and delicate glaze surface with low glossiness, and ensures good wear resistance and light perception. At the same time, the dispersibility of the kaolin in the glaze is improved after being modified with stearic acid and octadecyltrimethylammonium bromide, thereby enhancing the connection strength between the glaze components, so that the hardness of the prepared tile with imitation marble light perception is better.

[0121] 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 present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0122] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
