Technical Field
The invention belongs to the technical field of ceramic materials, and relates to a pearlescent ceramic material and a preparation method thereof.
Background
Glazed ceramic products are widely used in construction and home decoration as the mainstream building ceramic products at present because of excellent mechanical and decorative properties. The transparent glaze covered on the surface of the glazed ceramic product is generally a glass phase layer, and is typically characterized in that the X-ray diffraction pattern of the transparent glaze layer has no sharp diffraction peak, and only has dispersion peaks in a low diffraction angle range. Unlike the amorphous and disordered nature of the glassy phase, crystals generally have an anisotropic structure, and the internally periodic arrangement of the crystalline material imparts unique physical and chemical properties. Controlling or inducing the precipitation of crystals in a glaze of appropriate composition is one of the important directions for enhancing the physical and decorative properties of the glaze. Therefore, a pearlescent material is developed, and the effect of separating out scheelite crystals with submicron to micron size in a glaze layer and matching with a micro-die is different in color luster along with different light rays and angles, so that the product has more three-dimensional effect and stronger visual impact.

1. Wear resistance test
The ceramic materials prepared in examples 1 to 3 and comparative examples 1 to 4 were used as test pieces, and the abrasion resistance of the ceramic glaze surface was measured by the method of GB/T38107-2006, and the test results are shown in Table 1.
Table 1 results of abrasion resistance test
| Sample preparation | Wear rating |
| Example 1 | 5 |
| Example 2 | 5 |
| Example 3 | 5 |
| Comparative example 1 | 3 |
| Comparative example 2 | 3 |
| Comparative example 3 | 4 |
| Comparative example 4 | 4 |
As can be seen from Table 1, examples 1 to 3 were rated 5 in abrasion resistance, comparative examples 1 to 2 were rated 3 and comparative examples 3 to 4 were rated 4. The ground glaze reacts with albite and quartz in the overglaze to generate sodium silicate calcium salt, so that the ceramic product has better hardness and wear resistance. The deep ink enhances the adhesive force of the deep ink by adding the vitrification agent and the thickening agent, thereby enhancing the wear resistance.
2. Irradiation test
Taking the ceramic materials prepared in examples 1-3 and comparative examples 5-10 as samples, under the condition that the incandescent lamp is directly irradiated at 400W and the direct irradiation distance is 25cm, observing the observed pattern color conditions under the condition that the incandescent lamp is directly irradiated and under natural light (12-14 noon); specific observations are shown in table 2 below:
TABLE 2 irradiation test results
| Sample preparation | Filament lamp (texture pattern) | Natural light (texture pattern) |
| Example 1 | +++++ | +++++ |
| Example 2 | +++++ | +++++ |
| Example 3 | +++++ | +++++ |
| Comparative example 5 | ++++ | +++ |
| Comparative example 6 | ++++ | +++ |
| Comparative example 7 | ++++ | +++ |
| Comparative example 8 | ++++ | +++ |
| Comparative example 9 | ++++ | +++ |
| Comparative example 10 | ++++ | +++ |
Note that: "+" is clear visibility, with more clear visibility being greater and less clear visibility being vice versa.
As can be seen from the irradiation results of Table 2, the ceramic materials prepared in examples 1 to 3 were clearly visible in both incandescent lamps and natural light in texture patterns, and had a clear feel, showing a remarkable stereoscopic effect. The comparative examples 5 to 10 had slightly weaker sharpness of the texture pattern under direct irradiation of the incandescent lamp, and the three-dimensional effect was lowered. The definition of the texture pattern is weaker under natural light. Mineral dyes have different wavelengths and light has different degrees of scattering and absorption properties, and synergistically enhance to produce a wide range of colors and stereoscopic effects.
The present invention is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present invention.
