Description

Technical Field

[0001] The present invention relates to the technical field of ceramic materials, and in particular to a drop-resistant ceramic material, a preparation method and an application thereof in ceramic ornaments. Background Art

[0002] Ceramic materials, thanks to their beautiful appearance, excellent chemical stability, and unique artistic value, are widely used in architectural decoration, art ornaments, and daily utensils. This problem is particularly prominent in the field of ceramic ornaments. As decorative artworks, ceramic ornaments are inevitably subject to the risk of collision or falling during daily use, transportation, or display. Once damaged, not only does it affect its aesthetics and integrity, but it also reduces its artistic value and collectible value.

[0003] Existing ceramic materials have poor drop resistance. In order to optimize the drop resistance of the product, it is necessary to fundamentally improve the toughness and strength of the product to achieve the drop resistance effect. However, it is difficult to coordinate and balance the improvement of the strength and toughness of the product, and it is also difficult to coordinate and optimize the anti-slip performance of the product with the strength and toughness. At the same time, the product has poor sun resistance and water resistance, which limits the product's use efficiency. Summary of the Invention

[0132] The products of Examples 1 to 3 and Comparative Examples 1 to 8 were tested for anti-slip properties, strength, and toughness under normal conditions, sunlight resistance, and water resistance. The sunlight resistance and water resistance conditions were as follows: the products were exposed to the sun for 10 days in July and then immersed in water for 10 days. The test results are shown in Table 1.

[0133] Table 1 Product performance test results of Examples 1 to 3 and Comparative Examples 1 to 8:

[0134]

[0135] From Comparative Examples 1-8 and Examples 1-3, it can be seen that the product of Example 3 has excellent anti-slip properties, as well as excellent impact strength and fracture toughness. The product can achieve excellent drop resistance and anti-slip properties. In addition, the product has excellent stability under sunlight and water resistance conditions.

[0136] The present invention does not add either the zirconium oxide agent doped with aluminum silicate fiber or the boron nitride additive, and the performance of the product deteriorates significantly. The performance effect is most significant when the two additives are blended and coordinated.

[0140] Experimental Example 1:

[0141] The same as Example 3, the only difference is that sodium silicate and mica powder are not added in the preparation of the modified liquid.

[0142] Experimental Example 2:

[0143] The same as Example 3, except that silicon nitride nanowhiskers are not added to the modified liquid.

[0144] Experimental Example 3:

[0145] The same as Example 3, except that spodumene is not added to the modified liquid.

[0146] Experimental Example 4:

[0147] The same as Example 3, the only difference is that the lanthanum chloride solution in the added modifying liquid is replaced by water.

[0148] The performance tests of Experimental Examples 1 to 4 were also carried out, and the test results are shown in Table 2.

[0149] Table 2 Product performance test results of Experimental Examples 1 to 4:

[0150]

[0151] It can be seen from Experimental Examples 1 to 4 that sodium silicate and mica powder were not added in the preparation of the additive modification liquid, and the performance of the product deteriorated significantly under the conditions of sunlight resistance and water resistance. At the same time, silicon nitride nanowhiskers were not added to the additive modification liquid, and the performance of the product also changed significantly. No spodumene was added to the additive modification liquid, and the lanthanum chloride solution was replaced by water. The performance of the product also showed a trend of deterioration to varying degrees. Only the additive modification liquid prepared by the method of the present invention had the most significant performance effect of the product. The effects of using other methods were not as significant as those of the present invention. In the preparation of the additive modification liquid of the present invention, the components are unique, and the effects of using other methods were not as significant as those of the present invention.
