Waxy dry granular glaze, wax stone ceramic tile and preparation method thereof

Abstract

This invention provides a waxy dry granule glaze, wax stone ceramic tiles, and their preparation method, specifically relating to the field of ceramic technology. The waxy dry granule glaze provided by this invention, prepared using high-alumina raw materials, exhibits a wear-resistant surface after high-temperature firing, closely resembling the texture of stone, and has a smoother overall feel. This prevents scratches and abrasions on the tile surface, thus avoiding the loss of the stone-like appearance. The introduction of a certain amount of ZnO into the raw materials enhances the color development ability of the tile glaze, resulting in a more stable color effect and good glaze transparency. The wax stone ceramic tiles provided by this invention contain a waxy glaze layer, giving the tile glaze a low gloss and strong color development ability. The tile glaze has a matte finish and is wear-resistant, scratch-resistant, and abrasion-resistant, preventing surface roughness and dirt residue buildup, and facilitating subsequent polishing to create high-gloss products.

Description

Technical Field

[0001] This invention relates to the field of ceramic technology, and in particular to a waxy dry granule glaze, a wax stone ceramic tile, and a method for preparing the same. Background Technology

[0002] Traditional glazed tiles, limited by the types of glaze formulas, are typically classified into two types based on gloss level: glossy and matte. For the functional use of ceramic tiles, the visual effect of gloss is one of the important aspects of their decorative art and functionality. The potential for post-processing of ceramic tiles can give a single tile multiple facets, and a single material multiple gloss levels and textures, offering a range of decorative expressions. This will be a future direction for the development of decorative art in ceramic tile products.

[0003] Existing matte glazed tiles made of wax stone have poor color rendering capabilities, failing to replicate the texture and appearance of natural stone, resulting in unsatisfactory stone imitations. To achieve a realistic, substantial feel reminiscent of natural stone, most matte glazed tiles made of wax stone are matte products. Producing glossy glazed tiles of the same type requires a different formula and firing process, which cannot be achieved through the processing of matte products. Furthermore, matte glazed tiles made of wax stone have poor wear resistance, are easily scratched, and are unsuitable for post-processing, making it impossible to achieve a multi-faceted decorative effect with varying gloss levels and surface textures.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0118] Test Example 1

[0119] The ceramic tiles obtained in Examples 1-8 and Comparative Examples 1-5 were subjected to performance tests, specifically including: gloss, stain resistance, thermal stability, abrasion resistance in revolutions, and flexural strength.

[0120] The gloss test was conducted in accordance with the provisions of GB / T3810.14-2016.

[0121] The antifouling performance test shall be conducted in accordance with the provisions of GB / T3810.14-2016.

[0122] Thermal stability shall be tested in accordance with the provisions of GB / T3810.9-2016.

[0123] The wear resistance rotation speed shall be determined in accordance with the provisions of GB / T3810.7-2016.

[0124] The flexural strength shall be tested in accordance with the provisions of GB / 3810.4-2016.

[0125] The results are shown in Table 1.

[0126] Table 1

[0127]

[0128]

[0129] As shown in Table 1, the low firing temperature in Example 4 resulted in a significant decrease in flexural strength and the appearance of minor cracks on the brick surface. In Examples 5 and 7, the high application amount of the waxy dry granule glaze led to varying degrees of incomplete firing, affecting wear resistance. In Example 6, the low application amount of the base glaze reduced flexural strength. In Comparative Example 1, the low Al2O3 content in the waxy dry granule glaze resulted in no cracks on the brick surface, but significantly poor wear resistance because the excessively high firing temperature easily caused the glaze to burn through to its melting point. In Comparative Example 2, the high Al2O3 content in the waxy dry granule glaze increased the melting point of alumina, making it difficult to reach a suitable melting point, resulting in a duller glaze and incomplete firing. The wax stone tiles obtained in Comparative Examples 3 and 4 had an overall dark, bluish-green color; furthermore, the color of the wax stone tile obtained in Comparative Example 4 was unstable, exhibiting different appearance colors depending on the firing batch. In Comparative Example 5, the high zinc oxide content affected the wear resistance of the glaze surface.

[0130] Figure 2 and Figure 3 The images shown are photographs of the matte wax stone tile provided in Example 1 and the high-gloss wax stone tile provided in Example 1, respectively. The photographs were taken by the same researcher at the same time under the same laboratory conditions. It can be seen that... Figure 3 The highlights reflect the laboratory environment and the photographer, exhibiting good gloss; however, Figure 2 The matte finish cannot reflect the external environment.

[0131] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
