Description

Technical Field

[0001] The invention relates to the field of soft-light ceramic tile processing, and in particular to a wear-resistant soft-light tile with a translucent texture and a preparation method thereof. Background Art

[0002] For a long time in the past, the "super-bright" ceramic tiles in the building ceramics industry have been favored by many consumers due to their super-high surface gloss, high hardness and good anti-fouling performance. However, super-bright ceramic tiles have a high reflectivity to light, which is easy to cause light pollution and visual fatigue. Therefore, with the continuous improvement of people's living standards, higher requirements are placed on the gloss of ceramic plates. In recent years, the market share of soft-light ceramic tiles with lower gloss has increased rapidly. The gloss of soft-light ceramic tiles is usually controlled at 20°-55°, so that the light is scattered rather than reflected by a mirror, effectively avoiding dazzling light spots and glare problems, and is especially suitable for the pursuit of soft light in modern homes.

[0003] There are three main ways to obtain soft light effect on the surface of existing soft light ceramic tiles: One is to softly polish the glaze surface of the ceramic tile to a soft light to achieve a soft light effect. The polishing tools of this soft light process rub the glaze surface unevenly, leaving marks of the grinding head on the tile surface and destroying the crystal structure of the glaze. There will be tiny pores on the surface, which are easy to hide dirt and grime, and its anti-fouling performance is poor.

[0004] The second method is to apply a layer of specially adjusted soft-light glaze on the surface of the ceramic tile and adjust the glaze formula to reduce the glossiness of the glaze surface; however, the glaze research and development cost of this soft-light method is high.

[0005] Third, a layer of silicone oil-based soft light anti-fouling liquid is applied on the surface of the ceramic tile to form a transparent crystalline film on the tile surface, increase the height and maintain the soft light effect; for example, patent CN202310461306.6 discloses a kind of anti-fouling soft light ceramic tile and its preparation method, which is specifically applied on the brick blank with a thin concentration and large particle size of nano-silica sol so that it adheres to the surface of the rough brick blank, which can be adapted to fill and repair the coarse holes and cracks of the rough brick blank. Then, on the repaired rough brick blank, apply wear-resistant soft light anti-fouling liquid for polishing, glazing and anti-fouling, which can form a transparent crystalline film on the brick surface, increase the height and maintain the soft light effect, and has excellent anti-fouling effect.

[0006] However, the soft light ceramic tile prepared by the above method has obvious antifouling effect, but its cured film is soft in texture, and its wear resistance and weather resistance are not durable enough.

[0007] Therefore, it is urgent to develop an iterative method such as the patent CN202310461306.6 which discloses an anti-fouling soft-light ceramic tile, which has a soft light sensation and anti-fouling effect, while improving the surface wear resistance and weather resistance of the ceramic product, thereby increasing product shipments and market recognition.

After the marks are fully dry, wash them with detergent and water to observe whether they are clean. It is divided into multiple grades according to the degree of cleanliness.

[0062] The test of the translucent texture and long-lasting wear resistance of the soft light ceramic tile surface refers to repeatedly rubbing the bottom surface of the ceramic tile prepared in each embodiment with a brush within a specified time, rubbing 10 times a day, each time for 10 minutes, for a total of 28 days to simulate the scene of repeated stepping on by shoes after the tiles are laid, and finally observing the translucent texture of the tile surface.

[0063] Table 2 is the performance test results of the soft light ceramic tiles of Examples 1-4 and Comparative Examples 1-9 Glossiness Antifouling ability The transparent texture of the tile surface is durable and wear-resistant Example 1 38 excellent After 28 days of testing, the brick surface is translucent and durable. Example 2 42 Optimal After 28 days of testing, the brick surface is translucent and durable. Example 3 35 excellent After 28 days of testing, the brick surface is translucent and durable. Example 4 41 Optimal After 28 days of testing, the brick surface is translucent and durable. Comparative Example 1 40 Optimal The transparency and texture of the tile surface will decrease after about 3 days. Comparative Example 2 38 Difference The tiles began to lose their brightness and texture around the 21st. Comparative Example 3 33 Difference The transparency and texture of the tiles will decrease around the 6th day. Comparative Example 4 35 Difference The transparency and texture of the tile surface will decrease around 10 days. Comparative Example 5 32 Difference The transparency and texture of the tiles will decrease around the 12th day. Comparative Example 6 37 Difference The transparency and texture of the tile surface will decrease around the 4th day. Comparative Example 7 38 good The glossiness of the tiles will decrease after about 4 days. Comparative Example 8 46 excellent The glossiness of the tile surface decreases after about 5 days. Comparative Example 9 40 excellent The glossiness of the tiles will decrease after about 4 days. It can be seen from the above table that compared with the existing soft light ceramic tile products of comparative examples 8-9, the soft light tiles of embodiments 1-4 can achieve excellent results in glossiness, anti-fouling ability, and long-lasting and wear-resistant effects of translucent texture, especially embodiment 2, which has high durability of translucent texture and is wear-resistant without loss, and is the optimal implementation method.

[0064] Compared with Example 2, the silicone oil material used in Comparative Example 1 is cured into a soft light film. Although the anti-fouling effect is obvious, the cured film is soft in texture and has insufficient wear resistance and weather resistance.

[0065] Compared with Example 2, in step (1), the comparative example 2 lacks a preheating process, which makes it impossible to open the pores of the rough brick blank, and the microscopic pores are not fully filled, which seriously affects the absorption and curing of the subsequent wear-resistant soft light material, resulting in poor anti-fouling properties of the tile.

[0066] Compared with Example 2, in the wear-resistant softening liquid formula of step (2), the comparative example 3 lacks boronized emulsion, and the filler crystal density is insufficient, which reduces the hardness and wear resistance of the crystal layer, deteriorates the brightness and anti-fouling performance, and the crystal film has a short lasting and transparent time.

[0067] Compared with Example 2, in the formulation of the wear-resistant softening liquid in step (2) of Comparative Examples 4-5, excessive or small amounts of boron carbide or cubic boron nitride cannot form a durable and transparent crystalline film on the brick surface, which reduces the glossiness and transparency durability of the brick surface to a certain extent.

[0068] Compared with Example 2, in Comparative Example 6, in step (2), boron carbide is directly added to the wear-resistant soft light liquid without pre-emulsification treatment, which will affect the stability of the boron emulsion system and form precipitation. The stability of the formed crystalline film is not high, and the transparency of the crystalline film is maintained for a short time.

[0069] Compared with Example 2, Comparative Example 7 lacks the soft light curing step in step (3), and the formed crystalline film has a poor curing effect and its transparency is maintained for a short time.

[0070] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
