Velvet ceramic rock plate and preparation method thereof

Abstract

The invention discloses a velvet ceramic rock plate and a preparation method thereof. The velvet ceramic rock plate sequentially comprises a green body layer, a velvet texture layer and a three-dimensional flashing layer from inside to outside, wherein the velvet texture layer comprises a velvet glaze; the three-dimensional glittering layer comprises a three-dimensional glittering glaze, and the three-dimensional glittering glaze is formed by mixing glittering particles and the velvet glaze; and the velvet glaze is mainly prepared from the following raw materials: potassium carbonate, quartz,calcite, feldspar, boric acid, talc, zircon sand and nano-powder of metal oxides. According to the velvet ceramic rock plate, nano-powder of metal oxides such as Al2O3, TiO2, CaO and ZrO2 is added andsprayed on the rock surface to form a protective layer, so the velvet ceramic rock plate is hard in texture, resistant to scratches, corrosion, high temperature and fire, light and thin; and added nano-zinc oxide, nano-magnesium and nano-calcium oxide have antibacterial property and can make direct contact with food.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a velvet ceramic rock plate and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, more and more attention has been paid to the building floor decoration industry, which occupies a major part in home decoration. There are many floor decoration materials on the market. At present, the three types of floor materials widely used are wooden floor, stone and ceramic tile. From the aspects of economy, practicality and decoration, ceramic tile is characterized by its beauty, simplicity and easy cleaning. It is loved by the majority of consumers, and it is used more and more in large buildings such as exhibition halls, hotels, supermarkets, shopping centers, restaurants, gymnasiums, swimming pools, bathrooms and residential buildings. As a result, people have higher requirements for the decor...

AI Technical Summary

Problems solved by technology

However, the current ceramic tiles have a single function and cannot meet people's various requirements at the same time.

[0003] At present, the commonly used methods for preparing ceramics on the market include full polishing, soft light, candy glaze, fine matte, etc., but none of them can achieve perfect results.

(1) The method of full polishing is adopted, the brightness is high, about 80°-90°, the texture is transparent, and the texture definition is relatively average. If you look closely, you can see that the points and lines have a fuzzy feeling of ink slightly melting, and the reflective surface There are water ripples, which affect the decorative effect

(2) Soft light: the brightness is about 15°-30°. There are two kinds of soft light processes on the market. One is to adjust the surface brightness of ordinary antique glaze through the polishing process. Due to the polishing process, anti-fouling materials or glazes cannot be added. The problem of porosity, resulting in poor anti-fouling of soft light products has always been a difficult pain point to solve; the other is to use soft light glazes (such as satin glaze), the anti-fouling performance is slightly improved compared with the previous process, but it is also avoided No dirt storage and anti-slip properties of surface pores

Therefore, the current soft light process in the whole industry has the problem of insufficient anti-fouling and anti-slip properties.

(3) Candy glaze: The glaze surface presents a dispersed flash effect, and the light reflection of the pieces presents a bright effect, which is easy to cause visual fatigue for a long time, and there are slight gullies between the candy particles on the surface, which are easy to hide dirt and have poor antifouling ability

[0004] In summary, the current ceramics have problems such as uncomfortable brightness, unclear texture, poor wear resistance, visual fatigue caused by reflected light, and unhygienic.
