Description
Technical Field
The invention relates to the technical field of ceramics, in particular to a velvet ceramic rock plate and a preparation method thereof.
Background
With the development of economy and the improvement of the living standard of people, the building ground decoration industry is more and more emphasized, and occupies a main part in home decoration. The floor decoration materials in the market are more, the three types of floor materials widely applied at present are wood floors, stone materials and ceramic tiles, from the aspects of economy, practicability, decoration and the like, the ceramic tiles are popular with consumers due to the characteristics of beauty, simplicity, easy cleaning and the like, and the ceramic tiles are increasingly used in large buildings such as exhibition halls, hotels, supermarkets, shopping centers, restaurants, gymnasiums, swimming pools, bathrooms and civil houses. Therefore, people have higher requirements on the decoration, environmental protection, durability, surface appearance, use comfort, skid resistance, wear resistance and antifouling effect of the material. However, the existing ceramic tile has single function and cannot meet the requirements of people in various aspects.
At present, the common methods for preparing ceramics in the market comprise full polishing, soft polishing, candy glaze, fine and matte and the like, but the perfect effect cannot be achieved. (1) The full-polishing method is adopted, the brightness is high, about 80-90 degrees, the texture is transparent, the texture definition is relatively common, the fuzzy feeling that ink is slightly separated from points and lines can be seen by fine observation, and the decorative effect is influenced because the reflective surface has water ripples. (2) Softening light: the brightness is about 15-30 degrees, and there are two processes for making soft light on the market, one is that the surface brightness of the common antique glaze is adjusted through a polishing procedure, and the problem that antifouling materials or glaze pores cannot be added in the polishing procedure, so that the poor antifouling property of the soft light product is a pain point which is difficult to solve all the time; the other is soft glaze (such as satin glaze), which has slightly improved antifouling property compared with the former process, but can not avoid the hiding of surface pores and the skid resistance. Therefore, the current industrial soft light process has the problems of insufficient antifouling property and skid resistance. (3) Candy glaze: the glaze surface has dispersive flash effect, flaky light reflection has bright effect, visual fatigue is easy to cause after long time, and slight gully is formed among the candy particles on the surface, so the candy particles are easy to store and dirty and have poor antifouling property. (4) Fine and dumb: the brightness is 15-20 degrees, the paint is finer and smoother than soft light, the antifouling performance is poor, and obvious scratches are formed in metal scraping and cannot be removed.
In conclusion, the existing ceramics have the problems of uncomfortable brightness, unclear texture, poor wear resistance, visual fatigue caused by reflected light, insanitation and the like. The rock plate is applied to products in different fields as a novel decorative material, has the properties of hard texture, scratch resistance, corrosion resistance, lightness, thinness, safety, sanitation, environmental protection, fire resistance, high temperature resistance, high compactness, strong pollution resistance, easy cleaning and the like, and can be directly contacted with food. The application of rock plates to the ceramic field is imperative.
Therefore, it is highly desirable to provide a velvet ceramic rock plate with hardness, wear resistance, moderate brightness, clear texture and other functions and a preparation method thereof.
