Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of ceramic tile production, and particularly relates to a multi-color sparkling effect gorgeous stone ceramic tile and a preparation method thereof. BACKGROUND

[0002] With the popularization of inkjet printing technology and the development of ceramic tile production process technology, the pattern texture of ceramic tiles produced by different manufacturers is becoming less and less different, and ordinary products are increasingly competing with each other. As a kind of home decoration material, the decorative effect and visual impact of ceramic tiles are the most intuitive. Although the patterns of ordinary glaze products are changing, the pattern levels are formed by two-dimensional plane layers through inkjet printing technology, which cannot achieve a three-dimensional effect.

[0057] The second application object of the present application is:

[0058] A multi-color flash crystal effect's rose stone ceramic tile is provided, which is prepared according to the preparation method of the multi-color flash crystal effect's rose stone ceramic tile described above.

[0059] The present application focuses on the research of the following key technologies:

[0060] (I) Preparation of transparent dry particles:

[0061] The formula composition of the transparent dry granule directly affects the transparency, stain resistance, wear resistance and other performance indicators of the product glaze. For the transparent dry granule of the gorgeous stone ceramic tile with colorful sparkling effect, in addition to meeting the basic performance of good transparency, stable color development and high wear resistance, it also needs to meet the melting temperature and expansion coefficient compatible with the crystal flash dry granule and the color mixed dry granule.

[0062] In order to obtain the transparent dry granule meeting the production needs, the present application adjusts and optimizes it from the following aspects on the basis of the existing transparent dry granule formula.

[0063] (1) Adding more potassium feldspar:

[0064] Potassium feldspar and sodium feldspar are both low-temperature fluxes commonly used in ceramic production. Compared with sodium feldspar, the initial melting point of potassium feldspar is higher, which is beneficial to the discharge of gas in the body, and the firing range of potassium feldspar is also wider than that of sodium feldspar, with a melting point of about 1130-1450℃. After melting, the glass-forming process is relatively slow, and the crystallization ability is small, which can prevent the reaction between the transparent dry granule and the color dry granule. In addition, the expansion coefficient of potassium feldspar is also smaller than that of sodium feldspar, which is more compatible with the crystal flash dry granule.

[0065] (2) Introducing corundum powder to enhance the wear resistance of the transparent dry granule:

[0066] The Mohs hardness of corundum (Al2O3) is 9. The introduced part of corundum powder does not melt at high temperature, and is uniformly distributed in the transparent dry granule in the form of residual corundum microcrystals, which can significantly improve the wear resistance of the product while ensuring sufficient transparency of the transparent dry granule.

[0067] (3) Introducing zinc oxide and barium carbonate to enhance color development:

[0068] Among the alkaline earth metal elements, barium has the largest atomic number, the largest ionic radius and the strongest basicity. Due to the larger ionic radius of barium, its fluxing range is wider. Generally speaking, from 900℃, barium oxide can play a fluxing role. Ba 2+ is in the octahedral coordination [BaO6] state, which is a typical network exoskeleton; therefore, in the frit glaze, the introduction of BaO can improve the refractive index, density, oxidation resistance and other properties of the frit glaze, and BaO has strong color development ability. Therefore, the content of barium carbonate in the transparent dry granule formula is appropriately increased.

[0069] (4) Increasing the frit firing temperature to increase the transparency:

[0070] Because more corundum micro powder is added in the transparent dry grain formula to enhance its wear resistance, the addition of corundum micro powder increases the melting temperature of the transparent dry grain, in order to increase the transparency of the transparent dry grain, the transparent clinker is fired at a temperature of 1700 DEG C in the present application. After high-temperature firing and water quenching, the transparent dry grain has stronger transparency.

[0071] (II) Preparation of the opaque dry grain:

[0072] In order to further enrich the decorative effect, the present application adjusts the color of the clinker by adding colorants. With natural stone and jade as the raw material, the present application uses two kinds of dry grains, the transparent dry grain and the opaque dry grain, as the base material for color adjustment. The transparent single-color dry grain uses high-transparency transparent dry grain as the base material, and adds green, brown yellow and the like, so that the color is more transparent and the jade texture is stronger. The opaque single-color dry grain uses semi-transparent opaque dry grain formula or semi-transparent opaque dry grain as the base material, and adds red, yellow, blue, black, green or mixed colors made by three primary colors.

[0073] The opaque dry grain has poor light transmittance, and forms a light transmittance effect contrast with the transparent dry grain, so that the boundary effect is obvious and the stereoscopic sense is stronger, like a colorful gem.

[0074] In order to obtain the opaque dry grain that meets the production needs, the present application adjusts and optimizes the existing dry grain formula from the following aspects:

[0075] (1) Introducing zirconium silicate:

[0076] Zirconium silicate forms zirconite and the like during the clinker firing process, and scatters the incident light waves, thereby achieving the effect of opacification and whitening. By adding zirconium silicate powder, the light transmittance of the opaque dry grain clinker is made worse, forming a semi-transparent or non-transparent dry grain, which forms a light transmittance effect contrast with the transparent dry grain, thereby achieving the effect of increasing the boundary effect and enhancing the stereoscopic sense.

[0077] (2) Introducing alumina powder:

[0078] Alumina (Al2O3) in the glaze forms a network intermediate, has a high melting point and stable chemical properties, and by introducing alumina, the dry grain melting range is expanded and the high-temperature stability of the opaque dry grain is enhanced. At the same time, the increase of the Al2O3 content in the opaque dry grain formula can effectively avoid the formation of pores and other defects in the preparation of the opaque dry grain. In addition, increasing the Al2O3 content in the formula can significantly increase the melting temperature of the opaque dry grain, so that there is a temperature difference between the opaque dry grain and the transparent dry grain, thereby further increasing the boundary effect and enhancing the stereoscopic level.

[0079] (III) Optimization of the dry grain process:

[0080] At present, the dry granule construction technology mainly includes wet granule construction technology, silk screen printing and dry granule construction technology. Among them, 1) the wet granule construction technology mainly mixes the dry granule and the suspending agent to prepare dry granule glaze slurry, and then applies the dry granule glaze slurry on the brick body surface through bell cover spraying. In the production process, the dry granule is easy to precipitate due to its large fineness (100-200 meshes), and the dry granule glaze slurry contains a large amount of water, which is absorbed by the body and affects the strength of the dry body, resulting in production problems such as cracked bricks. 2) The silk screen printing has a high requirement on the strength of the body, and is generally applied to the secondary firing process. The dry granule construction technology of the present application is to apply the dry granule on the brick body surface through a dry granule applicator, and then to bond and fix the dry granule by spraying glue. Compared with the wet granule construction technology, the dry granule construction technology has more stable dry granule feeding amount, less water, and is more suitable for the production of thick glaze layer, thin plate and large plate.

[0081] The present application can also position and apply the crystal flash dry granule and the color mixed dry granule by inkjet printing glue. The position of the glue corresponds to the crystal flash dry granule and the color mixed dry granule according to the design pattern, and the design pattern is processed to achieve the purpose of accurate printing. Preferably, the amount of glue is 20-90 g / m 2 , which can be adjusted according to the production plate situation. Then the crystal flash dry granule is applied by a digital dry granule machine. Preferably, the application amount of the crystal flash dry granule is 200-800 g / m 2 . The excess dry granule is removed by an air extractor to realize the effect of decorating only the color part corresponding to the design pattern. Finally, the color mixed dry granule is applied on the surface by the dry granule construction technology. The application amount of the color mixed dry granule is 1500-2800 g / m 2 . Due to the difference in temperature, color and form between the color mixed dry granule and the transparent dry granule, an obvious boundary is formed, so that the product presents a multi-color color relief three-dimensional decoration effect.

[0139]

[0140] The color dry particles in the above table refer to the mixture of transparent monochrome dry particles and opalescent monochrome dry particles in the present application.
