Description

Technical Field

[0001] The present invention belongs to the technical field of building ceramics, and in particular relates to a point-transmitting ceramic rock plate with a relief effect and a manufacturing method thereof. Background Art

[0002] In recent years, with the continuous advancement of science and technology, the production technology of building ceramics has developed rapidly, various new processes and new formulas have been continuously applied, product development tends to be diversified, fashionable, environmentally friendly and healthy, and the decorative effects tend to be refined and personalized.

[0003] As a way of exporting Chinese culture throughout history, ceramics have integrated cultural elements into modern design to achieve cultural inheritance and continuation. For example, the design of products such as gold inlaid jade, wood inlaid jade, and stone inlaid jade not only integrates traditional craftsmanship with modern aesthetics, embodies the perfect combination of tradition and modernity, but also inherits and promotes local culture, becoming an important carrier for cultural dissemination.

[0004] CN101898891A discloses a semi-transparent ceramic material, a ceramic thin plate and a preparation method thereof. The method adopts a method of mixing multiple micro-powders, and the semi-transparent ceramic material is passed through a carved roller and a belt to make the fabric freely fall onto a base material, and then is flattened with a rubber roller to realize staggered translucent areas and opaque areas, and achieve an effect of staggered translucent and opaque areas under light. This method of achieving the effect of staggered translucent and opaque areas by staggered spreading of the materials, on the one hand, will keep the large pattern unchanged when spreading, and can only make some small position changes locally, and cannot achieve random positioning matching of the surface decorative pattern and the translucent position. On the other hand, the semi-transparent ceramic material and the base material are two different powders, which are difficult to be compatible when combined. The mismatch of the two powders will lead to uneven strength of the green body, and the uniformity of the green body strength cannot be controlled. The green body is prone to breakage and cracking during the production process, and the brick is also prone to cracking during the firing process.

[0005] CN110845227A discloses a translucent ceramic tile with positioned crystal flowers and a preparation method thereof, wherein a pattern is inkjet printed on a translucent blank, and then dry particles of a crystal nucleating agent are applied, and a crystal flower dry particle glaze is applied on the surface. Although this process can display the unique artistic beauty of the positioned crystal flowers, the pattern will be blurred when inkjet printing is performed on the blank, and the subsequent application of the crystal flower dry particles will further affect the color and transparency of the product. The overall decorative effect of the product is fuzzy and cannot achieve the transparency of jade.

[0006] The dramatic multi-color translucent three-dimensional effect ceramic rock slab and its manufacturing method disclosed in CN113896569A mainly prepare a variety of color translucent formulas for distribution, so as to achieve a three-dimensional texture effect from the surface to the bottom of the multi-color translucent blank. However, it is a fully transparent type and cannot achieve a fixed-point translucent effect. Summary of the Invention

[0037] Another technical solution of the present invention is the ceramic rock plate with a relief effect and fixed-point light transmission, which is special in that it is prepared by the preparation method of the ceramic rock plate with a relief effect and fixed-point light transmission as described in any one of claims 1 to 9 and 13.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] (1) Glass frit is added to the jade-like semi-opaque green body formula of the present invention. Taking advantage of the characteristics of glass frit with a low melting temperature and a wide sintering temperature range, it can not only improve the whiteness of the ceramic green body, but also form potassium barite and calcium feldspar with the barium-based frit at a lower temperature, thereby increasing the light transmittance of the green body.

[0040] (2) Barium-based frit is added to the jade-like semi-opaque green body formula of the present invention. During the firing process, the barium-based frit forms barium cryolite with a refractive index close to that of the glass phase, which reduces the glass phase in the green body while increasing the crystal phase content in the green body, which is beneficial to improving the high-temperature sintering performance of the ceramic green body, reducing the loss of light in the ceramic green body, and improving the light transmittance of the green body. It solves the problem that traditional translucent bricks add barium carbonate raw materials to improve the light transmittance, and then introduce carbon elements, causing the green body to burn out too many components, resulting in a black core in the green body.

[0041] ⑶ The water-retaining zirconium-based ultra-white cosmetic clay of the present invention is prepared using jade-like semi-emulsified green body powder as the basic raw material. The green body and glaze have better matching properties and high whiteness, which is conducive to the coloring of inkjet inks. It can prevent the bonding ink printed in the next process from quickly penetrating into the green body, which is conducive to the subsequent adhesion of granular powder and ensures the bonding process effect of the subsequent process.

[0042] (4) The organic material in the bonding ink of the present invention is zirconium oxide. Under high-temperature firing conditions, zirconium oxide can deeply react with the matte opacifying particle powder to form a zirconium-based glaze layer with obvious opacifying effect.

[0043] (5) The matte opacifying granular powder of the present invention is made by a lightly calcined process, and its particles tend to be spherical. Compared with traditional frit dry particles, the powder made by the lightly calcined process has better fluidity.

[0044] (6) The matte opacifying granular powder of the present invention has a high initial melting point and good reactivity, and can easily react with the zirconium oxide in the bonding ink under high-temperature firing conditions to generate a zirconium-based glaze layer with obvious opacifying effect. That is, the product has an opacifying glaze layer after firing at the position where the matte granular powder is adhered. The bonding ink design file can be adjusted according to the product development and design requirements, and the layout of the bonding ink quantity can be controlled by the file. The position where there is no bonding ink will not be adhered to the matte opacifying granular powder. When the thickness of the blank is 9 mm, the visible light transmittance of the blank + glaze layer at this position after firing is 5.5%. The bonded matte opacifying granular powder at the position where the grayscale of the bonding ink printing file is 100% is ≥500g / m 2 The visible light transmittance of the body + glaze layer at this position is 0, thereby achieving a special artistic effect of jade-like translucency and shading effect. When jade-like files are used at the translucent effect position, unique effects such as inlaid jade can be formed after firing. DETAILED DESCRIPTION
