Problems solved by technology
However, in the production process of ceramic wall and floor tiles, the technical process of green body→applying make-up soil / underglaze→printing→applying transparent glaze / protective glaze is usually adopted. A layer of white glaze layer, the thickness is generally 0.2 ~ 0.4mm, after water jet cutting, chamfering, slotting and other post-processing steps, the white glaze layer in the middle forms a large contrast with the green body, showing the effect of "white line", Isolating the texture of the green body from the surface decoration layer cannot achieve the same decorative effect on the outside and inside of the ceramic, and it has become a flaw in the current conceptual product of the whole body ceramic tile
In foreign countries, in order to solve the problem of "white boundary", some ceramic tile manufacturers adopt the method of improving the formula of the green body and directly print on the green body; many domestic manufacturers and research institutions also have related research on this method, but it is limited by the raw materials of the green body. Due to factors such as characteristics, process requirements, and cost control, the direct printing process on blanks cannot achieve large-scale production in enterprises.
[0003] CN201610574716 discloses a manufacturing process for eliminating the white boundary line of colorful marble tiles and its colorful marble tiles. The pressed fabric layer is used instead of spraying make-up soil or primer, and after the fabric layer is pressed, an inkjet bleeding process is used for three-dimensional decoration. To achieve the effect of eliminating the white boundary line, in fact, subject to the influence of the uniformity of the thickness of the thin fabric and the degree of seepage and infiltration, in actual production, this process has poor stability in eliminating the white boundary line, and the pressing process is used instead of spraying glaze ,higher cost

Embodiment Construction
[0048] The present invention will be described in further detail below in conjunction with embodiment and accompanying drawing:
[0049] The white glaze of the whole body borderless ceramic tile includes the following raw materials by weight percentage:
[0050] Opacifier 75% Opacifier Frit 20% Clay 5%.
[0051] The opacifying agent is one or a combination of tin oxide, zirconium oxide, titanium oxide, cerium oxide, and ultrafine zirconium silicate.
[0052] The opacified frit adopts one or a combination of zirconium white opacified frit, zirconium-titanium opacified frit, phosphorus-zirconium composite opacified frit.
[0053] The preparation method of the whole-body borderless ceramic brick by rubber roller printing comprises the following steps:
[0054] (1) After the green body is formed, the surface of the green body is polished with a sponge material;
[0055] (2) After the polished green body has passed through the drying process, use rubber rollers to print white gl...

The invention relates to a white glaze, a whole body borderless ceramic brick containing the white glaze and a preparation method thereof. The white glaze includes the following raw materials in percentage by weight: 60-75% of opacifying agent, 15-28% of opacifying frit, and 4-15% of clay; the whole body borderless ceramic tile containing white glaze consists of a green body decorative layer, It is composed of white glaze layer, integrated decorative layer, transparent glaze or protective glaze layer. The preparation method includes: grinding the surface of the green body with a sponge material; after the drying process, printing a white glaze on the surface of the green body with a rubber roller, and the white glaze becomes a whole body borderless ceramic tile after being fired at 1100°C to 1200°C The white glaze layer; the white glaze weighs the material according to the formula, adds 45wt% printing oil, and ball mills until the fineness of the glaze slurry is less than 40 microns; adjust the viscosity of the glaze slurry to the Ennian viscosity of 18-23 seconds, and the specific gravity of the glaze slurry is 1.53-1.62.
Description
technical field [0001] The invention relates to the field of ceramics, in particular to a white glaze, a whole body borderless ceramic brick containing the white glaze and a preparation method thereof. Background technique [0002] In recent years, conceptual products such as full-body marble and full-body antique bricks in the architectural ceramics industry have won the favor of consumers. The whole-body products require that the surface of ceramic wall and floor tiles is basically consistent with the texture and tone of the interior of the body, so as to achieve the same appearance of ceramic tiles. One. However, in the production process of ceramic wall and floor tiles, the technical process of green body→applying make-up soil / underglaze→printing→applying transparent glaze / protective glaze is usually adopted. A layer of white glaze layer, the thickness is generally 0.2 ~ 0.4mm, after water jet cutting, chamfering, slotting and other post-processing steps, the white glaz...
