Problems solved by technology

At present, the ceramic rock plate on the mold surface is mainly realized by the following three processes: 1. Roller printing convex glaze on the surface of the flat body, the decorative effect is relatively simple, and the fineness of the mold pattern is limited; 2. Apply protective glaze after inkjet printing engraving ink , although it can form a three-dimensional engraved texture, it will cause the protective glaze to peel off. Therefore, the protective glaze has a relatively high firing temperature and high temperature viscosity, so that a high amount of protective glaze will lead to poor transparency and color development. Protective glaze A small amount of application will result in low engraving depth; 3. Using traditional mold pressing to prepare the mold surface rock plate has the defects of high mold opening cost and low quality rate, which seriously limits the application of this process in industrial production

preparation example Construction

[0048] The method for preparing a thin ceramic plate with an all-digital mold of the present invention achieves a three-dimensional mold effect through the all-digital inkjet printing technology, has a wider application range, can reduce the moisture introduced by the glaze line process, and prevent the thin ceramic plate body from being damaged by moisture. If it is too high, it will cause strength attenuation and cause rotten bricks. The green strength of the all-digital mold thin ceramic plate before being fired in the kiln is 1.20-1.60 MPa. In some embodiments, the moisture content of the all-digital mold thin ceramic plate before being fired in the kiln is 1-3%, preferably 1-2%.

[0049] The full digital mold thin ceramic plate obtained by the preparation method of the present invention has a mold texture depth of 0.5-3.0 mm. The depth of the mold texture is specifically the depth from the mold texture in the direction from the surface (plate surface) to the bottom.

Embodiment 1

[0052] Step (1): dry-pressing by a press to prepare a thin ceramic plate blank;

[0053] Step (2): drying the green body, the drying time is 0.5-1 h, and the moisture content of the green body after drying is controlled within 0.3-0.5 wt%;

[0054] Step (3): multi-channel inkjet printing primer on the surface of the dried green body; the chemical composition of the primer includes: in terms of mass percentage, SiO 2 : 55 to 60%, Al 2 O 3 : 23 to 27%, Fe 2 O 3 : 0.16 to 0.46%, TiO 2 : 0.15 to 0.25%, CaO: 0.1 to 0.7%, MgO: 0.1 to 0.5%, K 2 O: 1.0 to 4.5%, Na 2 O: 2.0 to 4.5%, ZrO 2 : 5.0~10.0%, Ignition loss: 3.0~4.0%; The specific gravity of the bottom glaze is 1.73~1.83g / cm 3 , the application amount is 200~400g / m 2 ; The number of print channels is 2 to 4 channels;

[0055] Step (4): double-channel inkjet printing digital top glaze on the surface of the green body after inkjet printing of the primer; the chemical composition of the digital top glaze includes: in ter...

Abstract

The invention discloses an all-digital mold thin ceramic plate and a preparation method thereof. The preparation method completely realizes the mold texture effect on the surface of the flat body by inkjet printing; the preparation method comprises the following steps: inkjet printing a primer on the surface of the flat body of a thin ceramic plate to form a concave-convex mold texture; inkjet printing the bottom The surface of the glazed body is inkjet-printed with a digital surface glaze; the inkjet-printed body after the inkjet-printed digital surface glaze is inkjet-printed with a pattern; the inkjet-printed body after the inkjet-printed pattern is inkjet-printed with protective ink; and fired. The method effectively controls the moisture content brought in by the glaze through an all-digital process, ensures the running strength of the body on the glaze line, and the process has extremely strong practicability.

Description

technical field [0001] The invention relates to an all-digital mold thin ceramic plate and a preparation method thereof, and belongs to the technical field of building ceramics production and manufacture. Background technique [0002] With the rapid development of the global ceramic industry and the prevalence of whole-house customization in the home improvement industry, a slate boom has emerged across the country, and domestic slate has formed a situation of contention among a hundred schools of thought. At present, the ceramic slate on the mold surface is mainly realized by the following three processes: 1. Roller printing convex glaze on the surface of the flat body, the decorative effect is relatively simple, and the fineness of the mold pattern is limited; 2. After inkjet printing engraving ink, a protective glaze is applied , although it can form a three-dimensional carving texture, it will cause the protective glaze to peel off, so the protective glaze has a relative...
