Problems solved by technology

This process adopts spray crystal colored base glaze, then uses screen to print crystallization agent frit dry particles, and then uses screen printing transparent or colored dry particles to be quickly fired in roller kiln to obtain antique bricks with crystal flower effect of different colors , but this process cannot combine the crystal flower effect with modern inkjet printing technology, the glaze decoration effect is single, and the texture effect of modern ceramic tiles cannot be reflected
This invention introduces a large amount of lithium carbonate and soda ash with low initial melting point and low-strength fluxing. Although titanium and zirconium crystal nucleating agent components are introduced, due to the use of the above-mentioned low initial melting point materials, it can only be applied to the crystalline glaze effect on the natural surface.

Embodiment 1

[0065] Step 1: Press the adobe. The green body is obtained by pressing the ceramic base material commonly used in the field.

[0066] Step 2: Dry the green body, the drying time is 60 minutes, and the moisture content of the dried green body is controlled within 0.5%.

[0067] Step 3: Spray the ink-jet colored glaze on the dried brick by spraying glaze. The mineral composition of the ink-jet colored glaze is: potassium feldspar: 43%, albite: 15%, kaolin: 27%, Calcined alumina: 5%, zirconium silicate: 8%. The chemical composition of the inkjet color glaze is: SiO 2 : 57.68%, Al 2 o 3 : 23.57%, Fe 2 o 3 : 0.4%, TiO 2 : 0.07%, CaO: 0.34%, MgO: 0.22%, K 2 O: 5.21%, Na 2 O: 2.39%, ZrO 2 : 6.46%, loss on ignition: 3.38%. The specific gravity of the glaze is 1.45, and the amount of sprayed glaze is 480g / m 2 .

[0069] Step 5: Use the digital glue dry granulator to print the glue pattern, and...

Embodiment 2

[0078] The difference from Example 1 is that the raw material composition of the crystal nucleating agent is: potassium feldspar: 20%, albite: 10%, quartz: 12%, alumina: 1%, calcite: 16%, oxide Zinc: 10%, Fluorite: 2%, Boric Acid: 2%, Calcium Phosphate: 1.5%, Rutile: 16%, Zircon Powder: 8%, Tungsten Oxide: 1.5%. The chemical composition of the nucleating agent is: SiO 2 : 38.75%, Al 2 o 3 : 6.40%, Fe 2 o 3 : 0.10%, TiO 2 : 16.92%, CaO: 11.33%, MgO: 0.28%, K 2 O: 1.95%, Na 2 O: 1.74%, ZnO: 10.58%, F: 0.82%, ZrO 2 : 5.56%, P 2 o 5 : 0.72%, B 2 o3 : 1.18%, WO 3 : 1.59%, loss on ignition: 1.76%.

[0079] Figure 4 The photo of the brick surface of the ceramic brick prepared in Example 2 shows that the brick surface not only has a brightly colored stone texture pattern, but also has some white fixed-point three-dimensional crystal flower effect pattern layers.

Abstract

The invention discloses a nucleating agent and a positioning crystal pattern ceramic tile prepared from the nucleating agent. The nucleating agent is prepared from the following raw materials by mass:15-25% of potassium feldspar, 5-15% of albite, 10-14% of quartz, 0.5-1.5% of aluminum oxide, 14-18% of calcite, 8-12% of zinc oxide, 1-3% of fluorite, 1-3% of boric acid, 1-2% of calcium phosphate, 15-17% of rutile, 7-9% of zircon powder and 1-2% of tungsten oxide.

Description

technical field [0001] The invention relates to a crystal nucleating agent for positioning crystal flower ceramic bricks and a method for using the same, belonging to the technical field of ceramic brick production and manufacture. Background technique [0002] In recent years, the production technology of architectural ceramics has developed rapidly, and various new processes and new formulas have been continuously applied. The refinement and personalization of the decoration effect of wall and floor tiles has become an urgent need for ceramic enterprises to achieve product differentiation. Crystal flower glaze is a kind of high-grade artistic glaze that forms beautiful pattern effects on the glaze surface by precipitating crystals in the glaze. Its unique artistic decoration effect is of great ornamental value and is very popular in the market. It is mainly used in daily-use ceramics. [0003] Chinese patent CN104311155 A discloses a crystalline glazed ceramic tile and its...
