Embodiment 1

[0061] This embodiment provides a bottom glaze, the raw material composition of the bottom glaze includes: 5 parts of kaolin, 33 parts of potassium feldspar, 28 parts of albite, 10 parts of quartz powder, 10 parts of zirconium silicate, 7 parts of talcum powder, 7 parts of 965 frit.

[0062] The chemical composition of the 965 frit includes in mass percent: SiO 2 49.97%, Al 2 o 3 16.96%, Fe 2 o 3 0.14%, TiO 2 0.05%, CaO 12.71%, MgO 1.41%, K 2 O 4.03%, Na 2 O 12.57%, ZnO 0.37%, B 2 o 3 0.18%, BaO 0.83%, loss on ignition 0.78%.

[0063] It can be understood that by controlling the amount of kaolin added, the infiltration depth and infiltration efficiency of the ink are increased when the inkjet printing decoration is performed on the bottom glaze, thereby improving the drying efficiency of the ink, and effectively avoiding the The avoidance of glaze defects after inkjet printing significantly improves the appearance consistency of black inkjet ceramic tiles.

Embodiment 2

[0065] This embodiment provides a bottom glaze, the raw material composition of the bottom glaze includes: 7 parts of kaolin, 33 parts of potassium feldspar, 33 parts of albite, 13 parts of quartz powder, 8 parts of zirconium silicate, Calcined soil 1 part, wollastonite 2 parts, zinc oxide 3 parts. It can be understood that by controlling the amount of kaolin added, the rate of infiltration of the ink is accelerated when the inkjet printing decoration is carried out on the bottom glaze, which effectively improves the drying efficiency of the ink, and then effectively The glaze avoidance defect after inkjet printing is avoided; at the same time, by replacing the talcum powder with wollastonite and zinc oxide, the melting effect of inkjet printing ink on the bottom glaze is effectively improved, and while the glaze avoidance defect is solved, Significantly improves the hair color effect of the ink.

Embodiment 3

[0067] see figure 1 , the present embodiment provides a method for preparing a bottom glaze, which includes,

[0068] Step S11, weighing the raw materials of the bottom glaze, and mixing the components to obtain the raw material mixture of the bottom glaze;

[0069] Step S12, according to the mass percentage of the obtained bottom glaze raw material mixture, respectively weigh 0.12% of CMC, 0.4% of sodium tripolyphosphate and 0.05% of preservative, and mix them with the bottom glaze raw material mixture to obtain the bottom glaze before ball milling. material;

[0070] Step S13, according to the weight ratio of the bottom glaze ball milling material: ball: water = 1:2:0.4, perform wet ball milling on the bottom glaze ball milling material, and control the glaze slurry after ball milling to pass through a 325-mesh sieve with a residue of 0.1 %-0.3%, get the bottom glaze.

[0071] Wherein, the raw material composition of the bottom glaze includes in terms of mass fraction: 5 ...

Abstract

The invention discloses a ground glaze and a preparation method thereof, as well as a black ink-jet ceramic tile and a manufacturing method thereof. The ground glaze is prepared from the raw materialcompositions in parts by mass: 5 parts of kaolin, 33 parts of potassium feldspar, 28 parts of albite, 10 parts of quartz powder, 10 parts of zirconium silicate, 7 parts of talcum powder and 7 parts ofa 965 frit. The 965 frit is prepared from the chemical compositions in percentage by mass: 49.97% of SiO2, 16.96% of Al2O3, 0.14% of Fe2O3, 0.05% of TiO2, 12.71% of CaO, 1.41% of MgO, 4.03% of K2O, 12.57% of Na2O, 0.37% of ZnO, 0.18% of B2O3, 0.83% of BaO and 0.78% of losses on ignition. By controlling the adding amount of the kaolin, the penetration depth of ink is increased, the drying efficiency of the ink is improved, and the defect of avoiding glazes after ink-jet printing is overcome.

Description

technical field [0001] The invention relates to the production field of black ink-jet ceramic bricks, in particular to a bottom glaze and a preparation method thereof, black ink-jet ceramic bricks and a production method thereof. Background technique [0002] At present, popular black inkjet ceramic tile products such as black gold flower and Lauren black gold on the market are generally decorated with screen or rubber roller printing and other printing technologies that are about to be eliminated; in order to improve production efficiency, inkjet printing is usually used to produce full tiles. Polished glazed black inkjet ceramic tiles; however, black inkjet ceramic tiles are dark in color, and the amount of black and blue ink is very large; because the ink is oily, and the glaze is water-based, when the amount of ink used is large, the ink will dry If it is not timely, when glaze is applied to the ink that is not completely dry, the glaze and ink will repel each other, res...
