Problems solved by technology

Traditional glaze colors are mostly glazed with a smooth texture, accompanied by changes in color texture and other characteristics. This kind of glaze color can obtain a relatively strong psychological feeling in terms of visual experience, but on the tactile level, the touch of a single smooth glaze surface lacks layers. sense of change

Embodiment 1

[0021] A kind of black matte granular glaze, which is a mixed powder of 0.3% of the remainder of the multi-hole sieve, and includes the following components by weight percentage: SiO 2 58%, Al 2 o 3 19%, K 2 O3.4%, Na 2 O1.3%, CaO2%, MgO 0.5%, BaO11%, cobalt black 8.5%.

[0022] A preparation method of black matte granular glaze, the method comprises the following steps:

[0023] S1. Weigh each component according to the formula, and add water to grind, the excess of the glaze water is 0.4%, and the specific gravity of the water glaze is 1.65;

[0024] S2. Apply the glaze water on the surface of the biscuit body by spraying the glaze. The glaze spraying method adopts fine-point atomization, and the thickness of the glaze layer is controlled at 1.5mm. In the process of spraying the glaze, the amount of glaze per unit time is 85g / min, to ensure that the glaze water can be quickly absorbed by the biscuit body after being sprayed on the product, and it should not be sprayed ...

Abstract

The invention discloses black matte granular glaze, which is mixed powder containing 0.3-0.5% of million-hole sieve residues and comprises the following components in percentage by weight: 52%-58% of SiO2, 17.5%-21% of Al2O3, 3.4%-4% of K2O, 1%-1.3% of Na2O, 2%-5% of CaO, 0.5%-1.5% of MgO, 8.5%-11% of BaO and 8.5%-11% of cobalt black. The preparation method of the black matte granular glaze comprises the steps of S1, weighing the components according to the formula, adding water, and grinding until the million-hole sieve residue of the glaze water is 0.3-0.5% and the specific gravity of the water glaze is 1.65-1.68; S2, coating the surface of a biscuit firing green body with the glaze water in a glaze spraying glazing mode, wherein fine point atomization is adopted as a glaze spraying method, and the thickness of a glaze layer is controlled to be 1-1.5 mm; and S3, putting the biscuit firing green body subjected to glaze spraying into a kiln, heating to 1230-1250 DEG C, sintering for 8-12 hours, slowly cooling after sintering, and discharging from the kiln to prepare the black matte granular glaze which has the advantages of stable glaze color, high yield, concave-convex glaze surface, stereoscopic impression and the like.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a black matte granular glaze and a preparation method thereof. Background technique [0002] Black matte particle glaze belongs to medium temperature glaze color, the difference from traditional glaze color lies in the graininess of the product surface. Traditional glaze colors are mostly glazed with a smooth texture, accompanied by changes in color texture and other characteristics. This kind of glaze color can obtain a relatively strong psychological feeling in terms of visual perception, but on the tactile level, the touch of a single smooth glaze surface lacks layers. change of feeling. The black matte granular glaze, in addition to the color effect, further enhances the graininess of the glaze and improves the user's tactile experience. Contents of the invention [0003] The purpose of the present invention is to break through the limitation of the tactile feel...
