Embodiment 1

[0017] A copper imitation luster ceramic glaze is composed of the following components in parts by weight: 55 parts of potassium albite feldspar, 10 parts of white glass, 20 parts of boric acid powder, 20 parts of ochre, 15 parts of potassium nitrate, 15 parts of glaze fruit, 15 parts of green glass, 3 parts of tin crystal material, and 1 part of copper oxide; the preparation steps are as follows: A, take the raw materials according to the weight portion, add the above raw materials into a pulverizer, and pulverize them to 300 mesh to obtain mixed particles; B, stir the mixed particles uniform, melted at 1350°C, and kept warm for 2 hours; C, quenched into a frit in water at a temperature of 15°C, and then ultrasonically vibrated for 5 minutes to obtain the copper-like luster ceramic glaze.

Embodiment 2

[0019] A copper imitation luster ceramic glaze is composed of the following components in parts by weight: 60 parts of potassium albite feldspar, 15 parts of white glass, 25 parts of boric acid powder, 25 parts of ochre, 20 parts of potassium nitrate, 20 parts of glaze fruit, 20 parts of green glass, 4 parts of tin crystal material, and 3 parts of copper oxide; the preparation steps are as follows: A, take the raw materials according to the weight portion, add the above-mentioned raw materials into a pulverizer, grind them to 320 mesh, and obtain mixed particles; B, stir the mixed particles uniform, melted at 1500°C, and kept warm for 4 hours; C, quenched into a frit in water at a temperature of 18°C, and then ultrasonically vibrated for 8 minutes to obtain the copper-like luster ceramic glaze.

Embodiment 3

[0021] A copper imitation luster ceramic glaze is composed of the following components in parts by weight: 57 parts of potassium albite feldspar, 12 parts of white glass, 22 parts of boric acid powder, 23 parts of ocher, 18 parts of potassium nitrate, 18 parts of glaze fruit, 17 parts of green glass, 3.5 parts of tin crystal material, and 2 parts of copper oxide; the preparation steps are as follows: A, take the raw materials according to the weight portion, add the above-mentioned raw materials into a pulverizer, and pulverize them to 310 mesh to obtain mixed particles; B, stir the mixed particles uniform, melted at 1450°C, and kept warm for 3 hours; C, quenched into a frit in water with a temperature of 16°C, and then ultrasonically vibrated for 6 minutes to obtain the copper-like luster ceramic glaze.

Abstract

The invention relates to a ceramic glaze with copper-like luster. The ceramic glaze is prepared from potassium feldspar, albite, white glass, boric acid powder, ochre, potassium nitrate, glaze stone,green glass, tin crystals and copper oxide. The ceramic glaze with copper-like luster has the advantages that a green body can be compact, gaps in the green body can be reduced, and mechanical strength and dielectric property of the green body can be improved. A proper amount of ochre is added, so that the ceramic glaze with copper-like luster can keep metal cluster continuously, has a good use effect, can be applied to building sanitary ceramics as well as surfaces of products such as concrete slabs, plastic plates, gypsum boards, paint, plastics, textiles and the like, is wide in applicationrange and has good popularization value; the preparation process of the ceramic glaze with copper-like luster is simple, the performance is stable, and the preparation cost of the ceramic glaze withcopper-like luster is low.

Description

technical field [0001] The invention relates to the technical field of ceramic manufacturing, in particular to a copper-imitating lustrous ceramic glaze. Background technique [0002] Glaze is a kind of silicate. The glaze applied on ceramics is generally made of quartz, feldspar, and clay. After grinding and adding water, it is coated on the surface of the green body and melted by roasting at a certain temperature. The temperature drops When, a glassy thin layer on the ceramic surface is formed. It makes ceramics increase mechanical strength, thermal stability, dielectric strength and prevent liquid and gas erosion. Glaze also has the functions of increasing the appearance of porcelain, making it easy to wash and wipe, and preventing it from being stained by dust. The ceramic industry can be roughly divided into the following categories according to the category and use of the product: lead glaze and lead-free glaze; raw glaze and frit glaze, ceramic tile, tableware, sani...
