Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of daily-use stoneware glaze, and particularly relates to a net-shaped relief glaze and a preparation method thereof. BACKGROUND

[0002] Daily-use ceramic mainly includes four categories of fine porcelain, stoneware, fine pottery and coarse pottery, and the main difference lies in the water absorption rate of ceramic formation. The water absorption rate of stoneware is between 0.5% and 3%, and the firing temperature is between 1160 and 1260 degrees Celsius. The stoneware is mainly decorated with color glaze, because the firing temperature is relatively low, and various inorganic ceramic pigments can be used, so the color glaze stoneware is popular in the world. The color glaze stoneware pursues new, strange and special decoration, and gives certain cultural connotation or other aesthetic will. The color glaze stoneware truly makes daily-use ceramic artistic, and makes artistic ceramic daily-used.

[0003] The patent application with the patent publication number CN104016722A discloses a reaction glaze with a relief effect, which comprises a base glaze and a surface glaze, and is characterized in that the base glaze comprises the following components and the mass fraction of each component is as follows: feldspar 31-35 parts, quartz 20-23 parts, calcite 12-15 parts, Guizhou soil 4-5 parts, zinc oxide 2.5-5 parts, zirconium silicate 8-10 parts, strontium carbonate 5-8 parts; the surface glaze comprises the following components and the mass fraction of each component is as follows: feldspar 23-25 parts, borax 20-25 parts, quartz 12-15 parts, calcite 15-18 parts, Guizhou soil 3-5 parts, zinc oxide 15-17 parts, zirconium silicate 8-10 parts, titanium oxide 9-10 parts, and color base 11-15 parts. The technical scheme can make the glaze surface present concave-convex feeling and have simple relief effect, but cannot realize complex relief effect and has limitations.

[0004] The patent application with the patent publication number CN104909832A discloses a gold metal glaze and a preparation method thereof, and the components of the gold metal glaze and the mass fraction of each component are as follows: potassium feldspar 35-40 parts, kaolin 5-8 parts, quartz 8-12 parts, high-expansion coefficient frit 3-5 parts, barium carbonate 4-7 parts, high-lead frit 15-25 parts, vanadium pentoxide 1-2 parts, manganese dioxide 10-12 parts, copper oxide 1-3 parts, and talc 1-2 parts. The patent is a surface glaze formula, high-lead powder is added to break the traditional lead-free metal glaze mode, the metal luster of the oxide can be more stable, but the relief effect is not achieved. Because of the lead content, the product is not suitable for export daily-use ceramic production, that is, the quality standard for export is not reached.

[0005] The special rubber roller or the printing screen plate with optimized screen mesh number is used in the prior art to print the special glaze on the body with the base glaze and the surface glaze, and the special glaze pattern is sunk in the common surface glaze after high-temperature firing. In view of the defects of the prior art, it is of great significance to research and develop a net-texture relief glaze to meet the current market demand. SUMMARY
