Problems solved by technology

For example, the Chinese patent CN2628631Y announced on July 28, 2004 discloses a metal oxide film decorative ceramic tile. Although its metal color is bright, it has a complicated process and requires a high firing temperature when firing on the ceramic surface. The shortcoming of high cost; a kind of frit metal glaze disclosed in Chinese patent CN101024582A announced on August 29, 2007, the process is simple, but the color is not as good as the former and the firing temperature after laying on the brick surface is also higher (above 1150 ° C)

Embodiment 1

[0011] Embodiment 1: Taking the preparation of 1000kg metallic luster glaze as an example, its concrete steps are as follows:

[0012] A. Weigh 292.1kg of quartz, 38.1kg of kaolin, 50.8kg of feldspar, 203.2kg of red lead, and 50.8kg of calcium carbonate, mix them evenly, put them into a glass-like substance calcined at high temperature in a container, and crush them into small particles of 200-250 mesh ;

[0013] B. Add the following weight of 200-250 mesh colored metal oxides to A granules, 25kg copper oxide, 80kg nickel oxide, 80kg cerium oxide, 120kg manganese dioxide, 60kg titanium dioxide, mix and pack uniformly to obtain a metallic luster glaze.

[0014] Put it into the mill according to the ratio of metallic luster glaze: ball: water = 1:2:1, and add an appropriate amount of additives (sodium tripolyphosphate, sodium carboxymethylcellulose) to adjust the performance of the glaze slurry. Milling fineness: sieve through 250-mesh sieve < 0.2%, use glazing equipment to app...

Abstract

The invention belongs to the porcelain glaze material technical field, in particular to a porcelain glaze material and a method for manufacturing the same. In the invention, quartz, kaolin, red lead, feldspar and calcium carbonate are evenly mixed and calcined at a high temperature of between 1,250 and 1,400 DEG C to generate a glassy material, and the glassy material is crushed into particles with the particle diameter of between 200 and 250 meshes, and is mixed with particle coloring metal oxides to manufacture the porcelain glaze material. The invention better considers the two technical problems of improving the metal luster effect and lowering the burning temperature of glaze materials; moreover, the invention has the advantages of simple process, low cost and obvious energy saving effect.

Description

technical field [0001] The invention relates to a method for preparing a glaze for ceramics, in particular to a method for preparing a glaze capable of exhibiting metallic luster, and belongs to the technical field of ceramic glazes. Background technique [0002] "Glaze" refers to a thin layer of glass-like substance covering the surface of the ceramic body, its thickness is usually 0.2-0.8mm, it can improve the surface properties of the ceramic body, such as reducing the surface porosity, making the surface It can be smooth and increase the mechanical strength of the product and improve the chemical corrosion resistance of the surface, while beautifying the appearance of the product. Ceramic glazes are generally divided into low-temperature glazes, medium-temperature glazes and high-temperature glazes according to the firing temperature of the glazes, and are divided into matte glazes, semi-glossy glazes and glossy glazes according to optical properties. With the developme...
