preparation example Construction

[0022] The preparation method of the above-mentioned low-temperature silver-white metallic luster glaze comprises the following steps:

[0023] 1) Sodium ferric pyrophosphate and ferric orthophosphate are pre-calcined separately or mixed;

[0024] 2) Crush the pre-fired sodium ferric pyrophosphate, ferric orthophosphate and ceramic-based glaze, and mix them evenly;

[0025] 3) Add binder and debonding agent, stir and mix evenly to obtain a mixture;

[0026] 4) Add water to the mixture, and ball mill it into a slurry to obtain a low-temperature silver-white metallic luster glaze.

[0027] The calcining temperature of sodium ferric pyrophosphate and ferric orthophosphate is 500-1000°C.

[0028] Preferably, the amount of the binder added is 0.3-0.5% of the total mass of sodium ferric pyrophosphate, iron orthophosphate and ceramic-based glaze, and the binder is preferably sodium carboxymethylcellulose. Of course, those skilled in the art can also choose other adhesives as neede...

Embodiment 1

[0033] 1) 15 parts of sodium ferric pyrophosphate and 7 parts of iron orthophosphate were pre-calcined at 500 ° C, and then the pre-fired materials were pulverized;

[0034] 2) Mix crushed sodium ferric pyrophosphate, ferric orthophosphate and 28 parts of crushed ceramic-based glaze, add 0.4% of CMC and 0.2% of tripolyphosphoric acid to the total mass of sodium ferric pyrophosphate, ferric orthophosphate and ceramic-based glaze Sodium, wherein the composition of the ceramic base glaze is 20 parts of albite, 2 parts of quartz, 2 parts of limestone, and 4 parts of kaolin;

[0035] 3) According to the material: water = 100:80, add water, ball mill, control the fineness of the slurry to 325 mesh, the sieve residue is 1% smaller, adjust the specific gravity of the slurry to about 1.4, homogenize into a glaze slurry in 24 hours, and obtain a low-temperature silvery white Metallic glaze.

Embodiment 2

[0037] 1) 20 parts of sodium ferric pyrophosphate and 9 parts of ferric orthophosphate were pre-calcined at 700 ° C, and then the pre-fired materials were pulverized;

[0038] 2) Mix the crushed sodium ferric pyrophosphate, ferric orthophosphate and 63 parts of crushed ceramic-based glaze, add 0.5% CMC and 0.3% tripolyphosphoric acid to the total mass of sodium ferric pyrophosphate, ferric orthophosphate and ceramic-based glaze Sodium, wherein the composition of the ceramic base glaze is 50 parts of albite, 2 parts of quartz, 1 part of limestone, and 10 parts of kaolin;

[0039] 3) According to the material: water = 110:90, add water, ball mill, control the fineness of the slurry to 325 mesh, the sieve residue is 1% smaller, adjust the specific gravity of the slurry to about 1.4, homogenize into a glaze slurry in 24 hours, and obtain a low-temperature silvery white Metallic glaze.

Abstract

The invention discloses a low-temperature glaze with silver white metal luster, which comprises ferrisodium pyrophosphate, ferric phosphate and ceramic-based glaze according to the ratio of (2-3):1:(4-7), wherein the ceramic-based glaze comprises the components of soda feldspar, quartz, limestone and kaolin according to the weight ratio of (20-50):(2-5):(0-2):(3-10). The low-temperature glaze has the advantages of fewer raw material kinds, wide resources, low cost, identical manufacturing process with common over glaze, low cost, simple use method, one-time baking, low baking temperature, energy saving and environmental protection. The baked product has beautiful silver white metal luster and is especially applicable to ceramic wall tiles, ceramic mosaic tiles and the like, and the decoration effect is good.

Description

technical field [0001] The invention relates to a metallic luster glaze, in particular to a low-temperature silver-white metallic luster glaze and a preparation method thereof. Background technique [0002] Metal luster glaze is a new type of decorative glaze. When used on ceramic products, it can not only produce a metal-like elegant and gorgeous appearance, but also enhance the chemical stability of the ceramic glaze and its resistance to acid and alkali. In recent years, the research on metallic luster glaze has attracted more and more people's interest, and its application scope has gradually expanded, covering daily necessities decoration, architectural decoration, ceramics and other industries. [0003] At present, there are three methods for preparing metallic luster glaze: ① direct sputtering molten metal coating on the ceramic body; ② coating the glaze surface of ceramic products with a coating containing metal or metal compound powder, and undergoing reduction heat...
