preparation example Construction

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

[0023] 1) Pre-calcine the ferrophosphorus material alone or after mixing;

[0024] 2) Pulverize the pre-fired ferrophosphorus material and ceramic-based glaze raw materials, 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 golden yellow metallic luster glaze.

[0027] The pre-calcination temperature of the ferrophosphorus material is 500-1000°C.

[0028] Preferably, the amount of the binder added is 0.3-0.5% of the total mass of the ferrophosphorus material and the ceramic-based glaze, and the binder is preferably sodium carboxymethyl cellulose. Of course, those skilled in the art can also choose other adhesives as needed.

[0029] Preferably, the amount of the debonding agent added is ...

Embodiment 1

[0033] 1) 45 parts of ferrophosphorus materials, including 35 parts of sodium ferric pyrophosphate and 10 parts of iron orthophosphate, were pre-calcined at 500 ° C, and then the pre-fired materials were crushed;

[0034] 2) Mix the pulverized ferrophosphorus pre-fired material and 45 parts of crushed ceramic-based glaze, add 0.4% CMC and 0.2% sodium tripolyphosphate of the total mass of the ferro-phosphorous material pre-fired material and ceramic-based glaze, of which the ceramic The base glaze is composed of 20 parts of albite, 10 parts of quartz, 5 parts of limestone and 10 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 for 24 hours, and obtain a low-temperature golden yellow Gold metallic luster glaze.

Embodiment 2

[0037] 1) 25 parts of 40 parts of ferrophosphorus sodium iron pyrophosphate and 15 parts of iron orthophosphate were pre-calcined at 1000°C, and then the pre-baked materials were pulverized;

[0038] 2) Mix the pulverized ferrophosphorus material and 65 parts of pulverized ceramic-based glaze, add 0.5% CMC and 0.2% sodium tripolyphosphate to the total mass of the phosphorus-iron material and ceramic-based glaze, wherein the composition of the ceramic-based glaze is sodium Composed of 45 parts of feldspar, 8 parts of quartz, 6 parts of limestone, and 6 parts of kaolin;

[0039] 3) According to the material: water = 100:90, 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 for 24 hours, and obtain a low-temperature golden yellow Gold metallic luster glaze.

Abstract

The invention discloses low-temperature golden yellow metallic luster glaze and a manufacturing method thereof. The low-temperature golden yellow metallic luster glaze comprises a ferro phosphorus material and ceramic-based glaze in a mass ratio of 0.5-1:1, wherein the ferro phosphorus material consists of sodium ferric pyrophosphate and ferric phosphate or the sodium ferric pyrophosphate and a mixture of ferric oxide and aluminum phosphate; and the ceramic-based glaze comprises albite, quartz, limestone and kaolin in a weight ratio of 20-50:5-10:2-8:3-10. The low-temperature golden yellow metallic luster glaze has the advantages of a few types of raw materials, low manufacturing cost, one-time sintering at a low temperature, contribution to energy conservation and environmental protection, bright golden yellow metallic luster of the sintered product, obvious decorative effect and wide application range; and the method is particularly suitable for manufacturing ceramic wall tiles, ceramic waist lines, ceramic mosaic and the like with golden yellow appearance.

Description

technical field [0001] The invention relates to a metallic luster glaze, in particular to a low-temperature golden yellow 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 r...
