preparation example Construction

[0037] The embodiment of the second aspect of the present invention proposes a preparation method of lead-free metallic luster glaze, which is used to prepare the lead-free metallic luster glaze described in any of the above embodiments, such as figure 1 shown, including the following steps:

[0038] S1: mixing the basic glaze, the first coupler and the second coupler in proportion;

[0039] S2: The mixed glaze is wet-milled into a slurry with a ball mill, and the slurry is sieved to obtain a finished glaze;

[0040] S3: Cover the green body with the finished glaze, and fire at a temperature ranging from 1280° C. to 1330° C. for 8 hours to 12 hours.

[0041] The preparation method of the lead-free metallic luster glaze of the embodiment of the present invention, by selecting a reasonable formula composition, adopting high temperature one-time firing, produces uniformly sized crystal grains in the glaze layer, and can be adjusted by adding different rare earth oxides as requir...

Embodiment 1

[0054] The lead-free metallic luster glaze comprises the following components in terms of mass percentage: 89% of basic glaze, 6% of the first coupler, and 5% of the second coupler. Wherein, the first coupler is: Fe 2 o 3 , MnO, V 2 o 5 , NiO, the second coupler is: CeO 2 , Y 2 o 3 、Nd 2 o 3 , Yb 2 o 3 .

[0055] The basic glaze includes the following components in terms of mass percentage: 58.5% feldspar, 7% Suzhou kaolin, 18% quartz, 2% calcined talc, 12% calcite, and 2.5% bovine bone ash.

[0056] Preparation:

[0057] S1: mixing the basic glaze, the first coupler and the second coupler in the above ratio;

[0058] S2: Mix the mixed glaze, balls, and water in a ratio of 1:1.5:0.7, add a water reducer and a dispersant, ball mill for 10 hours, and pass the milled slurry through a 250-mesh sieve to obtain a finished glaze;

[0059] S3: Cover the finished glaze with a thickness of 0.5mm on the green body, dry the green body at a temperature of 60°C for 120 minutes ...

Embodiment 2

[0061] The lead-free metallic luster glaze comprises the following components in terms of mass percentage: 88% of basic glaze, 7% of the first coupler, and 5% of the second coupler. Wherein, the first coupler is: Fe 2 o 3 , CuO, MnO, V 2 o 5 , the second coupler is: La 2 o 3 , CeO 2 , Y 2 o 3 .

[0062] The basic glaze includes the following components in terms of mass percentage: 60% feldspar, 5% Suzhou kaolin, 24.3% quartz, 1.5% calcined talc, 8% calcite, and 1.2% bovine bone ash.

[0063] Preparation:

[0064] S1: mixing the basic glaze, the first coupler and the second coupler in the above ratio;

[0065] S2: Mix the mixed glaze, balls, and water in a ratio of 1:1.5:0.6, add a water reducing agent and a dispersant, ball mill for 12 hours, and pass the milled slurry through a 300-mesh sieve to obtain a finished glaze;

[0066] S3: Cover the finished glaze with a thickness of 0.35mm on the green body, dry the green body at a temperature of 50°C for 200 minutes aft...

Abstract

The invention relates to a lead-free metallic luster glaze and ceramic thereof, and a preparation method of the lead-free metallic luster glaze. The lead-free metallic luster glaze comprises the following components: 88%-96% of basic glaze; 3%-11% of a first coloring agent, including at least two of Fe2O3, CuO, MnO, V2O5 and NiO; 1-5% of a second coloring agent comprising at least two of Pr2O3, Sm2O3, La2O3, CeO2, Y2O3, Nd2O3 and Yb2O3. According to the lead-free metallic luster glaze, by adding a second color former into a mixed glaze of a basic glaze and a first color former, the surface metallic luster of the lead-free metallic luster glaze is improved; wherein the first color former comprises at least two of Fe2O3, CuO, MnO, V2O5 and NiO, that is, the lead frit is not added, so that environmental pollution and damage to production workers in the production process of the glaze are avoided, and the lead-free metallic luster glaze is prevented from being eroded by acid in the use process to dissolve out lead elements and seriously endanger human health.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a lead-free metallic luster glaze and ceramics with the lead-free metallic luster glaze, and a preparation method of the lead-free metallic luster glaze. Background technique [0002] Metal luster glaze is a new type of ceramic art glaze. It not only has elegant, luxurious and solemn artistic effects, but also has low cost, high glaze hardness and good chemical stability. The architectural ceramic products decorated with it have realistic metal Decorative effect, therefore, ceramic products with metallic luster are more and more favored by consumers. [0003] In the prior art, mostly lead-boron basic glazes are used to prepare metallic luster glazes. Lead-containing frit has the advantages of good high-temperature fluidity, high gloss and smoothness, wide firing range, and good adaptability to blank glaze. The formation has a good promoting effect. However, lead i...
