Problems solved by technology

The first two technologies have high requirements on equipment and high decoration costs: the third method directly forms a metallized glaze by preparing glaze components without changing the firing system of the existing sanitary ceramic tunnel kiln.
At present, this glaze is only used in wall and floor tiles, and has not been mass-produced in the domestic sanitary ceramics field; similar research

Embodiment 1～9

[0017] Embodiments 1-9: The copper-colored metallic luster glaze is prepared by using the following raw materials and methods.

[0018] 1. Raw materials: albite, calcined kaolin, alumina, talc, zinc oxide, boron frit, cristobalite, crystallizer, catalyst, crystallizer, catalyst; of which:

[0019] Crystallization agent: a crystallization agent that forms metallic luster, composed of P-Fe system, does not contain toxic substances such as lead and chromium, preferably iron phosphate;

[0020] Catalyst: A crystallization accelerator that promotes the formation of metallic luster, which can make the glaze layer form a relatively stable spinel crystal structure. It is composed of P-Al system and does not contain toxic substances such as lead and chromium. It is best to use aluminum phosphate;

[0021] Cristobalite: 25wt% to 30wt% with a particle size composition of ≤10μm, 15wt% to 20wt% with a particle size of ≤5μm, and 3wt% to 6wt% with a particle size of ≤2μm.

Abstract

The invention discloses a purple bronze glaze with metallic luster and a preparation method thereof. The purple bronze glaze with metallic luster is prepared from the following raw materials by weight through sintering: 4 to 12% of a ceramic catalyst, 20 to 28% of a crystallization agent, 2 to 6% of cristobalite, 32 to 58% of albite, 2 to 6% of calcined kaolin, 1 to 5% of alumina, 6 to 16% of calcined talcum, 2% of zinc oxide and 5% of high-boron frit, wherein the ceramic catalyst is a P-Al catalyst, and the crystallization agent is a P-Fe crystallization agent. According to the invention, chemical composition of a formula is reasonably adjusted, the leadless P-Al catalyst and the P-Fe crystallization agent are employed, a stable spinel crystal structure is obtained through recrystallization of the glaze, metal coloring ions (Fe<2+> and Zn<2+>) and the like are enriched on the surface of a glaze layer, so the whole surface of the glaze presents metal-like luster. The glaze shows a purple bronze metal effect, and the hardness of the glaze is almost equal to the glaze of common sanitary china; acid resistance and alkaline resistance of the glaze reach national standards in China; and defects like pin holes and small holes of the glaze are substantially improved, and the glaze is applicable to production under conventional production kiln condition.

Description

technical field [0001] The invention relates to a ceramic glaze, in particular to a copper-colored metallic luster glaze of sanitary ceramics and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and requirements for the living environment, there are higher decorative requirements for the glazed surface of sanitary ceramics. Due to the elegant and luxurious artistic effect of metal decorative materials, glazed surfaces with metallic luster are becoming more and more popular. At present, there are three methods of making metallic luster glaze: 1. Sputtering molten metal coating directly on the ceramic body; 2. 3. Coating a coating containing metal or metal compound powder on the glaze of ceramic products, and undergoing reduction heat treatment to form a metallized decorative layer; 3. Prepare a glaze with a specific composition, and after firing, produce an imitation metallic luster glaze with a metallic luster in...
