Abstract

The invention discloses a ceramic product with a crocodile scale appearance effect. A preparation method comprises the following steps: a blank is prepared; a first glaze layer composed of iron oxide, zirconium oxide, vanadium pentoxide, antimony trioxide, feldspar, clay, limestone, quartz and talc is sprayed; a cotton gauze impregnated with stearic acid paste is pasted; a second glaze layer composed of feldspar, clay, limestone, quartz, talc, calcium phosphate, iron oxide and zirconium oxide is applied by soaking; a third glaze layer composed of cobalt oxide, nickel oxide, chromium trioxide, zirconium oxide, iron oxide, manganese dioxide, feldspar, clay, limestone, quartz and talc is sprayed; and roasting is carried out, such that a finished product is obtained.

Description

Ceramic glaze is formed the method for crocodile skin scale appearance effect

Technical field

The present invention relates to the manufacture method of ceramic, on Ceramic glaze, specifically form the method for crocodile skin scale appearance effect.

Background technology

Domestic ceramics art ceramics is due to cosmetic requirement, various concavo-convex lines, plate, pattern or embossment is made on surface, existing method roughly two kinds, one forms concavo-convex lines, curved surface when making biscuit of ceramics, and this way lines are simple, lack natural sense, another kind is that sintering procedure transmutation in glaze paint is formed concavo-convex, but concavo-convex position occurs at random, can not carry out expecting and controlling, therefore can not form the ceramic with simulation crocodile skin scale appearance effect.

Summary of the invention

The object of the present invention is to provide a kind of ceramic with crocodile skin scale appearance effect.

The present invention includes following step:

A. ceramic biscuit is made;

B. the first glaze layer is sprayed, first glaze layer is by weight percentage by ferric oxide 5-8%, zirconium white 10-20%, Vanadium Pentoxide in FLAKES 6-12%, antimonous oxide 4-8%, albite or potassium felspar sand 10-15%, clay 10-20%, Wingdale 10-20%, quartz 8-15%, talcum 10-18% is formed, and the first glazed thickness is 0.05-0.1mm;

C. soak containing stearic acid 5-15% by cotton gauze, sodium hydroxide 1-3%, vanadic acid sodium 0.5-2%, surplus is dry after the lotion of water, is pasted onto on biscuit;

D. soak by weight percentage by albite or potassium felspar sand 12-18%, clay 15-25%, Wingdale 10-20%, quartz 8-15%, talcum 15-30%, calcium phosphate 10-20%, the second glaze layer that ferric oxide 1-3% and zirconium white 3-5% form, the second glazed thickness is 0.5-1mm;

E. spray by weight percentage by cobalt oxide 2-3%, nickel oxide 3-5%, chromium sesquioxide 3-5%, zirconium white 2-4%, ferric oxide 3-5%, Manganse Dioxide 3-5%, albite or potassium felspar sand 10-20%, clay 15-25%, Wingdale 10-20%, quartz 8-15%, the 3rd glaze layer that talcum 15-20% forms, the 3rd glazed thickness is 0.02-0.06mm;

F. roasting: intensification per hour 100-120 DEG C below 800 DEG C, 800-1200 DEG C of intensifications per hour 80-100 DEG C, 1200-1250 DEG C of insulations stopped heating after 20-60 minutes, and naturally cooling, becomes finished product.

Preferably: the first glaze layer mass percent consists of: ferric oxide 6%, zirconium white 14%, Vanadium Pentoxide in FLAKES 8%, antimonous oxide 6%, albite 12%, clay 15%, Wingdale 15%, quartz 10%, talcum 14%.

Preferably: the second glaze layer mass percent consists of: albite 15%, clay 20%, Wingdale 15%, quartz 10%, talcum 20%, calcium phosphate 14%, ferric oxide 2%, zirconium white 4%.

Preferably: the 3rd glaze layer mass percent consists of: cobalt oxide 2.5%, nickel oxide 3.5%, chromium sesquioxide 3.5%, zirconium white 2.5%, ferric oxide 4%, Manganse Dioxide 4%, albite 15%, clay 20%, Wingdale 15%, quartz 10%, talcum 18%.

The finished product that the present invention obtains is brownish black, has latticed gully, and be projection beyond gully, projection corner is round and smooth, and touch with hand and do not cut feel feel, the gully degree of depth about 0.5-1mm, gully color is slightly deeper than projection, has crocodile skin scale appearance effect.

Embodiment

Embodiment 1

Making ceramic biscuit, is diameter 15cm, the pen container totally 20 of height 20cm.

By weight percent:

Ferric oxide 6%, zirconium white 14%, Vanadium Pentoxide in FLAKES 8%, antimonous oxide 6%, albite 12%, clay 15%, Wingdale 15%, quartz 10%, the material ball milling of talcum 14%, cross 200 mesh sieves, the glaze slip of the furnishing solid content 50% that adds water, biscuit sprays glaze slip, become the first glaze layer, the first glazed thickness is about 0.08mm.

900ml water is heated to 80 DEG C, adds 20 grams of sodium hydroxide, vanadic acid sodium 10 grams, add 100 grams of stearic acid after dissolving, stir into paste, dry after cotton gauze being soaked lotion, paste coated by the biscuit executing the first glaze layer, cotton gauze is pasted onto on biscuit and forms square node, dry.

By weight percent: albite 15%, clay 20%, Wingdale 15%, quartz 10%, talcum 20%, calcium phosphate 14%, ferric oxide 2%, the material mixing grinding of zirconium white 4%, crosses 200 mesh sieves, add water and be made into second glaze slip of solid content 30wt%, take out after biscuit being immersed the second glaze slip and dry, take out after again immersing the second glaze slip and dry, repeatedly until the second glazed thickness is about 0.7mm.

By weight percent: cobalt oxide 2.5%, nickel oxide 3.5%, chromium sesquioxide 3.5%, zirconium white 2.5%, ferric oxide 4%, Manganse Dioxide 4%, albite 15%, clay 20%, Wingdale 15%, quartz 10%, the material mixing ball milling of talcum 18%, cross 200 mesh sieves, add water and be made into the 3rd glaze slip of solid content 45wt%, biscuit sprays the 3rd glaze slip, after dry, form the 3rd glaze layer of thickness 0.04mm.

Biscuit after glazing is put into kiln roasting, intensification per hour 100 DEG C below 800 DEG C, 800-1200 DEG C of intensifications per hour 80 DEG C, 1250 DEG C of insulations stopped heating after 0.5 hour, and naturally cooling, becomes finished product.

Finished product is brownish black, has latticed gully, and be projection beyond gully, projection corner is round and smooth, and touch with hand and do not cut feel feel, the gully degree of depth is about 0.7mm, and gully color is slightly deeper than projection, and even on projection have light arc colo(u)r streak, has crocodile skin scale appearance effect.
