Description

A preparation method of colored exquisite porcelain Technical Field

[0001] The invention relates to the technical field of traditional ceramics, in particular to a method for preparing colored exquisite porcelain. Background Art

[0002] Linglong porcelain is a porcelain object carved through a hollowing process, creating numerous regularly arranged "Linglong eyes." Glazed and fired, these holes transform into translucent, beautiful pores, earning it the nickname "porcelain with glass." However, due to the limitations of traditional production techniques, the "Linglong eyes" of Jingdezhen Linglong porcelain are mostly monochromatic. With the advancement of ceramic production technology, the size of "Linglong eyes" has increased. The current monochromatic decorative techniques no longer meet the demand for large-scale Linglong porcelain and meet people's demand for a higher quality of life. Technological innovation is urgently needed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a method for preparing colored exquisite porcelain with unique preparation process, low cost and brilliant colors.

[0004] The technical solution of the present invention is: a method for preparing colored exquisite porcelain, characterized by following the steps:

[0005] Step 1: Prepare high plasticity ceramic body mud and form the body by slip injection or rolling;

[0006] Step 2: Paste exquisite decorative patterns on the surface of the blank prepared in step 1, and spray exquisite holes using a sandblasting process;

[0007] Step 3: Apply transparent glaze 1 to the inner surface and the exquisite holes of the body prepared in step 2, then fire the glaze at 1250°C, take it out of the kiln, and obtain the glazed body;

[0008] Step 4: Use ceramic pigments to paint and decorate the outer glaze surface of the exquisite hole prepared in step 3;

[0009] Step 5: Apply transparent glaze 2 to the outer surface of the glaze body after the painting and decoration in step 4, then fire the glaze at 1280-1310℃, take it out of the kiln, and obtain colorful exquisite porcelain.

[0010] The weight percentage composition of the green body mud in the step 1 is: 56% Nangang porcelain stone, 8% Xingzi kaolin, 8% Sanbaopeng porcelain stone, 4% Guangfeng talc, 9% calcite, and 15% Donghai quartz.

[0011] The shape of the exquisite hole in step 2 is one or more of circular, elliptical, and polygonal, and the area of ​​a single exquisite hole is 0.5 to 5 cm 2 .

[0012] The weight percentage composition of the transparent glaze 1 in step 3 is: Yingkou feldspar 36%, Sanbaopeng porcelain stone 9%, Donghai quartz 35%, Guangfeng talc 5%, alumina 10%, and calcite 5%; the weight percentage composition of the transparent glaze 2 in step 5 is: Yingkou feldspar 45%, Sanbaopeng porcelain stone 9%, Donghai quartz 13%, Guangfeng talc 12%, zinc oxide 6%, and calcite 15%.

[0013] The ceramic pigment in step 4 is composed of a flux and a colorant in a ratio of 70-85%:15-30%. The painted decoration in step 4 is a single ceramic pigment decoration or a composite decoration of multiple ceramic pigments.

[0014] The flux is composed of 13% Sanbaopeng porcelain stone, 55% Yingkou feldspar, 3% Xingzi kaolin, 2.5% Guangfeng talc, 10% calcite, 6.5% zinc oxide, 5% zirconium silicate, and 5% borax in weight percentage.

[0015] The pigment is one of chrome tin red, chrome antimony titanium yellow, cobalt aluminum blue and cobalt chrome green.

[0016] The fineness of the flux is controlled to be 250 mesh, and the sieve residue is 1%.

[0017] The fineness of the transparent glaze is controlled to be 180 mesh, the sieve residue is 1%, the thickness applied on the inner surface of the blank is 0.8mm, and the specific gravity is 1.50g / cm 3 The fineness of transparent glaze II is controlled to 200 mesh, the sieve residue is 1%, the thickness applied on the outer surface of the body is 0.5mm, and the specific gravity is 1.20g / cm 3 ;

[0018] The firing system of high-temperature glaze firing in step 5 is: room temperature to 350°C, firing time 2.5 hours, 350 to 1100°C, firing time 5 hours, 1100°C to maximum temperature, firing time 3 hours, and keeping at the maximum temperature for 1 hour.

[0019] The formulation and process of the colored exquisite porcelain body glaze of the present invention mainly solve the following technical problems:

[0020] First, the ceramic body has high plasticity through the control of raw material formula, which is convenient for processing large-sized exquisite holes. And the mullite crystal phase formed in the porcelain body after high-temperature firing makes the porcelain body have good strength and small shrinkage.

[0021] Secondly, the transparent glaze, through the control of raw material formula, particle size, glaze layer thickness and specific gravity, has a large high-temperature viscosity, high glaze surface strength, and a large thermal expansion coefficient, so that it can provide strength support for the body during high-temperature firing, and can have a good mutual blend with ceramic pigments. After cooling, it can maintain the transparency of the exquisite eye and make the exquisite hole surface maintain the set decorative effect;

[0022] Third, transparent glaze II has greater high-temperature fluidity, a larger thermal expansion coefficient, and better glaze elasticity through the control of raw material formula, particle size, glaze layer thickness and specific gravity, so that it can provide ceramic pigments with better gloss and color saturation after high-temperature firing;

[0023] Fourth, the flux, through the control of raw material formula and particle size, makes the pigment have better gloss, smaller thermal expansion coefficient, smaller surface tension, and forms zirconium silicate crystal phase in the pigment after high temperature firing, which can provide better decorative effect for painting;

[0024] Fifth, through the formula of transparent glaze one, transparent glaze two, flux raw materials and the high-temperature glaze firing system in step five, the thermal expansion coefficient and melting performance of the ceramic pigment can be coordinated with those of transparent glaze one and transparent glaze two to obtain a smooth glaze effect.

[0025] Sixth, the sandblasting jet process is used to perforate the blank. The edges of the exquisite holes made by this technology are clear, neat, and versatile. It can flexibly realize various complex patterns of special-shaped holes, overcoming the shortcomings of the exquisite eyes such as unevenness, rough edges, and unevenness.

[0026] Seventh, by controlling the ratio of flux and colorant in ceramic pigments, the hue and color saturation of each pigment can be adjusted.

[0027] The present invention obtains colorful Linglong porcelain by designing a new body glaze formula and preparation process, which not only greatly improves the quality of Jingdezhen Linglong porcelain, but also breaks through the decorative effect of traditional Linglong porcelain. In addition, most of the raw materials used in the present invention are natural mineral raw materials, which are not only abundant in source and low in price, but also the painted pigments are located in the glaze after high-temperature firing, which is green and environmentally friendly, and therefore has a broad market space.
