Problems solved by technology

[0006] The above-mentioned patent documents all use Longyan kaolin and potassium feldspar as the main raw materials in the tire material. Among them, the market price of Longyan kaolin and potassium feldspar is relatively high, which will increase the production cost, and several toughening materials in the blank are barren. Excessive content will directly affect the plasticity of the blank, which is not conducive to the molding of celadon, resulting in a low yield rate, which is not conducive to the conventional production of daily-use porcelain

Embodiment 1

[0049] A high plasticity strengthened Longquan celadon body, the blank includes the following components in terms of weight percentage: 35% of washed Baoxi porcelain clay, 27% of washed Huangshi Xuan porcelain clay, 25% of washed Badu porcelain clay, Al 2 o 3 Micropowder 15%, zirconia micropowder 1%.

[0050]The above-mentioned highly plastic reinforced Longquan celadon mud is used to prepare strengthened Longquan celadon, and the preparation method thereof comprises the following steps:

[0051] (a) The Baoxi porcelain clay, Huangshixuan porcelain clay and Badu porcelain clay which are unique to Longquan are crushed respectively and washed 4 times to minimize the infertile material components in such raw materials, and then dried in a drying room at 100°C to obtain Panning Baoxi porcelain clay, panning Huangshi Xuan porcelain clay, panning Badu porcelain clay;

[0052] (b) According to the preset ratio, mix the above blank components, then add water, and ball mill for 1 to ...

Embodiment 2

[0058] A high plasticity strengthened Longquan celadon body, the blank includes the following components in terms of weight percentage: 55% of washed Baoxi porcelain clay, 13% of washed Huangshi Xuan porcelain clay, 45% of washed Badu porcelain clay, Al 2 o 3 Micropowder 10%, zirconia micropowder 2%.

[0059] The above-mentioned high plasticity strengthened Longquan celadon body is prepared into high plasticity strengthened Longquan celadon, and the preparation method thereof comprises the following steps:

[0060] (a) Grind Baoxi porcelain clay, Huangshi Xuan porcelain clay and Badu porcelain clay respectively and wash them five times to minimize the barren material components in such raw materials, and dry them at a temperature of 100°C;

[0061] (b) Mix the components of the billet according to the preset ratio, then add water, and ball mill for 1 to 2 hours according to the material-ball-water ratio of 1:1:0.8, wherein the ball milling speed is 30r / min, after ball milling...

Embodiment 3

[0067] A high plasticity strengthened Longquan celadon body, the blank includes the following components in terms of weight percentage: 45% of washed Baoxi porcelain clay, 18% of washed Huangshi Xuan porcelain clay, 20% of washed Badu porcelain clay, Al 2 o 3 Micropowder 15%, zirconia micropowder 2%.

[0068] The above highly plastic reinforced Longquan celadon mud is used to prepare highly plastic reinforced Longquan celadon, and the preparation method is the same as that of Example 1.

[0069] The common Longquan celadon in the existing market is selected for comparison. The flexural strength of the common Longquan celadon in the existing market is 45-60Mpa, and the thermal stability is 160-20°C without cracking once exchanged with hot and cold water. However, the highly plastic reinforced Longquan celadon prepared in this example has high strength and thermal stability when fired in a high-temperature reducing atmosphere at 1280-1300 ° C. Its flexural strength can reach 11...

Abstract

The invention provides a high-plasticity reinforced longquan celadon ware and a preparing method thereof. A blank of the high-plasticity reinforced longquan celadon ware is prepared from, by weight, 35-55% of elutriated Baoxi porcelain clay, 13-27% of elutriated Huang Shixuan porcelain clay, 25-45% of elutriated Badu porcelain clay, 10-15% of Al2O3 micro powder and 1-2% of zirconium oxide micro powder. The reinforced longquan celadon ware has high strength and high thermal stability when sintered in a reducing atmosphere at the high temperature of 1280-1300 DEG C, the breaking strength of the reinforced longquan celadon ware can reach 90-130 MPa, the reinforced longquan celadon ware does not crack in 240-20 DEG C cold and hot water exchange on the thermal stability, the breaking and bending strength is improved by 100-120% compared with that of existing common longquan celadon ware, the thermal stability is improved by 50%, the product can be prevented from being damaged by small knocks in daily use, and the produced daily celadon product can meet the cleanness requirement of mechanical equipment. The components of the blank have high strength, have very high plasticity at the same time, can adapt to various forming methods such as manual forming, rolling forming, slip casting forming and the like in the ceramic industry field, and are high in applicability.

Description

technical field [0001] The invention belongs to the technical field of porcelain preparation, and in particular relates to a high-plasticity reinforced Longquan celadon and a preparation method thereof. Background technique [0002] Celadon is a kind of porcelain with cyan glaze on the surface. It is a treasure of Han ceramic firing technology. The color tone of celadon is mainly caused by a certain amount of iron oxide contained in the glaze, which is baked in a reducing flame atmosphere. However, some celadon porcelains are yellow or yellowish-brown due to the impure iron content and insufficient reducing atmosphere. [0003] Longquan City, Zhejiang Province is a famous capital of celadon in my country. It is rich in porcelain clay mineral resources, and the local area is rich in high-silicon and high-iron porcelain clay. Longquan celadon is a famous porcelain variety in my country, and it is also the only ceramic project in China that has been selected into the represent...
