Non-porous ivory white porcelain plastic and preparation method thereof

Abstract

The invention provides a non-porous ivory white porcelain plastic and a preparation method thereof. The non-porous ivory white porcelain plastic comprises the following materials in percentage by weight, 31%-49% of kaolin, 12%-18% of porcelain powder, 6%-10% of quartz, 3%-6% of limestone, 9.5%-14% of clay, 5%-9% of feldspar, 3.5%-7% of calcium oxide, 1.5%-5% of magnesium oxide, 4.5%-9% of silicondioxide, 2%-7% of aluminum oxide and 1%-3% of ferric oxide. Beneficial effects are as following, kaolin, quartz, feldspar, clay and porcelain powder are used as raw materials of a green body; all theraw materials are fully mixed, the middle of the porcelain plastic body is solid and free of pores, the hardness, abrasion resistance and water resistance of fired porcelain plastic products are improved by improving the density of the fired porcelain plastic products, the whole body is porcelainized and burnt through, the surface is free of cracks, spots and pores, the surface is smooth and bright, and very high collection value and economic value are achieved.

Description

technical field [0001] The invention relates to a non-porous ivory white porcelain plastic and a preparation method thereof, belonging to the field of porcelain plastic processing. Background technique [0002] At present, porcelain sculpture has a unique style and is the most successful porcelain product. After the end of the Ming Dynasty, various types of Avalokitesvara statues, statues of Buddhist and Taoist figures, and non-religious figures began to be mass-produced and sold overseas. The thickest porcelain body is solid pile molding. Once it is exposed to high temperature in the kiln, it will "crack when it is thick". The shrinkage speed is different, the temperature is from the outside to the inside, the outer layer is heated quickly, the temperature is relatively high, and the shrinkage is fast, the inner heat is slightly slower, the temperature is relatively low, and the shrinkage is slower. Therefore, the existing porcelain plastic works are all hollow structures,...

AI Technical Summary

Problems solved by technology

Therefore, the existing porcelain plastic works are all hollow structures, and the inside is hollow. However, the thickness between the inner wall and the outer wall of different parts of the porcelain plastic is different, and its mechanical properties are low and easy to break. Therefore, there is a need for a non-porous Ivory white porcelain plastic and its preparation method
