Problems solved by technology

[0003] Daily-use ceramics refer to ceramics for eating and drinking, that is, ceramic products such as plates, bowls, cups, and saucers. Daily-use porcelain has been loved and used by the masses for a long time; however, ceramic products also have defects. In terms of weight, its mechanical properties are also poor, and it is easy to be broken. These factors limit the use of ceramic products in some occasions and need further improvement.

preparation example Construction

[0036] A method for preparing low-temperature lightweight daily-use porcelain, comprising the following steps:

[0037] Step 1, respectively weighing, crushing, mixing, and wet ball milling to obtain mud according to the raw material composition of the green body;

[0038] Step 2, weighing, crushing, mixing and wet ball milling respectively according to the composition of the raw materials of the cosmetic soil layer to obtain the cosmetic soil slurry;

[0039] Step 3, respectively weighing, crushing, mixing, and wet ball milling to obtain glaze slurry according to the composition of the raw materials of the glaze layer;

[0040] Step 4: Make the mud made in Step 1 into a green body, and when the moisture content is lower than 10%, apply the make-up clay mud made in Step 2 on its surface, and send it into a kiln at 780-830°C Under the biscuit firing for 5-6h, after cooling, the biscuit is obtained;

[0041] Step five, applying the glaze slurry obtained in step three on the bi...

Abstract

The invention discloses low-temperature light domestic porcelain and a preparation method thereof. The domestic porcelain comprises a green body, and an engobe layer and an enamel layer which are sequentially coated on the green body from inside to outside, the green body is prepared from the following raw materials: potassium feldspar, illite, montmorillonite, Dehua quartz, bentonite, borax, pyrophyllite, diopside, calcium oxide and titanium oxide; the engobe is prepared from the following specific chemical components: 72.62 percent of SiO2, 12.16 percent of Al2O3, 3.76 percent of ZnO, 5.96 percent of CaO, 0.32 percent of SrO, 0.25 percent of ZrO2, 0.17 percent of La2O3 and 4.76 percent of MgO; the composition of the green body is limited, and the pyrophyllite and the diopside are matched with the borax, so that the heat resistance of the green body is improved, and the heat stability of the prepared domestic porcelain is further improved.

Description

technical field [0001] The invention belongs to the field of daily-use porcelain preparation, and in particular relates to a low-temperature light-weight daily-use porcelain and a preparation method thereof. Background technique [0002] The history of Chinese ceramics development is long. From the firing of the most primitive pottery in the early Neolithic Age to the invention of porcelain and its widespread application, technology and art are constantly improving; in the process of adapting to the needs of people's survival and life, the types of fired ceramics are increasing, and the styles are increasing. It is changing, and the internal quality is constantly improving. The handicraft manufacturing technology of ceramic ware contains rich scientific and artistic connotations, and its manifestations are mainly displayed through shape and decoration, texture and color. The conversion process of ceramic production from raw materials to finished utensils must be completed ...
