Embodiment 1

[0028] The embodiment of the present application provides a body of pottery sanitary ware. The raw materials of the body include: 10-40% by weight of southern black mud, 10-30% by weight of southern kaolin, and 10-30% by weight of southern pyrophyllite. The percentage is 5-20%, the weight percentage of quartz is 10-25%, the weight percentage of calcined kaolin is 10-30%, the weight percentage of waste porcelain powder is 0-15%, and the weight percentage of wollastonite is 0-20%. 15%, 0-8% by weight of dolomite, 0-10% by weight of talc, electrolyte.

[0029] Specifically, the main raw materials used in the green body of the present invention include southern black mud, southern kaolin, southern pyrophyllite, quartz, calcined kaolin, waste porcelain powder of our factory, wollastonite, dolomite, talc, electrolyte, etc. The physical and chemical properties of the raw materials used are shown in Table 1, Table 2, and Table 3.

Embodiment 2

[0063] The embodiment of the present application also provides a method for preparing the body of ceramic sanitary ware, which is used to prepare the body of ceramic sanitary ware according to claims 1-7, such as figure 1 As shown, the method includes:

[0064] Step 110: Weigh the raw materials according to the proportion, add appropriate amount of water and electrolyte, stir in the mixer, put into the ball mill and grind to the specified particle size. After sieving and removing iron, it is prepared into slurry for grouting;

[0065] Step 120: According to the performance requirements of the molding process, the concentration, temperature, fluidity, and slurry feeding speed of the ball-milled slurry are properly adjusted. After 3 days of aging, various samples are obtained by grouting;

[0066] Step 130: Using the grouting method, inject the mud into the plaster model or resin model of the desired product, and demould after a certain period of time;

[0067] Step 140: After...

Abstract

The invention provides an earthen sanitary ware blank and a preparation method thereof. A proper quantity of raw materials such as kaolin and quartz are introduced; the crystalline phase content of mullite, quartz and the like in the blank is controlled; the glass phase content of potassium oxide and sodium oxide is reduced; the high-temperature plastic deformation is reduced; the low deformationof earthen sanitary ceramics is realized. The thermal expansion coefficient of the blank at 200 to 300 DEG C is regulated, so that the thermal expansion coefficient of the blank is matched with the thermal expansion coefficient of glaze. The problem that the earthen sanitary ware blank cannot overcome shrinkage and great deformation is solved, so that the earthen sanitary ware does not use engobeand does not generate glaze checking; qualified products are produced according to an earthen sanitary ware production method.

Description

technical field [0001] The invention belongs to the technical field of ceramics, in particular to a body of ceramic sanitary ware and a preparation method thereof. Background technique [0002] With the improvement of people's life, people's requirements for bathroom space decoration design are getting higher and higher, the artistry and personalization are getting stronger and stronger, and higher requirements are put forward for the manufacture of bathroom products, especially for the quality of products. The large size and regularity put forward higher requirements. [0003] However, ceramic products also have its shortcomings. For example, the traditional ceramic sanitary ceramics have relatively coarse particles, so it is necessary to use make-up soil to cover the body to reduce glaze pinholes, but the use of make-up soil makes the production process complicated. , And it is easy to produce defects such as rolling glaze, and the product qualification rate is reduced. ...
