Problems solved by technology

However, the soft porcelain clay in Dehua has a limited storage of raw materials, and the firing temperature of suet jade porcelain is as high as 1300-1400 ℃, and the firing time is longer, so the application of suet jade porcelain is mainly limited to daily porcelain and crafts. Art porcelain and other high-grade porcelain, but rarely used in architectural ceramic tiles

preparation example Construction

[0024] The preparation method of the sheep fat jade ceramic brick is illustrated as follows.

[0025] Prepare suet jade body. The mineral composition of the suet jade body includes: by mass percentage, translucent potassium feldspar: 42.0-50.0%, acicular translucent kaolin: 37.0-43.0%, and fused silica sand: 7.0-21.0%. As an example, the mineral composition of the suet jade body is: by mass percentage, translucent potassium feldspar: 46%, acicular translucent kaolin: 40%, and fused silica sand: 14%.

[0026] Translucent potassium feldspar is a mineral raw material mainly composed of potassium feldspar, containing a small amount of albite and free quartz. After being processed and purified by magnetic separation whitening equipment, the content of iron and titanium impurities in translucent potassium feldspar is reduced When it is less than 0.06 wt%, the purity of the translucent potassium feldspar can be improved, and the transmittance of the translucent potassium feldspar ca...

[0048] Step 1: Weigh the raw materials according to the mineral composition of the sheep fat jade body, and prepare the green body powder. The mineral composition of the suet jade body includes: by mass percentage, translucent potassium feldspar: 46%, acicular translucent kaolin: 40%, and fused silica: 14%. The chemical composition of the suet jade body includes: by mass percentage, SiO 2 : 64.09%, Al 2 o 3 : 22.38%, Fe 2 o 3 : 0.12%, TiO 2 : 0.05%, CaO: 0.51%, MgO: 0.16%, K 2 O: 4.62%, Na 2 O: 2.36%, loss on ignition: 5.57%.

[0049] Step 2: pressing the green body powder into a green body, and drying the green body. The drying time is 15-30 minutes, and the moisture content of the dried blank is controlled within 0.5 wt%.

[0050] Step 3: After the suet jade body is dried at high temperature, print the design pattern with an inkjet machine.

[0051] Step 4: Prepare suet jade protective glaze. The mineral composition of the suet jade protective glaze includes: by m...

[0057] Step 1: Weigh the raw materials according to the mineral composition of the sheep fat jade body, and prepare the green body powder. The mineral composition of the suet jade body includes: by mass percentage, 50% of translucent potassium feldspar, 43% of acicular translucent kaolin, and 7% of fused quartz. The chemical composition of the suet jade body includes: by mass percentage, SiO 2 : 61.29%, Al 2 o 3 : 24.13%, Fe 2 o 3 : 0.13%, TiO 2 : 0.05%, CaO: 0.56%, MgO: 0.17%, K 2 O: 5.10%, Na 2 O: 2.48%, loss on ignition: 5.96%.

[0058] Step 2: pressing the green body powder into a green body, and drying the green body. The drying time is 15-30 minutes, and the moisture content of the dried blank is controlled within 0.5 wt%.

[0059] Step 3: After the suet jade body is dried at high temperature, print the design pattern with an inkjet machine.

[0060] Step 4: Prepare suet jade protective glaze. The mineral composition of the suet jade protective glaze includes:...

Abstract

The invention discloses a mutton fat jade ceramic tile and a preparation method thereof. The preparation method comprises the following steps that a mutton fat jade green body is prepared, and mineralcompositions of the mutton fat jade green body comprise, by mass, 42.0%-50.0% of light-transmitting potassium feldspar, 37.0%-43.0% of acicular light-transmitting kaolin and 7.0%-21.0% of fused quartz sand; a design pattern is printed on the mutton fat jade green body in an ink-jet mode; and a mutton fat jade protective glaze is applied to the mutton fat jade green body subjected to ink-jet printing of the designed pattern, and firing is conducted to obtain the mutton fat jade ceramic tile. The mineral composition of the mutton fat jade protective glaze includes the following components in percentage by mass: 35.0 to 45.0 percent of light-transmitting potassium feldspar, 20.0 to 30.0 percent of acicular light-transmitting kaolin, 12.0 to 18.0 percent of fused quartz, 4.0 to 6.0 percent ofcorundum, 6.0 to 8.0 percent of barium carbonate and 1.0 to 3.0 percent of zinc oxide.

Description

technical field [0001] The invention relates to a ceramic brick comprising a suet jade body, an inkjet printing pattern and a suet jade protective glaze and a preparation method thereof, belonging to the technical field of ceramic brick production and manufacture. Background technique [0002] Suet jade porcelain is a kind of matte porcelain that flourished in the Tang Dynasty and originated in Dehua. At that time, Dehua's neighbors were rich in soft china clay with iron content, low titanium content, and high potassium content. The utensils made of this soft china clay were moist, delicate and soft, and had a greasy luster on the surface. Under the irradiation, it is translucent lard-like, with faint red or milky white color, so it is named suet jade porcelain, also known as "suet white jade". Suet jade porcelain fired at high temperature has a Mohs hardness of 6-6.5 and has high wear resistance. However, the soft porcelain clay in Dehua has a limited storage of raw mater...
