Patent CN 104478419 A discloses a method for preparing high-white light-transmitting ceramic tiles, using natural quartz and fused silica as the main body, adding frit as a flux, and using high-plasticity bentonite as a binder for semi-dry pressing molding, but the quartz particles are in the During the high-temperature melting process, it is difficult to be dissolved by the liquid phase. The addition of more than 50% of the quartz material makes more quartz undissolved in the liquid phase, thereby forming cristobalite. The volume change caused by the phase change is likely to cause the body to burst. The fused silica This phenomenon is exacerbated by adding

Embodiment 1

[0026] An embodiment of the high-white light-transmitting marble tile blank of the present invention, the raw materials used in the high-white light-transmitting marble tile blank described in this embodiment are composed of: quartz: 37wt%; potassium feldspar: 8wt%; albite feldspar : 6wt%; low-temperature frit: 30wt%; high-temperature frit: 9wt%; Sodium tripolyphosphate, the chemical composition of each raw material is shown in Table 1, wherein, the particle size range of the low-temperature frit is 2-3 mm, and the initial melting point is 804 ° C; the particle size range of the high-temperature frit is 0.25-0.3 mm, The initial melting point is 1201°C:

[0029] Weigh each raw material according to the above mass percentage and put it into a ball mill tank, add ball stones and water, and then carry out ball milling. The specific ball milling process parameters are shown in Table 2. The ball-milled s...

Embodiment 2

[0073] Example 2 is fine-tuned on the basis of Example 1, the amount of plastic clay added is kept at 10wt%, and the flux and high-temperature skeleton are replaced. The specific test plan and the performance parameters of the green body are shown in Table 16 and Table 17 respectively. .

[0077] Table 17 The performance parameters of embodiment 2 series test green bodies after firing

[0078]

[0079] Comparing the tests 2-1 to 2-4, the amount of quartz added is more than 37wt% to ensure that the green body has a suitable melting point. This is the result of fine-tuning other raw materials in the formula of Example 1. Compromise and optimization results of various performance parameters; the reduction of high-temperature frit will lead to a decrease in incident light transmittance, indicating that the effect of frit on light transmission is much greater than that of the glass phase forme...

Embodiment 3

[0082] An embodiment of the high-white light-transmitting marble tile blank of the present invention, the raw materials used in the high-white light-transmitting marble tile blank described in this embodiment are composed of: quartz: 25wt%; potassium feldspar: 10wt%; albite feldspar : 10wt%; low-temperature frit: 15wt%; high-temperature frit: 20wt%; plastic clay: 20wt%, and add additional 0.3wt% green body reinforcement, 0.3wt% sodium carboxymethylcellulose, 1wt% Sodium tripolyphosphate, 0.5wt% dispersant, its specific preparation method and performance research are the same as in Example 1, and will not be repeated here.

Abstract

The invention discloses a high-whiteness transparent marble tile blank material, and a preparation method thereof. The high-whiteness transparent marble tile blank material comprises following components: 25 to 40wt% of quartz, 5 to 10wt% of potash feldspar, 5 to 10wt% of albite, 25 to 45wt% of frit, and 10 to 20wt% of plastic clay. The high-whiteness transparent marble tile blank material possesses excellent moulding performance, high dry blank strength, and excellent blank glaze adaptability, can be used in production of transparent whole body marble tiles. The prepared high-whiteness transparent marble tile blank material is extremely high in whiteness, so that the influences on pigment color development are low; blank body 400 DEG C cubical expansion coefficient is controlled to be 215*10<-7> to 220*10<-7>, the adaptability of the blank body with glaze is excellent.

Description

technical field [0001] The invention relates to the field of ceramic materials, in particular to a high-white light-transmitting marble tile blank and a preparation method thereof. Background technique [0002] Large-size light-transmitting stone is an excellent interior decoration material. The translucent natural stone is thinned to 4-6mm, or even 2mm ultra-thin stone slabs. When the light shines through the light-transmitting stone, it can fully express It shows the natural beauty of stone and has great artistic appreciation value. Due to the high price of natural stone, there are also relatively cheap artificial stones on the market. The artificial stone is made of translucent stone powder, resin and pigment through mold synthesis. However, artificial stone is easy to yellow, scratch, and age, and it is not easy to use for a long time. Based on the above background, marble tiles with light transmission properties have certain market potential. [0003] The traditiona...
