preparation example Construction

[0058] The preparation method of the light-transmitting brick comprises:

[0059] The raw material is ball milled to obtain a blank, and then the blank is pressed to obtain an adobe;

[0060] The adobe is sent to a kiln for firing after pretreatment, and then the product is obtained through posttreatment.

[0061] Preferably, before carrying out described ball milling, also include:

[0062] Stir-frying after mixing the raw materials, and then rapidly cooling;

[0063] The frying temperature is 200-400°C, and the rapid cooling refers to reducing the frying material to 20-25°C within 1-2 minutes;

[0064] Preferably, the particle size of the blank is less than or equal to 250 mesh.

[0065] The purpose of frying and rapid cooling is to enhance the plasticity of raw materials and reduce the deformation rate of later high-temperature firing.

[0066] Optionally, the frying temperature may be any value between 200°C, 250°C, 300°C, 350°C, 400°C and 200-400°C.

Embodiment 1

[0079] Prepare ingredients:

[0080] 5kg of quartz, 10kg of kaolin, 25kg of feldspar, 6kg of burnt talc, 4kg of pyrophyllite, 15kg of terrazzo nepheline, 5kg of low-temperature sand, 25kg of frit and 5kg of bone meal.

[0081] Wherein, the mass ratio of potassium feldspar and albite in feldspar is 1:1.

[0082] It should be noted that the chemical composition of the frit used in this embodiment includes: 58% silicon dioxide, 15% aluminum oxide, 0.2% iron oxide, 25% calcium oxide, 0.9% magnesium oxide, and 0.1% potassium oxide. %, sodium oxide 0.1% and a small amount of impurities.

[0083] Add water to the above raw materials, pass through a 250-mesh sieve to obtain a blank, and then press the blank under the condition of 100MPa to obtain a brick; grind the brick, inkjet and glaze, then send it to a kiln for firing, and then polish it to obtain a product; The firing includes the first firing, the second firing and the third firing; the temperature of the first firing is 300°...

Embodiment 2

[0086] Prepare ingredients:

[0087] 6kg of quartz, 12kg of kaolin, 21kg of feldspar, 7kg of burnt talc, 1kg of pyrophyllite, 17kg of terrazzo nepheline, 7kg of low-temperature sand, 28kg of frit and 1kg of bone meal.

[0088] Wherein, the mass ratio of potassium feldspar and albite in feldspar is 1:2.

[0089] It should be noted that the chemical composition of the medium-temperature frit used in this example includes: 59.44% silicon dioxide, 14.23% aluminum oxide, 0.45% iron oxide, 23.56% calcium oxide, 1.07% magnesium oxide, potassium oxide 0.46%, sodium oxide 0.31% and a small amount of impurities.

[0090] After mixing the raw materials, fry them at 200°C, and then lower the fried materials to 20°C within 1 minute. Add water to the above-mentioned fried raw materials, pass through a 250-mesh sieve after ball milling to obtain a blank, and then press the blank under the condition of 150MPa to obtain a brick; after the brick is ground, inkjet and glazed, it is sent into a...

Abstract

The invention provides a light-transmitting brick and a preparation method thereof, and relates to the field of ceramics. The light-transmitting brick is prepared from the following raw materials in percentage by mass: 5 to 8 percent of quartz, 10 to 30 percent of kaolin, 15 to 25 percent of feldspar, 6 to 8 percent of calcined talc, 1 to 5 percent of pyrophyllite, 15 to 25 percent of water milled nepheline, 5 to 10 percent of low-temperature sand and 30 to 45 percent of a calcium raw material, wherein the calcium raw material is bone meal or frit. The preparation method of the light-transmitting brick comprises the steps of carrying out ball milling on the raw materials to obtain a blank, and then carrying out compression molding on the blank to obtain a green brick; and carrying out pretreatment on the green brick, then feeding the green brick into a kiln to be sintered, and then obtaining a product through aftertreatment. The light-transmitting brick provided by the invention is high in light transmittance and high in strength.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a light-transmitting brick and a preparation method thereof. Background technique [0002] As a common building material, ceramic tiles play a very important role in beautifying decoration. With the improvement of people's quality of life, people have more and more functional requirements for ceramic tiles. Due to the reasons of raw materials and processing technology, conventional ceramic tiles often have many impurities and pores, which absorb and scatter light, so they do not have light transmission, and cannot meet people's requirements for ceramic tiles in terms of transparency and visual changes. need. [0003] At present, there are also manufacturers developing light-transmitting bricks, and their light-transmitting properties also have good performance, but there are often problems such as easy deformation of bricks, low firing rate, and low product strength. [0004] Therefore...
