AI Technical Summary

Problems solved by technology

Tiles are used in many places. When used as facing bricks, the facing bricks are often required to have good air permeability. However, many tiles have poor air permeability, which causes water droplets on the surface of the bricks to condense under rainy or humid weather, which affects the use effect.
[0003] A large number of ceramic products are produced in our country every year, and a large number of defective products are often produced in the production process. Now the defective treatment method is directly discarded, which causes a waste of resources. Although waste ceramics are directly used for reprocessing ceramics, it is theoretically feasible. , however, the strength of the ceramics made of recycled waste ceramics is not enough, and it is prone to cracking and other phenomena, and the yield is not high

Embodiment 1

[0030] A highly air-permeable face brick made from the following raw materials by weight: 216 parts of kaolin, 48 parts of waste ceramics, 42 parts of modified fly ash, 23 parts of diatomite, 18 parts of glass fiber, and 3 parts of nanocomposites;

[0031] The modified fly ash is prepared using the following method:

[0032] (1) Crush the fly ash, soak it in an acid-base buffer solution for 20-30 minutes, stir continuously during the soaking process, then rinse it with clean water and dry it;

[0033] (2) Treat the fly ash processed in step (1) at 230-250°C for 8-10 minutes, then raise the temperature to 435°C for 16 minutes;

[0034] (3) Mix the fly ash processed in step (2) with calcium carbonate, polyurethane, and fatty alcohol polyoxyethylene ether sodium sulfate in a weight ratio of 45:1:2:0.2, and use a disperser to disperse for 25 minutes. Then heat-preserve at 185° C. for 5-8 minutes, and then lower to room temperature to obtain a mixture;

[0035] (4) Grinding the m...

Embodiment 2

[0050] A highly air-permeable face brick made from the following raw materials by weight: 218 parts of kaolin, 50 parts of waste ceramics, 42 parts of modified fly ash, 24 parts of diatomite, 18 parts of glass fiber, and 3.6 parts of nanocomposites;

[0051] The modified fly ash is prepared using the following method:

Abstract

The invention relates to a high air permeability face brick and a preparation method thereof. The face brick is prepared from the following raw materials by weight: 210-220 parts of kaolin, 45-50 parts of waste ceramics, 40-45 parts of modified fly ash, 22-25 parts of diatomite, 15-20 parts of glass fiber and 2-4 parts of nanocomposites. The prepared face brick has low cost, high yield and betterstrength and air permeability.

Description

technical field [0001] The application belongs to the field of new building materials, and in particular relates to a highly air-permeable face brick and a preparation method thereof. Background technique [0002] Ceramic tiles are refractory metal oxides and semi-metal oxides, which are formed by grinding, mixing, pressing, glazing, and sintering. A kind of acid and alkali resistant porcelain or stone, construction or decoration materials, called for tiles. Its raw materials are mostly mixed with clay, quartz sand and so on. Ceramic tiles are used in many places. When used as facing bricks, the facing bricks are often required to have good air permeability. However, many tiles have poor air permeability, which causes water droplets on the surface of the bricks to condense under rainy or humid weather, affecting the use effect. [0003] A large number of ceramic products are produced in our country every year, and a large number of defective products are often produced in ...
