Embodiment 1

[0018] Mix 100g of cement, 35g of yellow sand, 22g of gypsum, 7g of polydimethylsiloxane, 4g of barium sulfate, 5g of coal ash powder, 120g of water and 3g of waterproofing agent to prepare a mixture M; add the mixture M to the molding In the mold, unburned brick body N is obtained by hot pressing; spray water on the surface of the unburned brick body, and then dry it naturally; place the unburned brick body after natural drying in an oven for drying (the drying temperature is 55°C , the drying time is 2h), and unburned bricks are obtained.

Embodiment 2

[0020] Mix 100g of cement, 45g of yellow sand, 26g of gypsum, 12g of polydimethylsiloxane, 6g of barium sulfate, 8g of coal ash powder, 140g of water and 5g of waterproofing agent to prepare a mixture M; add the mixture M to the molding In the mold, unburned brick body N is obtained by hot pressing; water is sprayed on the surface of the unburned brick body, and then naturally dried; the naturally dried unburned brick body is placed in an oven for drying (the drying temperature is 65°C , the drying time is 5h), and unburned bricks are obtained.

Embodiment 3

[0022] Mix 100g of cement, 40g of yellow sand, 24g of gypsum, 10g of polydimethylsiloxane, 5g of barium sulfate, 6g of coal ash powder, 130g of water and 4g of waterproofing agent to prepare a mixture M; add the mixture M to the molding In the mold, unburned brick body N is obtained by hot pressing; spray water on the surface of the unburned brick body, and then dry it naturally; place the unburned brick body after natural drying in an oven for drying (the drying temperature is 60°C , the drying time is 3h), and unburned bricks are obtained.

Abstract

The invention discloses a baking-free brick and a preparation method thereof, wherein the preparation method comprises the following steps of mixing cement, yellow sand, gypsum, polydimethylsiloxane, barium sulfate, fly ash, water and waterproof agents to prepare a mixed material M; adding the mixed material M into a shaping mold; obtaining a baking-free brick blank N through hot pressing; spraying water onto the surface of the baking-free brick blank body; then, performing natural draying; putting the naturally dried baking-free brick blank body into a baking oven to be dried; obtaining the baking-free brick. The problems that a conventional baking-free brick has weak weather resistance capability, and the cracking easily occurs after the long time use are solved.

Description

technical field [0001] The invention relates to the field of unburned bricks, in particular to an unburned brick and a preparation method thereof. Background technique [0002] Unburned brick is a new type of wall material manufactured by using fly ash, coal slag, coal gangue, tailings slag, chemical slag or natural sand, sea mud, etc. as the main raw materials without high-temperature calcination. Traditional non-fired bricks have weak weathering resistance and are prone to cracking after long-term use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a non-burning brick and its preparation method, which solves the problem that the traditional non-burning brick has weak weathering resistance and is easy to crack after long-term use. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a method for preparing unburned bricks, wherein the preparation metho...
