Problems solved by technology

[0003] The main raw materials of the existing imitation bluestone hemp panels prepared by using china clay tailings and fly ash are calcareous materials, siliceous materials and reinforcing fibers, and most of the raw materials are powdery, and the bonding strength between them is poor. The internal stress of the imitation blue stone hemp panel is relatively large, which leads to the easy cracking of the building materials prepared by the fiber cement board during use, which seriously affects the quality and service life of the building

Embodiment 1

[0027] The imitation bluestone hemp panel of this embodiment includes the following components: 30 parts of china clay tailings, 25 parts of fly ash, 15 parts of Portland cement, 2 parts of perlite, 10 parts of wood pulp fiber and 20 parts of carbide slag.

[0028] The method that present embodiment prepares imitation bluestone hemp panel is as follows:

[0029] (1) Preparation of wood pulp fibers: crush and grind waste kraft paper bags or waste cartons, cool at -20°C for 20 minutes, then grind and disperse to remove crude fibers, and then inject ammonia gas into the obtained slurry. Adjust the slurry pH to be 8, and then obtain the wood pulp fiber through beating;

[0030] (2) Preparation of slab slurry: Mix 30g of china clay tailings, 25g of fly ash, 15g of Portland cement, 2g of perlite, 10g of wood pulp fiber produced in step (1) and 20g of calcium carbide slag in proportion to make a mixture Slurry, then add water and continue to stir and mix evenly to obtain slab slurry...

Embodiment 2

[0035] The imitation bluestone hemp panel of this embodiment includes the following components: 25 parts of china clay tailings, 22 parts of fly ash, 10 parts of Portland cement, 3 parts of perlite, 15 parts of wood pulp fiber and 25 parts of carbide slag.

[0036] The method that present embodiment prepares imitation bluestone hemp panel is as follows:

[0037] (1) Preparation of wood pulp fibers: crush and grind waste kraft paper bags or waste cartons, cool at -15°C for 40 minutes, then grind and disperse to remove crude fibers, and then inject ammonia gas into the obtained slurry. Adjust the slurry pH to 8.5, and then obtain the wood pulp fiber through beating;

[0038] (2) Preparation of slab slurry: Mix 25g of china clay tailings, 22g of fly ash, 10g of Portland cement, 3g of perlite, 15g of wood pulp fiber produced in step (1) and 25g of calcium carbide slag in proportion to make a mixture Slurry, then add water and continue to stir and mix evenly to obtain slab slurry;...

Embodiment 3

[0043] The imitation bluestone hemp panel of this embodiment includes the following components: 35 parts of china clay tailings, 20 parts of fly ash, 20 parts of portland cement, 5 parts of perlite, 8 parts of wood pulp fiber and 22 parts of carbide slag.

[0044] The method that present embodiment prepares imitation bluestone hemp panel is as follows:

[0045] (1) Preparation of wood pulp fibers: crush and grind waste kraft paper bags or waste cartons, cool at -18°C for 30 minutes, then grind and disperse to remove crude fibers, and then inject ammonia gas into the obtained slurry. Adjust the slurry pH to 9, and then obtain the wood pulp fiber through beating;

[0046] (2) Preparation of slab slurry: Mix 35g of china clay tailings, 20g of fly ash, 20g of Portland cement, 5g of perlite, 8g of wood pulp fiber produced in step (1) and 22g of calcium carbide slag in proportion to make a mixture Slurry, then add water and continue to stir and mix evenly to obtain slab slurry;

Abstract

The invention provides an imitation bluestone hemp panel prepared by using china clay tailings and fly ash and a preparation method thereof. The imitation bluestone hemp panel comprises the following components: 25-35 parts of china clay tailings, 20-25 parts of fly ash, Portland cement 10~20 parts, wood pulp fiber 8~15 parts and carbide slag 20~25 parts. The imitation bluestone hemp panel provided by the present invention has fire protection grade A1, good moisture-proof effect, insect-proof and ant-proof, strength up to 22Mpa, load up to 8kN / ㎡, and good earthquake resistance. After the board is installed, it can be directly tiled, floored, carpeted, etc. It can replace gypsum board, wood board, marble, concrete floor, etc. It is widely used in indoor and outdoor boards, decorative materials and other fields. The imitation bluestone hemp panel provided by the invention makes full use of various waste resources, turns waste into treasure, effectively reduces environmental pollution, reduces waste of land resources, and has good social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a fire-proof board, in particular to a bluestone-like hemp board prepared by using china clay tailings and fly ash and a preparation method thereof. Background technique [0002] The imitation bluestone hemp panel using porcelain clay tailings and fly ash as the main raw materials is a kind of fiber cement board. Fiber cement board is a new type of low-density and high-strength building material, which is widely used because of its small deformation, fire resistance, and water resistance. In the field of housing construction, it is mainly used for suspended ceilings, ceilings, partition walls, exterior walls, ground laying and veneer panels. Because fiber cement board has the characteristics of fire resistance and high temperature resistance, it can be used as thermal insulation material in the flue, boiler and pipeline of power plants and chemical plants,...
