Problems solved by technology

[0003] In recent years, the domestic waste incineration power generation industry has developed rapidly, and the amount of waste incineration bottom ash produced has also increased sharply. At present, this part of bottom ash is generally used directly for landfill, which not only occupies land resources, but also causes certain pollution to the environment.

Embodiment 1

[0019] (1) Prepare the panel: Pour 50% of the bottom ash, 20% of the ground sand and 15% of the lime in the mixer into the mixer and mix evenly, then add 15% of the water and continue to stir until Dry hard slurry, inject the slurry into the prepared panel mold, and then place a certain amount of steel mesh. After three rolls, the bulk density will reach 1900kg / m 3 , and then sent to the autoclave for 8 hours, the temperature and pressure of the water vapor in the autoclave were 200 ° C, 1.6 MPa, and the temperature was naturally cooled for 2 hours after leaving the autoclave. After demoulding, three thicknesses of 6mm, 8mm, and 10mm can be obtained panel.

[0020] (2) Preparation of wall panels: First, fix the two prepared panels on both sides of the wall panel mold according to the design requirements. In addition, by mass percentage, 40% of the bottom ash after incineration of domestic waste for power generation, 10% of lime, 20% of ground sand, 10% of cement, 2% of gypsum...

Embodiment 2

[0022] (1) Preparation of panels: Pour 65% of the bottom ash, 15% of finely ground sand and 5% of lime by mass percentage into the mixer and mix evenly, then add 15% of water and continue to stir until dry For hard slurry, inject the slurry into the prepared panel mold, and then place a certain amount of steel mesh. After three rolls, the bulk density will reach 2200kg / m 3 , and then sent to the autoclave for 8 hours, the temperature and pressure of the water vapor in the autoclave were 184 ° C, 1.2 MPa, and the temperature was naturally cooled for 2 hours after leaving the autoclave. After demoulding, three thicknesses of 6mm, 8mm, and 10mm can be obtained. panel.

[0023] (2) Preparation of wall panels: First, fix the two prepared panels on both sides of the wall panel mold according to the design requirements. In addition, by mass percentage, 30% of the bottom ash after incineration of domestic waste for power generation, 15% of lime, 15% of ground sand, 15% of cement, 4% ...

Abstract

The invention discloses a preparation method of a double-faced compound warm-keeping and energy-saving wallboard. The method comprises the following steps of mixing and stirring 50-70% of bottom ash of household garbage after the household garbage is burnt to generate electricity, 5-20% of milling fine sand, 5-15% of lime and 5-20% of water by mass percentage, obtaining hard slurry, injecting the hard slurry into a panel mold, placing a corresponding wire mesh, conducting three rolling procedures, steaming by high pressure, cooling, demolding, obtaining a panel, fixing the prepared panel on the two sides of a mold, mixing and uniformly stirring 30-50% of the bottom ash of the household garbage after the household garbage is burnt to generate the electricity, 10-20% of the lime, 10-25% of the milling fine sand, 10-20% of cement, 2-4% of plaster, 0.01-0.06% of aluminum powder and 5-20% of the water by mass percentage, obtaining slurry, injecting the slurry into a wallboard mold, stewing, steaming by the high pressure, cooling, demolding, and obtaining the wallboard.

Description

Technical field: [0001] The invention relates to the field of building materials, in particular to a preparation method of a double-sided composite thermal insulation and energy-saving wallboard. Background technique: [0002] With the development of the domestic construction industry and the improvement of national standards for building materials, traditional clay bricks have been basically eliminated in modern urban buildings, replaced by non-clay bricks (such as concrete hollow bricks, sintered shale bricks, lime sand bricks, etc.) and Various blocks (such as autoclaved aerated concrete blocks, gypsum blocks, sintered hollow blocks, etc.). However, they generally have the disadvantages of low construction efficiency, high labor cost and poor thermal insulation performance. The lightweight wallboard is a new type of building wall material, which has the characteristics of increasing the use area, reducing the weight of the wall, improving the use function, reducing the c...
