[0017] The second step is to prepare the insulation sandwich layer, and stir 80kg of ordinary Portland cement with a strength grade of 42.5, 20kg of river sand of 50-70 mesh, 1.2kg of calcium stearate, and 3kg ...

Embodiment 2

[0021] The first step is to prepare the surface layer material, add 23.5kg of magnesium chloride to 100kg of water and stir evenly to prepare brine with a concentration of 23.5, add 0.3kg of trisodium phosphate, 0.6kg of phosphoric acid, 0.3kg of NNO diffusing agent, 0.5kg of isocyanate resin, 1.3kg of ferrous sulfate was stirred evenly to form the first mixture; 85kg of magnesia, 15kg of fly ash, and 0.2kg of polypropylene bundled monofilament fibers with a length of 10 to 20 mm were added to the 100kg of the first mixture and stirred evenly to form the second mixture;

[0022] The second step is to prepare the insulation sandwich layer. Stir 90kg of ordinary Portland cement with a strength grade of 42.5, 10kg of 50-70 mesh river sand, 1kg of calcium stearate, and 2.8kg of foam stabilizing enhancer to form a third mixture; 50kg of water with a temperature of 40°C is mixed with the third mixture, and stirred uniformly to form the fourth mixture; 4.5kg of hydrogen peroxide with ...

Embodiment 3

[0026] The first step is to prepare the surface layer material, add 23.5kg of magnesium chloride to 100kg of water and stir evenly to prepare brine with a concentration of 23.5, add 0.3kg of trisodium phosphate, 0.6kg of phosphoric acid, 0.3kg of NNO diffusing agent, 0.5kg of isocyanate resin, 1.3kg of ferrous sulfate was stirred evenly to form the first mixture; 85kg of magnesia, 15kg of fly ash, and 0.2kg of polypropylene bundled monofilament fibers with a length of 10 to 20 mm were added to the 100kg of the first mixture and stirred evenly to form the second mixture;

[0027] The second step is to prepare the insulation sandwich layer. Stir 100kg of ordinary Portland cement with a strength grade of 42.5, 0kg of 50-70 mesh river sand, 0.8kg of calcium stearate, and 2.4kg of foam stabilizing enhancer to form a third mixture; Mix 55kg of water at a temperature of 40°C with the third mixture, and stir to form a fourth mixture; mix 5.2kg of hydrogen peroxide with a volume concent...

Abstract

The invention relates to a production method for a self-insulation composite lightweight wall block and aims at effectively solving the problems of complex production process, low strength, great possibility of dropping powder, high water absorption and the like of aerated concrete blocks. The method comprises the following steps: adding magnesium chloride into water to prepare brine, adding trisodium phosphate, phosphoric acid, a NNO dispersing agent, isocyanate resin and ferrous sulfate into the brine, and uniformly stirring; adding magnesium oxide, coal ash, polypropylene bunchy monofilament fibers into the brine, and uniformly stirring to prepare a surface material; uniformly mixing silicate cement with river sand, calcium stearate and a foam stabilizing enhancer, then sequentially adding water and hydrogen peroxide, uniformly mixing to obtain mixed materials, pouring the mixed materials into a mold for forming, demolding, maintaining, and cutting; pouring the surface material into the mold, paving the bottom of the mold with the material, putting an insulation sandwich layer on the surface material, then pouring the surface material again to pack the mold, compacting, screeding, demolding and maintaining to produce the self-insulation composite lightweight wall block. The self-insulation composite lightweight wall block is economical, practical, high in strength, good in heat preservation and sound insulation effect, incapable of dropping powder from the surface and simple in construction process and has the anti-dampening, anti-scumming, anti-aging and waterproof effects.

Description

technical field [0001] The invention relates to building materials, in particular to a production method of self-insulating composite lightweight wall blocks. Background technique [0002] In order to protect the soil, the country promulgated the prohibition of firing and using red bricks as early as 1997. In 2005, the General Office of the State Council issued the "Notice on Further Promoting Wall Material Innovation and Promotion of Energy-saving Buildings". The notice proposed that by the end of 2010, All cities are to ban the use of solid clay bricks. Therefore, looking for masonry materials to replace clay sintered bricks has become a top priority in the construction industry. A series of masonry materials such as lime-sand bricks, hollow masonry, and cement bricks are used in construction. Aerated concrete blocks are widely used in buildings because of their light weight, heat preservation, sound absorption, and earthquake resistance, but they also have disadvantages...
