Fireproof flame-retardant aerocrete building block and preparation method thereof
The invention discloses a fireproof flame-retardant aerocrete building block and a preparation method thereof. The fireproof flame-retardant aerocrete building block is prepared from the following raw materials in parts by weight: 50-70 parts of potash feldspar, 16-22 parts of iron aluminate cement, 11-17 parts of calcium hypophosphite, 15-20 parts of boehmite, 10-15 parts of borax, 18-24 parts of sericite, 22-28 parts of chalk powder, 16-22 parts of coconut shell flour, 4-7 parts of polyethyleneimine, 2-4 parts of sodium wolframate, 1-2 parts of triethanolamine, 3-5 parts of konjaku flour, 1.5-2.5 parts of modified aluminum powder, 2.5-4.5 parts of sodium polystyrene sulfonate and 3-5 parts of calcium carbide powder. The aerocrete building block has excellent flame retardancy and high fire resistance, and the flame retardancy grade reaches Grade A; and the aerocrete building block has the advantages of high strength, favorable heat resistance, favorable thermal-insulation property, favorable sound-insulation effect, aging resistance, seepage resistance, crack resistance, earthquake resistance, corrosion resistance and the like.
