Aerated concrete block with low heat conductivity coefficient and preparation method thereof
The invention discloses an aerated concrete block with low heat conductivity coefficient and a preparation method thereof. The aerated concrete block is prepared from the following raw materials in parts by weight: 44-66 parts of olivine, 28-42 parts of expanded perlite, 16-22 parts of white cement, 12-18 parts of sepiolite fabric, 10-15 parts of honeycomb cinder, 2.5-4.5 parts of anhydrous sodium sulfate, 8-14 parts of polyphenyl granules, 5-10 parts of hollow glass micro powder, 4-8 parts of aluminum silicate fiber, 0.5-1 part of sodium fluosilicate, 4-6 parts of polyvinyl acetate, 2-4 parts of hydroxypropyl oxidized starch sodium succinate, 2-3 parts of sulfonated acetone-formaldehyde condensate, 1-2 parts of tartaric acid and 0.9-1.7 parts of modified aluminum powder. The aerated concrete block disclosed by the invention has the advantages of low heat conductivity coefficient, good heat insulating property, high strength, crack resistance, seepage resistance, acid-base erosion resistance, high-temperature resistance, long service life and obvious effects of energy conservation and consumption reduction and brings important economic and social benefits.
