Abstract

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.

Description

technical field [0001] The invention relates to a fireproof and flame retardant aerated block and a preparation method thereof, belonging to the field of building materials. Background technique [0002] Aerated blocks are made of siliceous materials (sand, fly ash and silicon-containing tailings, etc.) and calcareous materials (lime, cement, etc.) Pores are formed by chemical reactions, and porous silicate products are made through casting molding, pre-curing cutting, autoclaving curing and other processes. Aerated blocks have the characteristics of light weight, thermal insulation, good machinability, wide source of raw materials, high production efficiency, and low production energy consumption. They are widely used in load-bearing, enclosure, and filling of industrial and civil buildings. The general attention of various countries has become the preferred building material that many countries vigorously promote and develop. With the rapid development of my country's co...
