Embodiment Construction

[0015] A kind of corrosion-resistant aerated brick, it is made by the raw material of following weight kg:

[0016] Cement 12, diatomite 35, zinc powder 0.15, aluminum chloride 5, potassium hydroxide 0.4, caustic soda 0.6, calcium chloride 0.8, calcium hydroxide 0.1, coconut oil fatty acid diethanolamide 0.6, polypropylene fiber 0.2, fluorogypsum 19. Modified filler 15;

[0017] The modified filler is prepared from the following raw materials with a weight of kg: attapulgite 15, iron ore tailings 18, carbide slag 12, sodium acetate 2, diatomite 2, anhydrous sodium acetate 1.65, gelatin 0.4, glycerin Triacetate 1, isomeric alcohol polyoxyethylene ether 0.5, silane coupling agent KH792 2;

[0018] The preparation method of described modified filler is:

[0019] Take calcium carbide slag and iron ore tailings and mix them evenly, crush them, and burn the obtained powder in a flash kiln at 940°C for 5 seconds, then take it out and cool it, and mix it with attapulgite, gelatin, t...

Abstract

The invention discloses corrosion-resisting autoclaved aerated concrete block. The corrosion-resisting autoclaved aerated concrete block is prepared from the following materials in parts by weight: 10-20 parts of cement, 35-50 parts of diatomite, 0.15-0.2 part of zinc powder, 3-5 parts of aluminum chloride, 0.2-0.4 part of potassium hydroxide, 0.3-0.6 part of caustic soda, 0.5-0.8 part of calcium chloride, 0.1-0.2 part of calcium hydroxide, 0.4-0.8 part of coconut oil fatty acid glycollic diamide, 0.1-0.2 part of polypropylene fiber, 18-30 parts of fluorgypsum and 10-20 parts of modified filler. The corrosion-resisting autoclaved aerated concrete block disclosed by the invention is reasonable in dosing, good in thermal-insulation effect and light in weight; and meanwhile, the chemical acid and alkaline resistance is strong.

Description

technical field [0001] The invention relates to the field of aerated bricks, in particular to a corrosion-resistant aerated brick. Background technique [0002] Aerated bricks refer to aerated concrete blocks produced by high-temperature autoclaved equipment. The existing aerated bricks have a single variety and poor performance, which cannot meet the increasing market demand. Contents of the invention [0003] The object of the present invention is to provide a corrosion-resistant aerated brick. [0004] The above purpose is achieved through the following schemes: [0005] A corrosion-resistant aerated brick, characterized in that it is made from the following raw materials in parts by weight: [0006] Cement 10-20, diatomite 35-50, zinc powder 0.15-0.2, aluminum chloride 3-5, potassium hydroxide 0.2-0.4, caustic soda 0.3-0.6, calcium chloride 0.5-0.8, calcium hydroxide 0.1-0.2 , coconut oil fatty acid diethanolamide 0.4-0.8, polypropylene fiber 0.1-0.2, fluorine gypsu...
