Problems solved by technology

[0002] As a new type of wall material, aerated brick is a low-energy, environmentally friendly new building material, which belongs to the building material promoted by the state. However, because ordinary aerated concrete bricks are made of cement, fly ash, quicklime, gypsum, etc., There are problems such as large drying shrinkage, low strength, water seepage, no corrosion resistance, poor heat insulation, and single source of materials. Therefore, further research on the technology of aerated concrete bricks is urgently needed to further meet the requirements of the market.

Embodiment Construction

[0017] An edible fungus chaff aerated brick, which is processed from the following raw materials in parts by weight (kg):

[0018] Edible mushroom bran 30, fly ash 28, cement 15, lime 16, bamboo charcoal powder 3, oil foot 5, gypsum 12, aluminum powder, sodium dibutyl naphthalene sulfonate 1, bentonite 16, lignocellulose 4, chitosan 3. Sodium metasilicate 3. Pottery clay 8. Rapeseed meal 2. Ammonium persulfate 2. Appropriate amount of water.

[0019] A method for preparing an edible fungus chaff aerated brick comprises the following steps:

[0020] (1) Add edible fungus bran, bentonite, and oil foot into an appropriate amount of water, heat to 80-90°C, stir for 6-10 minutes, then add sodium metasilicate and ammonium persulfate, stir for 30-40 minutes, then, Then add chitosan and stir for 20-30 minutes until it becomes muddy;

[0021] (2) Mix cement, fly ash and lime, add it to an appropriate amount of water, stir for 8-10 minutes, then add the mud, bamboo charcoal powder, al...

Abstract

The invention provides an edible fungus chaff aerated brick. The aerated brick is prepared from the raw materials comprising, by weight, 30-35 parts of edible fungus chaff, 24-28 parts of fly ash, 15-20 parts of cement, 12-16 parts of lime, 3-5 parts of bamboo charcoal powder, 3-5 parts of oil foot, 12-18 parts of gypsum, 1-2 parts of aluminium powder, 1-2 parts of nekal, 16-19 parts of bentonite, 3-4 parts of lignocellulose, 2-3 parts of chitosan, 3-5 parts of sodium metasilicate, 8-10 parts of argil, 2-3 parts of rapeseed meal, 1-2 parts of ammonium persulfate and moderate water. The method employs the rapeseed meal as a raw material and the hydrophobicity of the brick is raised and the seepage-proofing effect is improved. Edible fungus chaff is employed as a raw material and waste materials can be utilized.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an aerated brick and a preparation method thereof. Background technique [0002] As a new type of wall material, aerated brick is a low-energy, environmentally friendly new building material, which belongs to the building material promoted by the state. However, because ordinary aerated concrete bricks are made of cement, fly ash, quicklime, gypsum, etc., There are problems such as large drying shrinkage, low strength, water seepage, no corrosion resistance, poor heat insulation, and single source of materials. Therefore, further research on aerated concrete brick technology is urgently needed to further meet market requirements. Contents of the invention [0003] The object of the present invention is to provide edible fungus bran aerated bricks and its preparation method. Edible fungus bran is used as raw material, which can be used as waste. hydrophobicity. [0004] Techn...
