Summary of the invention
The purpose of this invention is to provide edible mushrooms chaff aerating brick and preparation method thereof, adopting the edible mushrooms chaff is raw material, can utilization of waste material, and simultaneously, employings dregs of rapeseed cake is raw material, can be used in remaining grease wherein, the hydrophobicity of increase gas brick.
Technical scheme of the present invention is as follows:
A kind of edible mushrooms chaff aerating brick is characterized in that its starting material by following weight part are processed into:
Edible mushrooms chaff 30-35, flyash 24-28, cement 15-20, lime 12-16, bamboo charcoal powder 3-5, oil foot 3-5, gypsum 12-18, aluminium powder 1-2, sodium dibutyl naphthalene sulfonate 1-2, wilkinite 16-19, lignocellulose 3-4, chitosan 2-3, Starso 3-5, potter's clay 8-10, dregs of rapeseed cake 2-3, ammonium persulphate 1-2, water are an amount of.
The preparation method of described a kind of edible mushrooms chaff aerating brick is characterized in that, may further comprise the steps:
(1), edible mushrooms chaff, wilkinite, oil foot are joined in the suitable quantity of water, be heated to 80-90 ℃, stirred 6-10 minute, add Starso, ammonium persulphate then, stirred 30-40 minute, then, add chitosan again and stirred 20-30 minute, become the mud shape;
(2) cement, flyash, lime are mixed, join in the suitable quantity of water, stirred 8-10 minute, add other raw materials such as mud, bamboo charcoal powder, aluminium powder potter's clay of step (1) gained again, stirred 10-15 minute, obtaining water content is the 35-40% slurry;
(3) slurry that stirs is injected mould;
(4) put into the chamber of resting then 45-50 ℃ of sealing insulation, rested time 1.5-2 hour;
(5) fragment of brick is put into carried out steam press maintenance 6-8 hour in the high pressure autoclave, steam-cured temperature is 200-215 ℃, steam-cured pressure 7-10 MPa;
(6) fragment of brick in the autoclave is removed pressure, lowered the temperature, goes out still.
Beneficial effect of the present invention:
The air-entrained concrete building block that the present invention produces, wherein adopt the oil foot composition, through the initiator modification, increased the hydrophobicity of building block, improved its infiltration ability greatly, building block of the present invention body of wall outside the residential quarter uses, last more than 3 years, do not find the wall leakage phenomenon, and adopt traditional air-entrained concrete building block that all have resident family infiltration to occur annual spring.Adopting rapeseed meal among the present invention is raw material, has increased the hydrophobicity of brick, improves anti-seepage effect, and simultaneously, adopting the edible mushrooms chaff is raw material, can utilization of waste material.
The air-entrained concrete building block that the present invention produces has advantages such as ultimate compression strength height, light weight, sound insulation, heat insulation, good heat preservation performance, anti-freezing property and contraction thereof be little, has solved traditional air-entrained concrete building block intensity defective low, easy to crack.
Embodiment
A kind of edible mushrooms chaff aerating brick, its starting material by following weight part (kilogram) are processed into:
Edible mushrooms chaff 30, flyash 28, cement 15, lime 16, bamboo charcoal powder 3, oil foot 5, gypsum 12, aluminium powder, sodium dibutyl naphthalene sulfonate 1, wilkinite 16, lignocellulose 4, chitosan 3, Starso 3, potter's clay 8, dregs of rapeseed cake 2, ammonium persulphate 2, water are an amount of.
The preparation method of described a kind of edible mushrooms chaff aerating brick may further comprise the steps:
(1), edible mushrooms chaff, wilkinite, oil foot are joined in the suitable quantity of water, be heated to 80-90 ℃, stirred 6-10 minute, add Starso, ammonium persulphate then, stirred 30-40 minute, then, add chitosan again and stirred 20-30 minute, become the mud shape;
(2) cement, flyash, lime are mixed, join in the suitable quantity of water, stirred 8-10 minute, add other raw materials such as mud, bamboo charcoal powder, aluminium powder potter's clay of step (1) gained again, stirred 10-15 minute, obtaining water content is the 35-40% slurry;
(3) slurry that stirs is injected mould;
(4) put into the chamber of resting then 45-50 ℃ of sealing insulation, rested time 1.5-2 hour;
(5) fragment of brick is put into carried out steam press maintenance 6-8 hour in the high pressure autoclave, steam-cured temperature is 200-215 ℃, steam-cured pressure 7-10 MPa;
(6) fragment of brick in the autoclave is removed pressure, lowered the temperature, goes out still.
The cubes that the hollow brick that the present invention is produced cuts into 100mm * 100mm * 100mm carries out Performance Detection, and detected result is as follows: ultimate compression strength 4.51Mpa, shrinkage value 0.67mm/m, frost resistance loss of strength 18%.
