Abstract
The invention discloses an air-added brick which is produced by modified straw ash and a method for processing the air-added brick. The air-added brick comprises the follow raw materials in part by weight: 45 to 55 parts of diatomaceous earth, 5 to 8 parts of cement, 10 to 15 parts of iron ore tailings, 5 to 10 parts of powdery carbon, 14 to 16 parts of quicklime, 4 to 5 parts of fire clay, 2 to 3 parts of alunite, 0.03 to 0.05 part of calcium bicarbonate, 5 to 10 parts of modified straw ash, 0.03 to 0.04 part of nekal, 0.01 to 0.02 part of aluminum powder and 0.3 to 0.5 part of sodium diacetate. By using the diatomaceous earth as an ingredient of the air-added brick, the cost is low, the usage amount is large, and the environment is protected; energy consumption is reduced; the raw materials are optimized by the modified straw ash, the prepared air-added brick has higher heat isolation performance and sound isolation performance compared with the conventional air-added brick; and meanwhile, by optimizing a formula and the raw materials, and the strength and the freezing resistance are obviously improved.
Description
Technical field
The present invention relates to building material field, specifically belong to aerated bricks and working method thereof that a kind of modified straw ash is produced.
Background technology
Aerated bricks is the aerated bricks building block of producing by autoclave at high temperature apparatus and process, adopt the brick product of other various explained hereafter that comprise steam pressure, aerated bricks is a kind of novel wall material, its unique distinction is that it is a kind of novel building walling of very light-duty heat insulating, and that this technology of China starts is more late, than abroad, totally fallen behind 40 years, but, the development of the aerated bricks industry of China is really very fast, and domestic aerated bricks technical matters level can reach international most advanced level now.
Aerated bricks sharpest edges economize the land resource exactly, need not waste a large amount of arable lands, and the source of its raw material very extensively, dust and sand, slag, flyash and coal gangue etc. are all the starting material of doing aerated bricks, and very superior of the performance characteristics of aerated bricks, have extraordinary can working ability and heat insulation and insulated capacity, and very strong of plasticity-, have extraordinary processing characteristics, the research of aerated bricks raw material and processing technology need further to improve.
Summary of the invention
The aerated bricks and the working method thereof that the object of the present invention is to provide a kind of modified straw ash to produce.
The present invention adopts following technical scheme to achieve these goals:
The aerated bricks that modified straw ash is produced, the weight part of its constitutive material is: diatomite 45-55, cement 5-8, iron ore tailings 10-15, powdered carbon 5-10, unslaked lime 14-16, fireclay 4-5, alunite 2-3, Calcium hydrogen carbonate 0.03-0.05, modified straw ash 5-10, sodium dibutyl naphthalene sulfonate 0.03-0.04, aluminium powder 0.01-0.02 and sodium Diacetate 0.3-0.5.
The working method of the aerated bricks that modified straw ash is produced, comprises the following steps:
(1) raw-material processing: starting material comprise diatomite, cement, iron ore tailings, powdered carbon, unslaked lime, fireclay and alunite; Be crushed to fineness and reach 180-200 order;
(2) stir: Xian Jiashui stirs separately, then mix and blend also adds other surplus stocks in raw material by weight;
(3) cast: the slurry that step (2) is stirred adds in stock mould, obtains brick idiosome;
(4) rest: the brick idiosome of step (3) is put into the chamber of resting, the chamber sealing thermal insulation 40-45 ℃ that rests, time 3-3.5 hour rests;
(5) cutting: the brick idiosome that step (4) is rested is put into and is processed into certain desired size on cutting machine;
(6) steam-cured: the green compact of above-mentioned steps (5), at 0.7-0.9Mpa vapor cure 15-18h, are obtained to aerated bricks finished product.
Described modified straw ash is that straw ash is admixed and is equivalent to the use epoxyoleic acid butyl ester of powder weight 1-2%, the calcium lignin sulphonate agitating of 1-2% is even, dries, and is ground into 150-200 order powder and obtains.
Beneficial effect of the present invention:
The present invention is by adopting diatomite as the composition of aerated bricks, and with low cost, consumption is large, has protected environment; Reduced energy consumption; Modified straw ash has been optimized starting material, and the aerated bricks making is heat insulation all good with sound-proofing properties, and more existing aerated bricks is significantly improved; The present invention is simultaneously by optimization of C/C composites materials, and intensity of the present invention, frost resistance are significantly improved.
