Abstract
The invention discloses an aerated brick produced by diatomite and a processing method of the aerated brick. The aerated brick is prepared by the following components in parts by weight: 45-55 parts of diatomite, 5-8 parts of cement, 10-15 parts of iron ore tailings, 5-10 parts of powdered carbon, 14-16 parts of quick lime, 4-5 parts of vermiculite, 0.03-0.05 parts of hydrogen peroxide, 5-10 parts of modified plant ash, 0.03-0.04 parts of oxyparaffin soap, 0.01-0.02 parts of aluminite powder and 0.3-0.5 parts of glass fiber. According to the processing method, the diatomite is adopted as an ingredient of the aerated brick, so that cost is low, and energy consumption is reduced. Furthermore, prepared aerated brick is good in heat-insulating property and sound insulation property, and the heat-insulating property and the sound insulation property are obviously improved in comparison with those of a conventional aerated brick. Meanwhile, strength and freezing resistance of the aerated brick are obviously improved by optimizing formula materials.
Description
Technical field
The present invention relates to the building material field, specifically belong to a kind of aerated bricks and working method thereof of utilizing diatomite to produce.
Background technology
Aerated bricks is the aerated bricks building block of producing by the autoclave at high temperature apparatus and process, namely 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 the relatively evening that this technology of China begins, totally fallen behind 40 years than abroad, 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.
The 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. all are the starting material of doing aerated bricks, and very superior of the performance characteristics of aerated bricks, but extraordinary working ability and heat insulation and insulated capacity are arranged, and very strong of plasticity-, extraordinary processing characteristics is arranged, and the research of aerated bricks raw material and processing technology need further to improve.
Summary of the invention
The object of the present invention is to provide a kind of aerated bricks and working method thereof of utilizing diatomite to produce.
The present invention adopts following technical scheme to achieve these goals:
The aerated bricks that utilizes diatomite to produce, 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, vermiculite 4-5, hydrogen peroxide 0.03-0.05, modification plant ash 5-10, oxidized paraffin wax soap 0.03-0.04, aluminium powder 0.01-0.02 and glass fibre 0.3-0.5.
Utilize the working method of the aerated bricks of diatomite production, may further comprise the steps:
(1) raw-material processing: starting material comprise diatomite, cement, iron ore tailings, powdered carbon, unslaked lime and vermiculite; Be crushed to fineness and reach the 180-200 order;
(2) stir: Xian Jiashui stirs separately, and then mix and blend also adds other surplus stocks in the raw material by weight;
(3) cast: the slurry that step (2) is stirred adds in the stock mould, obtains the brick idiosome;
(4) rest: the brick idiosome of step (3) is put into the chamber of resting, rest chamber sealing thermal insulation 55-65 ℃, rested time 2-2.5 hour;
(5) cutting: the brick idiosome that step (4) is rested is put into and is processed into certain desired size on the cutting machine;
(6) steam-cured: that the green compact of above-mentioned steps (5) at 0.9-1.1Mpa vapor cure 15-20h, are namely got the aerated bricks finished product.
Described modification plant ash is that plant ash is admixed the calcium lignin sulphonate agitating with epoxy Toenol 1140,1-2% that is equivalent to powder weight 1-2% is even, and oven dry is ground into 100-200 order powder and obtains.
Beneficial effect of the present invention:
The present invention is by adopting diatomite as the composition of aerated bricks, and is with low cost, reduced energy consumption; And the aerated bricks that makes is heat insulation all good with sound-proofing properties, and existing aerated bricks is significantly improved; Simultaneously the present invention is by the optimization of C/C composites materials, and intensity of the present invention, frost resistance are significantly improved.
