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

A kind of aerated bricks and working method thereof of utilizing diatomite to produce
Technical field
The present invention relates to 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 autoclave at high temperature apparatus and process, adopt the brick product of other the various explained hereafter including 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 that do aerated bricks, and very superior of the characteristic of property 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 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.
The working method of utilizing the aerated bricks of diatomite production, comprises the following 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 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 55-65 ℃ that rests, time 2-2.5 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 0.9-1.1Mpa vapor cure 15-20h, are obtained to aerated bricks finished product.
Described modification plant ash is plant ash to be admixed to be equivalent to the calcium lignin sulphonate agitating with epoxy Toenol 1140,1-2% of powder weight 1-2% even, dries, and is ground into 100-200 order powder and obtains.
Beneficial effect of the present invention:
The present invention is by adopting the composition of diatomite as aerated bricks, with low cost, has reduced energy consumption; And the aerated bricks making is heat insulation all good with sound-proofing properties, 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.
