Description

A kind of waterproof anti-corrosion aerated bricks and preparation method thereof
Technical field
The invention belongs to brick field, particularly relate to a kind of waterproof anti-corrosion aerated bricks and preparation method thereof.
Background technology
Aerated bricks is also called air-entrained concrete building block, application very extensive, is mainly used in the load-bearing wallings such as the materials for wall in machinery plant and covil construction, infilled wall, floor and roof boarding and non-bearing material and filling enclosure wall around.
Current aerated bricks has become the leading product of building material industry, and country progressively prohibits the use clay solid brick, is instead exactly air-entrained concrete building block gradually, autoclaved brick.
Aerated bricks have lightweight, thermal and insulating performance good, shock resistance is strong, good processability, have certain high thermal resistance, good, the adaptable feature of sound-proofing properties, can according to the different starting material in locality, different condition is carried out amount body and is surely made, raw material sources is extensive, river sand, flyash, ore in sand form etc. can be selected, suit measures to local conditions, can be salvaged, environmental, really turn waste into wealth.
But along with the development of building trade, buildings is more and more higher, moulding is more and more peculiar, require all to increase to the intensity, density, shrinkage value, frost resistance etc. of aerated bricks, improving constantly in addition along with people's living standard, also more and more higher to the requirement of environment, there is higher requirement to the heat-insulating property of buildings, sound absorption qualities, radioactivity, even require that buildings has the performance of body health benefits, therefore as required, the aerated bricks developing excellent performance is more imperative.
Summary of the invention
The object of the present invention is to provide a kind of waterproof anti-corrosion aerated bricks and preparation method thereof, this aerated bricks water resistance is excellent, and energy protection against corrosion, and anti-steel bar corrosion, intensity is high, and wear resistance is good, water-tolerant.
Technical scheme of the present invention is as follows:
A kind of waterproof anti-corrosion aerated bricks, is characterized in that being made up of the raw material of following weight part: cement 11-13, unslaked lime 14-16, modification sawdust 9-11, citric acid 1-2, gypsum 7-9, flyash 45-50, glass flake 2-3, methylisothiazolinone 1-1.5, slate flour 3-4, linolic acid 0.5-0.8, ether of cellulose 0.5-0.7, acetic acid 0.3-0.5, aluminium powder cream 0.07-0.12, borax 0.2-0.5, water are appropriate;

The preparation method of described waterproof anti-corrosion aerated bricks, is characterized in that comprising the following steps:
(1) by cement, unslaked lime, gypsum, flyash, slate flour mixing, send into grinding in ball grinder and become 50-100 order particle, then mix with the composition except aluminium powder cream, be that 0.56-0.57 adds water by ratio of water to material, stir, then add aluminium powder cream, stir and obtain slurry;
(2) slurry that (1) step obtains is poured in mould, obtain brick idiosome;
(3) brick idiosome is put into steam-cured still to vacuumize, then in 1.7-1.9 hour, pass into steam equably, make the temperature of steam-cured indoor rise to 170-180 DEG C, pressure reaches 11-12MPa, keeps constant 9-11 hour;
(4) let off steam equably in 1.7-1.9 hour, make the temperature of steam-cured indoor be down to less than 70 DEG C, go out still, place 28-30 days and get final product.
Beneficial effect of the present invention
Aerated bricks water resistance of the present invention is excellent, and energy protection against corrosion, anti-steel bar corrosion, and intensity is high, and wear resistance is good; By using modification sawdust, reduce dry density and drying shrinkage value, and by the sawdust of used oil process, improve the water tolerance of aerated bricks; This aerated bricks also has good sound insulation, heat-proof quality.
