Abstract
The invention discloses an aluminum powder paste for sand aerated blocks and a preparation method thereof. The aluminum powder paste for sand aerated blocks is prepared from the following raw materials in parts by weight: 180 parts of aluminum foil, 3 parts of white sugar, 4.5 parts of glycerol, 0.3 part of silicon oil, 5 parts of stearic acid, 0.5 part of triazole, 5 parts of TS-10 and 300 parts of water. Compared with the prior art, the aluminum powder paste has the advantages of uniform gas release and appropriate gas yield in the fly ash aerated blocks; the production tests prove that mold collapse accidents seldom occur; and thus, the aluminum powder paste enhances the qualification rate of the aerated blocks.
Description
Technical field
The present invention relates to a kind of sand aerated blocks aluminium powder cream, belong to concrete field of new.
Background technology
The concept of gas concrete is taking siliceous material (sand, flyash and containing silicon tailings etc.) and calcareous material (lime, cement) as main raw material, admixture foaming agent (aluminium powder), the light porous silicate product of making by technological processs such as batching, stirring, cast, precuring, cutting, steam pressure, maintenances.Because it contains a large amount of even and tiny pores, therefore named gas concrete after getting angry.
At present, aerated blocks has an insoluble technical problem in producing, and the aerated blocks mould rate of collapsing is higher, causes aerated blocks qualification rate in 80% left and right, the major cause of the mould that causes collapsing be exactly existing aluminium powder cream get angry weak effect, get angry inhomogeneous.Through the retrieval in Chinese patent literature, find no the record of this aspect.
Summary of the invention
The invention provides a kind of sand aerated blocks aluminium powder cream, solve the aerated blocks higher problem of mould rate of collapsing.
Technical scheme of the present invention is:
A kind of sand aerated blocks aluminium powder cream, is made up of the raw material of following parts by weight: aluminium foil 180, white sugar 3, glycerine 4.5, silicone oil 0.3, stearic acid 5, triazole 0.5, TS-10 5 water 300.
A preparation method for aluminium powder cream for sand aerated blocks, comprises the following steps successively:
1) ball milling powder after aluminium foil fragmentation is broken into 200 object aluminium powders;
2), in parts by weight, aluminium powder 180, white sugar 3, glycerine 4.5, silicone oil 0.3, stearic acid 5, triazole 0.5, TS-10 5 water 300 are mixed;
3) to step 2) form slurry carry out press filtration, press filtration to the mass percent of moisture content is 20 ~ 40%;
4) filter cake step 3) being formed is broken up, and after material scatters, packs.
Compared with prior art, aluminium powder cream of the present invention is got angry evenly in fly ash aerated, gas forming amount is suitable, through production test, rarely has the mould of collapsing to occur, and has improved the qualification rate of aerated blocks.
Embodiment
Below by specific embodiment, the present invention will be further described.
Embodiment 1
A preparation method for aluminium powder cream for sand aerated blocks, comprises the following steps successively:
1) ball milling powder after aluminium foil fragmentation is broken into 200 object aluminium powders;
2), in parts by weight, aluminium powder 180, white sugar 3, glycerine 4.5, silicone oil 0.3, stearic acid 5, triazole 0.5, TS-10 5 water 300 are mixed;
3) to step 2) form slurry carry out press filtration, press filtration to the mass percent of moisture content is 20 ~ 40%;
4) filter cake step 3) being formed is broken up, and after material scatters, packs.
Embodiment 2
A kind of proportioning raw materials of sand aerated blocks is made up of the material of following parts by weight: 35 parts, sand, 30 parts, lime, 10 parts, flyash, 15 parts of the aluminium powder cream of embodiment 1,30 parts, water;
Its processing step is:
1) various raw materials are mixed to formation slurry;
2) slurry step 1) being obtained is by die casting, then sends into and just supports the storehouse initial set of getting angry, and cuts into adobe after just forming type, obtains cutting aftershaping adobe;
3) steam-cured: by step 2) the cutting aftershaping adobe that obtains is placed in autoclave, and under 1.24 MPa saturation steams, maintenance goes out still for 12 hours, obtains air-entrained concrete building block.
In aerated blocks production process, do not find to collapse mould phenomenon.
All simple distortion of making in the situation that not departing from core of the present invention or amendment all fall into protection scope of the present invention.
