Further, described powder economization agent is METOLATP871 powder economization agent, white powder, and activeconstituents can be completely soluble in water, and its effective constituent is the diatomic alcohol compounds on carrier, and aerated density is 400g/L.
Further, described water-resisting agent is ferric chloride waterproofing agent;
Described water reducer is methyne sodium naphthalene sulfonate (MF) water reducer.
Further, the physical dimension of the efficient homogeneous heat insulation building block of described A level fp can be come to determine voluntarily as required, and can cut.
Present invention also offers the preparation method of the efficient homogeneous heat insulation building block of a kind of A level fp, it is characterized in that, comprise the following steps:
(1) take raw material according to above-mentioned proportioning, then the haydite taken and haydite fragment particle, slag, perlite, perlite powder, cement, flyash, silicon ash, water reducer, water-resisting agent, powder economization agent are mixed, stir with stirrer;
(2) water taken and perlite properties-correcting agent are mixed, add in the material stirred in step (1), continue to stir, until hand is grabbed and agglomeratingly not scattered;
(3) building block extrusion equipment molding device sent into by the material that will process through step (2), with the compression factor extrusion molding of about 2:1;
(4) the material web mould of extrusion molding in step (3) is sent into curing room maintenance, obtain the efficient homogeneous heat insulation building block of A level fp of the present invention.
Mechanism of the present invention is: with cement as gelling material, haydite and fragment thereof and perlite is adopted to hold concurrently lagging material as aggregate, and carry out rational gradation composition, using flyash, slag etc. as filler, suitable interpolation respective additive improves every physical characteristics of the present invention, makes it to reach the technical requirements of this type of building material product and the index of energy-conservation 75%.Due to use is all inorganic materials, all belong to non-fire material, therefore fire resistance rating of the present invention can reach A1 level.
Gordian technique uses light ceramic and fragment thereof and perlite not only to carry out grating as aggregate but also as lagging material, adopt haydite and haydite fragment particle, the two uses simultaneously, optimize lagging material to hold concurrently the anti-compression property of aggregate, by haydite fragment particle, make grating more reasonable, solve the problem that the excessive ultimate compression strength caused of haydite particle diameter is inadequate.Employ the perlite properties-correcting agent developed voluntarily, this properties-correcting agent is mixed by methyl silicate hydrophober and silane hydrophober simultaneously, the two synergy.Methyl silicate hydrophober is under the effect of water and carbonic acid gas, generate methyl siliconic acid alcohol, methyl siliconic acid alcohol generates the thick insoluble waterproof macromolecular compound of several molecule on structured material surface and inside, and netted silicone resin, has good waterproof action.Meanwhile, silane hydrophober discharges ethanol and is combined with base material and is converted into silicone resin polymkeric substance, finally forms the silicone resin film of one deck hydrophobic on the pore surface of base material, further enhances hydrophobic effect.Both solved the contradiction of thermal conductivity and ultimate compression strength, and inhibit again the high characteristic of perlite water-intake rate to solve hydrophobic problem of the present invention, water-intake rate, frost resistance and weathering resistance are protected.
Perlite, both perlite powders use simultaneously, the space that perlite powder exists after effectively filling above material mixing, both ensure that the due heat insulation effect of perlite, and have served again the problem that product surface is smooth, attractive in appearance.
The invention has the beneficial effects as follows:
(1) the efficient homogeneous heat insulation building block of A level fp of the present invention solves the fire safety problem of current heat insulation building block, completely eliminate the disaster hidden-trouble of exterior-wall heat insulation infilled wall, solve the problem of energy-conservation 75% simultaneously, meet the national fire resistance rating about external wall thermal insulation product to require and higher energy conservation standard requirement, and production process is simple, has higher promotional value and boundless market outlook.
