Abstract

The invention discloses application of silica powder in corrosion-resistance insulation board plastering anti-crack mortar. The corrosion-resistance insulation board plastering anti-crack mortar is prepared from, by weight, 400-550 kg of quartz sand, 300-400 kg of Portland cement, 50-100 kg of coal ash, 100-150 kg of the silica powder, 50-100 kg of ash-calcium, 4-6 kg of a water reducing agent and 20-40 kg of an additive. Compared with existing insulation mortar, the corrosion-resistance insulation board plastering anti-crack mortar is good in insulation effect, high in corrosion resistance and strong in adhesive strength, the preparation technology is simple, preparation is convenient and rapid, and production efficiency is greatly improved. The silica powder produced after cobblestone filtered out in the dry powder mortar preparation process is broken is utilized, the resource recycling rate is high, energy conservation and emission reduction are achieved, the mortar production cost is greatly reduced, and economic benefits are high.

Description

The application of silica flour in corrosion-resistant insulating plate Crack-resistance Front Mortar
Technical field
The present invention relates to the new green environment protection energy saving building building materials field of green building material, scrap concrete recycling, particularly relate to the application of silica flour in corrosion-resistant insulating plate Crack-resistance Front Mortar.
Background technology
Warming plate Crack-resistance Front Mortar is according to the deformation coefficient of layers of material in physical environment in insulation series, the features such as stress relief also combine that actual resistance to impact shock requires to carry out to design, and belong to the reinforced mortar that special-purpose thermal insulation material surface layer carries out anti-cracking waterproof.Not only may be used for external wall Surgery therapy, exterior wall internal insulation can also be used for, or be incubated inside and outside exterior wall simultaneously, and the insulation on roof and the thermofin of underground heat, design for energy-saving system provides certain handiness, has the advantages such as easy construction, good endurance, light weight, insulation, heat insulating ability be good.But existing warming plate Crack-resistance Front Mortar, in use expose many defects, as surperficial hollowing, ftracture, come off, easily go mouldy, poor corrosion resistance etc., therefore along with the reform of construction market, the construction quality of user to house is paid close attention to increasingly, and the material that quality is good, cheap is more and more subject to the favor of building trade and house colony.
In the preparation process of common dry-mix, sand needs to dry the particle filtering out more than 5 millimeters, and the particle of more than 5 millimeters is exactly pebbles, the silica flour produced in pebbles shattering process is a kind of resource, it is very unfortunate for can not being fully utilized, as solid waste process, cause very large waste, also serious pollution can be brought to environment, silica flour is utilizing through rational, the management of science and control, in mortar is produced, considerable income can be brought, the performance of mortar can be improved again, a lot of liftings is had to the quality of mortar, meet the fundamental policy setting up conservation-minded society that China advocates, to most of enterprise self, silica flour need not also be waste, land occupation, also be have certain detrimentally affect to the environment of enterprise and image.If silica flour is fully utilized, the difficult problem that enterprise's mortar cost is high can be solved, to enterprise under the stagnant overall situation of current building trade, have found new profit growth point, improve the core competitiveness of enterprise.But the silica flour selection by winnowing that pebbles fragmentation produces does not collect by enterprise at present, but is mixed in stone or sand, and resource recycling rate is low.In actual production, silica flour consumption can not get effective control, and the quality of silica flour also can not get keyholed back plate, and quality can not get ensureing, quality risk is higher.Under nowadays architectural environment, recovery of the capital is very large problem, and quality goes wrong the excuse easily causing downstream client to embezzle part of what should be issued engineering funds, and cost has high input, and economic benefit is low.
Therefore, in order to solve above-mentioned Problems existing, the present invention spy provides a kind of new technical scheme.
Summary of the invention
The object of this invention is to provide the application of silica flour in corrosion-resistant insulating plate Crack-resistance Front Mortar, can solve that existing mortar cost is high, the performance existing defects of mortar and the low technical barrier of recycling of recyclable waste reuse ratio.
The present invention is directed to the technical scheme that above-mentioned technological deficiency adopts is:
The application of silica flour in corrosion-resistant thermal insulation mortar, the raw material comprising following weight is made:
Quartz sand 400-550kg;
Silicate cement 300-400kg;
Flyash 50-100kg;
Silica flour 100-150kg;
Ash calcium 50-100kg
Water reducer 4-6kg;
Admixture 20-40kg.
Further, the granular size of described quartz sand is 70-140 order.
Further, described water reducer is one or more the combination in melamine condensates, sulfamate condenses.
Another object of the present invention is to provide the preparation method of the silica flour in a kind of corrosion-resistant insulating plate Crack-resistance Front Mortar, and concrete preparation method is as follows:
A, dry-mix dried in preparation process the pebbles that the particle filtered out is greater than 5mm and carry out fragmentation, then the silica flour selection by winnowing produced in shattering process is collected;
B, the silica flour that selection by winnowing is collected is selected powder by cyclone separator, meal continues broken, and fine powder blows into silica flour storage vault by ventilation skewed slot;
C, silica flour be homogenizing in silica flour storehouse, then enter worm conveyor be transported in cement flour truck, then get to the silica flour storehouse of mortar mixing plant.
The invention has the beneficial effects as follows: with existing thermal insulation mortar in contrast, the high and bonding force of high insulating effect of the present invention, corrosion resistance nature is strong, and preparation technology is simple, convenient and swift, substantially increases production efficiency; And the silica flour adopting the pebbles fragmentation filtered out in dry-mix preparation process to produce, resource recycling rate is high, energy-saving and emission-reduction, greatly reduces the production cost of mortar, high financial profit.
