Description
Technical field
The invention belongs to building material technical field, and in particular to a kind of based on ardealite hydraulicity composite gel material
Light heat-insulation mortar.
Background technology
Ardealite be in phosphoric acid wet production with sulfuric acid treating phosphorite when the solid slag that produces, wherein often producing 1 ton of phosphorus
Acid can produce the phosphogypsum slag of (4.8-5.0) ton.According to the difference of crystal water content in ardealite molecular structure, ardealite is again
Two water type ardealites and half water type ardealite can be divided into.At present, it is up to using Wet Processes of Phosphoric Acid year discharge ardealite in the world
1.5 hundred million tons, and China, used as phosphoric acid, production of phosphate fertilizer big country, ardealite annual emissions exceed 20,000,000 tons, and wherein most is stacked
Process, utilization rate is less than 10%.
To the end of the year 2011, the accumulating amount of China's ardealite brings serious environmental problem and resource just more than 300,000,000 tons
Recycle problem.Since " 12 ", China just puts into effect many corresponding exploitation policies, it is intended to improve ardealite synthesis
The low problem of utilization rate.In recent years, with the progress of ardealite evaluation and exploration technology, ardealite recycling problem is continuous to be obtained
To solve, and mainly applied in terms of three below：In terms of one is building materials of gypsum, ardealite prepares plaster of Paris and then life
Produce various gypsum products；In terms of two are chemical industry, ardealite Sulphuric acid co-producing cement；In terms of three are agricultural, Producing Potassium Sulfate From Phosphogypsum,
The compound fertilizers such as ammonium sulfate, ammonium-potassium sulfate.
Thermal insulation mortar is, with various aglites, to be equipped with Binder Materials, and blend other fillers, agitated mixing and make
A kind of Prefabricated dry powder mortar.It is mainly used in building exterior wall heat preserving, there is easy construction, good endurance.At present, market
There is the shortcomings of power consumption is high, heat insulation effect is not good mainly with cement as Binder Materials in upper thermal insulation mortar used.
Ardealite base light heat-insulation mortar be prepared with the complex cementitious systems such as ardealite, cement and lightweight fine aggregate and
Into the technology is capable of achieving the resource efficient utilization of ardealite, solves the problem of environmental pollution that industrial phosphogypsum heap abandons generation.
Ardealite base thermal insulation mortar can be divided into calcinated type and non-calcinated type by different according to ardealite pretreatment mode again, due to phosphorus stone
Cream thermal insulation mortar cohesive force prepared after calcining is strong, high insulating effect, so domestic big multipair industrial phosphogypsum waste residue is calcined
After be used.The domestic research for ardealite base light heat-insulation mortar has formed many Patents achievements, patent of invention：
A kind of preparation method of ardealite base composite thermal insulation mortar (105084852 A of CN), which adopts calcinated type ardealite, silicate
Cement, alkali-activator and methylcellulose complex cementitious system and expanded perlite, polystyrene foam, slag and poly- silica
Alkane is formulated；Patent of invention：A kind of ardealite base thermal insulation mortar containing glass bead (104163613 A of CN), which adopts
Calcinated type ardealite, glass bead, retarder and modifying agent are formed.It is all as representative with above-mentioned ardealite base thermal insulation mortar
In many patents, there is intensity is not high, cohesive force is low, drying shrinkage is big and heat preservation and soundproof effect is poor etc. in prepared thermal insulation mortar mostly
Shortcoming, is unfavorable for dissolving and applying for industrial waste ardealite.
The content of the invention
The purpose of the present invention is to prepare a kind of light heat-insulation mortar based on ardealite hydraulicity composite gel material.
A kind of light heat-insulation mortar based on ardealite hydraulicity composite gel material proposed by the present invention, by phosphorus stone

After in the present invention, incorporation sodium gluconate or sodium citrate can delay mix thermal insulation mortar to add water to a certain extent
Condensation hardening, be easy to constructing operation.Further, since expanded perlite density is low, to occur dividing after avoiding thermal insulation mortar from adding water
Layer phenomenon, mixes cellulose ether or hydroxymethyl cellulose ether can improve gelling system internal bond power, and repression of swelling perlite exists
Occur the phenomenon for floating in slurry, improve the homogeneity of ardealite base thermal insulation mortar.Poly carboxylic acid series water reducer is used as a kind of high property
Energy concrete admixture, mixes mix in thermal insulation mortar with powder and uniformly, can significantly improve mortar rheological property after adding the water,
It is easy to constructing operation.In order to further reduce mortar apparent density, polyethers air entraining agent is present invention employs, itself and polycarboxylic-acid
Water reducer has well adapting to property.Further, since China's river sand resource is in short supply, the aggregate choosing in ardealite base thermal insulation mortar
With sea sand, and needed to wash sea sand for several times before incorporation to remove a large amount of chlorions of sea sand remained on surface, reduce
Impact of the sea sand to thermal insulation mortar endurance quality.
The present invention is a kind of light heat-insulation mortar based on ardealite base hydraulicity composite gel material, is meeting insulation
On the premise of mortar heat-insulating sound-insulating, light energy conservation, industrial phosphogypsum solid slag is adopted to greatest extent for raw material, with very
