Description
Technical field
The invention belongs to building material field, relate particularly to a kind of ardealite based self-leveling material and preparation method thereof.
Background technology
Ardealite is topmost industry byproduct during China phosphorous chemical industry produces, be phosphatic fertilizer company discharge in process of production with two
H 2 O calcium sulphate is the precipitate of main component.Often produce one ton of P2O54.5～5.5 tons of ardealites will be discharged.Phosphorus stone for a long time
Cream is because making its Utilizing question become an international technology difficult problem, so mainly taking to store up containing impurity such as certain phosphorus, fluorine, Organic substances
Measure.At present, ardealite can be applicable to the fields such as cement industry, construction material, chemical fertilizer industry and agricultural, but utilization is little.
China in 2012 produces 13,000,000 tons of phosphate fertilizer, ardealite generation amount nearly 70,000,000 tons, accumulative volume of cargo in storage more than 300,000,000 tons,
Ardealite comprehensive utilization ratio is less than 10%.
Crystal whisker of gypsum refers to the fibrous monocrystal of two water, half water or dead plaster, is a kind of function admirable, cheap
New function material.The conventional raw material preparing crystal whisker of gypsum is the natural gypsum, mainly has hydro-thermal method and normal pressure acidization method two kinds.
Crystal whisker of gypsum has high tensile strength and elastic modelling quantity, is the industrial materials of a kind of high value, resin, rubber, coating,
Papermaking is made reinforcing agent or functional type filler it can also be used to friction material, construction material, encapsulant, insulation and fire proofing
Deng.
Self-leveling material is a kind of with inorganic coagulation material or organic material as base material, with additive and the thin fluvial sand etc. such as super plasticizer
The building ground alignment material being dry mixed.In actual application, by the ratio of mud of regulation add water mix uniformly after, machinery
After pumping or artificial construction, under self gravitation effect, form flat surface by slurry, eliminate artificial floating link, construction speed
Degree greatly speeds up.And surface smoothness after self-leveling material is formed is good, intensity is the highest.
Self-leveling material includes inorganic self-leveling material and two aspects of organic self-leveling material.Inorganic self-leveling material includes Gypsum Fibrosum
Base, cement based and mixed base Binder Materials.At present, gypsum-based self-leveling material has the feature of light weight, it is possible to reduce ground is born
Weight, its research and application are more and more extensive.
Domestic have many inorganic self-leveling materials, and it is the highest that the place of its deficiency is mainly rupture strength, and production cost is higher.Phosphorus stone
Cream whisker can significantly improve material rupture strength, reduces production cost.But do not see that employing crystal whisker of gypsum is to improve Gypsum Fibrosum at present
The report of based floor self-leveling material.
Summary of the invention
The technical problem to be solved is to propose a kind of ardealite based self-leveling material and preparation method thereof, and main purpose is
Improve the high added value that ardealite utilizes, on the basis of original gypsum-based self-leveling material, promote ardealite based self-leveling material
Various performances, especially in terms of rupture strength, reduce production cost simultaneously.
It is as follows that the present invention solves the technical scheme that above-mentioned technical problem used: a kind of ardealite based self-leveling material, its raw material group
One-tenth percentage is: β Gypsum Fibrosum powder: 10～20%；High strength gypsum powder: 20～30%；Gather materials: 30～40%；Ardealite
Whisker: 5～15%；Breeze: 2～4%；Cement 3～8%；Retarder: 0.1～0.3%；Water-retaining agent: 0.05～0.10%；Subtract
Water preparation: 0.1～0.5%.
By such scheme, described high strength gypsum powder is to prepare through the reaction of water at atmospheric pressure full-boiled process, and its strength grade is at more than 30MPa.
By such scheme, described ester exchange at phosphorus is commercially available phosphogypsum dihydrate whisker, to the requirement of its quality is:
CaSO4·2H2O content is more than 98wt.%, tensile strength 21.0GPa, and tensile modulus is 173GPa, average diameter 2-4 μm,
Average length is 40-130 μm.
By such scheme, described gathering materials for fluvial sand, modulus of fineness is 2.0～2.5.
By such scheme, described cement is sulphate aluminium cement.
By such scheme, described breeze is ground granulated blast furnace slag.
By such scheme, described β Gypsum Fibrosum powder is commercially available Gypsum Fibrosum powder, and its quality is: fineness is 0.074mm square hole screen sieve
Yuing 1%, the presetting period is 6min, and final setting time is 10min, and over dry comprcssive strength is 11MPa, and over dry rupture strength is 4.6MPa.
By such scheme, described retarder is any one in tartrate, citric acid, citrate or SC retarder,
Water-retaining agent is any one in methyl cellulose ether, hydroxyethyl cellulose or carboxymethyl cellulose, and water reducer is polycarboxylic acids diminishing
Any one in agent or sulfonated melamine.
The preparation method of described ardealite based self-leveling material, it comprises the following steps:
1) according to percentage by weight by ester exchange at phosphorus 5～15%, breeze 2～4%, cement 3～8%, retarder 0.1～0.3%,
Water-retaining agent 0.05～0.10%, water reducer 0.1～0.5%, once it is uniformly mixed；
2) according to percentage by weight successively by β Gypsum Fibrosum powder 10～20%, high strength gypsum powder 20～30%, gathering materials 30～40% adds step
Rapid 1) gained compound carries out secondary stirring mix homogeneously；
3) by step 2) raw material that mixes of gained and water in the ratio mix and blend of 1:0.4-0.6, prepare low cost ardealite
Based self-leveling material.
The ultimate principle of the present invention: β Gypsum Fibrosum powder, high strength gypsum powder and cement are main gelling material, is the gravity flow of ardealite base
The main source of the flat strength of materials.Ester exchange at phosphorus increase intensity be primarily due between gypsum fiber there is certain table
Face adhesion, it combines in ardealite based self-leveling material, forms certain structural network.When phosphorus whisker volume is at 5%-15%
Time, the network integration power between whisker is relatively big, and while not reducing comprcssive strength, rupture strength is remarkably reinforced.Work as ardealite
When whisker volume is less than 5%, between whisker, spacing is relatively big, and the adhesion of generation is too small or does not produce adhesion, and whisker only plays filler
Effect, reinforced effects is inconspicuous；When ester exchange at phosphorus volume is more than 15%, too much crystal whisker of gypsum is connected with each other, half water
The dihydrate gypsum crystalline network that Gypsum Fibrosum is formed is destructurized, shows as the resistance to compression of phosphorio self-leveling material, rupture strength can be
Reduce.
The method have the advantages that: compared with existing gypsum-based self-leveling material, present invention utilizes substantial amounts of trade waste ardealite；
Compared with ardealite based self-leveling material, the product quality of the present invention is more preferable, has been improved particularly rupture strength, and production cost also has
Reduced.The ardealite based self-leveling material of preparation fully achieves in JC/T1023-2007 " gypsum base gravity flowing levelling mortar "
To 30min fluidity loss, presetting period, final setting time, rupture strength, comprcssive strength, the requirement of shrinkage factor.Particularly as follows:
By adding α high strength gypsum powder, breeze, product strength is greatly improved；Add sulphate aluminium cement, improve the early stage of product
Intensity；Add β plaster of Paris and crystal whisker of gypsum, reduce production cost, improve the rupture strength of product；Interpolation retarder,
Water-retaining agent, water reducer etc., improve the setting time of product, adhesion strength, the thick water consumption of mark etc., and workability is better.
