Description
Technical field
The present invention relates to building material field more particularly to a kind of water-fast ardealite self-leveling materials.
Background technology
Ardealite is most important industry byproduct in phosphorous chemical industry production process, is that phosphatic fertilizer company is discharged in process of production
With calcium sulphate dihydrate sediment as main component.By-product ardealite is very big due to measuring, and causes serious pollution to the environment, and ardealite is answered
Make great efforts to solve the problems, such as with always this field.At present, there are many reports and practical application for recycling ardealite.
Self-leveling material is a kind of material levelling for building ground, at present, has had and has much been used for ardealite certainly
The report of levelling material, for example, patent publication No. is CN104692755A, patent name is a kind of ardealite based self-leveling material
Material and preparation method thereof patent, for another example, patent publication No. CN102643065A, patent name for gypsum base from
The Chinese patent application of levelling material；
But greatest problem existing for existing half water Self-levelings of ardealite β is water-fast sex chromosome mosaicism, existing ardealite base gravity flow
Test block made of flat material is soaked in and interior when 24 is small in water surface erosion occurs；Moreover, compression strength is generally not more than
25MPa.Moreover, existing ardealite based self-leveling material, the content of wherein ardealite is relatively low, generally below 30%, this is for phosphorus
The underutilization of gypsum.
The content of the invention
The purpose of the present invention, which is that, provides a kind of water-fast ardealite self-leveling material, to solve the above problems.
To achieve these goals, the technical solution adopted by the present invention is such：A kind of water-fast ardealite self-leveling material, by
Following component compositions by mass percentage：

Add up to 100%.
The ardealite of the present invention, preferably beta-type semi-hydrated gypsum, beta-type semi-hydrated gypsum are quick under the unsaturation steam of overheat
It is formed, therefore the crystallinity of its crystal grain is poor, more loose, tiny and irregular, form is mostly sheet, is on a small quantity lamellar crystalline substance
Type；Beta-type semi-hydrated gypsum yield is big, at low cost.
The present invention use the β gypsum-based self-leveling materials that ardealite is prepared for raw material, with intensity height, good fluidity, resistance to
The characteristics of aqueous good, cost-effective, compression strength is up to 30-35 megapascal.The material of the present invention is by exciting agent to gypsum, cement
With the excitation of flyash, adjustment of the cooperation pH adjusting agent to slurry pH value is adjusted the pH value of ardealite slurry brilliant to optimum
Under the alkaline environment of type growth, dihydrate gypsum crystal is tiny in needle bar shape, the predominantly bigger needle-shaped crystalline substance of major diameter in hardenite
Body crisscross ground weave in, overlap joint degree is higher between each other, and crystallization contact point is more, generates compact texture, so as to
Significantly improve compression strength.
The addition of hydraulic material and waterproof material：On the one hand change the composition of slurry phase, reduce solubility, improve softening
Coefficient；On the other hand by reducing material surface energy, material hydrophobicity is improved.
The present invention mutually cooperates with other compositions particularly by the addition of appropriate mica powder, significantly improves the resistance to of material
Aqueous energy：The Mohs' hardness of mica powder is 2-3, and full of elasticity, flexible, wear resistence and wearability are good；High temperature insulation is insoluble in acid
Aqueous slkali, chemical property are stablized, and the barrier of unique two-dimensional sheet, shielding ultraviolet light, steady chemical structure effectively improve slurry
Permeability resistance, weatherability, wearability and the corrosion resistance of material.
In addition, the material of the present invention is without any radioactive element, it is environmentally protective.
As preferred technical solution, it is made of following components by mass percentage：
Ardealite 50%, cement 5.2%, flyash 8%, quartz sand 12.3%, PH conditioning agents 6%, exciting agent 5%, mica powder 5% can be again
Dispersed latex powder 4%, water-reducing agent 2%, water-retaining agent 1%, 0.5 % of retarder, waterproofing agent 0.5%, antifoaming agent 0.5%.
As preferred technical solution, the pH adjusting agent is calcium hydroxide.
As preferred technical solution, the redispersible rubber powder is vinylacetate and ethylene copolymer rubber powder.Such as
" Mei Kai " the redispersable latex powder MK-1620 of Jinan Yue Kai Chemical Co., Ltd.s production may be employed.
As preferred technical solution, the water-retaining agent is hydroxypropyl methyl cellulose.
As preferred technical solution, the waterproofing agent is organosilicon.
