Description
Technical field
The present invention relates to fluorgypsum technical field, more particularly to a kind of modification fluorine gypsum powder for wall covering.
Background technology
Fluorgypsum is the byproduct in hydrofluoric acid (HF) preparation process, and national anhydrous HF yield is about 6.5 ten thousand t every year, and
Manufacture HF per ton and produce fluorgypsum about 3.5t, amount to the t/ of fluorgypsum yield about 230,000.Fluorgypsum main component is anhydrous sulphur
Sour calcium (CaSO4), because it is insoluble in, water, aquation are slow, coagulability is poor, and typically can not be by effective profit without early strength
With.At present, part fluorgypsum is used as the additive of cement, and most of fluorgypsum is just solid as one kind after slightly neutralisation treatment
Body discarded object is stored up, and directly stores up not only landed property, goes back contaminated soil and groundwater environment.
But fluorgypsum also has the advantage of its own：It is very high to produce raw material acid and the fluorite purity of fluorgypsum, and at reaction
In anhydrous state, it is anhydrous gypsum to produce fluorgypsum, CaSO4Content is up to more than 95%, is a kind of rare in gypsum resource
Grade resource.That is discharged from hydrogen fluoride reaction stove stacks without long-term, does not add the fresh fluorgypsum of water process to be used to produce
Plaster of Paris has following advantage again：Purity is high, impurity is few, without calcination processing, need not be broken, grinding workload is few.Modern fluorine
The utilization of gypsum are primarily used to the mineralizer and cement retarder of calcination of cement clinker, prepare brushing gypsum, production is built
Build plasterboard and coating material etc..But because fluorgypsum is a kind of anhydrous gypsum, hydration reaction is very slow, the dissolving speed in water
Degree is slow, if building materials are directly used in, such as wall covering, stitched when generally occurring within the insufficient strength of walling, meeting water softening and installation
Linking cracking a series of problems, such as.
Therefore, by being modified to gypsum, overcome its inherent shortcoming, it is used for modern wall covering, be to realize work
One of approach that industry byproduct fluorgypsum recycling effectively utilizes, and tool of preserving the ecological environment is of great significance.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of modification fluorgypsum for wall covering
Powder, the modified fluorine gypsum powder, not only meet the requirement such as water absorption rate, intensity of wall covering, and density is good, thermal conductivity factor
Low, product high comprehensive performance, and preparation technology is simple.
A kind of modification fluorine gypsum powder for wall covering proposed by the present invention, its raw material include by weight：Fluorgypsum
100 parts, coal ash powder 30-50 parts, alumino-silicate 2-5 parts, sulfate 3-8 parts, light material 3-6 parts, composite fibre 2-5 parts,
Waterproofing agent 2-5 parts, foaming control agent 1-2 parts；
Wherein, preparing the coal ash powder includes：100 parts of flyash are added to 200-240 parts 3-5mol/L mixed acid
In solution, 6-8h is stirred after being warming up to 100-120 DEG C, is cooled down, after standing 8-10h, filters, dry, pulverize, with 16-20 parts sea
Afrodite powder, 1-10 parts hydroxymethyl cellulose obtain the coal ash powder after mixing, wherein the mixed acid solution is by mole matching somebody with somebody
Than for 1:3-5 HCl and H2SO4It is formulated；
Preparing the modification fluorine gypsum powder for wall covering includes：Fluorine gypsum powder is broken to particle diameter≤2mm, add with
Stirred after 15-25wt% water on the basis of fluorgypsum, alumino-silicate stirring 1-2h, cooling are added after being warming up to 30-40 DEG C
15-20h is stood, sulfate is added and mixes, be calcined 1-3h at 80-180 DEG C, be cooled to room temperature, it is 5- to add water regulation humidity
10wt%, sequentially add coal ash powder, light material, composite fibre, waterproofing agent, foaming control agent mix, be finely ground to particle diameter≤
The modified fluorine gypsum powder is obtained after 0.147mm.
Preferably, the raw material of the modification fluorine gypsum powder for wall covering includes by weight：100 parts of fluorgypsum,
Coal ash powder 35-45 parts, alumino-silicate 3-4 parts, sulfate 5-6 parts, light material 4-5 parts, composite fibre 3-4 parts, waterproofing agent
3-4 parts, foaming control agent 1-2 parts.Preferably, the coal ash powder is 800-900 mesh.
Preferably, described alumino-silicate is kaolin, andalusite, the one or more in gangue, the sulfate
For the one or more in aluminum sulfate, alum, potassium sulfate, zinc sulfate, barium sulfate.
Preferably, the light material be by weight proportion be 1:5-7:3-5 expanded perlite, expanded vermiculite, polyphenyl
