Abstract
The invention discloses a granite-like decorative plate comprising an ardealite substrate and a preparation method thereof. The granite-like decorative plate is prepared from the following components in parts by weight: 30-80 parts of ardealite, 15-60 parts of yellow phosphorus slag, 1-20 parts of cement, and 0.1-10 parts of quick lime. The yellow phosphorus slag, the cement, the quick lime and the ardealite are mixed and aged; therefore, the acidity of the ardealite is eliminated; the content of soluble matters in the ardealite is reduced; the solidification property of the ardealite is increased; by means of addition of the cement, the solidification property of the ardealite is further increased; the ardealite is modified and subjected to hydration reaction with the yellow phosphorus slag so as to generate a main product, namely ettringite crystals; and therefore, the strength and the water resistance of the granite-like decorative plate are obviously increased.
Description
Technical field
The present invention relates to building material technical field, specifically, relate to a kind of artificial grantie decoration plate and preparation method thereof.
Background technology
In production process of phosphoric acid, often produce one ton of P
2o
5by-product five tons of phosphogypsums, the every by-product phosphogypsum every year of medium-sized phosphoric acid production enterprise is about 3,500,000 tons.So many phosphogypsum not only needs a larger cinder yard, but also can cause pollution of waterhead.At present, the most frequently used phosphogypsum treatment process has following four kinds:
First method: phosphoric acid cream is used for backfill pit.According to statistics, when not adopting phosphogypsum to backfill mine working, mine working filling cost accounts for 1/3 of mining, and attal accounts for 80% of filling cost, fill mine working with phosphogypsum, fill cost and account for 1/5 of mining cost, not only saved filling cost, and improve utilization of three wastes rate, decrease environmental pollution.But, due to factors such as phosphogypsum jelling agent casting resin viscosity is high, sedimentation fast, condensation is fast, many, the easy pluggings of fine particle, difficult cleanings, at present, conventional method adopts mixture workshop to lead to long-distance Automobile Transportation to mining area, Filling Station is set up in hole, ore deposit nearby, completes filling by pump delivery to flow processs such as roadways.Automobile Transportation generally has the distance of 30 km from ardealite storage yard to Filling Station, and major part is sky way.Though the car of transport phosphogypsum is common double-bridge vehicle without the car of the easy airborne dust of sealing, fortune phosphogypsum jelling agent is that tank car has sealing but vehicle body length drives the larger Road transport of existence and traffic safety hidden danger on sky way, and phosphogypsum jelling agent warehouse-in forklift is had bad luck, is sieved and be filled with airborne dust and noise, all there is larger safety and pollution hidden trouble to environment with slurry, personnel, equipment.Adopt pipeline transportation, Filling Station is selected unreasonable because of its phosphogypsum and phosphogypsum jelling agent ratio and conduit slope, camber, material design, frequent generation blocking pipe, cause the equipment safety operation hidden danger such as equipment superpressure, motor overload and cannot clean after line clogging and only have destructive dismounting, pipeline waste is comparatively large, cost is higher, continuous production is low, equipment and personnel exist larger safety in production and run hidden danger.
Second method: by the agent of phosphogypsum production Flocculated Cement.The crystal habit of phosphogypsum is identical with the plaster of paris, for prismatic or cylindricality plate crystal, chemical composition and plaster of paris composition basic simlarity, but due to containing solubility Vanadium Pentoxide in FLAKES, phosphoric acid salt, soluble fluoride, insoluble Vanadium Pentoxide in FLAKES and organic impurity etc., the hydration time of cement can be extended, reduce early strength and extend time of coagulation, therefore phosphogypsum directly can not be used as the retardant of cement.Phosphogypsum is needed to process, method conventional is at present through art breading such as washing, pre-treatment, drying and calcinings by phosphogypsum, it is low that this method obtains cement setting retarder cost, but by the long flow path of producing cement retarder through phosphogypsum, facility investment is large, and still inevitably containing Vanadium Pentoxide in FLAKES and fluorochemical in the flocculation agent produced, make the hydration time of cement and time of coagulation longer.
The third method: by phosphogypsum sulphur ammonium and calcium carbonate, the method utilizes ammonia and carbonic acid gas that phosphogypsum is changed into sulphur ammonium and calcium carbonate, and the specification of quality of the method to phosphogypsum is higher, and Production Flow Chart is long, and investment is large.
4th kind of method: phosphogypsum is used for improve alkaline soil.Containing Vanadium Pentoxide in FLAKES in phosphogypsum, cause phosphogypsum aobvious acid, its pH value is 1.5 ~ 4.5, can be used to the alkalescence in sweetening of the soil, and the compositions such as the phosphorus contained in phosphogypsum, iron, magnesium, silicon, zinc, sulphur and the calcium nutritive element that to be plant-growth necessary.
Above-mentioned several method has promoted the technical progress of China's phosphogypsum resource utilization, but above-mentioned technology fails to utilize phosphogypsum fully, and fundamentally can not solve the phosphogypsum present situation that pile up like a mountain.Therefore, there is people by phosphogypsum as the raw material preparing artificial grantie decoration plate, by the process phosphogypsum that this approach can be a large amount of, and can preferably phosphogypsum be fully utilized.At present, usually after phosphogypsum being mixed with a small amount of cement, paper pulp, fiber reinforced material etc., phosphogypsum fiberboard is made again after pressurization, due to phosphogypsum itself, not have gelling, water content high and containing characteristics such as plurality of impurities, the performance such as wear resistance, weathering resistance, ultimate compression strength of the phosphogypsum artificial grantie decoration plate adopting the method to produce is on the low side, is difficult to the service requirements reaching building and ornament materials.The patent application being used for phosphogypsum to prepare artificial grantie decoration plate has a lot, such as, patent CN101219881 discloses a kind of phosphogypsum composite material, it is for main raw material with phosphogypsum and urea-formaldehyde resin, be aided with resol, nut-shell, polyacrylamide, flyash, after above-mentioned raw materials mix and blend, then through extrusion molding and get final product, manufacture craft is simple.The patent No. is ZL200810233755.0, denomination of invention is " a kind of artificial grantie decoration plate utilizing industrial residue to produce ", it is with parts by weight, after phosphogypsum 10 ~ 40 parts, 5 ~ 15 parts, lime, cement 15 ~ 28 parts, water glass 0.02 ~ 0.05 part, water reducer 0.01 ~ 0.05 part, retardant 0 ~ 0.004 part, hardening accelerator 0 ~ 0.005 part and defoamer 0 ~ 0.008 part are mixed, be that 4:10 adds water and stirs according to ratio of water to material, then be poured in mould shaping, natural air drying.It has the advantage that manufacturing process is simple, production cost is low, have certain heat insulating effect.By phosphogypsum for the production of artificial grantie decoration plate, a kind of formula of research is simple, and production technique is simple, and produces the building products of good combination property, has significant economic implications.
Summary of the invention
In view of this, the object of this invention is to provide a kind of formula rationally, the simple artificial grantie decoration plate of preparation technology and preparation method thereof, to solve the phosphogypsum present situation that pile up like a mountain, and prior art produce the performance such as phosphogypsum artificial grantie decoration plate wear resistance, weathering resistance, ultimate compression strength on the low side and exist deficiency, phosphogypsum is used for produce decorative sheet, obtains larger economic benefit and social benefit.
