Background technology
The industrial residue that discharges when phosphogypsum is Wet-process phosphoric acid (WPPA), main component is a terra alba, contains impurity such as a spot of phosphorus, fluorine and organism.Because the influence of detrimental impurity makes it can not be directly used in the production building materials of gypsum in the phosphogypsum.Brushing gypsum is the less energy-consumption wall plastering material of advocating energetically both at home and abroad in recent years.Compare with sand-cement slurry with lime mortar, brushing gypsum is affine to human body, and energy consumption is low, good water-retaining property, and cohesive force is strong, the problem that ftractures, plays drum, comes off can not occur.But the single-phase brushing gypsum performance mutability of traditional plaster of paris preparation is wayward; The mixed phase brushing gypsum is produced complicated, and costs an arm and a leg, and cost is higher.Utilize phosphogypsum preparation brushing gypsum, not only turn waste into wealth, energy-saving and emission-reduction, and also product cost is lower, and the market competitiveness is strong.
On " New Building Materials " the 10th phase in 2005, published " the friendly process design of phosphogypsum based plastering gypsum ".The document has been studied the preparation technology who builds gypsum with phosphogypsum capital construction, has prepared phosphogypsum based plastering gypsum, has proposed the friendly process principle of design that phosphogypsum utilizes.Its brushing gypsum component is built gypsum for phosphogypsum capital construction: the trisodium citrate retardant: inorganic mineral water-holding agent=100:1:3.Adding retardant and water-holding agent have been studied in the document, in addition modification preparation brushing gypsum of gypsum is built in capital construction to phosphogypsum, but singly mix trisodium citrate retardant and inorganic mineral water-holding agent owing to only selected for use, do not adopt other modified measures, thereby the intensity of the brushing gypsum of preparation is lower, it is relatively poor to bond, and cost is higher.
The production technique that the present invention adopts is a common process.
Summary of the invention
The objective of the invention is to the deficiency at the technology of above-mentioned appearance, a kind of phosphogypsum based plastering gypsum is provided, this brushing gypsum workability is good, and operable time is long, and anti-folding, ultimate compression strength height have better splitting resistance and cohesiveness, and cost is lower.
In order to realize the foregoing invention purpose, its technical scheme is:
Phosphogypsum based plastering gypsum comprises following component and mass percent:
Gypsum 75～95 is built in phosphogypsum capital construction
Ash calcium powder 1～3
Retardant 0.1～0.5
Compound water retaining agent 1.1～5.5
Ethene-vinyl acetate between to for plastic emulsion copolymer powder 0.3～1
Filler 0～20
Wherein:
Gypsum is built in phosphogypsum capital construction: with the plaster of Paris of phosphogypsum preparation, performance must satisfy the requirement of GB9776-1988 " plaster of Paris ";
Retardant: citric acid or tripoly phosphate sodium STPP;
Compound water retaining agent:
Methyl cellulose ether or hydroxypropyl methyl cellulose ether 0.1～0.5
Wilkinite 1～5;
Filler: talcum powder or quartz sand.
The present invention compared with prior art has following technique effect:
(1) workability is good, and operable time is long, not sticking trowel;
(2) anti-folding, ultimate compression strength are higher, and cost is lower;
(3) rendering layer flawless does not play ash, and hollowing does not bond firmly good stability.
Utilizing the primary problem that solves of plaster of Paris preparation brushing gypsum of phosphogypsum preparation is the slow setting problem of plaster of Paris, selects suitable retardant, can guarantee that brushing gypsum has the operable time and the minimum intensity range of decrease preferably.The presetting period of plaster of Paris is generally in 10min, and the operable time of brushing gypsum should not be lower than 60min, and adopting retardant is unique selection.The present invention adopts citric acid, tripoly phosphate sodium STPP gypsum special retarder, has not only regulated the time of coagulation of brushing gypsum effectively, and guaranteeing has time enough to carry out constructing operation, and less to the influence of intensity.When adopting 0.3% citric acid as retardant, the presetting period can extend to more than the 90min, and operable time prolongs greatly.
Water-retentivity is the important technology index of brushing gypsum, and good water-retentivity can be avoided brushing gypsum plastic cracking and surperficial efflorescence.Usually adopt single water-holding agent technology, ether of cellulose is the commodity water-holding agent of using always.Different water-holding agent kind and volume improve the water-retentivity difference of brushing gypsum, and wherein methyl cellulose ether water conservation effect is best, but its volume is bigger, and cost is higher.The present invention adopts the composite water conservation technology, has improved the water-retentivity of phosphogypsum based plastering gypsum under lower cost greatly.Initiate inorganic water-holding agent component wilkinite is a laminate structure, and the intensive water-absorbent is arranged, and has water retention, can effectively reduce latter's volume with the compound use of methyl cellulose ether, reduces the material cost of brushing gypsum preparation.Adopt 0.5% hydroxypropyl methyl cellulose ether and 5% swelling soil phase compound brushing gypsum, the brushing gypsum that water retention is not mixed water-holding agent has improved 256%, and greatly reduces the cost of brushing gypsum.
In order to improve the application property of brushing gypsum, can mix a certain proportion of inorganic inert filler.Increase with the filler volume, prolong the time of coagulation of brushing gypsum, and blade coating, grinability turn for the better, but intensity, cohesiveness reduce.Talcum powder, quartz sand etc. can effectively improve the workability of brushing gypsum, strengthen effect of prestressed and weathering resistance, and have reduced the cost of brushing gypsum.
In order to improve the adhesive property of brushing gypsum, the present invention has also added ethene-vinyl acetate between to for plastic emulsion copolymer powder in process for preparation, has improved the adhesive property and the workability of brushing gypsum well.The phosphogypsum based plastering gypsum of admixture 0.8% ethene-vinyl acetate between to for plastic emulsion copolymer powder, its shear bonding strength reaches 0.68MPa, does not mix the raising 57% of latex powder.
In addition, for in and phosphogypsum capital construction build phosphoric acid impurity residual in the gypsum, the present invention has also added a spot of alkaline constituents-grey calcium powder, reduced impurity effectively to the brushing gypsum Effect on Performance, the brushing gypsum that can make the anti-folding of phosphogypsum based plastering gypsum, ultimate compression strength not mix alkaline constituents improves 26%, 32% respectively.
