Description
Technical field
The invention belongs to material of construction preparing technical field, be specifically related to a kind of steamed brick that utilizes phosphorus mine tailing and phosphorus slag production and preparation method thereof.
Background technology
Along with exploitation and the utilization of phosphorus ore, phosphate rock resource increasingly dilution ，Yi Bei Ministry of Land and Resources can not meet one of 20 kinds of mineral of national economic development demand after listing 2010 in, classifies non-renewable strategic resource as.China's phosphate rock resource is abundant, but the 80%th, in, low-grade phosphate ore, mostly belong to high, the difficult collophanite selecting of foreign matter content, in order to meet the specification of quality of phosphoric acid by wet process to raw ore, must could meet phosphoric acid and high-concentration phosphate compound fertilizers Production requirement through cost-effective beneficiation enrichment, produce thus a large amount of mine tailings.
From mining ore out, after ore dressing extracts useful matter, the overwhelming majority is accumulated all the year round and is deposited in tailing dam, not only takies tract, and may cause severe contamination and destruction to ecotope.Phosphorus mine tailing granularity is thinner, piles up a place, if meet heavy rain, washes away, and easily causes and causes security incident by Serious geological disasters.
In addition, in order to change, China's building material industry is medium-term and long-term take clay as these a large amount of ways of wasting land resources, destroying arable land of raw material production vitrified brick, China forbade producing, using and selling solid clay brick in 30 days June in 2003, and advocated research and use industrial waste as building material.For this reason, the research and the application that utilize (one or several of above raw material) such as flyash, cinder, coal gangue, mine tailings, residue of chemical industry or natural sand, tidal land mud to prepare building material as main raw material are carried out fast, and reap rich fruits.But because phosphorus mine tailing belongs to the poor material that particle is thinner, it utilizes the following problem of ubiquity in process to need to improve in sundry item: (1) phosphorus mine tailing is used volume very low as fine aggregate; (2) cement cementitious material consumption is large; (3) due to complicacy and the ins and outs of phosphorus mine tailing composition, make the cement consumption of phosphorus tailing baking-free brick little, phosphorus mine tailing volume low strength when large, in order to improve the ultimate compression strength of goods, often need to add certain admixture (water reducer, exciting agent or retardant etc.), this has just increased production cost.
In view of above problem, not yet find a kind of High-Efficiency Utilization of Phosphorus mine tailing to produce the method for green structural material, this also further aggravates the detrimentally affect of phosphorus mine tailing to environment.
Phosphorus slag is the industrial residue discharging in producing yellow Phosphorus by electric oven process, in stokehold, through Water Quenching, is generally particulate matter, is generally canescence, is neutral, has vesicular structure, mostly is vitreum, has good pozzolanic activity.Its chemical composition is divided by SiO

2o etc.1 ton of yellow phosphorus of every production approximately will discharge 8～10 tons of waste residues, according to incompletely statistics, the quantity discharged of phosphorus slag is 1078～1,300 ten thousand tons/year in the world, so large quantity discharged all air storages of major part except small portion regeneration, both taken tract, can, to environment, human health be worked the mischief again.
For solving the pollution problem of phosphorus slag, people have researched and developed the multiple method of utilizing phosphorus slag to produce material of construction.As utilize phosphorus slag to produce the method that vitrified brick, haydite, ceramic tile etc. need high temperature sintering, for another example utilize punching press, the mode such as steam-cured to prepare non-burning brick method, as mono-kind of the number of patent application patent of invention < < that is 201110208348.6 utilizes novel steamed brick that using waste phosphorus slag produces and preparation method thereof > >.
Phosphorus mine tailing and phosphorus slag belong to the waste residue that phosphate rock resource utilization produces afterwards, much phosphorous chemical industry enterprise has this two kinds of industrial residues simultaneously, but in current disclosed technical scheme, there is no the report that both are fully utilized together, particularly there is no the method for the phosphorus mine tailing that a large amount of utilizations are thinner.
In addition, non-burning brick water tolerance prepared by prior art is poor, and especially lean property waste material doping is particularly serious when higher, and this just causes certain limitation to its application, and may cause waterproofing work to drop into increase.
