Description
The present invention relates to utilize the material of construction of industrial abandoned mine slag, be specially that abandoned mine slag magnesium cement compound is fire-retardant, water-proof roofing and low pressure pipeline building slab material for raw material.
Along with industrial expansion, the abandoned mine slag that has every year a large amount of high-quality soils and farmland to be discharged by industrial and mining enterprises takies and pollutes, and becomes big public hazards; Still have 80% various abandoned mine slags not obtain as yet utilizing at present, and this class abandoned mine slag is also constantly increasing.Therefore how to utilize the abandoned mine slag, solve this public hazards, become one of problem that common people pay close attention to.With regard to the situation that present abandoned mine slag is utilized, utilize it maximum as the work of material of construction, wherein especially utilize the building slab material (CN94100939.3) of abandoned mine slag and chloro-magnesium cement Compound Machining, abandoned mine slag consumption, reach as high as 60%, the abandoned mine slag must be utilized, the building slab material of being produced has nontoxic, corrosion-resistant, waterproof, antifreeze, insulation, specious, series of advantages such as with low cost, and can replacing, but its non-flame properties to the deleterious asbestos products of HUMAN HEALTH (as asbestos cement tile), mechanical property and water-intake rate are still not ideal enough.And must not utilize yet without the most of thick slag of pulverizing, make a large amount of useful ferric oxide that wherein contains underuse and discard in vain.
The object of the invention makes full use of abandoned mine slag resource, by improving useless scoriaceous utilization, provides a kind of mechanical property, fire-retardant, roofing that water resistance is good again and the building slab material of low pressure pipeline.
The useless scoriaceous analysis and research of a large amount of industry are shown: oxide compound and bisalt materials thereof such as contained aluminium, iron, calcium, silicon, magnesium in the abandoned mine slag not only have functions such as heatproof, fire prevention, heat insulation, insulation, sound insulation, wear-resisting, waterproof; And be natural stabiliser in the material of construction processing and forming technology, with the abandoned mine slag after selected processing as one of its main constitutive material, can no longer add other stablizer such as added ingredients such as Qi-tonifying prescription, air, defoamer.Warp and the moulding of magnesium cementitious composite, and in its component surface, compound one deck water-repellancy macromolecule resin, the member material of construction that Compound Machining becomes can improve its water-repellancy and mechanical strength greatly, and can further reduce product cost.Abandoned mine slag magnesium cement composite architectural materials of the present invention for this reason is to contain 40～60% selected abandoned mine slag, with chloro-magnesium cement, a small amount of auxiliary chemicals and top layer be the water proof fire retardant construction material that water-repellancy macromolecule resin, strongthener Compound Machining are made.Described selected abandoned mine slag is meant from abandoned mine slag, multifuel combustion slag, flyash, the steel-making waste residue of vitriol works, power station, coal burning boiler, steelworks discharge isolates the lightweight abandoned mine slag that swims in the upper strata through wet concentration, dry or dry and obtain lightweight abandoned mine slag, to remain most of iron content abandoned mine slag then and carry out magnetic separation through magnetic selection method, contain have an appointment 60% ferric oxide, Z 250 in the abandoned mine slag after the magnetic separation, dry or dry and obtain iron content abandoned mine slag; Then lightweight abandoned mine slag and iron content abandoned mine slag are become 120～200 purpose fine powder slags by mixing in 1: 1 and grinding and processing, promptly be processed into selected abandoned mine slag.Also can select the abandoned mine slag of the selected dehydration of the abandoned mine slag fast slag of (phosphorus ore slag) second of phosphate fertilizer plant for use.
Described adding auxiliary chemicals are water-resisting agent, sanitas, fire retardant.Abandoned mine slag magnesium cement composite flame-proof building slab material of the present invention is better formed (weight) and can is:
Selected abandoned mine slag 60% magnesia unslacked 13.9%
26 ° of magnesium chloride brine 22.2% water-resisting agents 1.17%
Sanitas 0.17% fire retardant 0.32%
Waterproof resin 0.94% strongthener 1.3%
Content of magnesia＞75% in an amount of described magnesia unslacked of colorant; Used magnesium chloride Mgcl content＞46% wherein in the aqueous solution that Baume is 26 °; Water-resisting agent optional with in the salicylic acid, toxilic acid, tartrate, sodium tetrapolyphosphate, tripoly phosphate sodium STPP, potassium aluminium sulfate any; Sanitas can be selected in magnesium sulfate heptahydrate, magnesium silicofluoride, SODIUM PHOSPHATE, MONOBASIC, the salt of wormwood any for use; Fire retardant can be selected aluminium dihydrogen phosphate, primary magnesium phosphate, primary ammonium phosphate, acetate emulsion etc. for use; Strongthener be middle alkali, alkali free glass fibre roving interweave screen cloth, wrapping plain, strengthen non-woven fabrics etc.Described surface waterproofing resin is a water-repellancy unsaturated polyester 191,193,189 etc.
Abandoned mine slag magnesium cement composite flame-proof building slab materials processing forming step of the present invention is: the flow process by batching-stirring-composite molding-curing-demoulding-cutting-finished product realizes.
At first selected abandoned mine slag, magnesia unslacked, 26 ° of magnesium chloride brines of Baume, water-resisting agent, sanitas, fire retardant are mixed in described ratio, and the batch mixing that stirs into a paste; In order: the waterproof resin-batch mixing-cloth of reinforcement fibers-batch mixing-cloth of reinforcement fibers-batch mixing-mold composite molding-natural oxygen that contains colorant protects-demoulding-cutting-finished product.
Described mould can be corrugated or flat shape watt mould; Can also be pipe mold, compound formable be ripple or the half-wave shape tile roofing material and the low pressure pipeline construction material of water proof fire retardant thus, as draining, blow-off pipe.
Abandoned mine slag magnesium cement composite flame-proof water proof building construction material of the present invention, owing to adopted selected abandoned mine slag, make main effective component content such as ferric oxide in the abandoned mine slag, Z 250, silicon oxide, calcium oxide obtain relative control with ratio, useless scoriaceous use properties (silicon, iron level are increased) and stability have been improved, thereby the construction material mechanical property flame retardant resistance of itself and magnesium cementitious composite is improved, and the waterproof resin layer of surface recombination has further improved the corrosion-resistant water-repellancy of construction material.The corrugated tile of composite molding thus, not only have corrosion-resistant, do not burn, pollution-free, antifreeze, insulation, appearance looks elegant etc. are better than the glass fibre magnesia oxychloride cement ripple characteristics of watt (can be used as and replace harmful asbestos cement tile), and have than with the rigidity glaze corrugated tile (CN94100939.3) of not selected abandoned mine slag machine-shaping better physical and mechanical property and water-repellancy (table 1); It becomes the low-voltage tube of mould assembly again, shows after testing by (table 2), and its ultimate compression strength all is better than concrete pipe and reinforced concrete pipe above the GB11836-89 regulation, can be used as municipal blow-off pipe and agricultural drain pipe and uses.Thereby improved useless scoriaceous utilization ratio effectively, making it reach 100% can utilize, and has reduced useless scoriaceous public hazards.
