Light cellular partition board that a kind of fluorite mine tailing/steel-making slag powder is compound and preparation method thereof
Technical field
The present invention relates to building material field, be specifically related to compound light cellular partition board of a kind of fluorite mine tailing/steel-making slag powder and preparation method thereof.
Background technology
Light cellular partition board is made up of various industrial waste residues such as innoxious phosphogypsum, lightweight slag, flyash, a kind of novel energy-conserving walling material forming through the maintenance of frequency conversion steam pressurized, the walling that it is a kind of external form as the cassette ceiling, but there is male and female falcon groove on its both sides, when installation, only sheet material need be erected, male and female falcon is coated after a small amount of filleting mortar assembled.It has the advantages such as quality is light, intensity is high, multiple environmental protection, heat insulating, sound insulation, breathing damping, fire prevention, rapid construction, reduction body of wall cost, so enjoy favor in architecture indoor finishing field, but the shortcomings such as the light cellular partition board ultimate compression strength using is in the market low, tensile strength weak, anti-cracking performance and hanging ability is not good, production cost is high, sound-insulating weak effect.
Summary of the invention
Object of the present invention is just to provide compound light cellular partition board of a kind of fluorite mine tailing/steel-making slag powder and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
The compound light cellular partition board of a kind of fluorite mine tailing/steel-making slag powder, it is characterized in that, made by the raw material of following weight part: cement 9-14, polyethylene fibre 11-15, geopolymer 13-18, NS-780 redispersable latex powder 10-13, steel-making slag powder 19-24, dicumyl peroxide 1-2, fluorite mine tailing 17-19, oyster shell whiting 13-16, polypropylene fiber 1-4, Pomegranate Leaf 15-19, peach gum 4-7, auxiliary agent 3-6, suitable quantity of water.
Described auxiliary agent is made up of following raw materials in part by weight: volcanic ash 6-9, Sodium sulfate anhydrous.min(99) 2-5, magnesium chloride 3-5, magnesium oxide 2-4, polyvinyl alcohol 0.2-0.5, Starso 0.03-0.07, sodium aluminate 0.05-0.6, tartrate 0.8-2.1, organosilicon crylic acid latex 2.1-4.3, 2-imidazolidone 0.04-0.09, silicon carbide 1-3, accelerant CZ 0.03-0.05, Syzygium aromaticum stem oil 1.2-3.2, its preparation method is in 50% magnesium chloride solution, to add the magnesium oxide powder inorganic gel agent that stirs to obtain, then other leftover materials are pulverized and mixed, add suitable quantity of water and stir 30-40 minute pulping, granulation, balling-up particle diameter is at 2-5mm, dry and get final product.
Described geopolymer is the novel inorganic silicon-aluminum gelatinized material in a kind of structure with the network-like keyed jointing structure of space three-dimensional, does not adopt " two mills one burn " calcining process of consumption of natural resource and the energy in preparation technology, does not substantially discharge CO
2.The starting material wide material sources of geopolymer, easy to prepare, energy consumption is little, has higher mechanical property and very excellent resistance to elevated temperatures simultaneously, broken through the use range of traditional portland and alkali slag cement.The present invention, by geopolymer replacing partial cement, not only can reduce cost energy-conserving and environment-protective, and can not weaken again the pectisation of cement.
The preparation method of the compound light cellular partition board of described a kind of fluorite mine tailing/steel-making slag powder, is characterized in that comprising the following steps:
(1) Pomegranate Leaf is sent in charring furnace, at 485-605 DEG C, 3-4 hour is processed in charing, takes out, and is ground into powder, makes it seethe spray form peach gum under condition, then add NS-780 redispersable latex powder stirring and evenly mixing to the powder of gained in air blast;
(2) get geopolymer and put into the hydrochloric acid soln of 8-12% and soak 4-5 hour, filter and take out, use clear water repetitive scrubbing, dry, be added to the water, meanwhile, add oyster shell whiting, grinding obtains slurry;
(3) steel-making slag powder, fluorite mine tailing are calcined at 600-828 DEG C after 3-6 hour and taken out, pulverize, add polyethylene fibre, polypropylene fiber to stir 5-10 minute;
(4) step (1), (2), (3) reaction mass and the pulverizing of other leftover materials are added to suitable quantity of water stirring and evenly mixing and obtain slip, the slurry making is added to wall slab squeezing former moulding, cutting, natural curing, to obtain final product.
The present invention has following beneficial effect: the present invention will add in starting material after the pyroprocessing such as fluorite mine tailing, steel-making slag powder, Pomegranate Leaf, the obnoxious flavour such as formaldehyde, PM2.5 particle in can absorbed air, lightweight, the feature such as intensity is high, insulation, sound insulation, fire prevention that the partition plate making has.
Embodiment
The described compound light cellular partition board of a kind of fluorite mine tailing/steel-making slag powder, it is characterized in that, made by the raw material of following weight part: cement 9, polyethylene fibre 11, geopolymer 13, NS-780 redispersable latex powder 10, steel-making slag powder 19, dicumyl peroxide 1, fluorite mine tailing 17, oyster shell whiting 16, polypropylene fiber 1, Pomegranate Leaf 17, peach gum 4, auxiliary agent 3, suitable quantity of water.
Described auxiliary agent is made up of following raw materials in part by weight: volcanic ash 6, Sodium sulfate anhydrous.min(99) 2, magnesium chloride 3, magnesium oxide 4, polyvinyl alcohol 0.2, Starso 0.03, sodium aluminate 0.4, tartrate 1.8, organosilicon crylic acid latex 2.1,2-imidazolidone 0.04, silicon carbide 1, accelerant CZ 0.03, Syzygium aromaticum stem oil 2.2, its preparation method is in 50% magnesium chloride solution, to add the magnesium oxide powder inorganic gel agent that stirs to obtain, then other leftover materials are pulverized and mixed, add suitable quantity of water and stir 30-40 minute pulping, granulation, balling-up particle diameter, at 2-5mm, is dried and be get final product.
