Background technology
Light cellular partition board is made up of various industrial waste residues such as innoxious phosphogypsum, lightweight slag, flyash, through a kind of novel energy-conserving walling material of frequency conversion steam pressurized maintenance, 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, only sheet material need be erected during installation, 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 shortcomings such as the light cellular partition board ultimate compression strength used in the market is low, tensile strength is 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 light cellular partition board of a kind of slag/flyash compound and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
The light cellular partition board of a kind of slag/flyash compound, it is characterized in that, be made up of the raw material of following weight part: cement 10-14, nanoscale silicon powder 11-15, geopolymer 15-18, slag 18-25, flyash 19-24, dicumyl peroxide 0.7-1.6, Fructus Zanthoxyli oil 4-7, magnesium hydroxide 0.4-0.8, zinc sulfate 0.6-0.9, magnesium sulfate 1-2, large waste of flax 16-18, leaf of Yellow cinnamon 14-16, 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 in 50% magnesium chloride solution, adds magnesium oxide powder to stir to obtain inorganic gel agent, then other leftover materials are pulverized mixing, 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 a kind of structure with the network-like bonded structure of space three-dimensional, does not adopt " two mills one burn " calcining process of consumption of natural resource and the energy, substantially do not discharge CO in preparation technology
2.The raw material sources of geopolymer is extensive, easy to prepare, energy consumption is little, has higher mechanical property and very excellent resistance to elevated temperatures simultaneously, breaches the use range of traditional portland and alkali slag cement.The present invention, by geopolymer replacing partial cement, not only can be reduced cost energy-conserving and environment-protective, and can not weaken the pectisation of cement again.
The preparation method of the light cellular partition board of described a kind of slag/flyash compound, is characterized in that comprising the following steps:
(1) large waste of flax, leaf of Yellow cinnamon are sent in charring furnace, at 485-605 DEG C, charing process 3-4 hour, takes out, is ground into powder, powder to gained makes it seethe spray form Fructus Zanthoxyli oil under condition in air blast, then adds dicumyl peroxide stirring and evenly mixing;
(2) get the hydrochloric acid soln that geopolymer puts into 8-12% and soak 4-5 hour, filter and take out, use clear water repetitive scrubbing, dry, be added to the water, meanwhile, add nanoscale silicon powder, magnesium sulfate, zinc sulfate, grinding obtains slurry;
(3) slag, flyash are calcined at 600-828 DEG C after 3-6 hour and take out, pulverize;
(4) step (1), (2), (3) reaction mass and the pulverizing of other leftover materials are added suitable quantity of water stirring and evenly mixing and obtain slurry, obtained slurry is added wall slab squeezing former shaping, cutting, natural curing, to obtain final product.
The present invention has following beneficial effect: the present invention utilizes industrial residue and agricultural wastes in a large number, production cost is low, there are good economic results in society, the advantages such as obtained light cellular partition board long service life, not easy to crack, heat is not yielding, can prevent fires, are adapted to make non-load bearing partition plate under construction and use.
Embodiment
