Abstract
The invention discloses a closed-cell foamed ceramic insulation board. The closed-cell foamed ceramic insulation board is prepared from the following raw materials in percentage by weight: 40-70% of gangue, 15-30% of feldspar, 5-15% of quartz, 1-5% of bentonite, 1-5% of waste glass, 1-5% of talcum powder, 0.1-0.5% of a dispersing agent and 0.1-0.5% of a foaming agent. The closed-cell foamed ceramic insulation board is prepared by the following steps: water milling the raw materials in proportion by using a ball mill into slurry being less than 200 meshes and drying the slurry into powder by using a spray-drying tower; sintering the powder at 1,180-1,250 DEC C, foaming and forming ceramic in a tunnel kiln, and preserving heat for 30-60 minutes; cooling to below 50 DEG C in the tunnel kiln and cutting into the closed-cell foamed ceramic insulation board. The closed-cell foamed ceramic insulation board is lightweight, high-strength, high-hardness, heat-preserving and heat-insulating, fireproof and flame-retardant, sound-insulating and noise-reducing, and environment-friendly.
Description
Technical field
The present invention relates to ceramic thermal insulation plate and preparation method thereof, specifically, is a kind of closed pore exterior insulation and preparation method thereof.
Background technology
Coal gangue is the maximum using industrial solid waste of China.Shanxi Province is the large province of coal, has 10% above spoil to be discharged in coal mining, has taken a large amount of land resourcess, and atmospheric environment, edatope, water surrounding, ground environment have been caused the havoc impact.
In recent years, Chinese heavy construction is strong in social response because of the fire failure that lagging material causes, country clear " covil construction heat insulating material for external adopt combustionproperty be A level material ".At present, domestic use architecture exterior wall insulating materials is mostly organic materials: polystyrene, urethane, resol, combustionproperty preferably can only reach the B level, can not meet the requirement of fire protection flame retarding A level.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of coal gangue that utilizes to be closed pore exterior insulation of main raw material preparation and preparation method thereof.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of closed pore exterior insulation is prepared from by each raw material of following mass percent:
Described dispersion agent is a kind of in sodium polyphosphate, water glass and sodium carbonate.
Described whipping agent is a kind of in silicon carbide, coke powder, coal dust and Wingdale.
The preparation method of above-mentioned closed pore exterior insulation comprises the following steps:
(1) by proportioning with raw material below ball mill water mill to 200 order, the spray-dried tower of mud is dried to powder;
(2) powder, through 1180 ℃ of-1250 ℃ of sintering, foaming, one-tenth porcelain, is incubated 30-60 minutes in tunnel furnace;
(3) cooling below 50 ℃ in tunnel furnace, cut into the closed pore exterior insulation.
The invention has the beneficial effects as follows: closed pore exterior insulation of the present invention, light weight, high-strength, high hard, heat insulating, fire protection flame retarding, waterproof and dampproof, sound insulation and noise reduction, environmental protection.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail:
Closed pore exterior insulation of the present invention is prepared from by each raw material of following mass percent:
Described dispersion agent is a kind of in sodium polyphosphate, water glass and sodium carbonate.
Described whipping agent is a kind of in silicon carbide, coke powder, coal dust and Wingdale.
The preparation method of above-mentioned closed pore exterior insulation comprises the following steps:
(1) by proportioning with raw material below ball mill water mill to 200 order, the spray-dried tower of mud is dried to powder;
(2) powder, through 1180 ℃ of-1250 ℃ of sintering, foaming, one-tenth porcelain, is incubated 30-60 minutes in tunnel furnace;
(3) cooling below 50 ℃ in tunnel furnace, cut into the closed pore exterior insulation.
Coal gangue is comprised of multi mineral: kaolinite, feldspar, mica, pyrite, carbonate, rutile etc. are from rawore.Kaolinite Al wherein
2O
32SiO
22H
2O is main ore deposit phase.
Kaolinite is at high temperature:
3Al
2O
32SiO
2Crystalchecked, intensity are high, high temperature resistant, acid and alkali-resistance, as exterior insulation skeleton crystalline structure.The feldspar fusing point is low, and solubilized kaolinite degradation production and impurity phase when liquid phase form melt, at cooling stages sosoloid, separate out acicular mullite, have strengthened exterior insulation resistance to compression, tension and heat shock resistance intensity.
Whipping agent at high temperature oxygenolysis produces gas, and gas is solid-solubilized in melt, forms the closed pore bubble, and it is foamed ceramics that melt cooling forms foamed ceramic.
Cullet and talcum powder fusing point are low, have reduced foamed ceramic and have become the porcelain temperature, have saved mass energy.
Wilkinite can improve the slurry suspension, and cohesiveness and sintering character are preferably arranged.
Dispersion agent reduces the material agglomeration, reduces the water mill water consumption.
