Cullet is as a kind of common solid waste, present stage China discarded glass reclaim after, generally first add some mineral material high-temperature fusion, the glass of plastotype Cheng Xin again, this recycling mode needs high temperature energy consumption very large, under current China energy-intensive situation, the environmental friendliness recycling mode of developing a kind of new low-carbon (LC) seems particularly important.
Geopolymer is the inorganic polymer material that a class has amorphous three-dimensional netted silicon-oxy tetrahedron and aluminum-oxygen tetrahedron structure, has the part advantage of inorganic materials and organic polymer concurrently.This material is having the excellent properties such as physical strength is high, acidproof, high temperature resistant, fire prevention, corrosion-resistant, weather resistance is strong because of its special structure.On the other hand, due to silicon-aluminium component that cullet contains some amount, can be used as in theory preparing the starting material of geopolymer.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of burning free type geopolymer multicellular glass, and the method be take waste ceramic as raw material, does not add other natural materialss, has reduced cost, has saved resource, has improved the recovery utilization rate of waste ceramic.
The preparation method of a kind of burning free type geopolymer multicellular glass of the present invention, it comprises the following steps:
1), by common scrap glass sheet grinding 20 ~ 30 minutes in ball mill, levigate cullet powder can be crossed 100 mesh sieve can;
2) by scrap glass powder 100 weight parts, alkali-activator 30 ~ 60 weight parts, whipping agent 1 ~ 5 weight part, adds in concrete-agitating pot and stirs;
3) slurry stirring is poured in mould, then put into 60 ± 5 ℃, maintenance in the concrete curing box of relative humidity 99%, the demoulding after 24 hours.And then put into maintaining box maintenance certain hour and can obtain multicellular glass.
Step 2) described alkali-activator is a kind of in water glass, potassium silicate, sodium hydroxide, potassium hydroxide solution, and described water glass and the modulus of potassium silicate are between 1.0 ~ 2.0, and sodium hydroxide and potassium hydroxide solution concentration are 5 ~ 15mol/L.Whipping agent is aluminium powder or hydrogen peroxide.
Step 3) maintenance certain hour specifically refers to 28 days.
Preparation technology's main technological route of the present invention is: take cullet powder as main raw material, under the alkali excitation mechanism of alkali-activator, be prepared into geopolymer slurry, introduce whipping agent foaming at the uniform hole of the inner generation of geopolymer simultaneously.This slurry is entered to mold forming, and at 60 ℃, in the maintaining box of relative humidity 99%, maintenance is 28 days, can obtain that intensity is high, light weight, multicellular glass that thermal conductivity is low.
It is main fabricating technology that the present invention adopts alkali excitation principle, does not need the high-temperature technology of 750 ~ 900 ℃, reduces energy consumption; And take cullet as raw material, do not add other natural pit woods, reduce costs and economize on resources, improve the recovery utilization rate of cullet.Material of the present invention is inorganic materials, has overcome organic insulation material easy firing, inflammable critical defect.A large amount of unformed 3 D stereo reticulated structures are contained in its inside, have that thermal conductivity is low, heat-proof quality good, fire performance is good, a feature such as long service life, ageing-resistant performance are good.Raw material has replaced other natural matters such as perlite, float stone, mica with cullet, reduce resource consumption, has reduced production cost, has promoted the comprehensive utilization of solid waste.
