Description
Technical field
The present invention relates to a kind of foam glass and its preparation side with basalt glass grog and CRT panel glass as main material
Method, belongs to glass heat-insulating field of material technology.
Background technology
Foam glass is a kind of by cullet powder, foaming agent, property-modifying additive and foamed promoter etc., through finely divided
After uniform mixing, then through the melting of middle temperature, foaming, foam stabilizing, annealing and made by contain the inorganic non-of substantial amounts of uniform bubble
Metal glass material.The physico-chemical property of unorganic glass and its uniform separated foam for having determine that this material has
Density is low, thermal conductivity factor is little；Do not burn, it is indeformable, can use in the wide temperature range of low temperature to high temperature；Chemical stability
Height, is amenable to the erosion of medicine, also without putrefaction of not deteriorated；Airtight, non-hygroscopic water suction, it is not necessary to worry all the year round using rear heat-insulated
The good characteristic of performance depreciation；In addition, its also anti-oxidant, weathering, will not be by rat eaten of damaging by worms.So, foam glass is wide
The general insulation cold insulation applied in every field such as chemical industry, petrochemical industry, Tunnel Engineering and sound absorption.
Basalt is the solid or powdered scrap that discharge after exploitation, sorting ore and temporarily can not be utilized, and is wrapped
Basalt mine tailing and plant tailing are included, wherein mill tailings includes that the association country rock for having produced is low-grade with what midway was rejected
Ore；Plant tailing includes that using certain technique the mineral waste (mine tailing) discharged after mechanical washing ore, these mine tailings are used
Pipeline to Tailings Dam is deposited.For this purpose, a large amount of farmlands and forest land are occupied, ecology receives destruction, it is difficult to recover.
Basalt, as a kind of natural ore, is the primary raw material for producing cast stone.Cast stone has higher resistance toization
Learn corrosivity and acid resistance, with larger hardness and mechanical strength, be widely used in chemical industry, metallurgy, electric power, coal, building materials,
The industrial department such as weaving and light industry.Basalt is production basalt paper, lime volcanic rock clinker-free cement, dalle, artificial
The raw material of fiber, or the energy-conservation raw material in ceramic industry.In addition, basalt is to repair highway, railway, stone used by airfield runway
Best material in material, with crushing resistance it is strong, crush values are low, corrosion resistance is strong, asphalt adhesion Black Warrior stone, Black Warrior stone has resistance to
Mill, draft amount is few, electric conductivity is poor, crushing resistance is strong, crush values are low, corrosion resistance is strong, asphalt adhesion the advantages of.
Chemical composition in China's basalt ore deposit mainly includes：Silica, alundum (Al2O3), di-iron trioxide, oxidation
Calcium, magnesia and potassium oxide etc., the total amount of these oxides accounts for more than the 96wt% of whole basalt ore deposit oxide components, the above
Composition great majority are utilizable oxide when preparing porous thermal insulating glass material (foam glass) for building.
CRT (cathode ray tube, CRT) is part maximum in computer monitor and television set, accounts for such setting
The 2/3 of standby gross mass, glass accounts for the 85% of CRT gross masses, and its structure is bored and the part group of glass tube neck three by glass screen, glass
Into.Containing harmful material in discarded CRT glass, process is not good at that environment will be caused serious pollution, therefore discarded CRT glass
The regenerated resources of glass are treated as a problem demanding prompt solution, and its post processing research is also paid much attention to.Discarded CRT
Glass can recycle material as one kind, for preparing foam glass or building thermal insulation material.According to statistics China's negative electrode is penetrated
Spool report peaked in 2012, and 4000~50,000,000 useless CRT will be produced every year.It is with waste cathode-ray tube (CRT)
Foam glass made by primary raw material is except with fire prevention, waterproof, sound absorption, suction is radiated, do not fired, not aging, mechanical strength is high etc.
Outside the excellent properties of foam glass, undoubtedly also there is extraordinary economic benefit and social benefit.It is highly suitable as building to protect
Adiabator is applied to external wall and roof heat insulation.
Patent CN101955319A provides a kind of method for preparing foam glass using discarded fiberglass products, will
Discarded glass mat and fiberglass gridding cloth is ground into glass dust, addition carborundum, antimony oxide, sodium sulphate, fluorine

Foam glass.Foam glass is in this way prepared, can be turned waste into wealth, environmental protection, but product strength is relatively low.Patent
CN101602574A provide a kind of preparation method of high-intensity foam glass, by cullet, calcium carbonate, borax, sodium nitrate and
Refractory fibre be encased in ball milling mixing in ball grinder be uniformly fitted into afterwards in mould and enter preheated in foaming furnace, foaming, foam stabilizing,
The stages such as annealing are obtained foam glass.The high refractory fibre of refractory temperature height, intensity is added in foam glass, so improve
The mechanics energy of foam glass.But production cost is also increased while mixing refractory fibre, so needing a kind of by changing
Become method of the glass ingredient to improve strength of glass.Patent CN102001831A provides a kind of preparation of full closed pore foam glass
Method, cullet, flyash, camwood knag is put in ball mill and is milled to and can be formed batch by 200 mesh standard sieves；Will
Batch and atomization distilled water are put in pan-type pelletizer and prepare spherical particle；Prepared spherical particle is loaded into fireproof die
In；Finally fireproof die is moved in foaming furnace together with spherical particle and fires to obtain full closed pore foam glass.Obtained in this method
Sealed porosity rate is high, and air vent aperture is evenly distributed, and improves heat-insulating property.But need to increase granulation process, make complex process, into
This increase.
Nearly all it is with a kind of discarded glassware grog in the existing method for preparing foam glass material and technology
