Description
Technical field
The present invention relates to a kind of with basalt glass grog and CRT panel glass multicellular glass that is main raw material and preparation method thereof, belong to glass heat-insulating field of material technology.
Background technology
Multicellular glass is a kind of by glass cullet powder, whipping agent, property-modifying additive and foamed promoter etc., after the broken and Homogeneous phase mixing of fine powder, then through in warm melting, foaming, steady bubble, annealing and the inorganic non-metallic glass material containing a large amount of uniform bubble made.The physico-chemical property of unorganic glass and its uniform separated foam of having determine this material and have that density is low, thermal conductivity is little; Do not burn, indeformable, can use in the wide temperature range of low temperature to high temperature; Chemical stability is high, can stand the erosion of medicine, also without putrefaction of not deteriorated; Airtight, non-hygroscopic water suction, need not worry the good characteristic using rear heat-proof quality to degenerate all the year round; In addition, it is anti-oxidant, weathering also, can not by rat eaten of damaging by worms.So multicellular glass is widely used in insulation cold insulation and the sound absorption of the every field such as chemical industry, petrochemical industry, Tunnel Engineering.
Basalt discharges and the solid that temporarily can not be utilized or powdered solid fuel after exploitation, sorting ore, comprises basalt mine tailing and plant tailing, and wherein mill tailings comprises the low grade ore of association country rock and the midway rejecting of having exploited out; Plant tailing comprises the certain technique of employing, and the mineral waste (mine tailing) of discharging after mechanical washing ore, these mine tailings are piped to Tailings Dam and deposit.For this reason, a large amount of farmland and forest land occupied, ecology receives destruction, be difficult to recover.
Basalt, as a kind of natural ore, is the main raw material of production cast stone.Cast stone has higher chemical resistance and acid resistance, has larger hardness and physical strength, is widely used in the industrial sectors such as chemical industry, metallurgy, electric power, coal, building materials, weaving and light industry.Basalt is the raw material producing basalt paper, lime volcanics clinker-free cement, dalle, regenerated fiber, or the energy-conservation raw material in ceramic industry.In addition, basalt repairs best material in highway, railway, airfield runway building stones used, have that crushing resistance is strong, crush values is low, erosion resistance is strong, asphalt adhesion Black Warrior stone, Black Warrior stone has wear-resisting, the advantage such as draft amount is few, poor electric conductivity, crushing resistance are strong, crush values is low, erosion resistance is strong, asphalt adhesion.
Chemical composition in China's basalt ore deposit mainly comprises: silicon-dioxide, aluminium sesquioxide, ferric oxide, calcium oxide, magnesium oxide and potassium oxide etc., the total amount of these oxide compounds accounts for more than the 96wt% of whole basalt ore deposit oxide components, and above composition great majority are utilizable oxide compound during preparation porous thermal insulating glass material (multicellular glass) for building.
CRT (cathode ray tube, CRT) is parts maximum in computer monitor and televisor, and account for 2/3 of this kind equipment total mass, glass accounts for 85% of CRT total mass, and its structure is bored by glass screen, glass and glass tube neck three part forms.Containing harmful material in discarded CRT glass, process is not good at causing serious pollution by environment, and therefore the renewable resource of discarded CRT glass are treated as a problem demanding prompt solution, also pays much attention to its aftertreatment research.Discarded CRT glass can as a kind of recycle material, for the preparation of multicellular glass or building thermal insulation material.China's cathode tube report peaked in 2012 according to statistics, every year by generation 4000 ~ 5,000 ten thousand useless CRT.The multicellular glass made for main raw material with waste cathode-ray tube (CRT) except having fire prevention, waterproof, sound absorption, suction radiation, do not fire, except the excellent properties of the multicellular glass such as not aging, physical strength is high, undoubtedly also there is extraordinary economic benefit and social benefit.Be suitable as very much building thermal insulation material and be applied to external wall and roof heat insulation.
Patent CN101955319A provides a kind of method utilizing discarded fiberglass products to prepare multicellular glass, discarded glass mat and fiberglass gridding cloth are ground into glass powder, add silicon carbide, antimonous oxide, sodium sulfate, sodium fluoroaluminate, SODIUMNITRATE, cobalt sesquioxide, in ball mill, form compound; Admixtion is loaded in heat-resisting die and is fired into multicellular glass.In this way prepare multicellular glass, can turn waste into wealth, protection of the environment, but product strength is lower.Patent CN101602574A provides a kind of preparation method of high-intensity foam glass, glass cullet, calcium carbonate, borax, SODIUMNITRATE and refractory fibre is encased in ball milling in ball grinder and mixes in rear loading mould and entered in foaming furnace and obtain multicellular glass through the stage such as preheating, foaming, steady bubble, annealing.The refractory fibre that refractory temperature is high, intensity is high is added, so improve the mechanics energy of multicellular glass in multicellular glass.But too increase production cost while mixing refractory fibre, so need a kind of method improving strength of glass by changing glass ingredient.Patent CN102001831A provides a kind of preparation method of full closed pore foam glass, and glass cullet, flyash, camwood knag are put into ball mill and be milled to by 200 mesh standard sieves, forms admixtion; Admixtion and atomization distilled water are put into pan-type pelletizer and prepares spherical particle; Prepared spherical particle is loaded in fireproof die; Finally fireproof die is moved in foaming furnace together with spherical particle and fire to obtain full closed pore foam glass.The sealed porosity rate that this method obtains is high, and air vent aperture is evenly distributed, and improves heat-insulating property.But need to increase granulation process, make complex process, cost increases.
Existingly preparing in the technique and method of foam glass material, is nearly all for main raw material, prepare foam glass product with a kind of discarded glasswork grog (float glass, container glass, CRT panel glass, glass fibre etc.).The weight of discarded glass grog powder can account for more than 90% of whole raw material total mass.At present also not using discarded glass grog and basalt glass jointly as the method for main raw material(s) for the preparation of multicellular glass.
