Description
Technical field
The invention belongs to building material technical field, and in particular to a kind of anti-static non-ignition composite and its preparation side
Method.
Background technology
With the fast development of Structural ceramics industry, the quantity of shraff, especially tile polished waste is more and more, according to
Statistics:The year output estimation of national tile polished waste is 5,000,000 tons or so (shraff total amounts estimated 10,000,000 tons), so
Substantial amounts of shraff can not solve with simple burying method, meanwhile, the shraff of bulk deposition squeezes at present
Soil is accounted for, serious pollution is caused to environment such as water, air and soil.Flyash is the coal dust and bastard coal by wearing into certain fineness
Stone flour collects after high-temp combustion the fine ash come in fluidized-bed combustion boiler, it be the larger industrial residue of the current discharge capacity in China it
One, substantial amounts of flyash is untreated, will produce airborne dust, pollutes air, river can be caused to silt up if being discharged into water system, and wherein
Toxic chemical substance human body and biology can also be damaged.Mineral have both been saved using ceramic tile polishing waste material and flyash
Raw material resources, natural environment is also protected, embody the meaning of important environmental protection and energy-saving and emission-reduction.
In industrial building, for example, military project manufacture, liquefied petroleum-gas station, Gas Production factory, oiling storehouse, petrol station harbour and its

The requirement of material is very tight, must have antistatic, misfiring property.Material of misfiring at present can be divided into three classes, i.e.,:Misfire metal
The non-ferrous metal such as ground, its material typically conventional copper coin, aluminium sheet makes;The ground of organic material of misfiring manufacture, such as pitch, wood
The layings such as material, plastics, rubber;Inorganic material of misfiring ground, it is using misfire cement stone sand, pea gravel concreten, water mill
The inorganic material such as stone manufacture, and aggregate can be selected lime stone, marble, dolomite etc. and misfire material.Misfire and metal and do not send out
Fiery inorganic material ground is not resistant to chemical etching;Misfire the poorly conductive of organic material, there is insulation function, therefore to guiding
Electrostatic is unfavorable, also to fire-proof and explosion-proof unfavorable.
Presently used antistatic floor has all steel antistatic raised floor, aluminium alloy antistatic floor, and chemically-resistant is not rotten
Erosion;Compounded antistatic floor, the fire-protection rating of straight paving formula pvc antistatic floors are low;Ceramic antistatic floor and static-electricity proof tile
Mohs' hardness it is too high, friction, impact when easily produce spark, to fire-proof and explosion-proof unfavorable.The work(of antistatic floor used
Energy property is all very single.
The content of the invention
It is an object of the invention to provide a kind of anti-static non-ignition composite, has permanent antistatic, misfires, resistance toization
The advantages of learning corrosion, available for military project manufacture, liquefied petroleum-gas station, Gas Production factory, oiling storehouse, petrol station harbour and other are inflammable
The regions such as explosive engineering, warehouse, there is the occasion of fire-proof and explosion-proof particular/special requirement working environment, eliminate the shadow to production environment
