Description

One kind prepares aluminum oxide-silicon carbide composite porous ceramic using aluminium silicon systems industrial residue Method
Technical field
The invention belongs to porous ceramic film material and open pit mining technical field.Provide a kind of industrial using aluminium silicon systems The method that waste residue prepares aluminum oxide-silicon carbide composite porous ceramic.
Background technology
China is industrial power, and it is more that crude steel annual production accounts for Gross World Product half, while is also that copper, aluminium, lead, zinc etc. are main Want the major producing country of nonferrous metal product.Certainly, these reflect the progress of China's economy and the enhancing of national power.It is but another On the one hand, with the development of the heavy industry such as coal, metallurgy, electric power, people have to face while economic development bonus is enjoyed To this worsening problem of environment.
Such as the fast development of power industry, while providing convenient for people so that flyash discharge capacity sharply increases. Substantial amounts of flyash not only pollutes air, and stockpiling is also required to take substantial amounts of soil, brought to daily life many Inconvenience.If only doing it simple burial or stacking, then surrounding environment can be caused seriously to pollute after long-time.Separately Outside, as slag, red mud, tile polished waste are as inevitable derivative in process of manufacture, also environment is caused huge Big pressure.Steel plant's caused slag amount in steelmaking process is about the 15%~20% of output of steel, these industrial residues Accumulation not only take substantial amounts of processing cost, and secondary pollution easily is caused to environment.Therefore, green processing and efficiently profit It is extremely urgent with these industrial residues.
Porous ceramics refers to be fired into a kind of ceramic material with high porosity under high temperature, in preparation process often Sintering aid, foaming agent and pore creating material are used to form required hole and pore structure.Due to its special material and structure, Make the excellent properties of its existing traditional ceramics, good also with high-specific surface area, low-density, lower thermal conductivity, sound-absorption and heat-insulation etc. Performance.Therefore, porous ceramics is widely used in fields such as metallurgy, chemical industry, medicine and fire-fightings, turns into the heat of Material Field research One of door direction.
Many industrial residues are all aluminium silicon systems oxides, and Al2O3And SiO2It is the raw materials for production for commonly using ceramics again, therefore, Aluminium silicon systems industrial residue is adapted to prepare aluminum oxide-silicon carbide composite porous ceramic.Wherein as flyash contains substantial amounts of manosil AS Salt, also a certain amount of quartz and calcium oxide etc., can be used to make mullite densification and porous ceramics, Sialon ceramics etc..Polishing Brick waste residue is also aluminium silicon systems oxide, and also containing some abrasive materials SiC, this slag can be decomposed to form into gas in high temperature sintering process Hole, the porous functional ceramic with performances such as good mechanics, calorifics, acoustics can be prepared using the characteristic.In recent years, with society Attention to environmental issue, the green processingization of industrial residue have certain development and progress, but how to prepare performance and Crowd, the porous ceramics of high added value, it is still current ceramic field and open pit mining field urgent problem to be solved.
The content of the invention
Present invention seek to address that above mentioned problem, there is provided one kind prepares aluminum oxide-silicon carbide using aluminium silicon systems industrial residue The method of composite porous ceramic.Utilize present invention can apply to the processing of each eka-aluminum silicon systems industrial residue and efficiently, it is both again sharp With industrial waste, turn waste into wealth；Environment is protected again, is killed two birds with one stone.
The technical step of the present invention is as follows：
(1) batch mixing.Weigh a certain amount of aluminium silicon systems industrial residue and carbon dust, then the pore creating material of additional mass fraction 0~40% With 3~8% binding agents, 10~30h of ball grinder ball milling using absolute ethyl alcohol as medium is placed in；
(2) dry.Sample after ball milling is dried to obtained ceramic raw material at a temperature of 70~120 DEG C；
(3) it is molded.It is then that sample after drying is compressing, obtain base substrate；
(4) sinter.The base substrate suppressed is put into high temperature furnace it is passed through protection and gas and begin to warm up, heating rate is controlled 5 ~15 DEG C of min-1, to 2~10h is incubated at 1400~1700 DEG C, aoxidized after subsequent temperature control to furnace cooling after 1000 DEG C Aluminum/silicon carbide composite porous ceramic.
The aluminium silicon systems industrial residue is flyash, red mud, slag, iron ore tailings, boron mud, gangue, aluminium section bar plant One or more in waste residue, shraff；
The carbon dust is the one or more in activated carbon, carbon black, coke, coal dust；
For the average grain diameter of the aluminium silicon systems industrial residue through handling to below 1mm, pore creating material and binding agent are technical pure；
The pore creating material selects SiC, and binding agent selects phenolic resin；
The ball-grinding machine is planetary ball mill, and speed setting is in 300~500rmin-1In the range of, unidirectional operation, often Operation 5h rests 1h；
The molding mode is one kind in compression molding, isostatic pressing, and briquetting pressure is 100~300MPa；
The protective gas is high-purity Ar gas；
The high temperature furnace is one kind in chamber type electric resistance furnace, tube type resistance furnace, tunnel cave.
The beneficial effects of the present invention are：Raw material is cheap and easy to get, is derived from industrial residue, and porous pottery is prepared with industrial residue Porcelain, not only turn waste into wealth and save resource, also solve waste residue occupation of land and the pollution problem to environment, there is significant economic effect Benefit and environmental benefit.In addition, flow of the present invention is convenient, process operability is strong, equipment requirement is low, possessing commercial introduction completely may Property.And with this technology prepare porous ceramics hole rate it is suitable, the superior such as intensity, can be used as filtering, sound insulation, it is heat-insulated, The materials such as fire-fighting.
