Description
Technical field
The present invention relates to field of foamed ceramics preparation, and in particular to a kind of Light foam ceramic material and preparation method thereof.
Background technology
With social economy and the fast development of ceramic industry, ceramic industry waste material is increasing, not only to urban environment
Exert heavy pressures on, and also limit the sustainable development of development and the ceramic industry of urban economy, so ceramic industry is given up
The processing of material is extremely important with utilizing.At present, with producing level than relatively low, a large amount of waste residues squeeze for the processing of China's ceramic industry waste material
Arable land is accounted for, is contaminated water and air.With the increase of ceramics yield, the quantity of waste material is more and more, according to incomplete
Statistics, the annual production of national shraff estimate that at 10,000,000 tons or so so substantial amounts of shraff has not been simply to fill out
Soluble problem is buried, with the growing and social progress of economy, the accumulation of shraff ties up soil, fine powder
Dirt influences the quality of local air, and the landfill labor intensive material resources of shraff, goes back polluted underground water matter, how to become give up into
Treasured, shraff progress recycling is rationally utilized, has become the task of top priority of science and technology and environmental administration.
Shraff mainly produces during Ceramic Production, such as shaping, drying, glazing, carrying and roasting
Process.The chemical composition of shraff is mainly SiO2、Al2O3、CaO、MgO、K2O、Na2O and a small amount of Fe2O3Deng.By waste ceramic
Material is used as primary raw material, prepares foam ceramic material（Such as foam thermal insulation brick, laundry stone, light ceramic）It is a kind of recycling profit
With more sufficient technical method.But using current technical method, it is difficult to which low unit weight is made（Less than 0.4g/cm3）, low lead
Hot coefficient（Less than 0.15W/ (mk)）, high withstand voltage intensity（More than 5MPa）Light foam ceramic material.It is main both at home and abroad at present
Three kinds of methods are used, foam ceramic material is prepared using shraff as primary raw material.First method is with waste ceramic
Based on material, clay minerals, flyash, quartzy class mineral, feldspathoid etc. are separately added, then be subject to appropriate additive, foaming
Agent（Graphite, carbide, boride, carbonate, sulfate etc.）And grinding aid, after broken, ball milling, drying and shaping,
10-60min is heat-treated under the conditions of 1000-1300 DEG C to be made, and is difficult that the bubble of lightweight and low thermal conductivity is made using the method still
Foam ceramic material；Second method is based on shraff, separately adds other natural minerals, waste material, waste residue and industry addition
Agent etc. is as composition conditioning agent, in high temperature furnace（More than 1300 DEG C）Melt is melt into, forms porous body through bubbling, quenching obtains
Foam ceramic material, or melt is through quenching and broken, then with additive and foaming agent etc. be blended, ball milling, drying and shaping, so
By high-temperature heat treatment（800-1100℃）Foam ceramic material is made in foaming, because the method is needed by high temperature melting process,
Therefore consuming energy is larger, and complex process；The third method is that another addition is given up or cullet, industry based on shraff
Additive and foaming agent etc., through broken, ball milling, drying and shaping, foamed ceramics material is made in 800-1100 DEG C of heat treatment foaming
Material, but influenceed by material mineral speciality, remain difficult to that lightweight, the foam ceramic material that thermal conductivity factor is low and intensity is high is made.
In a word, the deficiency of some is still suffered from shraff is primary raw material preparation Light foam ceramic material at present：
Such as industrial energy consumption, big, prepared material is unable to reach low unit weight（Less than 0.4g/cm3）, low thermal conductivity（Less than 0.15W/
(m·k)）, high withstand voltage intensity（More than 5MPa）Deng performance requirement.
